Chapter 284 Another island country with heavy losses
Laser generator, energy controller, light speed controller, optical mirror, mask stage, exposure stage, measuring instrument, shock absorbing device.
The eight core components of the 'mm-level' lithography machine have all been manufactured.

After spending some time figuring out and assembling some of the remaining parts, the parts turned into a container-like rectangular container.

After a series of debugging, testing, and preliminary testing, Won officially announced to the audience in the live broadcast room that the manufacture of this 'millimeter-level' lithography machine was completed.

Looking at the lithography machine in the dust-free studio, Han Yuan felt a sense of accomplishment and satisfaction.

Although he knew that the thing in front of him was just a toy compared to the modern top-level EUV lithography machine, and even the precision of the toy was higher than it.

But the place where dreams start is often very simple.

With this, he can gradually increase the computing power of the computer's computing core. With a computer with higher computing power, he can write programs to manufacture more sophisticated lithography machines.

And with a more sophisticated lithography machine, it can feed back chips with higher computing power, thereby improving the computing power of computers.

Repeatedly, step by step.

And the first step is the hardest step.

Just like starting a business, the acquisition of the first 100 million is often memorable, and people can clearly remember all the hardships they have suffered.

And after you have the basic capital, it will be much easier to develop later, as long as you are on the right path.

The live broadcast room was also full of praise, rubbing the lithography machine with hands, this thing that Nima didn't even think about actually happened in front of her eyes.

Although the accuracy is very different, this does not prevent the audience in the live broadcast room from admiring.

【666666666】

[Awesome, the lithography machine is all out. 】

[Although I know it's not easy, why do I want to laugh so much when I hear the word 'millimeter level'_]

[AMSL ​​sells lithography machines in units of nanometers, and the anchor is millimeters, hahahahahahaha. 】

[Don't laugh, don't laugh, it's really not easy! 】

[The older generation of revolutionaries and builders dedicated their youth, which allowed our country to have the first millimeter-level lithography machine until the 80s. 】

[Remember the history!If you fall behind, you will be beaten! 】

[The lithography machine is our pain, but to be honest, the R&D investment of the entire domestic semiconductor industry cannot match that of Intel. How can we catch up? 】

[The problem is that the country has no money. Although the total GDP is large, the per capita GDP will not be much in an instant. 】

[The money that the entertainment industry randomly steals and leaks is astronomical. It would be great to track it down and invest it in the field of science and technology. 】

[Lianxiang had a chance to get a lithography machine back then, but the result, ε=(ο｀*))) Now everyone can see what happened to Lianxiang. 】

[Is there anyone who scolds Liugou every day and likes it? 】

In the live broadcast room, the barrage transfers topics very quickly, and often one topic is transferred to another topic within 2 minutes of chatting.

After checking the lithography machine, Han Yuan sat on the ground and chatted with the audience for a while, then stood up and said:
"Okay, now that the lithography machine has been prepared, everyone must know what to do next."

Hearing this, the topic on the barrage quickly changed.

Han Yuan smiled, closed the door of the dust-free studio according to the standard procedure, and left the dust-free studio.

"That's right, making chips."

"But there is one more problem I need to solve before making the chip."

Hearing what Han Yuan said, the audience in the studio immediately became confused and asked what the problem was.

After all, now that the lithography machine has been manufactured, can't we start to do it?

Leaving the dust-free studio, Han Yuan braved the scorching sun and walked towards the chemical laboratory. While walking, he explained:

"The lithography machine is used to process chips, and before that, I still need to solve the problem of chip materials."

"As for the materials used to make chips, I have most of them, but I still lack one."

"Single crystal silicon!"

After the Korean won's voice fell, the eyes of the experts and scientific researchers from all over the world squatting in the live broadcast room were bright and slightly disappointed.

Except for a certain island country in the east of China.

Mingliang hopes to see ultra-high-purity single-crystal silicon smelting methods. As for disappointment, it is impossible to see carbon-based chips.

After the anchor mentioned some information about carbon-based chips before, he never mentioned it again.

Although they knew before that after the lithography machine was built, the next step to deal with was the material of the chip.

But before the anchor said it, everyone was still not sure whether he would manufacture monocrystalline silicon.

After all, when the anchor made various tools, he didn't make a single crystal furnace.

