Laymen watch the excitement, while insiders watch the door.
How many wafers can be cut from one wafer?
This depends on the size of the wafer and the yield rate.
The current so-called 6-inch wafers and 12-inch wafers in the industry are actually the abbreviation of wafer diameter, but the inch value is an estimate.
The actual wafer diameter is divided into three types: 150mm, 300mm and 450mm, and 12 inches is approximately equal to 305mm. For the convenience of naming, 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 silicon processed, 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 wafer factory has a more advanced process than the 8-inch wafer factory, and the difficulty factor is higher.
The wafer is cut out, and then the number of wafers cut out on the wafer is counted.
For example, if a wafer with a small diameter of 8 inches uses a 2.0 micron process, it can generally cut out 588 pieces of 64M DRAM (memory memory); as for a 12-inch wafer, more finished products can be cut out. .
Of course, the most important thing is that because impurities pose a great threat to these flawless silicon lattices, manufacturing personnel in world-class manufacturing plants must wash themselves in advance, wear dustproof clothing, and Be armed and take precautions.
Therefore, the wafer manufacturing environment is thousands of times cleaner than an ordinary operating room.
The wafers are then sent to a clean room in a dust-free state, packed into sealed containers, and sent to the chip foundry for subsequent production steps.
With so much care and effort, it is normal for a fab with a monthly production capacity of about 100,000 wafers to invest tens of billions of dollars.
Because insiders knew this, 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 are not half a million twelve-inch sheets of paper!
Once upon a time, in the wafer manufacturing industry.
Korean Star, Neon, TSMC and a host of younger brothers and allies account for more than 80% of the output of the 12-inch standard.
Daxia is working hard, but in the beginning, it was Daxia that begged them to build factories with its cheap human resources and preferential policies.
Not even a few years later, Daxia Kingdom has turned around?
For a time, 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 major manufacturers in chip demand industries have not come to an end until now.
First, there is no point in entering the market. After all, they are a downstream industry, manufacturing finished products. With the current chip shortage, it will be bad if they get into trouble.
"The Point Guard Is Here"
Second, there are industrial barriers. The upstream industry manufactures high-end raw materials. If it works, it works, and if it doesn’t, it doesn’t work. No matter how much they “support” or “cooperate”, there will be no results in a short time.
The third one is simply a matter of interests.
Users in Europe and the United States are users. Users in Daxia, Neon, and Korea are also users. If they end the game, they will inevitably hate the other users. Do they still want to make money?
Don’t you see, after Facebook fell out, it couldn’t enter the Daxia market, which made the robot CEO feel weird every day. Watching other people go in and make money was even more uncomfortable than him losing money.
Of course, it is difficult for mobile phone manufacturers and companies in other industries to step down, but money can speak to ghosts and gods.
After a quick review, some "experts" appeared on various platforms such as scarves, post bars, and forums. They all seemed to have great names. They were either graduates of a certain university, executives of a certain company, or even members of certain associations. Boss.
When these people publish articles, they are talking about nothing but one theme. Jiuzhou Technology Company may have the ability to produce 12-inch wafers, but they are definitely laboratory products. A wafer is like a gold disc.
Xia Xin announced the news and gave an exaggerated description. In fact, the real purpose was to deal with the increasingly corrupt public opinion atmosphere and the company's stock price in the country.
Between the lines, there is even a hint that there may be some handwriting from some departments.
After all, the three major industries of this Jiuzhou technology company are not related at all.
Companies like Korean Star also woke up after being shocked for a while at first.
If this is an empty city strategy, if our side lowers prices in order to regain future market share, wouldn't it mean that we are following the other party's wishes?
Isn’t there a line from a movie?
Let the bullets fly for a while.
But they forget that bullets can turn (funny).
Encouraged by sharing the bonus of 20 million Xia yuan, Li You, Zhang Yantai and more than a dozen people worked overtime and became model workers.
He is obviously a carbon-based human being, but he has become a 007-like overtime maniac.
"You guys are doing this day and night every day, and the accuracy of the robotic arm has been somewhat out of balance..."
Gu Qing comes to the wafer manufacturing plant every two days to debug and repair the robotic arm, and at the same time provides psychological counseling to these "worker bees".
"The body is the most important thing. Everyone should pay attention to rest at ordinary times. Only by taking a good rest can you be in a good mental state at work and complete your work tasks well."
In response to Boss Gu's "caring" advice, basically everyone nodded and returned to work with dark circles under their eyes.
Boss Gu sighed, feeling that there were a lot more sins on his body at this moment.
Didn't I just say that depending on how well everyone completes their work tasks, their relatives can participate in bionic mechanical prostheses as soon as possible?
As for working so sleeplessly and forgetting food and sleep?
I have no choice. The department over there can’t confirm the accuracy in a day, so I can only treat every quota strictly. I also want to pass the review as soon as possible. If this thing is put on the market, it will be more profitable than a smart sweeping robot...
"I'm really a frying merchant (not a typo)..."
Shaking his head in his mind, Boss Gu visited the production workshop and warehousing department of the home appliance manufacturing factory.
Thanks to Vice President Gao, the popularity of the Titanstar series of smart home appliance robots has once again become popular.
Smart sweeping robots are out of stock again.
Total shipments have now exceeded one million, thanks to the strategy of former “conscientious entrepreneur” Boss Gu.
All basic versions of the machines are priced at real “friend prices”, with very low profits and occupying market share.
Then match it with higher-priced, irreplaceable consumables such as garbage bags, exclusive detergents, cleaning work parts, etc.
Ordinary users have enjoyed a good life of "eating well and being lazy" for a month. In order to continue not cleaning or washing dishes, they looked at the high but acceptable price of materials, sighed and placed additional orders.
Cutting the meat with a slow knife can make your mouth full of oil.
