Technological power starts with upgrading lenses

Chapter 37
Although semiconductor-grade monocrystalline silicon is only one grade behind photovoltaic-grade monocrystalline silicon, its purity has increased by five nines.

光伏级单晶硅的纯度是99.999999%，后面有6个9，但半导体级单晶硅却需要11个9。

With the improvement of purity, the requirements for factory equipment and control accuracy have suddenly increased by an unknown number of times.

The purification of semiconductor-grade monocrystalline silicon is only the first step in silicon wafer manufacturing. Subsequent equipment for chamfering, cutting, chemical mechanical polishing, etc. basically all relies on imports.

Because the market size of silicon wafers is not large, with only more than 100 billion US dollars globally, it has not been the focus of domestic semiconductor research from the beginning.

Mainly to concentrate on doing big things,

We can only selectively abandon certain links and markets.

This makes the current global silicon wafer market basically occupied by the island country's Shin-Etsu Chemical and S&G Group.

The two of them alone have taken away 58% of the global market share.
The rest were divided up by Treasure Island, Hans Country, and Bangzi.

Mainland China's silicon wafer manufacturing capacity can basically be said to be blank.

At a time when the trend of anti-globalization is becoming more and more obvious,

This is actually very dangerous.

Now Eagle Sauce only restricts chip manufacturing equipment.
But if he asks a few more of his younger brothers to stop supplying silicon wafers to China,
Even if we conquer the lithography machine, we will still be in a dilemma without silicon wafers to engrave.

In fact, in recent years, the country has begun to realize this problem.
And began to make efforts to try to open up this most upstream link,
But because this is a high-investment, low-return thing, progress is slow.

At present, the silicon wafers produced in China are mainly 8 inches, and the large 12-inch silicon wafers basically rely on imports.

Although there are a few companies that can manufacture 12-inch silicon wafers, due to technical and equipment reasons, the yield rate is very low, they have been in a state of loss, and they dare not expand production at all.

But for the systematic Kangchi, this is a good choice.

Low investment, medium return, it is an industry he can obtain.

At the same time, it can also be regarded as his ticket to enter the semiconductor industry.

You can’t just build a 14nm lithography machine as soon as it comes up, right?
Let’s not talk about funding issues first.

Countless scientific researchers have worked hard day and night and still haven't conquered it, but a person appears out of nowhere and picks the peaches.
Who can bear this?
Give them some face and buffer time.

So it’s up to me to gnaw on the hard nut of silicon wafers!
Semiconductor grade monocrystalline silicon smelting analysis, consuming 5 mastery points!

As Kang Chi pressed the option, a large amount of knowledge rushed into his brain crazily.

Huh?
Why is it not as painful as imagined?
Kang Chi frowned in confusion.
The last time I analyzed the lens process, it was much more painful than when I analyzed the lens.

Logically speaking, the amount of information analyzed this time should be no less than that of analyzing lenses.

Kang Chi was already prepared to be in pain for a few minutes.

But unexpectedly, after only three seconds, the pain disappeared!
At the same time, he was also surprised to find that the knowledge analyzed this time was also deeply integrated with the knowledge theory he had learned during this period.
It feels like learning a bunch of theories and then carrying out countless practices.

It feels like everything comes naturally and everything is integrated.

Kang Chi couldn't help but be a little surprised,

I didn’t expect that learning theoretical knowledge in advance can have such an effect?
With theory + practice, Kang Chi now feels like a real expert in monocrystalline silicon smelting.
He is familiar with all the difficulties and solutions in smelting, and he also fully understands the design and principles of single crystal furnaces.

This is too cool!

Kang Chi spent more than ten minutes slowly reviewing the knowledge in his mind, and then continued to analyze it with great anticipation.

Analysis of chamfering process,

Spend 5 mastery points!

Multi-wire cutting process analysis, consumption of 10 mastery points!

Chemical mechanical polishing process analysis,

Spend 10 mastery points!

After spending 30 proficiency points, Kangchi has completely mastered all the production processes of 12-inch silicon wafers, as well as equipment manufacturing technology.

Now, he is no longer afraid of anyone asking questions about silicon wafer manufacturing.

Even the best researchers or engineers at Shin-Etsu Chemical would definitely not be able to integrate theory and practice like him and understand silicon wafers so thoroughly.

Finally, everything is ready, all we need is the east wind!
In order to pave the way for the next plan, Kang Chi turned on the computer and started writing the paper.

At the same time, he also contacted a lawyer who specialized in patent matters and started to apply for several important patents.

Once the patent application is approved, you can start submitting papers.

At the same time, in the Blue Lake Resort in Dongyang City, two men were sitting on deck chairs and smoking cigarettes.

The man sitting on the left wears sunglasses, his hair is slicked back in a literary style, and he only wears a thin blue suit, which makes him look a little fresh.

But the wrinkles at the corners of his eyes betrayed his age, which was no less than 40 years old.

While puffing away his smoke, he kept looking at the children playing on the lawn. It wasn't until he put out his cigarette that he turned to the fat middle-aged man next to him and said:

"I heard that the city intends to create a separate high-tech zone next to the development zone?"

"Mr. Deng is so well-informed?" The fat middle-aged man narrowed his eyes slightly, "I just found out about this in the morning."

"Are there any preferential policies?"

"The land price is 50% of the normal market price, half sold and half given away, tax-free for three years, and after three years it is charged at the normal 15% rate for high-tech enterprises, but the premise is that the investment scale is at least [-] million."

"Well, the policy is very good. Does Director Wang think our Hengxing Group is qualified to get a piece of it?"

"Well...it depends on what name you use. If it's just your previous business, it definitely won't work. But if you set up a subsidiary company and turn it into a high-tech enterprise, the problem will be solved."

Director Wang said, and looked at Deng Xing meaningfully,
"The biggest problem is the investment of at least [-] million yuan... I heard that this review is stricter. The authorities will not let the rabbit go before it is released, and the project will not be approved until the money is in place. Moreover, the project must be launched within half a year, otherwise it will be under supervision." You can’t even take away any money in the account.”

After hearing this, Deng Xing frowned.

"Can't you be accommodating?"

Director Wang shook his head: "This is not something I can decide. I am only responsible for processing the application. The specific decision is made by our Bureau Guo."

When Guo Bureau was mentioned, Deng Xing felt a toothache.

After a moment of silence, he asked unwillingly: "Is there any other way?"

"There is a way you can try, but it may not work."

"Oh? Tell me?"

"It's very simple. This high-tech zone has just started to be developed. The city has good ideas and thinks this is a huge success, so it dares to set such high requirements."

"But in fact, after everyone sees such stringent requirements, it is still unknown whether any companies will respond. Once the delicious cakes are given out and no one wants to taste them, will the requirements have to be lowered?"

Deng Xing's eyes lit up after hearing this, and he said with a smile: "Director Wang has the experience. You are responsible for reviewing the application. As long as you delay here, no one can take away this sweet and sour cake. Don't worry, after everything is done, It’s still the same old rules.”

"Hey, look at what Mr. Deng said, what does delaying mean?" Director Wang said with a serious face, "I am just a small clerk, I can only act in accordance with the normal rules and regulations. It's not me who has the final say whether it's okay or not, it's the regulations. The final word!"

"Hey, yes! Director Wang is right. I made a mistake in my expression. Don't take it to heart..."

Deng Xing quickly poured a cup of tea to moisten his throat as an apology...
