My science and technology museum

Yang Senping and his colleagues’ research on domestic lithography machines has developed from the initial millimeter process to micron, and now to the nanometer level.

But it has always been far behind in overseas technology.

Now even if the Chinese Academy of Sciences has made a major technological breakthrough, it has only reached the 28-nanometer level.

It is far from overseas 5nm chips.

After all, every time the manufacturing specifications of chips are improved to a small level, the difficulty of research and development increases several times. If we still conquer the technology in the original way, I am afraid that by the time domestic lithography machines can produce 14nm or 7nm chips, people will have already achieved 3nm. Craftsmanship.

You will still lag behind others.

That's why Xu Lei asked Yang Senping to completely overturn the previous research and development progress.

Start directly from the physical limit of 1 nanometer for silicon-based chips.

In this way, domestic top-level lithography machine technology will gain dominance in the global semiconductor market, and there will be no need to worry about being overtaken again for a long time to come.

Because Xu Lei studied the technical knowledge involved in the extreme ultraviolet lithography machine exhibits in the museum, he found that in order to produce 1-nanometer chips, the physical limit of silicon-based chips, a relatively special metal is needed.

And it happens that this metal has the largest reserves in China.

With this bargaining chip, even if overseas photolithography machines are updated to the top level, they can only produce 3-nanometer chips at most.

As for carbon-based chips, another path in the chip field.

Although the performance of carbon-based chips is much better than that of silicon-based chips under the same specifications, it still requires photolithography machines for production. Coupled with the price of materials and the fact that it is still in the laboratory stage, whether it can achieve large-scale mass production is completely unclear. unknown.

However, Xu Lei also knew that it might not be easy to convince Yang Senping without providing some real materials.

So when faced with Yang Senping's inquiry, he immediately explained: "The technology you are currently researching is too backward. Even if there are new breakthroughs, it will only catch up with the overseas companies in Shanghai."

"In this situation of equal skill levels, they would still have an inherent advantage."

"It's not conducive to our development in the semiconductor industry."

"So if you want to do it, then go straight to the stomach and reach the physical limit of silicon-based chips."

"Backward technology is destined to be abandoned by the times. Dean Yang does not need to feel bad at this time. I believe you will be happy with today's choice soon."

If Yang Senping was more solemn when faced with the two requests made by Xu Lei just now, then at this moment his heart was full of shock, and his eyes widened subconsciously as if an earthquake had occurred.

At the same time, the brain is also working rapidly.

Physical limits?

And why did Xu Lei suddenly become so confident?

Could it be...

Thinking that Xu Lei was still trying his best to shirk the invitation in the morning, but now he is threatening to directly enter the physical limits of silicon-based chips, there must be some reasons for this.

In addition, Xu Lei rushed here from Binjiang City so happily this time, and he may have already conquered the manufacturing technology of top-level photolithography machines.

The original intention of this trip was to cooperate with the Chinese Academy of Sciences to manufacture photolithography machines.

"He didn't agree directly this morning because he was worried that I was unwilling to give up my current research results and wanted to test my sincerity in cooperation."

"That's right."

"Definitely."

As Yang Senping's thoughts stopped here, he suddenly felt a sense of enlightenment.

The heart that had been beating for decades in his chest became even more violent.

If Xu Lei really masters the manufacturing technology of top-level photolithography machines, let alone abandoning the current research results, there will be no problem in starting over.

After figuring out the key, Yang Senping finally showed his courage to become the dean.

Make decisions on the spot.

"Mr. Xu."

"No matter what, please believe in our determination to develop domestic lithography machines."

"I will write a detailed report immediately and apply to the higher authorities to establish a special scientific research group to develop top-level lithography machines for 3-nanometer chips."

"And you will be in charge."

Seeing that Yang Senping suddenly figured out something and changed his attitude, although Xu Lei was a little surprised, he was more relieved.

At least it saved him a lot of energy and time.

But after Yang Senping finished speaking, Xu Lei shook his head at him with a smile.

"I'm not talking about lithography machines that produce 3-nanometer chips."

"No?" Yang Senping was stunned.

According to the physical limit mentioned by Xu Lei, the industry recognized it as a 3-nanometer chip. Yang Senping did not think that he had misunderstood anything.

After all, due to material limitations, the theoretical 1-nanometer silicon-based chip cannot be developed.

But just when Yang Senping was surprised and ready to ask Xu Lei, a familiar voice suddenly sounded in his ears.

"What I want to develop this time is a top-level photolithography machine that can produce 1-nanometer chips."

"1 nanometer, this is simply impossible!"

Hearing what he didn't dare to think about actually come from Xu Lei's mouth, Yang Senping subconsciously exclaimed that he really couldn't believe that Xu Lei could develop a top-level lithography machine that can produce 1-nanometer chips.

Even the scientific researchers and even academicians accompanying him couldn't help but start talking in low voices at this time.

