Does Chapter 48 mean that the people in AS Company are too stupid?
“I designed it myself.”
Luo Yao's eyes met Yang Ming's.
There was no emotion in Luo Yao's eyes. Yang Ming couldn't see through Luo Yao's thoughts, but his intuition told him that if Luo Yao really did it, it could be selected into the collection of Arabian Nights stories.
Yang Ming asked tentatively, "Young comrade, this is no joke. Even the Ugly Country hasn't mastered the EUV lithography light source system technology yet. Are you sure you designed it yourself?"
Luo Yao had known the other party would ask this question, so he quickly explained the principle: "There are generally two types of lithography machines, one is DUV and the other is EUV. DUV uses a light source with a wavelength of 193 nanometers, while EUV uses a light source with a wavelength of 13.5 nanometers."
"According to the Rayleigh criterion R = D / 1.22, it can be concluded that the size that an optical system can resolve is proportional to the wavelength."
"So if you want to make smaller chips, you need light with a shorter wavelength, which is EUV light source."
"In fact, we all know that EUV light sources still use 193-nanometer light, but by using it to hit liquid metal tin twice in succession, we can get 13.5-nanometer light."
"Everything up to this point is pretty simple, but the most difficult part is the components in its optical system, namely the lenses."
Yang Ming nodded as he listened.
The cost of the lens accounts for about 40% of the entire lithography machine, which is quite expensive.
The lens of a photolithography machine is like a camera lens, consisting of lenses of different shapes.
If you want to better understand the lithography machine, you can also say that it is a large camera.
The difference is that ordinary cameras are used to take pictures of girls, while photolithography machines are used to copy integrated circuit patterns onto wafers through the principles of exposure and development.
So the lens is just like the camera lens, the main feature is that it is expensive.
Even the magical lens for shooting the moon has to call the lithography machine lens "Dad".
There are more than 20 lenses on the lithography machine. Currently, only three foreign factories can produce them, while China is still in the research and development stage.
"This lens stumped us at first. The transmittance and smoothness of the lenses produced by the leader aircraft could not be as good as those produced in foreign countries. The effect of light reflected from them was completely unusable." Yang Ming felt sad when he talked about this.
"We really lost a lot because we didn't develop semiconductors in the 1970s," Yang Ming lamented.
Luo Yao looked at Yang Ming's face, which was filled with regret. After a moment's thought, he decided to come clean: "The technical difficulties of the lens are actually all in this hard drive."
As he spoke, Luo Yao took out his red hard drive and placed it on the conference table.
The other four people in the conference room looked at the red hard drive on the table in silence.
Is the cutting-edge lens technology inside the red hard drive?
How is this possible?
Just when everyone was hesitating, Rao Huiling could no longer sit still and she reached out and took the hard drive.
"Let's take a look first."
Rao Huiling took the computer, connected the hard drive, and began to read. After a while, she looked at the screen in disbelief and said, "The optical crystal of the lens is extremely special. Only the finished crystal of high-purity rare earth halide can meet the performance requirements."
"Luo Yao, how did you come up with this?"
"calculate."
"I calculated the crystal impact of each rare earth and finally locked on high-purity rare earth halides."
Yang Ming was a little excited when he heard this and said, "It is indeed a high-purity rare earth halide. We have calculated this before."
"Look, this document covers not only lens technology, but also photoresist technology, the workbench system, projection lens system, mask stage system, automatic calibration system... basically all the engineering documents for the lithography machine are included in it."
Hearing what Rao Huiling said, Yang Ming took the computer with a serious face and started looking at it with the person next to him.
The entire document not only includes technology and principles, but also the dimensions of each component!
Even the specifications and materials of a screw are clearly written.
To put it bluntly, what is presented to them is a fool's guide to manufacturing lithography machines, which can be said to be a step-by-step guide to teaching people how to manufacture lithography machines.
But is this technology correct?
After Fu Daobin quietly exchanged opinions with the experts he brought with him, he asked Luo Yao, "Luo Yao, are you sure this document didn't come from abroad?"
"No, I'm a 16-year-old. Where can I get such detailed information?" Luo Yao thought Fu Daobin's question was strange.
"If I can get a full set of lithography machine technology from AS Company, does that mean that the people at AS Company are too stupid?" Luo Yao commented bluntly.
Luo Yao's words reminded Fu Daobin.
He was just a 16-year-old kid from a small town. How did he get it? And they had recently sent someone to follow him. Besides his company and his family, he had no social interactions with anyone else.
How could AS Company leak such complete technology after so many years of strict security?
Now it seems that the only explanation is that all of this was really designed by Luo Yao himself.
