8inch SiC Epitaxial Wafer Diameter 200mm Thickness 500μm 4H-N Type
As a core material supplier in China's SiC industry chain, ZMSH independently develops 8-inch SiC epitaxial wafers based on a mature large-diameter wafer growth technology platform. Utilizing Chemical Vapor Deposition (CVD), a uniform single-crystal film is formed on our high-purity SiC substrate. Key features include:
Compared to traditional 6-inch wafers, the 8-inch wafer increases usable area by 78%, reducing unit device costs by ~30% through automated production, making it ideal for EVs, industrial power supplies, and other large-scale applications.
