SiC thin films have been prepared by using the RF magnetron sputtering. The deposition parameters have been changed over a wide range to optimize the quality of the films; substrate temperature from 600-1000º C, Ar/CH4 composition from 80/20-50/50 and RF-Power 100-200 Watt. The samples have been characterized by X-Ray diffraction, Rutherdord backscattering, Perfilometry, FTIR spectroscopy and elipsometry. Results show that good quality silicon carbide films can be prepared by using RF-RMS technique.
