Technology: breaking the hegemony that monopolizes the world

Laymen watch the excitement, while insiders watch the doorway.

How many wafers can be cut from a single wafer?

This depends on the size of the wafer and the yield rate.

At present, the so-called 6-inch wafer and 12-inch wafer in the industry are actually the abbreviation of wafer diameter, but the value of this inch is an estimated value.

The actual diameter of the wafer is divided into three types: 150mm, 300mm and 450mm, and 12 inches is approximately equal to 305mm. For the convenience of calling, it is called a 12-inch wafer.

How many wafers can be cut out of a crystal cylinder depends on the purity of the raw material silicon, the pulling speed and temperature control. The thicker the diameter of the silicon crystal cylinder, the harder it is to pull out good quality, so the larger the size, The higher the technical difficulty, the 12-inch fab is more advanced than the 8-inch fab, and the degree of difficulty is higher.

The wafer is cut out, and then the number of chips cut out on the wafer is counted.

For example, if an 8-inch wafer with a small diameter uses a 2.0-micron process, it can generally cut out 588 pieces of 64M DRAM (memory); as for a 12-inch wafer, there are more finished products that can be cut out. .

Of course, the most important thing is that because impurities pose a great threat to these perfect silicon lattices, before entering the clean production room, the manufacturing personnel of the world's first-class manufacturing plants must wash their bodies in advance, wear dust-proof clothing, Armed with precautions.

Therefore, the wafer manufacturing environment is thousands of times cleaner than ordinary operating rooms.

Then the wafers will be sent to the clean room in a dust-free state and packed into sealed containers, and sent to the chip foundry for subsequent production steps.

Such attention and tossing, so it is normal for a fab with a monthly production capacity of about 100,000 wafers to invest tens of billions of Xiayuan.

Experts know this, so when they heard the news from the media outside, they all shook their heads and said it was impossible.

Five hundred thousand twelve-inch wafers, that's not half a million twelve-inch sheets of paper!

Once upon a time, in the wafer manufacturing industry.

Hanxing, Neon, TSMC and a group of younger brothers and allies accounted for more than 80% of the output of the 12-inch standard.

The Great Xia Kingdom is working hard, but at the beginning, it was the Great Xia Kingdom who begged them to build factories by relying on cheap human resources and preferential policies.

It hasn't been a few years, and the Great Xia Kingdom has actually turned salted fish over?

For a while, the stocks of Han Xing and other semiconductor companies fell in response, but the main business was large enough, so the decline was not sharp.

Mobile phone manufacturers, graphics card manufacturers, and other industry giants that demand chips have not ended up until now.

First, it is useless to enter the market. After all, they are a downstream industry that manufactures finished products. Now that there is a shortage of chips, it will be bad if they cause trouble.

Second, there are industrial barriers. The upstream industry manufactures high-end raw materials. If they can do it, they can do it.

The third is purely a question of interests.

Users in Europe and the United States are users, and users of Daxia, Nihong, and Korea are also users. After the game, they are bound to be evil to the other users, so do they still make money?

Didn’t you see that after Facebook turned its face, it couldn’t enter the Daxia market, which made the robot president feel weird every day. Seeing other people go in to make money is more uncomfortable than him losing money.

Of course, it is not easy for mobile phone manufacturers and companies in other industries to step down, but money can pass through ghosts and gods.

After checking, some "experts" appeared on various platforms such as bibs, post bars, and forums. They all had big names. They were either graduates of a certain university, or executives of a certain company, or even members of certain associations. boss.

When these people posted articles, they talked about hype, but only one theme. Jiuzhou Technology Company may have the ability to produce 12-inch wafers, but it is definitely a laboratory product, and a wafer is like a gold wafer.

Xia Xin announced the news and exaggerated the description. In fact, the real purpose is to deal with the increasingly corrupt public opinion atmosphere and the company's stock price in China.

Between the lines, it even hinted vaguely that there might be some department's handwriting in it.

After all, the three major industries of this Kyushu technology company are not related at all.

Companies like Han Xing also woke up after being shocked for a while at the beginning.

If this is an empty plan, if my side lowers the price in order to save future market share, wouldn't it follow the other party's wish?

Isn't there a movie line?

Let the bullets fly for a while.

But they forgot that bullets can turn (funny).

Encouraged by sharing the 20 million Xia Yuan bonus, Li You, Zhang Yantai and a dozen others worked overtime and were model workers.

They are obviously carbon-based humans, but they suddenly turned into a 007-like overtime madman.

"You work day and night like this every day, and the accuracy of the mechanical arm is a little out of balance..."

Gu Qing would come to the fab every two days to adjust and repair the robotic arm, and at the same time give psychological counseling to the group of "worker bees".

"The body is the most important thing. Everyone should pay attention to rest. Only by resting well can the mental state of work be good and work tasks can be completed well."

Regarding Boss Gu's admonition of "extremely caring", basically everyone nodded, and then returned to work with dark circles under their eyes.

Boss Gu sighed, only feeling that there are many sins on his body at this moment.

Didn't I just say something, let their relatives participate in the bionic mechanical prosthesis as soon as possible, depending on the completion of everyone's work tasks?

As for such a waste of sleep and food?

I can't help it, the department over there doesn't have a letter of approval every day, so I can only treat each quota strictly, and I really want to pass the review as soon as possible. If this thing goes on the market, it will make more money than any smart sweeping robot...

"I'm such a fried merchant (no typo)..."

Shaking his head, Boss Gu went to the production workshop and storage department of the home appliance manufacturing factory.

Thanks to the gift of Vice President Gao, the popularity of Titan Star series smart home appliance robots has once again been fired.

Smart sweeping robots are sold out again.

Now the total shipments have exceeded one million, thanks to the previous strategy of "conscientious entrepreneur" Boss Gu.

All the basic version of the machine is priced at the real "friend price", the profit itself is very low, and it occupies the market share.

Then cooperate with higher-priced, irreplaceable garbage bags, exclusive cleaners, cleaning parts and other consumables.

Ordinary users have enjoyed a good life that is really "delicious and lazy" for a month. In order to continue not cleaning, not washing dishes, and looking at the high but acceptable material prices, they sighed and placed additional orders.

The meat can be eaten with a slow knife, and the mouth is full of oil.
