Claim 0:
1. A process for the vapor deposition of a molybdenum or tungsten-containing film onto a surface, comprising:
introducing into a reaction zone containing the surface, a precursor at a first precursor concentration and a reducing gas until a film has a thickness of about 3 Å to about 25 Å has been deposited on the surface;
introducing into the reaction zone, the precursor at a second precursor concentration and a reducing gas, until deposition of the film having a desired thickness is achieved, and
wherein the first precursor concentration is about 1 to about 75 percent to the second precursor concentration in the reaction zone and wherein the film with a thickness of about 3 Å to about 25 Å is deposited with a smooth surface morphology.
