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.
