Fortunately, Ning Zi noticed the movement outside and walked to the table where the microphone was placed.

"Everyone is here. The one on the left is the changing room. After changing clothes, go straight to the air shower room. Come in and talk."

No one was polite, the six academicians immediately filed into the changing room, leaving Chen Yonggang and Liu Si outside.

"Liu Si, why don't you go in with the experts to have a look?"

"I'm not going to cause trouble, just wait for the news here. But Lao Chen, have you figured out what's going on?"

"Liu Si, it's really good of you to ask this question. To be honest, if I can figure out this stuff, I can be an academician, right?" Chen Yonggang pouted.

……

Not long after, several academicians had already walked into the chip testing laboratory.

They were all pragmatic people, no one exchanged pleasantries, but gathered around Ning Zi, looking at the chips on the plate.

You Wanli was the first to ask, "What kind of chip is this?"

"NB-10T, narrowband chip."

"Is this the Flip chip packaging technology used?" The expert from the Institute of Semiconductors then asked.

"Correct."

"How much is the manufacturing process?"

"Well, if this standard is based on the process level announced by Intel, it is 180nm, but because of the different structure, it should not lose to the current mainstream 60nm process. Of course, on this scale, the process upgrade can be very fast. Alright , It is meaningless for us to discuss these now. Everyone, the testing equipment is ready, I will go out first. So as not to affect your testing, if there is any problem, let's go out and talk after the testing is completed. By the way, this chip The instruction manual is here, if you have any questions, you can read the instructions first if you are not sure."

Ning Zi took the initiative to speak.

Several people looked at each other in blank dismay, and then acquiesced to Ning Zi's opinion.

After all, it would have made them feel a lot easier if that unbelievably young face wasn't there during the test.

Ning Zi left, and their work began.Fortunately, Ning Zi thoughtfully kept the unpackaged chip, but being rigorous, they decided to dismantle the packaged chip, and soon they assigned tasks and started to get busy.

"I... you guys come over quickly and take a look, is this thing really a three-dimensional structure?"

Yes, two chips left by Ning Zi have already started performance testing, and two chips are directly used to observe the internal structure.

At this time, following the words of the whole academician, the other five people temporarily put down their work at hand, walked over here, and stared at the internal structure displayed on the monitor after being magnified by the microscope.

"Huh? This design is quite novel, isn't this the design of the base gas tube?"

Yes, at this time, the object is the neatly arranged tubular silicon according to certain rules, and the inner and outer parts of the silicon tube are clinging to densely packed transistors.

"How do these channels exchange information? Look at it from another angle."

Hearing this sentence, Quan Maoguo began to operate, and soon the answer to the mystery was revealed.

"This is in line with the manual. The base lines are connected by through pipes, but in this design mode, it is difficult to dissipate heat in the middle part? It is good for narrowband communication. If you really want to use this structure to design the CPU, In the case of high-frequency work, heat dissipation is a big problem."

"Wait, let me read the manual. Just now I seem to have seen the heat dissipation part in the catalog of the manual...I found it, and Lao Quan adjusted the angle again, tilting it at a 45-degree angle...Yes, look, it is here, see the edge The carbon nanobeams, right? The instructions say that this design can overcome the thermal resistance of the interface. There are four lines on the edge of the outer wall of the TSV and the inside of the TSV. Here, it is filled with carbon nanotubes. It is said that the thermal conductivity of this material is much higher than that of traditional materials. , the heat is easier to be transmitted, which belongs to a new all-carbon heat dissipation structure. The efficiency is extremely high."

"If it really has such a high heat dissipation efficiency as the manual, then this will be amazing."

……

Several people discussed the structure diagram for a long time, and finally someone remembered that there was still a test to be done, so the people began to gradually disperse, and only You Wanli was left here in the Maoguo, researching the internal structure over and over again.

Until another startled voice sounded next to it: "How is this possible? How can its output noise be so small? It is more than 30.00% smaller than traditional silicon chips?"

You Wanli and Quan Maoguo looked at each other, and the two couldn't sit still at the same time...

Chapter 164

In the chip testing laboratory, several experts got together again, and everyone looked at the monitor showing the analysis results again.

"The output noise is smaller than the traditional classical structure? How is it possible? With so many tubes working together, it should be higher."

