Recently, Hantiancheng, an enterprise in the Xiamen Torch High-tech Zone, successfully developed the world's first 12-inch high-quality silicon carbide epitaxial chip, relying on the R&D team's independent technical research. This breakthrough will not only significantly improve the production efficiency of downstream power devices, but will also drastically reduce the unit manufacturing cost of silicon carbide chips, laying a key foundation for large-scale and low-cost applications in the silicon carbide industry. At present, Hantian Tiancheng has begun preparations for the batch supply of 12-inch silicon carbide epitaxial wafers. The product has excellent performance in key performance indicators: epitaxial layer thickness unevenness is controlled within 3%, doping concentration unevenness ≤ 8%, 2mm×2mm chip yield is greater than 96%, which can fully meet the requirements of high-reliability applications in the field of downstream power devices. According to reports, Hantian Tiancheng is the first manufacturer in China to commercialize mass supply of 3 inch, 4 inch, and 6 inch silicon carbide epitaxial wafers. According to Insight Consulting and Research, the company became the world's largest supplier of silicon carbide epitaxial wafers in 2023, with a global market share of over 31% in 2024.
