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: A method for forming a V-NAND device is disclosed. Specifically, the method involves deposition of at least one of semiconductive material, conductive material, or dielectric material to form a channel for the V-NAND device. In addition, the method may involve a pretreatment step where ALD, CVD, or other cyclical deposition processes may be used to improve adhesion of the material in the channel.

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.
