The Red Era, the Opening University Speech

Chapter 24 Do you know wafer cutting technology?

Seeing that Huang Xinhua was becoming more and more talkative, Li Mu started to panic.

If Huang Xinhua asked him any random questions, such as principles, sources of ideas, etc., Li Mu would be at a loss.

"Professor Huang, I wonder if you have done any research on the industrial production design of single crystal furnaces. I just happened to see this area recently, but couldn't find any information in the library." Li Mu turned the topic to the area he was familiar with.

"You've asked the right person. I happen to be familiar with this area and have a lot of related books at home. I'll get them for you when I have time." Huang Xinhua looked at Li Mu with appreciation. He was neither arrogant nor impatient, and was studious and inquisitive. He was a good student.

"Actually, I already have some ideas. Professor Huang, why don't you give me some help?" Li Mu said quickly.

He just wanted to change the subject, but judging from Huang Xinhua's expression, he seemed even more interested.

"Okay, then I'll take a look." Huang Xinhua smiled, not thinking that Li Mu could come up with anything.

Li Mu first took out paper and pen from his bag, then took Huang Xinhua and Wang Ya to sit in a pavilion nearby.

Finally, I clicked on the single crystal furnace sketch in my mind.

"Swish, swish, swish~"

Straight lines are drawn on the paper, and each stroke is crisp and neat.

Of course, Li Mu didn't draw the whole thing, he just drew a rough sketch.

The general framework remains unchanged, but some data and details are changed, making the drawing look impressive at first glance, but with many actual problems.

What Li Mu had to do was to fool the two of them first, and then wait for them to realize that there was something wrong with the blueprint and it wouldn't work, and then the matter would naturally come to nothing.

Huang Xinhua was smiling at Li Mu's drawing at first, but later on, his smile gradually disappeared, and he showed a hint of shock:
“Is this an idea?”

"So does the complete process require a single crystal furnace?"

"Please give me some advice, Mr. Huang." Li Mu put pen to paper, and a new design drawing of a single crystal furnace came out.

"Good! Good! Good!" Huang Xinhua stared for a long time and finally couldn't help but exclaimed.

Wang Ya was shocked: "Li Mu, are you really researching this?"

She originally felt sorry for Li Mu giving up his research on the industrial preparation of single crystal silicon.

Unexpectedly, he turned around and took out the drawings of the single crystal furnace.

Moreover, the rigor displayed in the drawing was something Wang Ya had only seen in her teacher, Huang Xinhua.

"It's just based on theoretical deduction, and many data have not been verified yet." Li Mu said.

"It looks like the structure is complete. Wait for me to take a closer look..." Huang Xinhua looked at the design drawing and quickly became immersed in it.

This design is truly amazing!
Whether it is the design concept or the overall layout, it can almost be called a stroke of genius!
Moreover, the structure is so sophisticated that even he has to study it carefully to fully understand it.

Li Mu waited for half an hour, but Huang Xinhua and Wang Ya were still immersed in the design drawings. The latter even took out a notebook and started writing and calculating.

"Professor Huang, I have something else to do..." Li Mu couldn't help but speak.

"You go and do your work first. I'll take the picture first. I'll let Xiaoya give it to you later!" Huang Xinhua waved his hand, not even willing to move his eyes away.

Seeing this, Li Mu breathed a sigh of relief and hurried away.

If he stayed any longer, it would be bad if Huang Xinhua came to his senses and asked him how he designed the drawings.

Return to the classroom and continue the class.

……

When I got home in the evening, my uncle Li Jun greeted me:
"Xiao Mu, come and give me a hand. We are distributing cabbages today."

Li Mu responded: "Okay, I'll put my bag down and come out."

On the way, Li Jun pushed a cart and said:
"Xiao Mu, just help me and your aunt take turns in the queue later, and keep an eye on the cabbages."

"Is this the cabbage stored for the winter in Kyoto?" Li Mu just now remembered the scene he had seen in the TV series.

When we got there, it was crowded with people.

"Everyone line up, don't rush, everyone can get it!"

