Description

TECHNICAL FIELD

The present invention relates to a material for forming an underlayer film, a resist underlayer film, a method of producing a resist underlayer film, and a laminate.

BACKGROUND ART

In production of a semiconductor device, a multi-layer resist process has been used to achieve a high degree of integration. In this process, typically, a resist underlayer film is firstly formed on a substrate using a material for forming an underlayer film, a resist layer is formed on an upper surface side of the resist underlayer film, and the resist layer is baked and exposed to form a resist pattern. Next, a desired pattern can be obtained by transferring the resist pattern to the resist underlayer film through etching and transferring the resist underlayer film pattern to the substrate.

A shape of a circuit whose dimension size is large is further processed using not only a substrate having a flat shape but also a substrate having an uneven structure preliminarily formed in a large circuit shape in order to form a more complicated circuit, and a multi-patterning method for forming a fine circuit is introduced to the most advanced circuit forming process.

Such a resist underlayer film used in the multi-layer resist process is required to have characteristics such as an embedding property for an uneven portion of a substrate having an uneven structure, the flatness of a surface on a side where a resist is applied, a moderate refractive index, and an extinction coefficient, and characteristics such as excellent etching resistance.

In recent years, pattern refinement has been further promoted in order to increase the degree of integration. In order to deal with such refinement, various examinations have been conducted on structures, functional groups, and the like of compounds used in materials for forming underlayer films (for example, see Patent Document 1).

Meanwhile, in the refinement for pattern formation in order to obtain a high degree of integration, the influence of irregular reflection or stationary waves from a semiconductor substrate in a lithography step carried out using an ArF excimer laser which is a current mainstream has been a major problem. In order to solve this problem, materials with an anti-reflection function as a function required for an underlayer film have been widely examined. As a form in which the anti-reflection function is imparted to an underlayer film, a form in which an uneven structure of a surface of a substrate is embedded with a certain kind of a material and a bottom anti-reflective coating (BARC) is provided on a layer having a flatness or a form in which an anti-reflection function is imparted to a material embedding an uneven structure of a surface of a substrate has been examined.

Particularly in the former material for forming an anti-reflective film, various examinations have been conducted on an organic anti-reflective film formed of a polymer and the like having a light absorbing site. For example, Patent Document 2 discloses a resist underlayer film (anti-reflective film) which is not intermixed with a resist film formed on an upper layer and in which desired optical constants (a refractive index and an extinction coefficient) are obtained and a selection ratio of a large dry etching rate with respect to a resist film is obtained in a case of being exposed to an ArF excimer laser.

SUMMARY OF THE INVENTION

Technical Problem

Recently, the number of cases of forming finer patterns with multi-patterning according to a multi-layer resist method, using a substrate that has a plurality of kinds of trenches and particularly trenches having aspect ratios different from one another, that is, a substrate that has a finer uneven structure, has been increasing. In such cases, a resist layer formed on the uppermost layer is required to have a high flatness in order to accurately transfer the pattern on a reticle. In the recent trend of the pattern refinement, the film thickness of the resist layer has been decreased in order to avoid pattern collapse in a resist development step, and thus the resist layer is more strongly affected by the flatness of the underlayer film. Therefore, a resist underlayer film formed on a substrate having a surface structure into which a resin is unlikely to infiltrate as described above is formed such that these trenches are sufficiently embedded and is required to have a high flatness. In addition, it is considered that a material that does not generate volatile components (outgas) in a baking step after application is preferable.

According to the examination conducted by the present inventors, it was found that a material which satisfies the requirement for the flatness and does not generate volatile components is unlikely to be realized in materials for forming a resist underlayer film of the related art.

In the lithography that employs EUV (abbreviation for extreme ultraviolet, a wavelength of 13.5 nm) which is another fine processing technology, particularly, generation of volatile components (outgas) of a material that forms a resist underlayer film for exposure to high energy ray of EUV light may become a major problem, in addition to the embedding property of the related art even though there is no reflection from a substrate.

Further, in a case where a circuit view is drawn with a line width less than or equal to the wavelength of exposure light, a method of forming a plurality of uneven layers and combining the formed layers has been known. In order to realize such an aspect, a method of forming an intermediate layer on an underlayer film for the purpose of smoothing the uneven layer and further forming a new resist layer thereon can be exemplified.

According to the examination conducted by the present inventors, for example, in a case where this intermediate layer is formed according to a spin coating method or the like, a wrong choice of a solvent may lead to intermixing of the underlayer film with the intermediate film. As the result, it was found that the interface strength between the underlayer film and the intermediate layer may be degraded or the smoothness of the underlayer film may be lost.

The first present invention has been made in consideration of the above-described circumstances, and an object thereof is to provide a material for forming an underlayer film which enables realization of a resist underlayer film having sufficient optical characteristics, etching resistance, excellent flatness, and a suppressed generation of volatile components.

Further, another object of the first present invention is to provide a material for forming an underlayer film, which enables formation of a resist underlayer film having an excellent embedding property for an uneven structure, sufficient optical characteristics, etching resistance, excellent flatness, and a suppressed generation of volatile components on a substrate having a complicated shape.

Further, the second present invention has been made in consideration of the above-described circumstances, and an object thereof is to provide a material for forming an underlayer film which enables realization of a laminate having excellent adhesiveness and excellent flatness without causing intermixing of an intermediate layer with a resist underlayer film.

[First Invention]

Hereinafter, an embodiment according to the first invention will be described.

<Material for Forming Underlayer Film>

A material for forming an underlayer film according to the present embodiment is a material for forming an underlayer film which is used to form a resist underlayer film used in a multi-layer resist process. The material includes a cyclic olefin polymer which has a repeating structural unit [A] represented by Formula (1) and a repeating structural unit [B] represented by Formula (2), and the molar ratio [A]/[B] of the structural unit [A] to the structural unit [B] in the cyclic olefin polymer is greater than or equal to 5/95 and less than or equal to 95/5.

The material for forming an underlayer film according to the present embodiment is a material for forming a layer disposed between a resist layer and a substrate (preferably a substrate having an uneven structure) in a step of producing a semiconductor device. The layer disposed between the resist layer and the substrate is typically referred to as a resist underlayer film, based on a resist layer formed of a resist material that transfers a mask pattern in a photolithography process. The surface of the substrate which comes into contact with the resist underlayer film may be in a state in which a coating film is formed of a low dielectric material, such as a silica (SiO₂) film, a SiCN film, a SiOC film obtained by doping silica (SiO₂) with carbon (C), a methylsiloxane-based organic film (SOG), or a silica insulating film in which minute holes having a size of several nanometers or less are uniformly distributed.

In a case where the material for forming an underlayer film according to the present embodiment contains a cyclic olefin polymer having a repeating structural unit [A] represented by Formula (1) and a repeating structural unit [B] represented by Formula (2), a resist underlayer film having sufficient optical characteristics, etching resistance, excellent flatness, and a suppressed generation of volatile components can be formed. In other words, the material for forming an underlayer film according to the present embodiment can be suitably used for forming a resist underlayer film.

In the material for forming an underlayer film according to the present embodiment, the content of the cyclic olefin polymer having a repeating structural unit [A] represented by Formula (1) and a repeating structural unit [B] represented by Formula (2) is preferably greater than or equal to 50% by mass and less than or equal to 100% by mass, more preferably greater than or equal to 70% and less than or equal to 100% by mass, still more preferably greater than or equal to 80% and less than or equal to 100% by mass, and particularly preferably greater than or equal to 90% by mass and less than or equal to 100% by mass with respect to 100% by mass which is the total content of the material for forming an underlayer film.

It is preferable that the same applies to a cyclic olefin polymer in the second invention described below.

The molar ratio [A]/[B] of the structural unit [A] to the structural unit [B] in the cyclic olefin polymer is greater than or equal to 5/95 and less than or equal to 95/5, preferably greater than or equal to 7/93 and less than or equal to 93/7, more preferably greater than or equal to 10/90 and less than or equal to 90/10, and still more preferably greater than or equal to 15/85 and less than or equal to 85/15.

According to the present inventors, it is considered that in a case where the composition of the cyclic olefin polymer is in the above-described range, the density of elements such as oxygen and sulfur in the main chain of the polymer is in a suitable range, appropriate adhesiveness to the interface of the substrate can be exhibited at the time of embedding the uneven structure of the substrate, occurrence of voids and the like can be suppressed, and the embedding property in an excellent state while maintaining high flatness can be realized. Further, the interaction with the substrate due to the presence of elements such as oxygen and sulfur in the main chain of the cyclic olefin polymer is assumed to become a driving force for the cyclic olefin polymer to enter the fine uneven structure.

