Foreign media reported that the Chinese R&D team has broken through the limit of the chip. The thickness of the transistor is only three atoms, reaching 0.3 nanometers, which broke the previous concept that the chip industry believed that 1 nanometer was the limit of silicon-based chip technology. However, this technology is Owned by the United States.
The research and development team that made the technological breakthrough this time is the Massachusetts Institute of Technology, but the team is led by Chinese, and a large proportion of the technicians involved in the research and development are Chinese. This technology not only solves the problem of improving the performance of silicon-based chips , It also greatly reduces power consumption and prolongs the life of silicon-based chips.
The MIT research team developed an atomic-level transistor based on molybdenum disulfide (MoS2). Since the transistor is small enough, it also avoids the breakdown effect, which can effectively solve the problem that the power consumption cannot be controlled when the transistor shrinks to a certain extent. It is estimated that Chips developed with this transistor technology would consume only one-thousandth the power of current chips.
Chip foundry companies such as TSMC have developed advanced chip manufacturing processes by continuously shrinking transistors. However, with the development of chip manufacturing processes to 5 nanometers, the breakdown effect caused by too small transistors has become more and more serious. The development difficulty of the process continues the FinFET technology, but it leads to a relatively limited increase in chip performance, and the cost increases too fast. This is the reason why TSMC’s 3nm process was not approved by Apple last year. In desperation, TSMC can only continue to improve 3nm , It is expected that the improved 3nm process N3E will receive orders from Apple this year.
Samsung pioneered the introduction of GAA surround gate technology. Its 3nm process performance is better than TSMC, and its power consumption is also better. However, because Samsung is too aggressive, the yield rate of the 3nm process is too low. It has not announced who its 3nm process customers are, which makes people suspect that Samsung's 3nm process has not been recognized by any chip companies.
The 3nm process has already faced such difficulties. Whether the 2nm process claimed by TSMC and Samsung can be advanced as scheduled is doubtful. The transistor technology developed by MIT may once again open the direction of silicon-based chips, thus continuing the current silicon-based technology. Chip technology lifetime.
The Chinese team at MIT has achieved a breakthrough in chip technology, which proves the talent of the Chinese in chip technology research and development. It is estimated that there may be more than tens of thousands of Chinese people engaged in technology research and development in Silicon Valley, and they have made important contributions to the development of American technology. , highlighting the importance of the Chinese to the US technology industry.
In fact, it is not that the Chinese have made important contributions to the development of chip technology. When the dry lithography machine was transformed into the immersion lithography machine, it was developed by Lin Benjian, the technical director of TSMC, and then handed over this technology to ASML, thus ASML has become the world's largest lithography machine company from a lingering lithography machine company, and the Japanese lithography machine, which once occupied nearly 80% of the global lithography machine market, is rapidly declining.
The FinFET technology that led the development of the global chip manufacturing process from 20 nanometers to 5 nanometers was invented by the Chinese Professor Hu Zhengming, and then the development of this technology was promoted by several apprentices of Professor Hu Zhengming, such as Liang Mengsong and others. They helped TSMC to promote the development of advanced technology. Research and development, and finally defeated the US chip leader Intel, and established the status of chip manufacturing leader.
When these chip technologies gradually reached the bottleneck, the MIT R&D team that opened up the situation for chip technology was led by Chinese again. It will help the United States regain its status as a leader in chip technology.
The United States once again made a breakthrough in chip technology, which is undoubtedly a considerable blow to the Chinese chip industry. This means that the gap between China's chip technology research and development and the United States has once again widened. Foreign media therefore believe that Chinese chips are in a technological contest. It failed yet again, but it may be too early to tell.
Although Chinese chips are still catching up with the United States in terms of silicon-based chips, the Chinese chip industry is trying to overtake in new chip technology. China has prepared to build the world's first production line for photonic chips and quantum chips. If photonic chips and quantum chips are commercialized , then the existing silicon-based chip technology will be completely subverted, which means that Chinese chips still have a chance to catch up, but it is necessary to speed up the commercial process of these new chip technologies.
