2 inch SiC Wafer manufacturers

Purchase 2 inch Polished SiC Wafer from manufacturer in HMT. We are one of the professional SiC Wafer manufacturer in China, we can offer 50.8mm 2 inch SiC Substrate Wafer, 2 inch As cut SiC Wafer and 2 inch SiC Crystal Boules with best price on the market. Actually 2 inch SiC Wafers were stop production for most manufacturers, but we still keep few capacity allocation for some customers. These substrates are made from silicon carbide (SiC), a compound known for its excellent thermal conductivity, high breakdown voltage, and resistance to harsh environmental conditions.

Unlike traditional silicon-based device, the quality of the SiC substrate and the surface properties can't meet the requirements of manufacturing devices directly, so in manufacturing high power and high voltage high frequency components, can not directly on the SiC substrate production device, and must be additional deposition of a high quality epitaxial single crystal substrate material, and manufacture of various types of devices on the epitaxial layer. 

At present, SiC is the use of homogenous epitaxial growth technology, equipment and growth technology has been relatively mature, can grow more than 100~200μm SiC epitaxial material, but in the epitaxial growth by the substrate quality and processing level, will produce defects.
