The Square Sapphire Substrate (SSP) is made from high-purity (>99.99%) single crystal Al₂O₃, offering excellent mechanical strength, thermal stability, and optical transparency. With C-plane (0001) orientation and single-side polished (SSP) surface, it is ideal for epitaxial growth, GaN-based LED production, optical components, and high-temperature or vacuum applications.
