We all know that the precision of the chip now is that the smaller this number, the higher the precision. From 8 nm to 5 nm, they have been communicating with the two-nanometer chip they have studied, but what should they do after two meters? Because it reaches the level of two nanometers, the accuracy requirement of this mask aligner is already quite high. If we want higher accuracy, we can't count on this thing. If we really want to count on this kind of mask aligner, we must make greater technological breakthroughs. So how can we get on the road after two nanometers? At present, no manufacturer has a very good method, but they are trying to break through, because the success rate of two-nanometer chips can not be guaranteed.
Domestic mask aligner recently rolled off the production line, but the accuracy of domestic mask aligner is very low, 28 nm. This accuracy may be useful if it is improved by three or four times, but it is still useless in the short term. Our expectation for mask aligner now, if it is rational consideration and realistic planning, will gradually reach the chips used in the daily low-end market in the next two to three years and reach the terminal market in five years. 10 has reached the top of the world, which is quite good, because mask aligner's manufacturing is not that simple, and we can't compare with building an atomic bomb. The two are not the same thing.
The future chip manufacturing must be studied and considered through various channels, but in the final analysis, it is all to describe more effective operation in a fixed area. Of course, this requirement is very high now, but with the current technology in mask aligner, it is obviously not enough to make more breakthroughs in the future. Actually, we don't have to think so much at home. Now it is only a bright future for China to consider how to go after two nanometers. Because of the current domestic chip manufacturing technology, while ensuring the success rate and controlling the cost, it can't achieve seven nanometers, let alone higher accuracy. There is still a long way to go.
If our chips can really be localized on a large scale in the next 5~ 10 years, it is very likely that our electronic products will gradually stand up and do not need to rely on foreign countries continuously. By then, the prices of these electronic products can be further reduced. Not only mobile phones and computers, but also smart cars are similar, because the chip has high precision, which can be applied not only to mobile phones, but also to other products.