"That's right, old Zhu, are you making a mistake?"

"How could it be wrong? I checked the instrument repeatedly, you can see the result yourself! If you don't believe it, there is still a chip over there, you can do it again."

"Huh? The output noise is really small? How did you do it? Or is it an example?"

"Come again, come again, you have to figure out the reason."

So several people started busy again, and soon the proofreading results came out.

"Old Zhu is not mistaken. The output noise is indeed smaller than that of the classic structure. The reason is also found. The chip adopts the way that the signal and the ground are arranged at intervals. This is a dynamic working model, signal injection, set the peak value of the signal to 1V, and the period They are 1 ns and 0.1 ns respectively, the rise time and fall time are 4% of the cycle, the duty cycle is 0.5, the signal line is connected to the lower end of the open circuit, and the upper end is connected to a 50Ω load. According to the calculation results of the circuit model, the peak crosstalk noise affects its performance. The impact is almost negligible. Because even under its full-load operation, adjacent signal processing is always arranged at intervals, that is, two sorts of internal and external. "

"What about the impedance parameter?"

"Here, it is only calculated by the formula that comes with the instrument. If the result is accurate, it means that this carbon nanotube bundle channel filling technology can improve signal transmission performance. Here, the influence of quantum capacitance can basically be ignored. Only the resistance and inductance Change. This thing is ahead of an era. The key is that I haven’t seen carbon nanotubes with this performance in magazines before. Whose product is this? Is it energy-produced? Does anyone know?”

Several people looked at each other in blank dismay. From their attitudes and expressions, everyone could see that the other party did not know that material science had made such great progress in this area.

"Well, let's not talk about whether it can be mass-produced. It's amazing that this thing can be designed, okay? No, shouldn't we clarify the focus of our work, first test the performance of the chip, the 180NM process level , can achieve this kind of work efficiency. The noise output can be controlled so well, and more importantly, this structure is indeed unprecedented. Although silicon has not been completely abandoned, the main body of the chip is already a carbon structure! Everyone, there is no patent shackles , Breaking from 180NM to 1NM, what does this new structure chip represent, do you all understand?"

Well, these words stunned everyone.

In the frenzied work atmosphere just now, no one really thinks about these things, but now that they are brought up, a group of bigwigs in the industry only need to use scraps of their brains to understand what this means.It is no exaggeration to say that the establishment of the World Semiconductor Alliance and the related policies promulgated have already become dispensable to China because of this epoch-making technology.It can even be said that it will be of great help to Huaxia to independently embark on another chip road.

Don't even have to wait that long.

After this new structure is exposed, the other party probably won't have enough confidence to formulate various policies...

"Yes, I just don't know if the design of large-scale integrated circuits is supported now. This is a simple narrowband chip after all." Quan Maoguo said regretfully.

"No, Lao Quan, who said in the car just now that if it is really a brand new structure, then even the simplest power management chip can be designed. No matter how simple this narrowband chip is, it is better than only a few Is the PMIC of the circuit much more complicated?"

"This...haha, isn't this a higher requirement after seeing hope...By the way, do you feel hungry?"

"Wait, it's already past three o'clock in the afternoon? If you didn't tell me, I really didn't feel hungry, and the laboratory didn't even notify me?"

"Okay, let's go here first today? There should be more than a few chips that have been made here. I will ask Ning Zi later to see if there are any more. Take it back to the institute and study it more carefully."

"Are people willing to give it?"

"Hey, it shouldn't be so, and we don't have any interests."

"Uh... Well, Lao Quan, do you think it would be a little sudden to talk about technology transfer with Ning Zi today?"

"Hey, Xiao Sun, do you want to help Datang Precision get the technology? I guess if you really have this idea, don't care if it's sudden or not. It's best to mention it today when Liu Si is here. , otherwise it might be a fight between gods after two days."

Although the six academicians, who are more than 300 years old together, are talking non-stop, they are doing the finishing work in an orderly manner.

Although a few people rarely work in the front-line laboratories, it can be seen that the business capabilities have not been completely discarded. Soon, the laboratory was restored to its original state according to the laboratory standards, and the chips used for testing were also in accordance with the laboratory standards. The requirements written on the wall were put into the designated container, and then they walked out of the laboratory together.

