Rekindle 2003

Chapter 729: Please die, sir!
Emperor Yun smiled and tapped the work permit with the finger holding the cigarette.

Cheng Jin was a little helpless.

Take a look!

Could it be that Qing Yun has a higher level than Xiao Ya in the work permit?

Then he will doubt whether this work permit is fake.

After all, colleges and universities are also institutions, and there are promotions in them. For example, he became the dean of a second-level college at a young age.

But there are age limits for promotion.

Otherwise, based on his "achievements", it would be no exaggeration to be elected as an academician right away, without having to wait until the age of 40.

Seeing the hesitation on his face, Emperor Yun was speechless and said impatiently,

"Open it and take a look! It won't cost you anything. Besides, you are a dying person. Do I have to lie to you?"

Cheng Jin rolled his eyes again when he heard this.

Although his contact with Qing Yun was very short.

But, actually, who the hell doesn’t understand whom?

A gentleman is a metaphor for righteousness.

And he and Qing Yun are both Yu Yuli's villains, and he can't mistake this.

It's just that the beatings from society made it clear to Cheng Jin that this classification is in the middle, not either/or.

What Qing Yuntu wants is to strive for the great interests of the country or nation on the basis of preserving his own small profits.

Black to the extreme is white?
Cheng Jin shook his head and opened his work permit as Qing Yun wished.

As expected, he froze.

"This this……"

Emperor Yun, who had realized his bad taste, smiled and reminded him, "The stamp is here, please look at the date again."

Cheng Jin first put his work permit on his lap, wiped his hands vigorously on his trouser legs, and then held his work permit in his hands and looked at it carefully.

"Year 1999?"

Looking at the date above, Cheng Jin's lips trembled.

Emperor Yun glanced at him and said calmly, "This date can explain your behavior of stealing the drawings from the motorcycle mule as... you know."

After that, he sighed, looked at Cheng Jin and said sincerely, "Teacher, I have done everything I can do for you."

Cheng Jin closed his work badge, pressed his hands on his chest, closed his eyes, but tears flowed from the corners of his eyes, and murmured, "You've been fined long ago."

Regardless of whether Cheng Jin could see it or not, Qing Yun shook his head at him, "No, to be honest, it was an impromptu idea two days ago."

He patted the center console in front of him and continued, "In my original plan, now was the time to send you on your way. But..."

Looking at Cheng Jin who opened his eyes, Emperor Yun smiled, "After all, it's a teacher-student affair, and I'm worried that your ghost will linger in the future, keeping me awake at night.

And, honestly, it would be in my best interests to have you become a martyr. "

Cheng Jin wiped his face and smiled, "Thank you!"

After taking out a tissue to blow his nose, he sniffed, but a determined look appeared on his face, "What do you need me to do?"

Qing Yun handed over a photo, "The day after tomorrow, there is a semiconductor industry summit in the Netherlands, and I got an invitation letter in the name of Yanhuang Group.

When you are transferring flights at Pearl Harbor, you will meet him and kill him. "

Cheng Jin frowned when he heard this, "Why is it him?"

He had many doubts, such as how to kill, what should he do after killing, and commit suicide on the spot?

But compared to the people in the photos, these are minor details.

To him, this was incredible.

Emperor Yun glanced at him, "Do you know him?"

Cheng Jin rolled his eyes and said, "Nonsense! I'm in this business too! Although I'm a bit inexperienced, I do scientific research after all, and I still know what new trends are in the industry."

He clicked on the photo with his finger, "Lin Benjian, a senior engineer at EMC, proposed immersion lithography technology last year as the current 193nm lithography light source has been stagnant for more than years, which is a new development direction."

Having said this, he shook his head, "However, his theory is not accepted by the current market. When it was proposed last year, there was no market to pay for it.

现在的路径一共四大阵营，尼康占主导的157nm激光、因特尔BMD摩托骡拉联合的13.5nmEUVLLC、NEC托西巴NTT和IBM联合的1nm接近式X光、朗讯贝尔实验室高的0.004nmEPL和0.00005nmIPL。

The latter two are considered the romantic camp. They do purely theoretical research and have never thought about industrialization.

