Semiconductor Wafer Inc. 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 produed as per SEMI
standards it has good surface finish Ra < 5A and high cleanliness ,
SWI 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. Contact us for for further information on
price & delivery time . |
