Chapter 497 China opens its eyes to Li Yan
No one lamented that Li Yan was still trying to show off right now.
Everyone here is thinking very fast. What does "late" mean? It really can't be clearer.
The expressions of several people changed rapidly, from the frowning expression of loss and anxiety in the last second, to the excitement and joy of raising the corners of the mouth in the next second.
Li Yan's perception is now very strong. In his eyes, the brows of these people are unfolding simultaneously and slowly...
Quite funny.
In terms of surprise level, Shi Lei was the least surprised, while the two CEOs of Huaxin International were the most surprised.
After all, Shi Lei had learned about the situation before, so he was somewhat mentally prepared.
The news about Li Yan also has different meanings to them.
Of course, the big guys here are happy to see the success. The lithography machine has really been conquered, which is good news for them.
But after all, Shi Lei was the leader of the Huaxia lithography machine project. He felt a little uncomfortable when the project was conquered by others.
Although in the eyes of many people, Li Yan's entry into the lithography machine project was due to Shi Lei's insight. Without the joint cooperation between Shi Lei, Linjiang and Huaxin International, Li Yan would not have been able to buy this lithography machine, and naturally he would not have been able to buy it. follow up.
If we package it up, Chinese Academy of Sciences, Linjiang, and Huaxin International can all say that they have a pivotal position in this matter.
They will definitely package it this way.
But Shi Lei knew in his heart that if he could just buy a photolithography machine, the Chinese Academy of Sciences would have conquered it long ago.
The real decisive factor is right in front of you - Li Yan is an outrageous genius.
He couldn't say he wasn't frustrated.
In contrast, Secretary Huang and Huaxin International were much more relaxed. They took advantage of Li Yan's great achievements, and they were not only happy but also happy.
Secretary Huang’s mind is already full of propaganda routes.
The two CEOs of Huaxin International think more. If possible, they would of course prefer to develop their own photolithography machines. Chip manufacturers are subject to foreign constraints in terms of root technology, which is uncomfortable no matter what.
Especially when I heard that the Lighthouse Country was willing to disregard their face just because of the negative impact of the Jiaolong mobile phone on pineapples, I felt a huge crisis.
Today, in order to limit future technology, we can force a recall of lithography machines. In the future, can we just stop selling lithography machines to Huaxin International?
Will Huaxin International be able to develop its own photolithography machines by then?
In business, the purpose of making chips is to make money. Breakthroughs in technology are something that can be made if possible. It requires a large investment of resources and cannot be guaranteed. It is absolutely impossible to do it.
Li Yan has done it, and they have gained fame. Maybe they can also use this friendship to reach a strategic cooperation, and gain both fame and fortune.
And it will take a big step forward and become the absolute leader in China's chip manufacturing industry.
The two bosses laughed so hard that their eyes gleamed.
"What's the progress?" Shi Lei asked.
In one sentence, everyone immediately calmed down again.
Secretary Huang thought to himself: "It's weird, why do I really believe what Li Yan says?"
My mood suddenly flew too far, and it was a bit difficult to take it back.
"The first step to make a real machine." Li Yan said, "Everyone is just here, we can talk about the next step."
Shi Lei pondered, "That requires a lot of resources."
Li Yan called the four people to his office, "It doesn't make sense to say anything here. Come with me, everyone. Let's make it clear about 'I can build a lithography machine' first, and then talk about other things."
"What you said, we didn't doubt you." Secretary Huang said with a smile.
"Then just help me verify whether these things are enough to convince others."
As soon as he entered the office, Shi Lei was shocked by the information scattered everywhere, "Have you read all these?"
"The ones piled next to the bookshelf haven't been read yet, the ones in the bookshelf have been read, and the others are scattered... I guess."
This kid...isn't human.
"Everyone," Li Yan patted several thick drawings on the desk, "These are the drawings for the lithography machine."
Only Shi Lei turned it over, but if he could turn it over so many times, he would be sure it was feasible. The lithography machine would have been named Shi long ago.
"I have a model of the lithography machine on my computer, but I think the most intuitive proof is this surveillance video."
As soon as he heard the surveillance video, Secretary Huang became excited.
Looking at the drawings and models, he couldn't even comment on them.
But why surveillance video? What does this thing prove?
The surveillance Li Yan was talking about was naturally the video of him putting back the lithography machine.
However, he deliberately hid the time, then clicked on the five times speed, or pulled the progress bar.
Covering up the normal speed that ordinary people cannot understand with acceleration that ordinary people can understand.
At normal speed, Li Yan moves too fast, and his movements are as precise as a robot, and he doesn't look like a human being.
You need to have a certain amount of pretense, and it’s okay to hide it for a while.
If an abnormal state of this level is noticed by others, there may be unpleasant consequences.
Li Yan also deliberately did not mention how long it took him to assemble it, so as to draw everyone's attention to the result.
"I dismantled this photolithography machine and put it back together," Li Yan said.
Over there, Shi Lei and the boss of Huaxin International were stunned.
