Chapter 90 Extreme Ultraviolet Lithography

Different from the performance when he unlocked new exhibits several times before, when Xu Lei saw what appeared in the booth, he was stunned in place.

That's right.

It was the whole person who was stunned.

Because in addition to the huge size of the items in the booth this time, they are also items he is familiar with.

After almost a few seconds of pause, it was considered that he came back to his senses and moved his gaze to the information screen next to him.

Name: extreme ultraviolet lithography machine
Level: zero-level civilization

Evaluation: The most sophisticated integrated circuit production core equipment, the physical limit of silicon-based chips.

Influence: 0/100000
Collection unit: Science and Technology Museum of Cosmic Civilization

"I didn't expect it to be a lithography machine. It seems that what I say this time will make me stay in the Chinese Academy of Sciences for a while!"

At present, all aspects of the country are busy trying to solve the problem of high-end chip manufacturing, and there is still a huge gap between the technical level of overseas countries. Under such a background, the exhibits unlocked happen to be extreme ultraviolet lithography machines, which will definitely make Xu Lei feel stunned.

But accidents are accidents, Xu Lei didn't think too much about it.

After all, as the new owner of this science and technology museum, everything in it is for him, and it is normal to unlock the most suitable exhibits according to the needs of the owner.

It's just that the influence requirement of up to [-] points really made him a little speechless.

Compared with before, it directly doubled by ten times.

I don't know how many chips will be produced to make up enough.

of course.

It is not so easy to manufacture this top-level lithography machine, even with a full set of detailed technologies.

As the most sophisticated equipment, a lithography machine has almost hundreds of thousands of parts. Among them, laser optical lens workbench and objective lens and other parts need to be continuously polished and technically iterated.

Supplies from multiple companies are often required to complete the assembly.

Only relying on the resources owned by future technology, it is tantamount to wishing to manufacture independently.

The best choice is to cooperate with the Chinese Academy of Sciences.

Anyway, now that he has mastered the detailed manufacturing technology of the extreme ultraviolet lithography machine, it doesn't take long to have the cooperation of the Chinese Academy of Sciences.

After solving the core technical problems, he can return to Binjiang City at any time.

When the thought came to this point, Xu Lei immediately made up his mind to master all the detailed technical knowledge of this extreme ultraviolet lithography machine first.

Such a sophisticated device.

The content of technical knowledge included will definitely not be less.

It is estimated that it will take a long time to understand and master it.

next second.

As Xu Lei skillfully clicked on the note in the lower right corner of the information screen, a massive amount of content filled his field of vision in an instant. If it weren’t for the science and technology museum ignoring the passage of time and keeping people in the state of just entering, it is estimated that just seeing these Dizziness.

Relying on the previous experience of absorbing information and knowledge, this time Xu Lei can be said to be familiar with the road, and he quickly entered the state.

And when the content on the information screen gradually entered Xu Lei's mind through visual transmission and quickly merged, Xu Lei finally understood the evaluation of the exhibit.

According to Moore's Law, as the size of the chip decreases, the influence of quantum effects intensifies, and silicon-based chips begin to gradually reach the physical limit.

As for this physical limit, it is theoretically 1 nanometer.

However, due to the limitations of materials, the basic production of chips with a 3-nanometer process has come to an end.

However, this top-level lithography machine in the museum has the ability to produce 1-nanometer chips, and only needs the assistance of special materials.

In other words, once this top-level lithography machine is manufactured, the domestic development in the semiconductor field will directly jump into the top ranks, changing from passive to active.

Even if overseas companies want to produce high-standard chips, they need to make them here.

Otherwise, it will be abandoned by the market.

We must know that the current mainstream technology for overseas chip production is still based on 7nm, and even the most advanced fab, Tengxiang Electronics, has just planned to build a 5nm fab, and there is still a long way to go before realizing the large-scale production of 3nm chips. way to go.

Not to mention the physical limit of 1nm chips.

It is also worth mentioning that the exhibits unlocked in the museum so far are all from Level [-] civilization.

Although the technology products in the zero-level civilization are relatively close to the level on the Blue Star, and there will be no situation that cannot be manufactured, it will inevitably make people feel a little regretful.

Mainly as a life in a zero-level civilization, who doesn't want to feel the technological power from a higher civilization.

However, based on Xu Lei's detailed understanding of the museum, it is likely that the collection of high-level civilization exhibits is not in the hall, but stored in the upper space.

However, no matter how Xu Lei searched, he still couldn't find the entrance to the upper floor, so he had to give up in the end.

However, according to the museum's requirements for unlocking new exhibits, Xu Lei speculates that the total number of influences may need to reach a certain standard before the entrance to the upper space will appear.

He believes that as more and more exhibits are unlocked, sooner or later you will encounter technological products of advanced civilization.

By that time, the situation in the world grid will undergo earth-shaking changes.

