4H-N 2/3/4/6/8/12 Inch Silicon Carbide (SiC) Substrate – Prime/Dummy/Research Grade
This product series provides high-purity Silicon Carbide (SiC) substrates in multiple diameters (2", 3", 4", 6", 8", and 12"), designed for advanced semiconductor, power electronics, and optoelectronic applications. Available in Prime (device-grade), Dummy (process-testing), and Research (experimental) grades, these substrates feature excellent thermal conductivity (> 400 W/m·K for SiC), high breakdown voltage, and superior chemical stability.
The Prime Grade ensures ultra-low defect density, making it ideal for high-performance devices like MOSFETs, Schottky diodes, and RF components. The Dummy Grade offers cost-effective solutions for process optimization, while the Research Grade supports academic and industrial R&D in wide-bandgap semiconductor technologies.
With customizable specifications (doping, thickness, polishing), these substrates meet the stringent demands of power electronics, 5G communications, and electric vehicle (EV) applications.
