Liu Jingying was still immersed in this joy at this moment. Seeing that Xu Yun's face had no expression change, he felt ashamed of this calm performance and quickly calmed down his emotions.
Of course, everyone is still discussing this topic, marveling at Xu Yun's talent in the field of materials research and development.
"Professor Xu."
"You should already know the purpose of the materials you developed, right? Are you just asking me to test it to create a surprise?"
At this time, Liu Jingying spoke again, a complicated smile appeared on the corner of his mouth and told his previous speculation.
High-end photoresist synthesis technology has been monopolized by Neon, which almost occupies most of the world's high-end photoresist market.
It has become the most indispensable part of the chip manufacturing process.
Other companies have never stopped researching photoresists, but they can only operate in the mid- to low-end market.
It has never been able to enter the high-end market.
In addition to Neon's firm dominance of the market, which prevents other photoresists from entering the supply chain, there is also the difficulty of the high-end photoresist production process.
Because it is used for etching chips of several nanometers, all data must be extremely precise and there is no room for sloppiness.
It's too difficult to develop.
Although Xu Yun is very talented in the field of materials and has solved coating materials and solid-state batteries in just one year, she must not believe that she can synthesize high-quality high-end photoresist in just a few days. Be skeptical.
In this case there is only one explanation.
Xu Yun probably started researching photoresist materials very early and successfully synthesized a sample not long ago.
It’s not that the purpose of the material is completely unknown.
After hearing all Liu Jingying's words, Xu Yun did not expect that the other party would make such a speculation.
However, it is really difficult to explain in detail the new material synthesis technology rewarded by this task. Anyway, with previous achievements in many fields, no one would doubt it.
With his thoughts stuck here, he coughed twice and cleared his throat, then spoke to Liu Jingying.
"The ability to develop this material is partly due to luck. I synthesized it by accident during the experiment."
"If Professor Liu hadn't helped with the testing, I wouldn't have known that this material would perform so well."
At this point, Xu Yun made a tactical pause and watched Liu Jingying remain silent for the time being to give the other party time to think.
In Liu Jingying's opinion, these words were meant to be modest, so she did not continue to ask further questions. The next second, she suddenly changed the subject and asked another matter that was related to her.
"I don't know if Professor Xu has time these days. I would like to ask you about the synthesis process of this material." After putting forward his request, he quickly added without waiting for Xu Yun's answer: "If you don't have enough time, If so, we can talk about it later."
Obviously he was afraid of Xu Yun being in trouble.
Photoresist has always been her research field, and this time she took a graduate student on the subject.
Now that Xu Yun has directly developed high-end photoresist, their topic seems to have lost its original meaning.
But if she could ask Xu Yun for technical questions, it would undoubtedly be of great help to her own knowledge and level.
Xu Yun naturally didn't mind communicating with him. Anyway, after the new material issue was completely resolved, he was really not very busy. The basic focus was still on starting classes and participating in teaching work.
With Meng Songyan at the helm, Deepin Technology Company is completely on the right track and there is nothing to worry about.
What's more, Chen Shihe is also helping in the company.
There are no new projects in the laboratory for the time being. The intelligent driving in charge of the artificial intelligence laboratory relies on Benben to believe that it can be completed smoothly.
When his thoughts reached this point, a smile appeared on Xu Yun's face, and he immediately gave Liu Jingying a positive answer.
"No problem at all."
As soon as Liu Jingying finished speaking, several graduate students next to him looked very excited.
"Professor Xu, can we come and observe then?"
"We really enjoyed your class."
"May I?"
They all begged Xu Yun.
As a professor, my favorite students are undoubtedly students who are willing to learn.
Facing the study requests from several graduate students, there was no reason to refuse, so they immediately nodded and agreed.
"Can."
"You guys are lucky. This kind of opportunity is not easy to come across even if you look at other universities." Liu Jingying raised his eyes and looked at the graduate students beside him and said with a smile.
At this point, things are basically coming to an end.
