Single crystal β-SiC films have been fabricated on (100)Si substrates through a thermal reaction between the substrate and carbon atoms sublimed from a high purity graphite source. The substrate temperature during the deposition ranged from 600 to 1100°C. The film properties were analyzed by RHEED and x-ray diffraction measurements. RBS measurements and TEM observations have also been made to investigate the film properties. The single crystal β-SiC films grow at and above 1000°C on (100) substrates. The activation energy is found to be around 1.1 eV for the crystallization process.
