Sapphire Wafer 2inch C Axis 100um DSP Customized Design Available
Product Description
Sapphire Wafer is a monocrystalline substrate made from high-purity aluminum oxide (Al₂O₃) crystal, widely used in fields such as semiconductors, optoelectronics, lasers, and LEDs. It possesses excellent physical, chemical, and optical properties, particularly in high-temperature, high-frequency, and high-power applications, ensuring the stability and reliability of devices. The manufacturing process of sapphire wafers typically uses techniques such as the Verneuil process, ensuring extremely high purity and uniform crystal structure.

Product Highlights:
*High Hardness: With a Mohs hardness of 9, second only to diamond, a sapphire wafer has excellent scratch - resistance and wear - resistance.
*High Transmittance: A sapphire wafer has excellent optical transmittance, especially in the ultraviolet - to - infrared band, which ensures the efficient transmission and low loss of photon energy.
*Good Thermal Conductivity: A sapphire wafer thermal conductivity is as high as 42 W/m·K (at room temperature), and it also shows excellent thermal stability at high temperatures, which can effectively dissipate heat.
*Chemical Stability: A sapphire wafer has excellent corrosion - resistance and can maintain the integrity of the material for a long time in extreme environments such as acids and alkalis.

F&Q:
Q: What is a sapphire wafer?
A: A sapphire wafer is a circular thin slice made of sapphire material, which is widely used in the manufacturing of semiconductors and optical devices.
Q: What size are sapphire wafers?
A: 2inch, 3inch, 4inch, 6inch, 8inch, 12inch.
Q: How to cut a sapphire wafer?
A: Cutting a sapphire wafer requires specialized methods due to its extreme hardness (9 on the Mohs scale, second only to diamond) and brittleness. The core approach relies on abrasive-based or laser-based techniques to achieve precise, low-damage cuts.
