SiC substrate factory in china 4 inch 6 inch SiC Epi wafer
as the leading manufacturer, Homray Material Technology offers 4 inch and 6 inch SiC Wafer with production grade and ultralow mpd grade. the ultra low mpd grade of SiC substrate wafer  is ≤1cm-2.

Electronics based on SiC shows advantages compared to Si-devices, where environmental conditions are adverse, i.e. Ionizing radiation, heat-aggressive chemicals. for instance, SiC-based electronics would help to reduce weight and therefore costs of spacecraft, since SiC-devices showed to be much more resistant to ionizing radiation than Si-devices. Thus, a reduction of radiation-shielding is possible. Further, they may reduce or eliminate the use of cooling systems that have to be implemented as soon as Si-electronics is used.
