Beijing, outside the 21 pilot cities of the “Ten Cities and Ten Thousand Cities†project. However, Beijing's advantages are also obvious. It has strong advantages in epitaxial wafers and chips, and it cannot be compared anywhere else in the country. Beijing has the largest number of scientific research institutions, such as the Institute of Semiconductors and Microelectronics of the Chinese Academy of Sciences, Tsinghua University, and Beijing University of Technology. A few months ago, the Zhongguancun Semiconductor Lighting Industry Technology Alliance was announced, marking the strong involvement of Beijing in the LED industry. Beijing New Material Development Center is the secretary unit of the alliance. Recently, the author visited Wan Rong, the person in charge of the center, and Shen Guangdi, the head of Beijing Optoelectronics Technology Laboratory of Beijing University of Technology. Interview guest Wan Rong Secretary General of Zhongguancun Semiconductor Lighting Industry Technology Alliance Secretariat, Director of Beijing New Materials Development Center Shen Guangdi China's famous semiconductor and optoelectronics experts, Beijing Institute of Technology Beijing Photonics Technology Laboratory Under the circumstance of the “Ten Cities and Ten Thousand Citiesâ€, we expect Beijing to fully utilize its own advantages and form its own high-end voice in the construction of the influence of Beijing LED industry. Author: The outside world agrees that the establishment of the Zhongguancun LED Industry Alliance marks the strong involvement of Beijing in the LED product market. As the person in charge of the alliance, how do you view this kind of judgment? Wan Rong: Indeed, the development of the semiconductor lighting industry in 2003 and 2004 was obviously technology-oriented. After the Olympic Games, the development of the semiconductor lighting industry was market-oriented due to the demonstration of the Olympic Games. Shen Guangdi: I believe that the establishment of Zhongguancun LED semiconductor lighting industry technology alliance shows that Beijing attaches great importance to the LED industry and provides another platform for developing industries and strengthening exchanges between industries. This is a good opportunity to grasp This is a good time to develop the LED industry in Beijing. Author: What kind of consideration is Zhongguancun's establishment of the alliance at this time, or in what context? Is it late to enter the market this time? Wan Rong: Since Beijing's dominant units were mainly concentrated in the past few years, Beijing's support policy is mainly for science and technology projects to support key technology research and development. In recent years, with the rise and development of downstream enterprises, opportunities for industry-university-research cooperation to promote industry development have arrived. It should be said that it is not too early to establish this alliance in Zhongguancun, but it is certainly not too late. The purpose of establishing the Zhongguancun LED Industry Alliance is to promote the development of the LED industry: by setting up an LED industry alliance combining production, education and research, condensing upstream and downstream resources of the industry chain, promoting the development of LED technology and product standards, forming LED core technology and promoting high-end LED applications. To achieve industrialization, we have made a difference in the development of the domestic LED industry. Author: China's development in the LED semiconductor lighting industry can be described as obvious to all. How do you evaluate the current status of China's LED industry in recent years and its position in the international market? What is the development of Zhongguancun? Wanrong: In recent years, China's LED industry has maintained rapid growth. In 2008, the output value of domestic LED industry application products has exceeded 45 billion yuan. Relevant departments of the state have accelerated the development of the LED industry and the application of lighting energy-saving technologies through policy guidance and application demonstration projects such as “Ten Cities and Ten Thousand Citiesâ€. The LED industry is an emerging industry that will bring an emerging market. The LED industry development in Beijing has unique advantages and presents a dumbbell-shaped development structure. It has a good foundation in upstream R&D and downstream high-end applications, covering industrial chains such as equipment, epitaxial materials, chips, standards and high-end applications.  Shen Guangdi: The characteristics of LED are high upstream technology, low labor, low technical content in the middle and lower reaches, and labor intensive. Therefore, the middle and lower reaches of the Yangtze River Delta, the Pearl River Delta and the Delta are currently having a strong geographical advantage. Beijing The region also needs to develop the LED industry, especially the upstream epitaxy and chip industry, and give full play to the strength of scientific research in Beijing, so that more scientific research results can be transformed into products and productivity. Author: At present, how is the gold content of LED lighting technology in China? Overall, how far is the distance between laboratory level and industrialization? Based on the global LED lighting industry background, how is China's technology research and development and application status? Shen Guangdi: China's LED lighting has a huge application market. However, due to the fact that the chip itself has low luminous efficiency and high heat generation, the application field of LED lighting is limited. At present, it is mainly to improve the luminous efficiency of LED. Improve and improve from materials and processes. At present, the red LED technology of our Beijing Institute of Optoelectronic Technology Laboratory of Beijing University of Technology has fully capable of large-scale production, and is organizing the transfer of corresponding manpower and material