Melting occurs … WebThe crystallization temperature of SiC thin films sputtered from SiC target is about 500°C, below which the films are amorphous. However, the stable amorphous phase is obtained in SiC thin films reactively sputtered from a Si target in a C 2 H 2 or CH 4 gas. 195 Typical sputtering conditions for the deposition of amorphous SiC films are shown in Table 6.52.
