As an important optical material, sapphire has been widely used in many fields such as science and technology, national defense and civil industry. Due to the unique machining characteristics of sapphire crystals, the precision grinding and polishing technology of IC wafer processing enables ultra-precision nano-precision substrate wafers, which have been widely used in science and technology, defense and civil industries, and electronic technology. And many other fields.

As the first application field of sapphire substrate wafers, sapphire substrate wafers have been widely used in the LED lighting industry and have an important impact on the development of the sapphire industry. Benefiting from policy promotion and support, China's LED market has made great progress. LED lighting products have been widely used in many fields such as industrial, commercial and home lighting. Driven by the growth of downstream application market, the scale of China's LED lighting market has expanded rapidly.

LED sapphire substrate wafers are an indispensable part of LED lighting chips, accounting for more than 50% of the cost of chips. Driven by the LED lighting market, the market for LED sapphire substrate wafers has also increased rapidly, exceeding 76%. The sapphire wafer is applied to the LED chip substrate. According to the scale analysis of the sapphire substrate wafer market in recent years, the sapphire substrate wafer market scale will reach 3.12 billion yuan, an increase of 5% year-on-year.
