Rebirth: From Internet to the Sea of ​​Stars

Chapter 367

When he was busy, Su Cheng did not forget one thing.

That is the research of extreme ultraviolet lithography machine. Now it really has entered a period of rapid development. It should be known that the previous Asme was only engaged in research in 12 years, and the results were also in the next few years.

Prior to this, whether it was a five-star or other company, they were not very optimistic about this area. At that time, the international mainstream was duv, not euv.

List the data:

One of the core components of the exposure system is the UV light source.

Common light sources are divided into:

Visible light: g line: 436nm

Ultraviolet light (UV), i line: 365nm

Deep ultraviolet light (DUV), KrF excimer laser: 248nm, ArF excimer laser: 193nm

Extreme ultraviolet light (EUV), 10~15nm

It can be said that the research of deep ultraviolet light will not lag behind in the current 5-7 years at least, but the development of science and technology is very fast.

The fourth-generation lithography machine, in comparison, the gap is not too big, domestic efforts can still keep up with the international mainstream, but to the fifth-generation euv, it is completely different.

To know that the fifth-generation lithography machine requires a lot of top materials, let’s look at a set of data. In the previous life, in 2011, 32% of the most critical core materials in the world were completely blank in China, and 52% needed to be imported. Add up 310 to 84%, which is still 2011.

In this case, how to manufacture the fifth generation lithography machine? If there is no breakthrough in the material field, it will always be controlled by others.

With Su Cheng’s efforts, various companies have worked hard to tackle 46 kinds of materials. Of course, although they have not yet been fully formed, two years have passed, and the results are in sight.

In addition, Neon acquired or exchanged some technologies, and in this way 39 core materials were acquired.

The other 27 core materials are located in the cornerstone semiconductor laboratory. Some of this part is basically difficult, and some have relatively poor economic effects. This part is responsible for this part.

The importance of the underlying core materials is unquestionable, so Su Cheng spared no effort to do this, just like the sentence:

It is better to have a father and a mother than yourself!

Buying is not as good as renting. If you didn’t just focus on pressure to grow mushrooms, it would have been a mess now. The pressure of war has always been on your head. You don’t have strong power. What can you do to protect your people? .

The same is true for science and technology. If you don’t increase your technological strength, in modern times, you are being colonized by high-tech countries.

Only if you control the core technology, then no matter what kind of situation changes, everything will not change, and the momentum will get better and better, the Matthew effect is not only in the economic field.

When it comes to materials, one has to talk about the research of deep ultraviolet light. There are three ways to obtain coherent light of deep ultraviolet light: synchrotron radiation source, excimer laser and solid-state laser frequency doubling crystal.

Only domestically has successfully manufactured solid-state laser frequency doubling crystals, and it is also the only country in the world that can manufacture deep-ultraviolet solid-state lasers.

The domestic laser technology is truly unique, the world’s leading level, this technology can be applied to many fields, such as: the fifth-generation lithography machine.

We must know why Lao Mi did not allow Asim to export its lithography machines to China because of concerns that after the lithography machine is available, the country will use laser technology to push the lithography machine forward by one generation, that is, the sixth generation of lithography machine technology. Then they are really going to be dumbfounded.

Because of laser technology, that is really the only one!

At the same time, while Su Cheng did these things, he also submitted a list of banned exports to it.

All of the above materials and resources are available, and most of them are the bottom core of high-precision industries. It is because the above is too generous, so that foreign countries can not only use our research and development, but also get the latest information.

Not to mention dreams, this is true in some fields, of course there are only some fields, and most fields are slightly ahead of foreign countries.

But after Su Cheng came, at least in the semiconductor field, half of the world has caught up with the level of the same period in the world. There is still a small part of the world leading, and the remaining part is trying to catch up.

This is also the reason why Su Cheng put the time point around 2011, because at that time, we can truly say that the localization and industrialization can be completely localized.

Even so, we can only say that we are not behind. In case foreign countries make any new breakthroughs again, oh, then we will be behind again.

For Su Cheng, this financial crisis is an opportunity to make the domestic breakthrough to the international level in one fell swoop.

Even if some time is wasted because of the absorption and digestion, as long as they can digest them completely, then even if they make new breakthroughs, there is nothing to fear.

Su Cheng also has a research and development team, and the country has its own research institute, isn’t it just a matter of spending money on research?

Who is Su Cheng afraid of in this item?

At the same time, a number of export ban lists also contain some materials that are lacking in China, such as rhenium!

But this one, Su Cheng has solved the problem.

For mining equipment, rare metals are purchased at the first time. Its absorption and transformation equipment is the same no matter what the mine is. It is nothing more than some mines that need to be refined for a longer time.

On the basis of the first batch of mining, Su Cheng targeted these precious minerals. Many of these precious minerals are scarce in the world. Naturally, it starts with the most precious and most valuable products in the future.

Therefore, after the various mining equipments were put in place in May, the first batch of domestic refined ore for the Games was these precious minerals. If purchased, it would be a sky-high price, but in Su Cheng, it would be the price of cabbage.

But fortunately, after all, Su Cheng still owes $20 billion, so he can use the money to settle the account. Su Cheng does not matter. After all, it is just oil or ore that will be shipped back in the future. Maybe one month will be enough to pay off the account.

You see, those countries with such rich mineral resources are so lucky! To lie down and make money, as long as the device is activated, money is flowing.

Under such circumstances, Su Cheng formally included the core level. In the next two years, the precious minerals will be mined in key mining areas around the world. Of course, they will not forget to mine iron ore.

Those cherished ores in China will naturally be banned from exporting. If there are any, it cannot be revealed. It is the best choice to keep one hand.

Under this situation, a mining equipment traveled all over the country in more than a month, and then a resource map that was too detailed to be detailed came out.

It shows where there are any mines, how many reserves, etc., anyway, things are much simpler.

And there is also a mining equipment in North Korea. Aren’t they confident because of abundant resources? Then take them out, the same is true for Laomi, and the same is true for Australia.

You must know that mining equipment can go deep into the seabed, and naturally it can go deep inland, and go directly to a few kilometers underground to start mining, and then little by little only the thin layer above is left.

When they finished mining one day, they suddenly discovered that there was no more below. They should be desperate at that time.

Su Cheng just wanted to laugh after thinking about it. .
