Chapter 497: Huaxia Opens Her Eyes to Li Yan
No one felt sorry that Li Yan was still trying to show off at this moment.

Everyone here has a quick mind, and it couldn't be clearer what the phrase "I'm late" means.

The expressions of several people changed rapidly, from frowning with loss and anxiety in the last second to smiling with excitement and joy in the next second.

Li Yan's perception was very strong now. In his eyes, the frowns of these people were slowly unfolding synchronously...

Quite funny.

In terms of the degree of surprise, 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 mentally prepared.

The news about Li Yan also means different things to them.

Of course, the bigwigs present here are all happy to see this happen. The lithography machine has really been conquered, which is good news for them.

But Shi Lei is, after all, the leader of the Huaxia lithography machine project on the surface. He feels a little uncomfortable that the project was conquered by others.

Although many people believe that Li Yan's involvement in the lithography machine project was also due to Shi Lei's keen eye for talent, without the joint efforts of Shi Lei, Linjiang and Huaxin International, Li Yan would not have been able to buy this lithography machine, and naturally there would have been no follow-up.

If packaged, HUST, Linjiang and Huaxin International can all say that they play an important role in this matter.

They will definitely package it this way.

But Shi Lei knew that if the problem could be solved by simply buying a lithography machine, HUST would have already solved it.

The real decisive factor is right in front of us - Li Yan is an outrageous genius.

He couldn't say he didn't feel frustrated.

In comparison, Secretary Huang and Huaxin International are in a much more relaxed mood. They are also benefiting from Li Yan's great achievements, and they are very happy.

Secretary Huang’s mind is already full of propaganda paths.

The two CEOs of Huaxin International think more. If possible, they would certainly prefer to develop lithography machines by themselves. It is uncomfortable for chip manufacturers to be controlled by foreign countries in terms of core technology.

Especially when they heard that the Lighthouse Country was willing to disregard its reputation simply because of the adverse impact of the Jiaolong phone on Pineapple, they felt a great crisis.

If they can force the recall of lithography machines today in order to restrict Future Technology, then can they simply stop Huaxin International from selling lithography machines in the future?
Will Huaxin International be able to develop its own lithography machines by then?
From a business perspective, making chips is also about making money. When it comes to breakthroughs in technology, you should do so if possible. It is simply impossible to force a breakthrough that requires a huge investment of resources and has no guarantee of success.

Li Yan got the job done, and they gained fame. Maybe they could even use this relationship to reach a strategic cooperation, and gain both fame and fortune.

And with this, it has taken a huge step forward and completely become the absolute leader in China's chip manufacturing industry.

The two CEOs were laughing so hard that their eyes were shining.

"What's the progress?" Shi Lei asked.

With just one sentence, everyone calmed down again.

Secretary Huang thought to himself, "How strange! Why do I really believe everything Li Yan says?"

My mood has flown too far and it’s hard to bring it back.

"It's the next step to make a real machine." Li Yan said, "Now that you are here, we can talk about the next step."

Shi Lei pondered and said, "That requires a lot of resources."

Li Yan invited the four people to his office. "It doesn't make sense to talk about it here. Everyone, follow me. Let's first make it clear that 'I can build a photolithography machine', and then talk about other things."

"We don't doubt you for what you said." Secretary Huang said with a smile.

"Then help me verify whether these things are good enough to convince others."

As soon as he entered the office, Shi Lei was shocked by the information scattered everywhere. "Have you read all this?"

"I haven't read the ones piled next to the bookshelf yet, I've finished reading the ones on the bookshelf, and the others scattered around... I guess they're all mixed up."

This kid...is not a human being.

"Everyone," Li Yan patted a few thick blueprints on the desk, "This is the blueprint of the photolithography machine."

Only Shi Lei flipped through it, but if he could determine whether it was feasible after just a few flips, 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 direct proof is this surveillance video."

Secretary Huang became excited when he heard the surveillance video.

He couldn't say a word of comment when looking at the drawings and models.

But why surveillance video? What can it prove?
The surveillance that Li Yan mentioned was naturally the video footage of him piecing together the lithography machine.

However, he deliberately concealed the time, then clicked on the five-fold speed, and still moved the progress bar.

Use acceleration that ordinary people can understand to cover up the normal speed that ordinary people cannot understand.

Li Yan's movements at normal speed were too fast and so precise that he looked like a robot, and he didn't look like a human.

There should be a limit to showing off, it’s okay to hide it a little.

If this level of abnormality is seen by others, it may lead to unfavorable 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 results.

"I dismantled this lithography machine and put it back together," said Li Yan.

Shi Lei and the CEO of Huaxin International were stunned.

Especially Mr. Liang, the chief engineer of Huaxin International.

