Recently, many ** said that wafer factories in Chinese mainland are working with a domestic mobile phone giant to use DUV deep ultraviolet technology to manufacture 5nm chips, and specific chips may be launched soon.
Although the news is not known to be true or false, but combined with the statement of Lin Benjian, the father of the immersion lithography machine some time ago, it is still reliable, Lin Benjian said that the immersion lithography machine can make 5nm chips, but the cost is a bit high, and it needs 4 times.
In fact, many professionals have shown that the process level limit of the immersion lithography machine is by no means 7nm, or even 5nm, and theoretically even 2nm chips can be made. Lin Benjian also expressed a similar view, saying that the immersion DUV lithography technology can achieve up to six lithography modes and can achieve more advanced processes.
However, under the advanced process, DUV technology requires more heavy technology, which will significantly reduce the yield, reduce the manufacturing efficiency, and then increase the cost.
Therefore, in the case of being able to buy an EUV lithography machine, when it reaches 7nm, it will be manufactured by EUV violet light, which is more economical and effective than using DUV, because it does not need to be multi-**, has a high yield and lower cost.
But everyone knows that EUV lithography machines cannot be bought in China, so no matter how difficult and costly it is, you can only use DUV lithography technology to manufacture more advanced technology than 7nm, which is no way.
Therefore, as reported by these ** reports, it is not outrageous to take DUV technology and make 5nm chips, it is very possible, and even if it is rumored that one day it is rumored to use DUV to make 3nm chips, it is also possible, not bragging.
Of course, the 5nm chip has not yet been manufactured, but as long as it is made, it will declare that the US sanctions have basically failed. Because the U.S. policy last year was to lock China's logic chips at 14nm.
But this year, a chip equivalent to 7nm came out, and then if there is a chip equivalent to 5nm, of course, it means that this blockade has completely failed.
More importantly, at present, the world's chips using sub-5nm processes are only Apple's A17 series chips, M3 series chips, and Qualcomm and MediaTek's latest SoC, in addition to these chips, all other chips use 5nm or more mature processes, and 5nm and more mature process chips account for more than 97%.
So from the perspective of market share, as long as the chips with the 5nm process can be manufactured, it means that at least 97% of the world's chips can be manufactured, and only 3% of the chips cannot be manufactured. Under such circumstances, do we still need to worry about blockade and suppression?
Therefore, the hope of this 5nm chip is true, as long as it is launched, it is estimated that the blockade of the United States will be completely reduced to a joke, and there will be no need to exist, which also means that China's chip industry has officially taken off, what do you think?
