1. Sapphire has a high optical transmittance, so it is widely used as microelectronic tube dielectric material, ultrasonic conduction element, waveguide laser cavity, and other optical elements, as window materials for infrared military devices, space vehicles, high-intensity lasers and optical communications.

2. Sapphire has high rigidity, high strength, high working temperature, abrasion resistance, corrosion resistance characteristics, so sapphire substrate is often used in harsh environments, such as boiler water gauge (high-temperature resistance), commodity bar code scanner, bearing, and other precision manufacturing (wear resistance), coal, gas, well detection sensors and detector windows (anti-corrosion).

3. Sapphire has the characteristics of electrical insulation, transparency, good thermal conductivity, and high rigidity, so it can be used as the substrate material of integrated circuits, such as LED and microelectronic circuits, ultra-high-speed integrated circuit.

    Sapphire application 

    • 1. Semiconductor LED industry (MOCVD epitaxial GaN substrate)
    • In general, C-plane sapphire is needed in this area. R-plane or M-plane mainly used to grow non-polar/semi-polar plane epitaxial layers to improve the luminescence efficiency.
    • 2. The growth of III-V or II-VI compound semiconductors.
    • 3. Microelectronic IC applications especially Very High-Speed Integrated Circuit, SOS
    • Generally, it is a silicon heteroepitaxial deposition on R-plane sapphire.
    • 4. Hybrid microelectronics
    • Hybrid microelectronics products are mainly HIC and MCM. It has high requirements on the substrate, while sapphire substrates' characteristics such as stable dielectric constant and low dielectric loss make sapphire wafer the most commonly used substrate for HIC and the main substrate for MCM. Generally, the A-plane sapphire wafer is needed.
