Claim 0:
1. A method of selectively depositing a metal oxide on a metal surface of a substrate relative to a transition metal oxide surface of the substrate, wherein the metal surface is an Al, Cu, Co, Ni, W, Nb, Fe, or Mo surface, the method comprising, in order:
forming a passivation blocking layer on the metal surface;
selectively passivating the transition metal oxide surface relative to the metal surface, wherein selectively passivating the transition metal oxide surface comprises exposing the transition metal oxide surface to a silylation agent;
removing the passivation blocking layer from the metal surface; and
selectively depositing the metal oxide from vapor phase reactants on the metal surface relative to the passivated transition metal oxide surface,
wherein the vapor phase reactants comprise a hydrophobic metal reactant comprising one or more hydrophobic ligands, and
wherein at least one of the hydrophobic ligands comprises C.
