About US
CSMH vigorously promotes the localization of semiconductor materials such as high-quality diamond wafer, diamond heat sink, GaN-on-diamond, and sapphire AIN. The growth face roughness of diamond wafer is within 1nm; The thermal conductivity of diamond heat sinks is as high as 1000-2000W/m.k, which are widely used in 5G base stations, lasers, new energy vehicles, new energy photovoltaics and aerospace; Our GaN-on-diamond epitaxial wafers stand out in the domestic market and the sapphire AIN are expected to make a qualitative leap in the photoelectric conversion rate of deep ultraviolet LEDs.
