Sapphire wafers are made from crystalline sapphire, which is a form of aluminum oxide (Al2O3). Sapphire is a durable and hard material known for its exceptional optical, mechanical, and thermal properties.
These wafers are used in various industries due to sapphire's advantageous characteristics, including high hardness, scratch resistance, high melting point, chemical inertness, excellent transparency in the visible to near-infrared spectrum, and thermal conductivity.
Sapphire wafers find applications in:
Optics and Photonics: Due to their excellent transparency, sapphire wafers are used in optical components like lenses, windows, and substrates for LEDs (Light-Emitting Diodes) and laser systems.
Semiconductor Industry: They serve as a substrate for manufacturing electronic devices, particularly in the production of LEDs, where sapphire acts as a base for gallium nitride (GaN) epitaxy to create high-performance LED chips.
Specialized Applications: Sapphire wafers are used in various specialized applications such as watch crystals, protective covers for optical sensors, and high-precision scientific instruments due to their durability and optical clarity.
