Jiangxi LED technology out of the third way

On the 20th, the 2010 China-Jiangxi (Nanchang) Green Lighting (Semiconductor Lighting) Industry Cooperation Promotion Conference was opened in Nanchang, including Prof. Song Xianjie, Deputy Director of the Institute of Electric Light Sources, Fudan University, Prof. Liu Xingren, Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, and others. Major industry experts will visit Nanchang and give academic reports.

It is understood that as one of the national semiconductor lighting engineering industrialization bases, Nanchang has occupied an important position in the field of LED research and industrialization in the country. For the production of LED chips, the selection of substrate materials is the primary consideration. The global industry mainly relies on Japanese sapphire substrate technology and the United States silicon carbide substrate technology, and now Jiangxi LED technology has gone beyond the third The road (ie silicon substrate technology) costs much less than Japan and the United States.

The reporter learned from the Jiangxi Provincial Industry and Information Technology Commission on the 19th that relying on local R&D advantages of LED core technologies, Jiangxi promoted the industrialization of “silicon bottom blue diode materials and devices” with independent intellectual property rights. Jiangxi Province has formulated the LED industry development goals, and strives to achieve a total output value of 20 billion yuan in the province's LED industry by 2012. It will turn Nanchang into a competitive LED industry base in China and even in the world.