In other words, the material for forming an underlayer film according to the present embodiment is formed on the uneven structure of the substrate having the uneven structure and can be particularly suitably used to form an underlayer film for embedding recesses in the uneven structure.

In a case where the ratio [A]/[B] is out of the above-described ranges of the upper limit and the lower limit, the adhesiveness to the interface of the substrate is not exhibited in a cooling process after application to the uneven substrate and baking, and the material is contracted and this may cause defects such as voids.

The cyclic olefin polymer according to the present embodiment can be obtained by polymerizing, for example, a cyclic olefin monomer represented by Formula (3) shown below and a cyclic olefin monomer represented by formula (4) shown below through ring opening metathesis polymerization.

In Formula (3), R¹ to R⁴ and n each have the same definition as that in Formula (1).

The cyclic olefin monomer according to the present embodiment may have two or more structural units in which at least one of R¹ to R⁴ in the structural unit represented by Formula (3) is different from the rest.

In Formula (4), R⁵ to R⁸, X₁, and n each have the same definition as that in Formula (2).

The cyclic olefin monomer according to the present embodiment may have two or more structural units in which at least one of R⁵ to R⁸ in the structural unit represented by Formula (4) is different from the rest.

The catalyst used at the time of polymerizing the cyclic olefin polymer according to the present embodiment is not particularly limited as long as the catalyst is capable of performing ring opening metathesis polymerization on the cyclic olefin monomer, and examples thereof include an organic transition metal alkylidene complex catalyst such as molybdenum (Mo), tungsten (W), or ruthenium (Ru); and a ring opening metathesis catalyst obtained by combining an organic transition metal catalyst and a Lewis acid serving as a co-catalyst. Further, it is preferable to use an organic transition metal alkylidene complex catalyst such as molybdenum (Mo), tungsten (W), or ruthenium (Ru).

The size of the molecular weight can be adjusted by optionally setting these ratios.

The monomer concentration in the polymerization reaction is not particularly limited since the monomer concentration varies depending on the reactivity of the cyclic olefin monomer or the solubility in a polymerization solvent, but the concentration of the cyclic olefin monomer is, for example, in a range of 0.001 kg/kg to 3 kg/kg, preferably in a range of 0.01 kg/kg to 2 kg/kg, and more preferably in a range of 0.02 kg/kg to 1 kg/kg with respect to 1 kg of the solvent.

Further, the cyclic olefin polymer represented by Formulae (1) and (2) according to the present embodiment may be in the form in which a double bond in the main chain is hydrogenated (also referred to as hydrogenation). In this manner, further excellent heat melt fluidity can be exhibited by releasing restriction on the movement of a polymer chain using a double bond in the main chain, for example, lowering the glass transition temperature of the polymer and adjusting the temperature of the intersection between a storage modulus (G′) curve and a loss modulus (G″) curve which are measured using a rheometer described below. As the result, an underlayer film in which defects such as voids are further suppressed and which has excellent flatness and exhibits an excellent embedding property can be formed.

The catalyst for hydrogenating a double bond moiety in the main chain of the polymer obtained by the ring opening metathesis polymerization may be a homogeneous metal complex catalyst or a heterogeneous metal-supported catalyst as long as the catalyst is capable of carrying out hydrogenation. Among these, a heterogeneous metal-supported catalyst which can easily separate a catalyst is suitable, and preferred examples thereof include activated carbon-supported palladium, alumina-supported palladium, activated carbon-supported rhodium, alumina-supported rhodium, activated carbon-supported ruthenium, and alumina-supported ruthenium.

These solvents may be used alone or in combination of two or more kinds thereof. Further, it is preferable that a step which is suitable for productivity can be employed without carrying out a solvent substitution step by means of using the same kind of solvent as the solvent selected based on the polymerization reaction described above.

Further, the hydrogenation treatment of the olefin moiety in the main chain is not particularly limited. Hydrogenation treatment may be carried out to a polymer redissolved in a solvent, after the polymer is isolated by adding a poor solvent to a polymerization solution that contains the polymer before hydrogenation treatment. Further, hydrogenation treatment may be carried out using the above-described hydrogenation catalyst, without isolating the polymer from the polymerization solution.

Particularly, the method of obtaining a polymer from a polymer solution in a case of preferably using a heterogeneous metal-supported catalyst such as activated carbon rhodium or activated carbon ruthenium after the hydrogenation is not particularly limited, and examples thereof include a method of obtaining a polymer solution which does not contain a catalyst using a method of filtration, centrifugation, or decantation and discharging the reaction solution to a poor solvent being stirred; a method of precipitating a polymer using a steam stripping method of blowing steam into the reaction solution; and a method of evaporating and removing a solvent from the reaction solution through heating.

Further, in a case where the hydrogenation reaction is carried out using a heterogeneous metal-supported catalyst, the polymer can be obtained according to the above-described method after a synthetic solution is filtered and the metal-supported catalyst is separated by filtration. In order to obtain a polymer solution particularly free of a metal which is used in a semiconductor device manufacturing step, the polymer may be obtained according to the above-described method after a solution obtained by roughly removing a catalyst component is filtered. Particularly, it is suitable to perform microfiltration on the catalyst component, and the pore diameter of a filtration filter is preferably in a range of 10 μm to 0.05 μm, particularly preferably in a range of 10 μm to 0.10 μm, and still more preferably in a range of 5 μm to 0.10 μm.

In the cyclic olefin polymer according to the present embodiment, the weight-average molecular weight (Mw) thereof in terms of polystyrene which is measured by gel permeation chromatography (GPC) at a sample concentration of 3.0 to 9.0 mg/ml is preferably in a range of 1000 to 20000, more preferably in a range of 1500 to 19000, and still more preferably in a range of 2000 to 18000. In a case where the weight-average molecular weight (Mw) is set to be in the above-described range, further excellent heat melt fluidity can be exhibited at the time of heating the surface of the uneven structure of the substrate at a temperature of 200° C. to 250° C., which is applied in a typical semiconductor device manufacturing step, the heating thereof is performed in a baking step after the surface thereof is coated with the material for forming an underlayer film according to the present embodiment. As the result, an underlayer film in which defects such as voids are further suppressed and which has excellent flatness and exhibits an excellent embedding property can be formed.

The molecular weight distribution (Mw/Mn), which is a ratio between the weight-average molecular weight (Mw) and the number average molecular weight (Mn) in a case where the molecular weight (Mw) is in the above-described range, is preferably in a range of 1.3 to 5.0, more preferably in a range of 1.3 to 4.0, and still more preferably in a range of 1.3 to 3.0. In a case where the molecular weight distribution (Mw/Mn) is set to be in the above-described range, the melt unevenness with respect to the heating during the baking step can be further suppressed, and the resin is further uniformly melted. As the result, an underlayer film in which defects such as voids are further suppressed and which has excellent flatness and exhibits an excellent embedding property can be formed.

As a measure of showing the melt fluidity through the heating described above, for example, the temperature showing an intersection between a storage modulus (G′) curve and a loss modulus (G″) curve in measurement of the solid viscoelasticity of the cyclic olefin polymer or the material for forming an underlayer film according to the present embodiment can be used (see FIG. 1).

The intersection between the storage modulus (G′) curve and the loss modulus (G″) curve can be used as a measure of showing a change of rheology of a substance (also referred to as a resin). Typically, the substance in a temperature rising step up to the intersection shows characteristics as an elastic body, and the resin does not flow. Further, the substance shows characteristics as a viscous fluid by being heated to a higher temperature through the intersection, and thus the resin flows. In other words, in order to embed the uneven surface of the substrate in a further uniform state while suppressing defects such as voids, it is preferable that moderate fluidity is exhibited. In other words, in the cyclic olefin polymer or the material for forming an underlayer film according to the present embodiment, in a case where the intersection between the storage modulus (G′) curve and the loss modulus (G″) curve is preferably in a range of 40° C. to 200° C., more preferably in a range of 40° C. to 195° C., and still more preferably in a range of 40° C. to 190° C., the cyclic olefin polymer or the material for forming an underlayer film according to the present embodiment can exhibit moderate fluidity required to uniformly embed the uneven structure of the surface of the substrate under a heating condition of 200° C. to 250° C. which has been typically used in a semiconductor device manufacturing step.

