Emperor Yun smiled, and the finger holding the cigarette lit the work card.

Cheng Jin was a little helpless.

Look at the yarn!

Could it be that Qingyun's level in the work card is higher than Xiao Ya's?

Then he would have wondered if the work card was fake.

After all, colleges and universities are also systems, and there are promotions in it, such as him, who became the dean of a second-level college at a young age.

But there is also an age limit for promotion.

Otherwise, with his 'achievements', it is not an exaggeration to be rated as an academician immediately, and he does not have to wait for 40 years old.

Looking at the hesitation on his face, Emperor Yun was also speechless, and said impatiently,

"Open it and take a look! It doesn't cost you anything. Besides, you are a dying man, can I lie to you? ”

Cheng Jin was a roll of the eyes when he heard this.

Although he had only been in contact with Qingyun for a short time.

But, actually, who doesn't know anyone?

The gentleman is righteous.

And he and Qingyun are both villains of Yu Yuli, and he can't be wrong about this.

It's just that the beating of society makes Cheng Jin very clear that this classification is a middle ground, not an either/or.

Qing Yuntu's goal is to strive for the great interests of the country or the nation on the basis of preserving his own small interests.

Black to the extreme, white?

Cheng Jin shook his head, and opened his work card as Qingyun wished.

Unsurprisingly, he froze.

"This ...... This ......"

Emperor Yun, who had realized the bad taste, smiled and reminded him, "The steel seal is in Ha, look at the date again." ”

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

"In 1999?"

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

Emperor Yun glanced at him and said lightly, "This date can explain your behavior of stealing 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 card and pressed his hands on his chest, closed his eyes, but tears flowed out of the corners of his eyes, and muttered, "You have already calculated it." ”

Regardless of whether Cheng Jin saw it or not, Qingyun shook his head at him, "No, frankly speaking, it was improvised two days ago." ”

He patted the center console in front of him and continued, "Originally, in my plan, this is the time to send you on your way. It's just ......"

Looking at Cheng Jin, who opened his eyes, Emperor Yun smiled, "After all, there are teachers and students, I'm worried that your ghost will not go away in the future, so I won't be able to sleep at night."

And, honestly, you become a martyr, my interests can be maximized. ”

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

After blowing his nose with a tissue, he sniffed, but a resolute look appeared on his face, "What do you need me to do?" ”

Qingyun 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 transiting in Pearl Harbor, you will meet him and kill him. ”

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

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

But compared to the people in the photo, these are all minutiae.

In his opinion, it was incredible.

Emperor Yun glanced at him, "Acquaintance?" ”

Cheng Jin rolled his eyes back, "Nonsense! That's what I do! Although I do have a bit of water, I am a scientific researcher after all, and I still know what new trends are in the industry. ”

He pointed his finger at the photo, "Lin Benjian, senior engineer of Yi Semiconductor Manufacturing Co., Ltd., proposed immersion lithography technology last year under the stagnation of the current 193nm lithography light source for more than 20 years, which is a new way of development." ”

Speaking of 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.

At present, there are four major camps, the 157nm laser dominated by Nikon, the 13.5nm EUVLLC combined by Intel BMD Motorcycle Mule, the 1nm proximity X-ray jointly combined by NEC Tosiba NTT and IBM, and the 0.004nm EPL and 0.00005nm IPL by Lucent Bell Laboratories.

The latter two are considered romantic camps, purely theoretical research, and they have not thought about industrialization.

And EUV is too advanced to be achieved in the short term.

Personally, I'm still more bullish on Nikon's dry 157nm technology path. ”

Qingyun smiled, he was too lazy to talk to Cheng Jin about the historical concept of scientific heroes, and he was not interested in talking to him about the technical path, so 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 refraction through water droplets can indeed skip 157nm and directly achieve a wavelength of 134nm, and then it will be stuck by the highest production resolution of 65nm, what should I do then?"

Xiaoqing, lithography should follow the Rayleigh formula, λ is the wavelength of the light source, NA is the numerical aperture, and k is the lithography process coefficient, and the three together determine the resolution of the projection lithography machine CD.

The resolution of the lithography machine is directly proportional to the wavelength of the light source, and to create a smaller size, the wavelength of the light source needs to be shortened, which is also the core of the generational evolution of the lithography machine.

So, no matter how you refract, you ultimately have to solve the problem by the wavelength of the light source. ”

Qingyun, who is familiar with the aftermath, knows very well that what Cheng Jin said is right.

Immersion, immersion, and immersion are all 193nm lasers with light sources, followed by another parameter according to the Rayleigh formula: aperture, to achieve improved accuracy.

After that, there is the double exposure technology, which is also based on a 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 a decade later.

