Why has silicon carbide (SiC) become the most important material for third-generation semiconductors?

In the semiconductor industry, high-purity graphite is primarily used for heaters, support crucibles, thermal insulation shields, and other components. The utilization of high-purity graphite for these parts takes full advantage of its high-temperature resistance. Especially during the growth process of SiC crystals, impurities in graphite are a key determinant of crystal quality. Our company's graphite purity can reach below 5 PPMW, meeting customers' demands for high-purity graphite in production environments.
