A. Azens et al., CHEMICALLY ENHANCED SPUTTERING IN FLUORINE-CONTAINING PLASMAS - APPLICATION TO TUNGSTEN OXYFLUORIDE, Thin solid films, 254(1-2), 1995, pp. 1-2
Tungsten oxyfluoride films were prepared by reactive d.c. magnetron sp
uttering in plasmas containing O-2 + CF4. Physical and chemical effect
s on the sputter rate were elucidated by changing the temperature of t
he sputter target. Elevated target temperatures yielded strongly enhan
ced rates, proving that chemical effects can be strong.
