Application of LED Sapphire Substrate

Application of LED Sapphire Substrate

As an important optical material, sapphire has been widely used in many fields such as science and technology, national defense, civil industry, etc. Due to the unique mechanical processing characteristics of sapphire crystal, ultra-precision nano-size substrate wafer can be obtained by using the precision grinding and polishing technology of IC wafer processing, which has been widely used in science and technology, national defense and civil industry, electronic technology, and many other fields.


It is suggested that the LED sapphire substrate has good mechanical, mechanical, chemical, optical, and thermal properties. As an important technical crystal, sapphire crystal has been widely used in many fields, such as transparent infrared window materials, substrates in microelectronics, laser substrates, optical elements, and other applications.


LED chip is as the first application field of sapphire substrate wafer, and the LED sapphire substrate chip has been widely used in the LED lighting industry, which has an important impact on the development of the sapphire industry. Thanks to policy promotion and support, China's LED market has made great progress. LED lighting products have been widely used in many fields such as industry, commerce, and home lighting. Driven by the growth of the downstream application market, the scale of China's LED lighting market is expanding rapidly.


LED sapphire substrate is an essential part of LED lighting chips, accounting for more than 50% of the chip cost. Driven by the LED lighting market, the market scale of sapphire substrate chip for LED has also increased rapidly, and more than 76% of sapphire wafers are used in LED chips.
