    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.

    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.
