4.Application of 4H Semi-insulating SiC crystal substrate and wafer
 
Silicon carbide (SiC) crytsals have unique physical and electronic properties. Silicon carbide – based devices have been used for short – wavelength photoelectricity, high – temperature, anti – radiation applications. High power and high frequency electronic devices made from SiC are superior to those based on Si and GaAs, and 4H Semi-insulating SiC wafers are mainly used in Power device and RF device.
