“The data is wrong, not our calculations!!” Boss Jia licked his lips, an idea in his mind became clearer and clearer, and finally asked directly “Teacher, the basis for our calculations Where did the data come from?”

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

“No way, some data is not measured at all. I remember that in the data I am responsible for checking, there is a part of it, it seems that it is not the result of the calculation!” Boss Jia said with squinting eyes.

“Well, this is the data we picked directly from the ASML machine!” Ni Guangnan said somewhat sorry, “In order to save time, I picked the data directly from the ASML 70nm machine!”

“But I guarantee that this part of the data is common to both dry and immersion types and has no effect. And these data, simply cannot be measured by measurement, but need countless experiments to accumulate !”

“For example, the problem of the polarization angle of the marking, this can not be measured at all. It can only be measured from 44.0000001 degrees to 45.9999999 degrees, every 0.00000001 degrees, to find the best polarization angle.”

“If we rely solely on experiments to find out, we have to conduct 20 million calculation experiments. It takes more than three years to calculate a polarization angle. Why do we have so much time!”

“The polarization angle is the same for the two ways of dry and immersion, and has no effect. So I directly used the ASML polarization angle data! Anyway, they are all 70nm. , The data are all the same, we don’t need to spend a lot of time to experiment, because the final result of the experiment is still the same as ASML, which is too wasteful!”

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

Because a lot of data cannot be obtained by calculation or measurement, it has to go through tens of thousands or even tens of millions of experiments. It is better to copy and paste directly from the existing items.

For example, Edison made a light bulb, which is also one of the classic arguments for China’s composition.

Never tell this story true or false, assuming that this story is completely true, Edison, in order to find the most suitable material for making silk, finally tested more than 6000 materials for 13 months before finally finding The bamboo silk.

Moreover, it is not ordinary bamboo death, but it needs to be burnt in a high-temperature airtight furnace, and then processed to obtain carbonized bamboo silk before it can be installed in the bulb.

It took so much effort for Edison to find the material. The rear wheel only needs to buy an incandescent bulb, and then take out the filament inside. Reverse research and analysis. In less than two days, he knew the best What is the material?

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, and then directly obtain the data. , A quick one.

Although this method itself is very shameless, it is very effective, otherwise Boss Jia will have to wait at least three more years before he can see the experiment before him.

This method itself is also recognized by Boss Jia. Otherwise, why would Boss Jia spend all the suffering untold hardships and buy two state-of-the-art 70nm lithography machines? It’s not for Ni Guangnan’s reverse research and capture the inside data.

This is the default thing of both Boss Jia and Ni Guangnan. Ni Guangnan doesn’t know what Boss Jia is doing 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 is to prevent others from discovering graphene, and then add some additional materials!” Boss Jia rubbed his temples.

“Oh, isn’t this the idea of ​​Liu Nian’s little bastard? I heard that the Western Scholars are still tossing badly. They are still working hard on germanium compounds! You are too bad!” Ni Guangnan said with a smile.

“So, I’m thinking, will ASML do the same thing to us?” Boss Jia lightly saying.

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

“It’s not fake, it’s that compared with the real data, there is so much loss, a slight deviation!” Boss Jia shook his head, “After all, if the difference is too much, it is impossible to fool us.”

“This is impossible. If the ASML machine data is fake, then why can their lithography machine make perfect chips!” Ni Guangnan asked puzzledly.

“Simple, it is either data falsification, but no falsification in the actual manufacturing process. For example, the data it displays is 44.88667234 degrees, but in actual operation, the system will automatically increase the degree such as 0.00001, and this The final degree is the correct data, but what you see in the operation panel and database is the wrong degree.”

“There is also the fact that the program itself is not fraudulent, but there is an increase of 110,000 degrees in the backing board. It will not be detected without high-precision instruments. But who would test a lithography machine like this?” Boss Jia said, “This way fake data doesn’t need too much. As long as four or five, it can completely destroy all counterfeiters’ attempts.”

“But in this case, how do you explain it. It’s not wrong for us to experiment on a machine that is separated from ASML?” Ni Guangnan still asked in disbelief.

“Teacher, apart from this time experiment, these experiments have never been tested at the 70nm level before. After all, we can only achieve the conditions of the 120nm level before, and we will verify it according to 120nm.”

“In this case, the accuracy is several levels lower. As long as the difference in the data is not too much, there will not be a problem! But once the accuracy is high, it becomes a complete disaster.”

“When you said that, I seem to remember…” Ni Guangnan’s expression froze. “The 120nm lithography machine we produce always has some wrong angles on the chips, and the damaged transistors are also better than Western ones. There are more products, and the overall product quality is inferior to Western products anyway.”

“It’s just that I thought this was a problem with many details in the manufacturing process, so it’s not as normal as in the West. I didn’t think too much about it. The data used by didn’t expect to control production is wrong. The 120nm device The data used is also ASML70nm!” At this point, 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 a program expert to check the underlying program code of ASML to see if I can find it. The secret hidden in it!”
