Homecoming of Rebirth

Qi Lei nodded, "It's okay!"

Sam looked at the road, his eyes drifted towards Qi Lei, "Penguin... If I remember correctly, you own 34% of the shares, right?"

Qi Lei, "That's right!"

Sam, "So how much is left now?"

Qi Lei, "There is still 30% left."

"What!?" Sam yelled, "You cashed out 4%?"

The brain is running fast, 4%... According to the current stock price, there must be 70 billion RMB, right?

"FUCK! I'm rich!"

Qi Lei was listening to the music, and everyone was also listening to the music, "What are you thinking? I'll give the 4% to Uncle Geng, what's the cash!"

"Gah!?" Sam almost choked to death, "Give...Geng..."

Uncle Geng spoke in the back row, "Yes, give it to me! Do you have any opinions?"

Sam's face drooped, "No."

Ask Qi Lei, "Then how much did you cash out?"

Qi Lei pretended to be stupid, "What cash? The stock price hasn't peaked yet, so what should I cash?"

Sam, "..."

It's over, you're still a pauper!

Well, he is in China, so he didn't know Qi Lei and Paulson's showy operation, as long as Qi Lei wants to have cash flow, he has to sell his shares!

"Hey!" The whole person lost all energy, "Why are you explaining to Byron?"

He, the person in charge of the Shanghai Laboratory, came to the airport to pick up people in person, isn't it just for a little money?

The last struggle, "Qi, can't you cash out a little less stock?"

Qi Lei purposely watched him twitch, and said firmly, "No!"

Sam, "..."

"However!" Qi Lei made a sharp turn, "I do have some money, do you want to use it?"

Sam's eyeballs didn't come out: "I want to! I really want to. How many!?"

Qi Lei grinned widely, reappearing the style of a local tyrant.

Didn't say the number, just said, "Should be...enough for you!"

Sam, "..."

Just like that, Qi Lei was dragged into the meeting room by Sam before he took off the coat he put on in Seattle.

Byron August, as well as Mr. Nan who rushed over from Changxiang in the capital, and other researchers in the laboratory are waiting there!

It made Qi Lei grin, there are quite a lot of debts!

Tucao Nanlao, "I'm going back to the capital tomorrow, can't I wait all day?"

Nan Lao didn't bother to talk to him, "I came to see you. I miss you, what's the hurry?"

Qi Lei, "Tsk tsk, it's not cheap for you to think about it."

Ordinarily, Nan Lao is now asking Qi Lei for money, he should be asking Wang Zhendong for money.

However, there are two reasons:

First, some projects invested by Nanlao cannot be placed under the name of Imagination, and must be independent, which is related to the overall industrial structure layout of Dasanshi.

Second, some projects cannot even be supported by imagination.

As for Qi Lei, he has a net worth of hundreds of billions, so of course he wants to eat the rich.

Over there, Byron was talking to Sam.

Sam, "Reliable word, he's rich! Come on!!"

Byron, "How many!?"

Sam, "Say it is enough!"

Looking over there, "However, you have to hurry up, Academician Nan may get some points."

Byron, "Beautiful thinking!"

He went to Qi Lei, and jumped on him.

"You're back! How much money did you bring?"

Qi Lei, "..."

You've all lost your money, haven't you?

"Don't worry, it's enough for you to squander!"

Byron, "Really?"

"real!"

"FUCK!!" Byron spat, "I really saw the right person!"

As he spoke, he yelled at Zhuo Zhuo: "Xiao Zheng, go to the filing cabinet in my office and get them all over!"

Qi Lei, "???"

But Byron forcibly pressed him on the chair, and in front of him was an additional procurement report, an academic report on the production process of monocrystalline silicon.

"We said before, start with the wafer, right?"

Qi Lei nodded, "Yes!" He frowned, "You're done?"

That Byron is really fast enough.

As a result, Byron pretended, "You're an amateur, aren't you?"

"With this technology, there is no problem of getting it done or not, but it depends on the size you want."

"If you want to say two inches, don't use technology, I will rub it out for you manually."

"The four-inch and six-inch ones don't need to be researched, you can just throw them into the factory."

"The eight-inch is the current mainstream, and it is also my primary public relations direction. The twelve-inch is the future. If it is made, it will be the only one in the world!"

Qi Lei, "..."

Too professional, listening to a headache, "Just tell me, where have you gotten!"

