Accelerating the cultivation and development of strategic emerging industries based on major technological breakthroughs and major development needs is important for promoting the upgrading of industrial structure and the transformation of economic development mode, enhancing China's independent development capability and international competitiveness, and promoting sustainable economic and social development. significance.
As a strategic emerging industry, LED is in the ascendant. Under the pattern of Japan and the United States monopolizing the core technology of LED chips, Nanchang's enterprises have taken the tough battle and created the third technical route of global LED chips, and quickly realized industrialization. With the rapid change of technology means, under the fierce and fierce globalization of industrial competition, having the core technology and leading industry standards is the key to success. However, if new technologies are to become new industries, they will not be able to do so overnight.
The State Council executive meeting held recently proposed that we must adhere to the combination of market-based role and government guidance and promotion, combining scientific and technological innovation with industrialization, promoting the integration of industry, education and research with enterprises as the mainstay, and cultivating strategic emerging industries into the national economy. Pioneer industry and pillar industries. This is also the significance of our anatomy of the Nanchang LED industry.
Silicon-based lighting, China's creation, independent innovation, Guangming Wanli This is the inscription of the Minister of Science and Technology Wan Gang to a company in Nanchang, Jiangxi.
In the pattern of Japan and the United States monopolizing the core technology of LED chips, in 2008, Jingneng Optoelectronics Co., Ltd. located in the high-tech development zone of Nanchang City, Jiangxi Province, creatively developed a third technical route in the field of GaN-based semiconductor luminescent materials, becoming the only LED production enterprises with independent intellectual property rights of silicon substrate light-emitting diodes have attracted much attention.
LED light source is a low-voltage microelectronic product, and is also an emerging digital information product. Can the silicon-based luminescence created in China be the leading LED light source industry in the world?
More than 70% of the world's LED application products are manufactured and manufactured in China, but the core technology is controlled by Japan and the United States.
Since the 1990s, LEDs have stepped out of Japanese laboratories, rapidly industrializing the world, and ruining the traditional optoelectronic industry. In the short period of years when LED backlight technology entered the field of display, laptops and mobile phones produced by multinational companies have 100% LED display.
According to statistics, more than 70% of the world's LED application products are manufactured and manufactured in China. However, among the more than 1,000 LED manufacturers in China, there are only more than ten in the upstream of the industry.
The LED chip technology route upstream of the industrial chain is dominated by sapphire substrates and silicon carbide substrates, and core technologies and patents are controlled by Japan and the United States. Wang Min, vice president of Jingneng Optoelectronics Co., Ltd., said that the MOCVD equipment technology for producing LED chips is monopolized by AIXTRON and VEECO.
With the continuous expansion of the LED industry, developed countries such as Japan and the United States have set up technical barriers. In February 2010, the US Consumer Product Safety Commission and Innovage jointly implemented a voluntary recall of the Chinese-made Discovery Kids(TM) AnimatedMarine and Safari lamps. Previously, similar incidents have occurred many times. The lack of core technologies and patents has caused many Chinese companies to suffer frequent patent litigation.
The bigger threat is still behind. Since 2009, a large number of foreign-funded enterprises have begun to sprint in the Chinese LED market. Some insiders believe that when the application channel of LED technology has not been fully expanded, the domestic LED industry following the Japanese-American technology route has an over-investment in investment and production capacity.
Silicon-based lighting, a key step in breaking through the monopoly of foreign technology
In 2008, the team led by Prof. Jiang Fengyi from Nanchang University came out of the third technical route of global LED chips in the field of GaN-based semiconductor luminescent materials. Nowadays, in the LED components with only the hairline radius, Jingneng Optoelectronics has more than 130 international and domestic patent technologies.
The 863 project acceptance expert group evaluated the silicon substrate technology: this technology broke the current situation of Japanese monopoly sapphire substrate and Japan Cree monopoly silicon carbide substrate semiconductor lighting technology, forming sapphire, silicon carbide, silicon substrate The three-legged situation of semiconductor lighting technology solutions.
In just over a year, our LED chip sales accounted for about 10% of the domestic market, and more than 100 of the more than 1,000 downstream packaging companies in China have become our customers. Wang Min said. In June 2009, the chip products of Jingneng Optoelectronics Co., Ltd. were officially sold. This year, LED chip sales are expected to reach 14 billion.
Grasping the opportunity of the national ten-city Wanhao semiconductor lighting application engineering pilot project, Nanchang City takes crystal energy photoelectric as the leader, strengthens the research of silicon substrate technology and application, and focuses on supporting the industrialization of silicon substrate chips and focusing on the development of LED mid-stream and downstream application technologies. product. Only Nanchang High-tech Development Zone has gathered 15 semiconductor lighting companies with a certain scale, with an annual output of more than 10 billion sets of semiconductor lighting products, accounting for more than 25% of the national market.
At the beginning of this year, several well-known venture capital companies cooperated with relevant parties to invest heavily in the establishment of the Jinshajiang LED Industrial Park in Nanchang. Based on this new LED path with independent intellectual property rights, the LED industry of the upper, middle and lower reaches was integrated. Large industrial industrial park.
Leading the future, the LED industry is looking forward to Chinese standards
It is predicted that in 2010, the global lighting market will reach 100 billion US dollars. Due to its advantages of energy saving and emission reduction, LED light sources will gradually replace light sources such as incandescent lamps and eventually occupy this huge market.
At the recent Nanchang Green Lighting Industry Cooperation Promotion Conference held in China, Jiang Fengyi said that the domestic LED technology and the world-class core technology still have an efficiency gap of about 20% to 30%. If the high-end technology does not go, our profits are very low, we can only work for others.
From a strategic perspective, China's development of the LED industry must adhere to the silicon substrate technology route with independent intellectual property rights. In the strategic emerging industry of LED, this is also the only area in China that may come later. Liu Hua, director of the Research Office of Nanchang Development and Reform Commission, believes that the silicon-based luminescence technology created in China has the advantages of performance and cost. The biggest problem at present is promotion. The technical routes of Japan and the United States have been promoted for more than ten years, and a large number of multinational companies follow up and apply. Our biggest problem at present is the lack of supporting enterprises and the lack of uniform production standards and testing methods. The support and promotion of the government is urgent and crucial.
Emerging industries have their own national standards in order to truly grow and develop, and they can truly drive a new leap in the global LED industry. Wang Min said that the most urgent thing now is to make the new technology scale and maintain its advantages as soon as possible, and establish an industrial alliance of silicon substrate technology in China. We are willing to open all patented technologies for domestic and foreign enterprises to share.
In this sense, China’s dream of creating a illuminating world is just beginning.