The people from the street office in front shouted at the top of their lungs, but they could only barely keep the team in order.

Squeezed together with the crowd, it was warm even in the cold weather. Li Mu picked up the book, thought about it, put it down again, and started chatting with his uncle and aunt who were queuing next to him.

He is gradually integrating into this era.

...the next day.

Li Mu had just finished washing up when his uncle Li Jun suddenly came over, looking like he had something to say but was hesitant.

"Uncle, do you have something to talk to me about?" Li Mu took the initiative to speak.

It is usually not his turn to take care of family matters, but the fact that his uncle Li Jun is looking for him means that he is really in trouble.

The 1.80-meter-tall man said shyly, "Xiao Mu, Xiao Lan and Xiao Yu have grown up, and they run around all day. If you have time, how about teaching them to read?"

"Knowing how to read is a good thing. Of course you can. I think it's a big deal!" Li Mu said with a smile.

He was a little puzzled as to why Li Jun was so sneaky, as if he was afraid of being seen by someone.

Li Jun was overjoyed when he heard this, but he also reminded her, "Okay, don't tell your grandma about this, or she will scold me to death."

"Okay." Li Mu smiled.

……

Leave home and come to school.

Li Mu sat in his seat and subconsciously glanced towards Wang Ya's position.

The next moment, Li Mu's eyes suddenly widened: "I'm dazzled, Wang Ya is actually dozing off!"

At the table by the window, Wang Ya's little head moved noddingly, which was actually quite cute.

"What does it have to do with me? I'm just studying." After looking for a while, Li Mu quickly came to his senses and threw himself into studying.

"Ding-ling-ling~" Wang Ya didn't wake up until the bell rang. She glanced at Li Mu and started the class.

At noon, after class.

Li Mu tidied up the notes on his desk and prepared to go eat.

Just then, Wang Ya came over.

There were dark circles under her beautiful eyes.

"Are you so sleepy? Take a leave and rest in the afternoon. You can't concentrate in class." Li Mu spoke first.

Every time this girl comes to see him, something bad happens.

"No!" Wang Ya decisively rejected the suggestion, then patted her smooth face with her hands, trying to sober herself up.

"Li Mu, my teacher and I studied all night yesterday. He asked me to come over and invite you. He said he wanted to talk to you about the design."

Wang Ya looked at Li Mu, her sleepy eyes revealing deep admiration.

Li Mu resisted the urge to turn around and run. The only option now was to "delay". He said with concern:

"You and Professor Huang have been studying all night, so you must be very sleepy. I think you should go back and take a rest first."

"I understand Professor Huang's feelings, but the design is not that easy to realize. You are his student, so you should advise him to take care of his health and then study it slowly in the future."

"Okay, I'm going to eat now."

After Li Mu finished speaking, he picked up his bag and prepared to leave.

Wang Ya was anxious: "I'm not sleepy at all, Li Mu, you should go to the teacher quickly, he really wants to communicate with you face to face as soon as possible."

Seeing that all the classmates around him were looking at him, Li Mu didn't want to argue anymore and said, "Then you have to let me go to the cafeteria to buy something. I can't discuss this on an empty stomach."

"Okay, I'm hungry too, let's go together." Wang Ya thought about it and felt that what Li Mu said made sense, so she nodded in agreement, but she didn't intend to let Li Mu go alone.

Li Mu also knew that Wang Ya was not so easy to deal with.

Li Mu looked at Wang Ya behind him, who was yawning sleepily but still staring at him.

An idea flashed in my mind.

If you don't want to answer a question, the best way is to ask another question.

Li Mu hesitated for a moment and said, "Wang Ya, do you know the wafer cutting technology?"

Wang Ya tilted her head, somewhat puzzled as to why Li Mu would ask such a common sense question: "Of course I know. The scribing method is widely used in wafers around the world now, which is similar to the principle of scratching glass..."

"But even with this kind of technology, we can't produce it. The only diamond blade dicing and cutting machine that Beijing Institute of Technology has to be purchased from the north. Even professors have to apply for it first if they want to use it."