……

Outside the R&D center, Chen Yonggang had already accompanied Liu Si to walk around the green belt in the R&D center several times after lunch.

When it was time for lunch, Chen Yonggang hadn't thought of telling the academicians in the lab to eat before working, but the problem was that before entering the lab, communication products such as mobile phones were left outside.It is too troublesome to enter the laboratory, and there is no way to notify the inside from the outside. For Chen Yonggang and Liu Si who are not familiar with the operation of the laboratory, there is really no way to notify the inside.

Yes, Ning Zi is not here, he has to go back to school to rest first because he is too tired to study chips in retreat recently.

This reason can be said to be impeccable, and no one can find a fault.

In fact, Liu Si wanted to pull Ning Zi to ask more questions, but after all, he was not very familiar with Ning Zi, so he gave Chen Yonggang a wink, and the headmaster just pretended not to see it. Follow Ning Zi and walk away.

No way, speaking of it, he really couldn't grasp Ning Zi's place.

Liu Si also knew that Ning Zi probably didn't think much of the country's appropriation.After all, this is a young man who may pay trillions in taxes.People can do anything to compete for a project, and this person can invest an additional [-] billion in other people's projects, just to poach people.

To be honest, it is surprising that this guy is willing to retreat and study chips.After all, if billionaires want to enjoy life, they have too many choices.

Fortunately, the expert testing team can still be trusted.

As a result, it was noon and no one came out yet.With the mentality of keeping the results secret temporarily, Liu Si actually didn't want to disturb the work of the high-end academician group, so Chen Yonggang simply asked someone to bring an insulated box and prepared meals for the academicians.

Staying in a closed environment only made people feel stuffy, so the two simply went for a walk in the green belt outside the research center.

"Old Chen, I just observed that there are not many people going to eat in the cafeteria at noon? I counted them when we were eating, and there were more than 50 people served. Such a large research and development There are only more than 50 people in the center?"

"Oh, the research group, how many people will go to the cafeteria to eat on time? Many of them are sent by a laboratory, and they are brought directly to the entire laboratory."

"I've observed this too. How can there be as many people as you said? There are only a dozen or so people who brought food."

"Haha, Liu Si, you also know that this research and development center has just been opened, and it is normal that there are few people. It is also constantly recruiting people, but it is still difficult to find excellent research talents. Otherwise, it would not have followed Shuangdan University has become like that."

"Don't talk about other things, let's talk about the key points. So with just a few people, you have overcome a problem that has plagued us for decades? And bypassed all patent barriers?"

"Well, what should I say about this matter? Although I don't understand it very well, doing research doesn't depend on a large number of people, right?"

After hearing this, Liu Si glanced at Chen Yonggang, wanting to refute this obviously unprofessional statement, but he didn't know how to speak for a while.

After all, those experts have entered the laboratory and have not yet come out, which is actually very telling.This time, Ning Zi’s achievement has not been announced to the outside world. If Ning Zi was just deceiving, like someone who simply rubbed off other people’s product logos, it should have been discovered long ago.

In other words, the longer the experts stayed in the laboratory, the less likely it was that Ning Zi would cheat.

Fortunately, the timely ringing of the phone saved Liu Si from embarrassment.

"okay."

After answering a few simple sentences, Liu Si looked at Chen Yonggang and said, "The experts are here, let's go back quickly."

"Hurry up! This way, this way..."

……

"Academician You, all academicians, why are you two alone? What's going on inside?"

As soon as they walked into the rest area outside the laboratory, Liu Si and Chen Yonggang only saw You Wanzhang and Quan Maoguo sitting at the table eating, but did not see the other four academicians.

"They called, why are you the only ones? Where's Ning Zi?"

You Wanzhang ignored Liu Si's question and asked directly.

Naturally, these two people were not what they wanted to see the most at this time. Every academician had a lot of questions to ask Ning Zi.

"Oh, Ning Zi said he was too tired, so he went back to school to rest first."

Hearing Liu Si's words, Quan Maoguo put down his chopsticks and said in a muffled voice, "Rest? How can he rest at this time? How can he sleep at his age? Why don't you leave him in the laboratory inside?"

