Liu Jingying did not sell Xu Yun's problem, and reached out to take the material sample and explained: "The project we are currently working on is semiconductor material photoresist, but unfortunately the test data of the synthesized photoresist sample is far lower than the quality requirements of the mid-range photoresist. When it comes to the difficulty, the eyebrows are visibly low.

Listening to these words, Xu Yun's mind suddenly appeared his understanding of semiconductor materials.

As an important part of the chip manufacturing process, both lithography and photoresist cannot be done without either.

China has not yet mastered the manufacturing technology of high-end extreme ultraviolet lithography machines, and it is unable to support the huge supply chain required, resulting in the high-end semiconductor field has always been firmly held by overseas.

This makes domestic manufacturers want to produce their own high-end chips, and they can only contact the foundry foundry.

In a passive position in cooperation.

In the past two years, due to the gradual instability of the semiconductor industry, conquering high-end lithography machines has also become a top priority.

But while developing lithography machines, photoresists should also not be overlooked.

Without high-end photoresists, even the most advanced extreme ultraviolet lithography machines cannot produce the most advanced precision chips.

Looking at the world, high-end photoresist technology is in the hands of Neon Company, and basically monopolizes most of the market.

At present, although domestic photoresist has gradually covered the low-end market, it still needs to continue to work hard.

Improving the quality of photoresists to the mid-range is unstoppable.

This topic is not only being studied by many university laboratories, but also by some corporate laboratories.

And just as he was thinking about this, several female graduate students from Liu Jingying next to him suddenly spoke up and said a proposal that she thought was very suitable to solve the current difficulty.

Even though she was still wearing a lab coat, she could tell in her tone that she was excited at the moment.

"It would be great if Professor Xu could participate in our project, and I believe that we will definitely get results in a short period of time."

This proposal was immediately agreed to by the others, but before they could open their mouths to echo and express their support, they were directly interrupted by Liu Jingying's stern voice next to them, and instantly returned to being a good baby.

"How."

"I just ran into a problem, and I want to be lazy?"

"Professor Xu is usually so busy at the Institute for Advanced Study in Mathematics, how can he have time to study our topic."

"How can you do it if you don't learn to grow on your own."

can become a graduate student of Liu Jingying, and he must be very clear about his supervisor's temper.

In this case, knowing that he was going to be blamed, he must have decisively chosen to play dead and remain silent and not say anything.

He stood silently and listened to the training.

Speaking of which, Xu Yun didn't expect Liu Jingying to react so much, and he didn't know what to say next when he was a little embarrassed.

If he is good at what he can, he doesn't mind giving some constructive suggestions to Liu Jingying's project, so that their research progress can be slightly accelerated.

He is not too good at key semiconductor materials, so he can only open his mouth and refuse.

"I don't have much research in the field of semiconductor materials, so I'm afraid it's hard to help you with your project."

Liu Jingying was indifferent to this matter, and replied with a smile on her face: "I believe that we will find a way to solve the bottleneck on our subject, how can we ask you for help with everything." After speaking, he didn't forget to glance at the female graduate students next to him.

Anyway, Xu Yun is not omnipotent, and when he encounters a little problem, he will hug his thighs.

So how to improve the level of researchers.

Xu Yun can't do scientific research alone.

The graduate students also knew that they had made a mistake at this moment, and after reacting, they hurriedly apologized.

"Professor Xu is really embarrassed, we just said it casually without going through our brains."

"I hope you don't mind."

"I should be bothering Professor Liu this time, and I don't know if it will affect the progress of your project." Xu Yun heard the answer of the graduate student next to him, waved his hand, and knew that he was a little unreasonable, and his attitude was very polite.

A new type of unknown material is tested in detail to determine the properties of this material and the direction in which it can be used.

This is not a small amount in terms of workload alone.

What's more, it takes time to wait for data.

If you want to complete it completely, it will take a few days to say the least.

Although Liu Jingying agreed very decisively in this matter, if it really affects the other party's research, she will inevitably feel a little embarrassed.

"Don't worry."