Moreover, monocrystalline silicon is not the only choice for chip substrates. If cost and other issues are not considered, there are many other materials that can also replace silicon-based chip substrates.

For example, the silicon carbide crystal material that this anchor has produced before will do.

However, the silicon carbide crystal material he prepared in the chemical laboratory is definitely not enough in terms of purity.

The manufacture of nano-scale silicon-based chip substrates requires that the purity of the substrate crystal material be quite high, such as single crystal silicon, which requires a purity of 99.9999%, or even more than 99.9999999%.

It's not whether the anchor can be processed to this purity, or the pollution in the chemical laboratory during the manufacturing process is enough to prevent the material from reaching this purity.

Therefore, in the absence of single crystal furnaces and conditions to process and manufacture single crystal silicon, the anchor may directly bypass single crystal silicon and use other materials as chip substrates.

Among them, there is a slight possibility of directly manufacturing carbon-based chips.

Although they know that there is little hope, they are still looking forward to it.

As for the preparation of monocrystalline silicon, it is actually not difficult. What is difficult is the improvement of purity and various crystallization problems encountered in the manufacturing process.

These are the difficulties.

At present, there are not many countries in the world capable of producing monocrystalline silicon with a purity of over 99.99999%.

The United States is one, and the island countries are one.

As for other countries, although monocrystalline silicon can be produced, it is still far behind in terms of purity.

For example, in Huaguo, even with a single crystal furnace imported from an island country, the purity of the smelted single crystal silicon can reach at most 99.999%.

It simply cannot meet the requirements for preparing high-end chips.

This is impossible. After all, the single crystal furnace equipment purchased will definitely not be the top.

Just like AMSL, Huaguo can't buy top-level lithography machines even if he has money.

In countries like island countries, not to mention top-level furnaces, even the sub-top single crystal furnaces are not sold, and what they sell are sub-sub-level ones.

Not to mention the expensive ones, there are still a lot of disgusting conditions, such as what cannot be disassembled, what has malfunctioned, and other problems that can only be dealt with by the islanders.

But there is no way, even if you are disgusted, you still have to hold your nose and buy it.

Because there are only island countries and the United States that can manufacture top-level single crystal furnaces in the world.

In the island country, you can still buy it anyway, but the single crystal furnace is simply not sold in the United States.

Even if you know there is shi in your rice, you have to eat it, because if you don't eat it, all domestic manufacturers will have no monocrystalline silicon to use, and they can only choose to go bankrupt at that time.

If technology is backward, people will have to be restricted and beaten. There is no way to do this.

That's why the top management paid special attention to this live broadcast room.

Because from here we can see the hope of technological breakthroughs.

As for a certain island country, when they heard that Korean Won was going to prepare monocrystalline silicon, they immediately became angry. Why did this anchor target them again and again.

The previous ion implanter is the same, and the high-speed disk writing technology is also the same, and the single crystal silicon and single crystal furnace are even more so.

These are their top technology representatives.

There are tens of billions in revenue from exporting monocrystalline silicon and monocrystalline furnaces to the world every year, and it may be gone now.

This loss was huge in an instant.

But getting angry won't solve the problem, unless they can drill into the screen and give the anchor to the gun.

Otherwise it's just impotent rage.

The only thing to do now is to seize the time to discuss countermeasures and pray that the anchor will not be able to produce top-purity monocrystalline silicon.

In that case, they can continue to maintain the status quo and continue to export monocrystalline silicon and monocrystalline furnaces to Huaguo and the world.

With anticipation and apprehension, the people from the island nation squatting in the Korean Won live broadcast room continued to watch the live broadcast, hoping that God Yaqi would bless them.

It's a pity that what they don't know is that their Baqi God is nothing more than a poor eight-headed snake in the mythology system of Huaguo.

Those who can't even enter the fairy class can't protect them at all.

In the simulation space, Han Yuan came to the storage room of the chemical laboratory and took some materials for preparing monocrystalline silicon from it.

As the experts in the live broadcast room said before, when he upgraded his industrial equipment, he did not manufacture a single crystal furnace for smelting single crystal silicon.

But this does not mean that he cannot smelt and prepare single crystal silicon.

With the knowledge and information in his mind, Han Yuan found a better way than the single crystal furnace to smelt single crystal silicon.

"Silicon Core Epitaxy."

This is a preparation method similar to chemical vapor deposition to prepare materials.

