About 4H-SEMI SiC
Description of 4H-SEMI SiC
Silicon Carbide (SiC) is a versatile semiconductor renowned for its performance in high-power and high-frequency applications.
Its wide bandgap enables efficient operation at high voltages and temperatures, making it suitable for power electronics, RF devices, and harsh environments.
SiC is integral to industries such as automotive and energy due to its reliability and efficiency.
Advanced manufacturing methods, like Chemical Vapor Deposition (CVD) and Physical Vapor Transport (PVT), ensure high-quality, durable components.
SiC's unique properties also make it ideal for short-wavelength optoelectronics, high-temperature environments, radiation resistance, and demanding electronic systems.
ZMSH offers a range of SiC wafers, including 6H and 4H types, no matter N type, SEMI type or HPSI type, ensuring high quality, stable supply, and cost-effectiveness through large-scale production processes.
