Thickness 1.0mm Sapphire Wafers Substrate Ssp Dsp C-Plane Single Crystal 99.999% Al2O3

Sapphire wafers are known for their exceptional strength and durability in harsh environments, making them highly desirable for a wide range of applications. In fact, sapphire is one of the hardest and most scratch-resistant materials available, with a Mohs hardness of 9, second only to diamond.

In comparison to other materials, sapphire wafers are much stronger and more durable than most metals, plastics, and glasses, particularly in high-temperature and high-pressure environments. Sapphire can withstand temperatures up to 2000°C and has a thermal conductivity that is three times higher than that of stainless steel, which makes it particularly useful in high-temperature applications.

Furthermore, sapphire is highly resistant to corrosion and chemical attack, making it well-suited for use in harsh chemical environments. It is also highly resistant to radiation damage and has excellent optical properties, making it ideal for use in high-energy physics experiments and space applications.

Overall, sapphire's exceptional strength, durability, and resistance to harsh environments make it a highly attractive material for a wide range of industrial, scientific, and defense applications.

The Manufacturing process of 300mm sapphire substrate:

1. Crystal growth: The Sapphire material is grown using the KY or the CZ method.
2. Cutting: The sapphire crystal is cut into thin wafers using a diamond saw.
3. Grinding and polishing: The wafer is ground and polished to achieve a smooth and flat surface.
4. Cleaning: The wafer is cleaned using a combination of chemicals and ultrasonic rinsing.
5. Drying: The wafer is dried using a spin dryer or a Nitrogen gun.