EUV is too advanced and cannot be realized in the short term.

Personally, I am more optimistic about Nikon’s dry 157nm technology path. "

Qing Yun smiled. He was too lazy to talk to Cheng Jin about the scientific heroic view of history, and he was not interested in talking to him about technical paths. He said,
"ASML in the Netherlands is working with Lin Benjian to tackle immersion lithography technology."

Cheng Jin shook his head when he heard this, "It's useless. The immersion type can indeed skip 157nm through water droplet refraction and go directly to the 134nm wavelength. Then it will be stuck by the highest production resolution of 65nm. What will happen then?
Xiaoqing, photolithography must follow the Rayleigh formula. λ is the wavelength of the light source, NA is the numerical aperture, and k is the photolithography process coefficient. The three together determine the resolution CD of the projection lithography machine.

The resolution of the lithography machine is directly proportional to the wavelength of the light source. If you want to create smaller sizes, you need to shorten the wavelength of the light source. This is also the core of the evolution of the lithography machine generations.

Therefore, no matter how you refract, you still have to solve the problem through the wavelength of the light source. "

Qing Yun, who was familiar with the funeral, knew very well that what Cheng Jin said was right.

The light sources of immersion type, immersion type, and immersion type are all 193nm lasers, followed by another parameter based on Rayleigh's formula: aperture to achieve improved accuracy.

After that, there is the secondary exposure technology, which is also based on the 193nm light source.

In the end, after DUV, ASML still took the EUV path with a wavelength of 13.5nm.

But that was more than ten years later.

At that time, ASML was already a dominant player, and its leading advantage allowed it to switch tracks at will. However, this was not the case in the lithography machine market at this time.

This is still a period of melee among the heroes. Whoever breaks through first will be the winner.

The battle between ASML and Nikon and Canon's lithography machines is actually a story of a weak man desperate to break out with the gambling mentality of "the one who is barefoot is not afraid of wearing shoes".

ASML's success lies not in how advanced Lin Benjian's technology is, but in Lin Benjian's highly business-friendly process plan.

Half a year after ASML launched immersion 193nm products, Nikon also announced the completion of its 157nm products and EPL product prototypes.

However, Lin Benjian's immersion model is a small improvement with big effects, and the product maturity is very high, so almost no one orders Nikon's new products.

This is the characteristic of semiconductor products, and the market has the final say.

Win the market and win the opportunity to iterate.

He thought for a while and said patiently, "Teacher, you know, I am a businessman. So I am used to looking at problems from a business perspective."

Picking up the mineral water and taking a sip, Qing Yun continued, "Tell me, from the perspective of investment...or improvement of the current process, is it easier to go to 157nm or immersed 193nm?"

Cheng Jin looked at him blankly, shook his head and said he didn't know, "But the technical path is there, and scientific research must overcome difficulties."

Seeing this, Qing Yun could only shrug helplessly, "Scientific research is a matter of scientific research, but as an entrepreneur, let me tell you, I will definitely choose the easy one.

If there is money and market, I can continue to pay for scientific research. Without money, I can't do anything. "

Cheng Jin hissed when he heard this, and he seemed to understand a little bit.

Qing Yun smiled, "We want to catch up with others, what is the best way?"

"Overtaking on a curve?"

Cheng Jin sneered. He said that this slogan has been shouted for 20 years. At least in the semiconductor industry, the further it surpasses, the farther away it is from the world's top level.

Qing Yun rolled his eyes and said, "It's to make the enemy fall into the quagmire."

He spread his hands and said, "The world has been stuck on the 193nm lithography process for more than 20 years. We have just started. Huadian Institute 45 only started research last year.

In other words, from the perspective of generational gap, there is not much difference between us and the world at this time, right? "

Cheng Jin felt his teeth hurt a little.

What's more, from this perspective, there is really no difference.

But what kind of photolithography machine is not just about the light source?

Qing Yun smiled when he saw this, "I know it's still far behind, but we can see it now, right? But if they walk slower, won't the gap between us get smaller?

