The commercial battle for next-generation power semiconductors is evolving. IGBTs, SiC and other technologies are geared for the niche-oriented markets at 1,700 volts and higher. But what is the best technology for the larger 600- and 1,200-volt markets? both super-junction MOSFETs and IGBTs are ramping up on 300mm wafers, making them less expensive than GaN and SiC. In comparison, SiC MOSFETs are ramping up on 100mm wafers, while GaN-on-silicon is running on 150mm substrates. This report analyzes and forecasts the traditional power semiconductor market as well as next generation devices. Market shares of vendors by type are presented.
