Chapter 90 Building a production line

Soon, Huang Haojie led a large group of engineers and researchers to build the first C31 fullerene production line and the first pure silicon wafer production line in the factory of Neutron Star Materials Company.

Because the service life of C31 fullerene is about 1200 hours, that is, about 50 days.

The production of 1 ton of pure silicon requires 1.66 tons of C31 fullerene.

The first pure silicon wafer production line can produce 50 tons of pure silicon wafers per day, of course, the production line is about half a small furnace to produce one furnace of pure silicon wafers, and 20 furnaces a day, that is to say, each furnace is about 2.5 tons.

Therefore, the C31 fullerene used is about 4.2 tons, and the 4.2 tons of C31 fullerene can be used for 1200 hours.

Therefore, the daily output of C31 fullerene production line is about 1 ton.

These are enough for the time being, after all, 50 tons of pure silicon wafers can be produced a day, and 15,000 tons of pure silicon wafers can be produced in a year, excluding maintenance and the like.

The weight of a 12-inch wafer is about 100 grams, even if Neutron Star Materials produces 12-inch wafers, it can produce about 12.5 million wafers a month.

Of course, due to the different processes, the silicon wafers produced by Neutron Star Materials are square, which is different from the wafers produced by ordinary wafer factories.

The silicon wafer designed by Huang Haojie is a square with a side length of 30 centimeters and an area of 900 square centimeters.

Compared with a 12-inch wafer, it is about 200 square centimeters larger.

At present, 12-inch wafers, a piece of 120~125 US dollars, are still in short supply, and the orders of all wafer factories are scheduled for 2020.

The production cost of one piece of the square wafer of Neutron Star Materials Company (excluding scientific research funds) is about 20 Chinese yuan.

Huang Haojie plans to set the price of a 30-centimeter wafer at 1,000 yuan a piece.

What is Windfall Profit? This is a huge profit, 20 Chinese dollars cost 1,000 Chinese dollars, a full fifty times more.

……

August 20th.

The pure silicon wafer production line of Neutron Star Materials Company can finally be put into trial production.

Wang Bosi (President of Galaxy Group), Huang Yongdong (President of Neutron Star Materials Company), Zhang Rujing (President of Galaxy Semiconductor Company), Du Wei (President of Xingtu Design Company).

plus Huang Haojie, Li Jianhua, Li Xiang and others.

Zhang Rujing, Wang Bosi and others are all elites in the semiconductor industry, and it is obviously the first time they have seen this kind of silicon wafer production line.

And Huang Yongdong, as the president of Neutron Star Materials, has been working on the production line for more than half a month, and now he can finally give it a try.

"Everyone's in place, start feeding." Huang Yongdong gave an order, and the workers in all links operated.

The 98% pure polysilicon, which is ground into particulate matter, is poured into an electric melting furnace.

In order to avoid the reaction of polysilicon and air in the electric melting furnace, the furnace is hermetically sealed and filled with inert gas.

In about 20 minutes, the polysilicon is completely melted and C31 fullerene is added.

In less than five minutes, the first large-area pure silicon wafers are freshly baked, and after laser cutting, 16 30 centimeter pure silicon wafers are sent to the cooling zone.

Huang Yongdong was very nervous and took out four pieces from it.

Everyone surrounded the testing equipment, and after a while, the purity, conductivity and other parameters of the four pure silicon wafers came out.

Zhang Rujing held the pure silicon wafer, and his hands couldn't help but tremble.

"Perfect, it's just ingenious, haha......"

Huang Haojie smiled and said loudly:

"From today, we will redefine silicon wafers, because we don't call it a multi-inch wafer, but a 30 centimeter square wafer."

"Haha......"

"That's right, the future of silicon wafers is up to us."

"With this square crystal factory alone, we Galaxy Group can be self-sufficient." Wang Bosi was excited.

"It's still early! Next, we want to subvert the entire chip industry and let Sanxin and Intel be completely finished. Huang Haojie said loudly.

"That's right! Let Sanxin, Intel, and Taiji Power all be finished. "Wang Bosi, as a Chinese chip person, has had enough of the arrogance and prejudice of these gringos over the years.

In fact, silicon wafers are the main raw materials for integrated circuits, accounting for 32% of the cost of integrated circuit raw materials, and are the upstream raw materials with a large single usage.

At present, the world's silicon wafer suppliers mainly include Shin-Etsu and Shenggao in the Sun Country, Global Wafers in the Dongdao District of Dongtang Province, Silitronic in Hans and Colliers LG Chem, with a combined market share of more than 90%.

