In 1989, Mao Junfa graduated from the Chinese Academy of Sciences and entered the Shanghai Jiaotong University to pursue a doctoral degree. He studied under the tutor Li Zhengfan and studied the signal integrity of high-speed integrated circuits. Now he has been specializing in this field for nearly 30 years. Mao Junfa and the fate of integrated circuits meet. Together, Mao Junfa said, 'It is like a working partner to me. After dealing with it for so many years, there is always a sense of intimacy. I will continue to interact with it in this life.'
In the initial contact with the 'old partner', Mao Junfa and his men were keenly aware that there was a big gap between his research and the international leading scientific research level, which led to the idea of 'going out to see'. In 1994, he embarked on a trip. The Chinese University of Hong Kong is a 'question for a post-doctoral research'.
In the Chinese year of Hong Kong, he felt the huge contrast between the research environment and the living environment. He said, 'In that environment, I can understand the mentality that some young people will not come back when they go out.' Bearing in mind his own heart, even after going to the University of California, Berkeley for postdoctoral research, he always reminds himself that 'the school is calling me at all times.' After one year of work, Mao Junfa feels that 'Liangyuan is good, not a long-lasting love. Home also, and with the initial commitment to the mentor, he returned to Shanghai Jiaotong University to continue research.
In the 'President of the Shanghai Jiaotong University News Network', the president said, Mao Junfa said, 'The world is most afraid of serious words, one point of cultivation and one point of harvest; success is spelled out, talent is pulled out. 'He Recall that in the year of returning to China, the domestic living conditions and research environment were not very good. At that time, there was no laboratory, and only a 10 square meter corridor in the old teaching building could be used as an experimental place with the tutor. The summer is hot and humid, and there is no air conditioning. Sometimes it can't stand the heat, so I have to be shirtless when I am no one.
'Doing research will definitely encounter difficulties, but you can't back down.' Mao Junfa said frankly that as a researcher, working overtime at night is a common practice. Every time after work, dragging his tired body home, Mao Junfa feels extraordinarily, academic research is Hard and boring work, but it is difficult to make a difference without the spirit of loneliness and strong perseverance.
It was in such a hard sweat that the Mao Junfa team became the only team in Shanghai Jiaotong University to win the second prize of the National Natural Science Award, the second prize of the National Science and Technology Invention Award and the second prize of the National Science and Technology Progress Award. In November last year, he was elected to the Chinese Academy of Sciences. His research results have been widely quoted in the academic world, solving the bottleneck problem of incomplete information transmission in the rapid development of integrated circuits for the industry.
Life and death on the size of the fingernail
What is an integrated circuit? Mao Junfa described to reporters that, in simple terms, integrated circuits are due to the huge amount of data and information being processed. The number of components on the circuit is increasing, and there are hundreds of millions of transistors on a circuit. It is necessary to use a certain process to integrate different components into a chip smaller than the area of the human fingernail. This chip is an integrated circuit, which is a small, lightweight, large-scale, high-density circuit.
Some time ago, the 'Zhongxing Chip' incident highlighted the weakness of China's core chip, which sounded the alarm for the domestic 'chip +' industry, and the localization replaced the arrow on the string. Mao Junfa said, 'We used to call the wolf, now the wolf is really Come, the country has now spent a lot of effort to pay attention to this piece, we should sink our hearts and solve the difficulties of the chip in a solid way. The data shows that in the field of integrated circuits, Shanghai has become the domestic industry's most concentrated, the most industrial chain. One of the areas with complete, comprehensive technical level.
In fact, some domestic chips have reached the industry standard in terms of performance indicators, but because of the maturity of imported chips, more stable performance and lower prices, domestic chips are not favored. This is a vicious circle for chips. Mao Junfa said, 'Users find defects in the process of use, feedback to scientists and design companies to improve the product, in order to promote a benign development of a product, a complex thing can not be perfect in one step.
The ZTE incident reflects the imminent replacement of integrated circuits. At present, it is widely believed that the IC industry has high investment, long-term research and development, and slow results. Some capitals are reluctant to get involved, so everyone buys imported chips. It is understood that China is the world's largest integrated circuit consumer market. However, the supply rate of domestic chips is less than 10%. Among them, the dependence of enterprises on imported chips is self-evident. One side is the huge blue ocean market, and the other is the giant's eye-catching. It is both an opportunity and a challenge for the domestic integrated circuit industry. .
Mao Junfa believes that the future development trend of chips will be suspended, from the past 18 months to the current two or three years, but the chip will be smaller and faster.
Consolidating Hunan researchers to help Hunan develop
Mao Junfa said, 'After coming to Shanghai, my dreams were mainly concentrated in my hometown of Hunan before the age of forty, the scenery of my hometown, the hometown, the people of my hometown, all in my dreams. "Hometown is not only a soul for Mao Junfa. The dream of relying on the soul depends on him, and he is pinned on the spirit of thinking.
Since last year, the Hunan Provincial Party Committee and the provincial government have proposed the strategic thinking of “Innovation Leading the Open Rise” and the Furong Talent Plan. The government has realized that talent is the first resource for economic and social development, and the fundamental driving force for deep implementation of innovation to lead the strategy of open rise. Hunan has a lot of talents. Since ancient times, there have been 'only Chu and material, Yusi is Sheng'. 'According to my understanding, not only me, many Hunanese researchers in other places, the hometown complex is still very heavy, especially in Hunan. The people's feelings about their hometown are more affectionate. 'Mao Junfa said that how to use Hunan's scientific research personnel working in the field to do practical things for Hunan's science and education undertakings and high-tech industries is a topic worthy of discussion by leaders at all levels in Hunan.
