  • Patent number: 9564312
    Abstract: Methods of selectively inhibiting deposition of silicon-containing films deposited by atomic layer deposition are provided. Selective inhibition involves exposure of an adsorbed layer of a silicon-containing precursor to a hydrogen-containing inhibitor, and in some instances, prior to exposure of the adsorbed layer to a second reactant. Exposure to a hydrogen-containing inhibitor may be performed with a plasma, and methods are suitable for selective inhibition in thermal or plasma enhanced atomic layer deposition of silicon-containing films.

  • Publication number: 20140302239
    Abstract: The present invention provides a method of producing polycrystalline silicon in which silicon is precipitated on a silicon core wire to obtain a polycrystalline silicon rod. In an initial stage (former step) of a precipitation reaction, a reaction rate is not increased by supplying a large amount of source gas to a reactor but the reaction rate is increased by increasing a concentration of the source gas to be supplied, and in a latter step after the former step, the probability of occurrence of popcorn is reduced using an effect of high-speed forced convection caused by blowing the source gas into the reactor at high speed. Thus, a high-purity polycrystalline silicon rod with little popcorn can be produced without reducing production efficiency even in a reaction system with high pressure, high load, and high speed.

    Abstract: Apparatus and method for plasma deposition of thin film photovoltaic materials at microwave frequencies. The apparatus avoids deposition on windows or other microwave transmission elements that couple microwave energy to deposition species. The apparatus includes a microwave applicator with conduits passing therethrough that carry deposition species. The applicator transfers microwave energy to the deposition species to transform them to a reactive state conducive to formation of a thin film material. The conduits physically isolate deposition species that would react to form a thin film material at the point of microwave power transfer. The deposition species are separately energized and swept away from the point of power transfer to prevent thin film deposition. The invention allows for the ultrafast formation of silicon-containing amorphous semiconductors that exhibit high mobility, low porosity, little or no Staebler-Wronski degradation, and low defect concentration.

  • Publication number: 20100247803
    Abstract: A chemical vapor deposition (CVD) method for depositing a thin film on a surface of a substrate is described. The CVD method comprises disposing a substrate on a substrate holder in a process chamber, and introducing a process gas to the process chamber, wherein the process gas comprises a chemical precursor. The process gas is exposed to a non-ionizing heat source separate from the substrate holder to cause decomposition of the chemical precursor. A thin film is deposited upon the substrate.

  • Patent number: 7651726
    Abstract: A process of obtaining silicon nitride (Si3N4) surface coatings on ceramic pieces and components by impregnation of the surfaces of the ceramic pieces with silicon powder suspensions with a particle size preferably less than 200 ?m. The thickness of the coatings depends on the impregnation time and on the properties of the slip and the ceramic piece. The subsequent nitridation of the coating by thermal treatment at temperatures between 1300° C. and 1500° C. in N2 atmospheres leads to a continuous Si3N4 coating. The chemical stability and compatibility between Si3N4 and molten silicon enables its application in silicon metallurgy, in manufacturing crucibles for silicon fusion or for housing said molten silicon, in manufacturing pipes and chutes for its transport or in manufacturing different components for its subsequent purification.

  • Patent number: 7625609
    Abstract: A method of forming a silicon nitride film which can form a silicon nitride film having a high film stress at a low process temperature is described herein. The method includes the steps of (a) supplying dichlorosilane into a reaction chamber containing a process object, thereby allowing chemical species originated from dichlorosilane as a precursor to be adsorbed on the process object; (b) hydrogenating chlorine contained in the chemical species, thereby removing the chlorine from the chemical species; and (c) supplying ammonia radicals into the reaction chamber, thereby nitriding the chemical species, from which the chlorine has been removed, by the ammonia radicals to, deposit resultant silicon nitride on the process object, wherein the steps (a), (b) and (c) are performed repeatedly for plural times in that order, thereby a silicon nitride film of a desired thickness is formed on a semiconductor wafer.

  • Patent number: 7604841
    Abstract: A method for extending time between chamber cleaning processes in a process chamber of a processing system. A particle-reducing film is formed on a chamber component in the process chamber to reduce particle formation in the process chamber during substrate processing, at least one substrate is introduced into the process chamber, a manufacturing process is performed in the process chamber, and the at least one substrate is removed from the process chamber. The particle-reducing film may be deposited on a clean chamber component or on a material deposit formed on a chamber component. Alternatively, the particle-reducing film may be formed by chemically modifying at least a portion of a material deposit on a chamber component. The particle-reducing film may be formed after each manufacturing process or at selected intervals after multiple manufacturing processes.

  • Patent number: 7592273
    Abstract: A method of forming a semiconductor device comprises providing a portion of a semiconductor device structure, wherein the portion includes a region susceptible to hydrogen incorporation due to subsequent device processing. For example, the subsequent device processing can include one or more of (i) forming a layer over the region, wherein the layer includes hydrogen and (ii) using gases containing hydrogen in a plasma for the subsequent device processing, wherein the semiconductor device is subject to an undesirable device characteristic alteration by hydrogen incorporation into the region. The method further comprises forming a hydrogen barrier layer overlying the region, wherein the hydrogen barrier layer prevents substantial migration of hydrogen made available due to the subsequent device processing into the underlying region. The method further includes performing the subsequent device processing.

  • Patent number: 7560581
    Abstract: Tungsten nitride films were deposited on heated substrates by the reaction of vapors of tungsten bis(alkylimide)bis(dialkylamide) and a Lewis base or a hydrogen plasma. For example, vapors of tungsten bis(tert-butylimide)bis(dimethylamide) and ammonia gas supplied in alternate doses to surfaces heated to 300° C. produced coatings of tungsten nitride having very uniform thickness and excellent step coverage in holes with aspect ratios up to at least 40:1. The films are metallic and good electrical conductors. Suitable applications in microelectronics include barriers to the diffusion of copper and electrodes for capacitors. Similar processes deposit molybdenum nitride, which is suitable for layers alternating with silicon in X-ray mirrors.

  • Publication number: 20090060820
    Abstract: The present invention includes a step of separating an effluent produced in a hydrogenation step of making tetrachlorosilane (STC) react with hydrogen into trichlorosilane (TCS), into a chlorosilane fraction containing a hydrocarbon and a TCS fraction, and a chlorination step of making the chlorosilane fraction containing the hydrocarbon react with chlorine to form STC and a substance containing a chlorinated hydrocarbon, wherein the effluent containing STC produced in the chlorination step is circulated to the hydrogenation step. In the chlorination step, the chlorosilane fraction containing a hydrocarbon (capable of containing hyper-hydrogenated chlorosilanes) having a boiling point close to TCS is hyper-chlorinated to be converted and acquire a higher boiling point, which facilitates the hyper-chlorinated chlorosilanes and the hyper-chlorinated hydrocarbons to be separated into high concentration, and increases the purity of TCS to be finally obtained.