Students who are not familiar with the chemical vapor deposition method can refer to the crystallization of saturated sodium chloride solution.

Although the complexity is different, the principle is similar.

Compared with the preparation of single crystal silicon in single crystal furnace, the "silicon core epitaxy method" has many advantages in the preparation of single crystal silicon.

For example, silicon core vapor phase epitaxy can improve the perfection of silicon materials, improve integration, improve the life of minority carriers, reduce the leakage current of storage cells, increase the speed of circuits, change the power characteristics and frequency characteristics of circuits, and solve the locking of CMOS circuits. Etc., etc.
Oh, by the way, the most important thing is the purity of monocrystalline silicon.

The purity of single crystal silicon prepared by 'silicon core epitaxy' can reach more than 99.9999999%.

When Won mentioned the purity of the monocrystalline silicon prepared by the 'silicon core epitaxy method', the nervously watching the live broadcast of the islanders' eyes darkened, and they passed out.

This news is really terrible.

It’s okay to lose tens of billions of meters of gold export revenue every year. If monocrystalline silicon can be produced all over the world, then AMSL’s dependence on their monocrystalline silicon will be able to easily replace suppliers.

This is a loss that they can't even recover.

The "silicon core epitaxy method" has advantages in preparing single crystal silicon, but naturally also has disadvantages.

When silicon core epitaxy is used to prepare single crystal silicon, silane thermal decomposition epitaxy is generally used for processing.

However, silane is flammable and explosive, so the equipment requirements for silane epitaxy are relatively high.

Moreover, silane epitaxy is greatly affected by the purity of silane, and the distribution of impurities in the epitaxial layer is also difficult to control.

Moreover, when using the silicon core epitaxy method to prepare single crystal silicon, the reaction in the reaction chamber is very complicated.

There are many factors that must be considered, such as the wide variation range of deposition parameters, the pressure in the reaction chamber, the temperature of the wafer, the flow rate of the gas, the distance of the gas through the wafer, ..., and whether other external energy sources outside the reaction chamber are required Various conditions need to be taken into account, such as speeding up or inducing the desired response.

Therefore, the silicon core epitaxy method requires more manpower, physics, and harsher conditions than the single crystal furnace to produce single crystal silicon.

But these are nothing to South Korea and Huaguo.

Won has enough technology in his hands, and Huaguo has a huge population.

With the materials for preparing monocrystalline silicon, Han Yuan came to the chemical laboratory, cleaned all the materials and then washed them with distilled pure water.

Minimize the impurities attached to it.

Of course, this is only the first step, and there must be many steps of purification and smelting later.

When the decimal point of the purity of single crystal silicon moves a little further, the difficulty of preparation increases geometrically.

Although the purity of single crystal silicon prepared by 'silicon core epitaxy' can reach more than 99.9999999%.

But this is only a theoretical stage, and he is currently unable to improve the smelting of single crystal silicon with this purity.

The environment and equipment are not up to the requirements. Based on the current situation, it can reach 99.999% at most, but it is enough to make millimeter-scale chips.

After all, the levels are all at the millimeter level, and the requirements are not very high.

After cleaning and processing the raw materials, Han Yuan began to process basic materials and solutions in the chemical laboratory while explaining.

Just like the preparation of the 'distributed Bragg reflector' before, some basic materials that can be processed are processed in the chemical laboratory first, and then transported to the dust-free studio for the remaining steps.

In fact, silicon carbide semiconductor crystals can also be used to manufacture silicon-based chip substrates.

However, South Korean won still chose monocrystalline silicon.

Because even if the silicon carbide semiconductor crystal material is selected as the substrate, it still needs to be purified, and the steps are more troublesome.

In addition, the Korean won knows that in the real world, more than 70.00% of the world's monocrystalline silicon sources are supplied by island countries.

As a feud, Won is perfectly happy to make trouble for the other party.

It's just a monocrystalline silicon. If it's not suitable and there is no time, Han Yuan even has the idea of ​​live broadcasting all the top technologies mastered by the island country.

You must know that although the island country is a small country, it has a lot of top technology in its hands.

Even in many respects, it is not as good as its old father, the United States.

Such as single crystal silicon single crystal furnace, deep sea unmanned detection technology, numerical control robot and so on.

The share in the world is above 70.00%.
