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.