At that time, ASML was already dominant, and its leading edge could switch tracks at will, but this was not the case in the lithography machine market at this time.

At this time, it is still a period of melee between the heroes, and whoever breaks through first is the winner takes all.

The battle between ASML and Nikon Canon's lithography machine is actually a story of a weak man breaking through the Jedi in a desperate situation with the gamble mentality of 'barefoot and not afraid of shoes'.

ASML can win, not because Lin Benjian's technology is advanced, but because Lin Benjian has given a highly commercially friendly process plan.

Six months after ASML launched its immersion 193nm product, Nikon also announced the completion of its own 157nm product and EPL product prototypes.

However, Lin Benjian's immersion type belongs to small improvements and big effects, and the product maturity is very high, so almost no one orders Nikon's new products.

Semiconductor products are such characteristics, and the market has the final say.

Won the market and won the opportunity to iterate.

He thought about it, but said patiently, "Teacher, you know, I am a businessman. So I'm used to looking at things from a business perspective. ”

Picking up the mineral water and taking a sip, Qingyun continued, "You said, from the input...... Or from the perspective of improving the current process, is it easier to go to 157nm or to go to immersion 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 has to overcome difficulties." ”

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

If I have money and a market, I can continue to pay for scientific research, and I can't do anything without money. ”

Cheng Jin hissed when he heard this, he seemed to understand.

Qingyun laughed, "We want to chase others, what's the best way?" ”

"Overtaking in a corner?"

Cheng Jin sneered, he said that this slogan has been shouted for 20 years, at least in the semiconductor industry, the more surpassed, the farther away from the world's top level.

Qingyun rolled his eyes, "It's to let the enemy fall into the quagmire." ”

He spread his hands, "The 193nm lithography process has been stuck in the world for more than 20 years, and we have just started, and the 45th Institute of Huadian Branch only began to conduct research last year."

In other words, from the perspective of the generational gap, we are not much different from the international at this time, right? ”

Cheng Jin felt that his teeth hurt a little.

In particular, from this point of view, there is really no gap.

But isn't the special lithography machine just a matter of light source?

Qingyun smiled when he saw this, "I know it's still far away, but we can see it now, right?" But if they go a little slower, will we have a smaller gap?

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

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

You say, as a businessman, how do I choose? ”

Speaking of this, he paused, "Nikon is sticking to 157nm because they have invested too much in it, and they can't go back."

And ASML ...... Now half-dead, they're gambling with their lives. But ......"

Qingyun looked at Cheng Jin steadily, "Teacher, what if they succeed in their bet?" ”

Cheng Jin was stunned when he heard this.

He was not a pure scientist.

He's just a scientist who catches ducks on the shelves.

Moreover, his original family is actually also in business.

At this time, jumping out of the perspective of scientific researchers, he understood it.

Qingyun said lightly, "He died, I dare not say that ASML will never be able to develop the immersion type, in fact, ASML and he have been cooperating for more than half a year."

But we'll get precious time to catch up and even catch up.

As you know, the breakthrough of immersion type is very low compared to the breakthrough of dry type, and Lin Benjian has come up with an incredible ghost idea, rather than a revolution in technology, and we are jumping on the basis of the existing third generation, which is not unattainable. ”

In 07, we reached 90nm, but the optical system pulled the crotch, and others saw that you made it, and we couldn't mass produce it without selling accessories, and it wasn't solved until ten years later.

And it turns out that in a sense dry type is a detour.

Because the dry lithography machine relies on equipment and instruments, especially optical devices, is too high-end, the development of the domestic industrial chain is uneven, and it cannot form an effective support and cooperation.

But the immersion type is different, the only thing that is lacking is the 193nm light source and the 193nm photoresist, and the rest, even if it is a blank field, is very simple.

The light source and photoresist, these two, are not as difficult as Gong Jingjing thought.

After all, when it comes to playing lasers, Huaguo's polite statement is at the ancestral level, and you are not welcome, everyone in the global village is scum.

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

And at that time, we were in the process of integrating into the global industrial chain, and to be honest, don't let it be an afterthought, almost everyone would not have thought that there would be anything stuck.

The second is the utilitarian nature of scientific research, there has been no lithography machine in China for a long time, so who will study the light source? What do you do when you research it?

Concentrating on doing big things is itself a matter of grasping the big and letting go of the small.

In fact, it took only 11 months from the start of the war, when Keyi Hongyuan was ordered to be in danger, to the smooth shipment of the first high-energy excimer laser.

And photoresist is even more ridiculous.

It's an extremely small market.

In 2021, the global semiconductor photoresist market size combined was $9.18 billion.

Moreover, this is still the figure in the case of the domestic injustice, almost several times the price of the purchase.

