Abstract: Methods of treating metal-containing thin films, such as films comprising titanium carbide, with a silane/borane agent are provided. In some embodiments a film including titanium carbide is deposited on a substrate by an atomic layer deposition (ALD) process. The process may include a plurality of deposition cycles involving alternating and sequential pulses of a first source chemical that includes titanium and at least one halide ligand, a second source chemical that includes metal and carbon, where the metal and the carbon from the second source chemical are incorporated into the thin film, and a third source chemical, where the third source chemical is a silane or borane that at least partially reduces oxidized portions of the titanium carbide layer formed by the first and second source chemicals. The treatment can form a capping layer on the metal carbide film.

Abstract: In one aspect, methods of forming smooth ternary metal nitride films, such as TixWyNz films, are provided. In some embodiments, the films are formed by an ALD process comprising multiple super-cycles, each super-cycle comprising two deposition sub-cycles. In one sub-cycle a metal nitride, such as TiN is deposited, for example from TiCl4 and NH3, and in the other sub-cycle an elemental metal, such as W, is deposited, for example from WF6 and Si2H6. The ratio of the numbers of each sub-cycle carried out within each super-cycle can be selected to achieve a film of the desired composition and having desired properties.

Abstract: To create constant partial pressures of the by-products and residence time of the gas molecules across the wafer, a dual showerhead reactor can be used. A dual showerhead structure can achieve spatially uniform partial pressures, residence times and temperatures for the etchant and for the by-products, thus leading to uniform etch rates across the wafer. The system can include differential pumping to the reactor.

Abstract: Methods are provided for selectively depositing a material on a first metal or metallic surface of a substrate relative to a second, dielectric surface of the substrate, or for selectively depositing metal oxides on a first metal oxide surface of a substrate relative to a second silicon oxide surface. The selectively deposited material can be, for example, a metal, metal oxide, metal nitride, metal silicide, metal carbide and/or dielectric material. In some embodiments a substrate comprising a first metal or metallic surface and a second dielectric surface is alternately and sequentially contacted with a first vapor-phase metal halide reactant and a second reactant. In some embodiments a substrate comprising a first metal oxide surface and a second silicon oxide surface is alternately and sequentially contacted with a first vapor phase metal fluoride or chloride reactant and water.
