"The wrong data is the data, not our calculations!!" Boss Jia licked his lips, and an idea in his mind became clearer and clearer. Finally, he asked directly, "Teacher, where did the basic data we used to calculate come from?"

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

"No, some data are not measured at all. I remember that some of the data I was responsible for verifying did not seem to be the result of the calculation!" Boss Jia said with his eyes narrowed.

"Okay, this is the data we directly cut off from the ASML machine!" Ni Guangnan said embarrassedly. "In order to save time, I directly cut off the data from the ASML 70nm machine!"

"But I promise that this part of the data is universal for both dry and immersion and has no effect. Moreover, these data are not measured at all, but require countless experiments to accumulate!"

"For example, the problem of polarization angle of the printed mark cannot be measured at all. Only experimental calculations can be carried out every 0.00000001 degrees until 44.0000001 degrees to 45.999999999, and the best polarization angle can be found."

"If we rely entirely on experiments to find it, we have to conduct 20 million calculation experiments. The time for measuring a polarization angle is more than three years. Where can we get so much time!"

"The polarization angle is the same for both dry and immersion methods, and has no effect. So I directly used the polarization angle data of ASML! Anyway, they are at the 70nm level, and the data are the same. We don't need to spend a lot of time experimenting, because the final results of the experiment are still the same as those of ASML, which is too wasteful!"

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

Because many data cannot be obtained through calculation or measurement, it must be subject to tens of thousands or even tens of millions of experiments. It is better to copy and paste them directly from existing items.

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

I will never tell whether this story is true or false. Assuming that this story is completely true, Edison finally tried it for 13 months and more than 6,000 materials before finally finding bamboo silk.

And it is not an ordinary bamboo, but it must be burned through a high-temperature closed furnace and processed to obtain charred bamboo wire before it can be installed in the light bulb.

Edison spent so much effort to find the material. He only needed to buy an incandescent light bulb on the rear wheel, then took out the filament inside, and studied and analyzed it in reverse. In less than two days, he knew what the best material was.

What Ni Guangnan did is the same, because it took too much time and money to collect these experimental data, so he simply bought an ASML 70nm lithography machine and then directly obtained the data. It was so fast.

Although this method itself is very shameless, it is very effective. Otherwise, Boss Jia would have to wait at least more than three years before he could see the experiment in front of him.

This method itself is also recognized by Boss Jia. Otherwise, why did Boss Jia go through a lot of hardships to buy two most advanced 70nm lithography machines? It was not just to reverse research for Ni Guangnan to seize the data inside.

This is what Boss Jia and Ni Guangnan both agreed to. Ni Guangnan didn’t know what Boss Jia mentioned 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 didn't know.

"It's just to prevent others from discovering graphene, and then add some additional materials!" Boss Jia rubbed his temples.

"Oh, isn't this the idea of ​​that bastard Liu Nian? I heard that he is still trying hard to deal with those Western scholars. They are still working hard to study germanium compounds! You are so bad!" Ni Guangnan said with a smile.

"So, I was wondering, will ASML do the same thing to us?" Boss Jia said lightly.

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

"It's not fake, it's just that there's a little bit of deviation compared to the real data!" Boss Jia shook his head. "After all, if there's too much difference, it's impossible to deceive us."

"This is impossible. If the ASML machine data is fake, then why can their lithography machines make perfect chips!" Ni Guangnan asked in confusion.

"Simple, either the data is fake, but it is not fake in the actual manufacturing process. For example, the data it displays is 44.88667234 degrees, but in fact, when operating, 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 the database is the wrong degree."

"There is also that the program itself is not fake, but the gap is 110,000 degrees higher than the pad plate. It cannot be detected without high-precision instruments. But who would detect a lithography machine like this?" said Boss Jia. "There is no need for too much fake data like this. Just four or five can completely destroy all the attempts of imitators."

"But in this case, how can we explain it? It's not wrong to do experiments without ASML machines?" Ni Guangnan asked back with some disbelief.

"Teacher, except for this experiment, we have never tried these experiments at the 70nm level before. After all, we can only meet the conditions at the 120nm level at most and verify them according to 120nm."

"In this case, the accuracy is several levels lower, and 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."

"After you say this, I seem to remember..." Ni Guangnan's expression froze. "The chips produced by the 120nm lithography machine we produce always have some wrong angles. At the same time, there are more damaged transistors than Western products. The overall quality of the product is inferior to Western products in any case."

"But I thought this was a manufacturing process and there were many details, so it was not as normal as the West. I didn't think much about it. I didn't expect that the data used to control the production and manufacturing was wrong. The 120nm equipment also uses ASML70nm data!" At this point, Ni Guangnan's expression turned pale.