The overall market size of photoresist has increased from 200 billion US dollars in 14 years to 9.18 billion in 21 years, and domestic manufacturers have made great contributions.

Before sending samples, photoresist manufacturers need to purchase lithography machines for internal formula testing and adjust the formula according to the verification results, while the lithography equipment is expensive and the one-time investment is large, and the market ceiling of photoresist itself is about 10 billion US dollars, which is why the development of the domestic photoresist industry has been slow in the past.

But this itself is the field of fine chemicals, which is actually another Huaguo's strength, and it can come out with a little tinkering.

The localization rate of semiconductor photoresist will be 0% in 2020, 1% in 2021, 7% in 2022, and 13% in 2023.

It may seem like a low number, but there is a very important factor in this, the introduction period.

Due to the complexity and diversity of photolithography in the chip manufacturing process, the needs of different photolithography processes and different manufacturers of the same lithography process are different, and photoresist manufacturers need to adjust the photoresist formulation to meet the differentiated needs.

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

But, not nothing.

In the case of Qingyun according to the map, he can even directly name which unit to do which.

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

Rich and powerful is the right to speak.

It's the same in the scientific community.

Cheng Jin, who understood, couldn't fully agree with Qingyun's opinion in his heart, but ......

What does this have to do with him?

For him, it was a deal.

Thinking of this, Cheng Jin turned his head to look at Qingyun, "What about the specific details?" I'm not going to stab him with a knife, am I? And ......"

Cheng Jin smiled, "With me, the 'father of Huaguo chips', you kid must want to blame others, right?" So it's not that rough. ”

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

Cheng Jin understood in seconds when he heard this, "What kind of hoopoe bird?" One for him, one for me? ”

At the beginning of the century, there was a lot of uproar about the assassination of Harid with a poison needle by the hoopoe bird Satsuma.

After the matter was made public, people learned that this thing was a feeding tool for agents back in the Cold War.

Coupled with the Pearl Port that Qingyun said just now, Cheng Jin instantly understood the plan.

Pearl Harbor, just right.

Special location, but in the territory of the country, how easy to operate.

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

Qingyun nodded, "There are professionals who will teach you how to do it." ”

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

After Cheng Jin moved his body, he looked at the cable tie in Qingyun's hand and smiled playfully, "You're not afraid that I will run when I open the door?" Or am I dying with you in my car now? ”

Qingyun shrugged his shoulders, "Teacher, I advise you not to be stupid." ”

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

Cheng Jin patted his work card in his hand, "Okay, this trip to the world is worth it." ”

Under normal circumstances, if he didn't cheat, he would never have given his son this treatment in his life.

And cheating, in fact, he knows very well in his heart that sooner or later it will be exposed, but he has always been unwilling to face the reality.

Because the funds are simply not enough to support him to lie.

Seeing that he was so cooperative, Qingyun was also completely relieved, scattered a cigarette, lit it for him with a fire, and then said sincerely,

"Teacher...... What else do you want? I can do what I can. ”

Cheng Jin glanced at him amusedly, "Worried that you won't be able to sleep at night in the future?" ”

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

After that, he thought for a moment, "I want to see my parents, wife and children, and see them for the last time." ”

Qingyun pondered for a moment when he heard this, and then said in embarrassment, "To be honest, I can only let you see you from afar." ”

Cheng Jin didn't have a depressed look.

He also knew very well in his heart that this was indeed embarrassing.

is willing to let him see him from afar, Qingyun also has to take risks.

He shrugged his shoulders, "Then forget it." ”

Between words, Cheng Jin handed back the work card in his hand to Qingyun, "You can keep it for me." ”

After that, he smiled freely, "This thing will definitely not let me carry it around."

And whether it's true or not, only you know.

If it's true, you also know how to use it to maximize my benefits.

So, over to you. ”

Qingyun was not polite, took it back and took it back to his pocket, then patted it, and said with a smile,

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

Cheng Jin threw the cigarette butt out the window, "What should I do now?" ”

Qingyun looked at his watch, "Now you need to change your car and follow them to the airport to take a plane to Pearl Port overnight." ”

With that, he put his hand out the window and gestured.

In the middle of the ring, several young men appeared on the side of Cheng Jin's door.

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

Qingyun, who was sitting in the car, was silent for a few seconds, and then chased out of the car and shouted at Cheng Jin's back, which was a deep bow.

"Disciple Qingyun, send off the teacher!"

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

Cheng Jin didn't look back, raised his hand and waved, didn't say anything, and went straight to the car.

The night was falling, and the stars dotted the sky, as if to see off Cheng Jin, who was about to leave.

The red-flashing taillights faded into the night, and finally disappeared into the darkness.
