Chapter 281: Difficulties of lithography machine

Li Hao said with some loss: "It doesn't matter, failure is the mother of success. X We make the finished product for the first time, and failure is normal.

As long as we summarize the experience again and find the cause of this failure, I believe that the smart chip will always meet our requirements. "

After hearing this from Li Hao, Zhu Yanbo asked in confusion: "How do you think this test failed. This test project was a perfect success, even better than we thought.

It makes perfect use of each data and summarizes the precipitation data of the past 20 years in this area. The result is exactly the same as the reality. "

"Success!" Li Hao asked incredulously, "I see that this software clearly gives that the typhoon has not landed, but I read the news reports mentioned in the information, which are information that the typhoon is about to land."

Looking at Li Hao's unbelievable gaze, Zhu Yanbo explained: "The data of this typhoon is the well-known Typhoon Taili. It was about to land in China. As a result, when it was about to land, it made a right-angle bend and ran directly to Japan.

The data analyzed by this software is correct. You can see that the analysis process is given below. From the fluctuation of air pressure, it is judged that there will be a significant change in the typhoon path.

Although the software did not predict the path of the typhoon, it concluded that the typhoon would not land.

This has far exceeded our pre-designed goal. I did not expect that the smart chip has only a weak intelligence, and it can exert such a great effect. "

Wang Rongzhe was rejuvenated, he said happily, "I never expected that the smart chip would achieve better results than I expected. The smart chip microstructure designed by the carbon-based chip clear porcelain technology company, they can really promote each other.

I did not expect that mutual cooperation can play such a big role, and the results obtained by One Plus One are far greater than two. It really surprised me. "

Li Hao also said in surprise: "That said, the chip design work is over and it is ready to start production."

Wang Rongzhe nodded and agreed: "Our lab has been designed in detail, and all obvious defects have been detected. To find the defects of the chip, we can only improve the data through large-scale industrial applications.

The chip is designed to such an extent that it can be completely industrialized. Etching machines and other chip processing equipment have been developed by other enterprises in China, and their performance is at the international advanced level.

Now the equipment for processing smart chips is only short of lithography machines. When your lithography machine project is successful, it is time for mass production of smart chips. "

Li Hao looked at Wang Rongzhe with a relaxed expression on his face. He knows that this is Professor Wang Rongzhe's joy in the successful development of smart chips.

In the field of chips, his responsibility has been fulfilled. Whether the remaining chips can become industrial products depends on whether Huaxia's industrial processing field can meet the requirements.

Li Hao saw that Zhu Yanbo was collecting the data just tested. He knows that today's chip test work has been basically completed.

He invited Professor Wang Rongzhe: "Professor Wang, you just came to this laboratory. Let's go and see the progress of the lithography machine."

Wang Rongzhe was also very concerned about the current progress of the lithography machine. He immediately agreed with Li Hao's invitation.

Before leaving, Wang Rongzhe ordered Zhu Yanbo to collect all the test data of the smart chip. After letting him collect the data, he can go back to school directly.

Li Hao took Wang Rongzhe to the office of Sun Kai, the person in charge of the lithography project.

Now the daily management of the electronics company has been given to his deputy. He is in charge of the R & D of the lithography machine.

They knocked gently on the door and walked into this office.

Through his special glasses, Li Hao can see that Sun Kai is learning the knowledge of lithography machines and chip production.

This is really learned from old to old, and knowledge is endlessly useful. I did not expect Sun Kai to work so hard to gain knowledge.

Li Hao saw that he had recovered a little bit, and was much thinner. It is estimated that the pressure on him after hosting the lithography machine project is great.

Sun Kai saw Li Hao and Wang Rongzhe enter his office. After inviting them to sit down, they asked with a smile: "Mr. Li, is there anything you are doing this time?"

Li Hao directly asked: "I want to know the progress of the lithography machine project, especially the obstacles that the lithography machine project is blocked by.

It is because our company's scientists can't solve it, I will try to find ways to ask the Chinese Academy of Sciences and other research institutions to let them help us solve this problem. "

"This is really good. We haven't made breakthroughs in several technologies. I will report to you." Sun Kai said with joy.

He immediately pointed out the difficulties encountered in the lithography machine project.

After Li Hao listened, he summarized the difficulties encountered by the company. There are still two main gaps. One is the material aspect, and the other is the control system.

The control system is mainly fine control, which cannot meet the requirements. The precision of the chips they process is controlled to one nanometer. This is also slightly larger than the atom. Any unresponsiveness of the control system will have catastrophic consequences.

However, the information processing speed of the lithography machine control system can not meet the requirements. The sensor information must be received, then judged by the system, and then transmitted to the control mechanism of the lithography machine.

The entire feedback takes too long, mainly because there is no advanced chip, which forms the core of the control system. As a result, the lithography machine failed to process the chip.

This point can also be solved by technical means. Li Hao can now think of a way to use smart chips here.

Through the experiment just made by Wang Rongzhe ~ www.readwn.com ~, he knows that smart chips will definitely solve this problem.

The second difficulty is the material problem, because the lithography machine they designed is mainly for carbon-based chips.

Its structure is still different from ordinary lithography machines. The most critical thing is to set up a bracket for the superimposed laser.

This stent design index is for the laser to perform various actions. He must be more flexible than a human finger and the reaction time should be as short as possible.

The structural design of the bracket has been solved through the joint efforts of the project team's scientific researchers, but it requires a material with a friction coefficient as small as possible, and no ideal material has yet been found.

This is just a common hurdle encountered by the lithography machine project. Li Hao feels that these problems will be resolved sooner or later as time develops.

The most difficult problem is the grating material. Guo Jianzheng has now developed a stable grating.

However, it has a characteristic that it is necessary to control the change of the crystal structure inside the grating within a short time after exposure.

This requires extremely fine current excitation to solve the problems caused by the crystal structure, which places high demands on the control system.

If it is unsuccessful, the effect of the crystal structure inside the grating cannot be solved, then its effect of controlling the light path will also be invalidated, and the entire chip cannot be processed.

Wang Rongzhe heard Feng Kai finish, and he suddenly interjected: "The solution to these problems is very simple. As for bothering you for so long." Rw
