Product Description

Sapphire is a material of a unique combination of physical, chemical and optical properties, which make it resistant to high temperature, thermal shock, water and sand erosion, and scratching. It is a superior window material for many IR applications from 3µm to 5µm. C-plane sapphire substrates are widely used to grow III-V and II-VI compounds such as GaN for blue LED and laser diodes, while R-plane sapphire substrates are used for the hetero-epitaxial deposition of silicon for microelectronic IC applications.

Applications

2-inch A-plane single crystal sapphire wafer substrates, composed of Al2O3 (aluminum oxide), are widely used in various advanced technological applications due to their excellent mechanical, thermal, and optical properties. The A-plane orientation of sapphire is particularly suitable for epitaxial growth of certain semiconductor materials, making it a popular choice in industries like microelectronics, photonics, and optoelectronics.

In microelectronics, these substrates are often used for fabricating high-frequency and high-power electronic devices due to their superior thermal conductivity and dielectric strength. In optoelectronics, A-plane sapphire wafers serve as a key material for producing LEDs and laser diodes, where the crystal's transparency and resistance to high temperatures are crucial. Additionally, in photonics, sapphire substrates are utilized in optical windows and components due to their high transmission rates for visible and infrared light. Their chemical inertness and hardness also make them valuable in harsh environments, where durability is essential.
