From Almighty Scholar to Chief Scientist

Time passed by.

Recalling the proof of Hodge's conjecture, it seems that it is still in the previous chapters.

And Lin Xiao, as a prover, brought a Fields Medal winner. The time after the International Congress of Mathematicians was originally the period when the enthusiasm about him was the most vigorous.

However, people discovered that Lin Xiao had completely disappeared during this limelight.

If it's a different person, why don't we challenge it first?

Or live broadcast directly to bring the goods, come to Popanga's turn.

However, Lin Xiao never showed up, and the media could not be contacted. Apart from CCTV interviewing a wave of Lin Xiao, which added a famous scene to the Internet, other media who wanted to interview Lin Xiao had no choice but to give up.

As a result, the heat gradually subsided.

The day also came to August.

August [-]th.

……

In the dust-free workshop of the Dingguang Research Institute, there are five square instruments standing in the middle. Each instrument occupies an area of ​​about 5m*2m and a height of 4m. Compared with the EUV lithography machine of Asmer The area is smaller, but the height is higher, because compared with the complex optical path of the EUV lithography machine, the optical path of the X-ray light source is simpler. After all, X-rays cannot be refracted like EUV light, so the X-ray light source is also straightforward to install. In the past, it's just that since the X-ray source generator needs to be installed on it, the height is much higher.

At this time, a technician was operating the machine and installed the last piece of aluminum plate wrapped with lead plate.

So far, five X-lithography machines have all been born.

At the same time, each X-lithography machine has a casing with an "X" printed on it.

It is simple, but it makes people feel that it is hidden in it, which belongs to the most cutting-edge technology!

Chapter 300 Ren Dong, are you interested in reproducing the Kirin 9000 chip?

"What a work of art!"

After the last piece of aluminum plate was installed, a smile appeared on Lin Xiao's face, and he couldn't help but sigh with emotion.

Looking at these five huge machines, it can be said that he installed them hand in hand.

From the outside, the neat aluminum plate reflects the lights in the workshop, and the surface is extremely clean and tidy. As a mechanical instrument, it will probably not get dirty in its lifetime, unlike the computer case at home. It will collect dust and it will always be so shiny.

After all, the photolithography machine can print money even faster than the money printing machine. It can produce 10,000+ mobile phone Soc chips an hour, and the price of a Soc chip can be estimated to be about 500 yuan in the cost of the mobile phone. It is equivalent to printing nearly [-] million in an hour, which is not even possible for money printing machines.

Of course, things like printing money are just trivial things.

The most important thing is the economic circulation driven by a lithography machine, which is unmatched by a money printing machine. With a lithography machine as the core of the entire semiconductor industry chain, it will create wealth and jobs for the entire industry. Posts, which are also unmatched by money printing machines.

From upstream to midstream to downstream, a lithography machine can bring billions of dollars in economic circulation to the entire industry chain every year, and the semiconductor industry chain can create a market of more than 5000 billion dollars every year. Economic circulation can easily exceed trillions of dollars, and Huaguo's GDP in 2021 is only 17.7 dollars.

Another example is that the most profitable industries in the world are mobile phones, automobiles, and real estate, and the semiconductor industry is closely related to mobile phones and automobiles. Even smart homes in real estate can be related to semiconductors. No worse than these industries.

Therefore, occupying any key link in the semiconductor industry chain will bring huge profit space.

Why Japan can become the third economy in the world? From the perspective of their three major economic pillars, the first is the important market of automobiles, and then animation. Apart from these two, it is their semiconductor industry. If it is not for Shanghai In the Plaza Accord of the century, Japan, which originally occupied nearly 80.00% of the world semiconductor market, now has a GDP that is probably even higher.

In addition, whether it has independent chip production technology is very important for a country, especially a truly independent country like Huaguo.

As for another independent country, Russia, because the technology tree was wrong at the beginning, it did not make transistors, but made electron tubes. It has not made transistors until now, but obviously, the performance of electron tubes is obviously still incomparable with transistors, because electron tubes cannot Transistors are very small and mass-produced, so things like mobile phone chips, computer processors, etc., Russia also needs to rely on imports. When the neck is stuck, after all, there is no neck. Western companies are still willing to sell chips to Russia.

But for Huaguo, because it wants to develop semiconductors, and also wants to develop into a semiconductor powerhouse, it naturally encounters many difficulties and resistance.

However, these obstacles will become a thing of the past.

The five instruments in front of Lin Xiao will be the beginning of the rise of Huaguo Semiconductor.

