From Almighty Scholar to Chief Scientist

Chapter 240
The old man said: "Dear scientists, good morning, everyone's time is precious, so I will make a long story short and briefly talk about the purpose of this meeting."

"In recent years, we have been developing towards the semiconductor industry chain, and today we have achieved some fruitful results. Some time ago, under the leadership of Mr. Lin Xiao, we have achieved breakthroughs in multiple technologies, especially in silicon crystals. The round production technology has made a major breakthrough and reached a world-class level.”

Speaking of this, he nodded to Lin Xiao, and then continued: "The research of semiconductor technology is the top priority, and we need to achieve more innovations in this technology in the future."

"Now, everyone can talk about their own views, talk about the new breakthroughs in the technologies of all parties, and discuss which direction we should develop next."

After the old man finished speaking, the people present began to discuss.

After a while, Huaxin International's experts raised their hands and said: "Recently, we have achieved a key breakthrough in the chip production process, and we are one step closer to the 12nm process. We need more research and development in this regard. put in."

"I think we still need to increase investment in the production process. After all, it is still far away to build our own lithography machine. It is better to figure out how to study the DUV lithography machine to the limit first."

As soon as this was said, others were unwilling.

For example, Dianke Group, Changchun Institute of Optics and Mechanics, and Modu Microelectronics, all three have received the task of developing lithography machines. Huaxin International advocates vigorously developing production technology, and of course they are unwilling.

So the three companies immediately expressed their opposition.

"Don't do it if you can't do it? Don't you look at how much we have lost because we didn't do these things now."

"You talk about the production process, but you haven't seen how much you have done? Let alone 14nm, TSMC has 12nm and 10nm processes. I don't ask you to keep up with 7nm, but at least you won't be so many generations behind, right?"

……

Both sides said very impolitely, and naturally, they started arguing directly.

Of course, after all, it was such an occasion, and when they quarreled, they all blamed each other for problems in technological development.

But when they were arguing, someone said: "I think, should we work on the materials?"

Many of the people present are still producing materials. When they heard someone mention this, they immediately echoed.

"Yes, we should also focus on the development of materials!"

There was another voice in the meeting room again.

This is the semiconductor industry chain, each link is closely connected, and there are relatively large technical barriers between each link.

While these people were arguing, someone suddenly clapped their hands, and everyone saw that it was Director Ma.

For the director of the Science and Technology Bureau, everyone present still maintained a respectful attitude, so they all fell silent, waiting for him to speak.

Ma Gaoliang just smiled, and then said: "What everyone said is very reasonable, but you also know that we want to keep up with foreign countries, and there is still a long way to go in every link. Now we are only in the production of silicon wafers. This comes to world-class status.”

"So I thought, should we listen to Professor Lin's opinion first?"

Hearing this, the experts present all fell silent.

In any case, based on Lin Xiao's recent achievements alone, they deserve to be taken seriously.

So everyone turned their eyes to Lin Xiao who was sitting in front.

And Lin Xiao was a little surprised that it was his turn to speak suddenly, but he was already prepared to share his thoughts, so he was not in a hurry.

Sitting up, he first smiled at the old man on the right, then turned his head to look at the people present, and then said: "My opinion is that both hands must be grasped, and both hands must be hard."

"Of course, this sentence applies to the entire industrial chain, that is, the entire industrial chain, and we must firmly grasp it."

Everyone present was stunned for a moment.
What does Lin Xiao mean?

He thinks all directions must be developed?

All the people present couldn't help shaking their heads. They thought that Lin Xiao could come up with something eye-catching, but now that he said it, it was obvious to everyone that he didn't want to offend anyone and kept a moderate attitude.

However, is Lin Xiao really planning this?
After saying this, he stood up.

"The semiconductor industry is a complete industrial chain, and every part of the industrial chain plays a very important role. Since we have our special system, we can form a game of chess to carry out. Then, I think we should form a semiconductor industry. The alliance will centralize and deploy resources from all parties to better develop our entire industry."

"Now, our silicon wafer production has achieved a breakthrough. At the same time, because of the appearance of the eight-point structure of the encoder, our precision processing technology has also achieved a breakthrough, and the rest is to continue to dig deeper. "

"Here, I will first give a brief account of how to achieve breakthroughs in the production technology of optical lenses used in lithography machines."

Speaking of this, Lin Xiao smiled slightly at Luo Gangxian, but Luo Gangxian was taken aback. Lin Xiao wanted to talk about their optical lenses?
Lin Xiao said: "How to make optical lenses more precise is nothing more than getting rid of those raised particles on the surface of the lens."

"We can use laser interferometers to find these raised particles, and then for the amount of raised particles, we can bombard these raised particles with an ion beam, and then 'knock' our lens flat. .”

"This way, our lenses can become incredibly flat."

Hearing Lin Xiao's thoughts, Luo Gangxian couldn't help but said: "This... this shouldn't be possible, right? We can only make statistics on the surface roughness data obtained by the laser interferometer, but we can't specifically judge how to do it. Use ion beams to bombard! Moreover, the radius of silicon atoms has reached more than 100 picometers, and the diameter is equal to more than 200 picometers. What we need is a level below 100 picometers. If it is ion bombardment, the surface atoms are directly given to If it is bombarded, what is left may be a pit of more than 100 picometers, which still cannot meet the requirements of the lithography machine lens!"

What Lin Xiao said is indeed a very good method, but it is theoretically speaking. As a professional, he does not believe that this can be done at all.

Lin Xiao just smiled and said, "I didn't say to blast away these protruding particles, Academician Luo."

"I said 'knock flat'!"

