Liu Jingying was still immersed in this joy at the moment, and seeing that there was no change in the expression on Xu Yun's face, she was suddenly ashamed of this calm performance, so she hurriedly calmed down her emotions.

Of course, the discussion on this topic continues, and we are amazed by Xu Yun's talent in the field of material research and development.

"Professor Xu."

"You should have known the purpose of the material you developed, right, and you just want to surprise me when you ask me for testing?"

At this time, Liu Jingying spoke again, and a complicated smile appeared on the corner of her mouth to tell her previous speculation.

High-end photoresist synthesis technology has been monopolized by neon, and they almost occupy most of the high-end photoresist market in the world.

It has become the most indispensable part of chip manufacturing.

Other companies have not stopped researching photoresists, but they can only mix in the low-end market.

It has never been able to set foot in the high-end market.

In addition to Neon's firm dominance of the market, which makes it impossible for other photoresists to enter the supply chain, there is also the difficulty of high-end photoresist production processes.

Because it is used for etching a few nanometer chips, all data needs to be extremely accurate and cannot tolerate any 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, if it takes only a few days to synthesize high-end photoresists, then she must not believe in it and is temporarily skeptical.

In this case, there is only one explanation.

Xu Yun probably started to study photoresist materials very early, and successfully synthesized samples not long ago.

It's not that you're completely ignorant of the purpose of the material.

Listening to all of Liu Jingying's words, Xu Yun didn't expect the other party to make such a guess.

However, it is really difficult to explain in too much detail about the new material synthesis technology rewarded by this mission, and no one will doubt anything if there are achievements created in many fields before.

The thought stayed here, he coughed twice and cleared his throat, and then opened his mouth to talk to Liu Jingying.

"Part of my luck in being able to develop this material is that I synthesized it by accident during my experiments."

"If it weren't for Professor Liu's help in testing, I really didn't know that this material would perform so well."

Speaking of this, Xu Yun came to a tactical pause, watching Liu Jingying remain silent for the time being, leaving time for the other party to think.

In Liu Jingying's opinion, these words belonged to maintaining modesty, so she did not continue to ask questions below, and suddenly changed the topic and asked another thing about herself in the next second.

"I don't know if you have time, Professor Xu, these days, I want to ask you about the synthesis process of this material." After making his request, he didn't wait for Xu Yun to answer, and hurriedly added: "If you don't have a lot of time, you can talk about this later." ”

Obviously afraid of Xu Yun's embarrassment.

The main photoresist has always been her research field, and this time she is still taking graduate students to do the project.

Now that Xu Yun has directly brought out the high-end photoresist, their topic seems to have lost its original meaning.

But if she can ask Xu Yun about technical problems, it will undoubtedly be of great help to her own knowledge and level.

Xu Yun naturally doesn't mind communicating with him, anyway, the matter of new materials is completely solved, and he is really not very busy next, and the basic focus is still on participating in the teaching work at the beginning of the class.

With Meng Songyan at the helm, Deepin Technology is already on the right track and doesn't need to worry about anything.

What's more, Chen Shihe also helped in the company.

There are no new projects in the laboratory for the time being, and the intelligent driving in charge of the artificial intelligence laboratory relies on Benben to believe that it can be successfully completed.

Thinking to this point, Xu Yun had a smile on his face, and immediately gave Liu Jingying an affirmative answer.

"Absolutely."

As soon as the words fell, before Liu Jingying could speak, several graduate students next to her looked very excited.

"That Professor Xu, can we come and sit in on it then?"

"We enjoyed your class very much."

"Is that okay?"

They all begged Xu Yun.

As a professor, my favorite is undoubtedly the students who are willing to learn.

Faced with the study requests of several graduate students, there was no reason to refuse, so he immediately nodded and agreed.

"Yes."

"You guys are lucky, this kind of opportunity is not easy to come across even if you look at other universities." Hearing this, Liu Jingying raised her gaze and looked at the graduate student beside her, and said with a smile.

At this point, it's almost over.

Judging from the test results of material samples by Liu Jingying's research group, it has reached the standard of high-end photoresist.

It is equivalent to completely filling the gap in the domestic high-end photoresist market.

However, the only problem is that there is no extreme ultraviolet high-end lithography machine in China, which cannot manufacture chip wafers smaller than 5 nanometers.

As a result, it is not possible to test the stability of the photoresist, and the value is basically not realized in a short period of time.

It's not even useful.

But this is also a matter of no choice, after all, overseas wafer factories have established a relatively stable cooperation with Neon companies, and it is absolutely impossible to easily replace the new photoresist.

They don't have the guts to gamble on the stability of the new photoresist, and if there is a problem in chip precision manufacturing, it will cause very large economic and material losses to the fab.

It's hard to complete the advanced task to get this reward, and if you don't do anything, you're really unwilling.

At the very least, let the outside world know about the rise of domestic high-end photoresist.

Even if you don't need it yet.

Liu Jingying seemed to think of the same thing as Xu Yun, and took the initiative to ask for opinions in the next second.

