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 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: Passivation layers to inhibit vapor deposition can be used on reactor surfaces to minimize deposits while depositing on a substrate housed therein, or on particular substrate surfaces, such as metallic surfaces on semiconductor substrates to facilitate selective deposition on adjacent dielectric surfaces. Passivation agents that are smaller than typical self-assembled monolayer precursors can have hydrophobic or non-reactive ends and facilitate more dense passivation layers more quickly than self-assembled monolayers, particularly over complex three-dimensional structures.

Abstract: The disclosure relates to methods, processing assemblies, reactants and vapor deposition vessels for selective vapor-phase deposition of inhibitor material on a substrate comprising two surfaces. In some embodiments of the disclosure, the inhibition material is deposited on the first surface of the substrate, whereas substantially no inhibitor material is deposited on the second surface of the substrate. The inhibitor material is formed by contacting the substrate with a vapor-phase inhibitor reactant comprising a silicon atom bonded to an oxygen atom and to a second atom selected from nitrogen and halogens.

Abstract: The disclosure relates to methods, processing assemblies, for selective vapor-phase deposition of inhibitor material on a substrate comprising two surfaces. In some embodiments of the disclosure, the inhibition material is deposited on the first conductive surface of the substrate, whereas substantially no inhibitor material is deposited on the second surface of the substrate. The inhibitor material is formed by contacting the substrate with a vapor-phase inhibitor reactant comprising alkylsilane having at least one alkoxy group bonded to a silicon atom.

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.