Especially Mr. Liang, the chief engineer of Huaxin International.
Shi Lei couldn't help but sigh, "You kid, are you really cheating?"
"It's not the point to dismantle it, I put it back together." Li Yan said, "Being able to dismantle and install it is enough to prove that I understand this thing?"
"That's not necessarily... right?" Secretary Huang raised an objection at this time. He obviously didn't understand the concept of disassembling and reassembling a precision machine with tens of thousands of parts. "Disassembly and reassembly does not necessarily mean that it can be Is it right? I remember that another major difficulty with photolithography machines is the process?”
"So I optimized it. Although it increased the cost a bit, I think... with China's current industrial level, it won't be a problem if we concentrate our efforts a little."
"Optimization?" Mr. Liang's tone raised an octave, "You said you optimized it?"
Li Yan walked into the lounge with a smile and pulled out a box of tinkling things. "I can even optimize other people's finished products, let alone the ones I designed myself?"
ah? ! !
Mr. Liang suddenly felt his eyes darken, and even felt as if his heart had stopped.
Mr. Fan, general manager of Huaxin International, also found it incredible and immediately asked, "Have you removed some parts?"
"Yes."
"Will it work now?"
"Of course." Li Yan nodded, "The things are in the research laboratory, but I don't have the supporting production chain. You two are familiar with each other, so you can go take a look first, and then send it to Huaxin International for testing."
Mr. Liang had a hard time holding back the sentence "This is impossible."
"This is not good," Secretary Huang said. "If something goes wrong along the way, we won't be able to figure it out."
"It's not a big problem," Li Yan waved his hand, "I can just go over there and repair it."
...?
Shi Lei suddenly clapped his hands and said, "Mr. Fan, Mr. Liang, just do as Li Yan said. If it can run normally after the test, it will be much easier for us to fight for resources later."
Huaxin International certainly has no reason to refuse.
Subsequently, several people went to the research laboratory to see the lithography machine. Because the lithography machine itself was in the sterile room, they just looked in through the transparent glass.
I can't see why. Mr. Liang stared at it for a long time. He really couldn't hold back the doubts in his heart: "Mr. Li, I ask some questions. Please don't feel offended. It's not that I don't trust you..."
"It doesn't have to be like this," Li Yan said with a smile, "It's just communication, please speak."
"Is this an immersion DUV?"
"Yes."
"The photolithography machine you designed yourself is also an immersion type?"
"Yes, it comes with a more expensive infiltration system. Optimization will have to wait for follow-up, and it will probably take a period of testing."
"You mean you didn't test it?"
"I haven't even made it, so I can't test it. I only have this thing in hand, and it's not easy for me to deal with ultrapure water or something like that. Huaxin International has it ready-made, so I asked you to test it."
Mr. Liang frowned tightly, "Then why do you think your idea is feasible?"
"I've simulated it in my mind and on the computer, it's OK. Although my solution is not necessarily consistent with Asma's approach - I also said that considering the current level of industrial production in China, compared with the lithography machine , the first plan I am working on is more like a 'photolithography room'. The cost of the infiltration system is not at the mass production level, and I still need to optimize it based on the actual production situation."
...Hiss, Mr. Liang pouted, thinking that what Li Yan said was true, he continued to ask:
"What about resolution and overlay accuracy?"
Please...you...collect 6...9...books...!
"Same as Asma's, 193 wavelength, ArFi lithography machine, resolution 38nm, thanks to the improvement of immersion, the minimum process is 7nm."
Mr. Liang was shouting "impossible" while listening in his heart, until he was exhausted.
Li Yan suddenly slapped his head and added, "Of course, the current overlay accuracy is limited by the accuracy of the production process. In practice, if you want to achieve the 7nm process through multiple exposures, the yield rate should not be good. It can only be regarded as no problem in theory. , for practical applications, chips with 28nm process should be the main ones.”
"If what you say is true, you will be the savior of China's industry." Mr. Fan shouted out the impossibility in Mr. Liang's heart with praise, "You will lead our country's chip industry from scratch. It’s incredible!”
Mr. Liang continued to ask, "You can actually disassemble and restore the positioning and operation of modules such as masks, wafers, and light sources by hand without affecting their accuracy?"
"Mr. Liang, if the accuracy of the photolithography machine depends on whether the hand shakes during installation, that would be too low-level. Even if it is a fully mechanical assembly line installation, can the accuracy of large equipment match the accuracy of the parts of the photolithography machine?" < br>
"Then..."
"They must all have matching clamping devices. Even the number of turns of the screws is specified, and there is a slight margin for adjustment. The accuracy of the mask transfer module is much better than that of the wafer transfer module and the dual The accuracy requirements of wafer platform modules are also different, and the accuracy can be adjusted The process is gradually improving. How to correct the positioning error in the internal operation program is the core issue for the final product to work, "Li Yan said, "This level of accuracy cannot be achieved solely by 'placement'. Mechanical operation guaranteed.”