In the workshop, not only Lin Xiao, but everyone else in the X-ray project also cast their eyes on the lithography machine in front of them, with excited smiles on their faces.

After so long, they finally built their own lithography machine!

And it is also the world's first lithography machine that uses X-rays as a light source and can be mass-produced!

How can this not get them excited?

Regardless of whether they succeed in the end, these five lithography machines costing as much as one billion yuan can already be called the sum of the wisdom of thousands of people in their X-ray project. Thousands of people, in fact, at least tens of thousands of Hua people directly or indirectly participated in their X-ray project.

Of course, everyone present knew that the one who paid the most was their chief designer, Lin Xiao.

The three core breakthrough technologies faced in the entire X-ray project process, including less than 100pm-RMS level polishing technology, as well as their double-table technology, and the most critical RDX pure silicon crystal, all took Lin Xiao's time. It was done, and what they solved was at most some common technical difficulties.

In addition to feeling a little embarrassed, they also know how cool it is to have a god-level teammate. They hardly do anything, and then no matter how difficult the problem is, it can be solved quickly.

Up to now, although the five lithography machines have not been turned on yet, they are considered to be the closest to success.

Yang Kaiping, the deputy chief designer standing next to Lin Xiao, also took a good look at the five big guys in front of him. After his heart was no longer surging, he looked at Lin Xiao and asked, "Chief Lin, what next? What shall we do?"

As he asked the question, the others also looked at Lin Xiao, waiting for his response as well.

Lin Xiao took a deep breath, and then said loudly: "Turn on!"

Hearing Lin Xiao's words, Yang Kaiping immediately turned his head to look at the group in charge of the power supply, and shouted: "Turn on!"

The next moment, the staff in charge of the power supply pulled down the five switches. Every day, the X-lithography machine is controlled by one switch. up.

Then, a person stood in front of each lithography machine console, and pressed the start button of the main computer, and then, the computer responsible for controlling the entire lithography machine started up.

The system uses the linux system, and there is nothing on the desktop, only one software.

The software is called [X-ray plan lithography machine control panel].

This software was created by the X-ray project software group. It can be said that they have been writing such a software since the X-ray project started.

This control panel is equivalent to the operating system of their X-lithography machine. The software is not complicated, but the code inside is quite complicated.

Whether the hardware of the lithography machine itself can meet the standard is the key to ensuring the performance of the lithography machine, and the software is related to whether the performance can be played normally. Of course, even if the software is made, it must be able to use the software , otherwise it is useless.

For example, Huaxin International and TSMC both bought Asmail's DUV lithography machine, but TSMC can use DUV lithography machine to produce 7nm chip technology, while Huaxin International can only achieve 14nm because it cannot Use software well.

Of course, before using the software, they must first ensure that the software in front of them can work normally.

First of all, click on the software, after a slow loading, finally, enter the first page of the software, the operation interface is all in Chinese, not including a single English letter.

At this time, Lin Xiao also walked to one of the lithography machine consoles, commanding: "First perform a system self-inspection on the entire lithography machine."

"Yes!"

The staff in charge of operating the lithography machine responded immediately, and then entered the control panel-system interface, and clicked on the system self-test.

Since it is a self-test, it is natural to check whether each internal component can operate normally. Of course, the most important thing is to check whether the precision of these mechanical operations can meet the standard, and whether the X light source can be normally excited and whether it can be normally activated. RDX pure silicon crystal mirror regular diffraction etc.

After a short while of loading, a progress bar appeared on the display, which means the self-test has started. However, the interior of the lithography machine is still quiet, unlike other machines, which make various noises when they are in operation.

Because if there is a sound, it means that there is vibration, and for the lithography machine, even a little vibration is fatal, so all the machinery in the lithography machine is basically frictionless, such as the double workbench. Use magnetic levitation to avoid vibration. Of course, the double workbench is the only one in the core machinery of the lithography machine that can move, and then the mechanical arm that controls the lens will also move, and other core components will basically not move. , the more variables there are, the more difficult it is to control.

In this way, time passed slowly, and everyone was silent, or showed nervous expressions, waiting for the result to appear, and some even began to pray.

Because this step is too critical, if the self-test fails, then they have to disassemble the entire machine again, and then check the part with the problem to find out what caused the substandard, and obviously, it will cost a lot of time.

And as long as the self-test passes, it means that their lithography machine is basically qualified!

It is possible to start producing chips!

Therefore, each of them is looking forward to, this time, they can directly succeed!

Just like that, about a few minutes later.

There was a crisp "ding" from the computer, and the four words [self-test passed] appeared in green on the screens of the five computers.

