"The host has completed the optimization according to the given ideas."

The sound of the system sound brought Lin Xiao back to his senses.

[Mechanical Overall Optimization Guidance] allows him to select a mechanical instrument and then optimize it as a whole.

At the same time, if he has his own ideas, he can optimize according to the given ideas while achieving the target function.

Of course, this idea must be reliable. It cannot be unreliable. If it is not reliable, the system will be optimized according to the default method. As for the default method, it means not changing the fixed logic and following the formula of mechanical instruments.

The working logic is optimized.

For example, the working logic of an EUV lithography machine is to use extreme ultraviolet light, which is reflected by more than a dozen lenses, then passes through a photomask, and finally shines on a silicon wafer evenly coated with photoresist to perform exposure and etching.

, manufacturing chips.

And if you switch to an X-ray light source, then X-rays are used. They don’t need to be reflected by dozens of lenses, and there is no need for a photomask. Instead, they only need to go through a polished crystal and use the X-ray diffraction effect.

, thereby achieving magnification and reduction of X-rays.

X-rays can only use direct writing lithography, and cannot use projection lithography like EUV lithography machines. The main reason is that there is no lens in the world that can amplify and reduce X-rays, and the penetrability of X-rays

too strong.

The wavelength of X-ray is lower than 10nm, or even lower than 1nm, and this wavelength is extremely small, and the gaps between the molecules and atoms of the current lens materials are large, and they will pass directly through the atomic gap, even if

It is still inevitable that some of them will be absorbed, but the energy of the X-ray itself is large enough, so it can pass directly through it, so the current lens cannot condense and amplify it through reflection.

This is why X-rays can be used to detect the internal conditions of the human body. That is, X-rays directly pass through a person's clothes, epidermis, and muscles. The atomic gaps in these structures are large enough to allow X-rays to pass through, and bones contain more

The density of calcium and metal elements is relatively high, and the atomic gaps are relatively small, so X-rays cannot easily penetrate, but are absorbed by the metal elements, so the appearance of bones will appear on CT films.

Of course, X-rays are harmful to the human body for this reason. When they penetrate the human body, part of the energy will eventually be absorbed by the electrons of the internal atoms, perhaps by one of the electrons in the DNA double helix structure in a certain cell.

The base pairs are absorbed by the atoms, and the electrons inside the atoms transition, causing the base pairs to change, which in turn causes the DNA to mutate, and finally leads to its transformation into cancer cells. Of course, it doesn't matter if you take the film once or twice, because fewer cancer cells will be

Immune cells are killed, and in those who stay for a long time, the number of cancerous cells in the body increases, and the immune system cannot keep up, so the number of cancer cells increases, forming cancer.

However, X-rays can be reflected internally due to crystal diffraction, thereby amplifying and reducing them, and then use this method to perform large-scale lithography.

Of course, this is something that others may find unbelievable.

The advantage of X-ray in the lithography machine is that it has almost no diffraction effect and good collimation, while other lights are more likely to be diffracted. Even if there is a slight oxygen molecule passing by, other lights will pass by.

When, for example, when it passes between two oxygen atoms of this oxygen molecule, a similar situation such as single-slit diffraction will occur, resulting in the emergence of a diffraction effect, which ultimately affects the actual photolithography pattern.

This is why a vacuum must be maintained inside the lithography machine.

So if X-rays cannot be reflected by lenses, EUV light and the like would not be considered at all.

This is why diffraction is said to be the natural enemy of photolithography machines.

But now Lin Xiao's idea is to go in the opposite direction. Instead, he wants to use the diffraction effect to achieve his purpose.

Of course, what he has to do is control diffraction.

Well, now a problem arises.

"If you want to control diffraction, you must know why diffraction occurs! And what the rules of diffraction are."

Lin Xiao's eyes flashed slightly.

Today's physicists can still only obtain some diffraction laws through experiments, such as single-slit diffraction, double-slit diffraction, circular hole diffraction, etc.

