HPSI High Purity Semi-insulating SiC Wafers – 2/3/4/6/8 Inch Prime/Dummy/Research Grade
HPSI (High Purity Semi-insulating) Silicon Carbide (SiC) wafers are advanced semiconductor substrates designed for high-frequency, high-power, and high-temperature applications. Available in 2-inch, 3-inch, 4-inch, 6-inch, and 8-inch diameters, these wafers are offered in Prime (production-grade), Dummy (process-testing), and Research (experimental) grades to meet diverse industrial and academic needs.
The Prime Grade wafers feature ultra-low defect density and high resistivity, making them ideal for RF devices, power amplifiers, and quantum computing applications. The Dummy Grade provides cost-effective solutions for process optimization in semiconductor fabrication, while the Research Grade supports cutting-edge material studies and prototype development.
With superior thermal conductivity (> 490 W/m·K) and a wide bandgap (3.2 eV), HPSI SiC wafers enable next-generation electronics for 5G communications, aerospace, and electric vehicle (EV) systems.
