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

"Then what..." Qi Lei cleared his throat, "Do you spend so much money? Are you going to build a factory directly?"

When Byron heard this, he quickly waved his hand, "No, no! How much more than 4 billion to build a factory? It's a production line for experimental demonstration."

Yi Tan said, "There is no manufacturer of silicon wafers in China. We can't cooperate with manufacturers to verify the process flow. We can only build a production line for the experimental process!"

Qi Lei: "..."

It's a bit expensive!

Byron also saw it, Qi Lei was a little false, and quickly said: "Don't worry, this thing is not wasted, it can be used all the time in the future. Even if our silicon circle process is mature and no process verification is required, it can be directly changed to production. use."

"Oh." Qi Lei breathed a sigh of relief. If you said that, I would really feel relieved.

He was really afraid. Byron's experiment would cost several tens of billions. If it can be put into production in the future, it will cost tens of billions more.

That's so special, I really can't afford it!

——————

The so-called monocrystalline silicon is also called wafer production. In fact, this thing can't be simpler.

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

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

As for the difference between polysilicon and monocrystalline silicon?

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

Such an internal structure is useless in the field of chips made of nanoscale units. A trivial internal void, or even a clutter in the arrangement of atoms, can affect the performance of the chip.

Therefore, the silicon element for making chips must be rearranged. Make a regular arrangement of matches from match to match, as neat as 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 commonly used method for preparing single crystal silicon in the world is called the Tchaikolaski method.

It is to heat polycrystalline silicon to a molten state, or to put it bluntly, it is a pot of magma.

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

In this "growth" process, controlling the rotation speed of the seeds and the speed at which the seeds are pulled out of the melt will result in a cylindrical monocrystalline silicon.

After that, it's simple. Slice and polish the single crystal silicon column, which is a wafer. The chip is etched on such a single silicon disc.

Sounds like it's not difficult, doesn't it?

In fact, it is already very difficult. If you do anything to the extreme, it is not difficult.

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

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

Take Byron as an example. He is a big man in this field. If the purity is low, it definitely does not fit his status, but if it is too high, it is unrealistic, so let's say it is the industry average!

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

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

And, that's not all, the most difficult thing is actually to control the diameter of the silicon circle.

How to make the diameter of the silicon circle large enough is the key.

That is, the thicker the better.

Because the chips made later are square, and the single crystal silicon made by the Tchaikovsky method can only be round.

This is equivalent to drawing squares one by one on the disc, and there must be areas on the edge that cannot be drawn square, so it is wasted.

Then the problem is, if I use a silicon circle with a diameter of one inch, I may draw a few squares, or a dozen squares, and I can't draw any more. It is assumed that 30% of the edge area is wasted.

But I use an 8-inch silicon circle, which can draw more squares on a circle, and maybe only 10% of the wasted area.

And so on, 12-inch...

The thicker the wafer, the more squares are drawn, and the smaller the proportion of wasted area.

Less waste means lower chip cost.

Therefore, the manufacture of single crystal silicon has two cores:

First, purity.

Second, make the wafer as coarse as possible.

Who can make these two technologies run ahead, then whoever can lead the world.

Byron has done in-depth research in this area. The experimental production line he is going to work on now is the production line for large-diameter monocrystalline silicon.

Among them, the core equipment does not need to be thought about, all are imported.

Moreover, it's not cheap, any part of the equipment is tens of millions, or even hundreds of millions.

"Actually, it's not that expensive."

At this time, Byron said, "If we purchase this set of equipment as an American company, a few hundred million will be enough."

"pity!"

The implication is that we are Chinese, who won't they knock you on the baton?

"And!!" Byron looked solemn, "I'll tell you the truth, even if it's sold to us, it still needs to be said if it can be used."

"Huh?" Qi Lei frowned, "What do you mean?"

Byron spread his hands, "Because this is a trap!"

Qi Lei, "..."

Byron, "The ones that can be listed are those with low technical content or weak patent barriers. We can find alternatives, or we can spend a little time on our own research."

