Chapter 121: Lucky lead, 11N monocrystalline silicon rod is released
It is basically an impossible task to maintain a pull of 3 mm per minute when the equipment is semi-failed.
3mm is not 3cm, the lifting process takes 60 seconds!
It takes 60 seconds to lift 3 mm. Even if the lifting speed of the machine and equipment is wrong, can the naked eye really tell the difference?
Ren Guofei didn’t believe it.
Shi Shunyi also didn’t believe it.
No one can do this, not even a top lifting engineer.
Talents from other silicon industry segments, including Wei Hua and Han Ming, are waiting. Is it possible to do it?
Yang Lie didn't pay attention to the eyes around him. Now he was already self-centered and couldn't feel the existence of the outside world.
In his eyes, only the directional speed buttons and equipment lifting rings are left.
With a burning gaze and a determined expression, he stared at the pull-up ring above the quartz crucible smelting furnace, using experience to feel the subtle pull-up speed and make adjustments.
One minute!
Five minutes!
Ten minutes!
Time passed bit by bit.
Because there are only 20 kilograms of 11N polysilicon, he does not need to pull it for eight hours this time, only one to two hours.
But!
Use your naked eyes and experience to make up for the shortcomings of the machine and equipment, and maintain it for one to two hours. This is also an amazing operation.
As time passed, Shi Shunyi’s pupils gradually changed.
At first he was extremely disdainful and did not think that Yang Lie could determine the speed with his naked eyes. This was simply nonsense.
Can!
Half an hour has passed!
His eyes showed a hint of disbelief, the lifting ring rose too evenly!
He is also the chief engineer of Kunpeng Industrial and a leading figure in the silicon industry. Naturally, he also knows a little about silicon rod pulling.
Yang Lie's pulling speed per minute, he was not sure if it was 3 millimeters, but he was very sure that the distance error of the pulling distance per minute was definitely not more than 1 millimeter!
Question!
Surprised!
Incredible!
The expression that kept flashing through Shi Shunyi's pupils also made Ren Guofei look surprised. He vaguely guessed something.
Because he doesn’t understand the silicon industry, he doesn’t understand what the pulling speed of the silicon rod means.
But he also understood that the middle-aged man was using his ordinary body to challenge the half-failed machine!
Looking at Shi Shunyi's micro-expression, Ren Guofei vaguely sensed that the middle-aged man might be about to succeed in the challenge.
If it succeeds...
Ren Guofei can't imagine it...
If this kind of talent can be used by him, wouldn't Kunpeng Industry be able to advance by leaps and bounds?
When his eyes glanced at Chen Xing beside him, Ren Guofei was startled again, and a turmoil arose in his heart.
No trouble!
Yes!
There is no wave on Chen Xing’s face!
It’s the kind of extreme calmness that keeps one’s expression unchanged even if the mountain collapses in front of him!
What kept him from being disturbed at all?
Did he know from the beginning that Yang Lie would definitely be able to do it?
Ren Guofei is full of thoughts. Qu Cheng’s academician network is really great. All types of talents can be recruited to assist the development of Longxing Technology and even its subsidiaries.
He thought about that question again...
Is Chen Xing really an ordinary person?
Could his hidden identity background be the legendary SSS encryption?
One month ago.
He felt that Chen Xing was not worthy of Yao Nana, and wanted to keep Yao Nana at a certain distance from Chen Xing, but now he suddenly realized, could it be that he was trying to get ahead of himself?
To be able to make academicians spare no effort, to be able to gather so many top talents, and to be able to develop so rapidly in a short period of time, Ren Guofei thought a lot and made his own judgment.
Looking at Chen Xing, he didn't notice the change in Ren Guofei's expression at all. Now he only cares about whether he can pull out the 14-inch silicon rod.
If the 14-inch silicon rod can really be pulled out, it will be one step closer to the localization of 12-inch semiconductor silicon wafers, and one step closer to the domestic production of chips. The intensity of Western sanctions will simultaneously weaken.
......
Under the gazes of several people, no one knows how long has passed. It may have been two hours.
"It should be almost done."
Yang Lie did not hesitate and pressed the quick upgrade button of the device.
Next second.
A thick silver rod with a smooth mirror-like surface appeared in front of everyone.
“False mission!”
Yang Lie howled.
After the entire workshop was silent for a few seconds, warm applause and cheers erupted.
"Haha, although this semiconductor silicon rod is short, it is very thick. It should be able to meet the needs of producing 12-inch silicon wafers!"
"The equipment is not enough, so the technology can be used to make up, Engineer Yang is awesome!"
“Engineer Yang is really amazing at judging millimeter distances with the naked eye. Just like the oil seller, he really relies on experience and technology!”
“Engineer Yang is awesome!”
“ Hahaha! After the temperature of the silicon rod cools down, you can go to quality check the purity of several N!"
Under the cheers of the factory workers, Shi Shunyi's pupils trembled, and he looked at the smooth rod in a daze. The silicon rod was stunned.
