  • Patent number: 8003980
    Abstract: The present invention is drawn to a layered organic device, and a method of forming the same. The method includes steps of applying a first solvent-containing organic layer to a substrate and removing solvent from the first solvent-containing organic layer to form a first solidified organic layer. Additional steps include applying a second solvent-containing organic layer to the first solidified organic layer and removing solvent from the second solvent-containing organic layer to form a second solidified organic layer. The first solidified organic layer can be crosslinked, which suppresses negative impact to components in the first solidified organic layer when the solvent of the second solvent-containing organic layer is deposited on the first solidified organic layer.

  • Patent number: 7947518
    Abstract: This invention discloses that photolithography can be made compatible with the production of electronic devices containing sensitive materials, if the sensitive materials are over-coated with an ultra-thin layer of non-reactive materials (e.g. inorganic oxides) before undergoing photolithographic patterning. This protecting layer isolates the sensitive materials from solvents and etching reactants used in photolithographic patterning, and does not need to be removed from the sensitive materials after patterning is completed. This invention enables photolithography to be applied to the production of electronic devices containing sensitive materials, facilitating the development of commercially viable production processes for these devices.

  • Patent number: 7642145
    Abstract: There is a problem in that when the demand accuracy with respect to a semiconductor pattern dimension comes close to a resist molecule size with miniaturization, the device performance is deteriorated due to edge roughness of a resist pattern to exert a bad influence on the system performance. The present invention overcomes the problem by the procedure in which super-molecules which are small in dimension as compared with the conventional polymers are used as main components, the reaction number required for the change of molecule solubility is made constant and as large as possible, and an acid generator is made clathrate or combinatory n super molecules to make an acid catalyst concentration large. As a result, it is possible to form a pattern of molecular accuracy with high productivity even with respect to the pattern dimension less than 50 nm, thereby realizing the high performance system.

    Abstract: Methods of forming electrical interconnect structures include forming a dielectric layer on a semiconductor substrate and forming a hard mask layer on the dielectric layer. A photoresist layer is patterned on an upper surface of the hard mask layer. This patterned photoresist layer is used as an etching mask during a step to selectively etch the hard mask layer and define an opening therein. This opening exposes the first dielectric layer. The patterned photoresist layer is then stripped from the hard mask layer using an ashing process that exposes the upper surface of the hard mask layer. Following this ashing process, a portion of the first dielectric layer extending opposite the opening is selectively etched using the hard mask layer as an etching mask. During this selective etching step, polymer residues are accumulated directly on the upper surface of the hard mask layer.

    Abstract: The invention includes masking methods. In one implementation, a masking material which includes boron doped amorphous carbon is formed over a feature formed on a semiconductor substrate. The masking material includes at least about 0.5 atomic percent boron. The masking material is substantially anisotropically etched effective to form an anisotropically etched sidewall spacer which includes the boron doped amorphous carbon on a sidewall of the feature. The substrate is then processed proximate the spacer while using the boron doped amorphous carbon-including spacer as a mask. After processing the substrate proximate the spacer, the boron doped amorphous carbon-including spacer is etched from the substrate. Other implementations and aspects are contemplated.

  • Patent number: 7456490
    Abstract: A method and structure for sealing porous dielectrics using silane coupling reagents is herein described. A sealant chain (silane coupling reagent) is formed from at least silicon, carbon, oxygen, and hydrogen and exposed to a porous dielectric material, wherein the sealant chain reacts with a second chain, that has at least oxygen and is present in the porous dielectric defining the pores, to form a continuous layer over the surface of the porous dielectric.

  • Publication number: 20080268656
    Abstract: Provided is a method of forming an oxide-based nano-structured material including growing a nano-structured material using a nano-nucleus having the same composition as the desired oxide-based nano-structured material. A solution is coated on a substrate, the solution including: an organic precursor containing M which is a transition metal or a semi metal; and an organic solvent in which the organic precursor is dissolved. A nano-nucleus having a composition of MxOy is formed on the substrate by annealing the substrate. A nano-structured material having a composition of MxOy is formed by growing the nano-nucleus while supplying a reaction precursor containing M into the nano-nucleus, and the nano-structured material is annealed.

  • Patent number: 7432212
    Abstract: The invention includes methods of processing semiconductor substrates. In one implementation, a semiconductor substrate is provided which has an outer surface. Such surface has a peripheral region received about a peripheral edge of the semiconductor substrate. A layer comprising amorphous carbon is provided over the substrate outer surface. A masking layer is provided outwardly of the amorphous carbon-comprising layer. A resist layer is provided outwardly of the masking layer. At least a portion of the peripheral region of the outer surface includes the amorphous carbon-comprising layer and the resist layer, but is substantially void of the masking layer. The amorphous carbon-comprising layer is patterned using the resist layer and the masking layer effective to form a mask over the semiconductor substrate. After the patterning, the semiconductor substrate is processed inwardly of the mask through openings formed in the mask.

  • Patent number: 7407846
    Abstract: The present method prevents malfunctions in switching caused by a light leakage current in an active matrix type thin film transistor substrate for a liquid crystal display and prevents display failures, by selectively disposing a self assembled monolayer film in a gate electrode-projected region of the surface of an insulator film with high definition, and by selectively improving the orientation order of an organic semiconductor film only in the gate electrode-projected region without improving the order at an irradiated portion with light outside the gate electrode-projected region.

  • Patent number: 7393707
    Abstract: An object of the present invention is to provide an EL display device having high operation performance and reliability. A third passivation film 45 is disposed under the EL element 203 comprising a pixel electrode (anode) 46, an EL layer 47 and a cathode 48, and diffusion of alkali metals from the EL element 203 formed by ink jet method into TFTs is prevented. Further, the third passivation film 45 prevents penetration of moisture and oxygen from the TFTs, and suppress degradation of the EL element 203 by dispersing the heat generated by the EL element 203.

  • Patent number: 7365022
    Abstract: A digital lithographic process first deposits a mask layer comprised of print patterned mask features. The print patterned mask features define gaps into which a target material may be deposited, preferably through a digital lithographic process. The target material is cured or hardened, if necessary, into target features. The mask layer is then selectively removed. The remaining target features may then be used as exposure or etch masks, physical structures such as fluid containment elements, etc. Fine feature widths, narrower the minimum width of the print patterned mask features, may be obtained while realizing the benefits of digital lithography in the manufacturing process.
