Premium 12inch Sapphire Wafer for High Quality Lighting and Consumer Electronics Industries

Premium 12inch Sapphire Wafer for High Quality Lighting and Consumer Electronics Industries

Introduction of Sapphire Wafers:

   Sapphire wafers are primarily used in specialized fields such as light-emitting diode (LED) manufacturing. Sapphire possesses characteristics such as high hardness, high melting point, and excellent electrical insulation. Its hardness is second only to that of diamond, which makes sapphire wafers difficult to process, but also ensures exceptional stability and durability during use. Sapphire exhibits excellent optical transparency, particularly in the ultraviolet to near-infrared wavelength range, giving it broad applications in the field of optics. In LED manufacturing, sapphire wafers serve as substrate materials, providing a high-quality crystal growth environment that helps improve the luminous efficiency and stability of LEDs.The 12-inch sapphire substrate is an ultra-large single-crystal wafer made from high-purity aluminum oxide (Al₂O₃), with a diameter of 300 millimeters (12 inches). These substrates represent a major advancement in sapphire crystal growth and wafer processing technology, enabling high-throughput manufacturing for next-generation applications such as micro-LED displays, radio-frequency (RF) devices, power electronics, and optical components.

Applications of Sapphire Wafers:

LED Lighting and Displays: Sapphire wafers are the core substrate material used in LED chip manufacturing. They provide an ideal lattice-matching environment for the growth of light-emitting materials such as gallium nitride (GaN), thereby enhancing luminous efficiency and operational stability.

Q&A:

Q: What is a sapphire wafer?

A: A sapphire wafer is a single-crystal substrate made from aluminum oxide (Al₂O₃). It’s one of the hardest, most thermally stable, and optically transparent materials used in the semiconductor and optoelectronics industries.

Q: What is the difference between sapphire and silicon wafers?

A: sapphire wafers and silicon wafers are both key materials in the semiconductor industry, but they serve very different purposes because their physical, electrical, and optical properties are fundamentally distinct. Sapphire wafers are used where optical clarity, insulation, and durability are needed — such as in LEDs, RF, and optics.

Silicon wafers are used where electronic conductivity and integration are needed — such as in microchips, CPUs, and sensors.

Q: What size are sapphire wafers?

A: Sapphire wafers typically range from 2 to 12 inches in diameter, with thicknesses between 100 µm and 1.6 mm, depending on the device type, application, and polishing level.
