Sapphire Wafer 12'' Dia 250mm±0.5mm Thickness 1000 Um C-Plane DSP

12" Sapphire Wafer 250mm Diameter (±0.5mm) 1000µm Thickness C-Plane

This 12-inch (250mm) sapphire wafer delivers industry-leading precision (±0.5mm diameter, 1,000µm thickness) and ultra-high purity (99.99%), optimized for advanced semiconductor and optoelectronic applications. The C-plane (0001) orientation ensures exceptional epitaxial growth quality for GaN-based devices, while its large diameter maximizes production efficiency for high-volume manufacturing. With superior thermal stability (>2,000°C melting point), optical transparency (85%+ from UV to mid-IR), and mechanical robustness (9 Mohs hardness), this wafer is ideal for power electronics, LEDs, laser systems, and cutting-edge quantum technologies.
