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 mechanical processing characteristics of sapphire crystal, the precision grinding and polishing technology of IC wafer processing can obtain ultra-precise nano-sized precision substrate wafers, which have been widely used in many fields such as science and technology, national defense and civil industry, and electronic technology.

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

Sapphire substrate wafers for LED are an essential part of LED lighting chips, accounting for more than 50% of the chip cost. Driven by the LED lighting market, the market size of sapphire substrate wafers for LED is also rapidly increasing, with more than 76% of sapphire wafers used in LED chip substrates. GGII believes that the market size of sapphire substrate wafers will reach 3.12 billion yuan in 2019, an increase of 5% year-on-year, according to the analysis of the market size of sapphire substrate wafers in recent years.

Through long-term tracking of domestic LED epitaxial wafer and chip manufacturing enterprises, GGII has selected the TOP 10 Chinese sapphire (2, 4, 6-inch) substrate wafer companies in 2019 by integrating various factors such as market share, product quality, R&D capability, brand reputation, and service capability.
