Abstract:
Vapor deposition processes are provided in which a material is selectively deposited on a first surface of a substrate relative to a second organic surface. In some embodiments a substrate comprising a first surface, such as a metal, semi-metal or oxidized metal or semi-metal is contacted with a first vapor phase hydrophobic reactant and a second vapor phase reactant such that the material is deposited selectively on the first surface relative to the second organic surface. The second organic surface may comprise, for example, a self-assembled monolayer, a directed self-assembled layer, or a polymer, such as a polyimide, polyamide, polyuria or polystyrene. The material that is deposited may be, for example, a metal or metallic material. In some embodiments the material is a metal oxide, such as ZrO2 or HfO2. In some embodiments the vapor deposition process is a cyclic chemical vapor deposition (CVD) process or an atomic layer deposition (ALD) process. In some embodiments the material is deposited on the first surface relative to the second surface with a selectivity of greater than about 50%, greater than about 60%, greater than about 70%, greater than about 80%, greater than about 90% or greater than about 95%.