The lower limit of the intersection between the storage modulus (G′) curve and the loss modulus (G″) curve is more preferably 80° C. or higher, still more preferably 90° C. or higher, and particularly preferably 100° C. or higher. Further, the upper limit of the intersection between the storage modulus (G′) curve and the loss modulus (G″) curve is preferably 200° C. or lower, more preferably 195° C. or higher, and particularly preferably 190° C. or lower.

Here, the solid viscoelasticity of the cyclic olefin polymer or the material for forming an underlayer film according to the present embodiment can be measured under conditions of a measurement temperature range of 30° C. to 300° C. (or in a range of 50° C. to 250° C.), a heating rate of 3° C./min, and a frequency of 1 Hz in a nitrogen atmosphere in a shear mode using a rheometer.

In a case where the intersection between the storage modulus (G′) curve and the loss modulus (G″) curve is less than or equal to the above-described upper limit, the cyclic olefin polymer or the material for forming an underlayer film according to the present embodiment shows the characteristics as a viscous fluid, the resin flows, and the uneven surface of the substrate can be embedded in a more uniform state while defects such as voids are further suppressed.

Further, in a case where the intersection between the storage modulus (G′) curve and the loss modulus (G″) curve is greater than or equal to the above-described lower limit, the fluidity of the cyclic olefin polymer or the material for forming an underlayer film according to the present embodiment can be suppressed. As the result, shrinkage in the uneven surface of the substrate can be further suppressed, and the uneven surface of the substrate can be embedded in a more uniform state while defects such as voids are further suppressed.

In addition, the amount of the volatile component in the cyclic olefin polymer according to the present embodiment which is measured using the following method 1 is preferably greater than or equal to 0.0% by mass and less than or equal to 1.0% by mass, more preferably greater than or equal to 0.0% by mass and less than or equal to 0.7% by mass, still more preferably greater than or equal to 0.0% by mass and less than or equal to 0.5% by mass, and particularly preferably greater than or equal to 0.0% by mass and less than or equal to 0.1% by mass.

In this manner, since generation of the volatile component (outgas) accompanied by decomposition of the polymer at the time of heating and melting can be suppressed, a resist underlayer film with further excellent flatness can be formed.

In other words, a resist underlayer film which is capable of suppressing intermixing of an intermediate layer provided as an upper layer with the material used as a resist layer and suppressing generation of voids or the like, and has an embedding property in a further excellent state and further excellent flatness can be formed.

Next, the obtained coating film is treated at 200° C. for 10 minutes. Subsequently, the coating film is immersed in at least one organic solvent selected from the group consisting of an alcohol-based solvent, an ether-based solvent, a ketone-based solvent, an amide-based solvent, an ester-based solvent, and a hydrocarbon-based solvent (preferably propylene glycol-1-monomethyl ether-2-acetate (PGMEA)) at 23° C. for 10 minutes and dried under conditions of 150° C. for 3 minutes so that a remaining solvent in the coating film is removed. Next, a thickness (β) of the coating film obtained by removing the remaining solvent is measured, and the residual film rate (=β/α×100) (%) is calculated.

Some or all hydrogen atoms on a ring of the alicyclic hydrocarbon and the aromatic hydrocarbon may be substituted with a linear or branched alkyl group having 1 to 5 carbon atoms.

Among these, from the viewpoint of the adaptability to the process or the like, at least one selected from the group consisting of an alcohol-based solvent and an ester-based solvent is preferable. Examples of the alcohol-based solvent include propylene glycol monomethyl ether (PGME) and propylene glycol monopropyl ether (PGPE) Examples of the ester-based solvent include propylene glycol-1-monomethyl ether-2-acetate (PGMEA). These solvents may be used alone or in the form of a mixture of two or more kinds thereof.

In a case where the residual film rate of the cyclic olefin polymer according to the present embodiment is greater than or equal to the lower limit, intermixing can be suppressed during the formation of an intermediate layer on the resist underlayer film. As the result, a laminate which has excellent adhesiveness between the intermediate layer and the resist underlayer film and excellent flatness can be realized.

Here, the residual film rate may be in the above-described range in a case where at least one organic solvent selected from the group consisting of an alcohol-based solvent, an ether-based solvent, a ketone-based solvent, an amide-based solvent, an ester-based solvent, and a hydrocarbon-based solvent is used as an organic solvent, and it is preferable that the residual film rate is in the above-described range in a case where propylene glycol-1-monomethyl ether-2-acetate (PGMEA) is used as an organic solvent.

The glass transition temperature of the cyclic olefin polymer according to the present embodiment based on the differential scanning calorimetry is preferably in a range of 40° C. to 220° C., more preferably in a range of 40° C. to 200° C., and still more preferably in a range of 40° C. to 180° C.

In a case where the glass transition temperature thereof is in the above-described range, the temperature of the intersection between the storage modulus (G′) curve and the loss modulus (G″) curve is easily adjusted to be in the above-described range.

Further, for example, a method of performing SEM observation on a sample obtained by embedding the uneven surface of the substrate through formation of a coating film according to a spin coating method and cutting out the cross section of the sample after being baked is used for evaluation of the flatness of the resist underlayer film. In this case, it is preferable that the following flatness (ΔFT) can be used as a measure of showing the degree of fluctuation of the atmospheric surface. First, ten heights from the bottoms of recesses to the atmospheric surface (a surface (α) described below) in the uneven structure of the substrate are measured, and the average value (H_av) is set as the film thickness. Next, based on the result obtained by measuring the maximum value (H_max) and the minimum value (H_min) among the film thicknesses in fluctuation, a value ([(H_max−H_min)/H_av]×100(%)) obtained by dividing a difference (H_max−H_min) between the maximum value and the minimum value by the average value of the film thicknesses is set as the measure of the flatness (ΔFT). Here, in a case where the substrate does not have an uneven structure, the “heights from the bottoms of recesses to the atmospheric surface” may be replaced by the “height from the surface of the substrate to the atmospheric surface”.

FIG. 2 are schematic views for describing a film thickness 4 of a resist underlayer film 2, a height 5 of an uneven structure 7, and an interval 6 between projections of the uneven structure 7 in a laminate 10 according to the embodiment of the present invention. As shown in FIG. 2, in a case where a substrate 1 has the uneven structure 7, the height from the bottom of a recess to a surface (α) 3 is set as a film thickness 4 of the resist underlayer film 2. Further, in a case where the substrate 1 does not have the uneven structure 7, the height from the surface of the substrate 1 to the surface (α) 3 is set as the film thickness 4 of the resist underlayer film 2.

The flatness (ΔFT) is preferably in a range of 0% to 5%, more preferably in a range of 0% to 3%, and still more preferably in a range of 0% to 1%. In this manner, the thickness of the resist layer can be made more uniform regardless of the presence of the intermediate layer, and a desired pattern in lithography can be obtained with excellent reproducibility.

Further, for example, a method of performing SEM observation on a sample obtained by embedding the uneven surface of the substrate through formation of a coating film according to a spin coating method and cutting out the cross section of the sample after being baked is used for evaluation of the difference in film thickness in an isolated or dense pattern of the resist underlayer film. In this case, in a switching portion of the isolated and dense pattern, as shown in FIG. 3-2, in a case where the width between projections (recess width) in the uneven structure of the substrate is set as a and the projection width is set as b, the ratio [a/(a+b)] of the width between projections to the pattern pitch width represented by a+b is set as α, and the α value, α₁, and α₂ for each of the pattern areas with different widths between projections and different projection widths on the same substrate are acquired. The switching portion of the isolated and dense pattern is obtained in a case where the absolute value of the difference between α1 and α2 is in a range of 0<|α1−α2|<1. In the difference in film thickness in the switching portion of the isolated and dense pattern, ten film thicknesses from the bottoms of recesses to the atmospheric surface in each of the pattern regions on the same substrate with different α values are measured, an average value H₁, an average value H₂, and an average value H₃ of H₁ and H₂ are respectively acquired, and a value (|H₁−H₂|/H₃×100(%)) obtained by dividing the absolute value |H₁−H₂| of the difference between the average film thicknesses from the bottoms of recesses to the atmospheric surface in two pattern regions by H₃ is set as the measure of the flatness (ΔFT).

