From Almighty Scholar to Chief Scientist

Chapter 250 Turned out to be a string? !
Just when Wang Jun felt his eyes light up, Lin Xiao turned over the PPT again at this time, and a spectrogram appeared on it.

The colorful, red, orange, yellow, green, blue, blue, and purple spectrums of seven visible lights form a wave-like image, and this picture shows both particle nature and volatility, which means that human beings are in the same state. The time has observed the particle property and the wave property, and it is not like the double-slit interference experiment, only the particle property or the wave property can be observed.

Wang Jun glanced at it, and soon felt a sense of familiarity. He had also seen this picture completed by scientists at the Swiss Federal Institute of Technology in Lausanne before, so he immediately knew what it was.

But what can be seen through this image?
This picture is just to test the wave-particle duality, and it has nothing to do with the phenomenon of diffraction?

Just when he was puzzled, Lin Xiao turned his head to look at the people present, and said, "Everyone, you can now, this image allows us to observe the two properties of light wave and particle at the same time, and then...uh."

Turning around, he found that among the people present, very few people were listening to him, and most of the others had already lost their minds, or picked up their mobile phones to play.

"It seems that what I said is still too complicated."

He smiled, and of course he didn't care, at least, there were still a few people listening.

When the people present heard what he said, several of them said: "Professor Lin, it's our business if we don't understand what you said. We'll just listen to the result then."

"Okay, let's get on with it then."

Lin Xiao shook his head, and then continued: "As an electromagnetic wave, light has the characteristics of wave-particle duality. Although we are studying the properties of waves, we cannot avoid discussing particles."

"And through this diagram that can show both the nature of wave and particle at the same time, we can calculate how the particle behaves during the wave diffraction process! Only in this way can we better explore the mystery of diffraction."

Hearing Lin Xiao's words, Wang Jun's eyes suddenly burst into light again.

Correct!
In the process of exploring wave diffraction, if we can analyze the behavior of particles, maybe we can really let them conduct research?
But the problem still arises, how to understand the behavior of particles in the process of wave diffraction?
At this moment, Lin Xiao took out the chalk again and wrote down a few formulas on the blackboard behind.

【∫|ψrad(θ，φ，r)|r...】

【ψ(θ)=exp(-πWθ)...】

【…】

"First of all, we can use these formulas to describe the wave-particle nature on this spectrum. Then, we can continue to use these formulas to describe the diffraction and interference phenomena I showed before. Next, Next, we will divide them separately..."

"OK, now, we are deriving the remaining function. Well, what we get now is the performance announcement of the particle. Of course, this particle performance diagram is a special performance under these experiments, and As long as we achieve the transition from the special to the general—"

"Then, the diffraction of the wave will fully reveal the inner characteristics as if it has been dissected."

"At that time, when we understand the law and nature of diffraction, we can easily calculate what kind of crystal structure will help us control the diffraction of X-rays, and then synthesize this crystal, plus our existing polishing Technology, a crystal lens that can zoom in and out of X-rays, was born like this!"

"Next, we only need to directly control the graphics of the chip from the light source with the help of a computer, and then we can expose on the chip."

"Moreover, in the past LIGA process, our country already has SU-8 photoresist that can be used to expose X-rays, so we can say that as long as this crystal lens is built, we can start to manufacture Lithography machine! After it is built, we can start making chips!"

Lin Xiao's words immediately set off an uproar among the people present.

Even those who were still playing with their mobile phones were attracted by Lin Xiao's words.

Start building lithography machines directly?

This is what they have been looking forward to for a long time!
As a result, Lin Xiao now said that as long as this crystal lens is produced, they can directly build a photolithography machine?

Wang Jun's eyes were amazed, he believed what Lin Xiao said.

As a research institute that has accepted the task of manufacturing lithography machines, Changchun Institute of Optical Machinery certainly knows the three key technologies that Huaguo lithography machines currently lack. First, light source technology, but now if they replace X-ray light sources, these It will not be a problem. The second is the double workbench technology, but the double workbench is just a thing similar to a mechanical arm. As long as the precision is enough, it is enough. Now there are new servo motors, which were not sold abroad before. They already have the technical potential to manufacture their ultra-high-precision servo motors, and their Institute of Optics and Mechanics is also developing them, and they may be able to manufacture them next year.

