Liu Jingying did not give in to Xu Yun's question. She reached out to take the bottle of material sample and explained: "The topic we are currently working on is semiconductor material photoresist. Unfortunately, the test data of the synthesized photoresist sample is far lower than Quality requirements for mid-range photoresist." When talking about the difficulty, the frown can be seen with the naked eye.
After hearing these words, Xu Yun's knowledge of semiconductor materials suddenly came to mind.
As an important part of the chip manufacturing process, photolithography machines and photoresists cannot function without either one.
China has not yet mastered the manufacturing technology of high-end extreme ultraviolet lithography machines, and cannot support the huge supply chain required. As a result, the high-end semiconductor field has always been firmly controlled by overseas countries.
This makes domestic manufacturers who want to produce their own high-end chips have no choice but to contact foundries.
Being in a passive position in cooperation.
In the past two years, as the situation in the semiconductor industry has become increasingly unstable, conquering high-end lithography machines has become a top priority.
But while developing photolithography machines, photoresist cannot be ignored.
Without high-end photoresist, even the most advanced extreme ultraviolet lithography machine cannot produce the most advanced precision chips.
Looking at the world, high-end photoresist technology is in the hands of Neon Company, and it basically monopolizes most of the market.
Although domestic photoresists are gradually covering the low-end market, efforts still need to continue.
It is unstoppable to improve the quality of photoresist and move towards the mid-range.
Not only are many university laboratories studying this topic, some corporate laboratories are also doing this.
While he was thinking about this in his mind, several female graduate students beside Liu Jingying suddenly spoke up and made a proposal that she thought was very suitable to solve the current difficulties.
Even though she was still wearing a lab coat, she could hear her excitement at the moment from her tone.
"It would be great if Professor Xu could participate in our project. I believe we can get results in a short time."
This proposal was immediately agreed to by others, but before they could express their support, they were directly interrupted by the stern voice of Liu Jingying next to them, and they instantly returned to being good babies.
"how."
"You just encountered some difficulties and you want to be lazy?"
"Professor Xu is usually so busy at the Institute for Advanced 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?"
To become Liu Jingying's graduate student, he must have a very clear understanding of his mentor's temper.
In this situation, if you knew you were going to be blamed, you would definitely choose to play dead and remain silent and say nothing.
Just stood there silently and listened to the training.
Speaking of which, Xu Yun didn't expect Liu Jingying to react so strongly. He was a little embarrassed and didn't know what to say next.
If it was something he was good at, he wouldn't mind giving some constructive suggestions to Liu Jingying's project, so that their research progress could be slightly accelerated.
He wasn't very good at key semiconductor materials, so he could only politely refuse.
"I don't have much research in the field of semiconductor materials, so I'm afraid it will be difficult to help you with your project."
Liu Jingying responded calmly to this matter, with a smile on her face and replied: "I believe we will find a way to solve the bottleneck of our project. How can we ask you to help with everything." After saying this, he did not forget to glance at it. The female graduate students next to him glanced at each other.
In any case, Xu Yun is not omnipotent. If he encounters any problems, he will hug his thighs.
So how to improve the level of researchers.
Xu Yun alone cannot do scientific research alone.
The graduate students also knew that their words were wrong at this moment, and after realizing it, they quickly apologized.
"Professor Xu, I'm really sorry. We just said it casually without thinking about it."
"I hope you don't mind."
"I should be the one bothering Professor Liu this time. I don't know if it will affect the progress of your project." Xu Yun heard the reply from the graduate student next to him, waved his hands and was very polite, knowing that he was a bit unreasonable.
Detailed testing of a new, unknown material to determine its properties and possible uses.
It’s not a small amount in terms of workload alone.
Besides, waiting for data also takes time.
If you want to fully complete it, it will take a few days at least.
Although Liu Jingying agreed decisively on this matter, if it really affected the other party's research, he would inevitably feel a little embarrassed.
"Do not worry."
"Anyway, the progress of the project has been stagnant these days. Testing new material samples may lead to inspiration."
"I will contact you when the results come out."
At this time, Liu Jingying's words made Xu Yun put away his worries. If he said anything more after talking to this extent, it would really seem a bit pretentious and affect the kind and friendly image in everyone's mind.
"Then please leave it to Professor Liu."
I thanked him again and didn't mention it any more.
The material samples were handed over to Liu Jingying to fulfill his purpose, and he immediately stopped staying too much.
So as not to delay their work.
Basically, you just need to wait patiently.
After coming out of the laboratory where Liu Jingying's research group was located, Xu Yun did not return to the laboratory he used, but temporarily returned to the office of the Institute for Advanced Study in Mathematics, Department of Mathematics.
The matter of major new materials cannot progress at the moment. Whether it is announced to the public or published, detailed test data results must be obtained first as support.
While waiting for the results in the past few days, he planned to give open classes at the Academy of Physics and the Academy of Design.
Complete the invitations from Xu Chongxing and the Planning Institute.
If he had enough time, he would also like to stop by the School of Materials Engineering to give a few lectures.
Quan should be grateful to Liu Jingying.
Time is something that is invisible and intangible but is easily lost. In April, Xu Yun's life became regular again.
