LED industry bottlenecks sapphire in the end also treasure not treasure?

The high cost of LED, resulting in the price of the market is difficult to have a substantial reduction, which makes it difficult to spread the popularity of LED lighting to ordinary homes, which is currently the biggest bottleneck encountered in the LED industry. Therefore, in order to improve the cost of LED discussion, has not stopped.

In a recent LED seminar, the experts proposed new thinking, improve LED cost and the industrial process in which comprehensive toward the non sapphire substrate (non-sapphire substrate solution) scheme of the new technology, caused the shock of LED market.

Because of the cost and power considerations, many companies began to try to use non sapphire substrate technology to build LED, well-known manufacturers including TSMC solid-state lighting (TSMC SSL), and BridgELux of the US and Japan's Toshiba (Toshiba) combination. In addition, the United States equipment manufacturer Veeco for the progress of Gan-on-Si is quite optimistic, is expected to 8 inches of equipment is the new focus of the future market. German equipment manufacturer Aixtron in addition to optimistic about Gan-on-Si, also introduced the use of MOCVD equipment, with a higher temperature process to build power supply devices, manufacturers have been purchased and cut into the power market. Japanese equipment factory also launched Gan-on-Si Dayang acid MOCVD equipment products, and emphasizes the niche market.

In addition, Cree also launched the sapphire substrate technology without LED, based on the SiC to build LED, demanding efficient. South Korea LED semiconductor factory in Seoul launched the new nPora technology, which is one of the father of Nakamura Shuji and the blue LED collaboration, using Gan-on-Gan technology, the Gan substrate manufacturers is relatively small, but there have been the size of shipments, than the traditional sapphire substrate is more suitable to build LED chip.

In fact, through these new non sapphire substrate to build LED, as a result of new technologies, so the initial cost should not be able to effectively reduce significantly. But this direction of development is basically correct, non sapphire substrate program is also expected to become a viable new path in the LED industry.