Judging from the test results of material samples by Liu Jingying's research team, it has reached the standard of high-end photoresist.
It is equivalent to completely filling the gap in the domestic high-end photoresist market.
But the only problem is that there are currently no high-end extreme ultraviolet lithography machines in China that cannot produce chip wafers smaller than 5 nanometers.
In this way, the stability of the photoresist cannot be tested, and value cannot be realized in a short period of time.
It's not even useful.
But there is nothing that can be done. After all, overseas fabs have established relatively stable cooperation with Neon's company, and it is absolutely impossible to easily replace new photoresist.
They don’t have the guts to bet on the stability of the new photoresist. If there is a problem during chip precision manufacturing, it will cause very large economic and material losses to the wafer factory.
I finally completed the advanced mission and got this reward, but I really wouldn’t be willing to do anything.
At least let the outside world know about the rise of domestic high-end photoresist.
Even if it is not needed for the time being.
Liu Jingying seemed to have thought of the same thing as Xu Yun, and the next second he took the initiative to ask for advice.
"correct."
"Professor Xu, what are you going to do about the results of this new photoresist semiconductor material?"
"Do you want to announce it to the public?"
"Of course we have to announce the good news, and the sooner the better." Xu Yun finally made the decision and turned to Liu Jingying.
Hearing this sentence, Liu Jingying nodded and said: "Right now, we are frustrated in the semiconductor field. The excellent chips we designed cannot be manufactured. Although it will take time to localize the high-end chip manufacturing industry, it is good to solve the photoresist problem first. This is exciting news." She briefly introduced the current situation in the industry to Xu Yun.
Xu Yun doesn't know much about the semiconductor field, but he still knows the general situation he faces.
Benben will forward global information to him every day.
Without photoresist alone and no supporting high-end chip manufacturing production lines, it is impossible to control chip independence.
Although the development of domestic high-end extreme ultraviolet lithography machines faces many technical difficulties that cannot be overcome, he does not mind participating in research if necessary.
His knowledge of optoelectronics is no less than that of professors and researchers in this field.
Solving the problem of solid-state lidar in the first place is a good illustration.
Besides, he has now accumulated more than 400 points, and with sufficient brain overclocking activation time, there is no problem in completely conquering the high-end extreme ultraviolet lithography machine manufacturing technology and taking it a big step forward, to be conservative.
But this is a major national project after all, and his best field is not optoelectronics.
If you want to participate and have a certain say, you still need to wait for a suitable opportunity.
Xu Yun's thoughts didn't stay here for too long. He told Liu Jingying and the others to go to dinner as soon as possible, and then he went to the dean's office to find Sun Zhenghong and mentioned the matter.
Sun Zhenghong is very aware of Xu Yun's talent in the field of materials, and it can be said that he is eager for Xu Yun to come to the Academy of Materials Engineering.
But after learning that Xu Yun had synthesized a high-end photoresist this time, even though he was somewhat immune, his heart still beat hard twice.
If he hadn't been physically strong, he might have fainted from excitement.
"You guys really surprise me in every possible way. You can develop something that many semiconductor material laboratories have invested a lot of money and manpower to develop so easily."
"OK."
"It's really great."
In the office, Sun Zhenghong stood up from his chair. After reading the test report of the material, he patted Xu Yun on the shoulder and spoke.
There was no hiding the joy on his face during the process.
If someone else came to him and told him that he had synthesized high-end photoresist semiconductor materials, he would be suspicious. At least he would not be as happy as he is now just hearing the news.
The reason is not only that this test report was issued by Liu Jingying, but also that Xu Yun has the ability.
After touching each other for a few seconds, Sun Zhenghong calmed down a little and immediately told Xu Yun about the follow-up.
"I will report on the results of this research immediately. I believe many old guys who study semiconductors will be very happy."
As soon as he finished speaking, he seemed to have thought of something again, and asked again: "You'd better take time to perfect the paper these days, so as not to be smeared by those arrogant guys."