Mr. Liang listened very anxiously. He had too many questions to ask:
"How do you know how many turns a screw has to take?"
"I remembered it when I took it apart."
"Just...just rely on memorization?" Mr. Fan was also confused.
It's too outrageous, and cool articles can't be so cool.
"Of course not. There will be some wear and tear after the screws are removed and screwed back. After all, I operate with bare hands, and some parts cannot be exactly the same as before. So you need to fully understand this machine, understand why the screws here turn so many times, and then use the help of computer models to Make sure I need to turn it a few times when putting it back on.”
The good ones are even more outrageous.
"Then what you said, program operation...did you directly analyze the internal operating system of the machine?"
"I wrote a new one." Li Yan smiled.
Mr. Liang suddenly felt a surge of hot blood in his chest, and it was about to spurt out.
He wanted to speak several times, but saw that Li Yan couldn't ask at all, and finally shook his head, "I... I have nothing more to ask, Mr. Fan, I want to ship it back now. Let's test whether we can make 28nm." Process chip. ”
Shi Lei was frightened when he heard this. He leaned into Li Yan's ear and asked quietly: "You have dismantled the infiltration system. Can it still be used again?"
"It's not like I really dismantled all the parts..." Li Yan was helpless, "Not all parts can be dismantled. Shiyuan, I'm not recreating them one to one this time. Some things only need to be understood by understanding their principles, and then Just do it in your own way.”
"All the parts you told me about before have their sizes, functions, and relative positions."
"You didn't believe what I said at the time. If I said that I was going to optimize, see what others do and then implement it in my own way, wouldn't you just think that I was farting?"
"Hey," Shi Lei smiled, "I don't dare."
Li Yan shrugged, "And I really need to fully understand this one before I can build one myself."
"Stop talking, my heart can't stand it today."
At Mr. Liang's insistence, Mr. Fan invited a professional team from Huaxin International to transport the lithography machine from Li Yan's laboratory back for testing.
Just how to safely get this thing back into the "box" and transport it to the car made everyone frustrated.
During this period, Mr. Liang kept sighing, "What the hell did he say he disassembled and assembled with his bare hands? A god?"
Mr. Fan also joked a few words, "Didn't you see that there are a bunch of small machines here? They are also auxiliary."
"I don't understand, I want to verify it immediately."
"What if it really works?"
"I will take out the old wine at home and come here to worship the gods."
"Li Yan is underage."
"I pour wine in front of the future technology!"
Of course, these words were not said in front of Li Yan.
The loading work took a long time, and Shi Lei and Wang Zi stayed at the scene to follow up.
Li Yan was dragged out by Secretary Huang to whisper.
There is only one possibility for a big leader of this level to whisper.
Convey some higher level information.
"Li Yan, actually I am more concerned about another thing than the photolithography machine."
"Intelligent manufacturing of assembly lines?"
"Yes!" Huang Guohui's eyes lit up, "You have this project, but you didn't talk about it when Tang Bu came here... assembly line intelligent manufacturing, is it now in the actual testing stage?"
Li Yan did not expect that this project would attract so much attention, "Yes, we are ready for testing. It is considered an internal test. We have found some manufacturers of different sizes and needs, large, medium and small, to see if we can complete assembly line manufacturing and cost assessment according to their needs. It should also be adjusted based on this result.”
"Okay, very good. You must do a good job on this project. If you need any assistance, just ask." Huang Guohui smiled and patted Li Yan on the shoulder. Patting alone was not enough, and he even took it directly. "If you have anything, you don't need to go through the secretary." Yes, call me directly. There are some meetings where it is not convenient for me to answer the phone. If you see me later, I will definitely call you back.”
What's going on? What's going on?
Li Yan felt a little confused about Secretary Huang's enthusiasm.
"The United States has never stopped putting pressure on us. The country has always hoped that our industrial production can be fully autonomous and de-beautified as soon as possible, and comprehensively improve the production level of the entire industry chain... Li Yan, you have taken a step we never imagined. Ah.”
It turned out to be this... Li Yan suddenly realized.
Secretary Huang sighed, "Li Yan, why do you want to do this? For the photolithography machine?"
Li Yan shook his head, "I didn't put any hope in getting the technical support for the lithography machine. I just felt uncomfortable that it was stuck at the industrial level, so I tried to find a way to solve it."
"In other words, you do have the idea of improving the industrial level of the whole society?" Secretary Huang's eyes brightened, and he looked much younger.
"Of course," Li Yan said, "Improving the industrialization level of the entire society will increase productivity. When productivity increases, society's employment structure will change and more creativity will be liberated. This is indeed one of the things I want to do... The same is true for the birth of Jiaolong Mobile. It is not just to make money, but mainly to change everyone’s life.”
Secretary Huang was very excited and kept pacing in the small courtyard. He seemed to have made a lot of determination and solemnly held Li Yan's shoulders:
"The country has seen you, Comrade Li Yan."
"Ah?" Li Yan showed a very sincere expression of shock, "Did you just see it?"
