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: A process for forming a silicon oxycarbide (SiOC) thin film on a substrate in a reaction space by a plurality of deposition cycles is provided. At least one deposition cycle includes contacting a surface of the substrate with a silicon precursor that does not comprise nitrogen and a second reactant that includes reactive species. The reactive species are generated from a gas that flows continuously to the reaction space throughout the at least one deposition cycle. A ratio of a wet etch rate of the SiOC thin film to a wet etch rate of thermal silicon oxide is less than 5.

Abstract: Methods for depositing silicon oxycarbonitride (SiOCN) thin films on a substrate in a reaction space are provided. The methods can include at least one plasma enhanced atomic layer deposition (PEALD) cycle including alternately and sequentially contacting the substrate with a silicon precursor and a second reactant that does not include oxygen. In some embodiments the methods allow for the deposition of SiOCN films having improved acid-based wet etch resistance.

Abstract: Methods of forming silicon nitride thin films on a substrate in a reaction space under high pressure are provided. The methods can include a plurality of plasma enhanced atomic layer deposition (PEALD) cycles, where at least one PEALD deposition cycle comprises contacting the substrate with a nitrogen plasma at a process pressure of 20 Torr to 500 Torr within the reaction space. In some embodiments the silicon precursor is a silyl halide, such as H2SiI2. In some embodiments the processes allow for the deposition of silicon nitride films having improved properties on three dimensional structures. For example, such silicon nitride films can have a ratio of wet etch rates on the top surfaces to the sidewall of about 1:1 in dilute HF.

Abstract: Methods for controlling the formation of oxygen containing thin films, such as silicon oxycarbide (SiOC) and silicon oxycarbonitride (SiOCN) thin films, on a substrate in a reaction space are provided. The methods can include at least one plasma enhanced atomic layer deposition (PEALD) cycle including alternately and sequentially contacting the substrate with a silicon precursor that comprises oxygen and a second reactant that does not include oxygen. In some embodiments the plasma power can be selected from a range to achieve a desired step coverage or wet etch rate ratio (WERR) for films deposited on three dimensional features.

Abstract: Methods and apparatus for vapor deposition of an organic film are configured to vaporize an organic reactant at a first temperature, transport the vapor to a reaction chamber housing a substrate, and maintain the substrate at a lower temperature than the vaporization temperature. Alternating contact of the substrate with the organic reactant and a second reactant in a sequential deposition sequence can result in bottom-up filling of voids and trenches with organic film in a manner otherwise difficult to achieve.