resources to large-scale industrialization. In addition, the laboratory is in blue-green light. White LEDs have certain technical reserves and are accelerating research and development, gradually improving and industrializing. China's LED lighting has great development prospects and is a major event for the benefit of the country and the people. At present, the main force of LED technology research and development in China is concentrated in Beijing. The phenomenon of insufficient funds and imperfect equipment is widespread, which leads to great restrictions on the research and development of high-end products. Moreover, the outflow of high-tech R&D personnel is serious. The research and development work of the research unit is not closely integrated with the application. Many research units are only responsible for the research and development of technology, and there is no condition to complete the research of product application; while the company's R&D is directly linked to the application, The company's research and development foundation and research and development strength is not strong, resulting in low level of research and development. From the perspective of the overall development situation, semiconductor LED lighting is a revolution in lighting. With the continuous development of LED technology, its application fields will gradually expand. At present, the application of LED lighting is mainly concentrated in special lighting fields, such as: indicator lights, traffic lights, car lights, large screen displays, etc. In 2009, the development of backlights and high-power street lights, which are widely used in applications, Television and computer displays have become mainstream. As the technology matures, LEDs will surely enter every household, replacing all general lighting. Wanrong: The technology group includes transportation products such as display screens, street lamps and signal lights, landscape lighting and engineering (garden lamps and lanterns), and LED backlights and car lights that are still developing. China is not perfect in the LED lighting system. For example, there is no standard, and LED products in some high-power lighting fields have yet to be developed. Shen Guangdi: From the current development situation, China's LED products are mainly concentrated in the midstream packaging and downstream applications of the semiconductor industry chain. The upstream extension and chip technology are mainly in the United States, Japan and Taiwan, including Taiwan. The chip production in the region ranks first in the world. There are few domestic chip manufacturers and the scale is small. The technology is at the middle and low level. However, there are many packaging and application manufacturers in China, with low technical content and labor intensive. Most of these manufacturers rely on imported chip processing, and the products meet the needs of domestic and foreign markets. Therefore, in order to develop faster in China's LED industry, it is necessary to accelerate research and development in the upstream epitaxial wafers and chips, master the core and key technologies, and thus drive the development of the middle and downstream industries. Author: As a representative of emerging industries, why are LED-related products not included in the scope of government procurement? Wan Rong: This is actually not true. LED related products have been included in the scope of government procurement, according to our grasp of the situation; 1) Shenan Group's LED street lights have been included in the government's first purchase of independent innovation products catalog; 2) Tiananmen National Day 60th anniversary celebration in the form of government procurement The use of LED independent innovation products; 3) All the LED projects such as the Olympic Water Cube and Linglong Tower are directly supported by the Ministry of Science and Technology. Author: Relevant people alleged that if the LED industry does not absorb the lessons of China's new energy field, such as the photovoltaic industry, it will be difficult to get out of its own rhythm. What do you think? Wan Rong: I don't think so. The situation in other cities is not very well understood. Beijing mainly supports products with high-end industries with independent innovation, and industrial development is sustainable. Shen Guangdi: LED is a sunrise industry, and it is also an energy-saving and environmentally-friendly industry. However, in order to develop its own green lighting industry, China must realize and improve the development of the entire industry chain, from upstream chips, midstream packaging and downstream. The application of the technology, while combining the national conditions of China's development and application, to develop China's own LED lighting industry. Author: When it comes to technological innovation in the LED industry, what is the current reality in China in the field of lighting? What is the actual way out for China's LED lighting industry under the concept of original innovation, secondary innovation, and integrated innovation? Shen Guangdi: The technological innovation of the LED industry has been evident in the packaging and application fields in the middle and lower reaches, but the key technologies in the upstream have yet to be developed. At present, the main technologies are blocked by foreign patents, which brings great obstacles to the research of technology. Therefore, we only have to strengthen the power of R&D, and concentrate on the development of LED chips to better promote and develop China's LED industry. The author: "Ten Cities and Ten Thousand Miles" has been fully launched, how will the Zhongguancun LED Industry Alliance meet such an opportunity period? What role will the Zhongguancun Alliance play in building China's LED independent innovation lighting system? Wan Rong: First, relying on the alliance, actively seeking government procurement, supporting demonstration projects, such as the demonstration project of Starlight and several activities of the 60th