Sapphire wafers are thin discs made from a single crystal of sapphire, a high-performance material with excellent mechanical, thermal, and optical properties. Sapphire wafers are commonly used in a wide range of applications, such as in the production of LEDs, high-temperature and high-pressure sensors, microelectronics, and other optical components.

The manufacturing process of sapphire wafers involves a complex and precise process of growing, cutting, and polishing the sapphire crystal. First, a seed crystal is placed in a crucible with molten alumina, and the crystal is slowly pulled upwards while rotating. This process allows a single crystal to form and grow vertically, with a specific orientation and lattice structure.

After the crystal is grown, it is then cut into thin discs using a diamond saw or laser cutting. These discs are then polished to a high degree of smoothness using a series of abrasives and chemical treatments, resulting in a flawless surface finish. The final wafers are then inspected and tested for quality and performance.

Sapphire wafers have a range of advantages over other materials, including high hardness, excellent optical clarity, high thermal conductivity, and high resistance to chemicals and corrosion. These properties make sapphire wafers ideal for a wide range of demanding applications, where precision, durability, and reliability are crucial.
