It is reported that this breakthrough reflects the continuous innovation capability of Keyou Semiconductor in silicon carbide crystal growth technology and thermal field design. The self-developed equipment and independent process are important proofs of the company's solid technical strength in the field of wide bandgap semiconductor materials. Silicon carbide, as a third-generation semiconductor material, is a key foundational material for national strategic emerging industries such as new energy vehicles, 5G communications, and rail transit. In recent years, with the rapid development of emerging fields such as artificial intelligence and wearable devices (such as AR glasses), the performance advantages of silicon carbide in high frequency, high power, and high temperature resistance have been further highlighted. The area of a 12 inch substrate is about 2.25 times that of an 8-inch substrate, which means that the number of AR glasses chips that can be produced from a single 12 inch substrate is much higher than that of an 8-inch substrate. In large-scale production, this can significantly reduce the unit cost of processes such as crystal growth, processing, and polishing, and is a key path to reducing the cost of core components in AR glasses.

With the sustained high-speed growth of the global silicon carbide market, large-sized crystals have become a key path to cost reduction and efficiency improvement. Keyou Semiconductor has successfully prepared 12 inch silicon carbide ingots, which can significantly increase chip output and significantly reduce unit costs, injecting stronger development momentum into industries such as new energy, communication, and AR. It is reported that Keyou Semiconductor was established in May 2018. It is a national high-tech enterprise specializing in the research and development of third-generation semiconductor equipment, substrate fabrication, device design, and the transformation of scientific research achievements. Its research and development covers multiple fields such as semiconductor equipment development, crystal growth process, and substrate processing, forming independent intellectual property rights. It has accumulated more than 90 authorized patents and achieved independent and controllable advanced technology. Since its establishment, Keyou Semiconductor has been building a third-generation semiconductor industry university research integration gathering area in Harbin New Area, realizing the full industrial chain closure of silicon carbide materials from raw material purification, equipment manufacturing, crystal growth, substrate processing to epitaxial wafers. It is committed to becoming a major supplier of key materials and high-end equipment for third-generation semiconductors
