Abstract: Atomic layer etching (ALE) processes are disclosed. In some embodiments, the methods comprise at least one etch cycle in which the substrate is alternately and sequentially exposed to a first vapor phase non-metal halide reactant and a second vapor phase halide reactant. In some embodiments both the first and second reactants are chloride reactants. In some embodiments the first reactant is fluorinating gas and the second reactant is a chlorinating gas. In some embodiments a thermal ALE cycle is used in which the substrate is not contacted with a plasma reactant.

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.
