The Jiangfengyi team of Nanchang University successfully developed the silicon substrate LED technology, making China the third country in the world to master the independent intellectual property rights technology of blue LED after Japan and the United States. This high-tech and successful industrialization won the first prize of the 2015 National Technology Invention Award, and the silicon substrate era came. At the same time, silicon substrate LEDs are also facing the cost advantage and technical difficulty. Among them, the biggest "blocker" is derived from the thermal mismatch and lattice mismatch of silicon and gallium nitride materials. However, at this time, LED people should be more interested in ideals and hopes. I believe that in the near future, the Chinese era of the global LED industry will come.
Ideal
Silicon substrate technology opens up new world of industry
In three cents, China has one. The Jiangfengyi team of Nanchang University successfully developed the silicon substrate LED technology, making China the third country in the world to master the independent intellectual property rights technology of blue LED after Japan and the United States. This high-tech and successful industrialization won the first prize of the 2015 National Technology Invention Award.
Indeed, when many people still indulge in the "loss of running" and "price war" of the LED industry, when they sigh, there are already a group of small partners in the industry who stand up and down-to-earth and use their own innovation to get out. Exclusive road of your own. The "One Belt, One Road" strategy promotes the "supply-side reform". The policies promulgated by the state have not given the LED industry a favorable and confidence. In the first quarter of this year, the brilliant data of many LED listed companies also confirmed the fact that the industry is rapidly recovering.
"Rebuilding industry confidence, open cooperation, and promoting positive energy" will become the theme of 2016·LED. Use subtraction to remove impetuousness and utilitarianism in the industry; use addition, gather people into fire, and combine wood into forest. This will be something that everyone in the LED industry should do. Please give a little time, maybe, not long after, the opportunity for the Chinese to shape the global LED industry is coming...
New pattern
How do emerging technologies pass the test?
All along, the LED chip substrate market, sapphire and silicon carbide in two directions "two worlds", but this pattern with the first prize of the National Technology Invention Award last year, the silicon substrate era came.
Nowadays, the LED chip substrate market, sapphire (the vast majority of manufacturers adopt solutions) and silicon carbide (mainly used by manufacturers as CREE) still occupy most of the country, but many companies have invested in the research and development of silicon substrate technology. produce.
For example, Toshiba purchased Puri's technology and quickly cut into the silicon substrate. Samsung announced that the next technology route and products are silicon substrate chips. China's Jingneng Optoelectronics, the “flag†of silicon substrate technology in Jiangxi Province, has become the world's first high-power, high-performance silicon substrate LED chip company.
However, the current unavoidable fact that the large-scale promotion of silicon substrate LEDs means that most LED chip companies may withdraw from the market. Therefore, for the sake of profit, some LED chip companies often amplify silicon lining when introducing products to customers. The shortcomings of the bottom LED are reasonable. At the same time, any thing inevitably has its own shortcomings. The silicon substrate LED is also facing the test of cost advantage and technical difficulty. Among them, the biggest "roadblocker" is derived from the thermal mismatch and lattice loss of silicon and gallium nitride materials. Match.
