Chapter 153 12-inch wafer

The next day, the semiconductor factory. Engineers have connected the central transformer, and each workshop can be connected to such a power supply nearby. Even if Su is most busy with official business, he must take the time to come over, because he has to test the machine.

"Throw sand!"

"Carbon!"

"Power up!"

Before the smelting boiler, Su gave instructions one by one in the most orderly manner. It takes a high-temperature furnace to melt the minerals, and the temperature inside is 2000°C, which is enough to melt a large part of the ore.

The sand is quartz sand, quartz sand is not uncommon, and it is usually put in the fish tank. But it plays a vital role in the semiconductor industry because it can refine silicon, which accounts for more than 90% of the use of the semiconductor industry, such as processors.

Carbon is inconspicuous, but only when it fuses with silica in quartz sand at high temperatures can silicon be formed.

This machine is very advanced, with a display screen, semi-intelligent control, as long as you set the corresponding parameters, put in the relative raw materials, and finally be able to get what you want.

And it runs very fast, tightly for more than half an hour, with a gentle tick. The boiler gradually ceased to operate.

But the machine was still running, and it took more than ten minutes for the product to be delivered through the guò conveyor port. Seeing the conveyor belt turning, everyone watched with anticipation.

"Da!"

With a slight sound, the first jet-black silicon ingot was sent out, but there was still a cylindrical shape behind it, which was very pleasant to look at.

"That's not right! That's too much, right? The workers were a little surprised to see the steady stream of silicon ingots being delivered.

"Two tons of quartz sand of the same purity, I'm afraid it can't be refined so much, right? And it looks extremely pure, not like it was first refined. Another experienced worker was also surprised,

Liu Dacheng also found out that something was wrong, and hurriedly instructed the engineer next to him: "Take a piece and send it for testing." ”

Su is the most supportive, it seems that it is still too bad, I already knew this. He should have tested it himself first, and then let them know when he had set it up, and now he just wanted it not to be too shocking.

"Mr. Su and Liu Gong, the purity of this silicon ingot is 99.99999999%, which meets the purity of electronic-grade silicon." The engineer who went and came back was out of breath and couldn't connect the airway.

As soon as he heard this number, all the knowledgeable people in the field stared out their eyes, but Su was the most inexplicable, but he probably knew that this number jù was a bit of a drawback, and it sounded very powerful in short.

Hold your forehead and quietly let Little Superman investigate. Without waiting for them to speak, they took the first step to explain: "This machine has already integrated the next few refining steps, which can save time. ”

"I see."

"Good Bad ......"

Under normal circumstances, the silicon refined for the first time is only 98% pure, and then it will be refined n times in the future.

It sounds lofty, but the current situation in China is a cruel reality.

China's industry is backward, and it is not difficult to commercially refine to 98% purity, but this is only metallurgical-grade silicon, which does not meet the requirements of microelectronic devices. So what to do? We simply do not have this technology, which is monopolized by Europe, the United States and Japan.

So they sold it to Germany, the United States, and Japan at a price of $1 per kilogram, and after they were purified, they bought it back at a price of $50-80......

The loss in this sounds chilling. But you can't help it, the purity difference of 0.0001 is huge, and it will almost reduce the quality of the finished device.

The Chinese Academy of Sciences has issued an announcement saying that there is a 100-year difference between domestic industry and some areas in Western countries.

Look at this instrument. Liu Dacheng and other engineers were not only unhappy, but only discouraged. They thought that the gap of 100 years was alarmist by the Chinese Academy of Sciences, but now they take a look. There is really a difference of a hundred years.

What's even more odious is that these Western devices are not sold when they have money, and they are used as their strategic resources, as long as these technologies are in their hands, they will never be afraid of being surpassed by you, China.

Su really didn't expect that just the first boiler would calm everyone down, and he secretly blamed himself in his heart, but fortunately it was not a big deal. In addition, the huge body of this machine makes sense.

The second workshop is also a furnace for the purpose of 'growing' the silicon.

Then there is cutting, grinding, polishing...... Dozens or hundreds of steps, extremely cumbersome.

Just to test the machine once, it took several days, one reason is that the production line has not yet been formed, and the other is that everyone is not familiar with these instruments, and Su can only clumsily let the little superman teach, and he has been delayed a lot of time, and he rushed to the factory every day, and he has forgotten to sleep and eat.

I don't know how many silicon crystals have been destroyed, I don't know how many times I've been worried, I don't know how much sweat has come out, in short, Su is about to go crazy, and his brain is swollen.

But when the first 12-inch, 20nm process wafer was transferred from the instrument, everyone couldn't help but cheer in the dust-free workshop.

It worked! This is something that no one could have imagined.

The investment in the final semiconductors is not small, and hundreds of millions of dollars have been invested in it, not including more expensive instruments. But in the wafer fabrication plant, these hundreds of millions of investments are simply inconspicuous, and the people in the factory have no score in their hearts and have been anxious to work.

But now seeing this high-quality, high-end wafer, they can't suppress the excitement in their hearts, and they can't help but cheer. I believe that if the final end announces that it has successfully made a 12-inch wafer, the industry will definitely be shocked.

"How much would this thing be worth if it were sold like this?" Su held the wafer in both hands, feeling precise and beautiful.

It is indeed very beautiful, and it can even be used as a work of art, and it is very stylish to swing it into the living room at home, and some people even use the wafer as jewelry after processing, which is high-end and high-end.

"Such a wafer can be processed into hundreds of chips at a price of more than $1,000." Liu Dacheng is very familiar with this.

"$1,000...... How many sheets can we make per month for this line? Su asked again.

"The machinery is very advanced, and a lot of steps have been saved, so it shouldn't be a problem to produce 100,000 sheets a month when the workers are proficient." Liu Dacheng calculated, this number is still relatively conservative.

"In other words, we can reach $100 million a month?" Sue was most surprised, it was more than he expected.

“…… That's true in theory. Liu Dacheng said euphemistically: "But you need to use orders." ”

If no one places an order, it's useless if you make a million copies a month. Moreover, the company's expenses are very large, just wages, electricity bills, etc., which need to be tens of millions of dollars per month, and you can't find the order to specify a loss. In fact, the global wafer factories have collapsed badly in recent years because of upgrading, and only a few have played well, Intel, Samsung, TSMC, and SMIC...... Not at all
