Development of the novel electron bombardment anneal system (EBAS) for SiC post ion implantation anneal
We develop the rapid thermal anneal system of the implanted SiC, Electron Bombardment Anneal System (EBAS), which is able to heat up to 1900 ° C with a rate of 320 ° C/min in vacuum. Using this novel system, the annealing of N* implanted SiC samples (total dose: 2.4 x 10(15) cm(-2), thickness: 220 nm) at 1900 ° C for 0.5 min results in a low sheet resistance of 1.39 x 10(3) ohm/sq. with extremely low roughness of the surface (RMS value: 0.32 nm). It is also demonstrated that EBAS can anneal the sample with low electric power consumption.
