II-VI Incorporated announced that it has been selected by Dongguan Tianyu Semiconductor Technology Co. Ltd., as its primary strategic partner for supply of 150 mm SiC substrates for power electronics. The electrification of the transportation infrastructure is driving a market transition to power electronics based on SiC, a third-generation or wide-bandgap semiconductor, which enables power electronics to be smaller, more efficient, and with lower total system-level cost of ownership compared with silicon-based devices. Tianyu has recognized II-VI as a leading global supplier of high-quality 150 mm SiC with a long history of innovation and ability to achieve scale along with an aggressive 200 mm substrate roadmap.
