Description of 4H-SEMI SiC
4H-Semi SiC wafers refer to 4H-semi-insulating silicon carbide (SiC) wafers.
Such wafers are usually made by cutting and processing high-purity 4H-SiC crystals.
4H-SiC is a SiC crystal with a specific crystal structure, in which silicon (Si) atoms and carbon (C) atoms are arranged in a specific way to form a lattice structure.
4H-SiC wafers have attracted much attention due to their importance in the semiconductor industry.
4H-SiC has a wide range of applications in power electronics, RF and microwave devices, optoelectronic devices, and high-temperature and high-pressure applications.
Semi-insulating 4H-SiC wafers generally exhibit low carrier concentrations and high insulation properties, and are suitable for many high-power, high-frequency, and high-temperature applications.
These 4H-Semi SiC wafers are often used to manufacture various types of devices, such as power MOSFETs, power diodes, RF power amplifiers, photoelectric sensors, etc.
Their excellent performance, high voltage resistance, high thermal conductivity, and stability at high temperatures and high pressures make these wafers play a key role in various industrial and scientific research applications.
