From Almighty Scholar to Chief Scientist

Chapter 261 Lithography machine assembly plan

After reading this letter, Lin Xiao was slightly moved.

From between the lines, he could see the old man's excitement.

Of course, for such old aviation people, they should be so excited that the J-[-] can make such a huge progress.

The performance of the TA1000 is so strong that it is of course the strongest in the world among all the materials used for turbofan blades. Otherwise, the J-[-] would not be able to fly so fast.

The stronger the heat resistance of TA1000, the greater the increase in thrust. After all, every 100 degrees Celsius increase in the temperature before the vortex can increase the thrust by 10%-25%. As the key material for bearing this temperature, the turbo blade is the key material for TA1000. Doubt is very strong.

In this regard, Lin Xiao, as the developer of TA1000, is very clear in his heart.

Because of what Academician Gu Song quietly said to him at the National Science and Technology Awards Conference, he has been paying attention to the matter of J-[-]'s limelight these days.

Seeing such a powerful performance of the J-[-] also made him feel that the truth points spent at the beginning were worthwhile.

Then he put the letter aside and opened another letter.

This letter is a local letter, that is, it was sent from Shangjing.

Lin Xiao did not know the sender.

However, when he opened the envelope and took a look, he couldn't help being surprised that it was actually a letter of thanks from an air force general.

The general's writing seems clean and neat.

[Professor Lin Xiao, thank you very much for your work, but since it is not convenient to meet, I can only write a letter to express my gratitude to you.

When Haiyan and rivers are clear and the mountains and rivers are peaceful, I will thank you in person. Of course, maybe I won’t see this day anymore, but I can still do it after I retire.

Hahaha……】

After reading the letter, Lin Xiao smiled again.

Haiyan Heqing?

He believed that such a day would come.

And he is working hard on it.

Putting the two letters aside, he turned his gaze to the screen in front of him again.

All I saw on the screen was a crystal structure connected by countless spheres representing atoms.

The structure of these atoms is very strange, but if you look at it, you will find the rules. If you look at one of its crystal planes, you will find that the atoms on each crystal plane are misplaced.

And this is a crystal structure that can magnify and shrink X-rays that Lin Xiao obtained after studying for so long and after careful calculations.

Of course, this is only the result of his calculations, and now it is still necessary to determine its actual effect through simulation.

"Well, now it's time for the simulation."

From the software, I found the option representing X-rays, and then started to set the direction, angle, and wavelength of X-rays.

According to his previous calculations, to better play the role of diffraction, the wavelength of X-rays should not be too small, otherwise, X-rays with too small wavelengths have stronger penetrating performance, and it will be even more difficult to control their diffraction .

Therefore, the wavelength of X-ray should be 3.56nm.

And this uses the diffraction effect, so it cannot be irradiated vertically like EUV light, but requires an angle, which is precisely the need to control the magnification and reduction of X-rays by controlling the incident angle of X-rays.

"Well, let's start with a 30-degree angle of incidence."

After inputting a few data, a thick dotted line representing X-rays appeared on the three-dimensional coordinate system in front of me. Through the process of diffraction, the thick dotted line is decomposed into several dotted lines during the diffraction process, and then penetrates inside continuously until finally, it penetrates the crystal and finally forms a larger irradiation surface.

Seeing this scene, Lin Xiao smiled slightly.

Not bad, just like in the calculation.

When the incident angle is less than 57.5 degrees, the X-ray can be magnified, and when the incident angle is greater than this angle, the X-ray will be reduced.

This magnification and reduction does not refer to the magnification and reduction of the wavelength of the light, but the magnification and reduction of the radiation range of the X beam, just like focusing or diffusing with a magnifying glass under the sun. This is a truth.

In this way, X-ray has the capability of mass production.

Then, he continued to test, by adjusting the crystal structure to change the angle of incidence, and then realize the magnification and reduction of X-rays.

After many tests, it has been confirmed without a doubt that this crystal structure has reached the level he needs.

So, the question now is, how to produce such crystals!

He has already selected the element of this crystal, and it is still silicon.

The number of electrons in the outermost shell of silicon is 4, which means that its plasticity is very strong. Although it cannot form a variety of allotropes like carbon, it is not impossible to achieve such an effect through process design. To a certain extent, in condensed matter and materials science, there is a concept called amorphous. Amorphous silicon does not have an extended lattice structure like crystalline silicon, and the lattice network between atoms is arranged in disorder. Using this principle, further According to the special process design, the structure that Lin Xiao wants can be achieved.

