Hand rubbing nuclear fusion live in the wilderness

Chapter 285 An Unexpected Domestic Merchant

The South Korean won will never mind if it can easily cause some trouble for the island country.

The smelting of monocrystalline silicon generally adopts two methods in current human science and technology.

One is the crucible Czochralski method.

The other is the non-crucible suspension zone melting method.

And these two methods are extremely good at the island country, and its technological level is the world's top.

The most important thing is that both methods require single crystal furnaces, which is why island countries can sell single crystal furnaces so expensively.

In this area, not to mention the country of Hua, even its father, the country of Mi, can't match it.

After all, although monocrystalline silicon is important, compared with the key technology of lithography machine, it is still much simpler.

The preparation of single crystal silicon only needs to realize the transformation from polycrystalline to single crystal, that is, the random arrangement of atoms in the liquid phase is directly transformed into an ordered array, and the asymmetric structure is transformed into a symmetrical structure.

The difficulty lies in the crystallization problem of silicon crystals moving at the solid-liquid interface.

Once crystallization occurs, the single crystal silicon on the surface will be quickly oxidized into silicon dioxide.

In addition, the quartz crucible of Czochralski monocrystalline silicon will crack or break after going through high temperature, cooling and other steps, making it unusable again.

Moreover, since single crystal pulling has high requirements on the cleanliness of the crucible, the cleanliness of the used crucible cannot be guaranteed, and at the same time, single crystal silicon has high requirements on the quality of the crucible.

Therefore, it is also difficult to prepare a quartz crucible.

But these things, from today onwards, are all in the past tense.

No matter how cheap your island country’s monocrystalline silicon and monocrystalline furnaces are, no one else will ask for them.

Compared with the single crystal furnace Czochralski method, the 'chemical vapor deposition-silicon core epitaxy method' simply has too many advantages.

The preparation cost is lower, the degree of monocrystalline silicon produced is higher, there is no need for special personnel to stare at the production steps, and so on.

This kind of dimensionality reduction level blow is so fatal.

After basic treatment of all the materials that can be processed, Han Yuan came to the dust-free studio again.

However, unlike the previous preparation of lithography machines, the dust-free environment required for the preparation of monocrystalline silicon is several grades lower.

A class [-] dust-free workshop is sufficient.

The basic materials that had been preliminarily processed in the chemical laboratory were further processed, and Han Yuan checked the instruments and materials to be used again.

After confirming that everything was ready, Han Yuan pulled the camera and said, "'Chemical Vapor Deposition-Silicon Core Epitaxy' has seven steps in total."

"Step [-]: Provide a substrate for pretreatment."

"Step Two: Wash."

"The third step: provide a cavity for the epitaxial growth of single crystal silicon, and a substrate storage device is provided in the cavity, and the substrate is placed on the substrate storage device."

"Step [-]: Introduce reducing gas into the chamber of the preparation instrument, and adjust the pressure and temperature in the chamber to the pressure and temperature required for preparation."

"Step [-]: Introduce a gaseous silicon source into the cavity of the preparation instrument to generate a sacrificial layer with a preset thickness on the surface of the substrate."

"Step [-]: Control the time so that the single crystal silicon layer is formed on top of the sacrificial layer."

"Step [-]: Separate the connector of the single crystal silicon layer and the sacrificial layer from the substrate."

"The seven-step procedure can be monitored and controlled using a computer program, so the 'chemical vapor deposition-silicon core epitaxy method' is very suitable for the mechanized mass production of single crystal silicon."

"Because the produced monocrystalline silicon is in the clean-junction preparation equipment throughout the process, its purity can reach up to 99.9999999%."

"Compared with the traditional single crystal furnace to produce single crystal silicon, using this method is simpler and more convenient, and can save costs."

After Han Yuan's voice fell, the personnel from various countries squatting in his live broadcast room suddenly lit up and became happy.

The personnel from the island nation covered their eyes in pain, not daring to look any more, and the faces of the top executives of the monocrystalline furnace and monocrystalline silicon manufacturers, who were always paying attention to the news, turned pale.

They know they're done, all done.

The glimmer of hope held before has now been completely shattered.

Using this so-called 'chemical vapor deposition-silicon core epitaxy method', the single crystal silicon prepared not only has higher purity, but also has a simpler preparation method and lower cost.

Most importantly, it can be mass-produced through computer control.

This one is enough to crush their current single crystal furnace Czochralski method.

The reason why monocrystalline silicon is expensive all over the world is due to the limitation of production methods on the one hand.

The efficiency of monocrystalline silicon production by monocrystalline furnaces is relatively low, and there are many defective and defective products. Every production will cause damage to high-quality quartz crucibles, and the price will naturally increase.

On the other hand, they are manipulating.

Those companies that can produce top-level monocrystalline silicon will control the production of monocrystalline silicon just like controlling the production of oil, so as to increase their profits.

After all, rare things are more expensive, and when the quantity is small, the unit price will naturally go up. Making money in this way is better and easier than selling in large quantities with low profits.

As long as they control the source technology, someone will come to their door to send money when they live at home.

Just like some manufacturers in Huaguo in the past, even though they were Party A, they still flew here to beg for the same purchase.

After all, although Huaguo has a big market, it is not indispensable. They don't have to sell top-level monocrystalline silicon and earn this little money.