In FIG. 3-2, “a₁/(a₁+b₁)=α₁” and “a₂/(a₂+b₂)=α₂” are satisfied. H₁ and H₂ each indicate the average film thickness from the bottoms of recesses to the atmospheric surface in the regions of α₁ and α₂, and “|H₁−H₂|/H₃×100(%)=ΔFT” is satisfied.

The flatness (ΔFT) is preferably in a range of 0% to 5%, more preferably in a range of 0% to 3%, and still more preferably in a range of 0% to 1%. In this manner, the thickness of the resist layer can be made more uniform regardless of the presence of the intermediate layer, and a desired pattern in lithography can be obtained with excellent reproducibility.

In an ArF photolithography step of transferring a pattern of a photomask using an ArF excimer laser having a wavelength of 193 nm to a layer formed of a resist material formed over the underlayer film, light having passed through the underlayer film from the resist layer is reflected on the surface of the semiconductor substrate and is incident on the resist layer on the upper side from the underlayer film again. In other words, the roughness of the pattern may deteriorate because optical interference occurs due to the influence of a stationary wave and this result in non-uniform concentration of an acid generated inside the resist. Further, in a case where a substrate having a plurality of trenches particularly with aspect ratios different from one another, reflection of light causes irregular reflection on a stepped portion, and the irregular-reflected light is incident on the resist layer from the underlayer film again. Therefore, a phenomenon in which the transfer accuracy deteriorates due to the acid generated by the light which has been incident inside the resist layer that should be an unexposed portion occurs.

In order to prevent deterioration of pattern roughness or deterioration of transfer accuracy due to a stationary wave or irregular reflection on the resist layer from the underlayer film, the underlayer film is required to have a function as an anti-reflection film. Practically, it is considered that the reflectivity into the resist film from the underlayer film needs to be suppressed to less than or equal to 1%.

As a specific method of allowing the underlayer film to exhibit the function as an anti-reflection film, a method of controlling an optical constant of the material for forming an underlayer film has been known.

The reflectivity to the resist film from the underlayer film can be set to less than or equal to 1% by controlling a refractive index (n value) of the cyclic olefin polymer or the material for forming an underlayer film according to the present embodiment at a wavelength of 193 nm which is measured using the following method 2 and an extinction coefficient (k value) of the cyclic olefin polymer or the material for forming an underlayer film according to the present embodiment which is measured using the following method 3 such that the n value and the k value are preferably set to be in a range of 1.5 to 2.0 and 0.0001 to 0.5 respectively, more preferably set to be in a range of 1.55 to 1.95 and 0.0001 to 0.4 respectively, and still more preferably set to be in a range of 1.6 to 1.9 and 0.0001 to 0.3 respectively. Further, from the viewpoint of exhibiting the anti-reflection performance, it is preferable that the anti-reflection film has a flat shape. From the viewpoint of forming an anti-reflection film it is preferable that the present embodiment is employed since the surface of the base film can be made flat.

Method 2: A coating film which is formed of the cyclic olefin polymer or the material for forming an underlayer film and has a thickness of 250 nm is formed on a silicon wafer, and the refractive index (n value) of the obtained coating film at a wavelength of 193 nm is set as the refractive index (n value) of the material for forming an underlayer film.

Method 3: A coating film which is formed of the cyclic olefin polymer or the material for forming an underlayer film and has a thickness of 250 nm is formed on a silicon wafer, and the extinction coefficient (k value) of the obtained coating film is set as the extinction coefficient (k value) of the cyclic olefin polymer or the material for forming an underlayer film.

Further, the average value Hay (the film thicknesses of the resist underlayer film at ten optional sites of the surface (α) of the resist underlayer film on a side opposite to the substrate are measured, and the average value of these is set as Hay) of the film thicknesses (the distances from the upper portion of the substrate to the surface of the underlayer film at several optional sites are measured in a case where the substrate that does not have an uneven structure is used, and the distances from the bottoms of recesses of the substrate to the surface of the underlayer film are measured in a case where a substrate having an uneven structure is used) of the underlayer film used here is preferably in a range of 5 to 1000 nm, more preferably in a range of 5 to 800 nm, still more preferably in a range of 5 to 600 nm, even still more preferably in a range of 5 to 500 nm, even still more preferably in a range of 7 to 450 nm, and even still more preferably in a range of 10 to 400 nm. Further, the lower limit of the average value H_av of the film thicknesses of the resist underlayer film is preferably 5 nm or greater, more preferably 7 nm or greater, and still more preferably 10 nm or greater, and the upper limit thereof is preferably 1000 nm or less, more preferably 800 nm or less, still more preferably 600 nm or less, even still more preferably 500 nm or less, even still more preferably 450 nm or less, and even still more preferably 400 nm or less. In a case where the n value and the k value are respectively in the above-described range and the thickness of the underlayer film is in the above-described range, a processed substrate which is free of roughness in the pattern of the photomask and is transferred with high accuracy in the ArF photolithography step can be obtained.

Some or all hydrogen atoms on a ring of the alicyclic hydrocarbon and the aromatic hydrocarbon may be substituted with a linear or branched alkyl group having 1 to 5 carbon atoms.

Among these, the solvent is selected in consideration of the volatilization rate of the solvent at the time of application, the adaptability to the process, and the productivity, and it is preferable that an oxygen-containing solvent such as an alcohol-based solvent, a chain-like ketone-based solvent, a cyclic ether-based solvent, or an ester-based solvent is selected. The material for forming an underlayer film according to the present embodiment may contain one or two or more kinds of solvents.

Further, the concentration of the cyclic olefin polymer in the varnish-like material for forming an underlayer film according to the present embodiment is preferably in a range of 0.01% to 50.0% by mass, more preferably in a range of 0.1% to 45.0% by mass, and still more preferably in a range of 1.0% to 40.0% by mass.

Meanwhile, in a case where a crosslinking agent is used, the influence of reaction shrinkage at the time of curing may become significant. For example, in a case where the pattern of unevenness is irregular, the amount of the crosslinking agent is extremely large, and the distance between projections is long, the influence of the shrinkage cannot be ignored in some cases. Accordingly, the flatness may be degraded. Therefore, it is preferable that the content of the crosslinking agent in the material for forming an underlayer film according to the present embodiment is small.

Further, these crosslinking agents may be used alone or in combination of two or more kinds thereof.

Next, the varnish-like material for forming an underlayer film which has been prepared using the above-described method is filtered by being allowed to pass through a filter. In this manner, polymer insoluble, gels, or foreign matter can be removed from the varnish-like material for forming an underlayer film, and a uniform layer as an underlayer film can be formed between the resist film layer and the surface of the substrate.

Examples of the material of the filter include organic materials such as polytetrafluoroethylene (PTFE), polypropylene (PP), polyether sulfone (PES), and cellulose; and inorganic materials such as glass fibers and metals, and the material can be selected in consideration of the varnish characteristics and the process adaptability as long as the material does not affect the function as the underlayer film.

Further, examples of the method of sending the varnish to the filter include a method of using a pressure difference and a method of sending the varnish to the filter using mechanical drive through a screw or the like.

It is preferable that the laminate has a structure in which the substrate (a) is in contact with the resist underlayer film (b).

Here, the resist underlayer film (b) and the method of producing the resist underlayer film are the same as the resist underlayer film and the method of producing the resist underlayer film according to the present embodiment, and thus the description thereof will not be repeated.

Here, the above-described height indicates the height 5 of the uneven structure 7 shown in FIG. 2. For example, optional ten heights 5 of the uneven structure 7 are measured, and the average value of these heights can be employed as the height.

Further, the interval between projections in the uneven structure is preferably greater than or equal to 1 nm and less than or equal to 10 mm. The lower limit of the interval between projections in the uneven structure is more preferably 3 nm or greater, more preferably 5 nm or greater, and particularly preferably 10 nm or greater.

Further, the upper limit of the interval between projections in the uneven structure is more preferably 5 mm or less, more preferably 1 mm or less, and particularly preferably 0.5 mm or less.

From the viewpoint that the effects of the resist underlayer film (b) tend to be significantly exhibited, it is preferable that the substrate (a) has the above-described uneven structure.

The thickness of the substrate (a) is preferably in a range of 0.01 to 10000 μm. The lower limit of the thickness of the substrate (a) is more preferably 0.03 μm or greater, still more preferably 0.05 μm or greater, and particularly preferably 0.10 μm or greater.

