Galaxy Technology Empire

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, which 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 takes about half an hour to produce one furnace of pure silicon wafers, and it can produce 20 furnaces a day, which means each furnace is about 2.5 tons.

Therefore, the required C31 fullerene is about 4.2 tons, and these 4.2 tons of C31 fullerene can be used for 1,200 hours.

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

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

A 12-inch round wafer generally weighs about 100 grams. Even if Neutron Star Materials Company produces 12-inch round wafers, it can produce about 12.5 million wafers a month.

Of course, due to different processes, the silicon wafers produced by Neutron Star Materials are square, which is different from the round 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 round wafer, it is about 200 square centimeters larger.

Currently, 12-inch round wafers cost 120 to 125 US dollars a piece, and demand exceeds supply. All wafer factories have placed orders until 2020.

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

Huang Junjie plans to set the price of 30 centimeter wafers at 1,000 Chinese yuan per piece.

What is a huge profit? This is a huge profit. The cost of 20 Chinese yuan is sold for 1,000 Chinese yuan, which is a full fifty-fold increase.

…

August 20th.

Neutron Star Materials' pure silicon wafer production line is finally ready for 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 Star Map Design Company).

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

Zhang Rujing, Wang Bosi and others are elites in the semiconductor industry. It is obviously the first time for them to see a silicon wafer production line like this.

As the president of Neutron Star Materials, Huang Yongdong has been working hard on the production line for more than half a month, and now he can finally give it a try to see what the production line is like.

"Everyone is in position, start adding materials." Huang Yongdong gave the order, and the workers in all aspects began to operate.

The 98% pure polysilicon ground into particles is poured into the electric melting furnace.

To prevent the polysilicon in the electric melting furnace from reacting with the air, the furnace is sealed and filled with inert gas.

In about twenty minutes, C31 fullerene was added to the completely melted polysilicon.

In less than five minutes, the first large-area pure silicon wafer was freshly produced. After cutting with a laser, sixteen 30cm pure silicon wafers entered the cooling area.

Huang Yongdong took out four pieces from it very nervously.

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

Zhang Rujing held the pure silicon wafer, and his hands trembled involuntarily.

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

Huang Haojie smiled and said loudly:

"From today on, we will redefine silicon wafers, because we will not call them inch-round wafers, but 30-centimeter-square wafers."

"Ha ha……"

“That’s right, we have the final say in the future of silicon.”

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

"It's still early! Next, we will subvert the entire chip industry and destroy Sanxin and Intel completely." Huang Haojie said loudly.

"That's right! Let Sanxin, Intel, and Taichi Dian finish them all." Wang Bosi, as a Chinese chip man, has had enough of the arrogance and prejudice of these foreigners over the years.

In fact, silicon wafers are the main raw materials for integrated circuits, accounting for 32% of the raw material costs of integrated circuits. They are the single largest upstream raw material used.

At present, the main suppliers of global silicon wafers include Sunland's Shin-Etsu and Segao, Dongtangguodong Island's Global Wafer, Hans' Silitronic and Colliers LG Chem. The total market share of these five suppliers is as high as more than 90%.

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

In the semiconductor manufacturing industry, silicon wafers of various sizes and specifications need to be used, usually including 4-inch, 5-inch, 6-inch, 8-inch and 12-inch products.

Among them, 12-inch products have a large market share, close to 2/3 of the overall market; in addition, 8-inch products also have a large market share, occupying more than 1/4 of the market share; while the sizes are smaller (6 inches and below) ) product market demand is relatively small.

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

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

According to data from the Dongtang Electronic Materials Industry Association, the annual growth rate of domestic demand for 8-inch silicon wafers has stabilized at around 10% in recent years. The domestic demand for the whole year of 2016 was 8.04 million wafers, and the demand in 2018 is expected to be 810,000 wafers/month. about.

Currently, only a few foreign-invested manufacturers in the Tang factory are capable of producing 8-inch silicon wafers. The total production capacity is 233,000 wafers/month, leaving a market gap of about 577,000 wafers/month.

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

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

This is also the reason why he previously strongly advocated the development of 12-inch wafer fabs in Dongtang.

In fact, from a global perspective, the production capacity and market for large-size silicon wafers have been basically monopolized by Sunland, Hans, Colliers and Dongtang Guodongdao District companies.

If Dongdao District and Dongtang Kingdom are of the same mind, it would be easy to say. The problem is that their relationship with Dongtang Kingdom is very tense. In this way, Dongdao's production capacity and technology cannot be counted as Dongtang Kingdom.

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

However, the market share of the five major suppliers, Shin-Etsu, SGC, Global Wafer, Silitronic and LG, is higher, reaching 98%; at the same time, the market share of Global Wafer in Dongdao District has decreased.

It can be seen that the supply of large-size silicon wafers is mainly monopolized by foreign companies. It is crucial to independently control large-size silicon wafers, and domestic substitution is the general trend.

In 2017, Dongtang's integrated circuit import volume reached 377 billion US dollars, a year-on-year increase of 10.1%; the import value was US$260.1 billion, a year-on-year increase of 14.6%, accounting for 14.1% of Dongtang's total import volume. It can be seen that Dongtang's integrated circuits are exported to the outside world. Dependence is very serious.

In addition, the China-Singapore Communications Incident in 2016 raised the topic of independent controllability of the integrated circuit industry to a new level, and silicon wafers, as the upstream of the industry, are expected to benefit.

In fact, as early as 2014, Dongtang established the "Very Large Scale Integrated Circuit Manufacturing Technology and Complete Set of Processes" project, known as the "02 Special Project", which includes a large silicon wafer industrialization project to concentrate on conquering the 12-inch silicon wafer volume. Childbirth difficulties.

At present, there are at least nine 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, possible new production capacities in the future include: Yiswei and Core Dynamic Energy signed a letter of intent to cooperate with Xi'an High-tech Zone, and will invest tens of billions to establish a silicon material industry base to break the monopoly of 12-inch silicon wafers; Baoli GCL released electronic-grade polysilicon products, and wants to enter the integrated circuit silicon material industry.

But now they don't have to do it, because Neutron Star Materials Company is fully engaged in production, which can not only satisfy the Dongtang market, but also export.

Anyway, domestic silicon wafer companies are half-dead. Huang Haojie is already preparing to completely kill the silicon wafer business of Shin-Etsu, Seng Gao, Global Wafer, Silitronic and LG. At least they will not make a dime in the Dongtang market.