"And some of the core components and key materials, you can't buy them with money, and they are absolutely embargoed to you."

Qi Lei, "..."

At this time, Nan Lao replied, "To put it bluntly, their plan is to make you spend billions to buy back a pile of scrap iron, and you can't make a single wafer!"

Byron, "So, for the remaining part, we can only find a way to cooperate with other domestic research institutes and high-precision component companies. How much this part will cost, it is hard to say."

Nan Lao also said to Byron at this time, "It's not that Byron is a prodigal, there is really no way. Unless you can get those embargoed parts back through foreign channels!"

Qi Lei frowned and was about to talk, but Byron took the lead, "If you don't spend the unjust money, we'll do it ourselves!"

Qi Lei raised his head and met Byron's fire-breathing eyes.

"Qi!! The guarantee I can give you is that as long as your money is in place, I can make things for you!"

"If you can't make it, I, Byron August, will put my head on you!"

"I don't believe it anymore. Without them, we wouldn't be able to live!!"

Don't look at Byron being mean and stupid, but that doesn't mean he's not angry.

I have never felt this kind of anger!

This sentence, obviously a little angry, is enough to represent his mood.

Qi Lei stared at him for a long time.

With a sullen head, he picked up the pen and signed directly.

While signing, he asked, "How much are the core components and materials?"

Byron raised his eyebrows, "One billion?"

Qi Lei, "Is it enough?"

Byron, "Enough!!"

Over there, Nan Lao couldn't hold back and slammed the table, "If you start from scratch, it's only one billion? What's this called!?"

Qi Lei didn't hear it, he turned his head down and signed his name one by one, "Bring it here!"

Byron was startled, "What?"

"Report!"

Byron still didn't understand, "What report?"

But it was assistant Xiao Zheng who understood immediately, took out a copy from a pile of reports, and shoved it in front of Qi Lei.

"This, this is a report on the missing parts of the wafer production line."

He was a little weak, and was suppressed by Qi Lei's aura, "I haven't done accounting yet. Also, I haven't contacted other companies!"

Qi Lei didn't care, he took it directly, took a quick look, and signed.

Still bowing his head, "I'll reserve 1.5 billion for you for this part, which will be credited to the Institute soon."

Suddenly looking up at Byron, "I don't want your head, just a word from you. If you say it's feasible, I'll give you the money!"

Looking up at the scholars and experts, "This will be the rule in the future. As long as the theoretical verification has passed, as long as you feel it is necessary, then report it immediately, and the funds will definitely go ahead of your research!"

Byron, "..."

Guys, "..."

A bit domineering! Domineering to the point that it doesn't look like Qi Lei anymore.

Nan Lao and Sam frowned and wondered, why is there such a big resentment? In the past, Qi Lei was very flexible.

It's just, how do they know that Qi Lei has been very angry in the past few months abroad.

I want to join the Electronics Industry Association, but you won't let me. Row! It's yours, you hide, tuck, and protect. I understand, I endure it!

Now, I'm home, don't let me use it, I'll build the head office myself, right?

But it still won't work, even a single screw will block you.

also! !

I can bear it, who made us not even have a screw!

Then I can spend money, okay?

I have money!

Qi Lei was also angry, but he didn't show it easily.

"Is there any more?" Qi Lei looked at everyone, he came to the Magic Capital just to throw money, "If you have it, bring it up together!"

These words...

These words made everyone stunned.

Byron looked at Nan Lao, Nan Lao looked at everyone, and everyone looked at Sam.

Sam thought to himself, but? That's 5.5 billion thrown out, and it's beyond Sam's expectations.

Seeing that Byron was a little bit up, he was eager to try, and hurriedly stopped, "For the time being... Enough!"

That's not how money is spent.

As a result, Nan Lao and Byron suddenly said, "Actually, there is a project that needs to be considered now."

Sam rolled his eyes, you guys are really welcome.

And Qi Lei was even more surprising, "What project? Is it necessary?"

