Beijing University for the development of China's LED lighting chip contribute

Recently, to bear the "power type high brightness light-emitting diode (LED) package" for the unit of the first node comprehensive performance appraisal, Peking University, Institute of semiconductors, Beijing science and Technology Co., Ltd. Ruiyuan joint scientific and technological projects, because the key technology breakthrough and won the first place. This breakthrough is in the national semiconductor lighting project, the national "863" project and the Peking University "985", "211" project under the support of. Along with the development of GaN based white LED research and industrialization, a lighting revolution at the beginning of this century has become the focus in the field of science and technology competition in the advanced countries of the world. High tech development and industrialization of our country science and technology department in May 2003 the relevant leaders made a special trip to the Peking University School of physics of white LED (light emitting diode) lighting source investigation, and check out the Peking University GaN based wide gap semiconductor research center to carry out the semiconductor optoelectronic materials and devices research situation. In June the State Ministry of science and technology officially launched the "national semiconductor lighting project", at the same time, the Ministry of science and Technology launched an emergency "fifteen" national key scientific research program, "semiconductor lighting industry technology development" project was launched. The country in the field of more than 40 research units and enterprises to tackle this project. Peking University, the Institute of semiconductors, the joint Beijing Ruiyuan "power type high brightness light-emitting diode package and industrialization of key technologies" research. 31 October calendar nearly a month of field inspection, dynamic process, standardized testing, packaging and appraisal, through the expert group assessment, comprehensive assessment of the first node in the national rankings bear the high power LED chip packaging and application unit, Peking University, semiconductor, and made the first Beijing ruiyuan. Peking University wide bandgap semiconductor research center also uses the laser stripping technology, developed China's first vertical structure, upper and lower electrode blue LED chip, LED to improve the light efficiency in the application of photonic crystals, also a breakthrough in the domestic and international leading position, for the further development of LED lighting chip to lay a solid foundation.
