D grade SiC Boule Supplier 150mm 6 inch 200mm 8 inch

China SiC Boule SiC crystals Manufacturer HMT company providing D grade SiC Boule with favourable price. Both 6 inch and 8 inch are available in HMT. We also producing  un-polishing SiC Wafer, which we called SiC As-cut wafer. No matter customer purchase SiC boule or SiC as-cut wafer, we always provide best service and high quality of SiC products.

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.
