Silicon carbide based films, with a growth rate from 3 to 60 mu m/h, h
ave been obtained by microwave plasma assisted chemical vapor depositi
on (PACVD) using an argon/tetramethylsilane mixture. The effects of th
e main experimental parameters (substrate position and temperature, in
put gas mixture) on the films composition, growth rate and mechanical
properties have been correlated to the plasma characteristics.
