Chapter 183 The sword is not old and its sharpness remains unchanged

“5nm yield is 78%!?”

When he heard that the EUV photoresist developed by the School of Microelectronics of Jiangsu University had completed the 5-nanometer experiment in Shanghai, Kang Chi stood up excitedly.

The volume was raised and immediately attracted a lot of attention.

"Well, the yield rate of 78% is a bit low, so it is estimated that it is only 5nm at most. If used to achieve 3nm, the yield rate may not even be 50%."

"Teacher Wu, this is your fault." Kang Chi immediately said seriously, "We can't be too greedy. We can always become fat in one bite, right?"

"And the yield doesn't just depend on the photoresist. Other factors also have a great influence. If they use a small photoresist, the yield probably won't exceed 85%, right?"

"Well, their original yield rate was just 84%, and ours was actually 6% lower. If the debugging is done well, there is hope that it can reach more than 80%... But speaking of you, you are talking more and more like a big boss recently. .”

"Hey, stop talking. If I were really a big leader, why would I have to work in other companies?" Kang Chi sighed, "Can Senior Brother Wang graduate now?"

"Well, don't worry, I'll give him to you tomorrow."

Wu Lihong looked at Wang Haowen next to him with a smile, then covered the microphone and whispered,

"He also contributed a lot to this photoresist breakthrough. He is smart and hard-working. If he is willing to stay and teach in our institute and university, he might become a Yangtze River Academician in the future. To be honest, I really I’m a little reluctant to let it go to you…”

"Then you can offer them a million-dollar annual salary."

"..."

Wu Lihong opened his mouth, unable to refute.

Today is a money society. Don’t say that these young people are obsessed with money. They were anxious when their funds were cut before.

So Wu Lihong didn't say anything about Wang Haowen's choice to pursue profit.

Moreover, if you go to Kang Chi's side, your future achievements may be higher than if you follow him, especially since he is ready to take a back seat.

During this period, Wu Lihong had clearly felt that he was unable to keep up with the efficiency and intensity of the research team.

The only way I can hold on until now is with just one breath.

Now that photoresist has finally achieved a breakthrough, his tone has dissipated, and he no longer has the courage to take the lead.

In fact, a few months ago, he decided that once the photoresist problem was solved, he would step back and start focusing on talent training.

[The sword is not old, and its sharpness remains unchanged! ——Wu Lihong, my country’s chip academician, led the microelectronics research team of Jiangsu Province University and successfully developed the first domestic top-level EUV photoresist!

The breakthrough of this material marks that my country's independent chip manufacturing process will completely enter the 5nm era and be at the world's first-class level! 】

The next day, when Zhang Dayuan saw the Huaguo News published this news on a large page, the smell of sour vinegar emanated from his nostrils, and even his students hurriedly backed away.

"He was actually taken care of by this old guy!?"

Zhang Dayuan was happy for him, but at the same time felt how unfair God was!

They are an old man and a young man in the south, one of them is responsible for the photoresist, and the other is responsible for the photolithography machine.

How can he lose face like Beidou?

Zhang Dayuan couldn't help but look up, looked at the student who had just discussed the plan with him, and finally let out a long sigh.

It’s okay not to scold these crooked melons and cracked dates. However, Zhang Dayuan is not discouraged. In fact, he is very aware of Wu Lihong's physical and mental state. With his sickly appearance, he is likely to retreat to the second line after this time.

And my body has always been strong, so it will not be a problem for me to hold on for a few more years!

As long as you give it another try, who can't have a perfect ending?

"We've already discussed it, why are you still hanging around!?"

"Hurry up and get your work done. Get this done as soon as possible so that you can go back and continue your research on superconducting qubits!"

"..."
-

Steel City, Dahan Core Industry.

It has been almost a week since the first production line of Dahan Core Industry was officially put into production.

After this production line was put into operation, it was immediately put into full operation to produce CMOS chips used in Wuan cameras and mobile phone cameras.

But because the production team has only been established for more than two months, it has not even passed the running-in period.

Moreover, they are all using EUV lithography machines for the first time to manufacture chips with high-end processes such as 7nm. In addition, they are very unfamiliar with the analog circuitry that converts light into digital signals on COMS, resulting in a chip yield rate of only about 60%.

If the yield rate fails to improve, let alone make money, it will be good if it does not lose money.

This put Yu Jingmin, who was rushing to the shelves and served as the interim technical director of Dahan Core Industry, under so much pressure that he would often dream about conducting research experiments while sleeping, and then wake up suddenly because the experiment failed.

But fortunately, his savior has also arrived!

After Kang Chi spent three days in Pengcheng to help Warwick's imaging technology department solve most of the problems, he set off directly to Steel City, and stopped at the parking lot of Dahan Core with Wang Haowen, who came directly from the Magic City. The field converged smoothly.

"Senior Brother Wang, congratulations. I heard that you were on the list of second authors for the EUV photoresist paper?"

As soon as they met, Kang Chi smiled and held Wang Haowen's hand, "Fortunately, Teacher Wu is willing to let him go, otherwise I don't know what to do with this mess."

"Xiao Wang, Xiao Wang, just call me Xiao Wang when you are working." Wang Haowen quickly said modestly, "I can get into the second grade because Teacher Wu sees that I stay up all day and all night, and I have hard work even if I don't have any credit." I was rewarded for my own sake, so you can’t expect too much from me..."

"Really? Don't be so modest. Teacher Wu has a very high opinion of you and thinks you can play a leading role."

"It's all praise!" Wang Haowen said sternly, "You don't know, Teacher Wu likes to praise people, which puts us under a lot of pressure."

"..."

Kang Chi hesitated for a moment, "Why are you nervous? Do you know something?"

"Well...actually it's nothing. I just heard that your temporary technical director Yu Jingmin was under so much pressure that he resigned twice a month..."

Kang Chi was speechless and said, "Why do you know all this?"

"The semiconductor research and development circle is actually very small..."

Kang Chi nodded, then smiled and patted Senior Brother Wang on the shoulder:

"Actually, don't put too much pressure on you. Although Yu Jingmin has more experience in the industry than you, his experience is in normal production, and you have more R&D experience than him, and your ability to solve problems is definitely better than him, so I am absolutely relieved to leave Dahan Core Industry to you!"

"And if that doesn't work, you can also recruit reinforcements. Since they are from the academician's sect, your brothers and sisters are your resources. If you can recruit a few, that would be great. I can give you some heads." award!"

Wang Haowen: "..."
