Chapter 270 The First Silicon Single Crystal for Electronics Industry
Fang Yinghong thought for a while and chose to support the foreign factory. Although she would have to leave home for a while, she did not want to give up this opportunity. Given her situation, it would be difficult for her to reach the level of engineer without accumulating some outstanding achievements.

Unexpectedly, Liu Rongguo chose to stay in the factory. It is said that compared with staying in the factory, the opportunity to support other factories is bigger and can accommodate more cakes.

You have to know that the trial production of the new thermocouple does not necessarily require three people to fill the three gaps. Besides, it is not certain that he can fill the gaps.

So staying in the factory is definitely not as good as receiving support, but the reason he gave was also very strong: "I am preparing to get married in the next few months, and I am too busy."

Gao Zhendong was also happy for him when he heard this. He was just like me: "Oh, congratulations. That's fine."

Gao Zhendong thought about it and decided that this was a good idea. When the K-type thermocouple was being trial-produced, it was Liu Rongguo who was responsible for burning the electrodes with Gao Zhendong. Now it would be just right to let him work with Liang Faming to make a new thermocouple.

Several people divided the cake that Gao Zhendong brought back and left Gao Zhendong's office.

But they deserve to share the cake. The K-type thermocouple was invented by these people following Gao Zhendong. They have an innate advantage, and they deserve to have their fill.

Even if this matter is brought out and discussed openly, it cannot be explained away. We have to thank the Third Rolling Mill for its generosity.

When Liu Rongguo was about to go out, Gao Zhendong stopped him: "Rongguo, wait a minute."

Liu Rongguo turned back and said, "Director Gao, is there anything else?"

Gao Zhendong remembered that he had a lot of extra tickets, and said with a smile: "If you need any tickets for your wedding, tell me and I'll give them to you. Don't risk your life to buy them, do you understand?"

Although ticket trading is a semi-public secret, it is prohibited according to regulations. If you are unlucky and get caught, it will not be worth it.

Liu Rongguo was very happy when he heard this. It was comfortable to work with Director Gao. He was worried about not having enough money at home.

As for why it was not "three turns and one ring"? Because he was not planning to buy a watch or a radio. These days, these two things are a bit of a luxury and are far less affordable than bicycles and sewing machines. Seeing that Liu Rongguo's work was getting better and better, and he was already a 12th-level technician, he would definitely be promoted in the future, so he could just buy more slowly.

Watching Liu Rongguo walking out of the office happily, Gao Zhendong smiled, shook his head, and started to busy himself with his own things.

After getting off work, Gao Zhendong returned home, washed his face, and drank the tea brought by Lou Xiao'e. He was just enjoying himself when he saw Lou Xiao'e approaching him mysteriously: "Guess what happened in the yard this afternoon?"

Looking at her gossipy auntie behavior, Gao Zhendong couldn't help but laugh at how Lou Xiao'e integrated into the group too quickly.

He shook his head: "I can't guess, tell me about it."

Lou Xiao'e laughed and said, "Haha, Master Liu and Sha Zhu are fighting in the backyard."

"Huh?" To be honest, in Gao Zhendong's opinion, these two people should not be able to match the bull.

Although Sha Zhu has a somewhat unruly temper, under normal circumstances he would not bite anyone he saw. He was quite respectful to the managers and at most would say a few words to Liu Haizhong and Yan Bugui when he really couldn't stand them.

Although Liu Haizhong wants to control everyone, he has no way to deal with Sha Zhu. Sha Zhu has no handle for Liu Haizhong to catch. Besides, Sha Zhu has a good relationship with Gao Zhendong now, so Liu Haizhong keeps his distance from him. He can't afford to offend him, but he can avoid him.

"Tell me, tell me." Gao Zhendong suddenly became interested. Who said that people who work in technology don't like to listen to gossip? The programmers he had met in his previous life were also very interested in gossip.

Seeing that Gao Zhendong was interested, Lou Xiao'e began to describe the situation vividly while cooking.

It all started when Banggeng came back from school at noon. The child was naughty and was caught by Liu Haizhong, who was off night shift. Lou Xiaoe was reviewing and was not sure how naughty he was.

Anyway, he was caught by Liu Haizhong, and Comrade Erdaye couldn't control him anymore, so it would be good to catch a kid and control him for fun.

Children can't stand being scared. Liu Haizhong was happy, but Banggeng was scared to tears.

Sha Zhu happened to pass by and thought Liu Haizhong was making a fuss out of nothing, so he protected the stick stem.

Sha Zhu's method was quite interesting. He didn't ask anything. He slapped Bang Geng twice on the buttocks and then pulled him behind him.

He turned around and started to blame Liu Haizhong for arguing with a child. Liu Haizhong's chance, which he had finally caught, was gone just like that, so he started arguing with Sha Zhu.

After a while, perhaps because they were angry with each other, the two started arguing.

There weren't many people in the yard, so the scene wasn't too drastic, but Liu Haizhong's words were a little out of line.

"Out of line? What's out of line?" Gao Zhendong was interested in this.

"It's probably saying that Banggeng doesn't call Shazhu dad, so why are you pretending to be a dad? I can't remember the exact words, but that's probably what it meant."