"That's right."

"What are you going to do about the results of this new photoresist semiconductor material, Professor Xu?"

"Do you want to make it public?"

"Of course, the good news should be announced, and the sooner the better." Xu Yun finally made a decision, turned his head and said to Liu Jingying.

Hearing this, Liu Jingying nodded and said: "At present, we are frustrated everywhere in the semiconductor field, and the excellent chips designed cannot be manufactured. 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.

There is a stupid person who will forward him global information every day.

If there is no supporting high-end chip manufacturing production line for photoresist alone, it will not be able to master chip independence.

Although the research and development of domestic high-end extreme ultraviolet lithography machine faces a number of technical difficulties that cannot be broken, he does not mind participating in the research if necessary.

He has no less knowledge of optoelectronics than 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, plus enough brain overclocking time, not to mention completely conquering the high-end extreme ultraviolet lithography machine manufacturing technology, there is no problem in pushing it forward.

However, after all, this is a major national project, and his best field is not optoelectronics.

If you want to participate and have a voice, you need to wait for a suitable opportunity.

The thought stayed here Xu Yun didn't stay too long, and explained to Liu Jingying and asked him to go to dinner as soon as possible, so he went to the dean's office to find Sun Zhenghong and mention the matter.

Sun Zhenghong is very aware of Xu Yun's talent in the field of materials, and it can be said that he can't wait for Xu Yun to come to the Academy of Materials Engineering.

But after learning that Xu Yun synthesized a high-end photoresist this time, Rao is immune heart still beat twice without fighting.

If it weren't for the fact that his body was still quite tough, he would probably be so excited that he would faint.

"You kid really surprised me by changing the way, how many semiconductor materials laboratories can't invest a lot of money and manpower to make things that you can develop so easily."

"Okay."

"It's so good."

In the office, Sun Zhenghong got up from his chair, patted Xu Yun's shoulder and spoke after reading the test report of the materials.

The joy on his face was not concealed in the slightest.

If someone else had come up to him and told him that he had synthesized a high-end photoresist semiconductor material, he would have doubted that he wouldn't be as happy as he is now.

The reason is not only that this test report was issued by Liu Jingying, but also believes that Xu Yun has this strength.

After touching the past few seconds, Sun Zhenghong calmed down a little, and even talked about the follow-up to Xu Yun.

"I will report on the results of this research immediately, and I believe that many old guys who study semiconductors will be happy."

As soon as the words fell, he seemed to think of something again, and instructed again: "You'd better take time to perfect your thesis these days, so as to save yourself from being smeared by those arrogant guys." ”

Since it is necessary to announce the results achieved 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 basically does not involve important core parameters, and I am not afraid that other companies will secretly infringe on patents for in-depth research.

In addition, there is no supporting chip production process, and photoresist alone is useless.

The paper is undoubtedly faithful to Xu Yun, and it doesn't take much time to write.

Naturally, he would not refuse such a casual thing, and immediately nodded and agreed when he heard this.

"Don't worry, Dean, I'll finish my thesis as soon as possible."

Even in order not to waste time, Xu Yun and Sun Zhenghong chatted briefly and then returned to the Institute of Advanced Mathematics, planning to start writing the paper first.

As for the follow-up of the materials, all the things will be handed over to Sun Zhenghong.

That's it.

Two or three days passed quickly.

While Xu Yun was busy writing his dissertation, Jingzhou University finally released the good news of the college to the outside world.

It was announced that full professor Xu Yun had successfully synthesized high-end photoresist semiconductor materials in the laboratory of the Academy of Materials Engineering.

And publish the test report of the new photoresist.

Because of the inability to manufacture high-end lithography machines, the semiconductor market is controlled by others, making everyone hold their breath.

Especially netizens are very unhappy.

But his skills are not as good as others, so he has to swallow his anger.

Nowadays, in the fields of mathematics, lidar, artificial intelligence, etc., everyone is full of confidence and full of a strong sense of pride, but when it comes to semiconductor-related lithography machine chip manufacturing, it is suddenly like a frosted eggplant, and there is no longer that lack of confidence.

It is in this context that the good news from Kyungju University on photoresist is undoubtedly a shot in the arm.

It greatly mobilized everyone's passion.

At the beginning, everyone saw that a high-end photoresist was synthesized, and there were still some doubts in their hearts.

I didn't expect the research of photoresist to progress so quickly.

According to the previous situation, the domestic low-end photoresist has basically achieved coverage and is quite mature.

Mid-range photoresists are also under development.

As a result, I didn't wait for the news of the mid-end photoresist to come out, but directly upgraded to high-end photoresist.

And judging from the published test reports, many of the data are even higher than the high-end photoresists produced by Neon companies.

Such an unreasonable situation inevitably leads to suspicion and makes it impossible to believe the authenticity of the good news.

Fortunately, this suspicion did not stay in the mind for too long, and when everyone saw that the developer was Xu Yun, all doubts suddenly dissipated, and it seemed that as long as it was a project handled by Xu Yun, no matter how surprised it was, there could be no problem.

