Patent ID: 7432184

Claim:
A method of processing a film stack containing two or more metal-containing layers on a substrate in a substrate processing system, comprising: depositing a molybdenum layer to a thickness of about 100 Å to about 1500 Å on the substrate in a first physical vapor deposition (PVD) chamber of the substrate processing system having a first target which comprises molybdenum; transferring the substrate to a second PVD chamber of the same substrate processing system; and depositing a layer of a material selected from the group consisting of aluminum (Al), neodymium (Nd), aluminum neodymium (AlNd), molybdenum nitride (Mo x N y ), copper (Cu), their metal nitrides, metal alloys, and combinations thereof to a thickness of about 1750 Å to about 3500 Å on the surface of the substrate without breaking vacuum in the second PVD chamber having a second target which comprises said material, wherein the thickness of the molybdenum layer is less than the thickness of said material layer, wherein the throughput of the substrate processing system is about 40 substrates or more per hour.
