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 doesn’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 eyes around him. Now he was already self-centered and couldn’t feel the existence of the outside world.

As far as he can see, all that’s left now is the directional speed buttons and the device’s lifting loop.

With a sharp gaze and a firm 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 passes bit by bit

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!

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 didn’t think 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 little about silicon rod lifting.

He was not sure whether Yang Lie’s pulling speed per minute 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!

Incredible!

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 realized 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 shocked again, and a turmoil arose in his heart.

No trouble!

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 has a lot 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 problem 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 bring together so many top talents, and 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 the domestic production of chips. The intensity of Western sanctions will be weakened simultaneously.

……

Under the gaze 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’s eyes.

“Fulfill the mission!”

Yang Lie howled loudly

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 and should be able to meet the needs of producing 12-inch silicon wafers!”

“We don’t have enough equipment, 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!”

“Yang Gong 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 were shaken, 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 fifty silicon rods if not a hundred. He could tell at a glance whether they were of sufficient size.

Nowadays, the length of the silicon rods pulled by Longxing Silicon Industry is only 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 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

Golden quality talents, aside from other things, 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, President, 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.”

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, Mr. Ren, are you right?”

“Hmm…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 can be completely ignored.”

How much electricity does it cost to run all the equipment 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 and asked with a slight breath:”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 semiconductor silicon wafers in Longguo. Unexpectedly, 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 Dongdu University, Department of Mechanical Engineering.”

“Tokyo University…”

Shi Shunyi murmured to himself

If he is a top talent from Toto University, then it barely makes sense.

loadAdv(7,3);

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.”

Developing chips with the help of academicians

Working on silicon wafers, with help from top overseas returnees

He is really 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, is also very secretive. There are 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 really 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:”I wonder if this master can answer a question for me?””

“豼说”

“Is your lifting speed 3 mm?”

“Well, every minute”

“Can you tell me, what is the rotation speed of the device?”

Lifting speed

spinning speed

This is all experience

Yang Lie did not answer in a hurry, but looked at Chen Xing with solicitous eyes, 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 Engineer Yang, just tell me briefly. After all, Mr. Ren can personally deliver the quartz crucible liner.”

Chen Xing smiled lightly and said

Ren Guofei personally delivered 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.

Repay favors and repay favors

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 seed crystal may Will break”

“grateful”

Shi Shunyi silently wrote down

……

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.

Then, 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 inspection is required.

Fortunately

All goes 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 11N purity 14-inch silicon rod, Mr. Chen is one step ahead of us again.””

“lucky fluke”

Chen Xing smiled lightly and said

“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 patiently for the next chapter

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 say no?

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, you owe someone a favor, and then you don’t give them anything. 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 please trouble Mr. Chen, are you willing to take me in for a few days?””

“Domestic alliances help each other”

Chen Xing responded calmly

Everyone here knows that they are just polite words. The domestic alliance is true, but there are prerequisites for helping each other.

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 anymore. I’ll go ahead, Mr. Chen.””

“I’ll give it to you”

Chen Xing made a gesture of invitation

It’s really late now, and he doesn’t want to try to persuade him 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 step 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 let the engineers rush to grind, but asked them to carefully check the equipment first to ensure that nothing went wrong.

He doesn’t want to waste all his efforts again
