Chapter 37 A natural outcome
Although semiconductor-grade monocrystalline silicon is only one level lower than photovoltaic-grade monocrystalline silicon, its purity has increased by 5 nines.
The purity of photovoltaic-grade monocrystalline silicon is 99.999999%, with 6 nines behind it, but semiconductor-grade monocrystalline silicon requires 11 nines.
The improvement in purity has suddenly increased the requirements for plant equipment and control accuracy by an unknown number of times.
The purification of semiconductor-grade monocrystalline silicon is only the first link in silicon wafer manufacturing. There are also equipment for chamfering, cutting, chemical mechanical polishing and other links in the follow-up, which are basically all dependent on imports.
Because the market size of silicon wafers is not large, with only more than 10 billion US dollars worldwide, it has not been the focus of domestic semiconductor research from the beginning.
It is mainly to concentrate on major tasks.
It can only selectively give up certain links and markets.
This makes the global silicon wafer market basically occupied by Shin-Etsu Chemical and Shenggao Group of the island country.
These two companies alone have taken away 58% of the global market share, and the rest has been divided up by Taiwan, Hans, and Bangzi.
China’s silicon wafer manufacturing capacity can basically be said to be blank.
At a time when the trend of deglobalization is becoming more and more obvious,
This is actually very dangerous.
Now the Eagle Sauce is only restricting chip manufacturing equipment, but if he lets a few brothers stop supplying silicon wafers to China, then even if we conquer the lithography machine, we will fall into the dilemma of having no silicon wafers to carve.
In fact, the country has begun to realize this problem in recent years, and has begun to work hard to try to open up this upstream link, but because it is a high-input, low-return thing, progress is very slow.
At present, the silicon wafers produced in China are mainly 8 inches, and the 12-inch large silicon wafers are basically dependent on imports.
Although a few companies can make 12-inch silicon wafers, due to technical and equipment reasons, the yield rate is very low, and they have been in a loss-making state, and dare not expand production at all.
However, for Kang Chi, who has a system, this is a good choice.
Low investment, medium return, an industry that he can get.
At the same time, it is also his ticket to enter the semiconductor industry.
You can’t just make a 14-nanometer lithography machine right away, right? Let’s not talk about the funding issue first.
Countless scientific researchers have worked hard day and night to study and have not yet conquered it, but a person who came out of nowhere picked the peach right away. Who can bear this? Give them some face and buffer time.
So I’ll have to chew on this hard bone of silicon wafers! Analysis of semiconductor-grade single crystal silicon smelting, consumes 5 mastery points!
As Kang Chi pressed the option, a lot of knowledge poured into his brain frantically.
Huh? Why is it not as painful as I imagined? Kang Chi frowned in confusion. The last time he analyzed the lens process, it was much more painful than analyzing the lens.
The amount of information analyzed this time should be no less than that of analyzing the lens.
Kang Chi had originally prepared for the pain for a few minutes,
But he didn’t expect that the pain disappeared after only three seconds! At the same time, he was surprised to find that the knowledge analyzed this time was also deeply integrated with the knowledge and theory he had learned by himself during this period. It felt like learning a lot of theories and then practicing them countless times.
It felt like a natural and integrated feeling.
Kang Chi couldn’t help but feel a little surprised.
I didn’t expect that learning theoretical knowledge in advance would have such an effect? With theory + practice, Kang Chi now felt like a real single crystal silicon smelting expert. He knew all the difficulties and solutions of smelting, and he could fully understand the design and principle of the single crystal furnace.
This is so cool!
Kang Chi spent more than ten minutes slowly recalling the knowledge in his mind, and then continued to analyze with expectation.
Analysis of chamfering process,
Consume 5 mastery points!
Analysis of multi-wire cutting process,
Consume 10 mastery points!
Analysis of chemical mechanical polishing process,
Consume 10 mastery points!
After consuming 30 mastery points, Kang Chi has completely mastered all the production process flows and equipment manufacturing technologies of 12-inch silicon wafers.
Now, he is no longer afraid of anyone asking questions about silicon wafer manufacturing.
Even the best researcher of Shin-Etsu ChemicalOr engineers, they certainly can’t do it like him, combining theory and practice in one, and mastering silicon wafers so thoroughly.
Finally, everything is ready, only the east wind is missing! In order to lay the groundwork for the next plan, Kang Chi turned on the computer and started writing a paper.
At the same time, he also contacted a lawyer who specializes in patents and started applying for several important patents.
Once the patent application is approved, he can start submitting the paper. —— At the same time, in the Blue Lake Resort in Dongyang City, two men were sitting on a lounge chair smoking.
The man sitting on the left wore sunglasses, had a big back hair with a bit of literary style, and only a thin blue suit on his body, which was quite a bit of a fresh meat.
But the wrinkles on the corners of his eyes betrayed his age, which was no less than 40 years old.
While puffing away his cigarette, he kept looking at the lawn in the distance. Only after he put out his cigarette did he turn to the middle-aged fat man beside him and said: “I heard that the city intends to set up a separate high-tech zone in the development zone?”
”Is Mr. Deng so well-informed?” The middle-aged fat man narrowed his eyes slightly, “I just found out about this this morning.”
”Are there any preferential policies?”
”The land price is 40% of the normal market price, half sold and half given away, tax-free for three years, and after three years, it will be charged at the normal 15% for high-tech enterprises, but the prerequisite is that the investment scale is at least 100 million.”
”Well, the policy is very good. Director Wang, do you 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 will definitely not work. But if you set up a subsidiary and make it 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 100 million yuan, and it must be placed in the supervision account. If the project is not launched within half a year, you can’t take a penny of the money in the account.”
After hearing this, Deng Xing frowned immediately.
”Is there no way to make some concessions?”
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 Director Guo.”
When Deng Xing mentioned Director Guo, he felt a toothache.
After a moment of silence, he asked unwillingly: “Is there any other way?”
”There is a way to try, but it may not work.”
”Oh? Tell me about it?”
”It’s very simple. This high-tech zone has just started. The higher-ups have a good idea and think it is a great opportunity, so they dare to set such high requirements.”
”But in fact, after seeing such strict requirements, it is still unknown whether anyone will respond.”
”Once the hot cake is given away, but no one wants to try it, should the requirements be lowered?”
After hearing this, Deng Xing’s eyes lit up and he said with a smile: “Director Wang still has a way. As long as you delay it a little bit… Don’t worry, the old rules will still apply after the matter is done.”
”Hey, look at what Mr. Deng said, what do you mean by delay?” Director Wang said with a serious face, “We are all doing things according to the regulations. It is not up to me to decide whether it works or not…”
”Oh, yes! Director Wang is right. I expressed it incorrectly. Don’t take it to heart…”
Deng Xing quickly poured him a cup of tea to moisten his throat as an apology…
