Chapter 243 Optical lenses also have a breakthrough!
Seeing Zheng Ronger's appearance, Lin Xiao burst out laughing, then rubbed her head and said with a smile: "When you're done, I'll take you to a big dinner."
"Really? I want to eat hot pot!"
"You can eat whatever you want."
"Great!"
Zheng Ronger cheered, then picked up the pen and started doing math problems.
Lin Xiao, who was next to her, was watching her steps in doing the questions to see if her thinking was correct.
After knowing Zheng Ronger for such a long time, he naturally became more and more fond of this sister. Since she wanted to become a female mathematician, he would naturally do his best to help her.
Sometimes strictness is also very necessary.
In this way, time passed quickly, and Lin Xiao did not embarrass her, so the question was not difficult, and even a bit simple. After thinking for a while, Zheng Ronger knew how to do it, and quickly solved the question.
Looking at her problem-solving process, Lin Xiao gave a thumbs up, "Well done, the ideas are also very good."
Putting down her pen, Zheng Ronger clapped her hands, raised her chin and said, "Humph, my studying for so long was not in vain!"
"Yes, yes." Lin Xiao smiled and rubbed her head, "Rong'er is the smartest."
"Don't rub my head!" Zheng Ronger took Lin Xiao's hand away and pouted, "My hair is all messed up."
Lin Xiao smiled, then stood up and said, "Okay, let's go eat hot pot now."
"Okay!" Zheng Ronger immediately forgot about her hair and stood up excitedly.
“I’m going to eat Haidilao!”
"You can eat whatever you want."
Lin Xiao said with a smile.
Then he began to prepare, and then he took Zheng Ronger away.
However, just as they were about to leave the office, Lin Xiao's cell phone rang.
I took a look and saw that it was a call from Academician Luo Gangxian.
Lin Xiao was stunned for a moment, and suddenly remembered what Luo Gangxian told him some time ago that the new encoder had been successfully developed and was just waiting to be debugged on their ion polisher. Looking at it now, is it a success?
The ion polisher they use is also developed by themselves, and they have a complete set of information on this ion polisher, so it is not difficult to upgrade it.
It's been so long now, could it be that it's getting better?
After answering the phone, he said: "Academician Luo, what's wrong? Is it something about the polishing machine?"
There was laughter from the other side of the phone: "Hahaha, it's not just that! It's not just a polishing machine, we've even finished the polishing!"
"Has the polishing been completed? You mean, the lenses have been polished?"
"That's right!" Luo Gangxian smiled happily, "Professor Lin, you are really amazing! After we used your mathematical model, our ion polishing machine is almost like automatic tracking and positioning, and it can be easily
Smooth out those red and blue areas on the lenses!"
"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 the news, Lin Xiao suddenly became happy. In this way, their country, China, will also have the world's top polishing technology!
One of the most critical technologies in this lithography machine has officially achieved a breakthrough in their hands!
Lin Xiao smiled and said: "Well done! Academician Luo, let's polish a few more pieces to open the eyes of foreigners!"
"certainly!"
Luo Gangxian responded, and then the two of them said no more and hung up the phone.
Lin Xiao's mood also improved.
Now that the optical lenses are done, the only remaining issues are the light source and the dual worktables.
The main issue with the double worktable is accuracy. Their current precision technology cannot guarantee its stability at all times. However, with the update of encoders, the double worktable will be able to achieve a breakthrough sooner or later.
As for the problem of light source, because Lin Xiao has a mature solution from Asmail 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
Conflicts arose over patents, which was why he had not directly copied the information in his mind before. It was all because of patent issues. He could avoid foreign infringement of rights and interests by applying for patents. Naturally, they had to abide by foreign patents.
Therefore, after its optimization, it can achieve the function of bypassing the patent by circumventing the other party's patent protection technical features, and even perform better than the other party's technology.
"In this way, it seems that it won't be long before we start assembling the photolithography machine?"
Lin Xiao couldn't help but think like this.
Zheng Ronger, who was standing next to him, saw him thinking and couldn't help but ask: "Brother Lin Xiao, what are you thinking about?"
Lin Xiao came back to his senses and said with a smile: "I didn't think about anything, let's go."
Then, he took Zheng Ronger and left the college happily.
…
Institute of Optoelectronics, Rongcheng, Sichuan Province.
Luo Gangxian hung up the phone to convey the good news to Lin Xiao, and then returned to their polishing room with a smile.