If you want to make a 12-inch semiconductor silicon wafer, the silicon rod must be 14 inches, because subsequent processing requires grinding the positioning edge, which will lose the original size of the silicon rod, so a size space needs to be reserved.
Shi Shunyi had seen as many as fifty silicon rods, if not a hundred. He could tell at a glance whether they were big enough or not.
Currently, the length of the silicon rods pulled by Longxing Silicon Industry is less than 40 centimeters by visual inspection, but the surface diameter must be about 35 centimeters.
As we all know, the surface diameter of a 12-inch silicon wafer is 30 cm, and there is about 5 cm of free area for polishing. Once the purity of the silicon rod reaches above 9N, it can be further polished and cut.
While Shi Shunyi was stunned, Yang Lie quickly walked up to Chen Xing and said with a little excitement: "Fortunately, the mission has been fulfilled. The 14-inch semiconductor silicon rod has been pulled out."
"I know you can do it. "
Chen Xing smiled lightly.
Golden quality talents, apart from anything else, their technology must be first-rate.
Since Yang Lie dared to propose manual control, he must be confident before saying so, instead of just talking nonsense.
“Thank you, CEO, for your trust.” Yang Lie grinned and explained: “After the purity test is completed, the next step is to polish the positioning edge and then cut it.”
“But It's a pity..."
He sighed and continued: "The length of the silicon rod for lifting is less than 40 centimeters, which is far less than the start-up cost of the equipment. "
So much. The equipment was running for several days, and the power consumption and raw material costs in a single day were a waste of money. In the end, only silicon rods less than 40 centimeters were produced. Yang Lie felt a little guilty, feeling that he had not done enough to test the smelting equipment. obligation.
“You can’t say that.”
Chen Xing shook his head, looked at Ren Guofei beside him and said: "If the 11N14-inch silicon rod is successfully produced, this will be a breakthrough for zero, Mr. Ren, are you right?"
"Well...that's right. ..."
Ren Guofei was stunned for half a second, and nodded quickly in agreement: "A zero-to-one breakthrough cannot only depend on the cost. If 12-inch semiconductor silicon wafers are made domestically, the power consumption of the equipment will be completely It’s negligible.”
How much electricity does all the equipment consume for a day?
Even if the electricity bill is 50,000 yuan a day, you can easily earn it back once you fully master the production of semiconductor 12-inch silicon wafers.
"Which..."
Shi Shunyi, who had been silent for a long time and had a dry throat, suddenly spoke. He stared at Yang Lie, breathing slightly and asked: "Master, where are you? Graduated?"
"Ask me?"
Yang Lie asked in a daze.
Shi Shunyi nodded. He didn't know Yang Lie's name, so he could only address him as "master" and his attitude was very low.
He once thought that he was already a leader in the field of Longguo semiconductor silicon wafers, but he did not expect that there are people outside the world.
Observing with the naked eye and relying solely on experience to adjust the pulling speed of the equipment was something he dared not even think about.
3mm!
3mm per minute!
This is quite an explosive scene in the international semiconductor silicon industry circle.
When asked about his background, Yang Lie did not hide anything and responded with a smile: "I am a graduate of Dongdu University, Department of Mechanical Engineering."
"Dongdu University..."
Shi Shunyi murmured to himself.
If he is a top talent from Toto University, then it barely makes sense. This is the best university in Asia, a super college that has produced 9 Nobel Prize winners and 6 Wolf Prize winners.
Ren Guofei's eyes flashed with envy, he looked at Chen Xing and said with emotion: "For the returned students, Mr. Chen is even more powerful."
In the field of chips, academicians help.
Producing silicon wafers is supported by top overseas returnees.
He is really sour.
Why can’t he recruit the right talents despite his annual salary of one million?
Chen Xing smiled indifferently and said modestly: "Boss Ren's Kunpeng Industry is also very secretive, and there are talents like Chief Engineer Shi."
"Harm!"
Shi Shunyi sighed, waved his hands quickly and said: "Compared with this master, I seem to be a bit of a master of a skill."
If he hadn't seen it with his own eyes, he really wouldn't believe that someone could use a semi-failed machine to improve the efficiency of the machine. Pull out the large 14-inch silicon rod.
Hearing the praise, Yang Lie grinned again, scratched the back of his head and said, "It's all the president who gave me this opportunity."
"Actually, I have a question."
After being polite for a long time, Shi Shunyi looked at Yang Lie and said the purpose: "I wonder if this master can answer me something."
"伱say."
"Your pulling speed is 3 millimeters, right?"
"Well, every minute."
"Can you tell me about the equipment? What is the rotation speed? ”
Pull speed.
Rotation speed.
This is all experience.
Yang Lie did not answer in a hurry, but looked at Chen Xing with a solicituring look, as if asking if he could answer.
The pulling speed and rotation speed of the seed crystal are the key to the production of large-size silicon rods.
"Since Chief Engineer Shi wants to know, then please tell me briefly, Engineer Yang. After all, Mr. Ren can personally deliver the quartz crucible liner."
