What Guangdong Tianyu Semiconductor does
Guangdong Tianyu Semiconductor, founded in 2009 and based in Dongguan, China, specializes in silicon carbide (SiC) epitaxial wafers, a key material for power semiconductors. It makes 4-, 6- and 8-inch wafers and serves customers in Chinese Mainland, Hong Kong and South Korea. The company was formerly named Dongguan Tianyu Semiconductor Technology Co., Ltd. Its wafers go into chips used in electric vehicles, power supplies, rail transportation, photovoltaics, energy storage and smart grids. Besides selling wafers, it offers contract epitaxy, wafer cleaning and SiC inspection services, and is also involved in device inspection and sales. That makes it a materials supplier to power chipmakers, so its business is tied to demand from EVs and renewable energy.
