Substrates and Wafers for GaN Thin Film Growth
Silicon Carbide (SiC) is a semiconductor containing silicon and carbon. Sic has thermal conductivity and great energy to penetrate electric field, there is currently much interest in its use as a semiconductor material in electronics, where its high thermal conductivity, high electric field breakdown strength and high maximum current density make it more promising than silicon for high-powered devices. SiC also has a very low coefficient of thermal expansion (4.0 × 10-6 /K) and experiences no phase transitions that would cause discontinuities in thermal expansion. The main application area of it are high frequency power electron devices (Schottky diodes, MOSFET , JFET, BJT, PIN diodes, IGBT) and optoelectronic devices (it is widely applied in backing material of blue LED).
Hangzhou Shalom EO offer the custom SiC wafers, they are widely used in the LED solid-state lighting and high-frequency devices, in applications of fields and extreme environmental applications such as aerospace, military industry, and nuclear energy.
