On February 14, 2012, the 2011 National Science and Technology Awards Conference was held in Beijing. Dalian Meiming Epitaxial Film Technology Co., Ltd., Institute of Physics of Chinese Academy of Sciences, Tsinghua University and Dalian Lumei Chip Technology Co., Ltd. jointly developed the GaN base. The key technology and industrialization of blue-green LED has won the second prize of the 2011 National Science and Technology Progress Award. This is the first time that the semiconductor lighting field has won the National Science and Technology Progress Award. After more than 10 years of hard work and tireless pursuit, this scientific research achievement has finally achieved this remarkable achievement today.
The fabrication technology of GaN-based LED epitaxial wafers and chips is the most important development of strategic emerging industries of semiconductor lighting, with high technical content and difficulty. In order to break the monopoly of foreign patent technology and form a core intellectual property right with China's own independence, the strategic research and development cooperation between Meiming Epitaxial Film Co., Ltd. and Lumei Chip Co., Ltd. under the Dalian Luming Technology Group and the Institute of Physics of the Chinese Academy of Sciences and Tsinghua University . The research team led by Xiao Zhiguo combines the resources advantages of enterprises and colleges, adopts the joint research of technology and industry, continuously practices, tries repeatedly, and finally breaks through a series of technical difficulties through completely different technical means from foreign countries. It has overcome the technical bottlenecks that restrict the key technologies and industrialization of GaN-based blue-green LEDs, including: high dislocation density of epitaxial materials, low quantum efficiency in InGaN/GaN multiple quantum wells, low light extraction efficiency, and device reliability. Need to be improved. A number of core independent intellectual property rights have been achieved in key technologies and industrial implementation, and product performance has been synchronized with international advanced technologies. Quantum well structure design, Bragg reflectors, and capacitive structures are among the world's leading.
Based on years of research and development, the project has an early LED core patent in China and has accumulated solid industry experience. The world's recognized technical difficulties green light LED's comprehensive performance indicators have reached the same level of leadership, successfully realized the blue-green LED industrialization, has published more than 50 SCI papers, applied for more than 30 invention patents, authorized 14 projects, for the LED field nation The revitalization and development of the industry has laid an important foundation.
Through years of industrial accumulation, Dalian Meiming Epitaxial Film and Lumei Chip Company have built a complete set of production lines and modern workshops for the development, production and testing of LED chip epitaxial wafers in the industry. They have undertaken the National Semiconductor Lighting 863 Special Project and the Ministry of Industry and Information Technology Electronic Development Fund. More than 10 R&D and industrialization projects such as bidding; core patent technologies covering epitaxial growth from upstream epitaxial wafers to mid-stream chip manufacturing processes; and 6 national and provincial-level science and technology awards. It has made significant contributions to the rapid progress of China's semiconductor lighting field.
As a private enterprise, Luming Group won the National Science and Technology Award twice in five years, which has pushed Luming's technological innovation to a new height. Luming Group always adheres to the development concept of “Building a national brand and realizing China's creationâ€, adheres to technological innovation, and regards the development of independent intellectual property rights as its core competitiveness, striving to become a world-class semiconductor lighting enterprise.