And finally, the third is the lens technology, polishing technology, they already have, and now if it is really possible to create a lens that zooms in and out of X-rays, all three technologies have been completed, and there are no problems with other parts.

After all, Huaguo's basic strength is not false. Although the lithography machine, the largest semiconductor equipment, could not be produced in the past due to sanctions, but the etching machine, the second largest semiconductor equipment, Huaguo's technology was able to rank in the world. front row.

At that time, the three key technologies will be settled, and it will be completely possible to build a lithography machine!
Of course, the final key is that Lin Xiao can really explain the diffraction.

Although Lin Xiao's achievements are already very deep, but if he wants to break through the last few steps, it's not just a matter of saying that he can do it.

"Of course, it will take some time to solve this problem, but everyone, please believe that this is the only way we can break through foreign sanctions and achieve cornering overtaking."

"Okay, I've finished speaking, do you have any questions to ask?" Lin Xiao said.

Although most of the people below were still at a loss, they basically understood what Lin Xiao meant.

Solving a theoretical problem will give them a chance to overtake on a curve.

"Professor Lin, I just want to ask you a question. How long will it take you to solve this problem?"

Someone raised his hand and said.

Lin Xiao responded: "I can't give you the exact time, but even if it's a year or so, can't you afford to wait?"

When everyone thinks about it, it is true.

After so many years behind, how can I not afford to wait for a year and a half?

Then they think about the time it took Lin Xiao to solve those important problems before, maybe it won't take a year or a half?

"Professor Lin, I believe in you and hope you will succeed!"

The person who asked the question nodded and said no more.

Others also responded one after another, expressing their willingness to trust Lin Xiao.

But at this time, someone suddenly said: "Professor Lin, what about us? If you do this, is it equivalent to giving up our production of photomasks?"

Lin Xiao turned to look at this person.

It seems to be from a photomask company in China, Lin Xiao asked, "Are you from Yiqing Optoelectronics?"

"Yes, I am the general manager of Yiqing Optoelectronics, Cao Zhiyang." The man said: "Professor Lin, if you want to build an X-lithography machine, do you mean you have given up on our photomask manufacturer?"

Lin Xiao said: "Mr. Cao, I know what you mean, but if we can really build an X-lithography machine, we will indeed not need a photomask."

"How can this work!" Cao Zhiyang said: "Professor Lin, can't you think of a way to make the X-lithography machine need a photomask?"

Lin Xiao said helplessly: "Not using photomasks is our best solution in the face of foreign sanctions."

Others also started to speak for Lin Xiao, and Yu Jiancheng said: "Mr. Cao, isn't this difficult for you? Foreign countries have already imposed sanctions on your quartz materials, and you don't need to fight for these quartz material masks. Aren’t there still soda masks and other types of masks? You can’t just wait for Professor Lin to help you solve the quartz material, right?”

"Why not?" Cao Zhiyang glared at Yu Jiancheng: "Professor Lin Xiao in your factory helped you solve the problem of polishing materials and production technology. Why can't you help us?"

"Your company is not a state-owned enterprise!" Yu Jiancheng retorted.

"Does it mean that your state-owned enterprises are bullying our private enterprises?"

Yu Jiancheng couldn't answer this question, so he changed the subject and said, "I don't want to talk so much nonsense with you. We gave Professor Lin a production line worth several hundred million yuan for him to test, and then we spent money to buy new materials and technologies. Yes, you also give Professor Lin a few hundred million."

"Okay, you don't have to argue."

Lin Xiao interrupted their argument at this time and said: "Mr. Cao, we have to give up on the photomask, so I won't spend time solving the problem of the photomask."

When it is broken, it will be disrupted, and the thoughts of these companies will be cut off earlier.

Hearing what Lin Xiao said, Cao Zhiyang immediately showed annoyance on his face, and finally said angrily: "Then we, Yiqing Optoelectronics, will withdraw from Huaxin League."

Then, he left the office directly.

When everyone saw this scene, they didn't know what to say.

