4H-N Type SiC Substrate 10×10mm Small Wafer Customizable Shape & Dimensions
The SiC 10×10 small wafer is a high-performance semiconductor product developed based on third-generation semiconductor material silicon carbide (SiC). Manufactured using Physical Vapor Transport (PVT) or High-Temperature Chemical Vapor Deposition (HTCVD) processes, it offers two polytype options: 4H-SiC or 6H-SiC. With dimensional tolerance controlled within ±0.05mm and surface roughness Ra < 0.5nm, the product is available in both N-type and P-type doped versions, covering a resistivity range of 0.01-100Ω·cm. Each wafer undergoes rigorous quality inspections, including X-ray diffraction (XRD) for lattice integrity testing and optical microscopy for surface defect detection, ensuring compliance with semiconductor-grade quality standards.
