Roshow Technoiogy Co.Ltd(002617) on January 6, when accepting the agency's investigation, it said that the company's 6-inch silicon carbide substrate wafer has been sold, and it is mainly aimed at downstream SBD application scenarios. China's 6-inch conductive silicon carbide substrate for MOS applications will be in the sample submission certification stage before 2022q2. After the cost of silicon carbide decreases in the future, it can widely replace silicon-based power devices. The company has a plan to develop 8-inch chips. At present, all equipment is 6-8-inch compatible. The layout of cutting, grinding and polishing equipment is synchronized with wolfspeed. For a long time, China's silicon carbide conductive substrate is still in short supply. From 22q2, the company can realize the supply capacity of thousands of pieces per month.