"We only need to calculate the bombardment angle and control the horizontal and vertical component forces, and we can completely flatten its surface."

"Moreover, what we call the atomic radius is actually just the radius of the atomic orbit. In terms of the range of force, they are not a ball. When bombarded with ion beams, it is just the electromagnetic force between them."

"The previous ion polishing technology used argon plasma. When bombarding, we considered the amount of charge, so it can be realized."

Hearing this, Luo Gangxian suddenly felt incredible. What he said seemed to be really feasible?
But after thinking for a moment, he shook his head slightly and said, "This can't be done, it can't be done mathematically! How do you calculate the bombardment angle?"

Lin Xiao smiled: "It's just a math problem, and it's the math problem that I'm least afraid of."

"This……"

Luo Gangxian's words froze.

Just a math problem?
That's it?

He didn't know what to say, but looking at Lin Xiao's appearance, he couldn't find a reason to continue questioning.

It seems that it is really possible to do this?

If they could calculate the beam's impact angle, it would indeed seem entirely possible to knock those particles in?
In fact, this is similar to a kind of ion polishing technology, but compared with those more common ion polishing technologies, their technology requires a little higher precision.

And to solve this problem, the most important thing is not the math problem?
Thinking of this, he looked at Lin Xiao who had already walked to the other side of the oval table, stood up and said, "Professor Lin, you convinced me, let's cooperate."

Lin Xiao smiled and said, "Of course, it's just..."

He glanced at everyone present and said: "Everyone, I just said that we are going to form an alliance, so I want to work with all of you."

"As for any technical problems you encounter, you can come to me for cooperative research."

Hearing this, everyone present widened.

With Lin Xiao's words, is he planning to bring together the organizations and enterprises represented by all of them?
He even said that if you encounter technical problems, you can go to him for cooperation?

Although Lin Xiao has solved the CMP material technology, as well as the silicon wafer purification technology, and even achieved a major breakthrough in the accuracy of the encoder, he can be called an all-around talent.

But with so many industries in which they are present, how can Lin Xiao be omnipotent?
Someone immediately objected: "Professor Lin, your proposal is very good, but do you know how to solve the problem of extreme ultraviolet light source? This is the first question we want to ask you."

Lin Xiao smiled: "The extreme ultraviolet light source is nothing more than the excimer laser irradiating on the tin target, de-exciting to generate extreme ultraviolet light, and what we need to do is to increase its power."

"For this point, we only need to control the power of the tin target and the excimer laser, so that the tin target can receive a greater irradiation rate of the excimer laser, and a stronger de-excitation effect can be achieved."

"As for how to achieve a higher irradiation rate for tin targets, this requires mathematical calculation and experimental verification. Mathematical problems are also not a problem for me, so after you cooperate with me, we also have the opportunity to achieve breakthroughs."

"In addition, there is our collection efficiency of EUV light. In this regard, as long as the more precise processing of the lens I just mentioned can be realized, our collection efficiency can be increased again, and then the power can be increased."

Hearing Lin Xiao's answer, the objector was speechless again, because he found that he was actually moved by Lin Xiao's words.

If they can really cooperate with Lin Xiao, can their problems really be solved?

At this time, someone asked again: "Professor Lin, what about the optical system?"

Lin Xiao laughed again: "The optical path system, first of all, needs a breakthrough in the field of precision control, and I believe that now we have such an opportunity."

"The next step is still a math problem. Believe me, as long as it involves math problems, it's not a problem."

None of the people present knew what to say.

math problem?

Apart from material issues and precision machining issues, isn't the rest of their problems just math problems?

Many people don't know how to ask again.

Of course, those who study materials have something to say: "What about our photoresist?"

Lin Xiao said: "It took me two months to solve the CMP polishing material. Although I can't guarantee the other materials, maybe I can solve it if I'm lucky."

"Ah this..."

"Professor Lin, and us..."

……

Lin Xiao answered them one by one, and at the same time persuaded them one by one.

It's like fighting a group of Confucians with words.

He has long had the idea of ​​forming such an alliance.

But now, his achievements in semiconductors gave him such an honor to mention this matter.

Today's meeting just gave him the opportunity to put forward this idea.

Just like that, all the people present had excited expressions on their faces when he spoke.

He seemed to be convinced.

Seeing this scene, Lin Xiaosong said earnestly, "I'm not trying to grab everyone's things, but I just think it's necessary for us to establish such an alliance to better mobilize our resources."

"Friends, there is still a gap between us and foreign countries, and cooperation is more appropriate."

"Here, I don't want to argue with everyone."

"At the same time, please believe me, I also have this confidence."

There was a moment of silence in the conference room.

Academician Luo Gangxian, director of the Institute of Optoelectronics, said: "I agree."

With someone at the beginning, other people who were still vacillating also said, "We also agree."

"agree."

This matter has no impact on their interests, it is just troublesome, and I don't think it will be meaningful to them after joining.

But now, Lin Xiao has convinced them.

Seeing that these people actually agreed, Ma Gaoliang couldn't help but look at Lin Xiao with admiration in his eyes.

I am afraid that only Lin Xiao can convince so many people.

And the old man who had not spoken all this time looked at Lin Xiao with a lot of appreciation.

Then, he said: "Very well, I am very happy that everyone can cooperate. Then, as a witness, I will name your alliance."

Hearing what the old man said, Lin Xiao smiled and said, "Of course it's the best."

The old man said with a smile: "Then call Huaxin League, keep it simple and direct."

"In addition, Professor Lin, if you need anything later, just contact Gao Liang, and I will ask him to fully cooperate with you."

"it is good!"

Lin Xiao nodded heavily.
