Guangdong Tianyu Semiconductor Co., Ltd. was established in 2009. It is the first enterprise to realize the industrialization of the third-generation semiconductor SiC epitaxial wafers in China, and it is also the first domestic enterprise to obtain the automotive quality certification (IATF 16949) for SiC semiconductor materials. On December 5, 2025, the company successfully listed on the Main Board of Hong Kong Stock Exchange (Stock Code: 02658.HK), becoming the industry's first SiC epitaxial enterprise to be listed on the H-share market.
Over the years，we have been consistently contributing to the industry with our production processes , conducting R&D focusing on the industrialization of SiC epitaxial wafers.Through independent R&D, we have mastered the key technologies and processes necessary for the entire SiC epitaxial wafer production cycle required to manufacture 600–30,000V unipolar and bipolar power devices.These devices are ultimately applied in sectors such as new energy industries (including electric vehicles, photovoltaics, charging stands, and energy storage), rail transportation, smart grids, general aviation (such as electric vertical take-off and landing ‘eVTOL’) and home appliances.