It's not the kind of small fights that are happening now.

……

I don't know how long it has been, until Xu Lei heard a voice calling himself next to his ear, and then he controlled his consciousness and temporarily left the museum.

"President Xu, Dean Yang is waiting for you outside."

As soon as Xu Lei opened his eyes, a beautiful face immediately occupied his field of vision.

It was his assistant Chen Shihe.

After regaining his senses, Xu Lei stretched out his hands and rubbed his slightly stiff face, before getting up and walking outside.

It just so happened that he was also looking for an opportunity to discuss with Yang Senping about cooperating in the manufacture of top-level lithography machines.

On the contrary, Chen Shihe saw Xu Lei's performance and thought that he hadn't had a good rest, so he quickly suggested: "Mr. Xu, why don't you rest a little longer, and I'll go and talk to Dean Yang."

"fine."

"Let's go out."

No matter how long you stay in the museum, it will not affect your physical condition outside, so Xu Lei directly vetoed Chen Shihe's proposal.

Saying that, he opened the door and walked out.

Seeing this, Chen Shihe had no choice but to follow up quickly so that he could keep track of Xu Lei's situation at any time.

In the morning, under the leadership of Yang Senping, he visited several technical laboratories. In the afternoon, Xu Lei also showed his familiarity. He would communicate with researchers and academicians when he encountered something he was interested in.

Learn more about it.

Xu Lei knows that the current difficulties of domestic lithography machines are mainly in the laser objective lens and special composite materials, as well as the key high-end photoresist.

The working principle of the lithography machine is to first emit light through the laser, and then enter the photomask table under the action of the energy controller and beam shaping device after correction, and then enter the exposure table under the projection of the objective lens system, because at this time the wafer is smeared Lithography machines are light-sensitive, and ultraviolet light will etch circuits on the wafer.

Among them, the top extreme ultraviolet and high-end immersion technology will be used.

The laser is responsible for the generation of the light source, which has a decisive impact on the manufacturing process, and the wavelength band of the light source needs to be kept at a suitable length.

Overseas lithography machines with objective lens systems need to rely on Zeiss optical lenses from Germany.

As for special composite materials and photoresists, they are monopolized by Neon Country.

It can be imagined how difficult it is to have these technologies at the same time.

If Xu Lei hadn't obtained a full set of detailed technologies for top-level lithography machines, I really don't know how long it would take to overcome all these problems.

But perhaps because of tacit understanding, neither Xu Lei nor Yang Senping mentioned the development of lithography machines during the process.

It's like it's completely forgotten.

It wasn't until nearly five o'clock in the afternoon, when Xu Lei and others were about to return to the hotel, that Yang Senping couldn't bear to talk about what he said in the morning again.

"Mr. Xu, you are also aware of the progress of research and development on lithography machines in China. We are in urgent need of talents to join, so I sincerely hope you can think about it."

"As long as you agree, I will try my best to satisfy any questions."

Xu Lei, who had been waiting for this sentence for a long time, raised his mouth slightly when he heard the sound, and then changed his words in the morning and agreed: "Dean Yang, I can stay temporarily to participate in the research and development of the lithography machine."

"You agree?"

"Aren't you lying to me on purpose?" Hearing this result suddenly, Yang Senping was pleasantly surprised, and quickly confirmed it.

There was still disbelief in his words.

In fact, after receiving Xu Lei's answer in the morning, Yang Senping was basically sure that his idea could not be realized, and only asked again out of the importance he attached to Xu Lei.

But he never expected that Xu Lei would suddenly give him such a big surprise.

But Xu Lei definitely has requirements for this.

Almost as soon as Yang Senping's voice fell, he took over the conversation and said, "It's just that I have two requirements that you need to meet first."

"Require?"

"You can ask for whatever you want." Yang Senping replied without any scruples.

When Xu Lei heard Yang Senping say this, he naturally had nothing to worry about, so he immediately stated his two requirements.

"First of all, I want to be the general manager of the project."

"The other thing is to abandon the research you are doing now, and start over according to my research direction."

Yang Senping, who was originally full of anticipation, became serious after hearing these two requests, as if he did not expect Xu Lei to make such a request.

If Xu Lei is really capable of overcoming the technical barriers of high-end lithography machines, there is no problem in appointing him as the general manager of the project. What's more, with Xu Lei's technical achievements, I believe that no one in the academy will have doubts or dissatisfaction.

But these years they have put so much effort into the research of lithography machines.

Especially with the assistance of smart assistants and just made technological breakthroughs, if you choose to overturn and start over, no matter how you look at it, it is really unacceptable.

It is equivalent to negating all previous efforts.

So after a little hesitation, Yang Senping still asked out the worries in his heart.

"The manufacturing technology of lithography machines is changed from generation to generation. Why do you need to overthrow them all? Do you have a better technical solution, Mr. Xu?"
