Sun Kai heard Wang Rongzhe say that he could solve the difficulties encountered in lithography machining in a simple way.

He immediately respectfully asked, "Professor Wang, this problem has been bothering us for a long time, can you tell me your solution in detail?" ”

Sun Kai's attitude was very polite, he had been troubled by these questions for a long time. There are so many researchers in the project team, and none of them can think of a good way to solve this problem.

Li Hao also stared at Wang Rongzhe, he believed that the first problem only needed smart chips. With the remaining two, he couldn't think of a good solution.

Wang Rongzhe sat up straight, he looked at Sun Kai, and said with a smile: "At first glance, your project team is mostly academic. I used to be an academic researcher.

However, after more than ten years of scientific research work, especially in the difficult period of funding. If I want to develop something, I have to use a low-cost and simple way to achieve my goal.

This has allowed me to accumulate a lot of dirt methods, which don't seem that tall. But it solves the problem entirely.

The solutions I am about to talk about are just the first ones that I thought of based on my own experience, without careful consideration. You can choose to absorb it.

It is also good to inspire your thinking. ”

Wang Rongzhe did not directly explain the solution, but first explained his situation to Sun Kai. Add some convincing.

Sun Kai immediately said respectfully: "Professor Wang, please state your point of view." We will definitely experiment seriously. ”

"That's kind to say, the sooner your lithography machine succeeds, I can also see the chips I developed go to thousands of households." Wang Rongzhe said politely first.

He then explained his solution to Sun Kai.

"The first problem of insufficient control accuracy, I think it should be the chip performance of your lithography machine.

Short-term processing of large areas of data, unless a supercomputer is connected to each lithography machine. But this is completely unfeasible, not to mention other difficulties, even the cost of use is unacceptable.

My opinion is to use smart chips, and smart chips have memory functions. It also has a certain amount of intelligent processing power.

Based on the data detected by the sensor, it can make decisions in advance. I think you've done the same thing, and use a normal server to determine in advance.

But you must not have succeeded, the difference between the two options, that is, the speed of information transmitted by ordinary servers is very long, while our smart chips are instantaneous. ”

When Sun Kai heard Professor Wang Rongzhe finish his first question, he replied in surprise: "Professor Wang, your prediction is accurate. If you weren't working on the project team, I'd have seen it with your own eyes.

But when you say you want to use smart chips, it's not a matter of chicken or egg.

Without smart chips, this problem cannot be solved. If you don't solve this problem, you can't make smart chips.

How I feel like he's stuck in a dead loop and can't think of a way to untie him. ”

Li Hao couldn't stand it, and he reminded directly: "To learn to be flexible, our project team has not processed large-scale smart chips through simple lithography machines."

It is completely possible to replace the chip in the mechanical control center with that large intelligent chip. It does not affect the operation of other components. ”

"It's really simple, it's not a good idea. Professor Wang, go on. Sun Kai said apologetically.

Wang Rongzhe put up two fingers and said confidently: "The second question about the laser bracket, I think in the process of processing the smart chip, the light source of the laser needs to be moved.

But you don't have a good way to make them move in a particular trajectory. ”

After Wang Rongzhe saw Sun Kai nodding incessantly, he continued: "Anyone who has studied physics knows that force can be synthesized and decomposed. Light can also be broken down into seven colors of light.

Since you can't make the light source of the superimposed laser follow a specific trajectory. So why can't you break this trajectory down?

A scaffold containing multiple superimposed lasers is fabricated. Each superimposed laser is responsible for a small section of the broken path.

I think there is our intelligent chip control, this kind of scattered path combined, it is not much different from a whole path. ”

After listening to Professor Wang Rongzhe's solution, Sun Kai slapped the table with his hand and said regretfully: "This plan is too simple, why didn't I consider such a simple plan."

After thinking about it carefully, this method can completely solve the problem of the stacked laser bracket we encountered. ”

Wang Rongzhe said with a smile: "Some solutions to problems seem very simple. But the most important thing is to think of this solution. In addition to having a flexible brain, this requires a certain amount of experience.

I also know a little bit about your project team, and most of them are young people. They are very enthusiastic about exploring new technologies, but they are certainly not as experienced as established researchers.

In particular, our generation has hardly suffered in the process of scientific research. All I think of is high technology, the means to show myself, but I forget that in some aspects, simplicity and practicality are the most important qualities. ”

When Li Hao heard Professor Wang Rongzhe say this, he applauded excitedly. It is estimated that this is also the experience that Professor Wang has summed up after so many years of hard work.

Wang Rongzhe asked Sun Kai directly: "The third difficulty of your company, I have obtained very little information now, and I can't make an effective judgment.

The first thing I want to understand is that since this grating material can selectively pass through the light source. Then he can't instantly become transparent and not block any light source. ”

"I really don't know about this situation, so I immediately asked Guo Jianhao, director of the Materials and Chemistry Laboratory." When Sun Kai heard Wang Rongzhe's inquiry, he immediately replied.

I saw that after Sun Kai finished speaking, he immediately sent Guo Jianhao to ask for information. After waiting for a while, he knew the exact answer.

Use a light curtain to show this answer, only to see the virtual light curtain animating the performance of this material.

The magnitude of the current controls the changes inside the crystals of this material. The difference in its internal crystal structure can change the properties of the light source passing through the material. When the current is increased to a certain level, the entire material becomes completely transparent.

Wang Rongzhe raised his head after reading it, and he said confidently: "Knowing the specific properties of the material, I suddenly have a way to solve this problem."

He solves the second problem in a similar way, I see that when the material changes, the current that changes the shape is left for a short period of time.

Not to mention the current does not have time to choose the best solution, after reaching the state of change, through a different light source. It is the change process that obscures the chip, so that the laser is interrupted in a very short time, which also greatly enhances the occurrence of scrap rate.

But I've found that when I make this material transparent, the reaction is very fast, almost instantaneous.

In this way, it is possible to superimpose with this material, and whatever kind of grating you want to use, you can directly activate the corresponding composition. This problem will not be solved. ”

After Li Hao listened, he applauded again. He deeply admired Professor Wang Rongzhe's wisdom.
