Hefei Century Gold Core Semiconductor Co., Ltd. (hereinafter referred to as "Century Gold Core") signed an order for SiC substrate wafers with a Japanese customer. According to the agreement, Century Gold Core will deliver a total of 130,000 8-inch SiC substrates to the customer for three consecutive years in 2024, 2025 and 2026, with an order value of approximately US$200 million.
At present, Century Goldcore's 6-inch SiC substrate wafer has reached order cooperation with several domestic head epitaxy and wafer manufacturers; the company's 8-inch SiC substrate wafer has completed multiple batches of product verification with domestic customers HT and ZDK. At the same time, Product verification is ongoing with Taiwan's HY, JJ, South Korea's GJ Laboratory, and SX, and orders are expected to be completed in the second half of 2024.
News from Hefei Century Gold Core Semiconductor Co., Ltd. shows that 8-inch SiC substrate wafers have also made major breakthroughs recently. The 8-inch SiC single crystal growth technology developed by the company can repeatedly grow crystals with 100% 4H crystal form, a diameter greater than 200mm, and a thickness exceeding 10mm. . An 8-inch processing line has also been built simultaneously, which will support the growth of 8-inch single crystals. Through further optimization of the process, the company's 8-inch SiC ingot is expected to have a thickness of more than 20mm.
In February 2024, the 8-inch SiC processing line of the Hefei factory was officially connected and entered small batch production. It is expected to achieve mass production delivery in July 2024.
