Abstract: Methods are provided herein for deposition of oxide films. Oxide films may be deposited, including selective deposition of oxide thin films on a first surface of a substrate relative to a second, different surface of the same substrate. For example, an oxide thin film such as an insulating metal oxide thin film may be selectively deposited on a first surface of a substrate relative to a second, different surface of the same substrate. The second, different surface may be an organic passivation layer.

Abstract: Methods are provided for selectively depositing a material on a first metal or metallic surface of a substrate relative to a second, dielectric surface of the substrate, or for selectively depositing metal oxides on a first metal oxide surface of a substrate relative to a second silicon oxide surface. The selectively deposited material can be, for example, a metal, metal oxide, metal nitride, metal silicide, metal carbide and/or dielectric material. In some embodiments a substrate comprising a first metal or metallic surface and a second dielectric surface is alternately and sequentially contacted with a first vapor-phase metal halide reactant and a second reactant. In some embodiments a substrate comprising a first metal oxide surface and a second silicon oxide surface is alternately and sequentially contacted with a first vapor phase metal fluoride or chloride reactant and water.

Abstract: Methods for selective deposition, and structures thereof, are provided. Material is selectively deposited on a first surface of a substrate relative to a second surface of a different material composition. A passivation layer is selectively formed from vapor phase reactants on the first surface while leaving the second surface without the passivation layer. A layer of interest is selectively deposited from vapor phase reactants on the second surface relative to the passivation layer. The first surface can be metallic while the second surface is dielectric, or the second surface is dielectric while the second surface is metallic. Accordingly, material, such as a dielectric, can be selectively deposited on either metallic or dielectric surfaces relative to the other type of surface using techniques described herein. Techniques and resultant structures are also disclosed for control of positioning and shape of layer edges relative to boundaries between underlying disparate materials.

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%.