But Huaguo can't do it. Without top-level monocrystalline silicon, many electronic instruments and equipment, even cutting-edge equipment such as aviation and aerospace, cannot be manufactured.

Now, however, all this is shattered.

When the executives of these monocrystalline furnaces and monocrystalline silicon were still worrying about the future, the worse news was reported by the secretary who rushed into the office.

A number of companies in Huaguo, Australia, Windmill, and other countries announced a breach of contract at the same time, and returned the previously signed monocrystalline silicon and monocrystalline furnace purchase contracts.

Other countries seem to be doing better, but very few companies have chosen to suspend cooperation.

Huaguo, on the other hand, was a little too deceitful. All orders for monocrystalline silicon and monocrystalline furnaces were refunded nearly 900 billion yen at one time.

There are even companies that say they don’t want the single crystal furnaces that are already on the way, and they pay the liquidated damages.

In addition, Huaguo's companies also collectively announced the cancellation of all subsequent untraded orders, as well as the cancellation of signed long-term cooperation contracts.

Although a sum of liquidated damages was paid, compared to these orders and subsequent income, it is simply a drop in the bucket, not worth mentioning.
This news, for these monocrystalline furnaces and monocrystalline silicon production companies in the island country, is like adding insult to injury, making these high-level executives angry and insulting, a little dumbfounded, and at the same time extremely desperate.

"Where did this person come from!"

"バカ! ばかやろ! アホ! ボケ! ヘタレ! ドジ!"

Simulating the space, Won is busy processing the materials in his hands.

We have now entered the third step: "Processing Substrate Storage".

This step requires concentration and attention, because if it is not handled properly, it will affect the growth of the single crystal silicon epitaxial layer and affect the quality of the produced single crystal silicon.

But it's almost over.

After processing the last bit of foundation, Han Yuan straightened up, breathed a sigh of relief, relaxed, and looked at the virtual screen.

The dense barrage made him stunned for a moment, a little surprised.

After all, when this kind of boring experiment is going on, it is usually when the popularity is the lowest. Generally, at this time, the number of people in the live broadcast room is at most a million.

But now the number has exceeded 2000 million, and it is still rising.

Han Yuan stopped working and looked at the barrage carefully, wanting to see what happened.

[Fuck, have you watched the trending searches?A number of domestic companies have collectively announced the repurchase of monocrystalline furnaces and monocrystalline silicon from the island country! 】

[I saw it earlier, I am watching the press conference held by the island country company. Their senior management is accusing us of not following the spirit of the contract, but I am laughing like a fool! 】

[Just finished watching it, to be honest, it's really awesome!I will not talk about the importance of monocrystalline silicon, let alone mobile phones and computers, all kinds of electrical appliances such as TVs, remote controls, refrigerators, even airplanes, satellites and so on. flipped. 】

[Awesome, awe-inspiring, anchor, you have to work hard, hope is all on you! 】

[Chong Chong Chong, this is the first time I have seen a domestic businessman so courageous! 】

[If it wasn't for nothing, who would buy the little devil's stuff?Now that there are alternatives, it is natural to choose an alternative. 】

[You are so courageous, what if the anchor can't produce high-purity monocrystalline silicon? 】

[I think it's a bit reckless. Even if I quit, I have to wait for the anchor to get the monocrystalline silicon out before I back out. If I can't get it out, it's all over. 】

[I can't figure it out either. The safest way is to wait until the domestic monocrystalline silicon can be produced by itself and then retreat, but seeing the little ghost jumping in the island country is really fucking relieved! 】

['Black ghosts and ghosts should be damned' sent out super rockets*10, cheers for the anchor! 】

['Anonymous user' sent out a super rocket*1, it's up to you!Anchor, Ollie here! 】

On the virtual screen, all kinds of barrage and rewards are flying.

After watching for a while, Han Yuan roughly figured out what happened.

It turned out that when he was live broadcasting today, many companies in Huaguo joined forces to return the monocrystalline furnaces and monocrystalline silicon purchased from the island country.

The amount exceeds 900 billion yen, which is a full 50 billion when converted into RMB.

Because of this incident, it became a hot search, and the audience went online to discuss this incident in the live broadcast room.

For this, Han Yuan was a little surprised.

These domestic companies and manufacturers are a bit too courageous, right?

Dare to directly fall out and unsubscribe before the result comes out, this courage is beyond Han Yuan's expectation.

If he has already smelted and prepared monocrystalline silicon, this news is nothing.

Businessmen seek profit, and if they have something that can save costs, they will naturally choose it.

But now that the results of his smelting and preparation of monocrystalline silicon have not yet come out, they dare to directly fall out with the island country.

Isn't it afraid that he will overturn the car and can't prepare monocrystalline silicon?

And even if he can successfully prepare monocrystalline silicon according to the usual practice, it will take some time for domestic imitation and large-scale production.

Not to mention that he and the audience in the live broadcast room think so, Daoguo actually thinks so too.

Because it is not in line with business rules.

How can any businessman return a mature supply of materials because of something that has not yet been developed?
The island country even imagined that the anchor could not produce high-quality and high-standard monocrystalline silicon, and these manufacturers would ask them again, and these people must pay the price at that time.

Then fantasy is fantasy after all.

When the South Korean won was still processing monocrystalline silicon, the Huaguo Chinese Academy of Sciences held a press conference.
