Abstract: A method for forming a metal nitride film with good film closure at low temperatures is disclosed. The method may comprise utilizing plasma to form NH and NH2 radicals to allow for the formation of the metal nitride at low temperatures. The method may also comprise flowing an etch gas to result in an amorphous film with uniform thickness. The method may also comprise flowing an alkyl hydrazine to inhibit three-dimensional island growth of the metal nitride film.
