The yield rate exceeds 50%, and Global Silicon, the world's third largest silicon wafer factory, will trial production of 8-inch SiC next year

According to news from this site on October 27, Xu Xiulan, chairman of Global Wafers, the world’s third largest silicon wafer manufacturer, said that the company has overcome many technical difficulties in mass production of silicon carbide (SiC) wafers and has already Push SiC wafers to 8 inches to keep pace with major international manufacturers.

Xu Xiulan estimates that small batch shipments of 8-inch SiC products will begin in the fourth quarter of 2024, with significant growth in 2025 and accounting for more than 6-inch wafers by 2026.

Global Wafer stated that it currently has good control over the 8-inch wafer yield,

has exceeded 50%, and there is room for further improvement. Deliveries will begin in the first half of next year. sample.

This site learned from the report that Xu Xiulan said that customers all hope that Global Wafer will teach the transition from 6-inch to 8-inch SiC mass production, mainly Customers are from the automotive sector.

Global Wafer has designed and developed a specialized silicon carbide crystal growth furnace (Crystal Growth Furnace), which enhances material quality control and reduces crystal growth costs.

SiC’s high hardness and brittleness make wafer processing challenging, but Global Wafer uses higher process precision and more efficient wafer handling methods to achieve ultra-thin SiC wafer processing.