"Anyway, the progress of the project has been stagnant in the past few days, and the testing of new material samples may be able to collide with inspiration."

"I'll contact you when the results are out."

At this time, Liu Jingying's words made Xu Yun dispel his worries, and if he said anything more to this extent, it would really seem a bit pretentious and affect the kind and friendly image in everyone's minds.

"Then please leave it to Professor Liu."

He thanked him again and said no more.

The material samples were handed over to Liu Jingying to complete his purpose, and he didn't stay too long.

Save them from delaying their work.

The next step is basically just to wait patiently.

After coming out of the laboratory where Liu Jingying's research group is located, Xu Yun did not return to the laboratory he used, but temporarily returned to the office of the Institute for Advanced Study of Mathematics in the Department of Mathematics.

The matter of major new materials cannot be progressed at present, and whether it is published externally or written for publication, it is necessary to obtain detailed test data results as support.

In the few days he was waiting for the results, he planned to go to the Institute of Physics and the Institute of Planning to hold open classes first.

Complete the invitation from Xu Chongxing and the Planning Institute.

If he has enough time, he also wants to stop by the Academy of Materials Engineering to give a few lectures.

The right should be thanks to Yoo Kyung-young.

Time is something that cannot be seen or touched, but it is the easiest thing to lose, and Xu Yun's life has become regular again in April.

I became an ordinary college professor again.

The public classes he held in the School of Physical Sciences have become popular and have been sought after by students in the two colleges.

Even the number of participants in the lecture has a kind of record-breaking meaning.

This also makes other colleges even more envious.

Later, a hot topic appeared on the school's Internet, and everyone left messages to the dean and vice dean of their own college, hoping to let Xu Yun give a lecture from his own college.

Xu Yun's public lectures are not all mathematics, and he talks about optics-related issues when he is in the Institute of Physics, while the Institute of Planning focuses on artificial intelligence models that have been widely discussed recently.

not only directly quoted stupidity to the class, but also talked about the knowledge of deep learning model algorithms.

It can be said that all of them are hard currency and do not contain any moisture.

Even if you listen to the first half of the section, it is a good improvement to your own strength.

If everyone was attracted by Xu Yun's personality charm at the beginning, then they really wanted to learn something later.

After all, although Xu Yun's lecture style is not much different from that of other professors, it is easy for people to understand and understand, and even combine the knowledge they have learned to integrate and use it flexibly.

This is something that cannot be achieved by normal class learning.

……

……

"The clumsy logic is getting more and more sophisticated, and the changes in all aspects can be seen through the naked eye."

"I'm afraid it won't take long to upgrade to version 3.0."

April 5, 2020, Kyonju University, Independent Professor's Office, Institute for Advanced Study in Mathematics.

At around half past twelve in the afternoon, Xu Yun sat in a chair, his eyes lingering on the social software dialog box on the computer screen.

Looking back on this period of time and clumsy daily communication, the growth trajectory can be clearly and intuitively seen from the answers.

Thinking that Ben Ben will be able to upgrade to version 3.0 soon, I am naturally very happy and excited.

After reaching version 2.0, Benben has surpassed the world's most advanced chatbots in dialogue Q&A, and to a certain extent, it can help humans solve problems encountered in daily life.

And after moving on to the next version, he speculated that the area that Clumsy could radiate into would be even larger.

And it can call powerful computing power to really deal with problems and become the best intelligent assistant for human beings.

The most intuitive benefit is that the company's AI lab will become easier to research on intelligent driving.

During this time, he had to communicate with Ben Ben almost every day, in addition to ensuring that he had a clear control over Ben Ben's ability at any time, he also wanted to constantly discover Ben Ben's performance in other scenes.

In short, he was not disappointed in any way.

Just as he was immersed in it, he heard the sound of shoes on the floor.

At the same time as the frequency regularity, the sound is getting closer and closer.

He realized something in the next second, and quickly raised his gaze to look at the office door.

Until the familiar figure came into view, he immediately stood up from his chair and stepped over to meet him.

