Siheyuan: Starting from a fitter

Chapter 67 Chip Manufacturing First Steps

After hearing the voice, Zhao Ting walked out and saw a person Li Guocheng was carrying. Her face changed. Based on her knowledge of Li Guocheng, she would never take the initiative to bully others.

"what happened?"

"Send you a big gift," Li Guocheng repeated.

As he spoke, he grabbed the hair with the other hand to expose Hu Tianqi's face.

"Hu Tianqi! Why is he in your hands?"

"Let's talk after we enter the house." Li Guocheng carried Hu Tianqi and walked towards the door. When passing Zhao Ting, he secretly patted her on the buttocks, which received a coquettish look from the other party.

Li Guocheng threw Hu Tianqi on the ground, took 56 and a half from behind, and handed it to Zhao Ting.

"Are you not injured?" After the three of them sat down, Zhao Ting asked about Li Guocheng's physical condition with concern.

"Oops." Li Guocheng held his head and fell towards Zhao Ting. She saw through it and pushed him up with both hands. Then he lightly kicked Li Guocheng's calf and glanced at Aunt Liu from the corner of his eye, which was full of warning.

Li Guocheng smiled shamelessly and briefly recounted what had just happened.

"He targeted me with his gun but did not fire it. He was probably afraid that the shooting would attract the police or patrols, so he deliberately climbed on the roof so that I could find him and lure me to pursue him. Then he lurked at the entrance of the alley and attacked me. It was not me. With super strong senses, ordinary people might fall victim to it.”

"The timing of the sneak attack is very clever. At the entrance of the alley, most people rush out or poke their heads to observe the opponent's whereabouts, and will not pay attention to the corner of the alley right in front of them. They are indeed enemy agents."

"I didn't expect that he had been lurking in the steel rolling mill for more than 20 years. He has never been married. The information shows that his family members died in the war. He is probably an impostor. We are investigating. It is probably difficult. The society was very chaotic at that time and there is no evidence to investigate." Zhao Ting explained.

During the chat, Li Guocheng, who had been paying attention to Hu Tianqi, stood up and walked to Hu Tianqi's side, squatted down, and pointed a knife at the aorta.From getting up to taking action, it was very sudden. Zhao Ting was thoughtful and Aunt Liu was shocked.

"This kid just woke up and is pretending to be dead. Since he wants to pretend to be dead so much, I will help him," Li Guocheng explained.

"Where did you learn this?" Zhao Ting gestured with her hands to chop.

"Don't forget, I'm a doctor. Although I don't have a certificate, I haven't put on shoes yet."

This kind of turning point is relatively new to people of this era. Zhao Ting burst out laughing, while Aunt Liu looked confused.

Zhao Ting noticed Aunt Liu's expression and explained, "Guocheng means that he is a barefoot doctor."

Aunt Liu reacted and scolded with a smile: "You stinky boy."

The car also arrived at this time, and Li Guocheng helped carry Hu Tianqi and threw him at the foot of the back seat.

"Pay attention to this guy on the road." Li Guocheng knew that he was not qualified to follow him yet.

"Go back. There will probably be interrogations and investigations again in the past few days. You may not be able to come back at night," Zhao Ting asked before getting in the car.

"Then I'll hold the door open for you." Li Guocheng saw Zhao Ting's embarrassed expression and said quickly, "Just kidding, I'll come see you next weekend."

"Cycle slowly on the road," Zhao Ting reminded her, and the car drove away quickly.

After an uneventful journey back home, I took out a semiconductor-related book from the bookcase and started reading.Behind Li Guocheng, the bookshelf is already filled with books, mainly books on physics, semiconductors, and machinery, as well as some beautifully painted comic books.

Li Guocheng took time to buy these at a buying station near Wudaokou Vocational and Technical College on weekends. Of course, before each visit, he would put on makeup carefully to avoid trouble in the future by being recognized. With the help of his mind power, he would change several key positions and paint his face. If it's gray, even an acquaintance might not be able to recognize it at first glance.

In order to facilitate the purchase of 'waste', I became acquainted with the boss half a year ago and invited the old man to drink frequently.The old man was quite wary at first. When Li Guocheng bought some used books from the technical school every time he went there, and said that the technical school here was the palace in his mind, the old man let down his guard. After drinking too much, he would use the palace to harass Li Guocheng.

The old man was also kind and helped Li Guocheng to keep the books from this technical school for Li Guocheng to choose from.

The old man did not expect that in recent months, more and more books would come out of the technical school, and occasionally some strange objects would be received, which the old man bought as scrap metal.

Several of them were placed on the experimental bench in the secret realm. By the way, the experimental bench was also purchased from this acquisition station.

A few days ago, Li Guocheng felt that the old man had collected a lot of things, so he asked for leave and went to the collection station. Unexpectedly, he gave Li Guocheng a big surprise. He actually found an open large wooden box in the corner, which contained gray-black powder and It is very similar to what I saw in my fellow laboratory.

"Uncle, what is this?"

"Hey, when a few students were pushing a cart to sell scraps, they said it was a good thing. I thought it was coal dust, so I rubbed it with my hands. Damn, I don't know what it is, so I didn't accept it. A few students threw it away. I dropped off my things and left, and I was just waiting for my son to come over and help me throw them away."

Li Guocheng didn't dare to say anything. He picked a dozen books and when he left, he casually offered to throw them away. The old man was very happy and even said that he would leave something good for Li Guocheng next time.

I went out and threw it into a secret place in a deserted corner. After returning home, I found a description in a semiconductor book and I was convinced that it was silicon powder.

My main job now is to learn about semiconductors. I studied electronic automation for my bachelor's and master's degrees in college. I know how to use chips, but I don't know how to make them.My undergraduate course seems to have explained the characteristics and structural principles of transistors in "Basics of Electronic Technology" or "College Physics", but I'm still confused about how to make them.

Now I only have one copy of "Semiconductor Physics" co-authored by Huang Kun and Xie Xide, and another one in Russian. I only caught my attention when I saw the picture on the cover. It was a very strange physics experiment. I opened it to see Here comes the familiar transistor structure diagram.

Some other magazines about semiconductors have no practical significance and are just news-like things.

Do I have to rely on these two books to get chips? I originally thought that Wudaokou Technical School would have a lot of relevant information, but I didn't expect that I only bought two books in exchange.It seems that I will have to visit this technical school in the future.

Li Guocheng took "Semiconductor Physics" and gained a little understanding of how transistors are made. The next main task was to learn Russian.At this stage, I don’t dare to find a Russian translator.Well, Yi Duo couldn't help but comfort himself.

Entering the secret realm, I looked at the three crucibles on the test bench and the only small cube, which was about the size of lead type in a printing factory, 3*3mm. After reading "Semiconductor Physics", I learned that this thing is called a silicon seed. Crystal is the main raw material for pulling silicon single crystal.

This small cube was bought together with the crucible. The old man didn't know the value, and Li Guocheng was also confused. He spent a total of 3 yuan to accept it based on his feeling. For this, the two of them had to bargain for a long time with pale faces.In principle, buying stations all have the types and pricing of purchases, but now is an extraordinary period, the management is relatively chaotic, and the old man is also bold, and he dares to buy anything he encounters.

Put the precious silicon seed crystal into the brocade box and go out to sleep in the secret place.I'll take leave tomorrow and go to the acquisition station again, hoping to find information on Russian learning.
