High Resistance Single Side Polished LED Sapphire Wafer with BOW 10um
Product Description:
Sapphire Wafer is a kind of sapphire slice that has been precision cut from a sapphire boule to the required dimensions. It is widely used for various applications in the optoelectronics, electronics, and semiconductor industries. Sapphire Wafer has excellent thermal conductivity, high thermal shock resistance, high dielectric strength, and excellent optical properties, making it ideal for high reliability applications. Its mechanical properties are superior to those of quartz and optical glass. The features of Sapphire Wafer include bow & warp of ≤20μm, diameter of 2inch-8inch, perpendicularity of ≤3 Arc Min, TTV of ≤3μm and single side polished surface quality.