Become an ordinary college professor again.
The public classes he held in the School of Physics and Engineering successively became popular and were sought after by students in both schools.
Even the number of people participating in the lecture seemed to have broken a record.
This also makes other colleges even more envious.
Later, a hot topic appeared on the school website. Everyone left messages to the dean and deputy dean of their college, hoping that Xu Yun could give lectures from his college.
The main reason is that Xu Yun's open classes are not all about mathematics. When he was in the Institute of Physics, he talked about optics-related issues, while in the Institute of Engineering, he focused on artificial intelligence models, which have been widely discussed recently.
Not only did he directly quote Benben into the class, but he also talked about deep learning model algorithms.
It can be said that it is all hard currency and does not contain any moisture.
Even listening to the first half of the verse is a good improvement to one's own strength.
If everyone was attracted by Xu Yun's personality charm at first, then they really wanted to learn something later.
After all, although Xu Yun's teaching method is not much different from other professors, it is easy for people to understand and even integrate and use it flexibly based on the knowledge he has learned.
This is something that cannot be achieved by normal class study.
…
…
"Benben's logic is becoming more and more rigorous, and all changes can be seen with the naked eye."
"I'm afraid it won't take too long to upgrade to version 3.0."
April 5, 2020, Kyongshu University, Office of Independent Professors, Institute for Advanced Study of Mathematics.
At about 12:30 noon, Xu Yun sat on a chair, his eyes fixed on the social software dialog box on the computer screen.
Looking back on the daily communication with Benben during this period, the growth trajectory can be clearly and intuitively seen from the answers.
Thinking that Benben will soon be upgraded to version 3.0, I am naturally very happy and excited.
After Benben reached version 2.0, it has surpassed the world's most advanced chatbots in conversation and question answering, and to a certain extent, it can help humans solve problems encountered in daily life.
After entering the next version, he speculated that the areas that Benben can radiate will be even larger.
And it can use powerful computing power to truly solve problems and become the best intelligent assistant for mankind.
The most intuitive benefit is that the company’s artificial intelligence laboratory’s research on intelligent driving will become easier and easier.
During this period, he communicated with Benben almost every day. In addition to ensuring that he had clear control over Benben's abilities at all times, he also wanted to constantly explore Benben's performance in other scenes.
In short, he was not disappointed in any way.
Just as he was immersed in it, the sound of shoes hitting the floor suddenly came to his ears.
While the frequencies are regular, the sounds are getting closer and closer.
He realized something in the next second, and quickly raised his gaze to look at the door of the office.
When a familiar figure came into view, he immediately stood up from his chair and walked towards him.
The sun is relatively bright today. Chen Shihe is wearing a round collar, long-sleeved lace shirt and a tea-green pleated skirt. The short and medium-length black hair gathered around her neck looks particularly elegant with the light makeup on her face.
Although she has been married for some time, she does not see any signs of gaining weight.
Even Xu Yun felt that even if Chen Shihe gave birth to a child in the future, it would not have any impact on her figure.
On the contrary, there will be more maternal brilliance.
Noticing the lunch box in Chen Shihe's hand, he quickly reached out and took it.
His eyes were full of doting.
"Why do you come so far to deliver food to me? Our cafeteria at Beijing University tastes pretty good."
After saying this with a smile on his face, he temporarily placed the lunch box on the solid wood desk next to him.
If he has nothing urgent to do, he usually eats lunch in the school cafeteria at noon.
Will go back at night.
However, Chen Shihe would often drive over to deliver meals.
Twice he was seen by Tang Yanshan and Qin Xiangxin, who expressed his envy and praised the young couple.
"You have forgotten that I have been at Beijing University for several years. I don't know whether the food in the cafeteria is delicious or not." Chen Shihe said as he walked to the table with his straight and slender legs, and took the initiative to open the lunch box and take out the food inside. Meal: "These are some dishes that my mother made for lunch. I specially asked me to bring them to you."
"Why don't you come over and eat it while it's hot?"
After saying that, he handed the chopsticks to Xu Yun.
Seeing this scene, Xu Yun didn't dare to hesitate. With a unique clear and silly smile on his face, he quickly took the chopsticks and sat down.
With high hopes from the outside world and countless talents, perhaps at this time he is more like a sunny boy in his twenties.
Chen Shihe sat aside and watched Xu Yun eat. Not long after he noticed the content displayed on the screen out of the corner of his eye, he couldn't help but raise a new topic.
"Were you chatting with Benben just now?"
"yes."
Xu Yun's voice was a little unclear as he chewed the food.
"Judging from the tests, Benben will be iteratively upgraded to version 3.0 soon, and its functions will become more powerful by then."
"Benben is indeed very powerful. Mr. Meng also has plans to connect Benben to the company to help with various auxiliary operations to reduce pressure." After listening to Xu Yun's words, Chen Shihe thought of the company's affairs and replied: "Everyone is looking forward to Benben's growth. To the intelligent brain from a science fiction movie.”
"It's definitely possible." Xu Yun turned his head and grinned.
First of all, the intelligence betraying humans in science fiction movies will never happen in the real world.
