Shenhao started after the college entrance examination

Opposite Fudan University, Ah Xing Coffee Shop.

An Liang found"The Universe in a Nutshell" according to Chen Xiaoxi's instructions. He found a place in the corner, then opened the book and started reading.

In fact,"The Universe in a Nutshell" is a bit difficult and obscure for An Liang, but it does not prevent An Liang from enjoying reading this book.

An Liang was quietly reading books in Ah Xing Coffee Shop. Almost half an hour later, An Liang's cell phone rang with an incoming call, and the caller ID showed Han Zheng Long.

Han Zhenglong is the pseudonym of Cui Zhenghao. He is a manager of Dark Core Technology Company and is mainly responsible for production management, process control, and process improvement.

Han Zhenglong was once a technical elite of Sansang Group, but due to a conflict with a senior manager of Sansang Group, coupled with the causal relationship of the winner system in life, he eventually became an executive of Dark Core Technology Company.

An Liang put on his Bluetooth headset to answer the call. He first asked in Korean,"What's the matter?"

Hearing An Liang speak Korean, Han Zhenglong was slightly stunned. He was proficient in Xia Mandarin, and addedHe has been living in Xia Country for the past year, surrounded by Xia Guoyu environment. He has long been accustomed to using Xia Guoyu, but now he suddenly hears Korean, which makes Han Zhenglong a little uncomfortable.

Han Zhenglong still responded in Xia Mandarin,"Mr. An, we have good news to report to you."

An Liang switched the language and asked in Xia Mandarin,"What good news?"

"There is good news about the improvement in the yield rate of the 7nm node process. Han Zhenglong explained.

In view of the Bald Eagle blockade restrictions, Dark Core Technology was unable to obtain the most advanced EUV extreme ultraviolet lithography machines, and only obtained DUV deep ultraviolet lithography machines through some special channels.

DUV deep ultraviolet lithography machines are mainly It produces chips with a 14-nanometer process. Although it can also produce chips with a 7-nanometer process after technological improvements, due to inherent technical limitations, its yield rate has not been high when producing chips with a 7-nanometer process. Take another chip manufacturer Taiji Electric For example, Taiji Electronics has acquired a large number of EUV extreme ultraviolet lithography machines. When it produces 7-nanometer process chips, its yield rate is as high as 92%.

More importantly, Taiji Electronics is no longer prepared to continue to work on the 7-nanometer node. Based on the excellent performance of EUV extreme ultraviolet lithography machines, Taichi has now entered the 5-nanometer process technology and further increased the yield rate to 95%.

DUV deep ultraviolet lithography machines simply cannot break through the 7-nanometer process limit, and dark core technology Naturally, it cannot enter the 5nm process field. Even in the 7nm node process, the yield rate is only 67%.

This yield rate is very bad. If the dark core technology wants to openly compete with Taichi, I am afraid it will be beaten by Taichi. There is no way to fight back.

Fortunately, the dark core technology does not need to compete with Taiji Electric. At present, the dark core technology only needs to serve the Dream Future Graphene Technology Group.

Before, Anliang retained the memory of Li Xiyan’s old street, the winner system of life. It will prompt that there is a corresponding reward, and the reward should be received now.

"How much has the yield rate increased?"An Liang asked

"After our process improvements, the current yield rate of the 7-nanometer process has increased from 67% to 85%, an increase of 18%.%"Description of Hanzhenglong

"I am confident that the yield rate will be further improved in the future. I am confident that the yield rate will be increased to over 95%!" Han Zhenglong added.

If the yield rate of dark core technology in the 7nm node process can really reach more than 95%, it will definitely be good news for the Dream Future Graphene Technology Group.

Even if the DUV deep ultraviolet lithography machine cannot achieve Advanced processes below 7 nanometers, but as long as the yield rate of the 7 nanometer node process is high enough, it can also meet the needs of the Dream Future Graphene Technology Group, thereby avoiding being blocked by the Bald Eagle.

"Good news indeed! An Liang replied affirmatively,"Have you conducted tape-out testing?""

"certainly. Hanzhenglong responded,"We have passed the tape-out test and conducted three tape-out tests. The yield rate of the 7-nanometer node process has indeed reached 85%. The highest yield rate was as high as 87%, and the lowest was 85.2%"

"very good!"An Liang praised

"I will record your success and give your team a bonus of 100 million, and I will give you an individual bonus of 10 million. An Liang added.

Han Zhenglong quickly responded with thanks,"Thank you, Mr. An." An

Liang said jokingly,"The bonus has been given to you. You must remember to declare taxes and be a legal tax-paying citizen.""

"Understand, I won't forget."Hanzhenglong responded quickly.

After the two parties ended the exchange, An Liang immediately sent a message to Zhao Wanxi

‘An Liang: Wanxi, have you returned to school?’

‘Zhao Wanxi: I didn’t go to school. What’s wrong?’

‘An Liang: There is good news from Dark Core Technology’

‘Zhao Wanxi: Has the manufacturing process broken through the physical limits?’

‘An Liang:...’

‘An Liang: What sweet dream are you dreaming about? '

Process technology breaks through physical limits?

Take a shower and go to sleep!

Nothing in the dream?

In my dream, I can even rub a 1nm process chip by hand!
