For a long time, lithography machines have been a threshold for our technological development. At present, only ASML can produce the most advanced lithography machines in the world, and this Dutch giant once arrogantly declared that even if the lithography machine drawings are given We can't produce it!
But what is sad is that ASML is really telling the truth. The most advanced lithography machine is the jewel in the history of human industry. It is a collection of scientific and technological masterpieces from the entire Western world. It is indeed not completely developed by scientific researchers in a certain country. come out. But now, a very strange thing has happened-ASML wants to give our company a lithography machine!
In the third CIIE, the lithography machine giant ASML exhibited its own DUV lithography machine. They brought a very complete DUV lithography machine program this time, which can produce 7nm and above process chips. Moreover, the CFO of ASML also stated that it would export DUV lithography systems to SMIC and other customers without an export license (country M).
ASML wants to send a 7nm lithography machine, which seems to be a good thing, but in the long run, many scholars and netizens do not think so. Because in fact, the Chinese Academy of Sciences has already developed the lithography machine in the past nine years and has kept up with the international advanced manufacturing process, but later it was also because it felt that it was cheaper to buy from abroad, so it gave up the domestic lithography machine. , As a result, everyone knows that as long as they "stuck their necks", we will be helpless.
And now, the Chinese Academy of Sciences has officially announced the entry of lithography machines, so we have a better understanding that we must not give up self-research because of buying. Many netizens also said: Huawei cannot be saved by buying, and we must master the core technology In your own hands!
Regarding this matter, Zhang Zhaozhong’s words actually pierced the mentality of the western science and technology circles: if they cut off our chips for three years, they won’t have to export them again after three years. The streets in China are everywhere! This is obviously also a problem that ASML is aware of, so he hastily stepped up and took the initiative to sell us the lithography machine, but it was to make us fall into the trap of "buying better than making".
And one thing we must pay attention to is that the lithography machine they are going to sell to us is not advanced, only the DUV lithography machine. The wavelength of the liquid immersion DUV lithography machine is 193nm, which requires multiple exposures to reach the 7nm process. , But every exposure will greatly increase the cost!
In contrast, their most advanced EUV lithography machine uses a light source with a wavelength of 13.5nm. Only in this way can chips below 10nm be produced more effectively. So, what ASML gives us is not a treasure, it just wants us to "make do with it" first, and it is best to slow down the development speed.
However, we naturally cannot make the same mistake a second time. This time, even if we buy it first, our self-study will definitely not stop!
