Abstract: A method for selectively depositing a metal oxide film is disclosed. In particular, the method comprises pulsing a metal or semi-metal precursor onto the substrate and pulsing an organic reactant onto the substrate. A reaction between the metal or semi-metal precursor and the organic reactant selectively forms a metal oxide film on either a dielectric layer or a metal layer.

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, polyurea 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%.

Abstract: Processes are provided herein for deposition of organic films. Organic films can be deposited, including selective deposition on one surface of a substrate relative to a second surface of the substrate. For example, polymer films may be selectively deposited on a first metallic surface relative to a second dielectric surface. Selectivity, as measured by relative thicknesses on the different layers, of above about 50% or even about 90% is achieved. The selectively deposited organic film may be subjected to an etch process to render the process completely selective. Processes are also provided for particular organic film materials, independent of selectivity.

Abstract: A process is provided for depositing a substantially amorphous titanium oxynitride thin film that can be used, for example, in integrated circuit fabrication, such as in forming spacers in a pitch multiplication process. The process comprises contacting the substrate with a titanium reactant and removing excess titanium reactant and reaction byproducts, if any. The substrate is then contacted with a second reactant which comprises reactive species generated by plasma, wherein one of the reactive species comprises nitrogen. The second reactant and reaction byproducts, if any, are removed. The contacting and removing steps are repeated until a titanium oxynitride thin film of desired thickness has been formed.
