Wat are 150mm Sapphire Wafers Used For?

150mm sapphire wafers are commonly used in a variety of high-tech applications due to their unique properties, including high thermal conductivity, chemical stability, and excellent optical clarity. Here are some key uses:

  1. LED Manufacturing: Sapphire wafers serve as the substrate for growing gallium nitride (GaN) layers, which are essential for producing blue and white LEDs.

  2. Semiconductor Devices: They are used as substrates in the fabrication of various semiconductor devices, including integrated circuits (ICs) and power electronics, due to their excellent insulating properties and high-temperature stability.

  3. Optoelectronics: Sapphire wafers are used in optoelectronic devices such as laser diodes, photodetectors, and other components that require a transparent and durable substrate.

  4. RFICs (Radio Frequency Integrated Circuits): Sapphire's high dielectric constant and low loss tangent make it suitable for RFIC applications, where it supports high-frequency operations with minimal signal loss.

  5. Watch Crystals and Windows: Due to its hardness and scratch resistance, sapphire is often used for watch crystals and other durable, transparent windows in scientific and industrial equipment.

  6. Optical Components: Sapphire wafers are used in the production of optical components such as lenses, prisms, and windows, particularly in harsh environments where durability is crucial.

  7. MEMS Devices: Micro-Electro-Mechanical Systems (MEMS) devices often use sapphire substrates for their mechanical strength and stability.

These applications leverage sapphire's robustness, thermal properties, and optical clarity, making it an indispensable material in various advanced technological fields.
