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: 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 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: The present disclosure relates to methods and systems for selectively depositing a material comprising silicon and nitrogen onto a substrate comprising a first surface and a second surface, wherein the deposition occurs on the first surface of the substrate more so than on the second surface of the substrate. More specifically, the methods and systems comprise exposing a substrate that comprises a first surface and a second surface to a source of chlorine and a source of silicon, then exposing the substrate to a source of nitrogen to selectively deposit a material comprising silicon and nitrogen on the first surface of the substrate.
