Supply 4 inch SiC Wafer Manufacturer 100mm N type SiC Substrate

Are you looking for buy 4 inch SiC wafer？But most factories stopped 4 inch SiC wafer production many years. Just contact us--HMT company! we can still supply 4 inch SiC substrate wafer including conductive N type and semi-insulated SI type with D grade R grad an P grade. Not only 4 inch SiC substrate, we also supply Raw Cut 4 inch SiCwafer， 4 inch SiC boules. Free free to contact HMT!

SiC has high energy conversion efficiency, and will not decrease with the increase of frequency, SiC device operating frequency can reach 10 times of silicon based devices, the same specification of SiC MOSFET total energy loss is only 30% of silicon based IGBT.  SiC materials will gradually replace silicon in the fields of high temperature, high frequency and high frequency, and play an important role in 5G communications, aerospace, new energy vehicles and smart power grids.  

SiC substrate is divided according to resistivity: semi-insulating SiC substrate: refers to the SiC substrate with resistivity higher than 105 ω ·cm, which is mainly used to manufacture gallium nitride microwave rf devices.  Microwave radio frequency devices are basic components in the field of wireless communication. China is vigorously developing 5G technology to release the demand for SiC substrates.
