Reflections on the development of China's semiconductor lighting industry in 2008

The Fifteenth National compound semiconductor materials, microwave devices and Optoelectronic Devices Conference 3 held in Guangzhou on December 1st, the meeting hosted by Chinese Institute of electronics, semiconductor and integrated circuit branch, electronic materials branch, is the highest level of domestic compound semiconductor, microwave devices and optoelectronic devices conference.

With the development and application of semiconductor lighting, the compound semiconductors represented by GaN have been paid great attention to by the research and industrial organizations, such as GaN. To this end, the General Assembly invited academician Wang Zhanguo introduced GaN based materials and devices in the application of laser display, academician Zheng Youdou on the group III nitride semiconductor development in the face of scientific and technical issues related to the report. In semiconductor lighting, Congress is the director, invited the National Semiconductor Lighting Project Office of the national semiconductor lighting engineering research and Industry Alliance secretary general introduced the status quo and development trend of semiconductor lighting China, director of Institute of Chinese Academy of Sciences, national semiconductor lighting semiconductor R & D and Industry Alliance chairman Ming Engineering R & D director Li Jinmin introduced the latest progress of semiconductor lighting technology the.

Wu Ling, director of the semiconductor lighting in terms of reducing energy consumption, energy saving and environmental protection, the transformation of traditional industries and emerging industries such as the function and industrial base, and China pointed out that in twenty-first Century the rapid development of the city process, the main investment 4 trillion pull domestic demand plan will provide great opportunities for the development of China's semiconductor lighting based on facilities.

Director Wu Ling also proposed the concept of semiconductor lighting industry "tops, site": "heaven" refers to the technology is not only used in lighting technology, such as GaN III nitride semiconductor technology related to or involving strategic high-tech Information Photonics, optoelectronics, microwave energy power devices and power electronic devices; "site" refers to the scale of semiconductor lighting has been applied in many fields, for people's work and life bring real convenience, has become a part of people's livelihood. She believes that this makes the semiconductor lighting technology and industry to form a kind of edge flowering, the results of the model, so that the semiconductor lighting industry has a long period of sustained growth in the technology and industrial base.

Semiconductor lighting technology and industry there is still a lot of space, academician Zheng Youliao pointed out that the group III nitride semiconductor is a development of materials, the development of at least 20 years or more. MOCVD GaN is the key material growth and semiconductor lighting industry, the current equipment is still far from mature, the industry urgently needed new alternative MOCVD equipment; the development of new substrate constantly breakthrough technology route of epitaxial material growth have more choice is the focus of technology and industry. Will this be an opportunity or a challenge? How do we respond? Director Wu Ling believes that this is a semiconductor lighting research and development and industry needs to consider the issue of certification.

According to the conference report, at present China's semiconductor lighting industry has formed a larger scale, the total number of enterprises reached more than 3 thousand, the first half of 2008, affected by the financial turmoil, the development of semiconductor lighting industry is also showing a new trend.

Epitaxial chip enterprises in China into 50, MOCVD equipment more than 100 units, in 2008 the chip capacity is expected to grow by more than 30%. But overall, small scale enterprises, especially from the beginning of the year, chip prices fell nearly half, resulting in insufficient profitability, chip companies began to enter the winter; China packaging enterprises, nearly 1000, with the scale of the enterprise has more than 100. Packaging enterprises in early 2008, the rapid expansion of production capacity, equipment investment is large, the size of the package is still a high growth enterprise sales. Affected by the financial crisis, the second half of small scale, in the low-end market, export processing enterprises closed down more than 70, the pace of packaging enterprise difficult; China downstream applications more than 2000 enterprises, the application of new products and emerging markets, special lighting products have been mature market from the display to change from lighting, special lighting to general lighting, general lighting industry leading big opportunity. In the application of product types and scale, China is at the forefront of the world, has become the world's LED full-color display, solar LED, landscape lighting and other products of the largest production and export country. But the total body, the enterprise is small and the lack of brand, a larger traditional lighting companies wait and see, the development of semiconductor lighting industry needs to upgrade.

In view of the impact of the financial crisis on the development of the industry, Wu Ling, director of the analysis and outlook, she believes that the development of semiconductor lighting industry will slow down, is expected to grow in 2009 will be around 15%. From the beginning of the fourth quarter of 2009, the domestic semiconductor lighting industry will be significantly increased, by 2010 the growth rate of LED will reach more than 50%. In the long run, the development of the industry is optimistic and worth looking forward to.

In addition, in the face of the global economic downturn crisis, GDP upgrade is essential for economic development. At present, the global lighting consumes 8.9% of the energy and the power of the, the contribution rate of GDP is 0.63%. According to the Research Report of United States Department of energy and Sandia National Laboratory, along with the development of semiconductor lighting technology, lighting energy consumption and costs will be substantially reduced, so that the lighting demand increases, thereby increasing the contribution rate of GDP lighting, lighting is expected in 2050 the contribution rate of GDP will increase to 1.63%.

Opportunities and challenges coexist, the impact of the financial tsunami on the real economy is that we face severe challenges, and stimulating domestic demand, enhance industrial structure