As for why carbon is not selected, it is because carbon atoms are too small, even if 10nm X-rays are selected, they may easily pass through the lens synthesized by them, so silicon is the most suitable.

But judging from the current results, they succeeded.

"Well, it seems that in the next period of time, I will go to the laboratory frequently again."

With a slight sigh in his heart, he glanced at Mimi who was still sleeping next to him and never knew what work was. Lin Xiao couldn't help but reached out and rubbed it.

"You cat repair, you're so lazy."

Mimi was awakened by his rubbing, "meow", raised her head slightly to glance at Lin Xiao, then rubbed against his palm, then turned over, revealing her furry belly.

Lin Xiao chuckled, but out of the corner of his eye, he caught a glimpse of the letter from the air force general next to him.

The surrounding sea is not clear, the inland river is not clear, still need to work hard.

With a fixed gaze, he took out his mobile phone and made a call: "Zhao Sheng, the new model we built a few days ago has been perfected by me in the past few days, and it has met our requirements. According to the calculation of the simulation program, it can reach Our requirement!"

Zhao Sheng is a domestic computational materials expert he recruited at the beginning, and he is a professor in the Department of Materials of Tsinghua University.

Having said that, he poached a lot of people from Beijing University and Qinghua, and he didn't know if they would be angry.

Well, let's talk about this matter later, he doesn't care if he is angry or not.

At this time, Zhao Sheng's surprised voice sounded on the phone: "Professor Lin, we succeeded?"

"Yes." Lin Xiao said with a smile: "So, at three o'clock this afternoon, call everyone for a meeting, and start our next stage, the design process!"

"it is good!"

Zhao Sheng immediately said excitedly.

After hanging up the phone, Lin Xiao didn't leave immediately.

"The crystal structure is already available, and the X light source is also available. The double workbench is still being developed, but because of the new encoder, the progress is also speeding up."

"These three most critical things have already seen the dawn of success."

"As for the remaining components, there is basically no shortage of domestic technology."

The most critical technology of the lithography machine is the light source system, the optical path, that is, the lens system, and the double-table system, because these three are the most precise structures that the entire lithography machine needs to move and move.

As for the other parts, Huaguo is fully capable of producing them. Even if they are purchased from abroad, there will be no issue of sanctions, because the technical level of other parts is not high. up.

And this calculation means that——

"The plan to start producing parts of various parts and prepare to assemble the lithography machine should also officially start."

Lin Xiao's eyes flickered slightly. Although there are still some technologies that need to be overcome, it takes a long time to assemble the lithography machine. Asmail can only build dozens of lithography machines a year, because the lithography machine Even assembling is a test of precision. After all, slow work produces meticulous work. Even if it is the installation of a screw, it needs to be done slowly.

It is obviously impossible for Lin Xiao to wait until all the technologies are conquered before starting to assemble slowly.

Moreover, in Huaguo, he should also make good use of the advantages of this game of chess.

Just like Huaxin League, he established it with such advantages.

Therefore, it is time for domestic manufacturers to prepare and start assembling lithography machines.

Of course, this matter also requires the cooperation of the above, so that it is convenient for him to mobilize resources from all parties.

It seems that I have to write an internal reference.

With this in mind, he immediately found a piece of paper from the side.

He had to write a letter too.

As for what to write, it is actually very simple.

[The technical breakthrough work of manufacturing the lithography machine has reached the last juncture. Now, the plan to assemble the lithography machine can start. I implore the leadership for research and approval. 】

After finishing writing, he went downstairs to buy an envelope, packed it, and then called Director Ma: "Director Ma, I need to ask you something."

Immediately, Director Ma's excited voice came from over there: "Okay! You say so! Do you want to meet at the old place?"

Lin Xiao was taken aback, why is Director Ma so happy?
But he didn't care, and said with a smile: "No, I just wrote a letter. Of course, the matter is more important. I hope you can pass it on to the higher authorities."

"Letter? OK!" Director Ma said immediately.

Although it is not the usual place to meet, he believes that as long as Lin Xiao asks him for help, it must be a good thing.

He is very experienced now.

What's more, Lin Xiao told him that it was important, and he had to pass it on to the higher authorities.

Then it is even more certain that there will be a great good thing!

He believes in it very much.

So the two made an appointment and hung up the phone.

Lin Xiao also packed up his things and went to the research institute to prepare for a meeting.

　The review secretly blocked me...
