Progress in key technologies for efficient semiconductor lighting materials


The official news of the Ministry of Science and Technology shows that semiconductor lighting has the characteristics of rapid technological development, wide application fields, strong industrial driving, and huge energy saving potential, and has established a dominant position in the transformation of the lighting industry. After years of development, the domestic semiconductor lighting industry has begun to take shape and has begun to accelerate its penetration into the general lighting field.

During the “Twelfth Five-Year Plan” period, the 863 Program focused on supporting the “Key Technology Development of Key Technologies for High-Efficiency Semiconductor Lighting (Four Phases)” project. Recently, the High-tech Department of the Ministry of Science and Technology organized experts in Beijing to check the project. In order to improve the reliability and controllable life of LED lighting systems, the project will study the reliability and controllable life technology of LED lighting systems, and study the practical mechanism of light, electricity, heat and machinery from materials and key components. Interaction, establish effective model and evaluation methods for LED key components and systems, improve the reliability of semiconductor lighting products; develop large-size (6-inch) silicon substrate epitaxial technology and phosphor direct-coated white light chip technology to simplify packaging process and lamps Heat dissipation and optical design, improve lighting quality and reduce lamp cost, it is of great significance to accelerate the entry of LED lighting products into the general lighting market and enhance the international competitiveness of China's semiconductor lighting industry.

During the “Thirteenth Five-Year Plan” period, in order to further promote the technological innovation and industrialization development of China's semiconductor lighting materials, the Ministry of Science and Technology deployed a special project of “strategic advanced electronic materials” to develop third-generation semiconductor materials and semiconductor lighting as key special projects. One of the key points to support. The special deployment will further lay a solid foundation for China to develop into a strong country in the production, consumption and export of semiconductor lighting products, supporting the industrial transformation of the global lighting industry and the sustainable development of energy conservation and emission reduction.
