North America, California.

The video was finally played, but the office was still silent. Only Denapp and Jerryn could hear heavy breathing sounds. The sound was like two desperate beasts, forced into a dead corner.

"How is this possible!"

After a few minutes of silence, Denapp finally stood up. He waved his arm hard and then pressed the replay button. It seemed that he couldn't believe what he had just seen and thought it was not true.

Jerryen grabbed his friend's arm and said in a deep voice: "Forget it, don't look at it anymore. We are all scientists. Everything Luo Jia introduced is impeccable. We are very clear about this. It is just that humans have a habitual fluke mentality that makes us unacceptable for a while."

Plop ~

Denapp seemed to be lost, sat back on the sofa, his eyes were dull, his face turned pale, and he kept muttering the same sentence, "Impossible...This is impossible..."

Jerryn shook his head. He understood his old friend's pain very much. Ultrasonic motors are the treasures of the Jet Propulsion Laboratory. They have been studying for decades, but they lost a lot in the confrontation with Star Technology. This has hit Denapp too hard.

Jarien stood up, frowned and walked to the window, letting the sunlight fall on him. But for some reason, the bright sun in California no longer made him feel warm. The office was full of chills, as if someone secretly turned on the air conditioner, which made Jarien get goosebumps.

Time and again, Xingchen Technology broke the confidence of the West and did what the great powers could not do. This situation was really bad. Seeing the group of barbarians from China unscrupulously around the world, the Western technology community was unable to resist.

Jerryn comforted Denap and said: "Cheer my old friend, you are the famous jet propulsion laboratory. Ultrasonic motors are just one of the countless black technologies you have. Even if you are overtaken by Xingchen Technology, it is nothing great."

"Everyone says that ultrasonic motors belong to the space age, but what can they do with ultrasonic motors? Can they land on Mars? Can they explore the distant Pluto and Ebola belts?"

"cannot!"

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

"Don't forget my friend, we landed on the moon as early as 1969! At that time, China had not officially begun their industrialization. This was not a decades gap, but a hundreds of years gap!"

"It's still early for Chinese people to challenge us!"

After hearing Dr. Jerryen's words, Denapp not only was not inspired, but instead gave a bitter smile.

"Maybe what you said makes sense, but don't forget that Star Technology has just been established for four years!" Denapp twitched all over and shouted in pain.

......

Shanghai Capital, Pudong District, SMIC.

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

My temples were already gray, and the wrinkles on my forehead were like carved by a knife. At this age, I should have seen through everything in this world.

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

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

"What is awesome? That's it!"

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

"We are blessed now. Ultrasonic motors should be very helpful in solving our difficult machine accuracy problems, right?"

"You can't be wrong. The R&D department is already crazy and is crowded in the laboratory."

"Wait for me after get off work."

"What are you doing?"

"I'll treat you, have two drinks tonight!"

As the company's boss, Tang Boyun looked at the messy office and couldn't help but look straight and wanted to scold him, but for some reason, his nose was a little sore just now.

He thought of the criticisms the company has been carrying over the years. As a semiconductor company supported by the country at all costs, SMIC has spent a lot of money on the country.

However, when TSMC and Samsung sprinted 5 nanometers or even lower the process, SMIC was still spinning at 22 nanometers.

For this reason, the masses have repeatedly hit the backbone of SMIC, and SMIC employees also feel very wronged. The pursuit of top technology is not a cabbage, it is really not that easy.

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

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

Then there was an ultrasonic motor. Miracles were added together again and again, and finally everyone could not help but start an explosive celebration.

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

They are conducting research on the machine and want to know how much impact it will have on the yield rate of the production line if it is replaced with an ultrasonic motor.

People who don’t know the experts may not know at all that the yield rate problem in the semiconductor manufacturing industry has always been very serious.

Yield rate is not only a problem for SMIC, but also plagued TSMC, Grocery, Samsung, and even the arrogant Intel.

When TSMC launched the 7-nanometer technology, their old rival Samsung had been holding it in for several months and finally only came up with an 8-nanometer technology.

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

This number is strange and disgusting.

No more or less, only one nanometer lower than TSMC? What is the story behind it?

The real reason is the yield rate. Samsung can of course be made of 7 nanometers, but out of ten thousand products, 6,000 of them will be scrapped because they are not qualified. Although Samsung has a great family, it does not dare to play like this.

So, they bit the bullet and launched the 8-nanometer technology. Although they only missed one nanometer, the yield rate could reach 60%. Samsung would not lose its pants when operating this production line.

Some people may not understand, the yield rate of a nanometer gap is so much different?

Yes, it's so much different. Intel is considered the global overlord, right? But you may not know that many i5cpus are actually i7s that do not meet the standards. After blocking some cores and caches, they will be sold to you as i5.

This is the reality of the semiconductor industry. The process has reached the level of several nanometers, and further development is about to produce electron migration. Simply put, it has entered the limit of the current technology level.

Unless new technology emerges, the yield rate will never be too high, reaching 50%, and TSMC will thank God for the ancestors.

As for Xingchen Technology's ultrasonic motor, although it is just a motor, it seems to have nothing to do with the semiconductor industry.

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

So when this kind of motor came out, it was not the one who made motors, but a group of semiconductors!

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