Huaji Company reported to Fu Daobin that Luo Yao's IQ was above 230, which alleviated Fu Daobin's doubts about Luo Yao's ability to come up with lithography machine technology.
But this is where the problem comes in.
Do you want to verify the model according to the engineering design drawings provided by Luo Yao?
"Professor Yang, and Professor Shi, what do you think?"
Shi Lin had been silent until Fu Daobin mentioned him. He then said, "I've only taken a quick look at it, and some of the principles are consistent with our previous research results."
"I want to ask Luo Yao, why did you say you wanted to dismantle the machine?"
Shi Lin knew that based on Luo Yao's level, his idea of dismantling the machine would definitely not be the same as Husky's idea of dismantling the house, so Shi Lin felt that the reason for dismantling the machine was very likely the key information.
"Because I haven't proven whether my idea is correct, although these documents are very detailed, without the materials and the help of a professional team, I can't build a model for verification."
After the first use of Pangu EDA, Luo Yao actually knew that the technology provided by the system was absolutely not diluted, but others did not know this.
So Luo Yao decided to take a step back and took the initiative to ask for verification.
Sure enough, Luo Yao said this.
Fu Daobin readily agreed: "Then, it's useless for us to just talk here. Let's speed up and form a team of experts to conduct theoretical research and build a model!"
"Okay, that's what we mean. This design plan still needs to be proven." Shi Lin agreed.
"Luo Yao developed Pangu EDA last time. Maybe this time he can really help us find the right way to build a lithography machine."
Fu Daobin was extremely excited. If Luo Yao could provide the technology they had been pursuing for a long time just like last time, then the current dilemma might be solved!
"Pangu EDA was also developed by Luo Yao?" Yang Ming, the only one in the conference room who didn't know about this, thought he had misheard when he first heard this.
It was not until Fu Daobin confirmed it that he realized how valuable the engineering design documents Luo Yao provided at this moment were.
"Director Fu, can I participate in the verification process?" Yang Ming had a small spark of hope in his heart at this time.
He had fantasized many times that one day he would be able to lead his team to find the key to manufacturing lithography machines, but the results were very limited.
Now, there is an opportunity that may allow him to witness the birth of lithography technology in China with his own eyes, and he certainly wants to participate.
"Professor Yang, of course you have to participate. This time the verification must be fast, otherwise we don't know what actions the other party will take next."
"Don't worry, Director Fu. We'll complete the task! We'll work all night long!"
Yang Ming is now in his forties and is no longer young, but he knows that China urgently needs an independent lithography machine to get out of trouble!
In this situation, Yang Ming felt like he was back to ten years ago, when he was full of energy.
Fu Daobin made several phone calls to arrange for experts to rush to the lithography machine research institute, which was still in its infancy, overnight.
When the experts received the call, they were all confused and anxious, wondering if they had encountered some difficult problem.
The problem of the lithography machine cannot be solved easily. I don’t know when it will be solved.
When they arrived at the research institute, they found that their leader had given them a blueprint of the entire process of manufacturing the lithography machine.
The experts were horrified and wanted to know the origin of the drawings, but their leader only said two words: "confidential."
"Anyway, since this was our idea, you guys need to follow up on the verification. The leaders above are taking this very seriously, and time is running out. We need to complete the model verification within two months."
Two months?!
Things are really rushing.
But no one in the institute had any objections; instead, they were all excited.
Because they know that if they are a step late, they will be treated unfairly.
If they are a step late, they will be the fish on the display board.
If you delay a step, the humiliation you will suffer will increase!
At this moment, they must take action to wash away the humiliation they once suffered!
The other side.
The news that Luo Yao had taken out the engineering design drawings of the lithography machine had already reached the ears of Huaji's president's office.
After the people in the president's office repeatedly asked Rao Huiling for details, they fell silent for a while.
The seven of them usually boasted that their insight was much higher than that of ordinary people, but at this moment they could not see through Luo Yao.
"Mr. Zheng, do you think the lithography machine that Luo Yao took out is real or fake? Where did it come from?" Lu Gao frowned, feeling that it was incredible that Luo Yao had found the technology for the lithography machine by himself.
Zheng Housheng pondered for a moment and then said, "You can't look at this problem from the perspective of an ordinary person."
"Luo Yao possesses an exceptionally high IQ. Based on this alone, his achievements in research and development will undoubtedly surpass others."
"Plus, Luo Yao is very hardworking. You see, he didn't rest after returning. He went to the library every day to read books related to lithography machines. This shows that Luo Yao's ability to draw those engineering drawings was definitely not something he achieved overnight."
"Besides, what's his purpose in giving us fake technology? To hinder our research and development progress?"
