Abstract: We developed EBAS-100, which is available to 100 mm diameter SiC wafer, for post ion implantation annealing in order to realize silicon carbide (SiC) device with large volume production. EBAS-100 is able to perform the rapid thermal process due to the vacuum thermal insulation and small heat capacity of susceptor.

The bandgap of silicon carbide (3.23 eV for 4H-SiC) is larger than that for silicon (1.12 eV) by about 2.9 times. So, operation above 873 K is feasible. Its electrical breakdown field (3 MV cm −1) is higher than that of silicon (0.3 MV cm −1) by a factor of ten.

So the band gap varies with the poly type from 2.3 eV for 3C-Si C to over 3.0 eV for 6H-SiC to 3.2 eV for 4H-SiC. Due to its small er band gap, 3C-SiC has many advanta ges
