Chapter 2187: New Mission
"There are too many questions to ask, and I don't know how to start!" The experts sighed. High-end photolithography machines are called the flowers of the modern optical industry, and their manufacturing is so difficult that there are only a few companies in the world. able to manufacture.
According to the type, it can be divided into contact type, proximity type and projection type, and high-end projection lithography machines can be divided into two types: step projection and scanning projection lithography machines, and the resolution is usually between seven nanometers and several microns. , High-end lithography machines are known as the most sophisticated instruments in the world, and the price of the most advanced lithography machines is in units of 100 million US dollars.
Moreover, subject to the technical blockade of European and American countries, China can’t buy it even with money. Even if it tries its best to overcome difficulties and order one or two units, it is often a product with backward technology. Inexplicable fire and other reasons delay or cancel the delivery.
There are also manufacturers in China that are developing and manufacturing lithography machines, but there is still a big gap in technology compared with top European and American companies such as ASML. Foreign countries have reached the processing level of four nanometers. It is only 22 nanometers, which cannot meet the demand at all.
"The model adopted by this design drawing is different from that of ASML, Nikon, and Canon, and it is also different from what we are developing now. Although it seems theoretically feasible at present, it will take a lot of time to fully understand this model. Quite a long time! Not to mention producing samples."
There are more than 80,000 parts inside a lithography machine, and the weight is 180 tons, and the parts of the lithography machine are not all made in one country, because some of them are Japanese optical technology, and some are German mechanical technology; so Aspen Mai once said that even if the design drawings were given to you, you would not be able to manufacture them.
Because according to the current level of technology, if you want to manufacture an advanced lithography machine, you must use the most advanced technology products from multiple countries. ASML's lenses use German Zeiss products; these European and American companies are worth mentioning. Yes, it is not generally difficult for Chinese companies to purchase these products.
"In any case, these materials also point us to a brand new path. As long as we can understand these things thoroughly, we will not be stuck by European and American countries!" Maybe someone who knows about the controllable nuclear fusion and the Quin-jet fighter project The reason is that the leader seems to be full of confidence in this blueprint.
"If we can understand it thoroughly, then we can achieve 100% localization of lithography machine manufacturing. I see that the components used here are also different from ASML, Nikon, and Canon, and there is no patent barrier. The problem, what we have to worry about now is whether our precision processing level can reach the standard!" The expert nodded, indeed, it is not easy to manufacture a photolithography machine with superior performance according to this drawing, but with this drawing , can definitely avoid many detours.
"If you have any questions about that part, just write it down, and you should be able to get a satisfactory answer!" They can even manufacture miniature controllable nuclear fusion reactors, so it is definitely not a problem to manufacture these parts. Hey, what a pity.
If only he could provide us with a sample of a photolithography machine like he provided a sample of a micro controllable nuclear fusion reactor.
I don't know if I ask him in the email, will he agree? No matter how advanced the lithography machine is, it must not be more difficult to manufacture than a miniature controllable nuclear fusion reactor, right? The leader was thinking about it in his heart, but he didn't plan to write this meaning in the email for the time being. According to the previous situation, if there was any, he might give it directly. Good question, lest people say that we are not greedy enough.
Several experts got together to discuss and finally reached an agreement, "Let's talk about the big aspects first. We still have a lot of questions about the theory. If the theory is not clear, the details are even more impossible to talk about!"
"You are responsible for the professional work. You discuss and discuss first, and list all the most important issues!" The leader arranged a meeting room for them, and brought in all the equipment they needed, so that they could work without distraction.
After a day and night of discussion, these experts came up with the first batch of questions, and then the leaders sent these questions to Shen Long. The research on lithography machines has already had a solid foundation, so it seems that the time to produce the first prototype is earlier than I expected."
Shen Long crossed his fingers, moved his fingers, and then began to type with a crackling sound, answering the questions of these experts one by one. Through these questions, he also knew the level of these experts, and he knew what to say when answering the questions. to what extent.
It took only half an hour for Shen Long to answer all the questions, and the typing keyboard had already started to smoke. There was no way, Shen Long's typing speed was really too fast.
After careful inspection, Shen Long sent them the email. With Bai Ze helping to cover it up, Shen Long was not afraid that someone would find him through the email.
Those experts went to bed after asking the questions. From their point of view, the questions they listed were extremely difficult to answer. Even if the other party was very familiar with this field, it would take several days to complete the answer. However, they did not expect that, Less than an hour later, the other party's reply came.
They were already tired after working all day and night, but when they saw this email, they immediately felt relieved, gathered around the computer, studied the reply word by word, and exclaimed, "It turns out that this is the case. , Why didn’t I think of it, and this method can be used to solve it?”
"This conclusion is very innovative. Neither ASML nor Nikon has set foot in this field. This time we can get ahead of them!"
"Understood, I understand, this method can indeed greatly increase the yield rate, which is even more powerful than ASML's latest product!"
"This kind of ultraviolet light source is indeed more stable, the energy distribution is more uniform, and the fault tolerance rate is higher, and the requirements for production operations are lower, which is really amazing."
In this way, the experts studied the emails day and night, and after the research, they conducted experiments while asking new questions, while Shen Long, as before, communicated with them at the speed of one email per week.
After sending emails back and forth about three times, the system notification sounded again in Shen Long's mind, and a new task came to him.
