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.