As a businessman, 197nm immersion can immediately achieve 65nm production, directly bringing the current 130nm process to the half cycle.

As for dry 157nm, they still need to start from the current 130nm and continue for several generations to reach the 65nm level.

You said, as a businessman, how do I choose? "

At this point he paused, "The reason Nikon insists on 157nm is because they have invested too much in it and they can't look back.

And ASML... is half-dead now, they are gambling with their lives. but……"

Qing Yun looked at Cheng Jin steadily, "Teacher, what if their bet succeeds?"

Cheng Jin was stunned when he heard this. He is not a pure researcher.

He is just a scientific researcher chasing ducks to the shelves.

Moreover, his native family is actually also in business.

At this time, looking at the problem from the perspective of a scientific researcher, he understood.

Qing Yun said calmly, "If he dies, I dare not say that ASML will never be able to develop immersion. In fact, ASML has been cooperating with him for more than half a year.

But we will gain precious time to catch up or even catch up.

You also know that the immersion type has a very low degree of difficulty compared to the dry type. Lin Benjian came up with an incredible idea, not a revolution in technology. We are jumping on the basis of the existing third generation. It is not impossible. achieved. "

We reached 07nm in 90, but the optical system was too stretched. When others saw that you had made it, they simply refused to sell accessories, which made it impossible for us to mass-produce. It was not solved until ten years later.

And it turns out that drying is, in a sense, a detour.

Because dry lithography machines rely on equipment and instruments, especially optical devices, which are too high-end, the development of the domestic industrial chain is uneven and cannot form effective support and cooperation.

But the immersion type is different. The only thing missing is the 193nm light source and 193nm photoresist. The rest, even the blank area, is very simple.

The light source and photoresist are not as difficult as Gang Jing thought.

After all, when it comes to playing with lasers, China, to put it politely, is at the level of its ancestors, but to put it bluntly, everyone here in the global village is scum.

The reason why it couldn't come out before is that it's better to buy it than to make it. Just like chips, there is no market iteration.

And we were in the process of integrating into the global industrial chain at that time. To be honest, don’t think about it in hindsight. At the beginning, almost no one would have thought that there would be any bottlenecks.

The second is the utilitarian nature of scientific research. There has been no domestic manufacturer of lithography machines for a long time, so who will research the light source? What to do with research?
Concentrating our efforts on doing big things means grasping the big and letting go of the small.

In fact, it only took 11 months from the beginning of the war, when Keyi Hongyuan was ordered to take over the task, to the successful shipment of the first high-energy excimer laser.

And photoresist is even worse.

This is an extremely small market.

The global semiconductor photoresist market size in 2021 will total US$91.8 billion.

Moreover, this is the figure when the domestic culprit was taken advantage of and purchased at almost several times the price.

The overall market size of photoresist has increased from US$14 billion in 20 to US$21 billion in 91.8. Domestic manufacturers have made huge contributions.

Before sending samples, photoresist manufacturers need to purchase a photolithography machine for internal formula testing and adjust the formula based on the verification results. However, the photolithography machine equipment is expensive and the one-time investment is large. The market ceiling of the photoresist itself is about one hundred. billion, which is why the domestic photoresist industry developed slowly in the past.

But this itself is in the field of fine chemicals, which is actually another strength of China, and can be achieved with a little tinkering.

2020年半导体光刻胶国产化率0%，2021年1%，2022年7%，2023年13%。

It seems that the value is very low, but there is a very important factor here, the introduction cycle.

Due to the complexity and variety of photolithography in the chip manufacturing process, different photolithography processes and different manufacturers of the same photolithography process have different requirements for photoresist. Photoresist manufacturers need to adjust the photoresist formula to meet the differentiation. need.

After the photoresist reaches the technical specifications required by downstream customers, it still needs to pass 2 to 3 years of verification testing. Therefore, the photoresist has high customer barriers and the introduction time is too long.

But, it’s not nothing.

When Qing Yun searched for things according to the picture, he could even directly name which unit would do what.

But the premise is that he has the right to speak in this industry.

If you have money and power, you have the right to speak.

The same is true in the scientific research community.

