Chapter 270 The first electronic industrial silicon monocrystal
Fang Yinghong thought for a while and chose to support a foreign factory. Although she would have to leave home for a while, she did not want to give up this opportunity. Given her situation, If you want to get to the level of an engineer, it will be difficult without accumulating some impressive results.
Unexpectedly, Liu Rongguo chose to stay in the factory. It is said that compared with staying in the factory, the pit of supporting external factories is bigger and can accommodate more cakes.
You must know that in the trial production of a new thermocouple, there are not necessarily three holes that can be filled by three people. Besides, it is not necessarily possible that he can be filled.
So staying in the factory is definitely not as good as the support, but the reason he gave is also very strong: "I am getting married, and in these few months, I am too busy."
When Gao Zhendong heard this, he was also happy for him. This was the same as me: "Hey, congratulations, that's OK." At that time, it was Liu Rongguo who was responsible for burning electrodes with Gao Zhendong. Now it would be just right for him and Liang Fafa to cooperate in developing new thermocouples.
After dividing the cake brought back by Gao Zhendong, several people left Gao Zhendong's office.
But they deserve their share of the cake. These people followed Gao Zhendong and made the K-type thermocouple. They have an inherent advantage, so they deserve to be fed.
Even if this matter is discussed openly, not only is there no yin and yang, but also thanks to the atmosphere of the third rolling mill.
When Liu Rongguo was about to go out, he was stopped by Gao Zhendong: "Rongguo, wait."
Liu Rongguo turned around and came back: "Director Gao, is there anything else?"
Gao Zhendong remembered that he had a lot of extra tickets and said with a smile: "If you are short of any tickets for the wedding, tell me and I will give them to you. Don't take the risk to get rid of them, you hear me."
Although the ticket transaction is It's a semi-open secret, but trading is prohibited by regulations, so it's not worth it if you're caught cheating.
When Liu Rongguo heard this, he was very happy. It felt comfortable to work with Director Gao. My own family is still worried about the mismatch between the two transfers.
As for why it’s not “three turns and one beep”? Because he is not planning to buy a watch or a radio. These two things are somewhat luxurious these days and are far less affordable than bicycles and sewing machines. Seeing that Liu Rongguo is getting better and better at his job, he is already a level 12 technician and will definitely be upgraded in the future. Yes, just add more slowly.
Seeing Liu Rongguo walking out of the office with great joy, Gao Zhendong shook his head with a smile and began to work on his own affairs.
After getting home from get off work, he washed his face and drank the tea brought by Lou Xiaoe. Gao Zhendong was enjoying himself when he saw Lou Xiaoe approaching mysteriously: "Guess what's new in the yard this afternoon? ?”
Looking at her gossipy aunty behavior, Gao Zhendong couldn’t help but secretly laugh at Lou Xiao’e’s integration too quickly.
He shook his head: "I can't guess, let me tell you."
Lou Xiao'e laughed and said: "Haha, Master Liu and Silly Zhu are having sex in the backyard."
"Huh??" To be honest, in Gao Zhendong's opinion, these two people should not be able to stand up to each other. of.
Although Shazhu has a bit of a rough-and-tumble temper, under normal circumstances he won’t bite anyone he sees. He is quite respectful to the stewards, but at most he really can’t stand Liu Haizhong and Yan Bugui. When looking at the eyes, there are two sentences of yin and yang.
Although Liu Haizhong wants to control everyone, he has nothing to do with Silly Zhu, and Silly Zhu has no clues for him to catch. In addition, Silly Zhu has a good relationship with Gao Zhendong now, and Liu Haizhong treats him badly. He kept a respectful distance and could not afford to offend but could afford to hide.
“Tell me, tell me.” Gao Zhendong suddenly became interested. Who said that technical people don’t like to hear gossip? The programmers he had met in his previous life were also very interested in gossip.
Seeing Gao Zhendong's interest, Lou Xiao'e started talking vividly while cooking.
The reason was that Bangge came back from school at noon. The child was naughty and was caught by Liu Haizhong who worked the night shift. Lou Xiaoe was reviewing the specific naughty method and was not sure.
In short, he was caught by Liu Haizhong. The second uncle, Comrade Comrade, can't control him. It's better to catch a child and control him.
Children can’t stand being frightened, so Liu Haizhong was happy, and Banggeng was frightened to tears in a few seconds.
Si Zhu happened to be passing by and felt that the bangs were making a fuss, so he protected the bangs.
Silly Zhu's method was quite interesting. Without asking anything, he slapped Banggeng's butt twice, and then pulled him behind him.
He turned around and started to say that Liu Haizhong was arguing with children. The opportunity that Liu Haizhong finally caught was gone, so he started arguing with Silly Zhu.
After a back and forth, maybe they got angry, and the two started to quarrel.
There were not many people in the yard, and the scene was not too noisy, but Liu Haizhong’s words were a bit out of line.
"Going out of line? How to go out of line?" Gao Zhendong was interested in this.
"Probably it means that Banggeng is not called Silly Zhu Dad. Why do you pretend to be the father of Silly Pillar? I can't remember the exact words, but that's probably what it means."