Shi Lei couldn't help but sigh, "You kid, you really demolished it?"

"Disassembling it is not the point. I put it back together." Li Yan said, "Isn't being able to disassemble and reassemble it enough to prove that I understand this thing?"

"That's not necessarily true, right?" Secretary Huang raised an objection at this point. He obviously didn't understand the concept of disassembling and reassembling a precision machine with tens of thousands of parts. "Disassembling and reassembling doesn't necessarily mean it can be manufactured, right? I remember that one of the major difficulties with lithography machines is the process?"

"So I optimized it a bit. 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 bit."

"Optimize?" Mr. Liang's tone rose eight degrees. "You said you optimized it?"

Li Yan walked into the lounge with a smile and dragged out a box of clanging things. "I can even optimize other people's finished products, let alone my own designs?"

ah? ! !
Mr. Liang suddenly felt his eyes go dark and he even felt like his heart was stopping.

Mr. Fan, the general manager of Huaxin International, also found it incredible and immediately asked, "Did you remove some parts?"

"Yes."

“Does it work now?”

"Of course." Li Yan nodded. "The stuff is in the lab, but I don't have a matching production chain. You two are more familiar with it, so you can go take a look first, and then send it to Huaxin International for testing."

Mr. Liang was having a hard time holding back the words "This is impossible".

"That's not good," said Secretary Huang. "If something goes wrong during the bumpy ride, we won't be able to figure it out."

"It's not a big problem," Li Yan waved her hand, "I can fix it over there."

...?
Shi Lei suddenly clapped his hands and said, "Boss Fan, Boss Liang, let's do as Li Yan said. If it works normally after the test, it will be much easier for us to fight for resources later."

Of course, Huaxin International had no reason to refuse.

Several people later went to the laboratory to look at the lithography machine. Because the lithography machine itself was in a sterile room, they just looked inside through the transparent glass.

Mr. Liang stared at it for a long time, unable to hold back his doubts: "Mr. Li, please don't feel offended by my asking some questions, nor do I distrust you..."

"That's not necessary," Li Yan said with a smile, "It's just a communication, please go ahead."

"Is this a immersion DUV?"

"Yes."

"The lithography machine you mentioned that you designed is also an immersion type?"

"Yes, it comes with a more expensive infiltration system. Optimization will have to wait until later, and it will probably take some time to test."

"You mean, you didn't do the test?"

"I haven't made it yet, so I can't test it. I only have this device, and it's hard for me to get ultrapure water. Huaxin International has a ready-made one, so I asked you to test it."

Mr. Liang frowned, "Then why do you think your idea is feasible?"

"I have simulated it in my mind and on the computer. It's OK. Although my solution may not be consistent with Asuma's method - I also said that considering the current level of industrial production in China, the plan I have made for the time being is more like a 'lithography room' compared to a lithography machine. The cost of the immersion system is not at the mass production level, and I still need to optimize it according to the actual production situation."

...Hiss, Mr. Liang smacked his lips, thinking that he should just assume that what Li Yan said was true, and continued to ask:
"What about resolution and overlay accuracy?"

"It's the same as ASMA's, with a wavelength of 193, ArFi lithography machine, a resolution of 38nm, and thanks to the improvement of immersion, the minimum process is 7nm."

While listening to this, Mr. Liang kept shouting "Impossible" in his mind 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 manufacturing process. In actual use, if you want to achieve a 7nm process through multiple exposures, the yield rate should not be very good. It can only be considered as no problem in theory. In practical applications, the chips with a process of 28nm should still be the main focus."

"If what you said is true, you are the savior of this industry in China." President Fan praised President Liang and said, "You have completely led our country's chip industry to a higher level from scratch! Incredible!"

Mr. Liang continued to ask, "How could you dismantle the positioning and operation of the mask, wafer, light source and other modules by hand and then restore them without affecting their accuracy?"

"Mr. Liang, if the accuracy of the lithography machine depends on whether the hands shake during installation, it is too low-level. Even if it is installed on a fully mechanical assembly line, can the accuracy of large-scale equipment match the accuracy of the parts of the lithography machine?"

"That……"

"They must have matching positioning devices. Even the number of turns of the screws has specific regulations, and there is a slight adjustment margin. For example, the accuracy of the mask transfer module is different from that of the wafer transfer module and the dual wafer platform module. The accuracy can be gradually improved through the advancement of the process. How the internal operating procedures of this thing correct the positioning error is the core issue for the operation of the final product." Li Yan said, "This level of accuracy cannot be guaranteed by mechanical operations of 'how to place' alone."

Mr. Liang was very anxious to hear this. He had too many questions to ask:
"How can you tell how many turns a screw has?"

“I remembered it when I dismantled it.”