In this manner, the thickness of the resist layer can be made more uniform regardless of the presence of the intermediate layer, and a desired pattern in lithography can be obtained with excellent reproducibility.

<Pattern Formation Method>

A pattern formation method according to the present embodiment includes a step of forming a resist pattern on an upper surface side of the resist underlayer film according to the present embodiment (hereinafter, also referred to as a “resist pattern forming step”); and a step of sequentially etching the resist underlayer film and the substrate using the resist pattern as a mask (hereinafter, also referred to as an “etching step”).

Further, the pattern formation method according to the present embodiment may be performed by forming an intermediate layer on an upper surface side of the resist underlayer film to form a resist pattern on an upper surface side of the intermediate layer in the resist pattern forming step and etching the intermediate layer in the etching step.

According to the pattern formation method according to the present embodiment, an excellent pattern can be formed because the resist underlayer film according to the present embodiment which has sufficient optical characteristics, etching resistance, excellent flatness, and a suppressed generation of volatile components is used.

Hereinafter, each step will be described, but the present invention is not limited thereto.

[Resist Pattern Forming Step]

In the present step, a resist pattern is formed on the upper surface side of the resist underlayer film. An intermediate layer is formed on the upper surface side of the resist underlayer film, and the resist pattern is formed on the upper surface side of this intermediate layer.

The intermediate layer indicates a layer that compensates for the functions of the resist underlayer film and/or the resist film or has these functions for imparting the functions that the resist underlayer film and/or the resist film does not have in the formation of the resist pattern or the like. For example, in a case where an anti-reflection film (also referred to as an anti-reflection layer) is formed as an intermediate layer, the intermediate layer can compensate for the anti-reflection function of the resist underlayer film. Further, in a case where a hard mask layer is formed as an intermediate layer, the influence on the resist underlayer film in case of using an alkali developer during a developing step is suppressed and/or the insufficient etching resistance of the resist pattern formation layer in case of etching the substrate formed of silicon, aluminum, nickel, and the like of the lower layer after etching the underlayer film according to the present embodiment can be compensated.

Further, the intermediate layer formed on the underlayer film according to the present embodiment may include one or both of the anti-reflection layer and the hard mask layer, and the layers may be configured such that the anti-reflection layer or the hard mask layer is formed directly on the underlayer film according to the present embodiment. The layer configuration is suitably selected in consideration of the characteristics of the resist material and the processed substrate material and the productivity.

The intermediate layer can be formed of an organic compound or an inorganic oxide. Examples of the organic compound include DUV-42, DUV-44, ARC-28, and ARC-29 (all manufactured by Brewer Science, Inc.); and AR-3 and AR-19 (both manufactured by Rohm and Haas Company). Further, as the inorganic oxide, NFC SOG Series (manufactured by JSR Corporation), and polysiloxane, titanium oxide, alumina oxide, and tungsten formed using a CVD method oxide can be used.

The method of forming the intermediate layer is not particularly limited, and examples thereof include a coating method and a CVD method. Among these, a coating method is preferable. In a case of using the coating method, the intermediate layer can be continuously formed after formation of the resist underlayer film.

Further, the film thickness of the intermediate layer is not particularly limited and can be appropriately selected depending on the function required for the intermediate layer, and the film thickness thereof is preferably in a range of 1 nm to 5 μm, more preferably in a range of 5 nm to 3 μm, and still more preferably in a range of 10 nm to 0.3 μm.

Examples of the method of forming the resist pattern on the upper surface side of the resist underlayer film or the intermediate layer include a method of using photolithography. This method will be described in detail layer, and the present invention is not limited thereto.

The method of using photolithography includes a step of forming a resist film on the upper surface side of the resist underlayer film using a resist composition or the like (hereinafter, also referred to as a “resist film forming step”); a step of exposing the resist film (hereinafter, also referred to as an “exposing step”), and a step of developing the exposed resist film (hereinafter, also referred to as a “developing step”).

(Resist Film Forming Step)

In the present step, the resist film is formed on the upper surface side of the resist underlayer film.

Specifically, the resist film is formed by coating the surface with the resist composition such that the obtained resist film has a predetermined film thickness and allowing the solvent in the coating film to volatilize by performing pre-baking.

Examples of the resist composition include a positive type or negative type chemically amplified resist composition containing a photoacid generator; a positive type resist composition formed of an alkali-soluble resin and a quinone diazide-based photosensitive agent; and a negative type resist composition formed of an alkali-soluble resin and a crosslinking agent.

The solid content concentration of the resist composition is preferably in a range of 0.1% by mass to 50% by mass, more preferably in a range of 0.5% by mass to 50% by mass, and still more preferably in a range of 1.0% by mass to 50% by mass, and the solid content concentration thereof can be selected to be in an appropriate range in consideration of the target film thickness and the productivity.

Further, it is preferable that the resist composition is prepared by being filtered through a filter having a pore diameter of approximately 0.1 μm. Further, in this step, a commercially available resist composition can be used as it is. The method of coating the surface with the resist composition is not particularly limited and can be performed using a spin coating method, a cast coating method, or a roll coating method.

Further, the pre-baking temperature is appropriately selected depending on the kind of the resist composition to be used, but is preferably in a range of 30° C. to 200° C. and more preferably in a range of 50° C. to 150° C.

(Exposing Step)

In the present step, the resist film formed in the resist film forming step is exposed. The resist film is exposed through, for example, a predetermined mask pattern and liquid immersion as necessary.

The exposure light is appropriately selected from electromagnetic waves such as visible light, ultraviolet rays, deep ultraviolet rays, X rays, and γ rays; and particle beams such as electron beams, molecular beams, ion beams, and a rays depending on the kind of the photoacid generator used in the resist composition. In addition, deep ultraviolet rays are preferable; KrF excimer laser light (248 nm), ArF excimer laser light (193 nm), F2 excimer laser light (wavelength of 157 nm), Kr2 excimer laser light (wavelength of 147 nm), ArKr excimer laser light (wavelength of 134 nm), or extreme ultraviolet rays (wavelength of 13 nm and the like) are more preferable, and ArF excimer laser light is still more preferable.

After the exposure, post-baking can be performed in order to improve the resolution, the pattern profile, and the developability of the resist pattern to be formed.

The post-baking temperature is appropriately adjusted depending on the kind of the resist composition to be used, but is preferably in a range of 50° C. to 200° C. and more preferably in a range of 70° C. to 150° C.

(Developing Step)

In the present step, the resist film exposed in the exposing step is developed.

The developer used in the development is appropriately selected depending on the kind of the resist composition to be used. In a case of alkali development, examples of the developer include an alkaline aqueous solution such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium silicate, sodium metasilicate, ammonia, ethylamine, n-propylamine, diethylamine, di-n-propylamine, trimethylamine, methyl diethylamine, dimethyl ethanolamine, triethanolamine, tetramethyl ammonium hydroxide, tetraethyl ammonium hydroxide, pyrrole, piperidine, choline, 1,8-diazabicyclo[5.4.0]-7-undecene, or 1,5-diazabicyclo[4.3.0]-5-nonene. Further, in a case where the intermediate layer is formed by performing the intermediate layer forming step, the influence on the resist underlayer film of any of these alkaline aqueous solutions can be suppressed.

An appropriate amount of a surfactant or a water-soluble organic solvent such as methanol or ethanol can be added to these alkaline aqueous solutions.

Further, a developer containing an organic solvent can be used as the developer. Examples of the organic solvent include esters, ketones, ethers, alcohols, amides, and hydrocarbons. The solvent used in the organic solvent development is appropriately selected depending on the characteristics of the resist underlayer film.

After the development using the developer, a predetermined resist pattern is formed by performing washing and drying on the resist film.

Further, as the method of performing the resist pattern forming step, a method of using a nanoimprint method or a method of using a self-assembled composition can be used in addition to the method of using photolithography described above.

[Etching Step]

In this step, the resist underlayer film and the substrate are sequentially etched using the resist pattern as a mask. In this manner, the pattern is formed on the substrate. Further, in a case of forming an intermediate layer, the intermediate layer is also etched.

