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) crystals have unique physical and electronic properties. SiC-based devices are widely used for short-wavelength opto-electronic, high-temperature, and radiation-resistant applications. High-power and high-frequency devices made from SiC outperform Si- and GaAs-based devices.
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 for fabricating 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 ratings, lower parasitic resistances, smaller size, and reduced cooling requirements due to high-temperature capability.
Silicon carbide (SiC) wafers provide excellent electrical and thermal properties, including low thermal expansion and superior hardness. They perform well at high temperatures and exhibit high resistance to corrosion, erosion, and oxidation. Additionally, SiC wafers are shinier than diamonds or cubic zirconia.
While Silicon carbide (SiC-4H) – 4H wafers offer 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.
