What Are 150mm Sapphire Wafers Used For?

150mm sapphire wafers are selected for demanding applications that require mechanical strength, thermal stability, chemical resistance, optical clarity, and electrical insulation.

  1. LED Manufacturing: Sapphire is widely used as a substrate for growing gallium nitride (GaN) films for blue, white, and UV LED devices.

  2. Semiconductor Device Fabrication: Sapphire wafers support semiconductor device manufacturing where insulation, thermal resistance, and dimensional stability are important.

  3. RF and Microwave Devices: Sapphire substrates are used in RFIC and microwave applications because of their low electrical loss, high insulation resistance, and stable dielectric properties. Learn more about dielectric constant.

  4. Optoelectronics: Sapphire wafers are used for photodetectors, laser diodes, optical sensors, and transparent substrates that require strength and optical transmission.

  5. MEMS Devices: MEMS researchers use sapphire substrates when high mechanical strength, chemical durability, and thermal stability are required.

  6. Optical Windows and Components: Sapphire is used for durable windows, lenses, watch crystals, prisms, and harsh-environment optical parts because it is hard, scratch resistant, and transparent.