Cheng Jin understood, although he still couldn't completely agree with Qing Yun's views, but...

What does this have to do with him?

To him, it was a deal.

Thinking of this, Cheng Jin turned to look at Qing Yun, "What are the specific details? I won't stab him with a knife, right? And..."

Cheng Jin smiled and said, "Use me as the 'Father of Chinese Chips'. You must be trying to blame others, right? So it's not that rough."

Qing Yun gave him a thumbs up, and then said slowly, "Use a poisonous needle."

Cheng Jin understood instantly after hearing this, "The kind of hoopoe bird? One for him and one for me?"

At the beginning of the century, there was a lot of fuss about the assassination of Khalid with a poisonous needle by the hoopoe Satsuma.

After the matter was made public, people learned that this thing had been a feeding tool for agents as early as the Cold War.

Coupled with the Pearl Harbor mentioned by Qing Yun just now, Cheng Jin understood the plan instantly.

Pearl Harbor is just right.

It's a special location, but it's within the country, so it's easy to operate.

When it comes to Europa, it’s hard to say.

Qing Yun nodded, "There are professionals who will teach you exactly how to do it."

After that, he took out the scissors and cut off the plastic tie on Cheng Jin's leg.

After Cheng Jin moved his body, he looked at the tie in Qing Yun's hand and smiled playfully, "Aren't you afraid that I will open the door and run away now? Or that I will drive the car and die with you now?"

Qing Yun shrugged, "Teacher, I advise you not to be stupid."

After that, he pointed at the work permit that Cheng Jin had been holding in his hand, "Think more about my junior brother."

Cheng Jin patted his work permit in his hand and said, "Okay, this trip to the human world is worth it."

Under normal circumstances, if he didn't cheat, he would never be able to give his son such treatment in his life.

As for the fraud, he actually knew very well that it would be exposed sooner or later, but he was just unwilling to face the reality.

Because the funds are simply not enough to support his lies.

Seeing that he was so cooperative, Qing Yun was completely relieved. She smoked a cigarette, lit it for him while protecting the fire, and then said sincerely,

"Teacher...what else do you wish for? I will do whatever I can do."

Cheng Jin gave him a funny look, "Are you worried that you won't be able to sleep at night in the future?"

Looking at the cheap disciple's embarrassed appearance, he laughed, "Don't worry, I won't look for you."

After that, he thought for a while, "I want to see my parents, wife and children one last time."

Qing Yun pondered for a moment after hearing this, and then said awkwardly, "To be honest, I can only let you meet me from a distance."

Cheng Jin didn't look depressed either.

He also knew very well that this was indeed embarrassing.

Qing Yun would have to take risks if he was willing to meet him from a distance.

He shrugged, "Forget it."

As he spoke, Cheng Jin handed the work permit in his hand back to Qing Yun, "Please keep it for me."

After saying that, he smiled freely and said, "I definitely won't let me carry this thing with me.

And only you know whether it is true or not.

If it is true, you also know how to use it to maximize my interests.

So, over to you. "

Qing Yun was not polite, took it and put it back in his pocket, then patted it and said with a smile,

"Don't worry, I don't want to have nightmares."

Cheng Jin threw the cigarette butt out of the window, "What should we do now?"

Qing Yun looked at his watch, "Now you need to change cars and follow them to the airport to fly to Pearl Harbor overnight."

After saying that, he stretched his hand out of the window and made a gesture.

After a while, several young men appeared on the side of Cheng Jin's car door.

Cheng Jin didn't talk nonsense, got out of the car and followed the others.

Qing Yun, who was sitting in the car, was silent for a few seconds, then chased out of the car, shouted at Cheng Jin's back, and bowed deeply.

"Disciple Qingyun, I would like to send you my teacher!"

After all, Cheng Jin was unscathed in his previous life.

Cheng Jin didn't look back, raised his hand and waved, and went straight into the car without saying anything.

The night fell, and the stars dotted the sky, as if they were bidding farewell to Cheng Jin who was about to leave.

The red flashing taillights gradually blurred in the night, and finally disappeared at the end of the darkness.
