After all, the current era is not 2023 in the previous life. At that time, after twenty years of development, it was easy to achieve 9 9 levels of purity of wafers.
In this era, a wafer with a purity level of 7 9s is considered first-class, a wafer purity level of 8 9s is even better than the best of the best, and a wafer purity level of 9 9s is the world's top purity level.
After all, the current process technology is not too advanced. The most advanced process technology is only 90 nanometers, and the purity requirements for wafers are not as abnormal as in previous generations.
It cannot meet the abnormal purity requirements of 14 9-levels required in previous generations to produce chips below 14 nanometers.
Based on Sugon Technology's current 130nm process technology, the purity of 7 9s is actually enough. It would be best if it could reach 8 9s, which can significantly improve the yield rate.
In fact, nine Level 9 wafers are completely unnecessary, because nine Level 9 wafers are enough to produce 90-nanometer chips, and the performance is exceeded when used at 130 nanometers.
After all, if you want to upgrade to a higher purity, raw materials and various production costs will definitely increase slightly, which will eventually cause the price of wafers to increase as the purity increases.
Therefore, the purity of wafers is not the higher the better due to price and cost factors, but the more suitable is the best.
Based on the current 130nm process technology, the levels of 7 9s and 8 9s are the most suitable.
"Are the nine nines very pure?"
Ms. Meng Yazhou on the side couldn't help but asked Yu Chengxi out of curiosity.
Seeing this, Yu Chengxi explained to the two people present what it meant that the purity of the wafer reached nine nines. Then naturally there were two exclamations.
After that, the two people looked at Lin Chen with different eyes. Although Meng Yazhou admired Lin Chen for raising the purity level from three 9s to 7 9s in just over a month.
But I also think Lin Chen is exaggerating a bit. After all, it is not easy to achieve the level of 9 9s. This is already the top level of purity in the world.
It can be said that with 99 levels of wafer purity, it has truly entered the world's most popular wafer production plant.
Even if you don't produce chips yourself and sell 8-inch wafers with a purity of 9.9 to other chip production factories, they will definitely rush to get them!
Ren Zhengfei on the side was surprised and believed that Lin Chen could do it. After all, he knew Lin Chen's character, so Lin Chen would not make a joke in this regard.
Seeing this, facing the unbelieving Meng Yazhou, Lin Chen did not explain anything.
Instead, after inspecting the wafer factory, they inspected other chip production workshops, and finally inspected the three most critical chip production line 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.
When Ren Zhengfei, Meng Yazhou, and Yu Chengxi heard that the 350 nanometer and 180 nanometer process technologies had made great progress in the past ten days.
When the yield rates of the 350 nanometer and 180 nanometer processes had officially reached 99%, the three of them were naturally shocked, and then looked at Lin Chen as if they were looking at aliens.
Lin Chen also smiled at this and then took them to inspect the 130 nanometer 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 130-nanometer process technology was once again increased to 83%, Ren Zhengfei, Meng Yazhou, and Yu Chengxi were almost numb with shock.
In more than ten days, they all made great breakthroughs. This Lin Chen is simply an unscientific and inhuman existence. No wonder Sugon Technology can grow to its current level in one year.
Lin Chen just smiled at this and did not appear arrogant.
Because in the virtual laboratory, the yield rate of 130 nanometers has reached 99.3%.
It can be said that it is only one step away from 99.9%. As for the next step to improve to 99.99%, Lin Chen is quite confident.
It took most of the day and two or three hours for Lin Chen, Ren Zhengfei, Meng Yazhou, and Yu Chengxi to finally inspect the entire chip factory.
Then the group did not wander around the factory, but walked directly out of the factory and drove to a large local hotel in Tianjin.
After all, he was Lin Chen's idol in his previous life. Lin Chen would not treat a few visitors badly, and the two parties still had cooperation to discuss, so he should be generous and treat them to food and drinks.
"This trip is really worthwhile. 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 that good. "
At this time, Ren Zhengfei, the head of Huawei, said with emotion.
Although during these two or three hours, he only glanced at the facts and did not actually 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 Lin Chen explained was unusual, but even after two or three hours.
He also knows that Sugon Technology is indeed very powerful. Finally, coupled with Sugon Technology's unique chip physique improvement technology, this is even more powerful.
Of course, in this industry, Sugon Technology's chip physique improvement technology was not specifically displayed, and Lin Chen did not introduce this aspect.
Ren Zhengfei expressed his understanding of this. After all, how could the core technology of truly good things be seen by outsiders?
What if someone remembers the key details and then develops and cracks Sugon Technology’s chip physique-improving technology?
If Lin Chen knew about this, he would just smile and say that he could just copy it, because there is no physical improvement technology at all.
That's just the 15% increase in the BUFF quality of the King of Copycat system. If they could copy it, Lin Chen would laugh!
"Physique?"
Hearing Ren Zhengfei's emotion, Lin Chen finally understood why Huawei Technology came to Sugon Technology to manufacture chips.
Obviously, Huawei Technology discovered the little secret of the chips produced by Sugon Technology having average physical fitness.
Lin Chen was slightly surprised by this and then expressed his understanding. After all, it was impossible for this matter to remain undiscovered forever.
At this time, Ren Zhengfei heard Lin Chen's murmur and said with a smile:
"Yes, the Phoenix S1 mobile phone chip produced by your company can reach the highest level of excellence in every aspect.
I'm afraid that only a few of the 10,000 chips in other chip factories can reach your level of super strength. I have to say that the chips produced by Sugon Technology are indeed excellent.
With such a super chip physique, I am afraid that even if it is supplied to the military industry, it will be fully qualified. After all, the military industry requires absolute stability for chips. "
"Haha, no matter where, the military industry doesn't care about us."
Lin Chen smiled and said modestly.
