"Neutron Star Materials Company has initially achieved mass production of 30 centimeter wafers and can produce 12 million wafers annually."
Yu Mingguang watched the national news broadcast and listened to the reporter's mellow introduction, and couldn't help but smile bitterly.
Next to him, Mr. Ren said with a smile: "Lao Yu must have been slapped in the face!"
"Haha, the slap in the face was worth it." Yu Mingguang looked at it openly.
"But I'm very curious about how they achieved 30 centimeter cubic wafers." Mr. Ren knew that all silicon wafers produced by current silicon wafer factories are round wafers.
It's not that these silicon wafer factories don't want to produce square wafers, it's just that they can't.
Because of the way high-purity monocrystalline silicon is generated, silicon wafer factories can only produce round wafers. After all, high-purity monocrystalline silicon rods are cylindrical.
The two irregular conical pieces at the head and tail have to be cut off. If they are cut into square cylinders, nearly two-fifths of the high-purity monocrystalline silicon will be wasted. Will the money still be earned?
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 of the round wafer will be wasted.
"I'm afraid Sunshine and Hans Gaoli won't be able to sit still." Yu Mingguang said with a smile.
After all, Galaxy Technology's mass production of silicon wafers is a good thing for Huawei, because Huawei itself does not have chip production capabilities, and it is all done by Taiji Electric.
In fact, what Yu Mingguang said was right. Shin-Etsu, Global Wafer, Silitronic and LG, the five major silicon wafer suppliers, were immediately struck by thunder when they heard the news.
The name of Dongtang People's crusher in developed countries is not for nothing, especially LG Chem, which can be said to hate Galaxy Technology. It severely damaged LG Chem's battery market, and now it is engaged in silicon wafers.
Do you, Galaxy Technology, want to completely kill me, LG Chemical? What hatred do we have? If resentment can kill, Huang Junjie will probably be cut into pieces by a thousand cuts.
The stock market reacted most sensitively and quickly to this incident. The day after the national news, domestic silicon wafer concept listed companies were in an environmentally friendly tone.
As for foreign stock markets, they are not far behind either. Listed companies with silicon wafer concepts are in a bloody scarlet state.
Even two Sunland companies that produce high-purity monocrystalline silicon raw materials have suffered.
Meteor Shower Company, which had been well prepared, harvested a large wave of leeks this time.
In addition, Gaoli’s domestic situation is also in turmoil at this time.
On August 25, according to Yonhap News Agency, the High Court issued a first-instance verdict on the bribery case of Sanxin Electronics Vice Chairman Li Zaiming on the afternoon of the 25th, concluding that Li Zaiming bribed former President Ms. Park as the successor of Sanxin, and also committed corruption and perjury.
Sentenced to 5 years in prison.
According to previous news from the Gaoli Central District Court, five senior executives of Sanxin Group, including Li Zaiming, will be sentenced in the first instance on the afternoon of August 25, local time.
Prosecutors accused Lee Jae-myung, vice chairman of Sanxin Group, of bribing former President Park and his cronies Choi Soon-sik 43.3 billion Korean won or intending to pay bribes.
This is really a gratifying and sad story.
The Sanxin Group has been plagued by many disasters. Li Jianxi bought a prostitute a month ago, the eldest daughter divorced her husband, and now the only son Li Zaiming has been sentenced again, and 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 it does not use Thor batteries, Sanxin mobile phones are losing ground in the international market. Now they are indifferent to the mass production of silicon wafers by neutron stars. It is obvious that Sanxin Group has too much to take care of itself.
The chip manufacturing companies in Dongtang took advantage of this trend.
The two largest domestic chip foundries are Core International and Hua Hong Semiconductor.
Among the top five domestic storage chips, Yangtze Storage, Jinhua Unigroup, Changxin Gigabit Innovation.
These companies all need to use silicon wafers to produce chips.