Seeing this, everyone present breathed a sigh of relief, and then they were all moved by it.

"Success!"

"We made it!"

Everyone present showed an extremely excited expression, what's more, their eye sockets were moist, and tears of happiness flowed out.

All the hard work for so long has not been in vain!

They really broke the Western blockade of lithography machines and created a top-level lithography machine made in their own country!

Everyone feels extremely excited at this moment.

I don't know how many of them hate the sanctions from foreign countries, but now, they can respond to those gringos with great pride, saying that they have also built top-notch lithography machines!

And Yang Kaiping, the deputy chief designer, was already in tears at this time.

As the designer of the domestic 600 series lithography machine, he is very aware of how difficult it is for Huaguo to develop this kind of thing, but now, they have succeeded!

Looking at the five lithography machines in front of me, all the precisions have reached the single-digit nanometer level, and even the light sources they use are 3.56nm-level X-rays, which are almost lower than EUV’s 13.5nm 10nm!

What is ASML's EUV lithography machine?

Still have to look at their X-ray machine!

Finally, he gently wiped away his wet tears, then turned his head to look at Lin Xiao, bowed at ninety degrees very seriously, and said, "Mr. Lin, thank you! Thank you for your hard work!"

Lin Xiao quickly went up to help him up, and said dumbfoundedly: "This is my responsibility as the chief designer, Chief Master Yang, you don't have to do this, not to mention, this is also accomplished by everyone's joint efforts."

Yang Kaiping shook his head and said, "Master Lin, don't be humble. Without you, we would not be able to succeed. We all know that."

Other people standing around also said: "Yes, Chief Master Lin, this is all thanks to you!"

Seeing so many people talking, Lin Xiao shook his head with a broken smile, and then said, "I won't argue with you, well, now we're all happy, and it's time to prepare for the next thing."

next thing?

Others' eyes lit up one after another, and they all asked, "Are you going to announce the news?"

Their X-ray project never hides news, and they announce it when there is a breakthrough. Now, their lithography machines are basically able to operate, and they can't wait for it.

However, to their surprise, Lin Xiao just smiled and said, "No hurry, didn't I say that I'm going to make our first chip on National Day?"

"We'll announce the news on that day!"

Everyone present couldn't help being stunned.

Build their first chip?

At this time, Lin Xiao asked, "Which one of you has Huawei Ren Zhengfei's phone number?"

All the people present looked at each other in blank dismay, wondering what Lin Xiao was going to do again.

And Yang Kaiping said: "I have."

As the leader of the domestic lithography machine, he also communicated with Ren Zhengfei, so he left the other party's mobile phone number.

Lin Xiao took out his mobile phone and said, "Give me his number."

Yang Kaiping nodded, then took out his mobile phone, found Ren Zhengfei's number, and reported the number to Lin Xiao.

Afterwards, Lin Xiao entered the number into his mobile phone and dialed the number.

After a while, the phone was connected.

An old man's voice came from the opposite side: "Who is it?"

"Dong Ren, I wonder if you are interested in reproducing the Kirin 9000 chip?"

Chapter 3 and One are ready to make chips!

Dongguan City, the Songshan Lake headquarters of Warwick Corporation.

Ren Zhengfei, who was sitting in his office, was taken aback for a moment when he was asked whether he was interested in rebuilding the Kirin 9000, and then he couldn't help laughing.

This call is most likely to come to them to invest, and his number is a private number. It is estimated that he got his phone number from one of his friends and then called.

In the past, he must have asked this person to call their Warwick rotating director directly, and he didn't have the heart to take care of this kind of thing.

But this time it was different, the other party actually opened his mouth and said that he would rebuild the Kirin 9000, which still made him a little interested.

Are all the people who attract investment so vigorous now?

So he smiled and said, "Of course I'm interested, but I just don't know how you plan to help us recreate the Kirin 9000 chip?"

A voice came from the other end of the phone: "Hehe, in order to prevent Director Ren from thinking I'm joking, let me introduce myself first. I'm Lin Xiao, the chief designer of the X-ray project."

Ren Zhengfei was taken aback for a moment, Lin Xiao?

X-ray project?

He immediately stood up from his seat and said, "Master Lin? Is it really you?"

Lin Xiao smiled and said: "Of course it's me. If you need me to prove my identity, then I can ask our chief teacher Yang Kaiping to call you. Chief teacher Yang is beside me now, and your phone number is also his. told me."

Ren Zhengfei thought for a moment, then said: "No need, I believe it."
