Chapter 1450: Trap

"It's the data, not our calculations!!" Boss Jia licked his lips, an idea in his mind became clearer and clearer, and finally asked directly, "Teacher, where did the basic data we use to calculate come from?" ”

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

"No, some of the data is not measured at all, I remember that some of the data I was responsible for checking did not seem to be the result of the measurement!" Boss Jia squinted his eyes and said.

"Well, here's the data we pulled straight from the ASML machine!" Ni Guangnan said with some embarrassment: "In order to save time, I directly pulled the data from ASML's 70nm machine!" ”

"However, I can assure you that this part of the data is common for both dry and immersion and has no effect. Moreover, these data cannot be measured by measurement at all, but need to be accumulated by countless experiments! ”

"For example, the polarization angle of the engraving cannot be measured at all, and it can only be measured from 44.0000001 degrees to 45.999999999 degrees, and the experimental measurement can be carried out every 0.00000001 degrees to find out the best polarization angle."

"If we rely entirely on experiments to find out, then we have to carry out 20 million calculation experiments, and the time to calculate a polarization angle alone is more than three years, where do we have so much time!"

"The polarization angle is the same for both dry and immersion methods, and it doesn't have any effect. So I just used the polarization angle data from ASML! Anyway, it's all at the 70nm level, and the data is the same, so we don't need to spend a lot of time experimenting, because the final results are still the same as ASML's, which is a waste! ”

Ni Guangnan explained his behavior, although copying the data sounds a bit shameless, but it is actually very necessary.

Because a lot of data cannot be calculated or measured, it must go through tens of thousands or even tens of millions of experiments, and it is better to copy and paste directly from existing items.

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

Assuming that the story is completely true, Edison finally found bamboo silk after 13 months of experimentation and more than 6,000 kinds of materials in order to find the most suitable material for making equal silk.

And it is not an ordinary bamboo death, but it must be scorched through a high-temperature closed furnace, and then processed to obtain carbonized bamboo silk before it can be loaded into the bulb.

It took so much effort for Edison to find the material, and the rear wheel only needed to buy an incandescent bulb, and then take out the filament inside, reverse study and analysis, and in less than two days, he knew what the best material was.

Ni Guangnan did the same thing, 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 in it.

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

This method itself is also recognized by Boss Jia, otherwise why would Boss Jia go to great lengths to buy two of the most advanced 70nm lithography machines, not to give Ni Guangnan reverse research and seize the data inside.

This is something that both Boss Jia and Ni Guangnan have acquiesced to, and Ni Guangnan doesn't know what Boss Jia is doing when he mentions this again.

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

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

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

"Oh, isn't this Liu Nian's idea for that bastard boy? I heard that those Western scholars are still being tormented miserably, and they are still desperately researching germanium compounds! You guys are so bad! Ni Guangnan said with a smile.

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

"What, you're saying that the data we got from ASML's machine is fake!!" Ni Guangnan stood up abruptly and looked at Jia Yapeng in disbelief.

"It's not fake, it's just that compared with the real data, there is a little bit of a loss, a slight deviation!" Boss Jia shook his head, "After all, if it's too bad, it's impossible to fool us." ”

"It's impossible, if ASML's machine data is fake, then why can their lithography machine make a perfect chip!" Ni Guangnan asked puzzled.

"It's simple, or it's data fraud, but it's 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 this last degree is the really 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 fake, but in the backing plate, it increases the gap of 110,000 degrees, and it cannot be detected without high-precision instruments, but who will test a lithography machine like this?" Boss Jia said, "You don't need too much fake data like this, just four or five, and you can completely destroy all the attempts of the imitators." ”

"But in this case, how can we explain that it is not wrong for us to do experiments on ASML machines?" Ni Guangnan still asked with some disbelief.

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

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

"When you say that, I seem to remember...... Ni Guangnan's expression stiffened, "The chips produced by the 120nm lithography machine we produce always have some wrong angles, and at the same time, there are more broken transistors than Western products, and the overall quality of the product is not as good as that of Western products anyway." ”

"It's just that I thought it was a problem with many details in the manufacturing process, so it's normal to be inferior to the West, I didn't think much about it, I didn't expect that the data used to control production and manufacturing was wrong, and the 120nm equipment also used ASML70nm data!" Having said this, Ni Guangnan's expression was already miserable.

"That's right, teacher, I suggest that all forces be mobilized immediately to review and recalculate the data using ASML, and at the same time, I will also send a program expert to check the underlying program code of ASML to see if I can find the secret hidden in it!"
