From Almighty Scholar to Chief Scientist

Chapter 244 The optical lens also breaks through!

Seeing Zheng Ronger's appearance, Lin Xiao laughed, then rubbed her head and said with a smile: "It's done, brother will take you to have a big meal."

"Really? I want to eat hot pot!"

"You can eat whatever you want."

"Great!"

Zheng Ronger cheered, then picked up a pen and started doing math problems.

And Lin Xiao next to her was watching her steps to solve the problem, to see if her thinking was correct.

Having known Zheng Rong'er for so long, of course he has become more and more fond of this younger sister. Since she wants to become a female mathematician, he will naturally do his best to help her.

Sometimes strictness is also very necessary.

In this way, time passed quickly, and Lin Xiao didn't make things difficult for her, so the problem was not difficult, and even a little simple. After thinking for a while, Zheng Rong'er knew what to do, and quickly solved the problem.

Looking at her problem-solving process, Lin Xiao gave her a thumbs up, "It's a good job, and the thinking is also very good."

Putting down the pen, Zheng Rong'er clapped her hands, raised her chin and said, "Hmph, my study for so long is not in vain!"

"Yes, yes." Lin Xiao rubbed her head with a smile, "Rong'er is the smartest."

"Don't rub my head!" Zheng Rong'er took Lin Xiao's hand away, pouted and said, "Hair is all messed up."

Lin Xiao smiled, then got up and said, "Okay, let's go eat hot pot now."

"Okay!" Zheng Rong'er immediately forgot about her hair and stood up excitedly.

"I'm going to eat Haidilao!"

"Eat whatever you want."

Lin Xiao said with a smile.

Then he began to prepare, and then he was going to leave with Zheng Rong'er.

However, just as they were about to leave the office, Lin Xiao's cell phone rang.

After a glance, it was a call from Academician Luo Gangxian.

Lin Xiao was taken aback for a moment, and suddenly remembered what Luo Gangxian told him some time ago, the new encoder has been successfully developed, and they are waiting to debug their ion polishing machine. Looking at it now, is this a success?
The ion polishing machine they use is also developed by themselves, and they have a full set of information on this ion polishing machine, so it is not difficult to upgrade it.

It's been so long now, is it okay?

After connecting the phone, he said, "Academician Luo, what's the matter? Is it about the polishing machine?"

Laughter came from the phone: "Hahaha, not only! It's not just a polishing machine, we've even finished polishing!"

"Has the polishing been done? You mean, the lenses have been polished?"

"Yes!" Luo Gangxian smiled happily, "Professor Lin, you are amazing! After we use your mathematical model, our ion polishing machine is just like automatic tracking and positioning. Smoothed out those red and blue areas on the lens!"

"Now, we have polished two picometer-level optical lenses, one with a surface accuracy of 80pm-RMS and the other with a surface accuracy of 50pm-RMS!"

Hearing this news, Lin Xiao immediately became happy. In this way, Huaguo will also have the world's top polishing technology!

One of the most critical technologies in this lithography machine has officially made a breakthrough in their hands!
Lin Xiao smiled and said, "Good job! Academician Luo, let's polish a few more dollars to open the eyes of foreigners!"

"Of course!"

Luo Gangxian responded, and then the two stopped talking and hung up the phone.

Lin Xiao's mood also improved.

The optical lens is done, and the rest is the two problems of the light source and the double workbench.

The main problem of the double worktable is the accuracy. Their current precision technology cannot guarantee that it will always be stable. However, with the update of the encoder, the double workbench will be able to achieve a breakthrough sooner or later.

As for the problem of the light source, because Lin Xiao has a mature solution from Asmer EUV lithography machine in his mind, this is not a problem for him. All he needs to do is to optimize this solution to avoid There was a conflict on patents, which is why he didn't directly copy the materials in his mind before. It was all because of patent issues. He could avoid foreign infringement of rights by applying for patents, and they naturally had to abide by foreign patents.

So after his optimization, he can circumvent the technical features of the other party's patent protection, realize the effect of bypassing the patent, and even perform better than the other party's technology in terms of performance.

"In this way, it seems that it will not be long before we start assembling the lithography machine?"

Lin Xiao couldn't help but think this way.

Seeing him thinking, Zheng Rong'er beside him couldn't help asking: "Brother Lin Xiao, what are you thinking?"

Lin Xiao came back to his senses, smiled and said, "I didn't think about anything, let's go."

Then, he took Zheng Rong'er and left the academy happily.

……

Sichuan Province, Rongcheng, Photoelectric Institute.

Luo Gangxian hung up the phone to convey the good news to Lin Xiao, and then returned to their polishing room with a smile on his face.

"How about the third piece?"

