Abstract: Methods for selective deposition of silicon oxide films on metal or metallic surfaces relative to dielectric surfaces are provided. A dielectric surface of a substrate may be selectively passivated relative to a metal or metallic surface, such as by exposing the substrate to a silylating agent. Silicon oxide is then selectively deposited on the metal or metallic surface relative to the passivated oxide surface by contacting the metal surface with a metal catalyst and a silicon precursor comprising a silanol.

Abstract: Methods and vapor deposition assemblies of selectively depositing material comprising silicon and oxygen on a first surface of a substrate relative to a second surface of the substrate by a cyclic deposition process are disclosed. The methods comprise providing a substrate into a reaction chamber, providing a metal or metalloid catalyst into the reaction chamber in a vapor phase, providing a silicon precursor comprising an alkoxy silane compound into the reaction chamber in a vapor phase and providing a plasma into the reaction chamber to form a reactive species for forming a material comprising silicon and oxygen on the first surface. The methods may comprise subcycles for, for example, adjusting the proportions of material components.

Abstract: Methods for selective deposition are provided. Material is selectively deposited on a first surface of a substrate relative to a second surface of a different material composition. An inhibitor, such as a polyimide layer, is selectively formed from vapor phase reactants on the first surface relative to the second surface. A layer of interest is selectively deposited from vapor phase reactants on the second surface relative to the first surface. The first surface can be metallic while the second surface is dielectric. Accordingly, material, such as a dielectric transition metal oxides and nitrides, can be selectively deposited on metallic surfaces relative dielectric surfaces using techniques described herein.