The above-described etching may be dry etching or wet etching. The dry etching can be performed using a known dry etching device. In addition, the source gas at the time of dry etching is not particularly limited because the source gas depends on the elemental composition of the material to be etched, and examples of the source gas include gas containing an oxygen element such as O₂, CO, or CO₂; inert gas such as H_e, N₂, or Ar; chlorine-based gas such as Cl₂ or BCl₃; fluorine-based gas such as CHF₃ or CF₄; and gas such as H₂ or NH₃. Further, these gases can be used by being mixed.

[Method of Removing Underlayer Film Material after Formation of Substrate Pattern]

In the present step, the resist underlayer film which becomes unnecessary is removed after the resist pattern is transferred to the substrate and formed thereon in the etching step.

The removal method may be a dry method or a wet method using a solvent or the like and is suitably selected in consideration of the physical properties of the material and the process adaptability. Further, a combination of the dry method and the wet method may be used as the removal method.

In a case of the dry method, a dry etching device used in the etching step can be used. Accordingly, the dry method is preferable used from the viewpoint of the productivity since there is no need to change the production line at the time of transition from the etching step to the step of removing the underlayer film material.

In the step of removing the underlayer film material, the source gas at the time of using a dry etching device is suitably selected depending on the elemental composition of the material to be etched, and examples of the source gas include gas containing an oxygen element such as O₂, CO, or CO₂; inert gas such as H_e, N₂, or Ar; chlorine-based gas such as Cl₂ or BCl₃; fluorine-based gas such as CHF₃ or CF₄; and gas such as H₂ or NH₃. The gas source is suitably selected depending on the substrate material or the low dielectric material applied to the surface of the substrate. Further, these gases can be used in the form of a mixture of two or more kinds thereof.

[Second Invention]

Hereinafter, an embodiment according to the second invention will be described.

<Material for Forming Underlayer Film>

A material for forming an underlayer film according to the present embodiment is a material for forming an underlayer film which is used to form a resist underlayer film used in a multi-layer resist process. Further, the material for forming an underlayer film contains a cyclic olefin polymer, and the residual film rate of the material for forming an underlayer film which is measured using the following method 4 is greater than or equal to 50% and less than or equal to 100% and preferably greater than or equal to 60% and less than or equal to 100%. The lower limit of the residual film rate of the material for forming an underlayer film is more preferably 70% or greater. In addition, the upper limit of the residual film rate of the material for forming an underlayer film is more preferably 99% or less and still more preferably 98% or less. As described above, in a case where the residual film rate is extremely low, defects caused by mixing with the intermediate layer may occur. Meanwhile, in a case where the residual film rate is slightly lower than 100%, a moderate degree of entanglement of polymers forming the intermediate layer and the base film occurs so that the peeling strength is increased in some cases.

Method 4: A coating film which is formed of the material for forming an underlayer film according to the present embodiment and has a thickness (a) of greater than or equal to 200 nm and less than or equal to 500 nm is formed on a silicon wafer. Next, the obtained coating film is treated at 200° C. for 10 minutes. Next, the coating film is immersed in propylene glycol-1-monomethyl ether-2-acetate at 23° C. for 10 minutes and dried under conditions of 150° C. for 3 minutes so that a remaining solvent in the coating film is removed. Next, the thickness (β) of the coating film obtained by removing the remaining solvent is measured, and the residual film rate (=β/α×100) (%) is calculated.

Further, the material for forming an underlayer film according to the present embodiment is a material for forming an underlayer film which is used to form a resist underlayer film used in a multi-layer resist process. Further, the material for forming an underlayer film is a material of a film containing a cyclic olefin polymer, the cyclic olefin polymer is soluble in an organic solvent at any concentration of at least greater than or equal to 0.01% by mass and less than or equal to 50% by mass, and a residual film rate of the cyclic olefin polymer in the film which is measured using the following method 4 is greater than or equal to 50% and less than or equal to 100% and preferably greater than or equal to 60% and less than or equal to 100%. The lower limit of the residual film rate of the cyclic olefin polymer is more preferably 70% or greater. In addition, the upper limit of the residual film rate of the cyclic olefin polymer is more preferably 99% or less and still more preferably 98% or less. As described above, in a case where the residual film rate is extremely low, defects caused by mixing with the intermediate layer may occur. Meanwhile, in a case where the residual film rate is slightly lower than 100%, a moderate degree of entanglement of polymers forming the intermediate layer and the base film occurs so that the peeling strength is increased in some cases.

Method 4: A coating film which is formed of the cyclic olefin polymer according to the present embodiment and has a thickness (c) of greater than or equal to 200 nm and less than or equal to 500 nm is formed on a silicon wafer. Next, the obtained coating film is treated at 200° C. for 10 minutes. Next, the coating film is immersed in propylene glycol-1-monomethyl ether-2-acetate at 23° C. for 10 minutes and dried under conditions of 150° C. for 3 minutes so that a remaining solvent in the coating film is removed. Next, the thickness (β) of the coating film obtained by removing the remaining solvent is measured, and the residual film rate (=β/α×100) (%) is calculated.

Here, as a condition for treating the peeled film at a high temperature, it is more preferable that the peeled film is treated at 200° C. for 30 minutes.

The residual film rate according to the method 4 indicates the solubility of the film in a solvent. There is a tendency that the film is unlikely to be dissolved in a solvent as the value increases.

As described above, in a case where a circuit diagram is drawn using the line width less than or equal to the wavelength of exposure light, a method of forming a plurality of uneven layers and combining the layers has been known. In order to realize such a mode, a method of forming an intermediate layer on a resist underlayer film for the purpose of smoothing the uneven layers and forming a new resist layer thereon can be exemplified.

According to the examination conducted by the present inventors, for example, in a case where this intermediate layer is formed according to a spin coating method or the like, a wrong choice of a solvent may lead to intermixing of the resist underlayer film with the intermediate film. As the result, it was found that the interface strength between the underlayer film and the intermediate layer may be degraded or the smoothness of the underlayer film may be lost.

The present inventors repeatedly conducted examination in order to solve the above-described problems. As the result, it was found that occurrence of intermixing of the resist underlayer film with the intermediate layer can be suppressed in a case where the resist underlayer film has a low affinity for the solvent used for formation of the intermediate layer.

The present inventors repeatedly conducted examination based on the above-described knowledge. As the result, it was found for the first time that dissolution of the resist underlayer film or mixing of the resist underlayer film with the intermediate layer more than necessary can be effectively suppressed by using the material for forming an underlayer film or the cyclic olefin polymer whose residual film rate at the time of being immersed in propylene glycol-1-monomethyl ether-2-acetate, which is measured according to the method 4, is in the above-described range.

In other words, in a case where the residual film rate of the material for forming an underlayer film or the cyclic olefin polymer according to the present embodiment which is measured according to the method 4 is greater than or equal to the above-described lower limit, dissolution of the resist underlayer film or mixing of the resist underlayer film with the intermediate layer more than necessary can be suppressed at the time of forming the intermediate layer on the resist underlayer film. As the result, a laminate having excellent adhesiveness between the intermediate layer and the resist underlayer film and excellent flatness can be realized.

The cyclic olefin polymer used in the second invention is not particularly limited as long as the polymer is dissolved in an organic solvent in a temperature range of room temperature to 50° C. and preferably at room temperature. As the organic solvent, a solvent selected from the group consisting of an alcohol-based solvent, an ether-based solvent, a ketone-based solvent, an amide-based solvent, an ester-based solvent, and a cyclic hydrocarbon-based solvent is preferable. Among these, an alcohol-based solvent, an ether-based solvent, a ketone-based solvent, an amide-based solvent, or an ester-based solvent is more preferable, and an ether-based solvent, a ketone-based solvent, an amide-based solvent, or an ester-based solvent is still more preferable. A solvent having a polyether monoester structure is particularly preferable.

More specific preferred examples of the cyclic olefin polymer of the second invention include a cyclic olefin polymer having a norbornane skeleton or a tetracyclododecane skeleton. Further, it is preferable that the cyclic olefin polymer has a substituent having heteroatoms contained in the above-described organic solvent. Preferred examples of the substituent having heteroatoms include an alkoxy group, an aryloxy group, an alkoxyalkyl group, an aryloxyalkyl group, an alkoxycarbonyl group, a dialkylaminocarbonyl group, an aryloxycarbonyl group, an alkylarylaminocarbonyl group, an alkoxycarbonylalkyl group, an alkoxycarbonylaryl group, an aryloxycarbonylalkyl group, an alkoxyalkyloxycarbonyl group, and an alkoxycarbonylalkyloxycarbonyl group. As the substituent, the above-described ester groups are particularly preferable.