If you include Dongdao's world-leading Taiwan-based Taiwan Electric Power Corporation, Dongtang's semiconductor foundry output 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 excluded temporarily.
The president of Huaxin International is Zhang Haijun, who just took office in July this year. The official mass production of the Galaxy Technology silicon wafer factory is a big event for the chip industry.
Especially for Huaxin International, because the current silicon wafer output on the market is very stable, it is monopolized by the five major silicon wafer suppliers, Shin-Etsu Global Wafer Silitronic and LG.
The price of the silicon wafer market has been on the rise since this year, soaring from US$70 to US$120.
However, as soon as the news of the listing of silicon wafers from Neutron Star Materials Company was released, the international silicon wafer transaction price will see a clear downward trend.
Zhang Haijun took this matter very seriously. Relying on his old relationship with Zhang Rujing, he quickly obtained ten 30 cm3 wafer samples.
Among the large-scale testing departments of Huaxin International.
"Oh my God! It's perfect! It's simply perfect!" an engineer in his forties exclaimed.
"That's right, this is simply ingenious. It's really hard to imagine how they made it."
"It's not just the square shape, but also the quality uniformity. Whether it's the center area or the edge area, the quality is actually the same."
"The single crystal silicon purity of silicon wafers is the scariest thing. Even Shin-Etsu's n13 grade silicon wafers can be tested with our instruments, but the neutron star silicon wafers are actually 100% pure. This shows that their purity has surpassed the instrument
The detection limit is reached.”
Other engineers also talked about it.
Zhang Haijun listened to the engineers' exclamations and discussions and quickly asked:
"Do you think this silicon chip is really that good?"
"That's right, it's simply perfect." The engineer in his forties marveled in admiration. After speaking, he picked up one of the square wafers:
"Mr. Zhang, look, the quality of the center area and edge area of this silicon wafer is the same. What does this mean?"
"It means yield!" Zhang Haijun certainly knew what this meant.
Because traditional round wafers not only cause waste in cutting, they also have another disadvantage, that is, the quality of the center area and the edge area is different. Generally speaking, the quality of the center area is better than that of the edge.
Defects on the surface of the silicon wafer cause the entire chip to fail by causing part of the chip to malfunction.
Some defects are located in insensitive areas of the chip and will not cause chip failure.
However, due to the decreasing process size and increasing component density, the level of circuit integration is gradually increasing.
This trend increases the likelihood that any given defect will land in the active area of the circuit.
Therefore, in the production of general chip companies, the chips cut from the central area of the silicon wafer are of the best quality, and as they go to the outside, the quality becomes worse, and they may even be unusable waste products.
"Not only is the quality very uniform, but the other properties of neutron star silicon wafers are also better than ordinary round 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." The engineer finished speaking.
A test report was handed to Zhang Haijun.
After Zhang Haijun read it, he handed it to several vice presidents.
"It seems that we need to purchase silicon wafers from Neutron Star. In addition, Vice President Li, please arrange for the production line to be adjusted 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's the price for neutron stars?" Another vice president suddenly asked.
"The domestic price of a wafer in the Eastern Tang Dynasty is 1,000 Chinese yuan, which is cheaper than a 102-inch round wafer." Zhang Haijun already knew the domestic pricing of neutron star silicon wafers from Zhang Rujing.
"Domestic prices of 1,000 US dollars per piece? Galaxy Technology won't come up with another overseas price of 1,000 US dollars per piece," the vice president complained.
"It's not that exaggerated. Overseas, it costs US$250 a piece."
Ahem! The vice president was choked immediately.
“With technology, can we really do whatever we want?”
"It's not too much to calculate. After all, a 30-centimeter-square wafer has about 200 square centimeters more area than a 12-inch round wafer. In addition, the quality is very uniform, which significantly improves the yield rate." Zhang Haijun explained with a smile.
Several vice presidents suddenly had mixed feelings after hearing this. This is the arrogance of a technology leader.
