Abstract:
1. A process of PECVD deposition comprising the steps of: providing an ion promoting atmosphere comprising at least a precursor gas, a reactant gas, and a chemically inert reactive species promoter gas; and contacting a substrate with a plasma formed in the ion promoting atmosphere, having a composition of approximately 50 to 90% of a metal-containing gas in said ion promoting atmosphere at a pressure and temperature range sufficient for film deposition of said metal at a deposition rate of about 0.60 microns per minute wherein said step of contacting a substrate with a plasma comprises having a temperature range of approximately 150 to 400 degrees Celsius; and wherein said step of contacting a substrate with a plasma comprises having a pressure range of 1 mTorr to 1.0 Torr.
