Abstract: The disclosed technology generally relates to semiconductor devices, and relates more particularly to resistive random access memory devices and methods of making the same. In one aspect, a method of forming a resistive random access memory cell of a random access memory device includes forming a first electrode and forming a resistive switching material comprising an oxide of a pnictogen element by atomic layer deposition. The method additionally includes forming a metallic layer comprising the pnictogen element by atomic layer deposition (ALD). The resistive switching material is interposed between the first electrode and the metallic layer.

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 comprising 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 comprises titanium and at least one halide ligand, a second source chemical comprising metal and carbon, wherein the metal and the carbon from the second source chemical are incorporated into the thin film, and a third source chemical, wherein 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. In some embodiments treatment forms a capping layer on the metal carbide film.
