c988 Chapter 1013 Stars and sea, brain-computer interconnection

Zheng Zhenchuan did not attend the afternoon meeting.

However, Yuanxin’s discussion on the semiconductor industry continues.

“For the past ten years, we have been competing with Intel on technology. As of last year, we have reached the mature 45nm node.” Zhang Rujin put on his reading glasses and glanced at the document in his hand, his face not very sad. Feeling: “I have to say that Intel is still very powerful. Every time we take the lead, they are always able to catch up in time and even overtake.”

“This is how Moore’s Law is realized.” Su Yuanshan added with a smile.

“Yes, but this year we can take a big step forward.” Zhang Rujin looked at everyone with a smile, but his main gaze still stopped on Su Yuanshan’s face.

After all, among the many people present at the meeting, Su Yuanshan had the deepest understanding of semiconductor technology.

“At the latest by the middle of the year, we can launch the 22nm-based finfet process to bring the transistor density of the wafer to a higher level. Moreover, our current DE technology has matured and is currently being transferred to SADP technology. From a technical perspective, it is possible Support our process to continue to explore the process under DUV conditions, or in other words, explore the equivalent process.”

//DE (double exposure, double exposure), SADP (self-aligned double patterning self-aligned double imaging)

“If Intel can’t keep up, then this will be a huge lead!” Zhang Rujin’s face was red, and he finally couldn’t help but get excited: “After the process enters 22nm, finfet will be the only choice, at least for now yes.”

Not everyone present had an understanding of semiconductor technology. Seeing Zhou Xiaohui next to him with a hesitant look, Su Yuanshan coughed lightly and explained to her with a smile: “Currently, computer chips have always used mosfet structures, eh. …To be precise, it is an NPN structure…”

Seeing that Zhou Xiaohui still didn’t understand, Su Yuanshan gave up the explanation and said directly: “Anyway, the process we talked about before refers to the channel length in the mosfet structure. The shorter the channel, the smaller the resistance and the higher the performance. At the same time, the transistor density will become larger, so the manufacturing process must be continuously improved.”

“Oh? What then?”

“Then if the previous mosfet structure is still used, when the channel length becomes shorter and shorter, such as after 22nm, the source and drain will become closer and closer, and the electric field will also become closer and closer.” Su Yuanshan said and stretched out He put his hands close and then put his notebook on his hands: “My two hands are the source and drain. The current flows in from the source and flows out from the drain, generating an electric field. When they are too close, they will interfere with each other.” to the gate above, thereby leaking electricity—we call this effect the short-channel effect.”

“The finfet structure was born to solve this problem. It even has a structure that puts the transistors upright – for example, I put up my palms – so that in addition to achieving a higher transistor density, it can also be very good. It can effectively solve the short channel effect. Therefore, from the current point of view, 22nm is a watershed in whether high-performance chips adopt finfet structures in the future.”

“What about the equivalent process?”

“The equivalent process is the number of transistors in the finfet structure. If calculated according to the mosfet structure, how many processes are needed to achieve it. For example, a chip using the finfet structure has 10 billion transistors. If it uses the mosfet structure, it will reach 10 billion. For a transistor, the channel length needs to be shortened to 14nm – so we believe that the equivalent process for this chip is 14nm.”

“Understand?” Su Yuanshan looked at Zhou Xiaohui with burning eyes.

Zhou Xiaohui pursed her lips and smiled: “I don’t really understand.”

Su Yuanshan: “…”

The group of people on the opposite side started to have fun. Ding Lei laughed and joked: “It feels like I’m dreaming back to the classroom in 1990.”

“Well, anyway, you just need to know that this craft is very meaningful, very meaningful.”

“Can we get the North Star?” Zhou Xiaohui blinked and asked curiously.

Then everyone looked at Su Yuanshan.

Polaris has been in operation for two times, and its loading rate with the current Nobel Prize is extremely high, which has raised the “competitiveness” of Polaris.

But what makes people feel a little regretful, or sighing, is that the higher the specifications of Polaris, the greater its influence, which means… the fewer opportunities there are in the country.

At least for now, this is true.

If the only promising thing is, it may be the results born under the Yuanxin system in the past ten years or so – but Yuanxin is a company after all, how can it have so many great contributions?

Everyone has counted and found that from a fair standpoint, except for Su Yuanshan, Fuji Xiong, and Xi Xiaoding who have made huge contributions in the fields of physics, flash memory, and artificial intelligence, for now, there may be only one proposed Tang Wenjie of finfet structure.

After all, Tang Wenjie has previously won the IEEE’s Solid State Circuit Award and the Paul Rappaport Award – both awards are awarded to scholars with “outstanding contributions”.

Su Yuanshan was startled, then spread his hands: “Don’t look at me… It doesn’t matter what I said… But I personally think… senior brother is still qualified.”

As he spoke, Su Yuanshan glanced at Zhang Rujin and added: “And from the perspective of an engineer, I think it is equally important to propose theories and implement processes.”

Zhang Rujin smiled and nodded after hearing this.

——Of course he was not doing it for himself, but for Liang Mengsong who was busy day and night in the factory.

…

“Okay, let’s move on to the next agenda.”

After finishing the topic of semiconductors, Su Yuanshan directly took control of the meeting. This time, he looked at Xi Xiaoding.

“There are already companies abroad that are working on the research of recyclable rockets, and China also loosened its grip on private aerospace last year, so… it is time for us to start the pace of aerospace.”

“Of course, due to institutional issues, we cannot and do not need to compete with the National Space Administration for the space station or the moon landing… It is even less possible to shout slogans about colonizing Mars – being down-to-earth is in line with our current actual situation. Therefore, Focusing on the research and development of commercial rockets, especially the development of high-thrust, recyclable commercial rockets, is a more suitable path for us to take now.”

“In addition, we must also actively consider the next industrial revolution.”

“New energy, new production methods, new lifestyles – this is my understanding of the next industrial revolution that will change the destiny of mankind – although there are currently many voices proposing a variety of standards, such as faster and updated communication technologies, For example, the Internet of Things, new energy, further revolution in informatization, intelligence, etc… There is still a consensus… But in my opinion, these are old clichés.”

Su Yuanshan sighed as he spoke: “The industrial revolution, in the final analysis, still depends on energy, and this energy cannot be the current concept of new energy – the so-called new energy now can only be regarded as clean energy. Real new energy , it should be controllable nuclear fusion, and it must be controllable nuclear fusion that is fully mature in cost and technology.”

“Then let’s do controllable nuclear fusion?” Li Mingliu said immediately, but then he glanced at the people around him and frowned: “It seems no one can do it?”

“…We are a company, and we must invest money in schools and scientific research institutions.” Su Yuanshan glanced at Li Mingliu speechlessly and opened the notebook again.

“Then there’s visual simulation technology.”

Su Yuanshan said and looked at the group of people in the Internet field opposite.

“Stars and the sea, brain-computer interconnection, these are two paths for the future of mankind, you choose one.”