After all, Lou Xiao'e had not been in the courtyard for long. Liu Haizhong's words were too down-to-earth, so she was lucky to understand the meaning, but she could not remember the original words. Gao Zhendong laughed when he heard this. It was hard to say.

Then he shook his head. Although it was hard to say what Liu Haizhong's starting point was, there was nothing wrong with what he did. It was the actions that mattered, not the intentions.

However, this is not something the man in charge of the courtyard should say.

Lou Xiaoe seemed to remember something: "Zhendong, what does Master Liu mean? Could it be that Shazhu and Sister Qin..."

Gao Zhendong laughed, and then you realized what Liu Haizhong meant. Your transmission delay is too large.

But this has not happened yet, so I can't let it pollute my Xiao'e's pure heart: "Don't think too much, Liu Haizhong must have scolded me too much, he is talking nonsense, why listen to him."

Lou Xiao'e said "Oh" obediently and continued to prepare dinner.

The next day, Saturday, Gao Zhendong had just arrived at the office when Yu Yuncheng came over. The silicon single crystal was ready for pulling.

Yu Yuncheng looked a little excited, but not nervous. After all, after repeated adjustments and experiments by Gao Zhendong and him, and with the precedent of ruby ​​single crystal pulling, he was quite confident about the test results.

The seed crystal that was officially pulled was purchased from the Chinese Academy of Sciences. It was only a little bit bigger, 3mm*3mm. Gao Zhendong didn't know where this thing came from in China. He could only guess that it might have some connection with the silicon single crystal brought back by that respectable lady.

The control cables were still pulled from Gao Zhendong's computer room. There was only one set of control terminals consisting of XS-59 and JP59 in the single crystal furnace laboratory.

Everything was ready. Yu Yuncheng looked at Gao Zhendong and said, "Director Gao, shall we start?"

Gao Zhendong nodded: "Let's start!"

Following Yu Yuncheng's order, the power switch closed, and with a "buzz" sound, the sound of electricity rang out, and an orange-yellow light gradually appeared in the observation window of the single crystal furnace.

The whole process is similar to the pulling of ruby ​​single crystals, and the procedures are almost the same. The main difference lies in the duration of the process flow, the transition node time, and the transition conditions.

However, everything was generally under the control of the experimental group. The only difference from the ruby ​​pulling was that after the shoulder pulling began, Yu Yuncheng and other experimental personnel no longer needed to stare at the observation window nervously and give instructions for diameter control. Instead, they could stare at the observation window leisurely just in case. The real source of crystal diameter input was no longer the human eye, but a row of photoelectric elements on the camera monitor.

The process went smoothly without any accidents.

While waiting for the crystal to be pulled, the two watched the experiment and chatted.

This time they were going to make it big, otherwise it would be boring, so the finished product was much bigger than the last ruby ​​crystal which was more than 10 centimeters long, and it took longer.

The reason why rubies can only be pulled to that specification is due to the material itself. This time, pulling silicon single crystals is different. Gao Zhendong and Yu Yuncheng plan to pull 120mm ones, which is roughly the same as the silicon single crystal rods used for 5-inch wafers in Gao Zhendong's previous life. The diameter is almost the same as the total length of the ruby ​​crystal. The two cannot be compared.

As for why we don't draw 5 inches? This is nonsense. This is our own equipment, our own process, and we set our own standards. We must use the standard international system of units used in China.

This furnace was designed by Gao Zhendong in his previous life for pulling large-diameter silicon single crystals. Its starting point is very high and cannot be compared with the technology of today.

"Old Yu, this is your first official tour, how are you feeling?" Gao Zhendong wasn't really worried, he just had nothing to do so he decided to just chat about it.

Yu Yuncheng laughed and said, "About 80 to 90 percent. To be honest, the argon I've used may have been more than the air I've breathed in my entire life. If I wasn't sure, I would have crashed to death, haha."

Gao Zhendong burst out laughing. Is this the technological version of "I have eaten more salt than you have eaten rice, and I have walked across longer bridges than you have walked on roads"?

However, it is a good thing that Yu Yuncheng has this confidence, which shows that he is already very familiar with this thing and has basically mastered it.

This means that as long as the experiment is successful, Gao Zhendong can hand over the single crystal furnace technology line to Yu Yuncheng for promotion and do other things himself, such as semiconductor manufacturing.

This can be considered a technological version of conscription, Gao Zhendong thought.

Like the two leaders, the other experimenters were also in a relaxed mood. Although things were intense and orderly, they were not nervous. Instead, they felt a sense of naturalness as if everything was happening smoothly.

In this atmosphere, time passed quickly. Following a series of instructions from Yu Yuncheng, after cooling down a bit, the first silicon single crystal rod was taken out of the furnace.

The overall shape is a long cylinder, with obvious traces and features of crystal pulling at both ends. The whole body is blue-black, silver-black or gray-black. In short, Gao Zhendong can't tell the color for sure. He is not an artist and can tell the color at a glance. When he was chasing after a senior student in his previous life, he never figured out the color of the lipstick.

The entire silicon single crystal rod reflects light and is very beautiful.

Although everyone has seen many crystal rods, when they think that if nothing goes wrong, this may be the first qualified silicon single crystal rod, they can't help but think that this thing is more beautiful than any other before.
