Chapter 281: Lithography Machine Difficulties

Li Hao said with some loss: "It doesn't matter, failure is the mother of success." The first time we made a finished product, failure was normal.

As long as we sum up the experience again and find the reason for this failure, I believe that the smart chip will always meet our requirements. ”

Hearing Li Hao say this, Zhu Yanbo asked suspiciously: "How do you think that this test failed." The test project was a perfect success, even better than we thought.

It makes perfect use of every piece of data to summarize the precipitation data for the region over the last 20 years. The result is exactly the same as the reality. ”

"It worked!" Li Hao asked in disbelief, "I see that this software clearly gives that the typhoon has not made landfall, but I read the news reports mentioned in the data, all of which are information that the typhoon is about to make landfall." ”

Looking at Li Hao's incredulous gaze, Zhu Yanbo explained: "The data of this typhoon is the well-known Typhoon Taili. It was supposed to land in Japan, but when it was about to land, it turned a right-angled bend and ran directly to Japan.

The data analyzed by this software is very correct, and you can see that he has already given the analysis process below. Through the fluctuation of air pressure, it is judged that there will be a significant change in the path of the wind.

Although the software does not predict the path of the typhoon, it concludes that the typhoon will not make landfall.

This has far exceeded our pre-designed goal, but I didn't expect that the smart chip only has a weak intelligence, and it can play such a big effect. ”

Wang Rongzhe was in good spirits, and he said happily: "I really didn't expect the smart chip to achieve better results than I expected." The microstructure of the smart chip designed by the carbon-based chip Qingci Technology Co., Ltd. can really promote each other.

I didn't expect that the cooperation with each other could play such a big role, and the result obtained by one plus one was far greater than two. It really surprised me. ”

Li Hao also said pleasantly: "In that case, the chip design work is over, and the finalized production can begin." ”

Wang Rongzhe nodded and agreed: "After detailed design, our laboratory has detected all the obvious defects. If you want to find the defects of the chip, you can only improve it by collecting data after large-scale industrial application.

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

Now the equipment for processing smart chips is only lacking lithography machines, and when your lithography machine project is successful, it will be the time for large-scale production of smart chips. ”

Li Hao looked at Wang Rongzhe with a relaxed expression. He knows that this is Professor Wang Rongzhe's joy for the successful research and development of smart chips.

In the field of chips, his responsibilities have been accomplished. Whether the remaining chips can be turned into industrial products depends on whether Huaxia's industrial processing field can meet the requirements.

Li Hao saw that Zhu Yanbo was collecting the data he had just tested. He knows that today's chip testing work is almost complete.

He invited Professor Wang Rongzhe and said, "Professor Wang, it just so happens that you have come to this laboratory. Let's take a look at the progress of the lithography machine. ”

Wang Rongzhe was also very concerned about the current progress of the lithography machine, and he immediately agreed to Li Hao's invitation.

Before leaving, Wang Rongzhe instructed Zhu Yanbo to collect all the test data of the smart chip. Let him go straight back to school after collecting the data.

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

Now the day-to-day management of the electronics company has been handed over to his deputy. He is in charge of the overall research and development of lithography machines.

They knocked lightly on the door and walked into the office.

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

This is really learning and living to old age, and knowledge is infinitely useful. I didn't expect Sun Kai to work so hard to absorb knowledge.

Li Hao saw that the top of his head, which had recovered a little, was much thinner. It is estimated that after presiding over the lithography machine project, the pressure caused to him is very high.

Sun Kai saw Li Hao and Wang Rongzhe enter his office. After inviting them to sit down, he asked with a smile: "Mr. Li, is there something you have come here for this time?" ”

Li Hao asked directly: "I want to know the progress of the lithography machine project, especially what difficulties the lithography machine project is hindered by."

Even if the scientists in our company can't solve it, I will try my best to find a way to turn to research institutions such as the Chinese Academy of Sciences and let them help us solve this problem. ”

"It's great that there are a few technologies that we haven't been able to break through. Let me report back to you. Sun Kai said with joy on his face.

He immediately spoke out about the difficulties encountered in the lithography project.

After Li Hao listened, he summarized the difficulties encountered by the company. There is still a gap between the two aspects. One is the material aspect, and the other is the control system.

The control system is mainly fine control, which does not meet the requirements. They process chips with an accuracy of one nanometer. This is slightly larger than an atom, and any bit of unresponsiveness in the control system can have catastrophic consequences.

However, the information processing speed of the lithography machine control system is not up to the requirements. The sensor information must be received, and then the system will judge it and then transmit it to the control mechanism of the lithography machine.

The whole feedback takes too long, mainly because there are no advanced chips that form the core of the control system. Causes the lithography machine to fail to process the chip.

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

Through the experiment done by Wang Rongzhe just now, he knew that the smart chip would definitely solve this problem.

The second hurdle was the material, as the lithography machine they designed was mainly for carbon-based chips.

Its structure is still different from that of ordinary lithography machines. The most important thing is to set up a bracket for superimposing lasers.

The design index of this stent is to let the laser do all kinds of movements, he must be more flexible than a human finger, and the reaction time must be as short as possible.

The structural design of the bracket has been solved through the joint efforts of the project team researchers, but it requires a material with the smallest possible coefficient of friction, and the ideal material has not yet been found.

This is just an ordinary difficulty encountered in the lithography machine project, and Li Hao feels that with the development of time, these problems will be solved sooner or later.

The most difficult problem is the grating material. Now Guo Jianhao has developed a stable grating.

However, it has the characteristic that the crystal structure inside the grating must be controlled for a short period of time after exposure.

This requires extremely fine current excitation to solve problems arising from the crystal structure, which is very demanding on the control system.

If it is not successful, the effect of the crystal structure inside the grating cannot be resolved, and its effect on controlling the optical path will also fail, and the entire chip will not be able to complete the processing.

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