Chen Xing smiled lightly.
Ren Guofei personally sent the quartz crucible, and they couldn't keep it out of the public eye.
Now Longxing Technology, Kunpeng, Rice and other companies are all allies, at least in the semiconductor field.
Repay a favor and repay a favor.
After Yang Lie received permission, he immediately stated the numerical value:
"To pull a 14-inch large silicon rod, the pulling speed is indeed 3 mm per minute, and the rotation is to the left. The speed It is 5 millimeters per minute, and it will take about eight hours. Remember that the length should not exceed 1.5 meters, otherwise the seed crystal may break. "
"Thank you"
Shi Shunyi wrote it down silently. .
...
While the four people were chatting politely, the temperature of the 14-inch silicon rod dropped rapidly, and half an hour later, it was removed.
Immediately, it is sent to the wire cutting machine to cut off the head and tail of the silicon rod, leaving only the cylindrical silicon body.
If the silicon head and tail are pure enough, they can be cut into seed crystals and used for the next production of large-size silicon rods.
When the silicon head and tail are removed, the original 14-inch silicon rod with a length of 40 cm is now less than 25 cm.
The silicon body that was taken out was not polished in a hurry, but was sent for testing first.
It is also very simple to detect impurities in silicon rods. Use the four-probe method to measure the resistivity of the silicon rod. You can check whether the impurity concentration in the axial direction is consistent. If there is a significant change in the resistivity, then a comprehensive Detected.
Fortunately.
The four-probe test went well.
Han Ming, who was responsible for the testing, also gave a clear reply: "It is 11N purity, and there is no problem with this production."
"Huh——"
Inside the factory.
Hundreds of workers breathed a sigh of relief.
When Ren Guofei heard the news, he immediately congratulated Chen Xing and said: "With the 11N purity 14-inch silicon rod, Mr. Chen is one step ahead of us again."
"Luckily."
Chen Xing smiled lightly.
"Harm!"
Ren Guofei sighed, shook his head and said: "Don't be humble this time, half-failed equipment can pull out a 14-inch silicon rod, Long Developing the silicon industry is not easy.”
“That’s right.”
As soon as he finished speaking, he changed the topic and said, “Mr. Chen, I have an unkind request.”
"Mr. Ren, please speak."
Chen Xing smiled and waited patiently.
A flash of embarrassment flashed across Ren Guofei's face, and he said frankly: "Then I will shamelessly say, can you let Chief Engineer Shi from here come to your factory to observe and study for a few days?"< br>
Shi Shunyi's eyes lit up. He had actually had this idea for a long time, but he couldn't say it out loud because of his face.
“This…”
Chen Xing hesitated.
Let Shi Shunyi study for a few days. Doesn’t this make it clear that he wants to learn from his master?
High emotional intelligence: observe and learn.
Low EQ: learn from others.
Ren Guofei also knew very well that such technical things would not be taught easily, and he also threw out his chips and said:
"I won't take advantage of you in vain. The ultra-fine particle shear mixer you asked me to buy last time has already been shipped by sea."
The subtext of this sentence is obvious, it is talking to Chen Xing :
I'm almost getting the machine you want. Now you owe me a favor. If you want to repay the favor, let Shi Shunyi come and study for a few days.
"He is indeed an old fox in the business world."
Chen Xing murmured to himself.
Can he refuse?
Unless you don’t want the ultra-fine particle shear mixer, you can’t refuse it at all.
It’s impossible to say that you want someone else’s machine and owe someone a favor, but then give them nothing. That’s basically impossible.
Favor debt, the cost of repaying the debt is high!
There was no other way, Chen Xing could only nod slightly and said: "They are all from the Domestic Alliance. Since Mr. Ren said so, let Chief Engineer Shi come to our factory to guide the work for a few days."
He didn't talk about learning, but about guidance, which gave Shi Shunyi enough face.
Hearing this, Shi Shunyi immediately showed a look of surprise and said: "Then please trouble Mr. Chen, if you are willing to take me in for a few days."
"As for domestic alliances, they all help each other."
Chen Xing responded lightly.
Everyone here knows that the words are polite and the domestic alliance is true, but mutual help requires prerequisites.
If you need technology but not technology, and equipment but not equipment, then what does the Domestic Alliance want you to do?
Chips! Very important!
Ren Guofei glanced at the time and pretended to be surprised: "Time flies so fast, and it will be night before you know it, so I won't bother you and let Mr. Chen take the first step."
"I'll see you off."
Chen Xing made a gesture of invitation.
It was really late now, and he didn't think about trying to persuade her to stay.
The two came to the parking lot together. When Ren Guofei drove away and the taillights of the vehicle disappeared, Chen Xing looked away and murmured:
"We have completed the 11N purity monocrystalline silicon rods. After completing the most important step, the next step is rolling and slicing.”
When he returned to the factory, because he had learned his lesson, he did not let the engineers rush to roll grinding, but asked them to carefully first. Check your equipment to make sure nothing goes wrong.
He didn’t want to waste all his efforts again.