This sentence directly silenced both Liu Si and Chen Yonggang.

Just leave people behind?In whose name?

"Uh, all academicians, let's not talk about this for now. Let me introduce what's going on. Everyone is waiting to hear your conclusions."

You Wanzhang glanced at the opposite friend who was jumping in anger, and took the initiative to take over the conversation: "The situation is like this, the chip designed by Ning Zi is actually nothing to say. The NB10 type narrowband chip is purely from the perspective of manufacturing technology. The low-end chip type, the manufacturing process is only 180NM, but he did find a new way to design a new structure and use new materials. Simply put, in addition to silicon, CNT materials are also used. The key point is here, according to The specific test results show that the working efficiency of this new chip structure is much higher than that of the current traditional silicon-based technology.

Most importantly, although the chip designed this time is very simple.But we can determine that this structure has the potential to be used in the design of large integrated circuits.In other words, this three-dimensional structure can be used in products such as CPUs, GPUs, and various storage arrays.Of course, the process needs to continue to advance.But as far as the current situation is concerned, although the chips manufactured by Ning Zi in the laboratory only use the 180nm process, their performance is already comparable to that of similar products produced in the market using 60nm technology.

In other words, this is no longer Huaxia's breakthrough in the field of chips, but a breakthrough for all mankind in the entire field of semiconductor technology. Note that I am talking about the entire field!Because the chip has been manufactured or taped out, it means that all the problems that need to be overcome from design to manufacturing have been solved, and then only the work of continuing to advance the technological level remains.It is no exaggeration to say that this technology represents the future of the semiconductor industry chain.As far as I know, whether it is Intel, IBM, AMD, or other semiconductor companies, they have been researching silicon alternatives.

Because the atomic radius of silicon is much higher than that of carbon atoms, in other words, on a smaller scale, the technology proposed by Ning Zi has more potential. 1 nm lower limit.But how does Ning Zi achieve it now, such as what software is used for design?What processes are required for production?Is the material productive?We don't know what equipment is needed, we only know that this thing has already been made.So you understand? "

Liu Si understood, You Wanzhang's words were obviously more convincing than Chen Yonggang's.

This was a comprehensive opinion given by a group of top Chinese experts. At this moment, Liu Si probably understood why the other four academicians wanted to call.After all, these people are different from You Wanzhang and Quan Maoguo, and they are all connected to companies that operate semiconductors commercially.He reckoned that it wouldn't be long before the capital city would be bustling. After all, this is a world-leading technology.

In fact, Liu Si's reaction was correct, because just as he thought of this, the phone rang.

After looking at the phone number, Liu Si's expression also became serious. He glanced at Chen Yonggang and the two academicians who were beside him. Holding their mobile phones, they walked outside the door temporarily before answering the phone.

"Hey, Liu Peiyi, the newly established chip research and development center of the University has developed the world's leading chip technology?"

"Well, Mr. Chen, I also just finished consulting with Academician You and am planning to report to you. Where did you get the news from?"

"There is a meeting in the afternoon, and the chairman asked for leave after answering the phone call. How can I not know? What is the situation now?"

"If Academician You was not joking just now, Ning Zi provided a brand new semiconductor solution, involving the entire semiconductor industry chain. But the more specific situation is still unclear, because Ning Zi said that he was too tired and went to rest .”

"Going to rest? I... so, are you still in the R&D center of the University of Sports?"

"um, yes."

"Go and find Ning Zi, see when he has rested, and invite him to the ministry to chat with everyone. Hey, forget it, so, you tell Chen Yonggang that the evening meeting will be held at the University of Sports, let He has coordinated well, Ning Zi should have a good rest at night, right?"

"Okay, I'm going to discuss it with Principal Chen."

"What else are you discussing? Inform him directly, this matter must be implemented."

"Row."

……

Huaqing University.

At this time, Huaqing has also entered the exam season. For a key university like Huaqing, the atmosphere of the final exam is naturally more tense.After all, grade points are very important, and this is a major event directly related to future graduate studies or studying abroad.

In the principal's office, Zhou Jingxue was also not idle. He was reading a document about in-depth and substantive global school-running cooperation and exchanges with UC Berkeley.This is also one of the work contents that he needs to advance in the next summer vacation.
