My science and technology museum

Different from his previous behavior when unlocking new exhibits, when Xu Lei saw what appeared in the booth, he was stunned.

That's right.

The whole person was stunned.

Because in addition to the large size of the items in the booth this time, they were also items he was familiar with.

After pausing for a few seconds, he finally came to his senses and turned his attention to the information screen next to him.

Name: Extreme UV lithography machine

Level: Zero level civilization

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

Influence: 0/100000

Collection unit: Universe Civilization Science and Technology Museum

"I didn't expect it to be a lithography machine. It seems that no matter what, I will be asked to stay at the Chinese Academy of Sciences for a while this time!"

At present, all parties in China are extremely busy trying to solve the problem of high-end chip manufacturing, and there is still a huge gap between the technical level and overseas technology. Under such a background, the exhibit unlocked happens to be an extreme ultraviolet lithography machine, which will definitely make Xu Lei feel... stunned.

However, an accident was an accident, and Xu Lei didn't think too much about it.

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

But the influence requirement of up to 100,000 points really left him a bit stunned.

It has increased tenfold compared to before.

I don’t know how many chips will be produced to make up for it.

certainly.

It is not easy to manufacture this top-level photolithography machine, even if you have a complete set of detailed technologies.

As the most sophisticated equipment, a photolithography machine has almost hundreds of thousands of parts. Among them, components such as the laser optical lens table and objective lens require continuous polishing and technical iteration.

It often requires supplies from multiple companies to complete assembly.

With the resources available to future technology alone, trying to independently manufacture it is tantamount to wishful thinking.

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

Anyway, now that he has mastered the detailed manufacturing technology of extreme ultraviolet lithography machines, it will not 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.

When his thoughts reached this point, Xu Lei immediately made up his mind and prepared to master all the detailed technical knowledge related to this extreme ultraviolet lithography machine.

Such sophisticated equipment.

It contains absolutely no shortage of technical knowledge.

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

The next second.

As Xu Lei skillfully clicked on the annotation in the lower right corner of the information screen, a massive amount of content instantly filled his field of vision. If the Science and Technology Museum didn't ignore the passage of time and could always keep people in the state they just entered, I would probably have just seen these. Dizziness.

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

And when the content on the information screen was gradually transmitted into Xu Lei's mind through visual transmission and quickly integrated, Xu Lei finally understood the evaluation of the exhibits.

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

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

However, due to material limitations, the basic production of chips with 3 nanometer technology has come to an end.

But this top-level photolithography machine collected by the museum has the ability to produce 1-nanometer chips, and it only needs the assistance of special materials.

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

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

Otherwise, they will be abandoned by the market.

We must know that the current mainstream process of overseas chip production is still based on 7nm. Even the most advanced wafer factory, Semiconductor Manufacturing Co., Ltd. has just planned to build a 5nm wafer factory. It is still far away from realizing the large-scale production of 3nm chips. Way to go.

Not to mention the physical limit of 1 nanometer chip.

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

Although the technological products in the zero-level civilization are relatively close to the level on Blue Star, there will be no situation where they cannot be manufactured, but it is inevitable that people will 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, through Xu Lei's detailed understanding of this museum, it is very likely that the collection of advanced civilization exhibits are not in the hall, but are stored in the space above.

However, no matter how Xu Lei searched, he never found the entrance to the upper level, so he had to give up in the end.

However, based on the museum's requirements for unlocking new exhibits, Xu Lei speculated 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 he will encounter technological products of advanced civilizations.

By that time, the world situation will have undergone earth-shaking changes.

It's not a small fight like now.

…

I don't know how much time passed until Xu Lei heard a voice calling him, and then he controlled his consciousness and temporarily left the museum.

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

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

It was his assistant Chen Shihe.

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

It just so happened that he was also looking for an opportunity to discuss cooperation with Yang Senping in manufacturing top-level photolithography machines.

However, Chen Shihe saw Xu Lei's behavior and thought that he had not rested well, so he quickly suggested: "Mr. Xu, why don't you take a little more rest, and I'll go talk to Dean Yang."

"fine."

"Let's get out."

No matter how long you stay in the museum, it will not affect the state of your body outside, so Xu Lei directly rejected Chen Shihe's proposal.

Then he opened the door and walked out.

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

Since he visited several technology laboratories in the morning under the leadership of Yang Senping, Xu Lei showed that he was very familiar with the technology in the afternoon, and he would go out of his way to communicate with scientific researchers and academicians when he encountered something he was interested in.

Learn more by.

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

The working principle of the photolithography machine is that the laser emits light first, and after correction, it enters the photomask stage under the action of the energy controller and beam shaping device, and then comes to the exposure stage under the projection of the objective lens system, because at this time, the wafer is coated with The photolithography machine is photosensitive, and ultraviolet light will etch circuits on the wafer.

Top-notch extreme ultraviolet and high-end immersion technologies will be used.

The laser is responsible for generating the light source, which has a decisive impact on the manufacturing process. The light source band needs to be maintained at a suitable length.

The objective lens system of overseas lithography machines relies on German Zeiss optical lenses.

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

You can imagine how difficult it is to have these technologies at the same time.

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

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

It's like completely forgetting it.

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

"Mr. Xu, you are also aware of the progress of domestic research and development on lithography machines. We are in urgent need of talents, so I sincerely hope you can consider it carefully."

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

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

"You agreed?"

"Aren't you deliberately lying to me?" Yang Sen was pleasantly surprised when he suddenly heard the result and quickly confirmed it.

There was still disbelief in his words.

In fact, after getting Xu Lei's answer in the morning, Yang Senping was basically sure that his idea could not be realized, so he asked again out of concern for Xu Lei.

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

But Xu Lei must have requirements for this.

Almost as soon as Yang Senping's voice fell, he took over 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 what Yang Senping said, he naturally had nothing to worry about, and immediately made his two requests.

"First of all, I want to be the overall person in charge of the project."

"The other thing is to abandon the research you are currently conducting and start over based on my research direction."

Yang Senping, who was originally full of expectations, suddenly became serious after hearing these two requests. It seemed that 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 would be no problem in letting him serve as the general manager of the project. Moreover, with Xu Lei's technical achievements, I believe no one in the institute will have any doubts or dissatisfaction.

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

Especially with the help of smart assistants and recent technological breakthroughs, if we choose to overthrow it now and start over again, it will be really unacceptable from any aspect.

It is equivalent to negating all previous efforts.

So after a slight hesitation, Yang Senping asked about his worries.

"The manufacturing technology of photolithography machines has been changing from generation to generation. Why do we need to overthrow everything and start over? Do you, Mr. Xu, have a better technical solution?"
