As an important kind of optical material, the sapphire has been widely used in many fields such as the fields of science and technology, national defense and civil industry. Due to the unique machining characteristics of the sapphire substrate, the application of IC wafer processing precision grinding and polishing technology can obtain ultra-precision nano-size precision substrate chips, which have been widely used in the areas of science and technology, national defense and civil industry, electronic technology and other fields.
LED chip is the largest application field of sapphire substrate. The sapphire substrate has also been widely used in the LED lighting industry, which brings an important impact on the development of the sapphire industry. Benefiting from the policy promotion and support, China's LED market has obtained great progress. LED lighting products are now widely used in many fields such as the industrial, commercial and household lighting areas. Driven by the growth of the downstream application market, LED lighting market scale is expanding rapidly.
The LED sapphire substrate is an essential part of the LED lighting chip, accounting for more than 50% cost of the chip. Led by the LED lighting market, the LED sapphire substrate market also expands rapidly. More than 76% of sapphire chips are used in LED chip substrate.
