Product Description

 

Our sapphire wafers are made of single crystal aluminum oxide (Al₂O₃) with a hexagonal lattice structure, commonly available in C-plane, A-plane, and R-plane orientations. With broad optical transparency from near-ultraviolet (190 nm) to mid-infrared, these wafers are ideal for optical components, infrared devices, high-strength laser windows, and mask materials. Sapphire’s high hardness, thermal stability, corrosion resistance, high melting point (2045°C), and excellent transparency make it a reliable material for demanding applications, though it requires precision processing.

For LED manufacturing, sapphire wafers are essential for high-quality GaN epitaxial growth, as their surface processing directly affects the brightness and uniformity of white, blue, and green LEDs. The minimal lattice mismatch between sapphire C-plane substrates and III-V/II-VI thin films ensures excellent alignment with high-temperature epitaxy processes, making sapphire wafers indispensable for advanced optoelectronic devices.
