    摘要: The current disclosure relates to methods of depositing silicon oxide on a substrate, methods of forming a semiconductor device and a method of forming a structure. The method comprises providing a substrate in a reaction chamber, providing a silicon precursor in the reaction chamber, the silicon precursor comprising a silicon atom connected to at least one oxygen atom, the at least one oxygen atom being connected to a carbon atom, and providing a reactant comprising hydrogen atoms in the reaction chamber to form silicon oxide on the substrate.

    摘要: Vapor deposition processes are provided in which a material is selectively deposited on a first surface of a substrate relative to a second organic surface. In some embodiments a substrate comprising a first surface, such as a metal, semi-metal or oxidized metal or semi-metal is contacted with a first vapor phase hydrophobic reactant and a second vapor phase reactant such that the material is deposited selectively on the first surface relative to the second organic surface. The second organic surface may comprise, for example, a self-assembled monolayer, a directed self-assembled layer, or a polymer, such as a polyimide, polyamide, polyuria or polystyrene. The material that is deposited may be, for example, a metal or metallic material. In some embodiments the material is a metal oxide, such as ZrO2 or HfO2. In some embodiments the vapor deposition process is a cyclic chemical vapor deposition (CVD) process or an atomic layer deposition (ALD) process. In some embodiments the material is deposited on the first surface relative to the second surface with a selectivity of greater than about 50%, greater than about 60%, greater than about 70%, greater than about 80%, greater than about 90% or greater than about 95%.

    摘要: Methods for depositing oxide thin films, such as metal oxide, metal silicates, silicon oxycarbide (SiOC) and silicon oxycarbonitride (SiOCN) thin films, on a substrate in a reaction space are provided. The methods can include at least one plasma enhanced atomic layer deposition (PEALD) cycle including alternately and sequentially contacting the substrate with a first reactant that comprises oxygen and a component of the oxide, and a second reactant comprising reactive species that does not include oxygen species. In some embodiments the plasma power used to generate the reactive species can be selected from a range to achieve a desired step coverage or wet etch rate ratio (WERR) for films deposited on three dimensional features. In some embodiments oxide thin films are selectively deposited on a first surface of a substrate relative to a second surface, such as on a dielectric surface relative to a metal or metallic surface.

    摘要: Methods for selectively depositing oxide thin films on a dielectric surface of a substrate relative to a metal surface are provided. The methods can include at least one plasma enhanced atomic layer deposition (PEALD) cycle including alternately and sequentially contacting the substrate with a first precursor comprising oxygen and a species to be included in the oxide, such as a metal or silicon, and a second plasma reactant. In some embodiments the second plasma reactant comprises a plasma formed in a reactant gas that does not comprise oxygen. In some embodiments the second plasma reactant comprises plasma generated in a gas comprising hydrogen.
