Application Properties & Features of Sapphire Wafers
1. Excellent Optical Transparency
The sapphire wafer’s high purity translates into superior optical clarity across the ultraviolet, visible, and near-infrared spectrum. Its high transmittance (> 90%) makes it ideal for use in optical components such as windows, lenses, and laser substrates. The C-plane orientation provides uniform optical properties, essential for precise light manipulation.
2. Mechanical Durability
With a hardness of Mohs 9, sapphire wafers are among the hardest materials available, offering exceptional scratch resistance and mechanical strength. The anti-scratching coating further enhances surface durability, minimizing surface damages during handling, processing, and assembly.
3. High Thermal and Chemical Stability
This sapphire wafer can withstand extreme temperatures up to 2000°C with minimal distortion, making it suitable for high-temperature applications like LED epitaxy and sensor fabrication. Its chemical inertness ensures resistance to corrosive environments, prolonging component lifespan.
4. High Purity and Crystalline Quality
Manufactured through controlled crystal growth methods (Kyropoulos or similar), the wafer’s purity (99.99%) reduces impurity-related defects, improving device performance and yield. The precise C-plane orientation facilitates epitaxial layer growth with minimal defects, critical for semiconductors like GaN, LEDs, and laser diodes.