anniversary of the National Day; second, relying on the alliance, making recommendations to the government to support the government's science and technology projects LED R&D and industrial development; third, promote the development of standard work; Fourth, the LED Industry Alliance will provide services and support for the “Ten Cities and Ten Thousands†project to cooperate with the “Ten Cities and Ten Thousand Citiesâ€. Smooth progress, in order to promote the development of Beijing LED energy-saving lighting industry. Shen Guangdi: China's LED lighting has huge market space. How to grasp this application market is the key to perfecting the entire LED industry chain, with independent intellectual property rights, and getting rid of the current situation of epitaxial wafers and chip-dependent imports. Currently, in the middle and low-end China has a certain production capacity on the chip, but high-end chips can only rely on imports because there is no technology and intellectual property rights, and 70% of the profits of the industrial chain are concentrated in the upstream, which leads to the development of the LED industry in China is not comprehensive. Therefore, the key is to develop upstream epitaxial wafers and chips, with independent intellectual property rights, thereby promoting and promoting the development of the middle and lower reaches, forming a semiconductor LED lighting industry in line with China's development status. Author: As far as the entire LED industry is concerned, what is the main focus of the Beijing Institute of Optoelectronic Technology Laboratory of Beijing University of Technology? What core technologies or product forms have been formed? Compared with domestic LED research institutions, where is the uniqueness of your laboratory? Shen Guangdi: Beijing Institute of Optoelectronic Technology Beijing University of Technology is mainly engaged in the research of LED epitaxial wafers and chips, including red light, blue green light and white light. It has applied for nearly 100 invention patents at home and abroad. At present, the red LED technology has reached the level of industrialization, fully possesses independent intellectual property rights, and its product performance has been judged by experts and comparative test analysis, and it is at the leading domestic level and international advanced level. The research on blue-green light and white light has proposed a unique physical structure. At present, the experimental verification work has been completed, and more experiments are being carried out to improve and optimize the structure and process of the device. Beijing University of Technology Beijing Optical and Electronic Technology Laboratory is affiliated to Beijing University of Technology and Beijing Municipal Science and Technology Commission. It was established in 1993 and is the first batch of Beijing High-Tech Laboratory. It is the key experiment of the Ministry of Education jointly established by the Ministry of Education and Beijing Municipality. Room is a national research entity engaged in the research of optoelectronic device technology earlier in China. Existing fixed assets of 50 million yuan, with international advanced material growth, chip preparation and testing and analysis equipment, such as MOCVD system, coating machine, cleavage machine, lithography machine, X-ray double crystal diffractometer, PL light fluorescence scanning system And the Hall test system, etc., has a clean laboratory of 600 square meters. Physical work on high-efficiency large-cavity high-power semiconductor laser devices, high-efficiency high-brightness light-emitting devices, new large-current high-current far-infrared detectors, SiGe/Si heterojunction devices, and ultra-high-speed SiGe/Si integrated circuit technologies The mechanism, the new device structure and the process preparation method all put forward innovative ideas, and obtained the results of the international advanced level with excellent performance. The room now has design specifications, research protocols, key technologies, technical routes, process preparation and testing techniques. Author: Zhongguancun LED Industry Alliance's recent work plan said: "In the next three years, the alliance will be committed to cultivating 6 to 8 leading enterprises in the industry, promoting the formation of high-end industrial clusters, achieving an industrial scale of 5 billion yuan, and promoting the construction of 3 to 5 signs. Sexual demonstration application engineering" Where is the previous foothold, what representative enterprises? Wanrong: The Alliance encourages and cultivates leading enterprises, and existing LED display and lighting companies such as Liard, Century Chengtong, Liangye Lighting, Shenan Group, etc. And there are two big leading companies that have already begun to see, one is Tongfang shares, and the other is Taishi Xinguang. (Tongfang Optoelectronics and Taishi Xinguang are building LED epitaxial materials and chip manufacturing projects to form an upstream high-end industry in Beijing. It is expected that 200,000 epitaxial wafers will be formed within 3 years, and the chip will have a production capacity of more than 3 billion pieces, with an annual output value of 3 billion yuan. Above.) At the same time, it has also begun to develop in industries such as LED driver chips. Author: China's LED industry alliance has been quietly exploring the actual solutions of the provinces and cities themselves, but they all call for the introduction of national standards in this field. In which areas do you think China's LED field will be regulated? Because this reflects the integrity of China's LED market. At the same time, what are the supporting conditions for the development of China's LED industry? Wan Rong: Beijing will vigorously promote the standards, and the Ministry of Science and Technology supports the progress of LED testing standards. The Alliance will actively promote support for standards development and strive to make breakthroughs in some specific product standards. LED industry development needs to meet the following conditions: the government's guidance, subsidies like one yuan energy-saving lamps for LED street lights or LED lighting and lighting products. Author: Guangdong Province LED standard as China's first provincial and municipal local industry standards, what do you think this will play a leading role for China's LED industry development? Wan Rong: The standard setting of Guangdong Province has certain guiding significance. However, to become a national standard, it still needs the recognition of the country and localities. All localities are aware of the importance of standards. Beijing has unique advantages in the formulation of standards.  