Flowers for the company's headquarters.

“…… Neutron Star Materials Co., Ltd. has initially achieved mass production of 30 centimeter square wafers, with an annual output of 12 million pieces......"

Yu Mingguang watched the broadcast of national news, listened to the reporter's introduction in a low tone, and couldn't help but smile bitterly.

Mr. Ren on his side said with a smile: "Lao Yu was slapped in the face!" ”

"Haha...... This face is worth it. Yu Mingguang can see it.

"But I'm very curious about how they came up with a 30 centimeter square chip." Mr. Ren knows that the silicon wafers produced by all wafer factories are wafers.

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

Because of the generation method of high-purity monocrystalline silicon, it is determined that wafer factories can only produce wafers, after all, high-purity monocrystalline silicon rods are cylindrical.

Originally, the two irregular cones at the head and tail were to be cut off, and if they were cut into square cylinders, nearly two-fifths of the high-purity monocrystalline silicon would be wasted, so would the money be profitable?

So they can only produce wafers, but wafers have a very difficult problem for chip processing, that is, they can't be fully utilized.

After all, chips are quadrangular, and no matter how you cut them, there will always be a part of the wafer that will be wasted.

"I'm afraid the Suns and Hans and Colliers won't be able to sit still." Yu Mingguang said with a smile.

After all, the mass production of silicon wafers of Galaxy Technology is a good thing for Huawei, because Huawei itself has no chip production capacity, and it is all due to Taiwan's base electrical foundry.

In fact, Yu Mingguang is right, the five major silicon wafer suppliers of Shin-Etsu, Shenggao, Global Wafers, Silitronic and LG, as soon as they heard the news, it was as if they had been hit by five thunderstorms.

The name of the pulverizer in the developed countries of the Eastern Tang Dynasty is not called in vain, especially LG Chem, which can be said to hate Galaxy Technology, which has hit LG Chem's battery market hard, and is now engaged in silicon wafers.

Are you Galaxy Technology going to completely wipe out my LG Chem? What do we have against and what do we hate? If resentment can kill, Huang Haojie is estimated to be cut by a thousand knives.

The stock market reacted most sensitively and quickly to this incident, and the day after the national news, the domestic silicon wafer concept listed companies were environmentally friendly.

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

Even two companies in the Sun Country, which produce high-purity monocrystalline silicon raw materials, have suffered from the fish in the pond.

The meteor shower company, which had been prepared for a long time, harvested a large wave of leeks this time.

In addition, Colliers is also treacherous at this time.

On August 25, according to Yonhap News Agency, the Colliers Court made a first-instance judgment on the bribery case of Lee Jae-ming, vice chairman of Sanxin Electronics, on the afternoon of the 25th, and found that Lee Jae-ming bribed former President Ms. Park as the successor of Sanxin, and was sentenced to 5 years in prison on charges of corruption and perjury.

Colliers Central District Court previously reported that on the afternoon of August 25, local time, five executives of Sanxin Group, including Li Zaiming, were sentenced in the first instance.

Colliers prosecutors allege that Lee Jae-myung, vice chairman of Sanxin Group, is suspected of bribing former President Ms. Park and her close confidant Choi Soon with 43.3 billion Korean won (about 249 million Chinese won) or intending to offer bribes.

It's a sad story to celebrate.

The troubled Sanxin Group, a month ago, Lee Kun-hee broke up Chunmen, the eldest daughter divorced her husband, and now the only son Lee Jae-ming has been sentenced again, plus Lee Kun-hee 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 due to the lack of use of Thor batteries, Sanxin mobile phones have been losing in the international market, and now they are indifferent to the mass production of silicon wafers by neutron stars.

……

The chip manufacturing enterprises in Dongtang were moved.

The top two chip foundries in China, Chipcore International and Hua Hong Semiconductor.

The top five domestic memory chips, Yangtze River Storage, Jinhua, Unisplendour, Changxin, and Trillion Innovation.

These companies need to use silicon wafers to produce chips.

If you include Taijidian, UMC, Powerchip, and the world's advanced in Dongdao, Dongtang's semiconductor foundry output accounts for about two-thirds of the world's total output.

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

The president of Huaxin International is Zhang Haijun, who just took office in July this year, and the official mass production of the Galaxy Technology silicon wafer factory is a big thing 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 of Shin-Etsu, Shenggao, Global Wafer, Silitronic and LG.

Since the beginning of this year, the price of wafers has been on the rise, from $70 to $120.

However, as soon as the news of the listing of the silicon wafers of Neutron Star Materials was released, the international silicon wafer trading price will have a significant downward trend.

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

Among the large-scale testing departments of Huaxin International.

"Oh my God! Perfect! It was just perfect! An engineer in his forties exclaimed.

"That's right, it's just ingenious, it's hard to imagine how they were made."

"It's not just the square, it's the uniformity of the mass, whether it's the center area, or the edge area, the quality is unexpectedly consistent."

"The purity of monocrystalline silicon wafers is the most terrible, even if it is Shin-Etsu's N13-grade silicon wafers, our instruments can test them, but neutron star silicon wafers are 100% pure, which shows that their purity has exceeded the detection limit of the instrument."

The other engineers also said babblingly.

Zhang Haijun listened to the exclamations and discussions of the engineers, and hurriedly asked:

"You say this silicon wafer is really that good?"

"That's right, it's just a perfect existence." The engineer in his forties was amazed, and after speaking, he picked up one of the square wafers:

"Mr. Zhang, you see, the quality of the center area and the edge area of this silicon wafer is consistent, what does this mean?"

"It means the yield rate!" Zhang Haijun certainly knows what that means.

Because traditional wafers not only cause waste in dicing, it also has another disadvantage, that is, the quality of the center area is not the same as that of the edge area, and the quality of the center area is generally 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 fail.

Some defects are located in the insensitive area of the chip and do not cause the chip to fail.

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

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

Therefore, in the production of general chip companies, the chip cut from the center area of the silicon wafer is of the best quality, and the more it goes to the outside, the worse the quality, or even the waste product that cannot be used.

"Not only is the quality very uniform, but the other properties of the neutron star silicon wafer are also better than ordinary wafers, and I estimate that if the neutron star silicon wafer is used, the yield rate can be increased by 2~5%, which is the detection data." After speaking, the engineer handed a test report to Zhang Haijun.

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

"It seems that we are going to purchase silicon wafers from Neutron Star, and Vice President Li, you will arrange the production line to adjust as soon as possible, so that our production line can adapt to square wafers."

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

"Mr. Zhang, what is the pricing for neutron stars?" The other vice president asked suddenly.

"The Eastern Tang Dynasty is 1,000 yuan in China, which is cheaper than a 102-inch wafer." Zhang Haijun already knew the domestic pricing of neutron star silicon wafers from Zhang Rujing.

"1,000 Chinese dollars a piece in China? They Galaxy Technology will not engage in another foreign price of 1,000 US dollars a piece. The vice president complained.

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

Ahem! The vice president was choked suddenly.

"Is there technology to really do whatever you want?"

"It's not too much, after all, the area of a 30 centimeter square wafer is about 200 square centimeters more than that of a 12-inch wafer, and the quality is very uniform, which is very obvious for the improvement of yield." Zhang Haijun explained with a smile.

Several vice presidents listened to it and suddenly had mixed feelings, this is the arrogance of the technology leader.