Huaxin League was established for the collective benefit. Now that the photomask has been abandoned, Cao Zhiyang is angry, which is not surprising.

However, for the collective benefit, the photomask must also be given up.

"Okay." Lin Xiao didn't care about this little episode, and continued: "That's all I want to talk about. Do you have any questions?"

No one raised their hands.

"Okay, that's it." Lin Xiao got up: "In the next period of time, I will devote myself to the research of this issue, and I hope that you can make important breakthroughs in your field."

"Dismiss!"

……

This meeting is over, although the future is still bleak, but at least X-ray engraving is not impossible, as long as Lin Xiao can create miracles again.

However, the withdrawal of Yiqing Optoelectronics still attracted people's attention.

At the beginning, Huaxin League was established with great vigor, but it turned out that some manufacturers have withdrawn in just a few months?

Moreover, it is also the leading enterprise of photomask in China, and there is still some gap between other leading enterprises of photomask and instrument optoelectronics.

Of course, it is not just the exit of Yiqing Optoelectronics. There is also a photomask company in China called Roadwell Optoelectronics. It is also a photomask company and has also withdrawn from Huaxin.

The withdrawal of these two enterprises has naturally aroused people's attention.

Cao Zhiyang, the general manager of Yiqing Optoelectronics, also accepted an interview with reporters afterwards.

In the interview, he bluntly stated: "Professor Lin Xiao wants to build an X-lithography machine, and our photomask is abandoned!"

This sentence immediately attracted everyone's attention.

Lin Xiao wants to do X-ray etching?

Photomask abandoned?

Both at home and abroad were shocked.

almost on.

[Professor Lin Xiao wants to build an X-lithography machine, what does it mean? 】

This question has been answered by many people.

"Foreign sanctions on us have increased. Professor Lin Xiao either did it as a last resort or out of anger, but I have to say that this is a challenging choice. 』

"X-lithography, the main problem to be solved is the problem of X-ray magnification and reduction. Only by solving this problem can the production efficiency of X-lithography machines be increased, and there will be a lot to do in the future, and because the energy of X-rays is strong enough, production Efficiency is estimated to be higher than that of EUV lithography machines.But the most critical problem is how to solve it. If Professor Lin can really solve it, it will definitely be regarded as the best scientific and technological breakthrough of the year. 』

"It turns out that there is still X-ray engraving. I have learned a lot. I can only hope that Professor Lin Xiao will succeed." 』

……

In fact, people in the industry in Huaguo can only hope that Lin Xiao can succeed. After all, since Lin Xiao returned to China, his contribution to semiconductors is obvious to all.

No one can deny his contribution to Huaguo Semiconductor.

In foreign countries, although they were shocked, they were more ridiculed.

Asmail, when Dawson Edinson heard the news, he directly stated publicly: "It is impossible for Lin Xiao to engage in X-lithography. X-ray machines are doomed to fail! Believe me, EUV light The engraving machine is the most suitable and economical solution finalized by our tens of thousands of first-class scientists and engineers over decades. X-ray engraving will be a joke in the end! Even Lin Xiao He is an outstanding, even a great scientist, but I believe that his wisdom alone cannot be compared with so many of our scientists!"

As the CEO of Asmail, Dawson Eddinson's words are not arrogant, but the words in it make people wonder how to refute.

Can Lin Xiao's wisdom be compared with tens of thousands of scientists?

Even in China, it inevitably aroused people's pessimism.

Could it be that the lithography machine can only take the EUV road?
……

About half a month later.

In Yanbei Garden, in the house belonging to Lin Xiao.

Compared with the reaction of the outside world, he cares more about his own research.

After calculating an unknown number of steps, he now made an astonishing discovery.

"It turned out to be a string?"

Lin Xiao looked at the result he got, with a shocked expression on his face.

It is strings that cause interference and diffraction between waves!
If it wasn't for his coincidence that he felt that M theory could be substituted into it, he wouldn't even be able to discover this at all.

At this time, a ridiculous thought came to him: "Could it be that I have indirectly proved the existence of strings?"

Professor Witten, do you have to come to thank him in person?
And all those scientists working on string theory?

"No, I have to try again!"