Because this is the experience of history.

Soon, the whole network 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 finally began to enter the field of semiconductor materials.

There is a high-end photoresist at the beginning, so will the high-end lithography machine be far away, netizens are extremely excited just by immersing themselves in this fantasy, and they are discussing fiercely under the relevant video comment area.

"Aren't we still developing mid-range photoresists, why did we suddenly solve the high-end photoresists?"

"It turned out to be Professor Xu's research results, so it's okay."

"The popularity of artificial intelligence models has not completely passed, Professor Xu has put a big move on semiconductor materials, and I still say that you can always trust our Professor Xu."

"I'm obedient, these parameters have surpassed the high-end photoresist on the neon side."

"When did Professor Xu study the lithography machine, and he would not be able to use this photoresist without a high-end lithography machine."

"Is it certain that Professor Xu's military exoskeleton armor project has ended this time, otherwise there should be no time to study photoresist, and I am curious about what happened to this outstanding youth project?"

"Exoskeletons are not unusual, if there were results, the official should have announced them to the outside world a long time ago, it is estimated that Professor Xu chose to give up, after all, anyone has a time when the horse stumbles."

In the massive comments, many people mentioned the previous Outstanding Youth Project, which had some doubts.

Although the Jieqing project cycle is four years, Xu Yun basically stayed at Jingzhou University to teach during this time, and now he has developed a high-end photoresist, which does not look like he is researching the Jieqing project.

Mainly according to the information of the funded projects announced by the foundation, it was determined that Xu Yun was researching military exoskeletons.

Everyone is no stranger to exoskeletons, and there is not much room for improvement in continued research.

It stands to reason that with Xu Yun's level, it should have been completed a long time ago.

As a result, there is no news so far.

In this case, netizens deduced from the known information that Xu Yun should have given up the project.

After all, in the process of carrying out the project, it is found that the research value is not high, and it is normal to choose to give up and study other things, otherwise there may not be a breakthrough in today's high-end photoresist.

In addition, there are many people who call for Xu Yun to participate in the research of high-end lithography machines.

As the topic becomes more and more popular, I can see that many official agency accounts have posted congratulations.

These include several research institutes under the Academy of Sciences.

Huawei Technology, which is looking forward to the delivery of domestic high-end lithography machines, also issued a message to express gratitude to Xu Yun and Jingzhou University.

It didn't take long for the news to spread overseas, and some newspapers reported Xu Yun's name.

But compared to the heat here, the reaction is much smaller, and it seems that this situation is not taken seriously at all.

I don't think it will affect their position in the semiconductor field.

It's mainly just photoresist, no matter how powerful the parameters are, it can't play any role without a high-end lithography machine.

This is the same as the gun without bullets, it is better to burn the stick.

——

With the spread of news in the next few days, neon, which occupies almost all of the world's high-end photoresist shares, has also been discussed by leading companies in related semiconductor materials.

It's just that most of them are skeptical, believing that it is impossible for Gyeongju University to synthesize high-end photoresists.

It's not that they are blindly confident, but they are mainly qualified to question the existence of the pyramid in this field.

Xu Yun's name may not be unfamiliar, but he is indeed a globally recognized genius.

But they know better how difficult it is to develop high-end photoresists, and the whole company doesn't know how much energy and financial resources it takes to gain a foothold and become the world's most advanced photoresist supplier.

The chemistry laboratory of Kyonju University started from scratch and raised the specifications of photoresist from low-end to high-end in a short period of time, which is completely impossible under common sense.

"At present, due to insufficient production capacity, it will not be able to continue to provide high-end photoresist to several fabs for the time being."

"But then we will increase our production capacity and ensure supply as much as possible."

……

"Thank you again for joining us today, and if you have any questions?"

At the press conference of Dongjing Shin-Etsu Chemical, the current chairman Ryohei Kimura stood on the stage and talked to the reporters in front of him.

After answering a few simple questions, one of the male reporters suddenly stood up and asked.

"In recent days, it has been rumored that the laboratory of Huafang Jingzhou University has successfully synthesized high-end photoresists, I wonder what Mr. Kimura thinks about this matter, will this affect Shin-Etsu's share of the high-end photoresist market?"

As soon as this remark came out, it immediately aroused the curiosity of other reporters, wanting to see what it would say as a leading enterprise in the field of high-end photoresist.

When Ryohei Kimura heard this question, a smile first appeared on the corner of his mouth, and then he didn't take it to heart at all.

"This is probably the funniest joke I've heard today, I don't think they can synthesize high-end photoresists, and I can say that even if they give them a detailed paper, they can't make high-end photoresists."

"Isn't it?"

There was contempt and confidence in the words, and it was clear that from the beginning he did not believe that the news was true.

And this kind of provocative answer also made reporters a little fanatical, and they picked up their cameras to shoot, knowing that this news would definitely cause discussion in the industry and even around 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)
