• Sapphire substrate is the popular substrates for III-V nitrides, superconductor and magnetic epi film due to less mis-matched lattice and stable chemical and physical properties.
• Wafer size: 1" x 0.5" x 0.5 mm thick
• Orientation (0001) tolerance:+/-0.5 Deg.
• Polished surface: substrate surface is EPI polished via a special CMP procedure with RA < 8 A
• Package:Each wafer is packed in 1000 class clean room with 100 grade plastic bag with wafer container
