Yangzhou, Jiangsu Province, China, through the combination of production, study and research, has shown a good momentum in the key technologies of the LED industry chain and its industrialization, introduction and training of professional talents.

First, the key support of Jiangsu Province, the key development of Yangzhou City, the promotion of the province and the city

Jiangsu Province implemented a strategy of differential dislocation competition along the Yangtze River to determine Yangzhou's focus on building a semiconductor lighting industry. In 2006, the Ministry of Science and Technology and the Jiangsu Provincial People's Government jointly signed the "Working Conference Protocol", Yangzhou National Semiconductor Lighting Engineering Industrialization Base as one of the provincial and ministerial consultations. At present, the city has formed a good atmosphere for the development of the semiconductor lighting industry.

In 2006, Yangzhou launched the infrastructure construction of a 2 square kilometer LED new light source industrial park. Yangzhou New Light Source Technology Development Co., Ltd. was established in the High-tech Zone, responsible for the construction of the new light source industrial park R&D center. In 2007, CLP 55 Research Institute, Guangxu Xing, Taiding and other LED related companies engaged in wafer production, packaging and brackets started construction in the new light source industrial park, with a total investment of 69.30 million US dollars.

Second, the industry chain is getting better and better, and key technology research and development shows a good momentum of development.

At present, there are more than 10 core enterprises engaged in semiconductor lighting production and development in Yangzhou. Among them: 3 substrate material manufacturers, 2 epitaxial wafer manufacturers, 1 wafer oxygen manufacturer, 2 stent and substrate manufacturers, 7 LED packaging manufacturers and many application enterprises.

Yangzhou High Energy New Materials Co., Ltd. has developed a new process of “arsenic-lead alloy hydrogen atmosphere? N Huafa” to produce high-purity arsenic in cooperation with the Institute of Semiconductors of the Chinese Academy of Sciences, Tsinghua University and Jiangsu University, compared with the traditional “chlorination distillation process”. It has the advantages of environmental protection, no pollution, industrialization, high product purity and low cost. The process has been patented.

Yangzhou Huaxia Optoelectronics Co., Ltd. develops and produces four-element InGaAlP red, yellow and yellow-green high-brightness LED chips and GaN blue and green high-brightness LED chips on the slab. At present, Huaxia Opto's AlGaInP quaternary wafer production has reached 500 KK / month, ranking first in the domestic market, and is one of the largest quaternary capacity manufacturers in mainland China.

Yangzhou has a large number of LED downstream packaging application manufacturers, invested a lot of resources in application research and development, and solved many practical problems. For example, 裼眯滦蜕(4) 冉峁 ?? solves the problem of heat dissipation of LEDs applied to street lamps; 袢 绻饣ゲ 绻饣ゲ 尴叽 尴叽 尴叽 尴叽 感 感 , , , , , 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能 太阳能Charging, to achieve the purpose of use on a sunny day.

Third, establish a platform for research and development, information exchange and communication, and promote cooperation between industry, universities and research institutes

According to the "Huaxia Semiconductor Lighting Research Center", research and development of high-power LED chip technology and LED packaging technology has gathered a group of professional technology research from LED research and development and production companies such as Taiwan New Crystal, Yuan Arsenic and Yuyuan. personnel. In January 2007, more than 20 semiconductor lighting related companies initiated the establishment of the "Yangzhou Semiconductor Lighting Industry Alliance" to promote the industry self-discipline of Yangzhou's semiconductor lighting industry and promote the rapid, healthy and sustainable development of the semiconductor lighting industry in Yangzhou.