Beijing is different from other regions in that it is not the same as the industrial group. Beijing is not suitable for traditional ordinary manufacturing. For example, LED packaging covers a large area. It is very difficult to do in Beijing. Beijing land prices and personnel costs are high. The package is basically not and rarely in Beijing. So basically not suitable. The Pearl River Delta and the Yangtze River Delta are the most packaged companies. The package is very simple. I bought the chip from abroad or Taiwan, or the low-end chip made in China. Once I get a package, it becomes a product, so I can get it in the mid-end market. It seems that they do a lot of LEDs and there are a lot of companies, but they don't have the high-end of research and development and high-end products, and the high-end of applications. They are not mastered. These two high-ends are precisely the most advantageous in Beijing. Wan Rong: Work will be carried out in six aspects. 1. In the field of LED epitaxial materials and chip manufacturing, accelerate the formation of industrialization capabilities through industry-university-research cooperation (Chinese Academy of Sciences, Institute of Physics, Chinese Academy of Sciences, Tsinghua University of Integrated Optoelectronics, Peking University, Beijing University of Technology) R&D institutions such as the University Optoelectronics Technology Laboratory are in the leading position in the field of epitaxial growth and chip manufacturing technology for high-brightness LEDs, and actively develop 130ml/w white light technology based on the national semiconductor lighting research and development platform built by the Institute of Semiconductors of the Chinese Academy of Sciences.) Second, in the localization of major equipment, through the support of the state and Beijing, further research and development of MOCVD production equipment. (The Institute of Semiconductors of the Chinese Academy of Sciences has developed a 7-piece MOCVD major equipment prototype, and has the technical basis for the development of 20-piece and above equipment. The next step will be to support the state funding, while actively attracting industrial capital investment and promoting the localization of major equipment.) Third, in the LED lighting standard creation, through standard cooperation, improve Beijing's leading ability to the development of the LED industry. (Beijing Electric Light Source Research Institute (National Electric Light Source Quality Supervision and Inspection Center), China Academy of Building Sciences Institute of Building Physics (National Construction Engineering Quality Supervision and Inspection Center Lighting Quality Inspection Department) and other Beijing testing agencies have compiled more than ten LED lighting technologies and products Relevant standards, the alliance will jointly test institutions, industry organizations and key users, in the chip manufacturing, testing, packaging devices, high-end LED products applications to promote the establishment of a number of national and industry standards. Fourth, in the field of LED backlight application, promote the research and industrialization of enterprises with strong strength. (LED backlight is a new application form of LED with great industrial potential. It has been paid attention to by many multinational companies and invested in R&D. BOE and Tongfang have already established a certain foundation in the research and development of backlight products. The alliance will promote Beijing. Start the research and development and industrialization of the application products, and accelerate the formation of output value and new industrial growth points. 5. In the high-end field of large-screen full-color reality and landscape lighting applications, actively support enterprises to undertake a number of major teacher projects and expand the market influence of Beijing's dominant enterprises. (More than 20 LED display manufacturers represented by Eliad, Century Chengtong and other enterprises have formed strong R&D strength and certain industrial scale through the construction of major projects such as the Olympic Games. Liangye Lighting Company is in landscape lighting The design has a high reputation. The next step will be to help the company to connect with major projects and demonstration projects inside and outside Beijing to enhance the brand awareness of Beijing enterprises and expand market capacity and share. Sixth, in the new application fields such as intelligent transportation, solar LED lights, high-brightness lighting, etc., strive for government procurement and other methods to promote the application of new technologies and new products. (Beijing has successively completed the traffic LED reality system in the Fourth Ring Road, the 40,000 solar street lamps in the suburbs, the capital international airport and the financial street high pole light project. Sitong Intelligent, Shenan Group and other enterprises have certain advantages in the above fields. The Alliance will recommend municipal enterprises to independently innovate LED application products to municipal, transportation, construction and other competent departments, and help enterprises improve product performance and quality through government procurement, laying the foundation for replacing traditional lighting.
