***********
"Really?" Pop!The kettle in Peng Aidang's hand fell to the ground, not only spilled all over the floor, but also spilled a lot on Peng Aidang's shoes and trouser legs, but Peng Aidang didn't care, just stared at Tianze scorchingly.

Why did Peng Aidang have such a big reaction?
All because of the pain in my heart.

Think about it!

A great country with a history of 5000 years, but it can't even make a decent chip.

How sad is this?

And what is the basis for making chips?
It is the wafer and the lithography machine.

To use an analogy, if you use building blocks to describe the manufacture of chips, then the wafer is a piece of building blocks, and the lithography machine is the hand that builds the building blocks.As for what the building blocks look like, it depends on what kind of chip the chip designer can design.

而大家平时听到的18寸晶圆厂、12寸晶圆厂、8寸晶圆厂，其实就是分别指300mm、200mm、150mm的晶圆。再说通俗点，电脑中的cpu其实就是一块雕刻好的晶圆，大多数都是12寸的。

As for why the wafer is getting smaller and smaller?

First, in order to save space on the circuit board, large-scale and ultra-large-scale integrated circuits will only be possible if each component is very small.If the integrated circuit is made very large, and each component in it is as large as a discrete component, there will be no mobile phones today, and a 10G USB flash drive will be as large as a car.

Second, in order to save power consumption, the smaller the components, the less power consumption is required.

The third is to save raw material consumption and improve production efficiency.

And what is the status of wafer production in Huaguo?
Just look at the data.

Shin-Etsu and Sumco in Japan, LGSiltron in South Korea, Siltronic in Germany and Global Wafers in Wanwan, these wafer manufacturers account for as high as 98%. This is a highly monopolized market, especially among large Partly controlled by our neighbors Waguo and Bangzi.

Huaguo can only share the remaining 2% (with other countries in the world).

Just think about how miserable it is.

Why is it so miserable?

First, the process of producing silicon wafers is like making cotton candy, spinning and forming.In the process of pulling the crystal, the speed of spinning and pulling up and the temperature control will affect the quality of the wafer.Such a high technical difficulty is a huge challenge for Huaguo Semiconductor, which has a relatively weak foundation.

Second, patent protection.

The manufacturing process of semiconductor silicon has been developed by countries such as Japan, Japan, Germany, and the United States since it appeared in the 50s. They have accumulated rich experience and patents in the manufacture of silicon wafers. This is not Huaguoneng. easily broken through.

Not to mention the photolithography machine.

How silicon wafers become integrated circuits depends entirely on lithography machines.

To put it simply, the function of a lithography machine is to carve out individual circuits on the wafer, and the 10nm-level lithography machine means that the minimum line can be 10nm.So what is the concept of 1nm?Use the thickness of the nail cover as a comparison, that is to say, try to cut the side of a piece of nail into 10 lines, and each line is equivalent to 1 nanometer. From this, you can imagine how small 1 nanometer is, right?

Like wafer production, lithography machines are also monopolized by foreign manufacturers.

The most famous ones are ASML in the Netherlands, Nikon and Canon in Japan, and Huaguo can only spin on the edge of low-end lithography machines.According to the normal situation, if there is not a few decades, don't even think about catching up. As for overtaking, it is a dream.

"Very true."

Tian Ze smiled and nodded, "And it's a brand new technology, so you don't have to worry about patent issues at all."

Just kidding, if not for a whole new craft.

Tianze would not waste the ps system's deduction opportunity at all, but let the Jade Emperor steal it directly.

"What are your conditions?"

After taking a few deep breaths, Peng Aidang picked up the kettle and asked.

"First, let Lin Fei and the others leave." Tian Ze said again.

"That's fine."

Peng Aidang nodded without thinking this time.

This is the latest wafer and lithography machine production technology!Compared with letting Lin Fei and others go, there is no need to think about it at all, and it is not at the same level at all, and it cannot be regarded as a condition at all.

In one sentence, absolutely no one will raise objections.

As for Lin Fei's feelings?
Hehe, when he dared to threaten Tian Huaien and Tang Xiuxiu, he was already doomed.

"Second, all factories that use my technology must give me 15% of the shares." Tianze continued.

"End?"

Peng Aidang looked surprised.

Is 15% stake too much?Not too much, worth the price.

In Peng Aidang's view, this condition is simply too generous.Even if Tianze proposes to take half of the shares, the country may agree, but it cannot be given for nothing, and a large amount of money must be invested.

"Well, just these two points."

Tian Ze affirmed.

Tianze is naturally not stupid, but has his own plans.

Whether it is wafer production or lithography machine production, they are all known as gold-swallowing beasts.

A wafer factory with a monthly output of RMB [-] would cost tens of billions of dollars in investment.

Not to mention the lithography machine.

A 10nm-level lithography machine can cost more than 7000 million US dollars alone, so how much is its research and development cost?At least 100 billion, or US dollars.Therefore, the construction of fabs and lithography machine factories is completely burning money. It is better to leave this kind of matter to the state. Anyway, Tianze owns shares, so it is not afraid of not being able to get the goods.

Just sit back and enjoy it.

What Tianze wants to set up is a chip manufacturing company, like Qualcomm and Intel.

This is also the reason why Tianze did not hand over 7nm chips.

Good things should naturally be kept for themselves.

When the country can produce qualified wafers and 7nm-level lithography machines, that is the moment when Tianze Chip Company was established.Hehe, it's not that Tianze is insidious. Speaking of which, Tianze is completely helping his country. The country has broken the technological blockade of Europe and the United States, and Tianze has also made money.

Isn't it the best of both worlds?
"Okay, okay, I really didn't misread you." Peng Aidang said with relief.

"That's right, you're an old revolutionary, how could you be mistaken?" Tian Ze patted the horse casually.

"You boy, haha!"

Peng Aidang was overjoyed.

"Yo, it turned out that it was Xiaotian who came. I said why Dad would be so happy. Xiaotian, you haven't come for a while. My dad couldn't find someone to play chess with. You see, when you come, you will kill me." Dad is happy, you must come here often in the future! Otherwise, don’t blame me for sending someone to arrest you.” It happened that Peng Weiguo came back with Gao Xiaoqiang.

"Okay, I must come often."

Seeing that Peng Weiguo misunderstood, Tianze did not explain.

The production technology of wafers and photolithography machines are all top secrets.

The less people know, the better. As for whether Peng Ai's party will tell Peng Weiguo, that's none of Tianze's business.

"Come on, let's go into the house and talk."

Peng Weiguo waved to Tianze.

"Okay!"

Tian Ze said happily.

No need to guess, Tianze also knew that Peng Weiguo wanted to talk about the car factory, and it had been more than a month since the construction started in February.With Tianze's investment regardless of cost, the construction speed of the automobile factory is very fast. There are as many as ten factory buildings completed, and many equipments have been debugged, and a small amount of production can be put into production soon.

Can Peng Weiguo not care?
