Fields of Application for Silicon Carbide (SiC-4H) – 4H Wafer
Silicon carbide (SiC) is a rare compound of silicon and carbon that is synthetically produced.
Silicon carbide (SiC) wafers possess excellent electrical and thermal properties, including low thermal expansion, superior hardness, and high performance at elevated temperatures. They also exhibit strong resistance to corrosion, erosion, and oxidation, and have a surface shinier than diamonds or cubic zirconia.
Silicon carbide (SiC) crystals exhibit unique physical and electronic properties. SiC-based devices are widely used in short-wavelength opto-electronics, high-temperature, and radiation-resistant applications. High-power and high-frequency electronic devices fabricated with SiC outperform those based on Si or GaAs.
SiC-based devices exhibit low lattice mismatch with III-nitride epitaxial layers, high thermal conductivity, and are suitable for combustion monitoring and UV detection. They can operate under extreme conditions, including high temperature, high power, and high radiation environments.
SiC is used in the fabrication of very high-voltage and high-power devices such as diodes, power transistors, and high-power microwave devices. Compared to conventional Si devices, SiC-based power devices offer faster switching speeds, higher voltage handling, lower parasitic resistance, smaller size, and reduced cooling requirements due to their high-temperature capability.
While Silicon carbide (SiC-4H) – 4H wafers provide superior electronic properties, Silicon carbide (SiC-6H) – 6H wafers are easier to prepare and more extensively studied.
Silicon carbide (SiC) wafers are used for hybrid and electric vehicles.
Silicon carbide (SiC) wafers are used for green energy generation.
Silicon carbide (SiC) wafers are used for LEDs.
Silicon carbide (SiC) wafers are used for many other emerging markets.