Since we want to announce our achievements in the field of photoresist to the outside world, the paper must be a strong support.
Anyway, the content of the paper is basically based on the synthesis process and data, and it basically does not involve important core parameters. It is not afraid that other companies will secretly infringe the patent and conduct in-depth research.
Besides, without the supporting chip production process, photoresist alone is of no use.
For Xu Yun, the paper was undoubtedly a matter of faith and did not take much time to write.
Naturally, he would not refuse such a casual thing, and he immediately nodded and agreed upon hearing this.
"Don't worry, Dean, I will finish the thesis as soon as possible."
Even in order not to waste time, Xu Yun and Sun Zhenghong briefly chatted for a few words before returning to the Institute of Advanced Mathematics, planning to start writing the paper first.
As for the follow-up matters of the materials, they are all left to Sun Zhenghong.
that's all.
Two or three days passed quickly.
While Xu Yun was busy writing his thesis, Jingzhou University finally announced the good news about the college to the outside world.
It was announced that full professor Xu Yun has successfully synthesized high-end photoresist semiconductor materials in the laboratory of the Academy of Materials Engineering.
And announced the test report of the new photoresist.
Because high-end lithography machines cannot be manufactured, the semiconductor market is controlled by others and everyone is holding their breath.
Netizens in particular were very unhappy.
But since my skills are not as good as others, I have no choice but to swallow my anger.
Nowadays, in the fields of mathematics, lidar, artificial intelligence and other fields, everyone is full of confidence and full of strong pride. However, when the semiconductor-related photolithography chip manufacturing is mentioned, it suddenly feels like an eggplant beaten by frost. There is no longer that lack of confidence.
It is under this circumstance that the good news about photoresist from Kyongshu University is undoubtedly a shot in the arm.
It aroused everyone's passion to a great extent.
At first, when everyone saw that high-end photoresist had been synthesized, they still had some questions.
Unexpectedly, the research on photoresist has progressed so quickly.
According to the previous situation, domestic low-end photoresist has basically achieved coverage and is quite mature.
Mid-range photoresists are also under development.
As a result, we did not wait for the news about the breakthrough of mid-range photoresist, but directly upgraded to high-end photoresist.
And judging from the published test reports, many data are even higher than the high-end photoresist produced by Neon's company.
Such a situation that is beyond common sense will inevitably lead to doubts and make people unable to believe the authenticity of the good news.
Fortunately, this suspicion did not stay in the mind for too long. When everyone saw that the developer was Xu Yun, all doubts immediately dissipated. It seemed that as long as the project handled by Xu Yun, no matter how surprising it was, there would be no problems.
Because this is the experience summarized by history.
Soon the entire Internet was immersed in the joy brought by Xu Yun, and the topic directly dominated the hot search lists of major website platforms.
The most gratifying thing is that Xu Yun has finally begun to enter the field of semiconductor materials.
With the beginning of high-end photoresist, can high-end photolithography machines be far behind? Netizens were extremely excited just by being immersed in this fantasy, and they were discussing intensely in the comment area of the relevant video.
"Aren't we still developing mid-range photoresists? How come we suddenly solved the problem of high-end photoresists?"
"It turns out it's Professor Xu's research result. That's okay."
"Before the popularity of artificial intelligence models has completely passed, Professor Xu has made a big move on semiconductor materials. I still say that you can always trust our Professor Xu."
"My dear, these parameters have already surpassed the high-end photoresist from Neon."
"When will Professor Xu research photolithography machines? If we don't have high-end photolithography machines to develop this kind of photoresist, we won't be able to use it."
"Are you sure that Professor Xu's military exoskeleton armor outstanding youth project has ended this time? Otherwise, there should be no time to study photoresist. I am curious about what happened to this outstanding youth project?"
"Exoskeletons are not unusual in the first place. If there were any results, the official would have announced them to the outside world. Professor Xu probably chose to give up. After all, everyone will stumble at some point."
In the massive comments, many people mentioned the previous outstanding youth project and had some doubts about it.
