The Red Era, the Opening University Speech

Chapter 88 I hope everyone will not expose Li Mu (4K please subscribe)
When these experts saw the single crystal furnace in the laboratory and the numbers on it, they all showed surprise reactions.

But before they could ask, they were attracted by the heated discussion between Huang Xinhua and the other two.

As more and more people came, it seemed a bit crowded for eleven or twelve people in the laboratory.

Liu Ze and Wang Yang quickly went to find stools, prepared hot water, and moved some unimportant equipment away, turning the laboratory into a small meeting place.

Li Mu originally wanted to go out, but after listening to the opinions of a group of professors, many of their ideas coincided with the production of photoresist in the materials.

"If they were given some time, I could have developed photoresist without them!" Li Mu couldn't help but marvel at the wisdom of his ancestors.

If we hadn't come from later generations and known how powerful these ancestors were, who would have thought that they, without even a photolithography machine, could overcome difficulties and make integrated circuits under such circumstances?

……

The discussion lasted all afternoon.

Later on, there were more and more people, and we could only find two empty classrooms to accommodate them.

When it was almost time for dinner, the professors and experts were still reluctant to leave.

It was only when Qian Shuyan came over to greet them that everyone stood up and prepared to go to the cafeteria of Beijing Institute of Technology for a quick meal.

A professor from Gusu was leaving, looking at the clay photolithography machine, and turned to ask Li Mu:
"Student Li is really creative. Otherwise, who would have thought that this lithography machine could be made with the existing conditions? When we get back to Gusu, I will ask the Gusu Research Institute to build one as well."

After hearing this, the professors remembered that Li Mu, for whom they came, had no sense of existence the whole afternoon.

"Haha, you're right. Once we have a lithography machine, maybe we can even surpass the Semiconductor Research Institute under the Chinese Academy of Sciences." An expert joked.

Everyone burst into laughter.

But if one thinks about it carefully, it is indeed possible.

Although the Semiconductor Research Institute is full of talented people, it cannot compare to the great genius at Beijing Institute of Technology!

Maybe they are just getting started now and are still stuck on the photolithography machine stage.

Everyone chatted and laughed, and went to the cafeteria one after another to prepare for their meal.

Although Li Mu was hungry, he still chose to stay quietly.

Qian Shuyan was taking care of a group of foreign experts and professors and did not notice Li Mu.

However, Huang Xinhua was always paying attention. When he saw Li Mu staying, he said hello to a few professors and walked back to the laboratory.

"Why don't you go eat?" Huang Xinhua looked at Li Mu, who was in deep thought, and was slightly puzzled. He then said, "Everyone has his own specialty. It doesn't matter if you can't think of it."

Thinking that Li Mu hadn't said a word the whole afternoon, Huang Xinhua thought that Li Mu was hit.

After all, he had often come up with constructive suggestions in his previous research.

Li Mu smiled and said, "Professor Huang, you misunderstood. I just felt that I gained a lot from listening to the discussions of the experts and professors today, so I wanted to take a pen and write them down first."

"You go eat first, I'll be there soon."

Huang Xinhua was relieved and said, "Well, that's good."

"Don't be too late."

Huang Xinhua left after giving his final instructions.

After seeing that everyone had left, Li Mu took out his notes and first wrote down the correct ideas he had heard today, and then briefly extended them a little further.

Of course, even this little bit can reduce many unnecessary attempts in the entire research.

Experiments that know the principles are actually about debugging until the correct data is found.

However, he can only do this much at best. If he writes more, it will no longer be within the scope of his knowledge as perceived by others.

After Li Mu finished writing, he was about to close his notebook and leave when a voice suddenly sounded behind him:
"The main chain and side chain of the photosensitive resin contain chromophore groups... I didn't realize that you, Li Mu, also know about functional polymer materials."

Li Mu was shocked when he heard this. He was so focused that he didn't even notice someone was standing behind him.

Fortunately, he didn’t write anything beyond the syllabus!

"I just listened to many professors and experts' proposals today and I am just repeating what they have said." Li Mu pretended to be calm and turned around. It turned out to be Xu Qing.

"You remembered it just by listening to it once?" Xu Qing was a little surprised.

There were so many professors, talking to each other, and when the debate was intense, it was noisier than a market. It was amazing that Li Mu could remember it all.

The most important thing is that Li Mu can not only remember, but also understand, and then summarize.

This ability cannot be described even with the word genius.