Today's sunshine is better, Chen Shihe is wearing a round collar long-sleeved lace shirt and a tea green pleated skirt, and the black short and medium hair gathered around the neck sets off the light makeup on his face, which looks particularly temperamental.

Although he has been married for a while, he does not see any signs of fortune.

Even Xu Yun felt that even if Chen Shihe gave birth to a child in the future, it would not have any impact on his figure.

On the contrary, there will be more maternal brilliance.

Noticing the lunch box in Chen Shihe's hand, he hurriedly reached out and took it.

His eyes were full of pampering.

"Why did you go so far to deliver food to me, the cafeteria of our Beijing University still tastes pretty good."

With a smile on the corner of his mouth, he said this, and temporarily put the lunch box on the solid wood desk next to him.

If he doesn't have anything important, he basically spends lunch in the school cafeteria at noon.

Will only go back in the evening.

However, Chen Shihe often drives over to deliver food.

was seen twice by Tang Yanshan and Qin Xiangxin, which can be said to be very envious and praised them for their little couple.

"You forgot that I also stayed at Beijing University for several years, and I don't know if the food in the cafeteria is good or not." Chen Shihe said as he walked straight and slender legs to the table and stopped, and took the initiative to open the lunch box and take out the food inside: "These are a few dishes that our mother made at noon, and I specially asked me to send them to you." ”

"Why don't you come over and eat it while it's hot."

After speaking, he handed the chopsticks to Xu Yun.

Looking at this scene, Xu Yun dared to hesitate, with a unique clear and stupid smile on his face, he hurriedly took the chopsticks and sat down.

He is expected by the outside world to have the aura of countless geniuses, perhaps at this time he is more like a sunny boy in his twenties.

Chen Shihe sat next to him and watched Xu Yun eat, and after a while, after noticing the content displayed on the screen out of the corner of his eye, he couldn't help but open his mouth to provoke a new topic.

"Were you just talking to Clumsy?"

"yes."

Xu Yun chewed the food, and his voice was a little slurred.

"Judging from the test, it shouldn't take long for Benben to iteratively upgrade to version 3.0, and then the features will become more powerful."

"Ben Ben is really powerful, and Mr. Meng also has a plan to connect Ben Ben into the company to help with all aspects of auxiliary operation to reduce pressure." After listening to Xu Yun's words, Chen Shihe thought about the company's affairs and replied: "Everyone is looking forward to Ben Ben being able to grow into the intelligent brain in science fiction movies." ”

"Absolutely." Xu Yun turned his head and grinned.

First of all, the betrayal of human beings by the brain in science fiction movies will never happen in the real world.

It is impossible for the brain to give birth to the so-called independent consciousness, but to imitate the way of thinking and logic of human beings after learning by itself.

What's more, he has the supreme authority of stupidity.

But if Ben Ben really grows into a so-called intelligent brain in the future, with quantum computers as hardware support, then the significance for the development of human civilization will be very huge.

In addition to completing large-scale projects more efficiently, all kinds of scientific and technological knowledge will usher in an explosion.

Let human civilization enter the era of the big bang of science and technology.

Before Xu Yun could make a move after eating, Chen Shihe took the first step to pack up the lunch box.

Just as he was about to help, his phone on the table suddenly rang.

Professor Liu's incoming call message is displayed on the screen.

"Professor Liu."

Xu Yun's face suddenly overjoyed when he saw the remarks information, and he immediately thought of something.

It has been a few days since the samples of new materials were handed over to Liu Jingying for testing.

Although he never asked, he must have thought in his heart that the sooner he saw the results, the better.

At the moment, Liu Jingying suddenly called, which can only mean that the results of the testing of the materials have appeared, and in this case, he quickly picked up his mobile phone without any hesitation.

Although the conversation between the two of them was only a few short sentences, the news they got was enough to make Xu Yun ecstatic.

On the phone, Liu Jingying said that in addition to the test results, the use of the material was basically determined.

Let him go to the lab as soon as possible.

The news was more of a surprise than he had anticipated.

In front of Chen Shihe, Xu Yun naturally did not hide the joy on his face, and this also made Chen Shihe quite curious.