"How about the third piece?"
"47% has been processed, and it will take another day."
"Yeah." Luo Gangxian nodded.
The ion polishing process of a lens takes at least more than forty hours, nearly two days.
Of course, this time is considered a very normal time, because ion polishing needs to process every particle on it, so the speed is slow, which is normal. This is why it has become the most expensive lens in the world.
A small piece costs more than one million yuan, and the entire photolithography machine requires a combination of more than a dozen lenses, which is equivalent to nearly 20 million yuan.
Why Asmail produces very limited photolithography machines every year is largely due to the limited production of lenses. After all, only Zeiss could produce such high-precision lenses in the past.
But now, their country, China, can also produce it!
And the most important thing is that they don't need that kind of experienced polishing master.
With the help of Lin Xiao, they now directly use a mathematical model to replace the experience of these masters.
In other words, as long as they can build enough assembly lines, they will be able to easily produce enough lenses.
By then, Zeiss will directly lose its competitiveness because its production capacity lags behind them. By then, China will hope to replace Zeiss and become Asmail's sole supplier of optical lenses.
And even if Asmail still supports Zeiss, it won't be a big problem, at least they will have the best technology.
Of course, if they can build photolithography machines in China, then these lenses must be supplied to China first.
Although this seems to be a long way off, it is not without hope.
Why did Asmail suddenly agree to sell DUV lithography machines to China? Obviously, it was not just because the United States had no control over it, but because they saw that China seemed to be really ready to build DUV lithography machines, so they acted first.
.
If China really builds a DUV lithography machine, they will be in trouble.
But now, they have even made this kind of ultra-high-precision optical lens. There is no doubt that China is one step closer to building a photolithography machine.
Thinking of this, Luo Gangxian felt 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 is their turn to show off in the optoelectronics industry.
…
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 and successfully polished ultra-precision mirrors with a roughness of 50 to 90pm-RMS on optical lenses, achieving a major breakthrough in the field of optics.
The accuracy of this lens has reached the world's top level and can be used in the lenses of the most precise lithography machines. It is one of the most critical components in the lithography machine.
In the past, this level of lenses could only be produced by Zeiss in Germany, and the annual production capacity was extremely limited. However, our institute has achieved a major breakthrough in production technology, which can greatly increase production capacity...]
There are a lot of them, but one of the core themes is: strong yuppie.
Suddenly, people at home and abroad were in a frenzy.
Some time ago, Hua Guocai achieved a breakthrough in silicon wafer production. As a result, it has only been so long, less than a month, but it can actually produce ultra-precision optical lenses used in photolithography machines?
What is even said about achieving a major breakthrough in production capacity?
Are you copying the silicon wafer production capacity breakthrough into optical lenses?
However, this technology is much more difficult to implement than silicon wafers.
After all, there is only one company in the world, Zeiss, that can produce such ultra-high-precision lenses. All other companies and research institutions can only fall behind. However, there are so many manufacturers in the world that can produce silicon wafers, although they occupy the majority.
These are just those companies, but there are also many small silicon wafer manufacturers in the world, encroaching on those small markets.
Therefore, what Optoelectronics announced is far more attractive than other things.
Suddenly, countless people paid attention to this announcement, and the news even made it to the hot search list.
"I don't have much education, what kind of unit is pm-RMS?"
"PM is picometer, which is one thousandth of nanometer, nanometer is one thousandth of micrometer, micrometer is one thousandth of millimeter, which is equivalent to 1 millimeter equals 1 billion picometer, RMS is root mean square
Meaning, a mathematical estimation method, more detailed information on Baidu
"Thanks for the popular science, but what does this 50 to 90pm-RMS mean?"
"On a plane roughly the size of our country, the highest bulge cannot exceed 27 centimeters. If it is reduced by 27 times, then on a lens of 360,000 square kilometers, the highest bulge can only be 1
Centimeters, the difference is only the size of the land area of Germany.』
"Fuck!"
"Awesome!"
"This is one of the key technologies of lithography machines! In this way, doesn't it mean that we can achieve breakthroughs in dual worktable and light source technologies, and we can build lithography machines?"
"Yes!"
"Great!"
…
Chinese netizens are full of excitement about this news. 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.
China has achieved major breakthroughs in two technologies in the semiconductor industry chain?
This makes the response from abroad not enthusiastic, or, should be said, anxious.
