KeYou Semiconductor, relying on its independently developed 12-inch silicon carbide crystal growth furnace and thermal field technology, has successfully produced 12-inch silicon carbide ingots. This achievement marks KeYou as one of the few domestic semiconductor companies to master the full set of core technologies for 12-inch silicon carbide crystal growth equipment and processes, realizing a comprehensive independent breakthrough from equipment to materials.
The emergence of 12-inch wafers
This breakthrough not only reflects KeYou's continuous innovation capability in silicon carbide crystal growth technology and thermal field design, but also proves the company's solid technical strength in the wide bandgap semiconductor material field through self-developed equipment and independent processes. 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 like artificial intelligence and wearable devices (such as AR glasses), the high-frequency, high-power, and high-temperature resistance advantages of silicon carbide have become even more prominent.
The area of a 12-inch substrate is approximately 2.25 times that of an 8-inch substrate, which means that the number of chips for AR glasses produced from a single 12-inch substrate is far higher than that from an 8-inch wafer. In large-scale production, this can significantly reduce the unit costs in crystal growth, processing, polishing, and other stages, making it a key path to lowering the cost of core components for AR glasses.
The Chinese AR glasses market will maintain a high compound growth rate. Wellsenn XR estimates that global AR shipments will reach 1.8 million units by 2027. Based on this growth rate and the development trend of the Chinese AR glasses market, a conservative forecast by Qianzhan estimates that shipments in China will approach five million units by 2030. With continuous technological progress and further cost reductions, this market demand is expected to continue growing, accelerating the development of the entire industry chain.
With the global silicon carbide market continuing rapid growth, large-size crystals have become a key path to cost reduction and efficiency improvement. KeYou Semiconductor's successful production of 12-inch silicon carbide ingots can greatly increase chip output and significantly reduce unit costs, injecting stronger development momentum into strategic industries such as new energy, communications, and AR. In the future, KeYou will continue to focus on technological innovation to provide customers with higher-quality customized services and complete process solutions.