Li Mu looked at the shocked Xu Qing and said, "No matter how much you memorize, it's just dead knowledge. Without understanding, you can't use it."

Hearing this, Xu Qing's eyes flashed with a hint of desire, and he said, "How about... you copy a copy of your notes for me?"

"Both of my teachers are experts in polymer materials and engineering. Although I can't compare to them, I should know a little more about this than you do."

In his last words, Xu Qing was obviously being modest.

So many experts and professors came today, most of them came alone.

The fact that Gu Ming and Lu Qian brought Xu Qing here alone is enough to prove her talent and ability.

If Xu Qing could find the direction from the hints in his notes, he could save himself the trouble of telling those experts and professors directly and making a scene again.

"Of course no problem, we can learn from each other." Li Mu decisively handed the notes to Xu Qing.

Xu Qing didn't expect Li Mu to agree so readily. He smiled and said, "Thank you, Li Mu."

After saying that, Xu Qing left happily with his notes.

Li Mu smiled and was very satisfied with his plan.

"Even if it doesn't work, I will take the initiative to say it out." Li Mu thought as he left the laboratory.

……

After eating in the canteen, I returned to the dormitory.

General Zhao was doing push-ups in the dormitory to exercise his physical fitness. Li Mu greeted him and sat down at the table.

I sorted out my current research ideas: "If the problem of photoresist is solved, the photolithography process can be realized in as fast as half a month."

“When the time comes, thin film deposition, etching and ion implantation processes will follow.”

"If I take it step by step and give you ideas gradually, I should be able to develop an integrated circuit in half a year at most, or at least three months."

"It's just a large-scale integrated circuit. I'm afraid it's not that easy to handle!"

Li Mu looked at the development history of integrated circuits in Xia Country and found it a little tricky.

国内第一块集成电路，在64年由国科院下属的半导体研究所研制而出，是一块具有6只晶体管、7个电阻、6个电容共19个元件的固体电路样品。

Prior to this, the research team had also conducted research on ultra-small silicon planar high-speed switching transistors and high-frequency transistors in the research of silicon planar process transistors.

It was not until 64 that further improvements were made and the size of silicon planar transistors was reduced to the size of sesame seeds, and the silicon planar transistor was considered a true success.

Li Mu thought to himself, "I developed the silicon planar transistor ahead of time, which greatly shortened the process."

"The success of small-scale integrated circuits is only a matter of time, and the next step is large-scale integration." "Device packaging materials, diffusion furnaces, pressure welding machines, vacuum coating equipment... so many equipments must be made!"

"But these are mostly things needed for industrialization, so we can put them aside for now."

Li Mu first found the design drawings of the large-scale integrated circuit, and after hesitating for a moment, he casually wrote down some design ideas and principles on the manuscript paper.

The design of large-scale integrated circuits is not like the single crystal furnaces and ultra-thin diamond wheel cutting machines of the past.

This kind of high-tech stuff is complex and delicate.

Only those that integrate 1000 to 99999 components can be called large integrated circuits.

The complexity of this thing is not something that Li Mu can get away with by just writing a dozen pages of manuscript paper.

At least several hundred pages would be needed to make it seem reasonable.

……

While Li Mu was studying the follow-up technology of integrated circuits, the professors and experts were obviously still interested in talking and returned to the laboratory after dinner.

While listening, Xu Qing took out his notes. Seeing that Li Mu had not come over yet, he helped him take notes first.

But when she turned to the end, she suddenly found something wrong:
"It says here that photoresist has the properties of photo-crosslinking and photo-decomposition reactions, but I don't have any impression of that at all."

"Photocrosslinking allows solvent development so that the photosensitive polymer is retained, while the unexposed polymer is dissolved."

"When the photodecomposition allows the solvent to develop, the unexposed parts are retained, while the exposed parts are decomposed into soluble substances and dissolved."

"In this way, it is possible to produce photoresist with macro structures in the millimeter range!"

"Xu Qing, Xu Qing, why are you daydreaming?" Gu Ming turned his head and saw Xu Qing holding a notebook. He was quite happy at first, thinking that she was taking notes seriously.

But upon closer inspection, he discovered that Xu Qing's eyes were dull and he was not paying attention to the lecture at all.

Xu Qing suddenly came back to his senses and said, "Teacher, I'm not distracted. I have a solution, I have a solution!"

Xu Qing's excited voice attracted the attention of all the experts and professors who were discussing heatedly in the laboratory.

"The student is too young and does not know the seriousness of the matter. I am sorry to have embarrassed you all." Lu Qian hurriedly tried to smooth things over for Xu Qing.

