'At present, China has mastered the key technologies of low-end optoelectronic devices, with production capacity, but the capacity is insufficient. In the research and development of high-end optoelectronic devices, some key technologies have made breakthrough progress. Prototype devices have been successfully tested through system functions, and some key technologies have been developed. It has reached the international advanced level. ' Zhu Ninghua introduced that only from the 12th Five-Year Plan of the '863' Plan, the State targets areas such as broadband communications, high-performance computers, backbone networks, optical switching, access networks, wireless communications and microwave lightwave convergence. Optoelectronic devices in the direction of the key deployment.
'A lot of these R&D projects are forward-looking. ZTE's all chips that are subject to this restriction have been deployed in the 12th and 13th national research plans.' Zhu Ninghua said that semiconductor lasers are called At the heart of the information network, it can be seen that the optoelectronic devices represented by lasers play an important role in communication system equipment. In optical transmission and switching equipment, optical devices account for 60% to 70 percent of the cost, therefore, in recent years in China, Has always attached great importance to the research and development of optoelectronic devices.
Zhu Ninghua analyzed that China currently has the basic conditions for the development of high-end chips for optoelectronics. Whether it involves technology accumulation or capital investment, as well as the cultivation and storage of high-end core talents, all have certain basic conditions. 'As long as the country selects information networks for the future, it is urgently needed. 1-2 key core optoelectronic chips, centralized resources, comprehensive layout from design, R&D, device preparation to packaging and testing, and through national guidance, local and corporate participation, build a complete optoelectronic chip processing technology platform, I believe high-end chip R&D The short board can be relieved within 5 years. '
According to reports, in order to achieve independent innovation and development, China implemented a major national science and technology project, "Very large scale integrated circuit manufacturing equipment and complete sets of processes," in 2008. After nine years of research, China successfully created an integrated circuit manufacturing innovation system in China. In the past, the most advanced mass production process for domestic integrated circuit manufacturing was 130 nanometers, and the R&D process was 90 nanometers. In the past nine years, the mainstream process level in China has been upgraded for five generations, and the three generations of 55, 40, and 28 nanometer process technologies have been successfully developed and mass-produced. 22, 14 nanometer pilot technology breakthroughs have been achieved, and more than 30 high-end equipment and targets such as 14nm etching machine, thin film deposition, and hundreds of material products such as polishing liquid have been successfully developed. The performance has reached the international advanced level. Packaging companies also from The low-end enters the high-end, and the three-dimensional high-density integrated technology has reached the international advanced level. This series of breakthroughs from scratch has filled the blank of the industry chain, and has enabled China's integrated circuit manufacturing technology system and industrial ecology to be established and improved.
The 13th Five-Year National Key Development Program on Broadband Communication and New Network Key Expert Group members, Professor Li Hongbin of Peking University, said that the achievements of China's communications industry have been evident in recent years. 'Starting from agricultural switchboards and edge equipment, and now full coverage of communications equipment products. From 2G, 3G to 4G, 5G, China's communications industry has developed rapidly, and it has already ranked among the top in the world in communication system technology.
Li Hongbin said that the development of anything requires a process. China's communications industry is also undergoing a process from low-end to high-end. 'In fact, many companies have invested a lot of R&D efforts in high-end R&D during these years. Companies have been making key chips for a decade or two, and they have also achieved innovative results. This is a market-driven result. It has also become the consensus of many entrepreneurs. Enterprises must achieve high quality development and gain more profits. , must invest more effort in high-end research and development. The enthusiasm of companies in investing in research and development of high-end chips can be described with eagerness and general trend.
Li Hongbin introduced that in recent years, China has stepped up its layout in the field of information and communications, organized major projects, and implemented various projects. Some companies rely on national investment alone for their own platforms that cannot be realized, and equipment has achieved initial success and will play a greater role in the future. 'As long as we adhere to the existing openness, competitive cooperation, and common development path, we must concentrate our government, R&D institutions, and the superior strength of the enterprise. We believe that it will not take too long to achieve the same order on the core of the industry chain. The achievements of the world. '
