Chapter 91 Silicon Wafer Listing
Flowers for the company headquarters.

"...Neutron Star Materials Co., Ltd. has initially achieved mass production of 30 centimeter wafers, with an annual output of 1200 million pieces..."

Yu Mingguang watched the national news broadcast and listened to the reporter's cadenced introduction, and couldn't help but wryly smiled.

Boss Ren beside him said with a smile, "Old Yu has been slapped in the face!"

"Haha... this face is worth the slap." Yu Mingguang could see it.

"However, I'm very curious about how they realized the 30 centimeter square wafer." Boss Ren knows that all silicon wafers produced by silicon wafer factories are round wafers.

It's not that these wafer factories don't want to make square wafers, it's that they can't.

Because of the way high-purity monocrystalline silicon is produced, silicon wafer factories can only produce round wafers. After all, high-purity monocrystalline silicon rods are cylindrical.

It is necessary to cut off the two irregular cone heads at the head and the tail. If it is cut into a square column, nearly two-fifths of the high-purity monocrystalline silicon will be wasted. Is this money still profitable?
So they can only produce round wafers, but round wafers have a very difficult problem for chip processing, that is, they cannot be fully utilized.

After all, the chip is quadrilateral, no matter how you cut it, some wafers will be wasted.

"I'm afraid the Sun people, Hans, and Gao Li won't be able to sit still." Yu Mingguang said with a smile.

After all, the mass production of silicon wafers of Yinhe Technology is a good thing for Huawei, because Huawei itself has no chip production capacity, and it is all due to Taiwan-based foundry.

In fact, Yu Mingguang was right. The five major silicon wafer suppliers, Shin-Etsu, Sakako, Universal Wafer, Silitronic and LG, were struck by thunder when they heard the news.

The name of the pulverizer in the developed country of Dongtang is not for nothing, especially LG Chem, which can be said to hate Yinhe Technology, which severely damaged the battery market of LG Chem, and now it is making silicon wafers.

Are you Yinhe Technology trying to drive me out of LG Chem? What kind of enmity do we have? If resentment can kill, Huang Haojie will probably be hacked into pieces.

The stock market reacted most sensitively and quickly to this matter. The day after the national news, listed companies with the concept of silicon wafers in China were full of environmental protection.

As for the foreign stock market, it is not too far behind, and the listed companies with the concept of silicon wafers are bloody scarlet.

Even the two Sun Country companies that produce high-purity monocrystalline silicon raw materials have suffered disaster.

The Meteor Shower Company, which had been prepared for a long time, harvested a large wave of leeks this time.

In addition, Gaoli's domestic situation is also turbulent at this time.

On August 8, according to Yonhap News Agency, the Gaoli Court made a first-instance judgment on the bribery case of Li Zaiming, the vice president of Sanxin Electronics, on the afternoon of the 25th, and found that Li Zaiming was the successor of Sanxin Electronics. , Sentenced to 25 years.

Colliers Central District Court previously reported that on the afternoon of August 8 local time, five senior executives of Sanxin Group, including Li Zaiming, were sentenced in the first instance.

Gaoli prosecutors accused Li Zaiming, the vice chairman of Sanxin Group, of bribing 433 billion Korean dollars (equivalent to about 2.49 million Chinese yuan) or attempting to bribe former President Ms. Park and her cronies Cui Shun.

It's really a happy and sad story.

In the Sanxin Group, which has been plagued by many disasters, Li Jianxi bought the family a month ago. The eldest daughter and her husband divorced. Now the only son Li Zaiming has been sentenced again. In addition, Li Jianxi himself is in poor health.

The current Sanxin Group is like a giant ship that has lost its captain, and its response is very slow.

Especially because of not using Thor batteries, Sanxin mobile phones have been losing ground in the international market, and now they are indifferent to the mass production of silicon wafers by Neutron Star. Obviously, Sanxin Group is now overwhelmed.

……

However, Dongtang's chip manufacturing companies have heard the news.

The top two chip foundries in China are Huaxin International and Hua Hong Semiconductor.

The top five domestic storage chips, Yangtze River Storage, Jinhua, Tsinghua Unigroup, Changxin, Zhaoyi Innovation.

These companies all need to use silicon wafers to produce chips.

