Chapter 91 Impossible? 【Ask for a recommended monthly ticket】

Yang Senping's research on the domestic lithography machine has developed from the initial millimeter process to the micron, and now to the nanoscale.

But it has always been left behind by overseas technology.

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

It is a far cry from overseas 5nm chips.

After all, every time the manufacturing specifications of the chip are increased by a small level, the difficulty of research and development will increase several times. If the technology is still overcome in the original way, I am afraid that when domestic lithography machines can produce 14nm or 7nm chips, they will have already achieved 3nm. Craft up.

will still lag behind.

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

Start directly at 1nm, the physical limit of silicon-based chips.

Such domestic top-level lithography machine technology will gain the dominance of the global semiconductor market, and there is no need to worry about being overtaken for a long time in the future.

Because Xu Lei has studied the technical knowledge involved in the exhibits of extreme ultraviolet lithography machines in the museum, and in order to produce silicon-based chips with the physical limit of 1 nanometer chips, a relatively special metal is required.

And it just so happens that this metal has the most domestic reserves.

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

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

Although the performance of carbon-based chips with the same specifications is much better than that of silicon-based chips, it still requires a lithography machine for production, coupled with the price of materials and the fact that it is still in the laboratory stage for the time being, whether large-scale mass production can be achieved is completely a question. unknown.

But Xu Lei also understood that it would not be so easy to convince Yang Senping if he didn't come up with some real materials.

So facing Yang Senping's inquiry, he immediately explained: "The technology you are currently researching is too backward. Even if there is a new breakthrough, it is at most just catching up with Shanghai's overseas companies."

"In this level of technical parity, they will still have an inherent advantage."

"It's not good for our development in the semiconductor industry."

"So since we want to do it, let's go straight to the stomach and reach the physical limit of silicon-based chips."

"Outdated technology is destined to be abandoned by the times. Dean Yang doesn't need to be distressed at this time. I believe you will be happy with today's choice soon."

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

At the same time, the brain is racing too fast.

Physical limit?

And why did Xu Lei suddenly become so confident?

Could it be...

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

In addition, Xu Lei rushed here from Binjiang City so happily this time, perhaps he has already conquered the manufacturing technology of the top lithography machine.

The original intention of this trip is to cooperate with their Chinese Academy of Sciences to manufacture lithography machines.

"He didn't directly agree because he was worried that I would not give up the current research results and wanted to test my cooperation sincerity."

"Yes."

"Definitely."

As Yang Senping's thoughts stopped here, he suddenly felt enlightened.

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

If Xu Lei really mastered the manufacturing technology of the top-level lithography machine, let alone abandoning the research results at this stage, there is no problem in pushing all of them to start over.

Thinking through the key points, Yang Senping finally showed his courage to be the dean.

Make a decision on the spot.

"Mr. Xu."

"In any case, please believe in our determination to develop domestic lithography machines."

"I will write a detailed report right away and apply to the higher authorities for the establishment of a special scientific research group to develop a top-level lithography machine for 3nm chips."

"And you will be in charge."

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

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

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

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

"No?" Yang Senping was stunned.

According to Xu Lei's physical limit, the industry recognizes that it is a 3-nanometer chip, and Yang Senping doesn't think he has misunderstood it.

After all, due to material limitations, it is impossible to develop a theoretical 1-nanometer silicon-based chip.

But just when Yang Senping was about to ask Xu Lei in surprise, a familiar voice sounded in his ear.

"This time I want to develop a top-level lithography machine that can produce 1-nanometer chips."

"1 nanometer, this is simply impossible!"

Hearing that Xu Lei said something that he didn't dare to think about, Yang Senping subconsciously exclaimed that he couldn't believe that Xu Lei could develop a top-level lithography machine that can produce 1-nanometer chips.

Even the accompanying researchers and even the academicians couldn't help talking in a low voice at this time.

"Currently overseas is in the research and development of 5nm manufacturing process. It is not easy for us to catch up with them, let alone reach the physical limit of silicon-based chips."

"In my opinion, it may be 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 who have gone on and on. Only by stepping on the shoulders of giants can we stand taller. How can we overthrow it if we say overthrow it."

"For such a top-level chip, the problem of photoresist will be very difficult."

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

"Although Xu Lei is a genius, his personal strength 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 the scientific researchers and academicians.

Xu Lei didn't care because he was only limited to chatting and whispering out of politeness, and didn't question them face to face.

On the other hand, Yang Senping was full of embarrassment, not knowing what to say.

When the whole atmosphere seemed a little weird, Xu Lei continued to speak unhurriedly after the silence was restored again.

"Theoretically, it is indeed difficult to produce 1nm chips in reality, but with the help of the powerful ability of the intelligent assistant Xingtong, after simulating and verifying various materials, we have successfully found a metal material that can break the limit and produce 1nm chips .”

"Using this material on the chip through advanced technology, the circuit can be etched with a top-level photolithography machine."

Yang Senping is very clear about what it means to break the physical limit, and from Xu Lei's previous performance in breaking through overseas technology monopoly, he does not think that Xu Lei is talking empty words.

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's voice fell, he took over the conversation and said: "Since Mr. Xu is so sure, let's work hard, no matter whether the application can be passed or not, we must immediately start working on the top-level lithography machine." For the research and development work, I will bear all the responsibilities.”

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

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

I want to get into the development work as soon as possible.

After all, the previously unlocked exhibits were all related to software technology, which made him spend most of his time typing codes.

It's relatively boring.

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

It's just that in order to make this top-level lithography machine come out as soon as possible, he needs to stay in the Chinese Academy of Sciences for a period of time, eating and walking with those outstanding scientific researchers and academicians.

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

……

That night.

In the hotel where Xu Lei and the others lived.

"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 through Xingtong Online."

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

In addition, Xu Lei will basically not handle the company's business in person, so there is no need for Chen Shihe and Cheng Fei to stay.

But facing 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. It has nothing to do 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 gaze to meet those two pairs of determined gazes, and suddenly a wry smile appeared on the corner of his mouth.

In desperation, he had to agree.

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

After solving the matter about Chen Shihe and Cheng Fei, Xu Lei returned to the bedroom after taking a shower, lay down on the bed and closed his eyes slightly, controlling 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 didn't understand thoroughly.

Now I have time to definitely continue my research.

After all, he will soon become the general manager of the top lithography machine research and development project. Only by mastering all the technologies can he lead everyone to solve the problem of lithography machines.

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

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

Obviously, Xingtong has also achieved remarkable results after being applied to the military's technology research and development.

　I recommend a new book by a big guy, Hokage Tongrenwen, which will be on Sanjiang next week.
