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: The present disclosure relates to methods and apparatuses for selectively depositing silicon and oxygen-comprising material on a first surface of a substrate relative to a second surface of the substrate by a cyclic deposition process, the method comprising providing a substrate in a reaction chamber; providing a metal or metalloid catalyst to 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 an oxygen precursor comprising oxygen and hydrogen into the reaction chamber in vapor phase to form silicon and oxygen-comprising material on the first surface. The disclosure further relates to vapor deposition assemblies.

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