Built for Extreme Performance:
Our N-type 3C-SiC substrates are meticulously engineered for next-generation high-frequency power components and automotive EV inverters. They dramatically outperform traditional silicon by offering extraordinary thermal stability (up to 1,600°C) and superior thermal conductivity (49 W/m·K). Manufactured to rigorous aerospace-grade international standards, these wafers guarantee unwavering reliability in the most demanding operational environments.

• Standard Formats: Available in 2", 4", 6", and 8" diameters.
• Bespoke Geometry: Custom sizing starts from micro-dimensions of 5×5 mm to client-specific layouts.

• Microvoid densities are strictly maintained below 0.1 cm⁻².
• Exceptional resistivity control (≤0.0006 Ω·cm) ensures maximum device yield and reliability.

• Optimized for intense fabrication steps like high-temperature oxidation and advanced lithography.
• Superior surface flatness achieved at λ/10 @632.8 nm.

Boasting a remarkable electron mobility of 1,100 cm²/V·s, our 3C-SiC significantly eclipses standard 4H-SiC (900 cm²/V·s), translating to minimal conduction losses. Its 3.2 eV wide bandgap empowers the substrate to handle massive voltage loads up to 10 kV.

With a thermal conductivity rating of 49 W/m·K, it effortlessly surpasses conventional silicon. This allows devices to operate securely across extreme temperature spectrums, from cryogenic -200°C up to blistering 1,600°C environments.

Highly impervious to aggressive acids, strong alkalis, and intense ionizing radiation, making it the material of choice for nuclear infrastructure and deep-space aerospace modules.
