About 4H-N SiC
SiC substrate refers to a wafer made of silicon carbide (SiC), which is a wide-bandgap semiconductor material that has excellent electrical and thermal properties.
SiC substrates are commonly used as a platform for the growth of epitaxial layers of SiC or other materials, which can be used to fabricate various electronic and optoelectronic devices, such as high-power transistors, Schottky diodes, UV photodetectors, and LEDs.
SiC substrates are preferred over other semiconductor materials, such as silicon, for high-power and high-temperature electronics applications due to their superior properties, including higher breakdown voltage, higher thermal conductivity, and higher maximum operating temperature.
SiC devices can operate at much higher temperatures than silicon-based devices, making them suitable for use in extreme environments, such as in automotive, aerospace, and energy applications.