"Currently, overseas countries are in the process of developing 5-nanometer manufacturing processes. It is not easy for us to catch up with them, let alone reach the physical limits of silicon-based chips."

"In my opinion, it is probably more difficult to produce 1-nanometer silicon-based chips than to develop carbon-based chips."

"Although our current research results are still at a backward stage, they are accumulated by generations of scientific researchers. Only by standing on the shoulders of giants can we stand higher. How can we overthrow it?"

"For top-level chips with such specifications, the problem of photoresist will also be very difficult."

"It seems we need to have a good talk with the dean."

"Although Xu Lei is a genius, his personal power is always limited. Even without his help, I believe we can achieve new technological breakthroughs."

…

Xu Lei and Yang Senping listened to the discussions of many scientific researchers and academicians.

Because out of politeness, they only communicated in whispers and did not question him in person, Xu Lei didn't care.

Yang Senping, on the other hand, looked embarrassed and didn't know what to say.

When the whole atmosphere seemed a little strange, Xu Lei continued talking calmly after the silence returned.

"Theoretically, it is indeed difficult to produce a 1-nanometer chip in reality. However, with the help of the powerful ability of the intelligent assistant Xingtong, after conducting simulation verification on various materials, we successfully found a metal material that can break the restrictions and produce a 1-nanometer chip. .”

"By applying this material to the chip using advanced technology, top-level photolithography machines can be used to etch circuits."

Yang Senping knows very well what it means to break the physical limits, and judging from Xu Lei's past performance in breaking through overseas technology monopolies, he does not think that Xu Lei is making empty talk.

Coming here from Binjiang City without any hesitation, and speaking these words in front of so many scientific researchers and academicians, he must have absolute confidence.

If Yang Senping is still indecisive at this time, he will not be able to be the dean.

Almost as soon as Xu Lei finished speaking, he took over the conversation and said: "Since Mr. Xu is so sure, let's work hard. Regardless of whether the application can be approved or not, we must immediately start the production of top-level lithography machines. I will shoulder any responsibilities in research and development work.”

"Don't worry, Dean Yang, you will be grateful for today's decision."

After receiving Yang Senping's guarantee, Xu Lei suddenly felt impatient.

I want to get into research and development work as soon as possible.

After all, the exhibits he had unlocked before were all related to software technology, so he spent most of his time typing code.

It's relatively boring.

However, the development of top-level lithography machines belongs to the hardware aspect, and includes various aspects of knowledge such as mathematics, physics, optics, chemical materials, etc. For those who are keen on learning and seeking knowledge, it is not an exaggeration to call it a gluttonous feast.

But in order to make this top-level lithography machine available as soon as possible, he needs to stay at the Chinese Academy of Sciences for a while and work with those outstanding scientific researchers and academicians.

Therefore, the company's business needs to be arranged in advance.

…

That night.

In the hotel where Xu Lei and the others live.

"I'm safe here, and I'm afraid I won't be returning to the company in a short time. You two should go back to Binjiang City first. If you have any problems, just report to me online through Xingtong."

Compared with Binjiang City, the headquarters of the Chinese Academy of Sciences, which is responsible for various advanced technology research, undoubtedly has greater security.

In addition, Xu Lei will rarely handle the company's business personally, so there is no need for Chen Shihe and Cheng Fei to stay.

But faced with this decision, both of them shook their heads and chose to refuse.

"Mr. Xu, our duty is to protect your safety. No matter where you are, we will be there. We have no connection with the environment."

"Yes, Mr. Xu, it will be more convenient for you to handle things with us."

After listening to the two people's answers, Xu Lei slowly raised his eyes to meet those two pairs of firm eyes, and suddenly a wry smile appeared at the corner of his mouth.

In desperation, he had to agree.

"Okay then, you just stay here for now."

After settling the matter about Chen Shihe and Cheng Fei, Xu Lei returned to the bedroom and lay on the bed after taking a shower, closing his eyes slightly, and controlled his consciousness to enter the museum hall again.

Because he was woken up by Chen Shihe in the afternoon, he still had some technical knowledge that he had not thoroughly understood.

I will definitely continue to research now that I have time.

After all, he will soon become the general person in charge of the top lithography machine research and development project. Only by mastering all technologies can he better lead everyone to solve lithography machine problems.

Yang Senping's performance did not disappoint him. In just two days, the application report he submitted was approved, requiring the entire hospital to do its best to cooperate with Xu Lei in developing this top-level lithography machine that can break through the physical limits of silicon-based chips. machine.

As for why he was so decisive in this matter, in addition to Xu Lei's previous technical achievements, there was also Yu Hongliang's strong support.

Obviously, Xingtong has also achieved remarkable results after applying it to the military's technological research and development.

I recommend a new book by a big guy, a Naruto fanfic, which will be published in Sanjiang next week.
