Chapter 282: Simple solution

Sun Kai heard that Wang Rongzhe said that he could use simple methods to solve the difficulties encountered in photolithography processing.
He immediately asked respectfully, "Professor Wang, this problem has troubled us for a long time. Can you tell me your solution in detail?"
Sun Kai's attitude is very polite. He has been troubled by these issues for a long time. With so many researchers in the project team, no one can think of a good way to solve this problem.
Li Hao's eyes are also on Wang Rongzhe. He thinks that the first problem only needs 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 belong to academic researchers.
However, after more than ten years of research work, especially in times of difficult funding. If I want to develop something, I must use a low-cost and simple method to achieve my purpose.
This made me accumulate a lot of soil methods, they don't look so tall. But it can completely solve the problem.
The few solutions I am going to say are just the solutions that I first thought of based on my own experience, without careful thought. You can choose to absorb.
It's also good to inspire your thinking. "
Wang Rongzhe did not directly explain the solution, and first explained his situation to Sun Kai. Add some convincing power.
Sun Kai immediately respectfully said: "Professor Wang, please state your point of view. We will definitely experiment seriously."
"You're welcome. Your lithography machine will be successful soon. I can also see that the chips I developed have reached millions of households." Wang Rongzhe said politely.
He then explained his solution to Sun Kai.
"The first problem with insufficient control accuracy, I think this should be the chip performance of your lithography machine.
Process large-scale data in a short time, unless you connect a supercomputer to each lithography machine. But this is totally unfeasible, not to mention other difficulties, even the use cost is unacceptable.
My opinion is to use a smart chip, which has a memory function. It also has certain intelligent processing capabilities.
It can make a decision in advance based on the data detected by the sensor. I think you must have done the same, and use ordinary servers to determine in advance.
But you have not been successful. The difference between these two options is that the speed of information transmitted by ordinary servers is very long, but our smart chips respond instantaneously. "
When Sun Kai heard Professor Wang Rongzhe's first question, he replied with surprise: "Professor Wang, your prediction is accurate. If you weren't working in the project team, I would have thought you had seen that situation.
But you said you want to use smart chips. This is not a chicken or egg problem.
Without smart chips, this problem cannot be solved. Without solving this problem, smart chips cannot be manufactured.
How did I feel that he was in an endless loop and couldn't think of a way to unlock him. "
Li Hao couldn't stand it, he directly reminded: "To learn to be flexible, our project team has not processed a large-scale intelligent chip through a simple lithography machine.
It is entirely possible to replace the chip of the mechanical control center with that large intelligent chip. It does not affect the work of other components. "
"This is really simple, I think it over. Professor Wang, you keep talking." Sun Kai said with apology.
Wang Rongzhe erected and said with confidence: "The second question about the laser holder, I think the laser light source needs to be moved during the processing of the smart chip.
But you don't have a good way to make them follow a specific trajectory. "
After seeing Sun Kai nodding his head, Wang Rongzhe continued: "Everyone who has studied physics knows that forces can be synthesized and decomposed. Light can also be decomposed into seven colored lights.
Since you cannot operate the light source of the superimposed laser on a specific trajectory. Then why can't we decompose this trajectory.
A stand containing multiple superimposed lasers is made. Each superimposed laser is responsible for a short section of the decomposed path.
I would like to have our smart chip control. The combination of this decentralized path is not much different from the overall path. "
After listening to Professor Wang Rongzhe's solution, Sun Kai patted the table with his hands, and said sadly, "This solution is too simple. Why didn't I consider such a simple solution.
Through my careful consideration just now, this method can completely solve the problem of the stacked laser bracket we encountered. "
Wang Rongzhe said with a smile: "Some methods of solving problems seem to be simple. But the most important thing is to think of this solution. In addition to having a flexible brain, it also requires some experience.
I have some understanding of your project team, most of them are young people. They are very enthusiastic about exploring new technologies, but relatively speaking, their experience is certainly not as rich as that of established scientific researchers.
Especially our generation, in the process of scientific research, hardly suffered. I think of high technology, which means to express myself, but forget that in some aspects, simple and practical is the most important quality. "
After hearing this, Professor Li Rongzhe applauded excitedly. It is estimated that this is also the experience that Professor Wang has studied hard for so many years and summarized.
Wang Rongzhe directly asked Sun Kai: "The third difficulty of your company, I have little information now, and I cannot make an effective judgment.
I first need to understand the problem, since this grating material can selectively pass through the light source. Could he then become transparent instantly, without blocking any light source. "
"I don't really understand this situation. I immediately asked Guo Jianyu, the director of the Materials and Chemistry Laboratory ~ EbookFREE.me ~ Sun Kai immediately answered when Wang Rongzhe asked.
After seeing Sun Kai's words, he immediately sent Guo Jianyu inquiring information. After a while, he knew the exact answer.
Use a light curtain to show this answer, and only see the performance of this material as an animation on a virtual light curtain.
The amount of current controls the changes inside the crystal of this material. The difference in the internal crystal structure can change the properties of the light source through this material. When the current is increased, the entire material becomes completely transparent.
After looking at Wang Rongzhe, he raised his head confidently and said, "Understanding the specific properties of the material, I suddenly had a solution to this problem.
He and the solution to the second problem are very similar. When I saw that this material changed, the current left to change the form was very short.
Not to mention that it is too late to choose the best solution, and after changing the state, it passes through different light sources. It is that the chip is shielded during the change process, so that the laser is interrupted in a very short time, which also greatly enhances the emergence of the reject rate.
But I found that by making this material transparent, the reaction was very rapid and completed almost instantaneously.
In this way, you can use this material to superimpose, and what kind of grating you want to use, you can directly activate the corresponding composition. This problem is not solved easily. "
Li Hao applauded again after listening. He deeply admired the wisdom of Professor Wang Rongzhe.