Lou Xiao'e came to the yard after all. Not long, Liu Haizhong’s words were too down-to-earth, so it’s good that she could understand the meaning, but she couldn’t remember the original words. When Gao Zhendong heard this, he smiled. It's hard to talk about this.
Then he shook his head. Although Liu Haizhong’s starting point was hard to say, there was nothing wrong with what he did.
But these words are not what the man in charge of the yard should say.
Lou Xiao'e seemed to have thought of something: "Zhendong, what does Master Liu mean? Shazhu and Sister Qin."
Gao Zhendong smiled, and you realized what Liu Haizhong meant. Your transmission delay is too high. It's big.
But this thing doesn’t happen now, but we can’t let it pollute my Xiao’e’s pure heart: “I think too much, Liu Haizhong is probably angry and talking nonsense, why do you listen to him?”
Lou Xiao'e said "Oh" obediently and continued to prepare dinner.
The next day, Saturday, just as Gao Zhendong arrived at the office, Yu Yuncheng came over. The drawing of silicon single crystal was ready.
Yu Yuncheng seemed a little excited, but not nervous. After all, after Gao Zhendong and his repeated adjustments and tests, and the precedent of ruby single crystal drawing, he was quite confident about the test results.
The officially drawn seed crystal was purchased from the Chinese Academy of Sciences. It is a little bit as big as 3mm*3mm. Gao Zhendong didn’t know where this thing came from in China, so he could only make a blind guess with the respectable person. The silicon single crystal the lady brought back may have some connection.
The control cables are still pulled from Gao Zhendong’s computer room. There is only one control terminal consisting of XS-59 and JP59 in the single crystal furnace laboratory.
Everything was ready, Yu Yuncheng looked at Gao Zhendong: "Director Gao, shall we start?"
Gao Zhendong nodded: "Start!"
Following Yu Yuncheng's order, the power switch was turned on. There was a "buzz" sound, the sound of electricity sounded, and an orange-yellow light gradually appeared in the observation window of the single crystal furnace.
The whole process is similar to that of ruby single crystal pulling, and the processes are similar. The main difference lies in the duration of the process flow, the switching node time, and the switching conditions.
However, the overall situation is under the control of the experimental group. The only difference from the ruby pull is that when the shoulder pull starts, the equal diameter control does not require Yu Yuncheng or other experimenters to be nervous. Instead of giving instructions while staring at the observation window, he stared leisurely at the observation window just in case. The real input source of the crystal diameter was no longer the human eye, but a row of photoelectric components on the camera monitor.
The process was smooth and no accidents occurred.
While waiting for the crystal to be pulled, the two of them stared at the experiment and chatted.
This time they were going to pull a big one if they wanted to officially pull it, otherwise it would be boring, so the finished product this time was much larger than the last time, when the ruby crystal was more than 10 centimeters long, and it also took longer.
Due to the material itself, pulling ruby can only reach that specification. This time pulling silicon single crystal is different. Gao Zhendong and Yu Yuncheng’s plan is to pull 120mm, which is about the same size as Gao Zhendong. The silicon single crystal rod used for 5-inch wafers in the previous life was almost the same, and its diameter was almost the same as the total length of the ruby crystal. The two are incomparable.
As for why not draw 5 inches? Isn’t this nonsense? This is our own equipment, our own technology, and we set our own standards. We must use the standard international unit system used in China.
This furnace was designed by Gao Zhendong in his previous life to pull large-diameter silicon single crystals. It had a high starting point and was not comparable to the technology at this time.
"Old Yu, it's your first official pull, how are you doing?" Gao Zhendong actually wasn't too worried, he was just idle, just chatting.
Yu Yuncheng smiled and said: "Eighty to ninety percent. To be honest, the argon gas I have used may have been more than the air I have breathed in my whole life. If I was not sure, I would have killed myself, haha." < br>
Gao Zhendong burst into laughter. Is this the technological version of "I eat more salt than you have eaten, and the bridges I have walked are longer than the roads you have walked"?
But 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 understood it thoroughly.
This means that as long as the test is successful, Gao Zhendong can leave the single crystal furnace technology line to Yu Yuncheng to promote it and do other things himself, such as semiconductor manufacturing.
This can be regarded as the technological version of La Zhuanding, Gao Zhendong thought.
Like the two leaders, the other experimenters were also in a relaxed mood. Although things were tense and orderly, their moods were not tense. Instead, they had a sense of naturalness.
In this atmosphere, time passed quickly. Following a series of instructions from Yu Yuncheng, after cooling for a while, the first silicon single crystal rod was taken out of the furnace.
The whole body is in the shape of a long cylinder, with obvious traces and characteristics of crystal pulling at both ends. The whole body is blue-black or silver-black or gray-black. In short, Gao Zhendong can’t be sure about the color. He is not an artist. At a glance You can spot the color accurately. In my previous life, when I chased my senior sister, I had never figured out the lipstick color number.
The entire silicon single crystal rod reflects the luster and is very beautiful.
Although everyone has seen a lot of crystal rods pulled out, but when you think about it, if nothing unexpected happens, this may be the first qualified silicon single crystal rod, so you can’t help but feel that this thing is better than the previous ones. beauty.
