Abstract:
Described are methods for controlling the doping of metal nitride films such as TaN, TiN and MnN. The temperature during deposition of the metal nitride film may be controlled to provide a film density that permits a desired amount of doping. Dopants may include Ru, Cu, Co, Mn, Mo, Al, Mg, Cr, Nb, Ta, Ti and V. The metal nitride film may optionally be exposed to plasma treatment after doping.

Claim (Index 19):
A method for depositing a barrier film, the method comprising:\n depositing a tantalum nitride film on a dielectric film on a substrate surface, wherein a temperature during the tantalum nitride deposition is controlled to control a density of the tantalum nitride film, the density of the tantalum nitride film is less than or equal to about 9.5 g/cm 3 ; doping the tantalum nitride film with one or more dopants at a temperature that does not exceed about 300\u00b0 C., the dopants comprising one or more of aluminum or manganese; and diffusing one or more of the dopants through the tantalum nitride film to the dielectric film, wherein there is no plasma treatment during deposition of the tantalum nitride film or between deposition of the tantalum nitride film and doping of the tantalum nitride film.
