PROCESS FOR PRODUCING SILICON CARBIDE CRYSTALS HAVING INCREASED MINORITY CARRIER LIFETIMES |
摘要 |
A process is described for producing silicon carbide crystals having increased minority carrier lifetimes. The process includes the steps of heating and slowly cooling a silicon carbide crystal having a first concentration of minority carrier recombination centers such that the resultant concentration of minority carrier recombination centers is lower than the first concentration.
