8inch 4H-N type SiC Wafer's abstract

 

The 8-inch 4H-N type Silicon Carbide (SiC) wafer represents a cutting-edge material widely used in power electronics and advanced semiconductor applications. Silicon carbide, particularly the 4H polytype, is highly valued for its superior physical and electrical properties, including a wide bandgap of 3.26 eV, high thermal conductivity, and exceptional breakdown voltage. These characteristics make it ideal for high-power, high-temperature, and high-frequency devices.

 

The N-type doping introduces donor impurities such as nitrogen, enhancing the wafer's electrical conductivity and enabling precise control of its electronic properties. This doping is essential for fabricating advanced power devices like MOSFETs, Schottky diodes, and other high-efficiency components. The 8-inch wafer size marks a significant milestone in SiC wafer technology, offering increased yield and cost-effectiveness for large-scale production, meeting the demands of industries such as electric vehicles, renewable energy systems, and industrial automation.
