Abstract: Superjunction technology is believed to reach the optimal specific on-resistance and breakdown voltage trade-off. It has become a mainstream technology in silicon high-voltage metal oxide semiconductor field effect transistor devices. Numerous efforts have been conducted to employ the same concept in silicon carbide devices. These works are summarized here.

Key words: silicon carbide (SiC)power semiconductor devicessuperjunction (SJ)process development