Other specific preferred examples of the cyclic olefin polymer used in the second invention include a cyclic olefin polymer having the structural unit [A] and the structural unit [B] disclosed in the first invention. The preferable conditions such as the proportions of these structural units are the same as those disclosed in the first invention.

A known method can be used as the method of forming a film using the material for forming an underlayer film according to the present embodiment. Specific preferred examples thereof include a spin coating method. As the solvent that forms a polymer solution used for spin coating, the above-described solvent for spin coating can be exemplified. Particularly preferred examples thereof include polyether ester or polyether such as the above-described PGMEA, ketone, alcohol, and ester. In consideration of the solubility or the drying step after film formation, a mode of containing a solvent having a cyclic structure is preferable in some cases. Specifically, a cyclic ketone compound such as cycloalkanone is exemplified, and cyclohexanone is preferable.

It is desirable that the material for forming an underlayer film according to the present embodiment is treated at a high temperature for a predetermined time. Specifically, a temperature range of 100° C. to 400° C. can be exemplified as the temperature condition. The lower limit of the temperature is preferably 150° C. or higher and more preferably 180° C. or higher. Meanwhile, the upper limit of the temperature is preferably 300° C. or lower and more preferably 250° C. or lower. Based on this reason, the present inventors speculated as follows.

According to the examination conducted by the present inventors, the film formed using the cyclic olefin polymer containing a polar group according to the present embodiment is in the form in which a relatively uniform change in polarity occurs in the entire heated portion by the heat treatment. It is considered that the solubility in a solvent is greatly changed, in other words, the film is unlikely to be dissolved in the organic solvent due to the change of the polarity. According to the present inventors, it is considered that the above-described change may be caused by the change of properties of the polar group in the cyclic olefin polymer according to the present embodiment. The possibility that the change is caused by a pseudo-crosslinked structure or a crosslinked structure being employed. For example, the configuration having the structure represented by Formula (2) is a preferable aspect and the effects are high. Hereinafter, the description will be provided in more detail.

In order to change the polarity of the film containing the cyclic olefin polymer according to the present embodiment, it is important that the polymer contains one or two repeating structural units [B] represented by Formula (2) in some cases. In a case where the repeating structural unit [B] represented by Formula (2) is heated, this causes cleavage of an ether group and a thioether group so that the polarity of a molecule can be changed.

As another aspect, in a case where at least one of R¹ to R⁸ contains an alkoxycarbonyl group, an alkoxycarbonylalkyl group, an alkoxycarbonylaryl group, or an alkoxycarbonylalkyloxycarbonyl group and preferably one or more of alkoxycarbonyl groups in which tertiary carbons are bonded to form an ester group, alkoxycarbonylalkyl groups, alkoxycarbonylaryl groups, alkoxycarbonylalkyloxycarbonyl groups, or alkoxyalkyloxycarbonyl groups, generation of a carboxyl group due to heating can be expected to be led to a large change in polarity of a molecule.

Since the aspect of the present invention has such characteristics, as described above, it is considered that a sufficiently high intermixing resistance effect can be exhibited even in a case where the content of the crosslinking agent is decreased.

The material for forming an underlayer film according to the present embodiment is a material for forming a layer disposed between an intermediate layer and a substrate (preferably a substrate having an uneven structure) in a step of manufacturing a semiconductor device. The layer disposed between the intermediate layer and the substrate is referred to as a resist underlayer film based on a resist layer formed of a resist material that typically transfers a mask pattern in a photolithography process. The surface of the substrate which comes into contact with the resist underlayer film may be in a state in which a coating film is formed of a low dielectric material, such as a silica (SiO₂) film, a SiCN film, a SiOC film obtained by doping silica (SiO₂) with carbon (C), a methylsiloxane-based organic film (SOG), or a silica insulating film in which minute holes having a size of several nanometers or less are uniformly distributed.

The intermediate layer indicates a layer that compensates for the functions of the resist underlayer film and/or the resist film or has these functions for imparting the functions that the resist underlayer film and/or the resist film does not have in the formation of the resist pattern or the like. For example, in a case where an anti-reflection film (also referred to as an anti-reflection layer) is formed as an intermediate layer, the intermediate layer can compensate for the anti-reflection function of the resist underlayer film. Further, in a case where a hard mask layer is formed as an intermediate layer, the influence on the resist underlayer film in case of using an alkali developer during a developing step is suppressed and/or the insufficient etching resistance of the resist pattern formation layer at the time of etching the substrate formed of silicon, aluminum, nickel, and the like of the lower layer after etching the underlayer film according to the present embodiment can be compensated.

Further, the intermediate layer formed on the underlayer film according to the present embodiment may include one or both of the anti-reflection layer and the hard mask layer, and the layers may be configured such that the anti-reflection layer or the hard mask layer is formed directly on the underlayer film according to the present embodiment. The layer configuration is suitably selected in consideration of the characteristics of the resist material and the processed substrate material and the productivity.

The intermediate layer can be formed of an organic compound or an inorganic oxide. Examples of the organic compound include DUV-42, DUV-44, ARC-28, and ARC-29 (all manufactured by Brewer Science, Inc.); and AR-3 and AR-19 (both manufactured by Rohm and Haas Company). Further, as the inorganic oxide, NFC SOG Series (manufactured by JSR Corporation), and polysiloxane, titanium oxide, alumina oxide, and tungsten formed using a CVD method oxide can be used.

As the method of forming the intermediate layer, a coating method is preferable. In a case of using the coating method, the intermediate layer can be continuously formed after formation of the resist underlayer film.

As the solvent used for forming the intermediate layer according to the coating method, those exemplified as the solvents for a spin coating solution are preferable. Among these, polyether or polyether ester such as PGMEA is preferable.

Further, the film thickness of the intermediate layer is not particularly limited and can be appropriately selected depending on the function required for the intermediate layer, and the film thickness thereof is preferably in a range of 1 nm to 5 μm, more preferably in a range of 5 nm to 3 μm, and still more preferably in a range of 10 nm to 0.3 μm.

As a preferable cyclic olefin polymer related to the material for forming an underlayer film according to the present embodiment, the same polymer as the cyclic olefin polymer according to the first invention as described above can be used.

Therefore, detailed description will not be provided.

The resist underlayer film, the method of forming a resist underlayer film, and the pattern formation method according to the present embodiment are based on the resist underlayer film, the method of forming a resist underlayer film, and the pattern formation method according to the first invention. Therefore, detailed description will not be provided.

Hereinbefore, the embodiments of each of the inventions have been described, but these are merely examples of the present invention and various other configurations can be employed.

Further, the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like for achieving the purpose of the present invention are included in the present invention.

Further, the above-described present inventions can be combined as long as the contents do not contradict each other.

[Weight-Average Molecular Weight (Mw) and Molecular Weight Distribution (Mw/Mn)]

The weight-average molecular weight (Mw) and the number average molecular weight (Mn) of the polymer dissolved in tetrahydrofuran (THF) or trifluorotoluene (TFT) were measured using gel permeation chromatography (GPC) under the following conditions and calculated by calibrating the molecular weight based on polystyrene standards.

The glass transition temperature was measured by heating a measurement sample at a heating rate of 10°/C in a nitrogen atmosphere using DSC-50 (manufactured by Shimadzu Corporation).

[Method of Evaluating Volatile Component]

A THF solution of a polymer with a concentration of 20% by mass was weighed using an aluminum plate having a diameter of 5 mm such that the weight thereof was adjusted to 30 mg to 50 mg, and baked at 200° C. for 3 minutes in a nitrogen flow to remove THF. Next, the resultant was cooled to room temperature, and the weight thereof (W₀) was measured. Using a sample in a state in which a resin was solidified, the sample was heated to 30° C. to 300° C. at a heating rate of 10° C./min using TGA-60 (manufactured by Shimadzu Corporation) in a nitrogen atmosphere, and the weight thereof was continuously measured along with an increase in temperature to obtain the temperature vs. weight chart. Here, a weight reduction amount (W₁) in a temperature range of 100° C. to 250° C. was read from the chart, and the amount of volatile components was calculated based on the following equation.

