Edge termination technique is essential fer the fabrication of high volage devices. A proper edge termination technique is also needed in the fabrication of Silicon Carbide power devices for obtaining a stable high blocking voltage properties. Among the many techniques, the field plate formation is the easiest one that can utilize it for commercial usage. The growth of thick thermal oxide is difficult for SiC, however. In this paper, 6A grade SiC schottky barrier diodes(SBD) were fabricated with field plate edge termination. The oxides which is field plate were formed various methods such as dry oxidation, 10% $N_2O$ nitrided oxidation and PECVD deposition. The reverse characteristics of the SiC SBD with various oxide field plate were investigated.
