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. Masking applications employing selective organic films are provided. Post-deposition modification of the organic films, such as metallic infiltration and/or carbon removal, is also disclosed.

Abstract: Methods for selectively forming a target film on a substrate comprising a first dielectric surface and a second metallic surface are disclosed. The methods may include: contacting the substrate with a plasma generated from a hydrogen containing gas, selectively forming a passivation film from vapor phase reactants on the first dielectric surface while leaving the second metallic surface free from the passivation film, and selectively depositing the target film from vapor phase reactants on the second metallic surface relative to the passivation film.

Abstract: Methods for selective deposition are provided. Material is selectively deposited on a first surface of a substrate relative to a second surface of a different material composition. An inhibitor, such as a polyimide layer, is selectively formed from vapor phase reactants on the first surface relative to the second surface. A layer of interest is selectively deposited from vapor phase reactants on the second surface relative to the first surface. The first surface can be metallic while the second surface is dielectric. Accordingly, material, such as a dielectric transition metal oxides and nitrides, can be selectively deposited on metallic surfaces relative dielectric surfaces using techniques described herein.

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: A method of forming a structure including a silicon nitride overlying a titanium nitride layer is disclosed. The method includes forming the titanium nitride layer and the silicon nitride layer in the same reaction chamber—e.g., without a vacuum break—to mitigate oxidation of the titanium nitride layer that might otherwise occur.
