Chapter 89 Building the Production Line

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

Since 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 an hour to produce a batch of pure silicon wafers. It produces 20 batches a day, which means that each batch is about 2.5 tons.

所以需要所用的C31富勒烯是4.2吨左右，这4.2吨C31富勒烯是可以使用1200小时的。

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, and 1.5 tons of pure silicon wafers can be produced in a year without maintenance and the like.

A 12-inch wafer generally weighs about 100 grams. Even if Neutron Star Materials produces 12-inch wafers, it can produce about 1250 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 round wafers produced by ordinary fabs.

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, the supply of 12-inch wafers costs US$120-125 per piece, and the supply is still in short supply. All fab orders are scheduled until 2020.

As for the square chip of Neutron Star Material Company, the production cost of one piece (not including research funding) is about 20 Chinese yuan.

Huang Haojie plans to set the price of 30 centimeter chips at 1000 Chinese yuan per piece.

What is a huge profit? This is a huge profit. The cost of 20 Chinese yuan is sold for 1000 Chinese yuan, which is a full fifty-fold increase.

……

8 month 20 day.

The pure silicon wafer production line of Neutron Star Materials Company 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. Obviously, this is the first time they have seen a silicon wafer production line like this.

As the president of Neutron Star Materials, Huang Yongdong has been working on the production line for more than half a month, and now he can finally have a try, the situation of this production line.

"Everyone is on position, start feeding." Huang Yongdong gave an order, and the workers in all links began to operate.

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

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

In about 10 minutes, C31 fullerene was added to the completely melted polysilicon.

In less than 5 minutes, the first large-area pure silicon wafer was freshly out of the oven. After cutting and cutting with a laser, the 16 yuan 30 centimeter pure silicon wafer entered the cooling area.

Huang Yongdong took out four pieces from it nervously.

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

Holding the pure silicon wafer, Zhang Rujing's hands trembled uncontrollably.

"Perfect, it's a wonderful workmanship, haha..."

Huang Haojie said loudly with a smile:
"From today, we will redefine the silicon wafer, because we don't call it a round wafer of inches, but a wafer of 30 centimeters."

"Ha ha……"

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

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

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

"That's right! Let Sanxin, Intel, and Taiji Electronics all die." As a Chinese chip man, Wang Bosi has had enough of the arrogance and prejudice of these foreigners these years.

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

At present, the global suppliers of silicon wafers mainly include Shin-Etsu and Sheng Gao of Sun Country, Global Wafer of Dongdao District of Dongtang Country, Silitronic of Hans, and Colliers LG Chem. These five suppliers have a combined market share of more than 90%.

However, the production capacity of semiconductor silicon wafers of mainland manufacturers in the Eastern Tang Dynasty is weak, and their global competitiveness is insufficient.

而在半导体制造业中需要使用各种不同尺寸与规格的硅片，通常包括4英寸、5英寸、6英寸、8英寸及12英寸几大类产品。

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 relatively large, accounting for more than 1/4 of the market share; while the smaller size (6 inches and below ) product market demand is relatively small.

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

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

据东唐国电子材料行业协会数据显示，近年国内对8英寸硅片的需求年增长率稳定在10%左右，2016年全年国内需求为804万片，预计2018年的需求在81万片/月左右。

At present, only a few manufacturers with foreign investment in the Tang factory can produce 8-inch silicon wafers, with a total production capacity of 23.3 pieces/month, and there is a market gap of about 57.7 pieces/month.

In addition, although the current demand for 12-inch silicon wafers in Dongtang is as high as 50 pieces per month, Dongtang does not have the mass production capacity of 12-inch silicon wafers and needs to rely entirely on imports.

Zhang Rujing once predicted that the monthly demand for 2020-inch silicon wafers is expected to exceed 12 million pieces after 125, and the market supply gap may further expand in the future.

This is also the reason why he vigorously advocated the development of a 12-inch fab in Dongtang before.

In fact, from a global perspective, the production capacity and market of large-size silicon wafers have been basically monopolized by companies from Sun Country, Hans, Colliers and Dong Tang Country in Dongdao District.

If the East Island District and the East Tang Kingdom are of the same mind, it is okay to say that the problem is that their relationship with 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, it is basically consistent with the overall market competition pattern of semiconductor silicon wafers.

However, the market share of the five major suppliers, Shin-Etsu, Sheng Gao, Global Wafer, Silitronic and LG, is even 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.Independent controllability of large-size silicon wafers is very important, and domestic substitution is the general trend.

In 2017, Dongtang’s integrated circuit imports reached 3770 billion pieces, a year-on-year increase of 10.1%; the import value was 2601 billion U.S. dollars, a year-on-year increase of 14.6%, accounting for 14.1% of Dongtang’s total imports. It can be seen that Dongtang’s integrated circuits are foreign Dependence is very serious.

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

In fact, as early as 2014, Dongtang established the project of "very large-scale integrated circuit manufacturing technology and complete process", namely "02 special project", which set up a large-scale silicon wafer industrialization project and concentrated its efforts to conquer the volume of 12-inch silicon wafers. Difficulties in childbirth.

At present, there are at least 9 large-scale silicon wafer projects in China, with a total investment scale of more than 550 billion yuan, and the monthly production capacity of 12-inch silicon wafers under planning has exceeded 140 million pieces.

In addition, there may be new production capacity in the future: Yisiwei, Core Kinetic Energy and Xi’an High-tech Zone signed a letter of intent for cooperation, and will invest tens of billions to establish a silicon material industry base to break the monopoly of 12-inch silicon wafers; GCL-Poly released electronic grade polysilicon Products, want to enter the integrated circuit silicon material industry, etc.

But now they don't have to do it, because Neutron Star Material Co., Ltd. is fully producing, which can not only satisfy the Dongtang market, but also export.

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