"47% has been processed and it will take another day."

"En." Luo Gangxian nodded.

The ion polishing process of a lens takes at least more than 40 hours, nearly two days.

Of course, this time is a very normal time, because ion polishing needs to process every particle on it, so the speed is slow and normal, which is why it will become the most expensive lens in the world.

A small piece is as high as more than 100 million yuan, and the entire lithography machine needs such a combination of more than a dozen lenses, which is equivalent to nearly 2000 million yuan.

Why Asmer produces very limited lithography machines every year is largely related to the limited production of lenses. After all, only Zeiss was able to produce such high-precision lenses in the past.

But now, Huaguo can produce it!

And most importantly, they don't need the kind of experienced master polisher.

With Lin Xiao's help, they now directly replace the experience of these masters with a mathematical model.

In other words, as long as they can build enough assembly lines, they will be able to easily produce enough lenses.

At that time, Zeiss will directly lose its competitiveness because its production capacity will lag behind them. At that time, Huaguo will hope to replace Zeiss and become the sole supplier of optical lenses for Asmer.

And even if Asmer wants to support Zeiss, that's not a big problem, at least they will have the best technology.

Of course, if they can manufacture lithography machines in China, then these lenses must be supplied to China first.

Although this seems to be some distance away, it is not hopeless.

The reason why Asmer suddenly agreed to sell Huaguo DUV lithography machine is obviously not just because the United States can’t control it, but because they see that Huaguo seems to really have a posture to build a DUV lithography machine, so they act first. .

If Huaguo really builds a DUV lithography machine, they will be out of luck.

But now, they have even manufactured this kind of ultra-high-precision optical lenses. There is no doubt that Huaguo is one step closer to building a lithography machine.

Thinking of this, Luo Gangxian became even more excited.

It's time to find a time to spread the news.

People in the silicon industry have been showing off to the world for a long time, and now, it's their turn to show off in optoelectronics.

……

A few days later, the Institute of Optoelectronics officially issued an announcement.

[Our institute has successfully achieved a breakthrough in ultra-precision optical manufacturing technology, successfully polished an ultra-precision mirror surface with a roughness of 50 to 90pm-RMS on the optical lens, and achieved a major breakthrough in the field of optics.

The precision of the lens has reached the world's top level, and it can be used in the lithography machine lens of the most precise instrument, and is one of the most critical components in the lithography machine.

In the past, this level of lens was only produced by German Zeiss company, and the annual production capacity was extremely limited, but our company has achieved a major breakthrough in production technology, which can greatly increase production capacity...]

There are a lot of blah blah blah blah, and one of the core gist is: a strong yuppie.

Suddenly, both at home and abroad were boiling.

Some time ago, Hua Guocai achieved a breakthrough in the production of silicon wafers. As a result, how long has it been, less than a month, and even the ultra-precision optical lenses used in lithography machines can be produced?

What did you even say, a major breakthrough in production capacity has been achieved?

Are you replicating the breakthrough in silicon wafer production capacity to optical lenses?

But this technology is much more difficult to implement than silicon wafers.

After all, there is only one Zeiss company in the world that can manufacture such ultra-high-precision lenses. Only those companies are the only ones, but there are also many small silicon wafer manufacturers in the world, encroaching on those small markets.

Therefore, the matter announced by Optoelectronics is far more attractive than other matters.

All of a sudden, countless people paid attention to this announcement, and even this news was on the hot search list.

"I don't read much, what is the unit of pm-RMS?" 』

"PM is a picometer, which is one-thousandth of a nanometer, and a nanometer is one-thousandth of a micron, and a micron is one-thousandth of a millimeter, which is equivalent to 1 millimeter equals 10 billion picometers, and RMS is the root mean square. The meaning, a method of mathematical estimation, more detailed self-Baidu』

"Thanks for popular science, but what does this 50 to 90pm-RMS mean? 』

"On a plane roughly equivalent to the size of our country, the highest protrusion cannot exceed 27 centimeters. If it is reduced to 27 times, it is about 36 square kilometers on the lens, and the highest protrusion can only be 1. centimeters, less than the size of Germany. 』

"Fuck! 』

"Awesome! 』

"This is one of the key technologies of the lithography machine!In this way, doesn't it mean that we still have breakthroughs in the two technologies of dual workbench and light source, and we can build lithography machines? 』

"yes! 』

"Great! 』

……

Netizens in Huaguo are full of excitement about this news, and it seems that they are not far away from building a lithography machine in China.

At the same time, the response from foreign countries was even more enthusiastic.

Huaguo has achieved major breakthroughs in two technologies in the semiconductor industry chain?

This makes the response from foreign countries not enthusiastic, or, it should be said, anxious.
