摘要:
The techniques and procedures utilized to sputter the silicides of Mo, Ta, and Ti in a Varian 3180/3190TMsystem1are presented. The electrical resistivity of a thin film is a sensitive indicator of film purity and/or uniformity.2,3The affect of various system parameters on film resistivity is also presented. Variable parameters investigated included argon pressure, cathode power, sputtering rate, wafer temperature, and wafer bias.
