Sapphire wafer
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.
