Daguo Science and Technology started from the copycat system

After all, the current era is not the 2023 of the previous life. At that time, after twenty years of development, it was very easy for the purity of the wafer to reach nine nines.

In this era, the purity of wafers can reach 7 nines, which is considered first-class, and it can achieve 8 nines, which is the first-class among the first-class, and can achieve 9 nines, which is the world's top purity.

After all, the process technology in the current era is not too advanced, and the most advanced process technology is only 90 nanometers, and the requirements for the purity of wafers are not as abnormal as in the previous life.

It can't meet the abnormal purity requirements of 14 nine levels required to produce chips below 14 nanometers in the previous life.

Based on the current 130nm process technology of Sugon Technology, the purity of 7 nines is actually enough. If it can reach 8 nines, it will be the best, which can significantly improve the yield rate.

In fact, nine 9-level wafers are completely unnecessary, because nine 9-level wafers are enough to produce 90nm-level chips, and the performance of 130nm is somewhat exceeded.

After all, if you want to upgrade to a higher purity, raw materials and various production costs will definitely increase a little bit, which will eventually lead to an increase in the price of wafers with the increase in purity.

Therefore, the purity of the wafer is not the higher the better under the factor of price and cost, but the more suitable is the best.

With the current 130nm process technology, the level of 7 9s and 8 9s is the most suitable.

"Is the purity of nine nines high?"

Ms. Meng Yazhou at the side still couldn't help but asked Yu Chengxi curiously.

Seeing this, Yu Chengxi explained to the two people at the scene what it means for the purity of the wafer to reach 9 nines? Then naturally there were two exclamations.

After that, the two looked at Lin Chen with different eyes. Although Meng Yazhou admired Lin Chen's improvement of purity from three 9s to seven 9s in just over a month.

But I also feel that Lin Chen is a bit exaggerated. After all, if you really want to achieve the level of 9 nines, it will not be easy at first glance. This is already the top level of purity in the world.

It can be said that with the 9 9-level wafer purity, it can be regarded as the world's most popular wafer production plant.

At that time, even if they don't produce the chips themselves, and sell the 8-inch wafers with a purity of 9 to 9 to other chip production factories, they will definitely rush to get them!

Ren Zhengfei at the side also believed that Lin Chen could do it after being surprised. After all, since he knew Lin Chen's character, Lin Chen probably wouldn't joke about it.

Seeing this, Lin Chen didn't explain anything to the unbelieving Meng Yazhou.

Instead, after inspecting the fab, he inspected other chip production workshops, and finally inspected the most critical three chip production workshops.

The three chip production workshops are the 350-nanometer chip production workshop, the 180-nanometer chip production workshop and the final 130-nanometer chip production workshop.

Ren Zhengfei, Meng Yazhou, and Yu Chengxi heard that the 350nm and 180nm process technologies have made considerable progress in the past ten days.

When the yield rate of the 350nm and 180nm process technology has officially reached 99%, the three of them were naturally very surprised, and then looked at Lin Chen as if they were looking at an alien.

Lin Chen also smiled at this and took them to inspect the 130nm chip production workshop. When the three of them heard that Lin Chen had been there for more than ten days.

When the yield rate of the 130nm process technology was raised to 83% again, Ren Zhengfei, Meng Yazhou, and Yu Chengxi were almost numb from shock.

No small breakthroughs have been made in more than ten days. This Lin Chen is simply an unscientific and inhuman existence. No wonder Suguang Technology can grow to its current level in a year.

Lin Chen just smiled at this, and did not appear arrogant.

Because in the virtual laboratory, the yield rate of 130nm has reached 99.3%.

It can be said that there is only one step away from 99.9%. As for the next step to increase to 99.99%, Lin Chen is quite confident.

It took half a day and two or three hours for Lin Chen, Ren Zhengfei, Meng Yazhou, and Yu Chengxi to inspect the entire chip factory.

After that, the group of people did not wander around the factory, but walked out of the factory and drove to a big local hotel in Tianjin.

After all, he was Lin Chen's idol in his previous life. Lin Chen would not treat a few guests badly, and the two sides still have cooperation to discuss, so he should be generous and treat them to food and drink.

"It was a worthwhile trip this time, I finally understand why Mr. Lin's chip factory can produce such good chips?

With Mr. Lin in charge of the chip factory, it's no wonder that the chip's physique is not so good. "

At this time, Hua Wei's head, Ren Zhengfei, said with emotion.

Although in the two or three hours he was just looking at the flowers and didn't really understand the professional knowledge, Lin Chen was relatively calm when explaining the data.

In the end, it was only through Yu Chengxi's surprised expression that he knew that the data explained by Lin Chen was unusual, but even after these two or three hours passed.

He also knows that Suguang Technology is indeed very powerful, and finally Suguang Technology has mastered the unique chip physique improvement technology, which is even more powerful.

Of course, in this industry, Sugon Technology's chip physique improvement technology was not specially displayed, and Lin Chen did not introduce this aspect.

Ren Zhengfei expressed his understanding of this. After all, how could the core technology of really good things be seen by outsiders.

What if someone memorizes the key details, and then develops and cracks Suguang Technology's chip physique improvement technology?

If Lin Chen knew about this, he would just smile and copy it casually, because there is no physical improvement technique at all.

That's only due to the 15% increase in the quality of the BUFF in the king of the cottage system. If they can copy it, Lin Chen will laugh!

"Physical?"

Hearing Ren Zhengfei's emotion, Lin Chen finally understood why Huawei Technology came to Sugon Technology to manufacture chips.

Obviously, Huawei Technology has discovered the little secret that the chips produced by Suguang Technology are average and super godly.

Lin Chen expressed his understanding after being slightly surprised. After all, it is impossible for this matter to remain undiscovered.

At this time, Ren Zhengfei also smiled when he heard Lin Chen's murmur:

"Yes, the Phoenix S1 mobile phone chip produced by your company can reach the level of excellent in every physique.

I am afraid that only a few of the 10,000 chips in other chip factories can reach your super physique. I have to say that the chips produced by Suguang Technology are indeed excellent.

With such a super chip physique, I am afraid that even if it is supplied to the military industry, it is completely qualified. After all, the military industry requires absolutely stable chips. "

"Haha, where is it, how can other military industries like us."

Lin Chen smiled and said modestly.
