Roshow Semiconductor Materials Co., LTD., a subsidiary of Roshow Technology (002617SZ), was established in 2020 and is located in Hefei City, a comprehensive national science Center. Due to the group's strong accumulation in new material equipment manufacturing and production, Roshow has developed into a technologically leading supplier of third generation semiconductor silicon carbide substrate materials. As a new pioneer in the silicon carbide industry, we will take improving the yield of silicon carbide substrate as the starting point, strengthen the collaborative integration of upstream and downstream resources, break through the material bottleneck of the silicon carbide industry, and make solid contributions to the realization of industrial closed-loop from silicon carbide materials to applications.
