Technology company, I will become the light of China!

Chapter 121: Lucky to take the lead, 11N monocrystalline silicon rod is released
It is basically an impossible task to maintain a lift of 3 mm per minute when the device is semi-failed.

3mm is not 3cm, the lifting process takes 60 seconds!
It takes 60 seconds to lift 3 millimeters. Even if the lifting speed of the machine is wrong, can the naked eye really tell the difference?
Ren Guofei didn't believe it.

Shi Shunyi also didn't believe it.

This is something that no one can do, not even a top lifting engineer.

Talents in other silicon industry subdivisions, including Wei Hua and Han Ming, are waiting. Is it possible to do it?
Yang Lie didn't pay attention to the gazes around him. Now he was already self-centered and couldn't feel the existence of the outside world.

As far as he could see, all that was left now was the directional speed buttons and the device's lifting loop.

With a burning gaze and a determined look, 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.

1 minutes!

5 minutes!
10 minutes!
Time passed little by little.

Because there is only 20 kilograms of 11N polysilicon, he does not need to pull it for eight hours this time, only one to two hours.

but!

Using the naked eye and experience to make up for the shortcomings of the machine and equipment, and maintaining 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 passed!
There was a hint of disbelief in his eyes. The lifting ring rose so evenly!
After all, he is also the chief engineer of Kunpeng Industrial and a leading figure in the silicon industry. Naturally, he also knows a bit about silicon rod lifting.

Yang Lie's pulling speed per minute, he wasn't sure if it was 3 millimeters, but he was very sure that the error in the pulling distance per minute was definitely not more than 1 millimeter!

question!

be surprised!

Unbelievable!

The look 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 successful...

Ren Guofei couldn't imagine it anymore...

If this kind of talent can be put to use by him, wouldn't Kunpeng Industry be able to advance by leaps and bounds?
When he glanced at Chen Xing beside him, Ren Guofei was startled again, and a turmoil arose in his heart.

No waves!

Yes!

There was no emotion on Chen Xing’s face!

It's the kind of ultimate calmness that doesn't change even when the mountain is collapsing!

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 was thinking a lot. Qu Cheng's network of academicians was really great. All types of talents could 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 be the legendary SSS encryption?

a 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?
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.

On the other hand, Chen Xing 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 knew how much time had passed. It might have been two hours.

"It should be almost there."

Yang Lie didn't hesitate and pressed the device's quick upgrade button.

next second.

A thick silver rod with a smooth mirror-like surface appeared in front of everyone.

"Follow the 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 we have to make do with technology. 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!"

“Gong 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 unanimous cheers of the factory workers, Shi Shunyi's pupils trembled, and he stared blankly at the smooth silicon rod.

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 you need to reserve space.

Shi Shunyi had seen as many as fifty silicon rods, if not a hundred. He could tell at a glance whether they were of sufficient size.

The length of the silicon rods currently pulled by Longxing Silicone 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 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."

Chen Xing smiled faintly.

Among other things, golden quality talents must have first-class technology.

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 used for lifting is less than 40 centimeters, which is far less than the start-up cost of the equipment."

With so much equipment running for several days, the power consumption of the equipment and the cost of raw materials in a single day were all in vain. 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 detect the melting. Equipment Obligations.

"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?"

"Um...that's right..."

Ren Guofei was stunned for half a second, then nodded quickly and agreed: "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 negligible."

How much electricity does it cost to run all the equipment for a day?

Even if the electricity bill is 12 yuan a day, you can easily earn it back once you fully master the production of semiconductor [-]-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 did you graduate?"

"Ask me?"

Yang Lie was stunned and asked.

Shi Shunyi nodded. He didn't know Yang Lie's name, so he could only refer to 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.

3 mm!
3 millimeters 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 the Department of Mechanical Engineering of Dongdu University."

"Toto University..."

Shi Shunyi murmured to himself.

If he was a top talent from Toto University, it would barely make 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 students who have returned from overseas, Mr. Chen is even more powerful."

To engage in chips, there are academicians to help.

When it comes to silicon wafers, we have the help of top overseas returnees.

He is so sour.

Why can't he recruit the right talents even though he offers an annual salary of one million?

Chen Xing smiled indifferently and said modestly: "Kunpeng Industrial, the boss of Ren Ren, also has talents like Chief Engineer Shi."

"Harmful!"

Shi Shunyi sighed, waved his hands quickly and said: "Compared with this master, I seem to be a bit impractical."

If he hadn't seen it with his own eyes, he wouldn't have believed that someone could use a semi-malfunctioning machine to pull out a large 14-inch silicon rod.

After 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 his purpose: "I wonder if this master can give me some answers."

"Tell me."

"Your lifting speed is 3 millimeters, right?"

"Yeah, every minute."

"Can you tell me what the rotation speed of the device is?"

Lifting speed.

spinning speed.

It's 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, so 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.

A favor is repaid, a favor is repaid.

After Yang Lie received permission, he immediately said the value:

"To pull a 14-inch large silicon rod, the pulling speed is indeed 3 mm per minute. The rotation is to the left at a speed of 5 mm per minute. It takes about eight hours to pull. Remember that the length should not exceed 1.5 meters, otherwise the crystal will It might break."

"grateful."

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 afterwards, it is sent to a 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 40-inch silicon rod with a length of 14 centimeters is now less than 25 centimeters.

The removed silicon body was not rushed to be polished, 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 test is required.

Fortunately.

All went well with the four-probe test.

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."

"call--"

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 11-inch silicon rod with 14N purity, Mr. Chen is one step ahead of us again."

"Happy luck."

Chen Xing smiled lightly.

"Harmful!"

Ren Guofei sighed, shook his head and said, "Don't be humble this time. The semi-failed equipment can pull out a 14-inch silicon rod. Longxing Silicon Industry is not simple."

"correct."

As soon as he finished speaking, he changed the subject and said, "Mr. Chen, I have a heartfelt request."

"Mr. Ren, please tell me."

Chen Xing smiled and waited quietly for the next step.

Ren Guofei's face flashed with embarrassment, and he said frankly: "Then I will say it shamelessly, is it possible for my chief engineer Shi to come to your factory to observe and study for a few days?"

Shi Shunyi's eyes lit up. He had actually had this idea for a long time, but he couldn't express it 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 emotional intelligence: learn from others.

Ren Guofei also knew very well that such technical things would not be taught easily. 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 very obvious, it is saying 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 commercial field."

Chen Xing murmured to himself.

Can he refuse?
Unless you don't want the ultrafine 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.

The cost of repaying a debt of favor is high!

There was no other way. Chen Xing could only nodded slightly and said: "They are all from the Domestic Alliance. Since Mr. Ren has 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.

When Shi Shunyi heard this, he immediately showed a look of surprise and said: "Then I'll 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 calmly.

Everyone here knows that they are just polite words, 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. I'll go ahead, Mr. Chen."

"I'll send it to you."

Chen Xing made a gesture of invitation.

It was really late now, and he didn't think about trying to stay.

The two of them 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 most important part of the 11N purity single crystal silicon rod, and the next step is rolling and slicing."

When he returned to the factory, because he had learned his lesson, he did not ask the engineers to rush to grinding, but asked them to carefully check the equipment first to ensure that nothing went wrong.

He didn't want to waste all his efforts again.