No one understands the specific cause of diffraction, and it is still an unsolved problem in physics.

And this problem involves wave diffraction.

Diffraction of waves can be divided into classical waves and light waves. Classical waves are caused by the tremor of particles colliding with each other due to the propagation of energy. The phenomenon of trajectory deflection will occur due to collision with obstacles. The diffraction of light waves belongs to the category of quantum mechanics. Specifically,

It cannot be understood using traditional methods, but only through probability and statistics.

To clarify this problem, more and more complex calculations are needed. In addition, more powerful wisdom is required.

Because, this problem is facing [wave] directly!

This physics is full of mysterious fundamental elements.

What exactly is it?

Is it communication from different dimensions, or is it a string played by God?

Although Lin Xiao does not want to reveal the nature of waves, just a property of waves, he believes that this is a problem no less important than multi-dimensional field theory.

Thinking of this, Lin Xiao suddenly felt full of challenges.

"Well, it seems that there will be a lot for me to study in the next period of time."

It is equivalent to saying that he is now entering into theoretical research again.

And this is also necessary.

Because if he didn't study this theory, he wouldn't know what kind of diffraction is required to control X-ray diffraction.

In this way, he doesn't know which crystal structure is most suitable. This means that he has to try his luck, experiment with various crystals, and then tentatively approach the final goal.

He doesn't like to take chances, so he has to start from the source.

"Well, we'll discuss this later. Let's first see what this optimized lithography machine looks like."

Instead of thinking about wave diffraction, he focused on optimization solutions.

"Open the optimized guidance plan."

As his order was issued, a brand new photolithography machine appeared in his mind.

X-ray lithography machine.

Its size is smaller because it does not have a complicated optical path system, so this part of the structure is saved, while other main structures are still there.

However, some subtle changes have occurred inside.

This optimization is an overall optimization, and naturally every part has been optimized, including the arrangement of components and the use of space.

Lin Xiao was amazed by these optimizations, especially this optimized structure, which also has a very important impact on accuracy.

The more streamlined the process, the smaller the error and the higher the accuracy.

This optimized structure achieves the same effect with almost the minimum amount of materials.

This alone made Lin Xiao feel very satisfied.

If such a streamlined structure were shown to Dawson Edinson, he would probably spend 100 million to buy it. After all, the simpler the structure, the more convenient and lower the production cost for them. And

The production cycle is also shorter - which means a lot of money can be made.

Of course, selling it to him was impossible.

Doesn’t it smell good when you use it yourself?

Soon, I reviewed the entire optimized structure, and the next step was to notify everyone in Huaxin Alliance.

He got up and came outside the office.

"Professor Lin!"

When Luo Ming saw him coming out, he immediately shouted.

"Yes." Lin Xiao nodded and said, "Send a message to everyone in Huaxin Alliance. I need to hold an important meeting."

"Set the time...in two weeks, right here at the research institute, and let them arrange for someone to come over who can represent their company."

"OK."

"Um."

Lin Xiao nodded slightly.

Two weeks should be enough for him to conduct a preliminary study on diffraction.

Now, they have been sanctioned again, and X-ray lithography machines have undoubtedly become a perfect way out.

Then he will have greater confidence in convincing these people.

"By the way, do me one more favor."

"You say."

"Investigate the current situation of that FBI undercover, Philip Meng's family."

"That undercover?" Luo Ming was stunned.

"Yes." Lin Xiao nodded.

In fact, he wanted to transfer some money to Philip Meng's family every month, but he was worried that the FBI would find out if he transferred money from his Chinese account to his family, so the matter could only be postponed, at least until

Let’s talk about this after this incident has passed.

But Luo Ming was a little confused as to why Lin Xiao did this.

Could it be that that undercover agent has something to do with Lin Xiao?

Luo Ming thought for a moment and was suddenly shocked.

When Lin Xiao didn't go to receive the Wolf Prize, it seemed like he was reminded?