It is impossible for the intelligent brain to give birth to the so-called independent consciousness. It can only imitate human thinking methods and logic after learning.
What's more, he has the highest authority over Benben.
But if Benben really develops into a so-called intelligent brain in the future, with quantum computers as hardware support, the significance to the development of human civilization will be 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 technological explosion.
After finishing the meal, Chen Shihe packed up the lunch box before Xu Yun could take action.
Just when he wanted to help, the cell phone on the table suddenly rang.
Professor Liu's call information was displayed on the screen.
"Professor Liu."
Xu Yun's face suddenly became happy when he saw the note information, and he immediately thought of something.
It has been some time since the new material samples were handed over to Liu Jingying for testing.
Although he never pressed me, he must have thought that the sooner he could see the results, the better.
Now Liu Jingying suddenly called, which could only mean that the test results of the material had appeared. In this case, he quickly picked up the phone and answered the call without any hesitation.
Although the conversation between the two of them only lasted a few words, the news they got was enough to make Xu Yun ecstatic.
During the phone call, Liu Jingying said that in addition to obtaining test results, the use of the materials has also been basically determined.
Have him go to the lab as soon as possible.
This news was more surprising than he had expected.
Naturally, Xu Yun would not hide the joy on his face in front of Chen Shihe, which also made Chen Shihe quite curious.
She covered the lunch box again, looked at Xu Yun, and asked subconsciously.
"What happened to make you so happy?"
"There are test results for a newly synthesized material. I want to go to the laboratory at the Academy of Materials Engineering immediately." Xu Yun answered 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 hold him back at this time.
"Then go over there quickly. I'll just drive back later." He picked up the lunch box on the table and said with a smile.
"I'll try to go back as early as possible in the evening."
Xu Yun knew Chen Shihe's character, so naturally he would not be shy at this time.
He responded and left the office first.
…
Xu Yun didn't have any delays on the way. After successfully arriving at the Academy of Materials Engineering, he went straight to the laboratory.
Liu Jingying and several of her graduate students had obviously not eaten yet. When he entered, he could see that they were still busy at the workbench.
Of course, he didn't care about this at this time, and immediately started shouting as he approached.
"Professor Liu."
“What were the test results of that material sample?”
When everyone in the laboratory heard a familiar voice, they immediately stopped what they were doing and turned around.
Although several people were still wearing lab coats, one could vaguely see the joy on their faces.
"Professor Xu."
"You gave our research team a big surprise this time!"
Suddenly hearing Liu Jingying's words, Xu Yun seemed a little confused, and his thoughts suddenly became active.
"surprise?"
He whispered these two words softly.
Just when he was thinking about the surprise, he saw one of the graduate students next to him taking two steps towards him. When he came to him, he suddenly leaned over and bent his waist almost to 90 degrees.
"I misunderstood you, Professor Xu. I apologize again for my previous misunderstanding."
"sorry."
Xu Yun stared at the other party's performance. If he was just a little confused just now, now his mind is full of question marks and feels strange.
Secretly complaining about Liu Jingying and her graduate students, when did they learn to be the Riddler.
Fortunately, his doubts did not last long, and he heard the graduate student in front of him continue talking.
"Professor Xu."
"It turns out that you have developed a new type of photoresist a long time ago."
"Photoresist?"
After hearing this sentence, Xu Yun keenly caught the key word and blurted out and repeated the sentence after the other person's words.
The next second he suddenly realized something, and immediately raised his gaze to look at Liu Jingying for confirmation.
"Professor Liu."
"You are saying that my material sample can be used as photoresist?"
At this time, Liu Jingying could not show off, and then briefly talked about the situation in the past few days.
It turned out that when Liu Jingying received the material sample for preliminary testing, she found that in addition to being similar to the photoresist she was developing, the data obtained also closely resembled the numerical range specified for the photoresist.
With such an amazing discovery, she thought that Xu Yun was probably developing a new photoresist.
Because her subject happened to be in this field, I asked her to conduct a comprehensive test.
Finally, she went through the material sample completely according to the photoresist testing process.
The data obtained shocked everyone.
The photoresist developed by Xu Yun has not only surpassed the low-end and mid-range and entered the ranks of high-end photoresists, but its numerical performance in all aspects is even higher than the data published by Neon's photoresist company.
This shows that domestic photoresist is likely to achieve overtaking in corners.
"According to the test results, the photoresist you developed fully meets the standards of high-end photoresists in terms of contrast sensitivity, adhesion, and resist purity."
"This is a major scientific research achievement on semiconductor materials."
When talking about this material sample, even though Liu Jingying was forty years old, she couldn't control her mood in front of Xu Yun.
Although it is extremely shocking to think that Xu Yun successfully developed a high-end photoresist with strong test results not long after entering the laboratory experiment. But recalling Xu Yun's previous research and development of shaping fluorocarbon polymer materials and solid-state batteries, everything seems so reasonable and normal.
At this moment, Xu Yun was still calm. In fact, he had some guesses when he was fusing the materials.
Now that it was confirmed that the reward for the advanced mission was photoresist material, I suddenly felt a sense of relief.
