North America, California.

The video was finally over, but the office was still silent, except for the heavy gasps of Denapp and Jerryne, who were driven into a corner like two desperate beasts.

"How is this possible!"

After a few minutes of silence, Denapp finally stood up, waved his arms as hard as he could, and then pressed the replay button, as if he couldn't believe what he had just seen, thinking it wasn't real.

Jerry took his friend's arm and said in a deep voice: "Forget it, don't look any further, we are all scientists, everything Luo Jia introduced is impeccable, we know this very well, it's just the usual luck psychology of human beings, which makes us unacceptable for a while." ”

Puff~

Denapp sat back on the couch with a blank slate, his eyes glazed over, his face pale, and he kept repeating the same sentence, "Impossible... It can't be..."

Jerry shook his head, he understood the pain of his old friend very well, the ultrasonic motor is the treasure of the jet propulsion laboratory, and he has been studying it for decades, but he lost a mess in the confrontation with Xingchen Technology, which is too big a blow to Denapp.

Jerion stood up, frowned and walked to the window, letting the sun fall on him, but for some reason, the California sun no longer made him feel warm, and the office was filled with a chill, as if someone had secretly turned on the air conditioner, which gave Jerion goosebumps.

Time and time again, Xingchen Technology has shattered the confidence of the West and done what the great powers could not do, this situation is really terrible, watching the group of barbarians from China run unscrupulous all over the world, but the Western technology community is powerless to resist.

Jerry comforted Denapp and said, "Cheer up, my old friend, you are a famous jet propulsion laboratory, and the ultrasonic motor is just one of the countless black technologies you have mastered, even if it is surpassed by Xingchen Technology, it is not a big deal." ”

"It is said that ultrasonic motors belong to the space age, but what can they do with ultrasonic motors? Can it land on Mars? Can you explore the distant Pluto and Ebola belts? ”

"Can't!"

"Technology is a complete system, composed of thousands of technologies, an ultrasonic motor is nothing, want to challenge us, unless they can fill all the technological gaps!"

"Don't forget my friend, back in 1969 we landed on the moon! And at that time, China had not officially started their industrialization, and it was not a gap of decades, but a gap of hundreds of years! ”

"If you want to challenge us, the Chinese people are still very early!"

Instead of being encouraged, Denapp let out a wry smile when he listened to Dr. Jayryne's words.

"Maybe what you say makes sense, but don't forget, Xingchen Technology has only been established for four years!" Denapp convulsed and cried out in pain.

......

Shanghai, Pudong District, SMIC.

Tang Boyun wiped away his tears, washed his face with cold water, and looked at himself in the mirror.

The temples are already gray, and the wrinkles on the forehead are like carving knives, and at this age, you should have seen through everything in this world.

It can be learned that after Xingchen Technology's ultrasonic motor surpasses the incomparably powerful jet propulsion laboratory in terms of technical indicators, Mr. Tang still couldn't help but shed tears.

He calmed down his excitement, walked out of the bathroom, and saw that the company, which should have been serious, had turned into a sea of joy, and everyone was talking excitedly.

"What do you call a cow fork? That's it! ”

"First get the industrial software, and then use the ultrasonic motor, Xingchen Technology is simply using its own strength to pull the Chinese science and technology community forward!"

"Now we are blessed, the ultrasonic motor should be very helpful to solve our current thorny machine accuracy problem, right?"

"Can't be wrong, the R&D department is already crazy, and they are all crowded in the laboratory."

"Wait for me after work."

"What for?"

"I'm in for a treat, have a good drink tonight!"

As the CEO of the company, Tang Boyun looked at the messy office, couldn't help but straighten his face, and wanted to reprimand, but for some reason just opened his mouth, his nose was a little sour.

He thought of the scolding that the company has borne over the years, as a semiconductor company supported by the state at any cost, SMIC has spent a lot of money on the state.

However, when TSMC and Samsung are sprinting to 5nm or even lower, SMIC is still spinning at 22nm.

For this reason, the masses have poked SMIC's backbone, and SMIC's employees also feel very aggrieved, and the pursuit of top technology is not a cabbage, it is really not so easy.

"Forget it, let's make everyone happy." Tang Boyun thought to himself.

Not long ago, Xingchen Technology's industrial software allowed SMIC's old customers Huawei, ZTE, and UNISOC to get rid of the embarrassing situation of being stuck by the big powers at the software level, and the company was already very happy at that time.

Immediately followed by the ultrasonic motor, the miracles were superimposed again and again, and finally everyone couldn't help it anymore and began to celebrate explosively.

Tang Boyun ignored the noisy office, let the young people make trouble, turned around and came to the laboratory, changed into dustproof clothing, walked in, and met the company's main R&D forces.

They are studying the machine and want to know how much it will affect the yield of the production line if the fully automatic machine is replaced by an ultrasonic motor drive.

People who don't know the inside may not know that the yield problem of the semiconductor manufacturing industry has always been very serious.

Yield is not only a problem for SMIC, but also for TSMC, GLOBALFOUNDRIES, Samsung, and even Intel.

When TSMC launched 7nm technology, their old rival Samsung held back for several months, and finally only came up with 8nm technology.

The production lines are exactly the same, why is Samsung's process one nanometer lower than TSMC?

It's a strange number, and it's disgusting.

No more, no less, only one nanometer lower than TSMC? What's the story behind it?

The real reason lies in the yield rate, of course, Samsung can be produced with 7 nanometers, but among the 10,000 products, 6,000 pieces will be scrapped because they are unqualified.

So, they took the plunge and launched 8 nanometer technology, don't look at the fact that the production is only one nanometer off, but the yield rate can reach 60 percent, and Samsung will not lose pants when it runs this production line.

Some people may not understand that with a nanometer gap, the yield rate is so much worse?

Yes, it's just so much worse, Intel is the global hegemon, right? But you may not know that many I5CPUs are actually substandard I7s, and after shielding some cores and caches, they are sold to you as I5.

This is the reality of the semiconductor industry, the process has reached the level of a few nanometers, and then the development is about to produce electron migration, in short, it has entered the limit of the current level of science and technology.

Unless a new technology is born, the yield rate will never be too high, and it can reach 50 percent, and TSMC will thank God for it.

The ultrasonic motor of Xingchen Technology, don't look at it as just a motor, it seems to have nothing to do with the semiconductor industry.

However, this kind of motor with nano-level precision can improve the accuracy of machine operation, thereby improving the yield rate and solving the big trouble of semiconductor manufacturing!

So when this kind of motor came out, the crazy ones were not those who made motors, but a group of semiconductors!

"How?" Tang Boyun asked with concern, "If we replace the ultrasonic motor, how much accuracy can our machine improve?" ”
