Homecoming of Rebirth

Moreover, this is not counted, 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 produced later are square, and the monocrystalline silicon produced by the Tchaikrasky 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 where the squares cannot be drawn, and they will be wasted.

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

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

By analogy, the 12-inch...

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

Less waste means lower chip costs.

Therefore, the manufacturing of monocrystalline silicon has two cores:

First, purity.

Second, make the wafer as thick as possible.

Whoever can make these two crafts go to the front will be able to lead the world.

Byron has conducted in-depth research in this area, and the experimental production line he is going to use now is the production line for large-diameter monocrystalline silicon.

Among them, there is no need to think about the core equipment, all of which are imported.

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

"Actually, it's not that expensive."

At this moment, Byron said, "If we purchased this set of equipment as an American company, a few hundred million would be enough."

"pity!"

The implication is that we are Chinese, who else will they bully if they don’t trick you?

"And!!" Byron looked serious, "I'll tell you the truth, even if it's sold to us, we still have to talk about whether 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 on the list are not high-tech or have 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 for you."

Qi Lei, "..."

At this moment, Mr. Nan answered, "To put it bluntly, their plan is to let you spend billions of dollars to buy back a pile of scrap iron, and even a single wafer cannot be produced!"

Byron, "So, the remaining part can only be developed by ourselves and cooperate with other domestic research institutes and high-precision component companies. It's hard to say how much this part will cost."

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

Qi Lei frowned, and just about to start a conversation, it was Byron who took the first step, "Don't waste the money, let's 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 you have the money in place, I can build things for you!"

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

"I still don't believe it, we can't live without them!!"

Don't look at Byron's vicious mouth and stupid heart, but that doesn't mean he has no anger.

I've never been so angry!

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

Qi Lei stared blankly at him for a long time, didn't say anything, his teeth were about to be gritted, what the hell?

Dumbly picked up the pen and signed directly.

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

Byron raised his eyebrows, "One billion?"

Qi Lei, "Is that enough?"

Byron, "Enough!"

Over there, Mr. Nan couldn't hold back, and slammed the table, "From the beginning, it's only one billion? What's this called!?"

Qi Lei didn't hear it, he lowered his head and turned the pages, signing his name one by one, "Bring it!"

Byron was taken aback, "What did you bring?"

"report!"

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

It was the assistant Xiao Zheng who suddenly understood, dug out a copy from a pile of reports, and stuffed it in front of Qi Lei.

"This, this is a report on the shortage of vital parts in the wafer production line."

A little weak, also suppressed by Qi Lei's aura, "I... haven't done the calculation yet. Also, I haven't contacted other companies either!"

Qi Lei didn't care, just took it over, took a quick look, and signed.

Still lowering his head, "I will reserve 15 billion for you, and it will be transferred to the institute's account soon."

He looked up at Byron suddenly, "I don't want your head, I just want you to say something. If you say it's feasible, I'll give you money!"

Looking up at a group of scholars and experts, "This will be the rule from now on. As long as you have passed the theoretical verification, as long as you think it is necessary, then report it immediately, and the funding will definitely be ahead of your research!"

Byron, "..."

Everyone, "..."

A bit domineering ha!He is so domineering that he doesn't look like Qi Lei anymore.

Old Nan and Sam frowned and wondered, why are they so resentful?In the past, Qi Lei was very flexible.

It's just that they didn't know that Qi Lei had been so pissed when he was abroad for the past few months.

I want to join the Electronics Industry Association, but you won't let me.OK!It's your thing, you hide it, you tuck it in, you protect it.I understand, I endured it!

Now that I'm home, it won't be used by me. I'll build the head office myself, right?

But it still doesn't work, a screw will jam you.

also! !

It can be tolerated, who told us that we don't even have a screw!

Then I spend money, right?

I have plenty of money!

Qi Lei is also angry, but he doesn't show it easily.

"Is there any more?" Qi Lei looked at everyone, he came to Shanghai to throw money, "If you have any, let's bring them together!"

This word...

This question stunned everyone.

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

Sam thought, but that's it?This has thrown out 55 billion, which has exceeded Sam's expectations.

Seeing that Byron was a little bit on top, he was eager to try, and hurriedly stopped, "For the time being... that's enough!"

That's not how money is spent.

In the end, Mr. Nan and Byron suddenly said, "Actually, there is a project that needs to be considered now."

Sam rolled his eyes, you are so welcome.

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

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

"what?"

Byron, "Build a water purification plant."

"Uh……"

Qi Lei was embarrassed, water purification plant?This thing...

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

Besides, how much a water purification plant can cost is nothing compared to these billion-dollar or billion-dollar projects.

"establish!"

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

Qi Lei, "Wait a minute!"

The whole person is not good, and the water plant is just more than a billion?

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

Is this too much?More than one billion?

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

"I'm not joking with you, water purification is a must! Otherwise, you will not be able to process silicon wafers, make chips yourself, and other projects."

"Don't even think about it!"

Qi Lei, "..."

Over there, Old Nan smiled wryly, "Indeed, there must be!"

……

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

Water is really needed, and it is not just a general need, but a huge amount of water resources.

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

He gestured to Qi Lei, "High-end electronics manufacturing, because it is a micro-craft, so, 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 needs to be washed."

Qi Lei opened his mouth wide, rolled his eyes, 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 bowed his head and pondered for a while, "Let's put it this way, a company of TSMC's size has already brought its technological level to the extreme, but it needs to consume about 130 catties of water to manufacture a 30-nanometer chip. Let's start from scratch." , only more than that."

"According to the current situation, at least about 1 tons of daily processing is required before it can be used, not counting future expansion."

Qi Lei, "..."

Byron said at this time, "You have to build this water purification system, you can't save it, you have to invest in it sooner or later!" I was a little embarrassed, "Besides, it is matched with the experimental production of silicon circles. Without it, silicon circles will not Can't work."

Qi Lei understood, what it means is, if you don't invest this billion, then the previous 55 billion is also worthless?

Wondering if I could find a replacement.Of course, tap water will definitely not work.If it is possible, these prodigal old men will not make this request.

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

Then, can I take care of the water use?

Not daring to show timidity, he asked tentatively, "Is there... a substitute?"

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

"Haha..." In the end, all the experts in the room laughed.

Byron was speechless: "The water we are going to use is 1000 times purer than ordinary tap water. It is called ultrapure water!"

"No haha!"

"Okay!" Qi Lei gave up and prepared to sign.