Byron opened the report and pushed it in front of Qi Lei, "The eight-inch wafer was manufactured, and the theoretical construction of the process was done one and a half months ago."

Qi Lei, "!!!"

Byron, "Twelve inches, let's wait until eight inches are produced!"

Qi Lei's eyeballs are about to pop out, what a good thing!

Ox! !That's awesome!

"Then you make it!"

Byron shook his head, "It can't be made."

"What?"

"If you don't buy me production equipment, how can I make a fart? There is no way to actually verify it!"

Qi Lei rolled his eyes, "What's the big deal!? Buy it! I'll give you the money!"

Byron was waiting for this sentence, and pushed the purchase report over with a swipe.

"Then sign and pay!"

Qi Lei was very happy, opened the purchase report, picked up a pen and was about to sign it.

"how much is it?"

Byron said, "Not much, 4 to 5 million dollars!"

"puff!!"

Qi Lei came out with a mouthful of old blood, "Then more than 40 billion RMB?"

You prodigal stuff, is it too expensive?

……

Chapter 533 Up?

More than 40 billion?This money is not worth spending!

"Then what..." Qi Lei cleared his throat, "Did you spend so much money? You don't want to build a factory directly, do you?"

When Byron heard this, he quickly waved his hands, "No, no! How can we build a factory with more than four billion yuan? It's a production line for experimental demonstration."

Spreading your hands, "There is no manufacturer of silicon wafers in China. We can't cooperate with manufacturers to verify the process. We can only build a production line for experimental processes!"

Qi Lei: "..."

It's a bit expensive!

Bai Lun also noticed that Qi Lei was a little hypocritical, and hurriedly said: "Don't worry, this thing is not wasted, and it can be used all the time in the future. Even if our silicon wafer process is mature, and there is no need for process verification, we can directly change it into production." use."

"Oh." Qi Lei breathed a sigh of relief, if you say that, I really feel relieved.

He was really afraid that Byron would need several billions for an experiment, and tens of billions more for it to be put into production in the future.

What the hell, I really can't afford it!

……

……

The so-called monocrystalline silicon, that is, the production of wafers, in fact, speaking of this stuff, it couldn't be simpler.

First of all, polycrystalline silicon and monocrystalline silicon are the same substance in the chemical sense - silicon element.

Silicon is also the main component of common sand and quartz stone in nature.So people often say that chips are made of sand, which makes sense.

As for the difference between polycrystalline silicon and monocrystalline silicon?

You can imagine the internal structure of polysilicon as a box of scattered matches, stacked on top of each other, it is disorganized.

Such an internal structure cannot be used in the field of chips with nanoscale as the unit of manufacture.A negligible internal void, or even a messy arrangement of atoms, can affect the performance of a chip.

Therefore, the silicon element used to make chips must be rearranged.Let the matches be arranged regularly, just like in a matchbox.

This is monocrystalline silicon.

And this process from messy to continuous, that is, the manufacturing process of wafers, is complicated.

At present, the method commonly used in the world for the preparation of single crystal silicon is called the Tchaikrasky method.

It is to heat polysilicon to a molten state. To put it bluntly, it is a basin of magma.

Then, put a single crystal silicon seed into the molten liquid, let the liquid silicon attach to the seed and recrystallize, and slowly "grow" into a larger single crystal.

In this "growth" process, by controlling the rotation speed of the seeds and the speed at which the seeds are pulled out of the molten liquid, a cylindrical single crystal silicon will be obtained.

After that, it is simple, slice and polish the single crystal silicon pillar, and it is a wafer.Chips are etched on such single silicon discs one by one.

It sounds like it's not difficult, right?

In fact, it is already very difficult, if anything is done to the extreme, then nothing is not difficult.

First of all, in order to obtain high-purity polysilicon, it is necessary to refine silicon dioxide, that is, sand and quartz, through a series of steps such as electric arc furnace refining, hydrochloric acid chlorination, and distillation purification.

How much high-purity polysilicon must be obtained in order to meet the requirements?

Take Byron as an example. He is a bigwig in this field. If the purity is low, it definitely does not meet his status, but if it is too high, it is unrealistic. Let’s let it be the average level of the industry!

Then, the purity of polysilicon needs to reach 99.9...9%, nine nines after the decimal point.

In this process, the preparation of polysilicon, the precision of the equipment, the dust-free environment, the stretching process, etc., every step must be done to the extreme.
