Insurmountable barriers
In the competition with Western technology blockade, the high-end lithography machine equipment has once become an insurmountable barrier for domestic technology companies. The Dutch ASML is the only manufacturer in the world that can manufacture EUV lithography machines, but Its equipment contains nearly 30% of American technology and parts. Although it has shown good in the domestic market several times, it has never been able to obtain a shipping license.
In the era of intelligence, the chip can be called the "brain", especially for technology companies such as Huawei that have made great contributions to my country's 5G business, its importance needless to say. To solve the chip problem, it is necessary to leapfrog the lithography technology. To this end, the Chinese Academy of Sciences took the lead, and President Bai Chunli said:
included lithography and other card-neck technologies in the urgent scientific research task list of the academy.
Facing the importance of Chinese Academy of Sciences and domestic chip companies to the field of lithography, foreign media are not optimistic. At the time of the CIIE, ASML said that even if you give you the manufacturing drawings of the lithography machine, you may not be able to make it.
Even the founder of TSMC Zhang Zhongmou waited to pour cold water more than once. The research and development of lithography machines is no less difficult than the atomic bomb. The limitations of tens of thousands of parts and assembly technology are very difficult for the whole country. Technology can only be down-to-earth, and there is no corner overtaking.
Perhaps, the development of domestic chips is stuck in the link of lithography machine, which is the result that Western technology blockade most wants to see.
Chinese Academy of Sciences presents scientific research results
However, the Chinese Academy of Sciences recently announced an important scientific research result, which amazed those who are self-righteous. Z14z "Isn't it a good lithography machine, why did you bypass it?", American scientist Reluctantly said that this is too fast. After 5G technology, China will lead the world in another field.
At the international graphene innovation conference held a few days ago,
Chinese Academy of Sciences showed the developed 8-inch graphene wafer for the first time. This result reached the top level in terms of quality and size.
Perhaps many people are relatively new to graphene wafers, and they may even ask, what does this have to do with lithography machines?
First of all, we must be clear that the important raw material for carbon-based chips on graphene wafers. The 21st century is the carbon era. In this field, almost the world is seeking breakthroughs in raw materials, because this is the only way to make carbon-based chips. , And my country’s Chinese Academy of Sciences is the only scientific research team that has accomplished such an achievement. The chips manufactured by the
lithography machine are silicon-based chips. With the same process, the performance of carbon-based chips is at least 10 times higher than that of silicon-based chips. More importantly, silicon materials are the products of the last century. Improved, silicon-based chips are accurate to 5nm and 3nm, which has approached the physical limit. In other words, the development of
chips has come to the stage of re-selecting semiconductor materials. The 8-inch graphene wafers brought by the Chinese Academy of Sciences are undoubtedly the best quality. Carbon-based chip raw material . There is a more important reason why
surprised the foreign media. Based on the performance of graphene,
bypasses the complicated high-end lithography technology in manufacturing. It can also be understood as the requirement for lithography technology. Not as demanding as 5nm silicon-based chips. Z15z
is written at the end
Although the lithography machine is very important, it is an indisputable fact that the silicon-based chip has reached the ceiling. If we continue to study high-end lithography technology with a nationwide effort, even if we succeed, by then, the silicon-based chip may It is no longer indispensable.
's research and development of carbon-based chips is equivalent to the fact that we have already begun to run in the new era. From passive beating to formulating rules, the Chinese Academy of Sciences has officially launched the sword, because once it falls behind, the price to be paid is too great. What do you think of this
