Abstract: The present disclosure is directed to methods and systems for depositing a material within a gap of a substrate in a cyclic deposition process. The methods and systems utilize an inhibitor to preferentially blocks chemisorption of a subsequently introduced first precursor at a portion of available chemisorption sites in the gap to promote deeper penetration of the first precursor into the gap and/or more uniform chemisorption of the first precursor in the gap used in forming a desired material.

Abstract: Methods and systems for selectively depositing dielectric films on a first surface of a substrate relative to a passivation layer previously deposited on a second surface are provided. The methods can include at least one cyclical deposition process used to deposit material on the first surface while the passivation layer is removed, thereby preventing deposition over the passivation layer.

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: 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.
