On January 8th, the silicon substrate LED technology completed by Professor Jiang Fengyi of Nanchang University won the first prize of the 2015 National Technology Invention Award, which proves that China attaches importance to the independent innovation of silicon substrate LED technology, and also marks China's LED. The industry will usher in new development opportunities. Silicon substrate LED technology has changed the global LED industry landscape. With the technological advantages and industrial base, Jiangxi will undoubtedly make the pace of Nanchang Optical Valley faster and more stable. Silicon substrate becomes the world's third blue LED technology. The preparation of high-efficiency GaN-based LEDs on silicon has always been the goal of the academic world. However, due to the large lattice mismatch and thermal mismatch between silicon and GaN, the epitaxial film crack, the poor crystal quality, and the low light-emitting efficiency caused by the opacity of the substrate have not been solved for a long time, which has led the industry to believe that it is on silicon. It is impossible to prepare high-efficiency GaN-based LEDs, and the GaN-based LED route on silicon substrates is almost sentenced to death. However, after more than 3,000 experiments, the technical research and development team led by Professor Jiang Fengyi of Nanchang University finally took the lead in solving the world problem in the world. Dr. Fu Wei, researcher of the project team, said that the advantages of silicon substrate LED technology are obvious. It can be combined with large-scale, low-cost silicon substrate and automated technology to achieve a significant reduction in LED production costs. It has applied for or possessed more than 330 international and domestic patents, among which 147 invention patents have been authorized, which realizes patent protection for each layer of the core components of epitaxial chips. At present, the first sapphire LED technology route is the mainstream technology route adopted by the industry, and the second silicon carbide LED technology route is a noble route. The core invention patents of these two technical routes have been monopolized by Japan, the United States and other countries, respectively, forming a patent barrier for the development of China's LED industry. Silicon substrate LED technology has become the world's third blue LED technology route, which has made China's LED industry fundamentally avoid patent disputes with the first two technology routes. Silicon substrate LED technology leads the industry development In the past few years, the high-end market of LED products has basically relied on imports, especially the high-power LED chips required in the high-end lighting market, and there is basically no production in China. High-end LEDs such as automotive lighting, outdoor lighting, high-end indoor lighting, mobile flashlights, and TV backlights are monopolized by foreign manufacturers. In June 2012, Jingneng Optoelectronics announced the mass production of silicon substrate high-power LED chips. This not only marks the maturity of silicon substrate LED technology, but also marks the end of the history of foreign monopoly high-power LED chips. As the only manufacturer in the world to mass produce silicon substrate LED chips, Jingneng Optoelectronics continuously optimizes processes and improves product performance. The performance of silicon substrate high-power LED chips is comparable to that of international mainstream manufacturers and has become the largest in Greater China. High-power LED chips and high-power ceramic package LED manufacturers. The success of the industrialization of LED technology on the silicon substrate in Jiangxi has led international companies such as Osram, Toshiba and Samsung to invest heavily in the development of silicon substrate LED technology. On January 8, the silicon substrate LED technology completed by Professor Jiang Fengyi of Nanchang University won the first prize of the 2015 National Technology Invention Award. Silicon substrate LED technology has changed the global LED industry landscape. With the technological advantages and industrial base, Jiangxi will undoubtedly make the pace of Nanchang Optical Valley faster and more stable. The scale of the silicon substrate LED industry cluster has been showing since the beginning of 2012, Jingneng Optoelectronics has started the counter-attack trend. In the market background where most of the LED companies' profits are seriously declining, the gross profit of 30% is maintained, and the sales revenue is nearly three consecutive years. 100% growth. In 2012, it began to be fully sold. In 2013, it earned US$33 million and its revenue in 2014 was US$60.99 million. At present, based on the silicon substrate LED technology, with the crystal energy photoelectric as the core, through the vertical integration of the industrial chain, the middle and lower reaches, the silicon substrate LED industry chain with 12 enterprises has been formed in the country, and the cluster size and radiation have begun to take shape. The driving effect is obvious. In 2013, the output value of the silicon substrate LED industry chain exceeded 1 billion yuan. In 2014, the whole industry chain realized an output value of 2 billion yuan. In 2015, it is expected to reach 5 billion yuan. In the next three years, the output value of 10 billion yuan will be formed. An industry with core technologies can sustain healthy development. If more companies join the silicon substrate LED industry chain, they can form a complete core industry-competitive lighting industry cluster from high-end equipment, raw materials, epitaxial chip manufacturing, packaged device modules, and lighting applications. It can achieve expansionary development from the inside and the outside. Wang Qiong, manager of Jingneng Optoelectronics Strategic Business Department, told the Jiangxi Network reporter that the silicon-based LED lighting industry cluster based on this technology will become a powerful force for China's LED industry to deal with patent litigation in the future. Jiangxi's pace of building Nanchang Optical Valley is faster. Jiangxi's independent innovation and research and development of silicon substrate LED technology won the first prize of the National Technology Invention Award. Jiangxi Province has drawn a roadmap for LED industry development: By 2020, the province's LED The main income of the industry should exceed 100 billion yuan, and Jiangxi will be built into a research and development, manufacturing and application base of LED industry chain with international core competitiveness, and Nanchang will become the national LED light valley. LED industry is a strategic emerging industry with comparative advantages in Jiangxi Province. Nanchang is one of the earliest regions engaged in LED R&D and production in China. It is also the national semiconductor lighting engineering industrialization base and plays an important role in the domestic LED industry. The silicon substrate LED technology independently developed by Nanchang University has laid a solid foundation for Jiangxi Province to build Nanchang Optical Valley and build Jiangxi LED industrial base. Since 2015, Jiangxi Provincial Party Secretary Qiangwei has held LED seminars three times, emphasizing that the conditions of silicon substrate LED technology and industry explosion have matured, and we must concentrate our efforts and resources to support the development of silicon substrate LED technology, with silicon substrate LED technology. For the core competitiveness, we will make every effort to build Nanchang Optical Valley. Looking forward to the 13th Five-Year Plan, the era of large-scale development of the silicon substrate LED industry has arrived, and the pace of creating Nanchang Optical Valley in Jiangxi is faster.
