Su Zhe looked at the exclaimed people with a smile on his face.
At this moment, Niu Guanghui and Si Wenbo were also extremely excited.
The two looked at the test data of the two sets of processed lenses on the big screen and knew that this time it was stable.
"Not bad, not bad! This is the result I want to see. Now everyone no longer has to guess and can feel at ease." Niu Guanghui said with a smile.
"Indeed! The two groups can have such detection data, which shows the stability of DYN-ion beam polishing technology." Si Wenbo said affirmatively, "Old cow! It would be great if the plasma EUV light source you developed breaks through. The EUV lithography machine we build will be competitive."
"I think so too! Our research team..." Before Niu Guanghui could finish speaking, Bao Zhengyi, who was standing on the stage, took the microphone and shouted again.
"Please note that there is still room for improvement in the test results of these two groups. In theory, DYN-ion beam polishing technology can achieve a mirror accuracy of 0.06 nanometers, a peak-to-valley surface accuracy and a surface roughness of 10 picometers."
"With DYN-ion beam polishing technology, we can enter the high-end optical lens market, the most typical one is EUV optical lens, the most..."
Su Zhe listened for a while and found that it was the same as Fan Xiaoming said, and began to look towards the future.
Niu Guanghui and Si Wenbo smiled.
"Old Niu! Let's continue." Si Wenbo said with a smile.
"Okay!" Niu Guanghui continued to talk about the problem of plasma EUV light source.
Su Zhe listened and calculated quickly in his mind.
The parameters related to Niu Guanghui were explained in detail, and he also pointed out the problem, and the tin droplets would become unstable under the irradiation of high-power infrared light with a wavelength of 10.6 microns, resulting in the inability to obtain ultraviolet light with a wavelength of 13.5 nanometers.
After hearing this, Su Zhe stopped listening to the discussion between Niu Guanghui and Si Wenbo, and just started doing calculations in his head.
Coincidentally, the principle of producing this plasma EUV light source has something to do with the ZGZ-atomic vibration model he studied.
Their large frames are the same, and atoms absorb electromagnetic waves of specific wavelengths in specific states, thereby releasing electromagnetic waves of specific wavelengths.
Relatively speaking, the ZGZ-atomic vibration model is a special case.
Su Zhe has experience in building a ZGZ-atomic vibration model and can calculate the EUV light source used by the EUV lithography machine much faster.
First, the state information of tin atoms is calculated, and then the reaction of tin atoms after absorbing infrared light with a wavelength of 10.6 microns is calculated...
Slowly, a model in which tin atoms absorb infrared light with a wavelength of 10.6 microns and release ultraviolet light with a wavelength of 13.5 nanometers appeared in his mind.
As for the instability of tin droplets under the irradiation of high-power infrared light with a wavelength of 10.6 microns, the reason is that the state of some tin atoms has changed under the irradiation of ultraviolet light.
Obviously, Niu Guanghui and the others knew the reason, and their improved method was to add other metals to the tin drops.
Through calculations, he found that this direction was correct, but there were strict requirements for the metal added and the proportion of metal added.
The purpose of adding other metals is to prevent the vast majority of tin atoms from changing the state information of the atoms under the irradiation of high-power infrared light.
Niu Guanghui and others tried to add more than 40 metals such as lithium, beryllium, aluminum, calcium, iron, platinum, gold, and silver.
Based on his experience in building the ZGZ-atomic vibration model and calculations, Su Zhe eliminated most of the metals in the periodic table of elements, leaving only three types, including beryllium, calcium, and barium.
By simple calculations, barium was abandoned, leaving beryllium and calcium.
Beryllium and calcium were brought into the calculations and beryllium was finally determined.
Continuing with the calculation of the ratios of beryllium and tin, three sets of ratios were determined.
In Su Zhe's opinion, these three ratios can maintain the state of tin atoms.
After doing these calculations, he saw that the time was already half past nine in the evening. The entire calculation process took him nearly two hours.
Only then did I realize that he was extremely hot and there was already a thin layer of sweat on his forehead.
He looked at the stage. Bao Zhengyi was still talking about the application of high-end optical lenses in lasers. The participants below were also excited to listen.
Sitting next to him, Niu Guanghui and Si Wenbo each held a small notebook and were calculating something in it.
"Old Niu! According to my calculations, among so many metals, adding calcium is the most likely. If you failed to add calcium, it is because you added the wrong amount." Si Wenbo handed the small book in his hand to Niu Brilliance.
Niu Guanghui took the small notebook, looked at it carefully, and calculated on the small notebook for a while, and said with a smile: "Yeah! It's a bit similar. I will try it according to this ratio when I get back. Lao Si, if this ratio becomes , I can’t make the decision on the tens of millions of bonuses, but the one million bonus is OK.”
"That's so embarrassing!" Si Wenbo smiled happily.
If it really comes to fruition, he can feel at ease with the money.
"It should be! It should be!" Niu Guanghui waved his hands, "This is to make money based on one's own skills. What's the point of being embarrassed if you don't steal or rob?"
"That's it! That's it!" Si Wenbo said with a smile on his face, "I really hope that the plasma EUV light source can make a breakthrough. I know best about the synchrotron radiation EUV light source. With the same chip, the latter consumes 20 times more energy than the former. Times, even if we build an EUV lithography machine, we will still be uncompetitive."
"Understood! I'm very clear about this, Lao Si. What I didn't expect was that you would have such a high level of awareness. You know, once the plasma EUV light source I develop is successful, the project you are doing will lose its meaning. If you say something unpleasant, your work will be in vain, do you really not care?" Niu Guanghui said seriously.
"It would be a lie to say that we don't care. After all, this is what our team has worked hard to do, but caring about the use is still not able to reduce the energy consumption of the synchrotron radiation EUV light source." Si Wenbo thought about it and said, "The synchrotron radiation EUV light source As a backup light source for EUV lithography machines, it can be used in emergency situations, but it cannot be used in mass production."
"Old Si! You are telling the truth. The burden on our shoulders is very heavy! If we want to achieve all-round transcendence, the first thing we need to do is to transcend science and technology." Niu Guanghui said firmly.
"Yes!" Si Wenbo said, looking at Su Zhe and saying in surprise, "Su Zhe! Why are your face flushed and your forehead sweating? This lecture hall has air conditioning, and it's not turned on low."
"My body is hot! I like to sweat." Su Zhe said casually.
"Then you should pay attention and drink more water." Si Wenbo reminded, "Su Zhe! Now the country is paying more and more attention to talents and scientific researchers. Geniuses like you must study hard. You heard it just now. I guess If the ratio is achieved, you can get a million-dollar bonus, so there is a future in scientific research."
"I know! I will study hard." Su Zhe nodded, "Um...Professor Niu, Professor Si, I understand everything you just said..."
"What? You understand, you understand everything." Si Wenbo looked surprised.
"Yes! I understand everything." Su Zhe said affirmatively, "Professor Niu! Can you give me the notebook and pen, and I will write down the three sets of ratios I calculated."
"What... give it to you." Niu Guanghui was a little confused, but still handed the small notebook and pen in his hand to Su Zhe.
Su Zhe took the notebook and pen and wrote three ratios of beryllium and tin in the notebook. After writing, he returned the notebook and pen to Professor Niu Guanghui.
"Add beryllium..."
"Three different sets of proportions. This..."
Niu Guanghui and Si Wenbo looked at the contents in the small book and were amazed.