However, the production and manufacturing capacity of semiconductor silicon wafers of mainland manufacturers in Dongtang is weak, and their competitiveness in the world is insufficient.

In the semiconductor manufacturing industry, a variety of silicon wafers of different sizes and specifications are used, usually including 4-inch, 5-inch, 6-inch, 8-inch and 12-inch products.

Among them, the market share of 12-inch products is large, close to 2/3 of the overall market, in addition, the market share of 8-inch products is also large, accounting for more than 1/4 of the market share; The market demand for products with small sizes (6 inches and below) is relatively small.

There is a large supply gap for large-size silicon wafers in China, and the monopoly pattern of foreign investors is obvious.

From the perspective of the domestic market, at present, the mainland silicon wafer suppliers in Dongtang mainly produce 6-inch and below silicon wafers, and 4-6 inch silicon wafers can basically meet the demand, but there is a huge market gap for large-size silicon wafers.

According to the data of Dongtangguo Electronic Materials Industry Association, the annual growth rate of domestic demand for 8-inch silicon wafers has been stable at about 10% in recent years, and the domestic demand for 8.04 million pieces in 2016 is expected to be about 810,000 pieces per month in 2018.

At present, only a few foreign-funded manufacturers in Tang plant are able to produce 8-inch silicon wafers, with a total production capacity of 233,000 pieces/month, and a market gap of about 577,000 pieces/month.

In addition, although the current demand for 12-inch silicon wafers in Dongtang is as high as 500,000 pieces per month, Dongtang does not have the mass production capacity of 12-inch silicon wafers and needs to rely on imports.

Zhang Rujing once predicted that the monthly demand for 12-inch silicon wafers is expected to exceed 1.25 million pieces after 2020, and the market supply gap may further expand in the future.

This is also the reason why he previously vigorously advocated the development of 12-inch wafer factories in Dongtangguo.

In fact, from a global perspective, the production capacity and market of large-size silicon wafers have basically been monopolized by enterprises in the Dongdao area of Sun Country, Hans, Colliers and Dongtang Kingdom.

If the East Island District and the East Tang Kingdom are of the same mind, it is good to say, but the problem is that the relationship between them and the East Tang Kingdom is very tense, so the production capacity and technology of the East Island cannot be counted in the East Tang Kingdom.

Taking the 12-inch silicon wafer market as an example, the overall market competition pattern of semiconductor silicon wafers is basically the same.

However, the five major suppliers of Shin-Etsu, Shenggao, Global Wafers, Silitronic and LG have a higher market share, reaching 98%; At the same time, the global wafer market share in the East Island region has decreased.

It can be seen that the supply of large-size silicon wafers is mainly monopolized by foreign companies. It is very important for large-size silicon wafers to be independent and controllable, and domestic substitution is the general trend.

In 2017, the import volume of Dongtang integrated circuits reached 377 billion, a year-on-year increase of 10.1%; The import value was 260.1 billion US dollars, a year-on-year increase of 14.6%, accounting for 14.1% of Dongtang's total imports.

In addition, the 2016 Sino-Singapore communication incident has raised the topic of independent and controllable integrated circuit industry to a new height, and silicon wafers are expected to benefit as the upstream of the industry.

In fact, as early as 2014, Dongtang set up the "Very Large Scale Integrated Circuit Manufacturing Technology and Complete Process" project, that is, the "02 Special", which consists of a large silicon wafer industrialization project to focus on overcoming the difficulties of mass production of 12-inch silicon wafers.

At present, there are at least 9 large silicon wafer projects in China, with a total investment scale of more than 55 billion yuan, and the monthly production capacity of 12-inch silicon wafers under planning has exceeded 1.4 million pieces.

In addition, the possible new production capacity in the future includes: ESWIN, Xindong Energy and Xi'an High-tech Zone signed a letter of intent to invest 10 billion yuan to establish a silicon material industrial base and break the monopoly of 12-inch silicon wafers; GCL-Poly released electronic-grade polysilicon products and intends to enter the integrated circuit silicon material industry.

But now they don't have to do it, because Neutron Star Materials Company is fully producing, not only to meet the Dongtang market, but also to export.

Anyway, domestic silicon wafer companies are half-dead, and Huang Haojie is ready to completely kill the silicon wafer business of Shin-Etsu, Shenggao, Global Wafer, Silitronic and LG, at least they can't make a dime in the Dongtang market.
