Sapphire Single Crystal Substrate & Wafer
Sapphire Single Crystal Substrate : The double sided polished Sapphire Substrate made in China covers both the C plane.Its dimensions include 4 inches, 6 inches, 8 inches, and some special sizes. We can also provide customized services.The surface is treated by a DSP or SSP.Mainly used in semiconductor carriers or some optical applications. The main material for sapphire wafer is high purity single crystals Al2O3. The thickness is basically 1300 +/- 25 um.Its Bow and warp are all smaller than 25 microns.The C plane is basically maintained within (0001) off M (1-100) plane 0.2 +/- 0.05 degree. The packaging we use is a vacuum sealed container filled with nitrogen gas in a Class 100 environment, which is non polluting. Polishing can be done on one or both sides.The reverse side of SSP wafer was fine ground to Ra = 0.8 – 1.2 um. The raw materials we choose are of high quality, with sapphire crystal oriented along the c-axis and a thickness of 0.725 millimeters. They are used in semiconductor display boards and optics, and the SS and PS decolorization rates have reached 85%. There are many sizes available for you.
