Unlike the performance when unlocking new exhibits several times, when Xu Lei saw something emerging in the booth, he was stunned.

That's right.

He was stunned.

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

After almost a few seconds of pause, I came back to my senses and moved my eyes to the information screen next to me.

Name: Extreme UV lithography machine

Level: Zero-level civilization

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

Influence: 0/100000

Collection unit: Cosmic Civilization Science and Technology Museum

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

At present, all aspects of the country are busy solving the problem of high-end chip manufacturing, and there is still a huge gap in the technology level overseas. In such a context, the exhibits unlocked happen to be extreme ultraviolet lithography machines, which will definitely surprise Xu Lei.

However, Xu Lei didn't think too much about the accident.

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

It was just a requirement of influence of up to 100,000 points, which really shocked him.

It's ten times more than before.

I don't know how many chips to produce to make up.

certainly.

It is not that easy to manufacture this top-level lithography machine, even if it has a full set of detailed technology.

As the most precise equipment, a lithography machine has almost hundreds of thousands of parts, including laser optical lens workbench and objective lens parts, which require continuous polishing and technical iteration.

It often requires supply from multiple companies to complete assembly.

It is a dream to create it independently based on the resources owned by future technology.

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

Anyway, he has mastered the detailed manufacturing technology of extreme ultraviolet lithography machines, and it doesn’t take long with the cooperation of the Chinese Academy of Sciences.

Once the core technical problems are solved, he can return to Binjiang City at any time.

After the idea came to this point, Xu Lei immediately made up his mind and prepared to master all the detailed and relevant technical knowledge of this extreme ultraviolet lithography machine first.

Such a sophisticated equipment.

The technical knowledge content is definitely not missing.

It will probably take a long time to understand and integrate it.

Next second.

As Xu Lei skillfully clicked on the comments in the lower right corner of the information screen, a huge amount of content instantly filled his vision. If it weren't for the ignoring the passage of time in the science and technology museum and being able to keep people in the state they just entered, I would probably be dizzy just to see these.

Relying on the experience of absorbing information knowledge in the previous few times, Xu Lei can be said to be familiar with the situation this time and soon entered the state.

When the content in the information screen was gradually transmitted into Xu Lei's mind through visualization and quickly integrated, Xu Lei finally understood the evaluation of the exhibit.

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

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

However, due to material limitations, the chips that basically produce 3-nanometer process have come to an end.

However, this top lithography machine collected by the museum has the ability to produce 1nm chips, and only needs the assistance of special materials.

In other words, once this top lithography machine is manufactured, domestic development in the semiconductor field will directly jump into the top ranks and take the initiative from the original passiveness.

Even overseas companies want to produce high-standard chips, they need to get the foundry here.

Otherwise, it will be abandoned by the market.

You should know that the current mainstream process of overseas chip production is still mainly 7 nanometers. Even the most advanced fab, Kuoji Electric, has just planned to build a 5-nanometer fab, and there is still a long way to go before achieving large-scale production of 3-nanometer chips.

Not to mention the physical limit 1nm chip.

It is also worth mentioning that the exhibits unlocked by the museum so far are all from level zero civilizations.

Although the level of technology products in the zero-level civilization is relatively close to that on Blue Star, 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 higher civilizations?

However, through Xu Lei's detailed understanding of the museum, the collection of exhibits of higher civilizations are likely not in the hall, but in the space above.

However, no matter how Xu Lei looked for it, he never found the entrance to the upper floor, so he had to give up in the end.

However, according to the museum's requirement to unlock new exhibits, Xu Lei speculated that the total number of influences may need to meet a certain standard before an entrance to the upper space will appear.

He believes that as more and more exhibits are unlocked, he will sooner or later encounter technological products from higher civilizations.

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

It's not like this kind of small fight now.

...

I don’t know how long it has been, but it was not until Xu Lei heard a voice calling him in his ear that he controlled his consciousness and temporarily left the museum.

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

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

It was his assistant Chen Shihe.

After coming back to his senses, Xu Lei immediately stretched out his hands and rubbed his slightly stalemate face, and then prepared to get up and walk outside.

It just so happened that he also wanted to find an opportunity to discuss cooperation with Yang Senping on the manufacturing of top lithography machines.

However, when Chen Shihe saw Xu Lei's performance, she thought he had not had a good rest, so she quickly suggested: "Mr. Xu, why don't you take a little longer? I'll talk to Dean Yang."

"fine."

"Let's go out."

No matter how long he stays in the museum, it will not affect his physical condition outside, so Xu Lei directly rejected Chen Shihe's proposal.

As he said that, he opened the door and walked straight out.

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

Because he visited several technical laboratories under Yang Senping's guidance in the morning, Xu Lei was familiar with the situation in the afternoon. When he encountered something he was interested in, he would deliberately communicate with scientific researchers and academicians.

Learn more.

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

The working principle of the lithography machine is to first emit light through the laser, enter the photomask table under the action of the energy controller and the beam forming device, and then project it on the objective lens system to the exposure table. Because the photolithography machine is applied to the wafer at this time, the photosensitive photolithography machine will be applied to the wafer, and ultraviolet light will etch the circuit on the wafer.

Among them, top-level extreme ultraviolet and high-end immersion technologies will be used.

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

Overseas lithography machines for objective lens systems need to rely on Germany's Zeiss optical lens.

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

To have these technologies at the same time, the difficulty can be imagined.

If Xu Lei had not obtained the full set of detailed technology of top lithography machines, I really don’t know how long it would take to solve all these problems.

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

It's like completely throwing it away.

It was not 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 help but talk about what he said in the morning again.

"Mr. Xu, you have also known the progress of domestic research and development in lithography machines. We are urgently in need of talents, 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, immediately raised his lips slightly when he heard the sound, and then changed his morning speech and agreed: "Director Yang, I can stay and participate in the research and development of lithography machines for the time being."

"Did you agree?"

"Aren't you lying to me on purpose?" After hearing this result, Yang Senping was surprised and quickly spoke out to confirm.

There was still disbelief in the words.

In fact, after receiving Xu Lei's answer in the morning, Yang Senping was basically sure that his idea was impossible to realize. He asked again out of his importance to Xu Lei.

But I never expected Xu Lei to suddenly give him such a big surprise.

However, Xu Lei must have some 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?"
