Abstract
An ion deposition sputtering process for producing a titanium nitride film having a resistivity less than about 70 .mu..OMEGA.-cm is disclosed, which comprises the steps of: (1) adjusting a percentage of ionization of a gas phase mixture to a predetermined range by adjusting the power to an ionization source; and (2) adjusting a deposition rate of said film on a substrate to a predetermined range so that a combination of said percentage of ionization of said deposition mixture and said deposition rate produces said film.