She re-covered the lunch box and looked at Xu Yun, and subconsciously asked.

"What happened to make you so happy?"

"There are test results for a newly synthesized material before, and I want to go to the laboratory of the Academy of Materials Engineering immediately." Xu Yun answered directly and truthfully, and did not hide anything from Chen Shihe.

Chen Shihe has always been extremely supportive of Xu Yun's work, and he will definitely not lag behind at this time.

"Then you can hurry over, and I'll drive back by myself later." Picking up the lunch box on the table, he smiled.

"I'll try to go back early in the evening."

Xu Yun knew Chen Shihe's character, so naturally he would not twist at such a time.

In response, he was the first to leave the office.

……

Xu Yun did not have any delay on the way, and went straight to the laboratory after successfully arriving at the Academy of Materials Engineering Sciences.

Ms. Yoo and several of her graduate students had apparently not eaten yet, and when he entered, he could see that they were still busy at their workbenches.

Of course, he didn't care about this at this time, and immediately shouted before and after.

"Professor Liu."

"What were the results of that material sample?"

Everyone in the laboratory heard the familiar voice, and immediately stopped their movements for a while and turned around.

Although several of them were still wearing lab coats, they could vaguely see the joy on their faces.

"Professor Xu."

"You gave our research group a big surprise this time!"

Suddenly hearing Liu Jingying's words, Xu Yun seemed a little confused, and his thoughts suddenly became active.

"Surprise?"

These two words were whispered in his mouth.

And just as he was thinking about some surprise, he saw one of the graduate students next to him take two steps towards him, and when he came to him, he leaned down sharply, almost bending his waist to ninety degrees.

"I misunderstood you, Professor Xu, and I apologize again for my previous misunderstanding of you."

"I'm sorry."

Xu Yun looked at the other party's performance in a daze, if he was just a little confused just now, then now his mind is full of question marks and feels strange.

secretly complained in her heart that Liu Jingying and her graduate students learned to be riddlers.

Fortunately, his doubts didn't last long, and then he listened to the graduate student in front of him continue.

"Professor Xu."

"It turns out that you have already developed a new type of photoresist."

"Photoresist?"

After hearing this, Xu Yun keenly caught this keyword, blurted out and repeated the sentence after the other party's words.

In the next second, he realized something, and immediately raised his eyes to look at Liu Jingying for confirmation.

"Professor Liu."

"You're saying that my sample of the material can be used as a photoresist?"

At this time, Liu Jingying will not sell Guanzi, and then briefly talked about the situation in the past few days.

It turned out that when Liu Jingying got the material sample for preliminary testing, she found that the sample was not only similar to the photoresist she was developing, but also the data obtained was very similar to the specified range of the photoresist value.

With such an astonishing discovery, she thought that Xu Yun was probably developing a new photoresist.

Because her topic happened to be in this field, I asked her to conduct a comprehensive test.

In the end, she completely walked through the material sample according to the photoresist test process.

The data I got scared everyone.

The photoresist developed by Xu Yun not only surpassed the ranks of low-to-mid-end and high-end photoresists, but also performed better than the data released by the photoresist company on the neon side.

This shows that the domestic photoresist is likely to achieve corner overtaking.

"According to the test results, the photoresist you developed fully meets the standards of high-end photoresist in terms of contrast, sensitivity, adhesion, corrosion resistance, purity and other indicators."

"This is a major scientific research achievement in semiconductor materials."

When talking about this material sample, even if Liu Jingying is forty years old, she can't control her mood at the moment in front of Xu Yun.

Although it was not long before Xu Yun entered the laboratory experiment, he successfully developed a high-end photoresist with strong test results, which is really shocking. It's just that recalling Xu Yun's previous research and development of shaped fluorocarbon polymer materials and solid-state batteries, it seems that everything is so reasonable and normal.

At this moment, Xu Yun was quite calm, in fact, he had a guess when he was fusing the materials.

Now that I have confirmed that the reward for the advanced task is photoresist material, I suddenly feel a sense of relief.