"Just... just rely on memory?" Mr. Fan was also confused.

This is too outrageous. A cool novel can't be so cool.

"Of course not. The screws will also wear out after being removed and screwed back in. After all, I am operating with my bare hands, so some parts cannot be exactly the same as before. So I need to fully understand the machine and understand why the screws need to be turned so many times. Then, with the help of the computer model, I can confirm how many times I need to turn the screws when I put them back in."

The good ones are even more outrageous.

"So what you said about the program operation... Did you directly analyze the internal operating system of the machine?"

"I wrote a new one." Li Yan said with a smile.

Mr. Liang suddenly felt a surge of hot blood in his chest, about to gush out.

He wanted to speak several times, but seeing that Li Yan had no way of asking, he finally shook his head and said, "I... don't have anything to ask, Mr. Fan. I want to ship it back now so that we can test whether we can make a 28nm chip."

Shi Lei was horrified when he heard this. He leaned close to Li Yan's ear and whispered, "You've dismantled the infiltration system. Can you still use it later?"

"I didn't really disassemble all the parts..." Li Yan said helplessly, "Not all parts can be disassembled, Shiyuan, I'm not replicating it one-to-one this time. For some things, you just need to understand its principles and then implement it in your own way."

"You told me before that I know the sizes, functions and relative positions of all the parts."

"You didn't believe me when I said that. If I said I was going to optimize it, see how others do it, and then implement it in my own way, wouldn't you just treat it as bullshit?"

"Hey," Shi Lei laughed, "I wouldn't dare to do that."

Li Yan shrugged, "And I really need to fully understand this machine before I can possibly make one myself."

"Please don't say that. My heart can't take it anymore today."

At the insistence of Mr. Liang, Mr. Fan brought in a professional team from Huaxin International to prepare to transport the lithography machine in Li Yan's laboratory back for testing.

Just the task of getting this thing safely back into the "packaging box" and onto the truck was enough to make everyone exhausted.

Mr. Liang kept sighing, "He said he disassembled it with his bare hands? Is he a god?"

Mr. Fan also joked, "Didn't you see there are a lot of small machines here? They are also for auxiliary purposes."

"I don't understand. I want to verify it immediately."

“What if it really works?”

"I'll take out the good old wine from my home and come here to worship the gods."

"Li Yan is a minor."

"I poured wine in front of the door of 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 on site to follow up.

Li Yan was pulled out by Secretary Huang to have a private conversation.

There is only one possibility for a leader of this level to whisper.

Deliver some higher level information.

"Li Yan, actually, compared to the lithography machine, I am more concerned about another thing now."

“Assembly line intelligent manufacturing?”

"Yes!" Huang Guohui's eyes lit up. "You have this project, but you didn't mention it when Tang Bu came before... assembly line intelligent manufacturing, is it now in the actual testing stage?"

Li Yan didn't expect this project to attract so much attention. "Yes, we are preparing for testing, an internal test, and looking for manufacturers of different sizes and with different needs to see if we can complete assembly line manufacturing according to their needs. The cost assessment will also be adjusted based on the results."

"Okay, very good. You must do a good job on this project. If you need any assistance, just let me know." Huang Guohui smiled and patted Li Yan's shoulder. Just patting was not enough, he even took her hand and said, "If you have anything, you don't have to go through the secretary, just come to me directly. I am not convenient to answer the phone during some meetings. I will call you back when I see you later."

What's going on? What's going on?

Li Yan felt Secretary Huang's enthusiasm a little confused.

"America has never stopped pressuring us. The country has always hoped that our industrial production can be fully independent and de-Americanized as soon as possible, and the production level of the entire industrial chain can be comprehensively improved... Li Yan, you have taken a step that we never imagined."

So that's it... Li Yan suddenly realized.

Secretary Huang sighed, "Li Yan, why do you want to do this? Is it for the lithography machine?"

Li Yan shook her head. "I didn't expect to get the technical support for the lithography machine through this. I just felt bad about being stuck at the industrial level, so I tried to find a way to solve it."

"In other words, you really want to improve the industrial level of the entire society?" Secretary Huang's eyes brightened, and he looked a lot younger.

"Of course," Li Yan said, "We can improve the industrialization level of the whole society and thus increase productivity. When productivity increases, the employment structure of society will change, and more creativity will be released. This is indeed one of the things I want to do. The birth of Jiaolong mobile phone is the same. It is not just for making money, but mainly to change everyone's life."

Secretary Huang was very excited, pacing around in the small courtyard, as if he had made a great decision, and solemnly pressed Li Yan's shoulder:

"The country has seen you, Comrade Li Yan."

"Ah?" Li Yan showed a very genuine look of shock, "You just saw it?"
