Silicon carbide substrates have many defects and cannot be processed directly. A specific single crystal thin film needs to be grown on them through an epitaxial process to make chip wafers. This thin film is the epitaxial layer. Almost all silicon carbide devices are realized on epitaxial materials. High-quality silicon carbide homogeneous epitaxial materials are the basis for the development of silicon carbide devices. The performance of epitaxial materials directly determines the realization of the performance of silicon carbide devices.

Silicon carbide is reshaping the semiconductor industry for power and high-temperature applications, with its comprehensive properties, from epitaxial substrates to protective coatings to electric vehicles and renewable energy systems.

High purity: The silicon epitaxial layer grown by chemical vapor deposition (CVD) has extremely high purity, better surface flatness and lower defect density than traditional wafers.
