After all, this thing was born in 1974. Afterwards, it has been continuously optimized and upgraded by 1445 Institute, and its functionality is still complete. How do you mess with it? Are you still using manual alignment?

This actually involves his knowledge blind spot.

Hearing his question, Qiu Mai was equally surprised:

"Ah? Don't you know? That's right, you probably won't pay too much attention to this."

"But now our alignment system is really poor. The 1445 Institute has experimented with many methods before, but they have not solved the problem of automatic alignment - similarly, the accuracy is not enough."

"1445 does not use the coaxial + off-axis dual alignment method?"

Chen Nian was greatly surprised. For some reason, this thing had been widely reported in his previous life. Even a layman like him had seen a lot of it. He thought that the problem of alignment systems had been solved long ago in China.

"No, off-axis alignment is technically very difficult and the design principle is relatively complex. We haven't figured it out yet."

“This thing is complicated??”

"I can accept that it is difficult to manufacture, but the principle is complicated. Isn't it the principle of light diffraction?"

As soon as he finished speaking, an idea suddenly flashed in Chen Nian's mind, and he remembered more details about the reports he had read before.

yes!

The earliest off-axis alignment technology was invented by ASML in 1999 and was officially used in 2001. The coaxial + off-axis technology that I mentioned appeared in 2007.

At present, China does not have the opportunity to come into contact with the latest lithography machines, and naturally it does not have the ability to replicate this technology.

So, it seems normal that Qiu Mai doesn’t know, or that no one in the country knows?

But I really know it!

You can know it even without using the system!

Because its principle is really not as complicated as Qiu Mai expected.

Thinking of this, Chen Nian continued without waiting for Qiu Mai's answer:

"The principle of off-axis alignment technology is actually not complicated. In the final analysis, it uses light of a fixed wavelength for diffraction illumination, then marks the reference grating, and then uses Moore East text to calibrate. When the silicon wafer is aligned with the grating

After that, the alignment is basically complete."

"The most difficult thing in this process is not the marking, but maintaining the stability of the system and the specific operation methods."

Listening to Chen Nian's words, Qiu Mai's expression gradually became serious.

She frowned and silently deduced the technical operation that Chen Nian said in her mind, but before she could finish the deduction, Chen Nian suddenly stopped.

"What's wrong? Why don't you continue?"

Qiu Mai asked doubtfully.

"Um, I don't know about it later, I just saw it from a magazine by chance."

"Oh, like this."

"There seems to be nothing wrong with your method, and the principle is not that complicated. Just like you said, the difficulty of this technology is not the principle, but how to implement it."

"However, having a theory is better than having no theory at all. Maybe we will be able to realize this technology in a while."

Qiu Mai's expression was a little regretful, but Chen Nian was secretly grateful.

Hey, luckily I kept it!

He originally thought that this was a very simple technology that did not involve confidentiality requirements at all.

But unexpectedly, before I even finished speaking, the system jumped out first!

【TSI+Athena Alignment System】

[Analyzing source point requirements: 3.6]

[Analyzing source point requirements: 3.2]

[Analyzing source point requirements: 2.1]

As the demand for analyzing source points continues to decrease, the number of source points held by oneself continues to increase.

When the demand for analyzing source points dropped to 1.5 points, the number of source points he received directly increased by 0.7 points.

Only then did Chen Nian remember that for the current world, this thing is an increase in knowledge!

Therefore, we can't tell it yet, at least not to Qiu Mai and Li Xiang who are not in the confidentiality sequence.

After you go back, find some time to write it down and give it to the experts at the Institute of Optoelectronics for study.

But having said that, with the addition of 0.7 source points, the consumption of the digital array radar is instantly made up.

He didn't hesitate and started the analysis directly.

After a period of intense dizziness, the technical obstacles of digital array radar were completely eliminated!

Then, he raised his head and looked at Qiu Mai in front of him, thinking to himself:

Does this girl have some koi attributes?

Every time I see her, I get something unexpected. Although she didn't bring it, she was the one who started it both times.

If something like this happens again for the third time, think of a way to support her in the group. It would also be good to be a mascot.
