Abstract

Effect of post-metallization annealing (PMA) on the quality of the thermally grown SiO₂ on 6H- and 4H-SiC has been systematically studied. It is found that under a carefully controlled and optimized PMA condition, it is possible to reduce the effective fixed charge density for both n type and p type 6H- and 4H-SiC. The study covers an annealing temperature range of 400 °C to 600 °C in forming gas (5% hydrogen in nitrogen) for various periods of time. Optimum annealing conditions for both 6H- and 4H-SiC will be reported. Also reported are excellent D_it values for both p type 6H- and p type 4H-SiC/SiO₂ structures.