If you count Dongdao's Taiwan-based power, UMC, Powerchip, and the world's advanced, Dongtang's semiconductor foundry production accounts for about two-thirds of the world's total output.

However, there are too many uncontrollable factors in Dongdao, so Dongdao enterprises can only be temporarily excluded.

The president of Huaxin International is Zhang Haijun who just took office in July this year. The official mass production of Yinhe Technology's silicon wafer factory is a big event for the chip industry.

Especially for Huaxin International, because the current production of silicon wafers on the market is very stable, it is monopolized by the five major silicon wafer suppliers, Shin-Etsu, Sheng Gao, Global Wafer, Silitronic and LG.

Since the beginning of this year, the price of the silicon wafer market has shown an upward trend, and has soared from $70 to $120.

However, as soon as neutron star material company's silicon wafers are listed, the international silicon wafer transaction price will obviously decline.

Zhang Haijun attached great importance to this matter. Relying on his old relationship with Zhang Rujing, he quickly obtained ten samples of 30 centimeter square wafers.

Among Huaxin International's large testing departments.

"My God! Perfect! It's perfect!" exclaimed an engineer in his 40s.

"That's right, it's so ingenious, it's really hard to imagine how they made it."

"Not only the square shape, but also the uniformity of quality. Whether it is the central area or the edge area, the quality is actually the same."

"The purity of single crystal silicon wafers is the most terrifying. Even Shin-Etsu's N13 grade silicon wafers can be tested by our instruments, but the neutron star silicon wafers are 100% pure, which shows that their purity has surpassed The detection limit of the instrument has been reached."

The other engineers also talked in a hurry.

Hearing the exclamation and discussion of the engineers, Zhang Haijun quickly asked:
"You say this silicon wafer is really that good?"

"It's not wrong, it's a perfect existence." The engineer in his 40s was amazed, and then picked up one of the square chips:

"Mr. Zhang, look, the quality of the central area and the edge area of ​​the silicon wafer is the same. What does this mean?"

"It means good product rate!" Of course Zhang Haijun knew what it meant.

Because the traditional wafer not only causes waste in cutting, but also has another disadvantage, that is, the quality of the center area and the edge area is not the same, generally speaking, the quality of the center area is better than that of the edge.

Defects on the surface of the silicon wafer can cause the entire chip to fail by causing part of the chip to fail.

Some defects are located in insensitive areas of the chip and will not cause the chip to fail.

However, due to the decreasing process size and increasing component density, the circuit integration level tends to increase gradually.

This tendency increases the likelihood that any given defect will land in an active area of ​​the circuit.

Therefore, during the production of general chip companies, the chips cut from the central area of ​​the silicon wafer are of the best quality, while the further to the outside, the worse the quality, or even unusable waste products.

"Not only is the quality very uniform, but other properties of neutron star silicon wafers are also better than ordinary wafers. I estimate that if neutron star silicon wafers are used, the yield rate can be increased by 2 to 5%. This is the test data." A test report was handed over to Zhang Haijun.

After Zhang Haijun read it, he handed it to several vice presidents.

"It seems that we have to purchase silicon wafers from Neutron Star. In addition, Vice President Li, you should arrange the adjustment of the production line as soon as possible so that our production line can adapt to square wafers."

"No problem, I will arrange to solve it as soon as possible." Vice President Li nodded.

"Mr. Zhang, what is the price for neutron star?" another vice president suddenly asked.

"In Dongtang country, a chip costs 1000 Huayuan, which is cheaper than a 102-inch wafer." Zhang Haijun already knew the domestic pricing of neutron star silicon wafers from Zhang Rujing.

"Domestic 1000 Chinese yuan a piece? They Galaxy Technology won't make another foreign price of 1000 dollars a piece." The vice president complained.

"It's not that exaggerated. It's 250 dollars a piece abroad."

cough cough!The vice president was choked up immediately.

"With technology, can you really do whatever you want?"

"It's not too much to calculate. After all, the area of ​​30 centimeter square wafers is about 12 square centimeters larger than that of 200-inch round wafers. In addition, the quality is very uniform, which greatly improves the yield rate." Zhang Haijun explained with a smile.

Several vice presidents heard mixed feelings, which is the arrogance of technology leaders.
