Set micro-grid launch micro-channel IC WeChat public number: 'Daily IC', real-time release of major news, every day IC, every day set of micro-network, micro-into a!
1. Ye Tianchun: China's IC industry chain cultivation and layout basically completed;
In recent years, the state has provided significant support to IC companies in terms of capital, policies, financing and human resources, and the IC industry in China has developed rapidly. According to the China Semiconductor Industry Depth Analysis Report released by Jibang Consulting, in 2017, China Semiconductor output will reach 517.6 billion yuan, an increase of 19.39%.
At a forum held in Kunshan on the 25th, Ye Tianchun, director of the Institute of Microelectronics at the Chinese Academy of Sciences, said: "China's integrated circuit industry has established a more complete technical system and the industrial chain has basically completed the cultivation and layout." However, China's dependence on the development of the integrated circuit industry Still high, domestic chip has a huge alternative space.
Ye Tianchun believes that Chinese enterprises should move from being 'substitutes' to 'innovators', filling the gaps in the layout of large-scale IDMs (Integrated Circuit System Integration Service Providers) and addressing the localization of several types of bulk integrated circuit products in a targeted manner. It should be promoted from a low-cost manufacturer to a technology solution provider and thus become a leader in the global semiconductor industry.
At the same time, Ye also urged that there should be vigilance on the rapidly growing semiconductor boom and to avoid overcapacity.China is a major global manufacturer of electronic products and a major consumer of integrated circuit products. China should focus on the application of the industry for business integration, Provide technical solutions.
2. The Carbon Family usher in new members: The predicted T-Carbon was born in the lab;
T-carbon is a new type of three-dimensional carbon structure predicted by theoretical calculations by Professor Gang Su Gang of the Chinese Academy of Sciences 6 years ago. The team's theoretical predictions make T-carbon another new three-dimensional structure of carbon that can compete with graphite and diamond, adding new members to the carbon family.
In 2011, Su Gang guided the doctoral candidates to sacrifice Lei, cooperating with Dr. Yan Qingbo, Professor Fei and Professor Zheng Qingrong. After a large number of comparative studies, it was proposed that if each carbon atom in the cubic diamond is composed of four carbon atoms Of tetrahedron structural units will form a new type of three-dimensional carbon crystal structure, they based on the first principles of density functional theory study and found that this structure in terms of geometry, energy and dynamics are extremely stable , And named this new carbon allotrope T-carbon.
Su Gang and others have shown that T-carbon has the same space group as diamond and is a semiconductor with a direct bandgap. T-carbon also has a distinctive feature, its density is very small, about 2/3 of graphite, T-carbon also has a high hardness. T-carbon is a fluffy carbon material, which has a large space available inside, if used for energy storage materials, its hydrogen storage capacity of not less than 7.7 Due to the above unique properties, T-carbon will have a wide range of potential applications in the fields of photocatalysis, adsorption, energy storage, aerospace materials and etc. Experts in the industry believe that this work opens up a new era of carbon structure research.
After careful calculations, Su et al found that T-carbon may be easily formed under negative pressure, and further studies have shown that T-carbon may be observed in cosmic interstellar dust or extrasolar planets.
Su Gang told the reporter of the "China Science News" that after completing the theoretical predictions, he has long devoted himself to the experimental synthesis of T-carbon. "Edison said that 99% of the experiments will fail, but there will surely be some gains. It is gratifying to note that a joint research team of Xi'an Jiaotong University and Nanyang Technological University in Singapore has finally become 1% of the lucky ones in 2017. By means of picosecond laser irradiation of multi-walled carbon nanotubes suspended in methanol solution, , They successfully achieved the transition from sp2 to sp3. The detailed structural study shows that the new carbon material formed is completely consistent with the theoretical predicted T-carbon, which proves the synthesis of T-carbon.
In addition, T-carbon experimental synthesis not only has attractive prospect in the application, but also has important scientific significance.In recent years, theorists have proposed a variety of carbon structural models, only T-carbon has been successfully synthesized experimentally, This is by no means a mere coincidence. "Astronomers have long observed that cosmic dust contains only 60% of the carbon in the solar system and has long been devoted to studying the mystery of the carbon crisis, and the density of T-carbon is exactly This seems to offer the inspiration that if the majority of the carbon in interstellar dust is in the form of T-carbon, is this the ultimate answer to an important scientific question such as the carbon crisis? "Su Gang told "China Science News" reporter.
Experiments on light absorption of T-carbon by the joint research team of Xi'an Jiaotong University and Nanyang Technological University in Singapore also showed that the position of the main light absorption peak is close to the position corresponding to the extinction curve drum in the interstellar dust. The final answer to this question also Astronomers are required to confirm further through astronomical observations that Su-Gang believes FAST, the largest mirror-diameter radio telescope in our country's newly built world, may play an important role in this regard.
3. The first batch of the first batch of provincial-level military and civilian integration industry development fund will be landing
November 25, 2017 Tianfu Financial Forum, the country's first provincial-level military and civilian integration industry development fund - Sichuan Tianfu Hongwei military integration industrial development equity investment fund leader disclosed that the fund-raising basically completed, more than 50 projects have been reserved A total demand of about 6.5 billion yuan of funds, the first three projects will be the recent official investment floor.
In January of this year, Sichuan Tianfu Hongwei Military and Industrial Integration Investment Fund was formally registered with a fund of 10 billion yuan.
'All three projects belong to Sichuan and have superior military and civilian industries combined with high-tech industries such as civil aerospace, civil aviation and compound semiconductor chip industries. "The director of the fund said that when the fund was established, it clearly invested in enterprises in Sichuan Province Or the proportion of the project is not less than 70% of the total fund size. The investment amount of a single project does not exceed 20% of the total fund size, and the investment is both "boosting" and "tapping potential."
'Yangzong' focuses on the integration of Sichuan's military and civilian areas into existing areas of advantage, covering areas where military and civilian industries are integrated with high-tech industries, technological transformation of enterprises participating in the armed forces' militaries, specialization and reorganization of military and industrial enterprises and institutions, industrial bases for military and civilian integration, and listed enterprises in the province. Science and Technology Office of the relevant person in charge of the introduction of Sichuan clear aviation, aerospace, compound semiconductor chips, information security and other civil and military integration major innovation projects are the focus of the fund investment direction .In the military and industrial enterprises specialized restructuring, the fund in April this year Has signed a strategic investment intention agreement with China Ordnance Equipment Research Institute, the first military research institute in the country that is trying to mix and reform pilot projects.
The "tapping potential" mainly provides support to small and medium-sized potential enterprises, and at present, the fund has already carried out moratorium on enterprises involved in military and civilian integration in the province, and 18 of 50 projects in reserve have started the pre-establishment investigation.
