Abstract

Provided are methods of forming a ternary metal nitride film and more specifically, a TaSiN film. A metal nitride film, or TaN film, is deposited on a substrate with plasma treatment. A SiN layer is deposited on the metal nitride, or TaN, film to form a metal-SiN, or TaSiN, film. The film is then annealed to provide a metal nitride film with stable resistivity.
