Silicon carbide applicaiton in semiconductor industry
Silicon carbide (SIC) is also called emery sand.It is made of quartz sand, petroleum coke, wood chips, salt and other raw materials. In fact, silicon carbide was discovered long ago.
It owns the following advantages:high thermal conductivity, small thermal expansion coefficient, good abrasion resistance, high hardness (Mo’s hardness is 9.4, second only to the world’s hardest diamond (level 10)), excellent thermal conductivity, strong high temperature antioxidant capacity, etc.
The silicon carbide semiconductor industry chain mainly includes the following links:
1.silicon carbide high -purity powder
2.single crystal substrate,