Although the cycle of the Outstanding Youth Project lasts four years, Xu Yun basically stayed at Jingzhou University to teach during this period, and now he has developed high-end photoresist. It doesn't look like he is working on the Outstanding Youth Project.
Mainly based on the funding project information published by the foundation, it was determined that Xu Yun was researching military exoskeletons.
Everyone is no stranger to exoskeletons, and there is really not much room for improvement through continued research.
Logically speaking, with Xu Yun's level, it should have been completed long ago.
As a result, there is no news yet.
In this case, netizens deduced based on the known information that Xu Yun should have given up on the project.
After all, during the course of the project, it was discovered that the research value was not high, so it was normal to choose to give up and study other things. Otherwise, there might not have been any breakthroughs in high-end photoresist today.
In addition, many people have called for Xu Yun to participate in the research of high-end lithography machines.
As the topic becomes more and more popular, many official organization accounts can be seen posting messages of congratulations.
These include several research institutes under the Academy of Sciences.
Warwick Technology, which is extremely looking forward to the delivery of domestically produced high-end lithography machines, also issued a message to express its gratitude to Xu Yun and Jingzhou University.
It didn't take long for the news to spread overseas, and Xu Yun's name was reported by some newspapers.
But compared to the heat here, the reaction outside was much smaller, and it seemed that they didn't take this situation too seriously at all.
I don’t think it will affect their position in the semiconductor field.
It is mainly just photoresist. No matter how powerful the parameters are, it will not be able to play any role without a high-end photolithography machine.
This is the same as a gun without bullets is worse than a fire stick.
——
As the news spread in the next few days, as neon, which accounts for almost all of the world's high-end photoresist shares, related leading semiconductor material companies also have discussions.
However, most of them are skeptical and believe that it is impossible for Kyungshu University to synthesize high-end photoresist.
It's not that they are blindly confident, mainly because they are at the top of the pyramid in this field and have the qualifications to question it.
The name Xu Yun may not be unfamiliar to you, but he is indeed a globally recognized genius.
But they are more aware of the difficulty of developing high-end photoresist. The entire company does not know how much energy and financial resources it has spent to gain a firm foothold and become the world's most advanced photoresist supplier.
The Chemistry Laboratory of Kyongshu University started from scratch and directly upgraded the specifications of photoresist from low-end to high-end in a short period of time. This is completely impossible under common sense.
"Currently due to insufficient production capacity, we will not be able to continue to provide high-end photoresist to several wafer fabs for the time being."
"But next we will increase production capacity and ensure supply as much as possible."
…
"Thank you again for attending today's press conference. If you have any questions, please feel free to ask."
At the Higashi King Shinetsu Chemical press conference, the current president Kimura Ryohei stood on the stage and talked to the reporters in front of him. As soon as he finished speaking, several reporters asked questions one after another.
After answering a few simple questions, one of the male reporters suddenly stood up and asked a question.
"In recent days, it has been widely rumored that the Huafang Keishu University laboratory has successfully synthesized high-end photoresist. I wonder what Mr. Kimura thinks of this matter. Will this affect Shin-Etsu's share of the high-end photoresist market?"
This statement immediately aroused the curiosity of other reporters, wanting to see how the leading company in the field of high-end photoresist would evaluate it.
When Kimura Ryohei heard this question, a smile appeared on his lips first, and then he commented without taking it seriously.
"This should be the funniest joke I heard today. I don't think they can synthesize high-end photoresist. It can be said that even if they are given a detailed paper, they will never be able to create high-end photoresist."
"Is not it?"
There was contempt and confidence in his words. It was obvious that he did not believe the news was true from the beginning.
This kind of provocative answer also made reporters a little fanatical, and they picked up their cameras to take pictures, knowing that this news would definitely cause discussion in the industry and even the world.
After all, the person Ryohei Kimura is talking about is Xu Yun, a genius scientist who has created many miracles and has a large number of fans. (End of chapter)