Huang Xinhua smiled and said, "Professor Lu, since we are communicating, we must absorb opinions from all sides."

“Since your students have ideas, they might as well speak them out.”

"How can we, the seniors, make things difficult for a junior like him?"

A burst of good-natured laughter suddenly rang out in the laboratory.

Lu Qian and Gu Ming then nodded and looked at Xu Qing.

Being stared at by his two teachers and a group of expert professors, Xu Qing couldn't help but sweat in his palms due to nervousness.

After taking a deep breath, Xu Qing said, "Teachers, when I was reading this notebook just now, I found that everyone proposed two reactions, photocrosslinking and photodecomposition, in the discussion this morning..."

Xu Qing spoke haltingly as he expressed his thoughts in a halting manner.

As she elaborated further, many professors' eyes lit up.

Someone couldn't help but quietly admire: "This is a very detailed explanation of the principles of photoresist. Professor Gu, Professor Lu, you have a good student!"

"Who said it wasn't? Beijing Institute of Technology was the best, but I didn't expect your Wudaokou Institute of Technology to be no less outstanding."

……

Faced with everyone's praise, Gu Ming and Lu Qian were happy but also a little confused.

Xu Qing and the others knew that he had talent, but he was not at the level where he could figure out the principles of photoresist after listening for a whole morning.

Soon, Xu Qing finished speaking all his thoughts.

Huang Xinhua was the first to lead the applause, his eyes full of excitement: "Great, it really is true that a good teacher produces good students!"

Everyone followed suit and praised: "Wudaokou Institute of Technology is indeed worthy of its reputation. I don't think we will have much to do with this photoresist research!"

"Professor Gu, Professor Lu, you have such a talented student. You are the envy of others!"

……

Gu Ming and Lu Qian listened to these compliments, feeling humble but more confused.

At this moment, Xu Qing saw that everyone seemed to have misunderstood something, and quickly said: "Dear seniors, everyone has misunderstood. This is not my credit."

"Actually, it was thanks to Li Mu's notes. He wrote down everything you said this morning, and I was able to find some inspiration from it!"

Xu Qing handed over the notes. She knew very well that the credit did not belong to her.

All the professors and experts suddenly looked strange.

After all this praise, the real heroes are still the people from Beijing Institute of Technology?
Gu Ming and Lu Qian didn't care about this embarrassing thing at all and took the notes from Xu Qing curiously.

"It's really well done, you are indeed a genius!" As soon as they got the notes, they couldn't help but exclaim in admiration at the neatly written and well-organized communication records.

But as they watched, their expressions couldn't help but become strange.

Lu Qian pointed to an analysis of photoresist in his notebook, his eyes were strange, and he said in a lost voice: "No, many of the contents above are of great value. If we mention them when we talk about it, there is no way we will not remember them!"

This sound immediately aroused curiosity in everyone in the laboratory.

Everyone came forward and started passing their notes around.

It doesn’t matter if you don’t see it, you will be shocked when you see it!
There are many things in the notes that they never mentioned at all.

These contents can be said to be the key points to solving the photoresist problem.

A group of professors couldn't help but look at Huang Xinhua. They only knew that Li Mu was extremely talented in semiconductors, but they didn't expect that he was also so talented in polymer materials and engineering!
"But why doesn't Li Mu say out what's in his notes himself?" Lu Qian was a little confused.

This was also the question in everyone's mind, and they all looked at Huang Xinhua.

Huang Xinhua was also shocked at this time. He just came back to his senses and heard this question. He couldn't help but smile bitterly and said, "Alas, you don't know that Li Mu's character is too modest!"

……

Huang Xinhua told him everything about Li Mu.

Especially in the research of ultra-thin diamond wheel cutting machine, he frankly admitted that it was because of Li Mu's guidance that he was able to succeed so quickly.

Hearing the professors' praises, Xu Qing's eyes lit up with surprise.

After Huang Xinhua finished speaking, he looked at the shocked people in the laboratory and said, "I have a request. I hope everyone will not expose Li Mu."

As soon as these words came out, Lu Qian couldn't help but ask: "Why is that, Professor Huang?"

"Yeah, we can't say that it was researched by us old guys, right?" Gu Ming followed.

A group of professors and experts nodded repeatedly. It would be a joke if others told them that they were stealing the credit from a junior.

"Everyone please calm down, that's not what I meant." Huang Xinhua waved his hands repeatedly.
