Sapphire substrate accounts for 96.3% of the global LED market! Data will also rise

According to IHS's latest research shows that in 2015 96.3% of the world's LED production using sapphire substrate, the data is expected to rise to 96.7% by the year of 2020.

2015 thanks to falling prices, sapphire application market has been boosted. Especially the 4 inch wafer to occupy a market share of 55% in 2015 (by region, of which 9.9% is the capacity), Seoul Dachang Samsung Semiconductor, EPISTAR segmentation; 6 inch wafer production capacity continued to increase, mainly in OSRAM, Lumileds, LG and CREE and other manufacturers of chemical is preferred.

Sapphire substrate has accounted for 96.3% of the global LED Market

IHS said, almost all of the top LED vendors -- including Nichia, OSRAM, Lumileds company, Seoul optoelectronic semiconductor, EPISTAR and Sanan optoelectronics are using sapphire wafer. Comprehensive analysis of the global LED substrate market, Plessi, latticepower and Samsung mainly use silicon substrate, but the technology started late, the industry is small in scale, low market share; CREE company mainly adopts the silicon carbide substrate, but because of the cost, plus the patent monopoly, almost no other companies involved in. Nakamura Shuji led the company's Soraa is known to use the bulk gallium nitride (GaN) substrate, the substrate material is LED good, but more expensive than sapphire, and the production size is limited, can not be used. Therefore, the rapid development of sapphire substrate, occupy the mainstream market.

Sapphire is expected to continue to maintain a leading position in the field of LED substrate manufacturing. Due to the low yield, lattice mismatch and sapphire wafer prices and other reasons, the current high silicon substrate can not successfully replace the sapphire substrate. Other substrates, including silicon, silicon carbide and gallium nitride, are not expected to gain much in the next few years.

At present, sapphire as the LED substrate has two main advantages: first, most of the existing industry expertise and production equipment and the production of sapphire is matching; second, sapphire low cost high availability, can produce cheap products LED. Of course, sapphire substrates also have many disadvantages. Such as lattice mismatch, thermal mismatch, and poor electrical and thermal conductivity, but these are not enough to affect the market position of sapphire substrate. Only when there is a better performance in the future, the lower the price of the substrate products, the existing market structure is likely to change.
