Sapphire wafer is an important material widely used in semiconductor, optoelectronic and LED manufacturing.
Sapphire wafer has excellent physical and chemical properties, such as high hardness, excellent thermal conductivity and good optical transmittance, especially in the ultraviolet to near-infrared band.
In the manufacturing process, sapphire wafers are usually prepared by melt growth method (such as Czochralski method). This method can produce high-purity, low-defect sapphire crystals to ensure the quality and performance of wafers. In electronic devices, sapphire as a substrate can effectively improve the stability and life of the device.
The 4-inch sapphire wafer is one of the common specifications in the current market. It is usually used to grow semiconductor materials such as gallium nitride (GaN) to manufacture high-performance light-emitting diodes (LEDs) and high-frequency electronic devices.
In addition, sapphire wafers are also widely used in high-precision optical components and integrated circuit substrates due to their stable crystal structure and high temperature and corrosion resistance.
With the advancement of technology, the application of 4-inch sapphire wafers continues to expand, especially in the fields of high-power electronics and photoelectric conversion. In the future, the development and application of sapphire materials will continue to promote the development of related industries and meet the needs of higher performance.
