4inch Sapphire Wafer 200um Orientation C Axis Highly Applied for Semiconductor
Product Description:
Sapphire wafers are composed of aluminum oxide (Al₂O₃), in which three oxygen atoms are covalently bonded to two aluminum atoms. They exhibit a hexagonal lattice crystal structure and are commonly cut along the A-plane, C-plane, and R-plane orientations. Owing to their broad optical transparency range, sapphire wafers transmit light from the near-ultraviolet (190 nm) to the mid-infrared wavelengths, making them an ideal choice for optical components, infrared devices, high-power laser windows, and photomask materials. Sapphire wafers are renowned for their high acoustic velocity, high-temperature resistance, corrosion resistance, high hardness, excellent transparency, and high melting point (2045°C). They are a challenging material to process, but are widely used in optoelectronic devices.
