Abstract
An inert gas, such as helium, nitrogen, or argon, is used for pressurization and stabilization in a chemical vapor deposition process that occurs in an ambient temperature in excess of 400.degree. C. Using the inert gas in the pressurization and stabilization stages of the chemical vapor deposition process eliminates the formation of tungsten oxides on tungsten studs, lines and other devices in the substrate, thereby eliminating the variable contact resistance and other problems associated with tungsten oxides.
