sapphire wafer

Worldhawk provides sapphire wafer with complete orientation options including C plane , A plane , R plane and M plane , in diameter range  from 1" to 4" , square substrate is also available as well , size from 10 x 10 mm to 100 x 100 mm . Substrate are produced as per SEMI standards, it has good surface finish Ra < 5A and high cleanliness, we can offer epi ready grade sapphire wafer for your epitaxial growth. Sapphire wafer are produced by Czochralski method, due to it's high strength, high anti-corrosion high anti-abrasion, low dielectric loss and good electrical insulation, single crystal  sapphire wafer plays an increasingly important role as a material for blue LED and high Tc superconductor and microwave applications.