Amount of volatile components (% by mass)=W₁/W₀×100

[Measurement of Solid Viscoelasticity]

The solid viscoelasticity was measured under conditions of a measurement temperature range of 30° C. to 300° C., a heating rate of 3° C./min, and a frequency of 1 Hz in a nitrogen atmosphere in a shear mode using MCR302 (rheometer) (manufactured by Anton Paar GmbH). More specifically, the measurement was carried out according to the following method.

First, white powder (10 mg) of the cyclic olefin polymer according to the present embodiment was placed in the center of a parallel disk having a diameter of 8 mm which had been heated to 230° C. Next, the powder was interposed using the disk, melted in a nitrogen atmosphere, and cooled to 30° C.

Thereafter, the sample was heated to 300° C. at the above-described heating rate and a frequency of 1 Hz in a shear mode.

Next, the obtained coating film was treated at 200° C. for 10 minutes or 30 minutes. After the sample was cooled to room temperature, the coating film was cut in a size of 20 mm×10 mm. This film was immersed in an organic solvent (propylene glycol-1-monomethyl ether-2-acetate (PGMEA), propylene glycol monomethyl ether (PGME), or a mixed solvent of PGME and PGMEA at a mass ratio (PGME/PGMEA) of 7/3) at 23° C. for 10 minutes and dried under conditions of 150° C. for 3 minutes so that the residual solvent in the coating film was removed. Next, the thickness (β) of the coating film from which the residual solvent had been removed was measured, and the residual film rate (=β/α×100) (%) was calculated.

Ten heights from the bottoms of recesses to the atmospheric surface in an area with a projection width of 40 nm and a width between projections of 120 nm from the cross section of the substrate A whose embedding property was evaluated were measured, and the average value thereof was set as H_av. Next, the flatness showing the index of the flatness was calculated using the following equation based on each of the maximum height (H_max) and the minimum height (H_min) from the ten measured heights.

Flatness(ΔFT)=[(H_max−H_min)/H_av]×100(%)

Further, ten heights from the bottoms of recesses to the atmospheric surface in each pattern region of an area having a₁ of 900 μm, b₁ of 900 μm, a₂ of 40 nm, and b₂ of 120 nm from the cross section of the substrate B whose embedding property was evaluated were measured, and the average value thereof was set as Hay, each of the average value H₁ (a₁ of 900 μm and b₁ of 900 μm), the average value H₂ (a₂ of 40 nm and b₂ of 120 nm), and the average value H₃ of H₁ and H₂ was acquired, and the flatness showing the index of the flatness was calculated using the following equation.

Based on the measurement results, the refractive indices (n value) and the extinction coefficients (k value) at 193 nm were calculated, and the n value and the k value were respectively acquired from the three average values.

Here, the measurement sample was prepared according to the following method.

A solution obtained by dissolving the cyclic olefin polymer according to the present embodiment in a PGMEA at a concentration of 10% by mass was prepared, and a 4 inch silicon wafer was spin-coated with the obtained solution. Next, the resulting sample was baked at 200° C. for 3 minutes in a nitrogen atmosphere. Subsequently, the sample was cooled to room temperature and cut in a size of 20 mm×20 mm, thereby obtaining a sample for measurement.

[Evaluation of Plasma Etching Characteristics]

A parallel plate type plasma treatment device RIH1515Z (manufactured by ULVAC, Inc.) was used. First, the plasma etching treatment was performed by placing a sample in a chamber, reducing the pressure inside the chamber to 1 Pa or less, introducing 30 sccm of CHF₃ gas to the chamber, maintaining the pressure inside the chamber at 7 Pa, and applying a high frequency powder of 13.56 MHz for plasma discharge. The plasma etching treatment was performed for 30 seconds, 60 seconds, and 90 seconds.

[Method of Measuring Etching Rate]

The film thickness of the surface of the etched substrate was measured at three points using a spectroscopic ellipsometer GES5E (manufactured by Semilab Inc.), and the film thickness was calculated from the average value. Next, the amount of decrease in film thickness due to the etching was calculated from the film thicknesses before and after the etching, and the time (sec) was plotted on the horizontal axis and the amount (nm) of the reduced film thickness was plotted on the vertical axis. The etching rate (nm/sec) was calculated from the inclination of the obtained graph.

[Evaluation of Ashing Characteristics Using O₂ Etching]

The resist underlayer film was formed on a silicon substrate having a size of 3 cm×3 cm, in which a line and space pattern with a height of 200 nm, a projection width of 100 nm, and a width between projections of 100 nm was formed on the surface of the substrate.

The sample obtained by forming the resist underlayer film on the uneven surface of the silicon substrate was divided to perform observation using a SEM on the cross section of one of the sample pieces before ashing.

The ashing characteristics resulting from O₂ etching were evaluated using the other sample piece according to the following method.

The ashing characteristics were evaluated using the same plasma treatment device as the device used for evaluation of the plasma etching characteristics. First, the sample was placed in a chamber, the pressure inside the chamber was reduced to 1 Pa or less, 30 sccm of O₂ gas was introduced to the chamber, and the pressure inside the chamber was maintained at 7 Pa. Next, a high frequency powder of 13.56 MHz was applied thereto for plasma discharge. The plasma etching treatment was carried out in this manner. The plasma etching treatment was performed for 60 seconds.

After the plasma etching treatment, the ashing characteristics were evaluated by performing observation on the cross section of the sample after ashing using a SEM and comparing SEM observation images before and after the plasma etching.

[Formation of Intermediate Layer]

A silicon wafer having a size of 30 mm×30 mm was spin-coated with a solution containing PGMEA and cyclohexanone at a mass ratio of 5/5, which was obtained by dissolving the cyclic olefin polymer according to the present embodiment at a concentration of 10% by mass, in an environment of a temperature of 23° C. to 25° C. and a humidity of 50% to 55% such that the thickness thereof was set to 250 nm under conditions of 1000 rpm for 10 sec, and the coating film was baked at 200° C. for 1 minute in a nitrogen atmosphere.

Example 27

A solution containing PGMEA and cyclohexanone at a mass ratio (PGMEA/cyclohexanone) of 5/5 in which 10% by mass of the polymer 18 obtained in Example 21 was dissolved was prepared, and a 30 mm square silicon wafer was spin-coated with the obtained solution under conditions of 1000 rpm for 10 sec. Next, the resulting sample was heated at 200° C. for 1 minute in a nitrogen atmosphere. This wafer was spin-coated with a PGMEA solution in which 10% by mass of titanium tetraisopropoxide was dissolved after being cooled to room temperature under conditions of 1000 rpm for 10 sec. Next, a wafer formed by heating 200° C. for 1 minute in a nitrogen atmosphere and overcoating the layer of the polymer 18 with TiO₂ was obtained.

As the result of observation of the cross section thereof using a TEM, the interface between the polymer 18 and TiO₂ was clear and flat.

Example 28

A wafer formed by overcoating the layer of the polymer 19 with TiO₂ was obtained in the same manner as that in Example 27 except that the polymer 18 was changed to the polymer 19 obtained in Example 22.

As the result of observation of the cross section thereof using a TEM, the interface between the polymer 19 and TiO₂ was clear and flat. The microphotograph of the cross section is shown in FIG. 4.

Comparative Example 6

A wafer formed by overcoating the layer of the PHS with TiO₂ was obtained in the same manner as that in Example 27 except that the polymer 18 was changed to polyhydroxystyrene (PHS).

As the result of observation of the cross section thereof using a TEM, the interface between PHS and TiO₂ was not clear. Therefore, it was considered that PHS was dissolved and completely mixed with TiO₂ at the time of spin-coating the layer with the PGMEA solution of titanium tetraisopropoxide.

Based on the results described above, in a case where the material of the present invention is used as a resist underlayer film, it was found that the uneven surface of the wafer can be made flat, and intermixing between the intermediate layer or the resist layer and the resist underlayer film does not occur at the time of spin-coating the resist underlayer film with the intermediate layer or the resist layer.

The material for forming an underlayer film according to the first present invention enables provision of a resist underlayer film having sufficient optical characteristics, etching resistance, excellent flatness, and a suppressed amount of volatile components. Accordingly, in a semiconductor device manufacturing step, it is possible to obtain a semiconductor circuit with high integration.

The material for forming an underlayer film according to the second present invention enables realization of a laminate having excellent adhesiveness between the intermediate layer and the resist underlayer film and excellent flatness. Accordingly, in the semiconductor device manufacturing step, it is possible to obtain a semiconductor circuit with high integration.
