In order to accelerate the advancement of semiconductor lighting technology and industrial development, and support the development of strategic emerging industries for semiconductor lighting, the Ministry of Science and Technology has thoroughly studied and demonstrated the "12th Five-Year Plan" for the development of semiconductor lighting technology on the basis of preliminary research. Hereinafter referred to as the "Special Plan" and extensively solicited opinions.
The "Special Plan" has been published in full. What is the background of the planning and development? What are the overall goals and principles for the development of China's semiconductor “Twelfth Five-Year Plan� In which semiconductor lighting technology and application areas will China focus on? What key breakthroughs are achieved? How to ensure that the special plans are implemented? To this end, the person in charge of the High-tech Department of the Ministry of Science and Technology accepted an interview with the reporter and answered questions on the relevant situation.
Reporter: What are the trends in international semiconductor lighting technology and industry development?
A: In recent years, semiconductor lighting technology has developed rapidly and is developing in the areas of high light efficiency, low cost, more reliable, diversified fields and wider application. Although the speed of semiconductor lighting technology innovation far exceeds expectations, there is still much room for innovation compared to theoretical light effects. The focus of semiconductor lighting technology is focused on GaN-based LED epitaxial materials and chips, high-efficiency high-brightness high-power LED devices, LED functional lighting products, OLED lighting, semiconductor lighting innovation applications, and MOCVD metal organic chemical vapor deposition equipment and other major equipment development. etc.
Semiconductor lighting is considered to be the most strategic emerging industry in the 21st century. In recent years, governments around the world have arranged special funds, set up special plans, and formulated strict incandescent lamp elimination plans to support domestic semiconductor lighting technology innovation and industrial development.
Reporter: What is the development demand and current level of semiconductor lighting in China?
A: With the pursuit of higher lighting quality, the rapid development of the semiconductor lighting application market, and the increasing pressure on energy saving and emission reduction in the urbanization process, it is urgent to develop key technologies for the industrialization of LED light sources and lighting products; At the same time, the development of the semiconductor lighting industry is also conducive to the transformation and upgrading of the national economy pillar industries such as new display, digital home appliances, automobiles and equipment. In addition, the semiconductor lighting industry's technology and labor-intensive features can create more jobs.
Driven by the continued support of the national science and technology plan R&D investment and market demand, China's semiconductor lighting technology innovation capability has been rapidly improved. The domestic power-type white LED device has a luminous efficiency of more than 120 lm/W, which is close to the international advanced level. The Si substrate power type LED device with core independent intellectual property rights has been industrialized, and the luminous efficiency exceeds 100lm/W; the indication, display and medium and large-size backlight industries have begun to take shape, and the functional lighting energy-saving effect has already appeared. Twenty-two national and industry standards have been developed and published.
Reporter: What are the gaps between China's semiconductor lighting industry and the international level? What is the significance of the implementation of the special plan?
A: The gap between China's semiconductor lighting industry and the international advanced level is mainly reflected in: the core equipment and some raw materials such as MOCVD still rely on imports; the epitaxial chip lacks core patents; the test methods and equipment support are insufficient; the research and layout of related patents and technical specifications lags behind Industrial Development.
In the critical period of seizing the commanding heights of the industry, the formulation of special plans for semiconductor lighting will help to further clarify the key directions of China's technological breakthroughs in the next five years, so as to concentrate resources on solving technical bottlenecks in industrial development and gradually narrow the gap between technological innovation and international level in the upstream of the industrial chain. Leap-forward development in downstream lighting applications through system integration innovation.
