Chinese companies have already done it, the US think tank is helpless, and foreign countries**: admit it.
Stuck neck"The term has been mentioned repeatedly since 2019"Buzzwords"It means that the technology that may have an impact on our country due to the restrictive actions taken by Western countries is, to put it bluntly, the technology they have but we do not have. These technologies include operating systems, semiconductor chip manufacturing equipment, and industrial machinery.
Semiconductor chip manufacturing equipment is the most popular, because Western countries ordered TSMC and Samsung Electronics to cut off the supply of chips to Huawei, so the semiconductor chips were quickly solved"Stuck neck"The problem has been mentioned repeatedly, and among the semiconductor chip manufacturing equipment, the lithography machine, especially the entire chip manufacturing process in China, has attracted the most attention"The shortest"γIn addition, due to the extremely bloated ** chain involved in the lithography machine, it is also the most difficult to manufacture, especially the high-end EUV lithography machine.
Therefore, it is rumored that the manufacture of national chips can also be carried out as long as the national EUV lithography machine progresses.
It is undeniable that this statement has a certain basis, but it is not necessarily true, for example, at the end of August 2023, the analysis of Huawei's Kirin 9000s chip seems to have little to do with the progress of lithography technology, although so far, the outside world is not clear about the technology of the Kirin chip manufacturing ** chain, but it should be noted that this is a technical system that is completely independent of the European and American technology systems, otherwise Biden's actual has long been"Jumping feet"γ
And just when everyone was curious about the level of development of domestic integrated circuit technology, on January 12, the Center for Strategic and International Studies, a U.S. think tank, released an important piece of information, saying"Silicon photonics technology has become a new battlefield in the technology war between China and the United States, which may reshape the competitive landscape in the fields of semiconductors and artificial intelligence"γ
Unlike existing electronic chips, which use photons instead of electrons to transmit information, the combination of photonics and electronics has the potential to create large-scale computing systems with greater bandwidth and greater energy efficiency, overcoming the physical limitations of traditional electronic chips, the article said.
In fact, this is inevitable, for three years, the whole world has been signaling that the physical limit of silicon-based chips has been reached, and if you continue to improve the performance of the chip by reducing the process, the possibility will get worse and worse, because if the 1nm chip is smaller in the future, quantum tunneling will occur, destroying the basic computing power of the chip.
China"14th Five-Year Plan"Planning Outline and"Vision 2035"It is also explicitly mentioned that photonic technology is one of the ways to circumvent the control of Western technology.
At present, China's Zhongke Xintong Microelectronics Co., Ltd. is preparing to build a photonic chip production line, which shows that our Chinese companies have been taking action, and the effect must be good, otherwise the American think tank can only speak.
Choosing photonic technology to break the game means that we can no longer use quantum chips in the direction of EUV lithography machines to build a completely localized production line in the quantum origin area, from architecture to design and manufacturing, so that the West does not have it"Stuck neck"opportunities.
Just like in the field of automobiles, it is undeniable that traditional fuel vehicles are not as good as fuel vehicles in the United States, Japan, and South Korea, but it doesn't matter, we directly changed the track and embarked on a new track where electric vehicles directly lead the world, and the car is still the same car, but the technology inside is different.
The principle is the same, the traditional chip, we start late, because the recovery will indeed be more tiring, but we can change lanes, in the new lane, we are completely on the same starting line, which gives us the opportunity, after all, on the same starting line of the race, we have never lost.
After all, since 2019, the United States and the West have been losing ground on the semiconductor track, and on the new track, we have also successfully achieved transcendent development.
