Does the LED industry's non-sapphire substrate improve the cost direction?

The high cost of LEDs makes it difficult to reduce the price in the market, which makes LED lighting difficult to spread to the average home. This is the biggest bottleneck in the LED industry. Therefore, the discussion on improving the cost of LEDs has not stopped. Recently, some experts have proposed new industrial thinking to improve LED cost and process. Among them, the new technology direction of non-sapphire substrate solution has caused the LED market to be shocked. Due to cost and electrical considerations, many large manufacturers have begun to use non-sapphire substrate technology to create LEDs. Well-known manufacturers include TSMC SSL, and the combination of Bridgelux and Toshiba. In addition, US equipment giant Veeco is quite optimistic about the progress of Gan-on-Si, and it is expected that 8-inch equipment will be the new focus of the future market. In addition to optimistic about Gan-on-Si, German equipment manufacturer Aixtron also introduced MOCVD equipment to build power supply units with higher temperature processes, which have been purchased and cut into the power supply market. Japanese equipment factory Dayang Risin also launched Gan-on-Si's MOCVD equipment products and highlighted the niche market. In addition, Cree also introduced LEDs that do not use sapphire substrate technology, and build LEDs based on SiC, demanding high performance. South Korea's LED factory Seoul Semiconductor has introduced the latest nPora technology, which is one of the results of cooperation with the father of Blu-ray LED, Nakamura Shuji. With Gan-on-Gan technology, there are relatively few manufacturers of such Gan substrates, but they have already come out one after another. The size of the goods is more suitable for creating LED chips than traditional sapphire substrates. In fact, LEDs built on these new non-sapphire substrates are new technologies, so the initial cost should not be effectively reduced. However, such a development direction is basically correct, and the non-sapphire substrate solution is also expected to become the next feasible new path for the LED industry.