This time, Nan Lao and Byron almost said in unison, "Yes!! And we also need technical public relations. We must act first, otherwise it may be troublesome in the future!"

"what?"

Byron, "Build a water purification plant."

"Uh……"

Qi Lei was embarrassed, a water purification plant? this thing...

Well, since you asked for it, is it important?

Besides, how much money a water purification plant can spend is nothing compared to these projects that are worth hundreds of millions or billions of dollars.

"establish!"

Byron, "The initial investment is more than one billion."

Qi Lei, "Wait a minute!"

The whole person is not well, it's just a water plant, and it costs more than one billion?

Staring at him, "I'll give you another Coke production line. You can compete with Coca-Cola."

Is this too much? One billion?

When Byron heard this, he looked disgusted, "What do you know?"

"I'm not kidding you, water purification is a must! Otherwise, you won't be able to process silicon wafers or make chips yourself, including other projects."

"Don't think about it all!"

Qi Lei, "..."

Over there, Nan Lao smiled bitterly, "Indeed, there must be!"

……

Qi Lei didn't know, or rather, his understanding of high-end manufacturing was not systematic.

There is a real need for water, and it is not a general demand, but a huge amount of water resources.

Nan Lao explained, "No matter which direction we go or where we want to make a breakthrough, we need water, a lot of water!"

He gestured to Qi Lei, "For high-end electronics manufacturing, because it is a microscopic process, to a certain extent, the highest pursuit is precision."

"Take chip manufacturing as an example. Normally, there are more than 100 processes, and a considerable part of them need to be washed with water."

Qi Lei opened his mouth wide, his eyes rolled, Nan Lao repeatedly emphasized a lot, what do you mean? Do you use a lot of water?

"How much water do you use?"

Nan Lao lowered his head and pondered for a while, "Let's put it this way, a company of TSMC's size has already brought its craftsmanship to the extreme, but it takes about 30 pounds of water to manufacture a 130-nanometer chip. Let's start from scratch. , only more than that."

"From the current point of view, it is possible to use at least about 10,000 tons of processing per day, not counting future expansion."

Qi Lei, "..."

Byron said at this time, "You must build this water purification system. If you can't save it, you will have to invest it sooner or later!" A little embarrassed, "Also, it is matched with the experimental production of silicon circles. Without it, silicon circles would not be possible. Can't work."

Qi Lei understood, meaning that if you don't vote for these billions, then the 5.5 billion before that is also a waste of money?

I wondered if I could find a replacement or something. Of course, tap water certainly won't do. If it was possible, these prodigal old men would not make this request.

However, in his later generations, he heard that it can be used directly in Whaha's purified water laboratory, and the purity is very high.

Then, can I pack the water thing out?

She didn't dare to show her timidity, so she asked tentatively, "Is there a substitute?"

"For example, let's work with W Haha?"

"Haha..." As a result, all the experts in the room laughed.

Byron said speechlessly, "The water we are going to use is 1,000 times as pure as ordinary tap water. It is called ultrapure water!"

"No haha!"

"Okay!" Qi Lei gave up ~www.wuxiaspot.com~ and prepared to sign.

However, as soon as he saw more than one billion yuan, he felt a pain in the ass. Isn't that how I spend money when I have money?

He hesitated again, "It's just a set of water purification equipment. Does it cost more than one billion? Is it too much?"

Nan Lao heard it, "There is no way, we don't have the ability to produce ultra-pure water in our country."

Qi Lei, "Understood, import?"

Everyone nodded in unison: "Yes!"

Qi Lei gritted his teeth, "Approved!"

Hearing that, Sam grinned, how much money does Qi Lei have?

He hurriedly added, "This can be slowed down for a while. It's not too late to invest again in a year and a half. You don't need to prepare funds."

However, Qi Lei shook his head, "The money will arrive soon! I have one request, don't hold back."

Sam, "..."

Sam felt that Qi Lei was a little over the top?

This is not a good thing!
