Chapter 1350

"The wrong thing is the data, not our calculation!!" boss Jia licked his lips. An idea in his mind became clearer and clearer. Finally, he directly asked, "teacher, where did the basic data we used to calculate come from?"

"Of course we measured it ourselves!" Ni Guangnan subconsciously replied.

"No, some data are not measured at all. I remember that some of the data I am responsible for checking and calculating are not the calculation results!" boss Jia narrowed his eyes and said.

"Well, this is the data we picked directly from the ASML machine!" Ni Guangnan said with some embarrassment. "In order to save time, I picked the data directly from the ASML 70nm machine!"

"However, I guarantee that this part of data is common to both dry and immersion types and has no impact. Moreover, these data can not be measured at all, but need countless experiments to accumulate!"

"For example, the polarization angle of the engraving can't be measured at all. The best polarization angle can only be found by experimental calculation every 0.00000001 degrees from 44.0000001 degrees to 45.999999 degrees."

"If you rely entirely on experiments to find it, you have to carry out 20 million calculation experiments. It takes more than three years to calculate a polarization angle. How can we have so much time!"

"The polarizing angle is the same for both dry and immersion methods, without any impact. So I directly use the polarizing angle data of ASML! Anyway, it is 70nm level, and the data are the same. We don't need to spend a lot of time on the experiment, because the final experimental results are still the same as those of ASML, which is too wasteful!"

Ni Guangnan explained his behavior. Although copying the data sounds shameless, it is actually very necessary.

Because many data can not be obtained through calculation or measurement, it must go through tens of thousands or even tens of millions of experiments. It's better to copy and paste directly from existing items.

For example, Edison made a light bulb, which is also one of the classic arguments of Chinese composition.

Never say whether the story is true or false. Assuming that the story is completely true, Edison finally found bamboo silk after testing more than 6000 materials for 13 months in order to find the most suitable material for manufacturing such silk.

Moreover, it is not the death of ordinary bamboo, but burning and reprocessing in a high-temperature closed furnace to obtain carbonized bamboo wire, which can be installed in the bulb.

Edison spent so much effort to find the material. He only needed to buy an incandescent bulb, take out the filament inside, and conduct reverse research and analysis. He knew what the best material was in less than two days.

Ni Guangnan does the same thing, because it takes too much time and money to collect these experimental data, so just buy an ASML 70nm lithography machine directly, and then directly obtain the data. It's a quick force.

Although this method itself is very shameless, it is very effective. Otherwise, boss Jia will have to wait at least three more years to see the experiment in front of him.

This method is also recognized by boss Jia. Otherwise, why did boss Jia bother to buy two of the most advanced 70nm lithography machines? It's not to reverse study Ni Guangnan and capture the data inside.

This is the default of both boss Jia and Ni Guangnan. Ni Guangnan doesn't know why boss Jia mentioned it again.

"Teacher, do you remember what we did on the TF card?" boss Jia suddenly asked with a wry smile.

"What's the matter?" Ni Guangnan really doesn't know.

"Just to prevent others from discovering graphene and then adding some additional materials!" boss Jia rubbed his temple.

"Oh, isn't this the idea of that bastard Liu Nian? It's said that those western scholars are still struggling. They are still desperately studying germanium compounds! You're too bad!" Ni Guangnan smiled.

"So, I wonder if ASML has done the same thing to us?" boss Jia said faintly.

"What, you mean, the data we obtained from the ASML machine is false!!" Ni Guangnan suddenly stood up and looked at Jia Yapeng in disbelief.

"It's not fake, but there's a slight deviation from the real data!" boss Jia shook his head. "After all, if it's too bad, it's impossible to deceive us."

"It's impossible. If ASML's machine data is false, why can their lithography machine make perfect chips!" Ni Guangnan asked puzzled.

"Simple, or it is data fraud, but it is not fake in the actual manufacturing process. For example, the data displayed is 44.88667234 degrees, but in fact, during operation, the system will automatically increase the degree of about 0.00001, and the last degree is the real correct data, but what you see in the operation panel and database is the wrong degree Count. "

"There is no fraud in the program itself, but the gap of 110000 degrees is increased in the base plate. It can't be detected without high-precision instruments, but who will test a lithography machine like this?" boss Jia said. "There doesn't need too many fake data. As long as four or five, it can completely destroy all the attempts of counterfeiters."

"But in this case, how can we explain that it's not wrong for us to do experiments without ASML machines?" Ni Guangnan asked in disbelief.

"Teacher, apart from this experiment, these experiments have never been tested at the level of 70nm before. After all, we can only reach the condition of 120nm at most and verify according to 120nm."

"In this way, the accuracy is several levels lower. As long as the data difference is not too much, there will be no problem! But once the accuracy is high, it will become a complete disaster."

"When you say that, I seem to remember..." Ni Guangnan's expression was stiff. "The chips produced by our 120nm lithography machine always have some wrong angles. At the same time, there are more damaged transistors than Western products. The overall product quality is not like Western products anyway."

"But I thought it was a manufacturing process and there were many details, so it was not as normal as in the West. I didn't think much. I didn't expect that the data used to control production and manufacturing was wrong. 120nm equipment also used asml70nm data!" Ni Guangnan's expression was pale.

"That's right, teacher. I suggest that we immediately mobilize all forces to review and recalculate the data using ASML. At the same time, I will send program experts to check the underlying program code of ASML to see if we can find the secret hidden in it!"
