2. About SiC Ingot Progress
At present, the standard method for preparing SiC ingots in the world is the seed crystal sublimation method. The principle is to use induction or resistance heating to heat the closed crucible system, place the solid mixture as the growth source at the bottom of the crucible at a higher temperature, and fix the seed crystal on the top of the crucible at a lower temperature. The source for SiC ingot growth sublimates and decomposes at low pressure and high temperature to produce gaseous substances, driven by the pressure gradient formed by the temperature gradient between the growth source and the seed crystal. These gaseous substances are naturally transported to the low temperature seed crystal position, and SiC wafer ingot growth due to the generation of supersaturation.
