Ning Xiao's phone call was naturally made to Chen Yonggang.

There is no way, newcomers to the laboratory are like this, and it is not clear who to report to when the results are produced, so they can only talk to people who know how to do it. Chen Yonggang should understand, after all, he is an old man on the education line, even if he has never eaten pork, he must have seen a pig run.

But in fact, Chen Yonggang didn't know very well, after all, he really didn't think that there would be such a thing before. Generally speaking, the achievements of the sports university are praised for sports. The way to report his results is naturally to report the good news to his old leader in the General Administration of Sports.

Today's situation is different, after all, it is an achievement in the cutting-edge field of natural science, and it is also the result of the key project of Huaxia Nuclear High-tech Foundation. Although Chen Yonggang didn't know who to report to, he was an old man in the education line after all, and he knew very well that if the results were real, it would not be a question of who to report to at all.

Especially in the current situation, he only needs to send out the news, and it is very feasible to change who will come to the Tida Chip R&D Center to listen to the report.

Of course, the premise is that Ning Xiao is not joking with him.

In fact, many people felt that Ning Xiao's retreat was a joke on everyone.

Both domestic and foreign.

For example, Conan Lamar came to talk to him very seriously about the complex process of chip design to manufacturing, just to make Chen Yonggang believe in a conclusion, and came forward to persuade Ning Xiao not to waste time on delusions, and quickly came out of the laboratory to discuss those mathematical propositions together is the true meaning of life.

Obviously, Conan Lamar didn't know much about the relationship between Chen Yonggang and Ning Xiao.

At least when the two were chatting, although Chen Yonggang smiled and said with certainty that he would definitely talk to Ning Xiao about this matter, and strive to make Ning Xiao give up his boundless ideas as soon as possible and return to the right path. But in fact, after politely sending Conan Lamar out the door, Chen Yonggang put the matter behind him.

What kind of international jokes, if Ning Xiao is really willing to listen to him in everything and obey him, then his level will not be too much, and it will not be a problem to jump up two levels.

Of course, there are many people who hold the same opinion, so even if Chen Yonggang has confidence in Ning Xiao, he doesn't think that a job that may require an investment of trillions and thousands of top intellectual engineers can be tinkered with by Ning Xiao alone in the laboratory.

But now the phone call directly put Chen Yonggang in a state of doubt about the world.

And that's it?

From the night when Ning Xiao announced that he would go to the laboratory for retreat, to today, it was only two weeks and three days, and now Ning Xiao told him that he had made the chip out of the laboratory alone?

This made Chen Yonggang not know what to do for a while, so he could only ask tentatively: "This, Ning Xiao, what do you mean by saying that you seem to have made it?" You should know that this is important, right? If we announce this news, there may be no turning back, especially in the current public opinion environment, which will cause ridicule. ”

"Principal Chen, it seems that he is actually humble. I think it might sound a bit proud to say it directly. ”

Chen Yonggang subconsciously swallowed his saliva and let out a "grunt", this "self-humility" made him feel very wrong. But I can't go into details.

"In this way, Ning Xiao, although you are confident, I think we should be cautious, you said that the chip has been made, does it mean that the chip has been actually produced in the laboratory?"

"That's right."

"That's why don't you do that, I'll find some experts to test it first, make sure there's no problem, and then we'll report to the top, how about it?"

"Two questions. First, President Chen, do you have a good personal relationship with Huaxia's chip experts? Found a way to make sure they don't talk nonsense? Second, to tell you the truth, I'm an expert in this area, and I've tested it. Don't think about it so much, just talk to the management you think is suitable, and they will naturally find someone to verify it. In this way, after you finish your report, come directly to the laboratory to find me, and I will tell the security department of the center that I will let you in later. ”

"That'...... I'm really just going to talk about it, no kidding. ”

"Hmmm! Don't worry, Principal Chen, I've never liked to joke. ”

……

Hanging up the phone, Chen Yonggang stroked the table, first calmed down, then gritted his teeth, and began to look for someone in the mobile phone address book.

To be honest, Chen Yonggang, who has made up for half a month's knowledge of chips, also thinks that this matter is very unscientific, but whether this matter is scientific or not is not up to him, anyway, he is just a microphone. And if he really wants to talk about it, he should also cherish this rare opportunity to experience.

Because if it turns out that the chip developed by Ning Xiao is indeed reliable, then it is estimated that he will not be needed to be a microphone in the future. Xiao Ning will have enough channels to directly make appeals and report the situation.

So after finding the number, Chen Yonggang did not rush to dial out, but closed his eyes, took three deep breaths, and silently brewed emotions, and then pressed the dial-out button.

"Hey, Liu Si, good news, great news, under the leadership of our outstanding student Ning Xiao, with the full cooperation of the school, the chip R&D center of Yanbei University of Physical Education has finally successfully developed a new chip manufacturing technology in recent days after months of hard work, overcoming difficulties, and working hard day and night. But it is also a big step in the development milestone of Huaxia chip technology! ”

Chen Yonggang is satisfied with the statement just made.

At the very least, it is very enthusiastic, and the words are very accurate, highlighting both the individual and the collective......

However, only a confused response was received.

"What? Have you developed a chip manufacturing technology? What is the technical principle? Or is it silicon? Where is the innovation? Did the lab produce a physical chip? Has the package been tested? What about performance? ”

Chen Yonggang suddenly realized that he had just made emotional preparations, and he did not expect that there were so many questions to answer.

In fact, it can't be blamed that this Principal Chen is not professional enough, mainly because Ning Xiao's attitude was too light-hearted when he informed him of the news, and he was too brief, and he didn't bother to explain too much to him. And he was really shocked just now, he didn't even think to ask these details, and even more irritably, even if he did, he didn't know what to ask.

After all, what normal principal would understand such a thing as semiconductors.

He can only answer one of the above questions...... No, it seems that one can be answered.

So, Chen Yonggang immediately began to play: "No, Liu Si, I can't answer you so much." That's right, the physical chip has been produced and tested, and as for the rest, you may need to come to our R&D center to do some further understanding. Well, it's best to bring the relevant experts with you. ”

"No, since you've said so, I'm definitely going. But you have to make it clear first, what kind of chip is the physical chip? Universal chips? Dedicated chips? What can I do? ”

"I don't know. Hey, Liu Si, I'll tell you the truth. Didn't you say that you went to the laboratory of the chip R&D center for retreat some time ago? Then he suddenly called me this morning, and his original words were that he had made a new heterogeneous three-dimensional chip in the laboratory that could bypass all foreign patents at this stage, and it had been produced and tested, at least he was very satisfied with the test results, so he immediately informed me. As for the others, Ning Xiao didn't say it, probably because he thought I didn't understand it. ”

"Yes, Chen Yonggang, you, the principal are really comfortable. Forget it, I won't tell you, I'll immediately organize experts to go over and take a look. About an hour later, I will be at the height of the body. ”

As soon as the voice fell, the other side hung up the phone.

Chen Yonggang listened to the busy tone on the phone, and he was actually very unconvinced.

Whoever said that he was comfortable as a principal was really too much, and he obviously had a heart that couldn't be all day long.

Of course, being unconvinced is a matter of moments. As a principal, the ability to grasp the key points is naturally strong. It doesn't matter if he, the principal, is comfortable or not, the important thing is that people will be coming in an hour. He had to take a quick look before he could rest assured.

In fact, he had planned to report the situation to many leaders.

But a few questions from Liu Si, who was in charge of related technologies just now, made him temporarily dispel this idea.

The good news is not in a hurry, it is better to wait for the expert to confirm it, and he will call to report the good news as soon as possible.

In this way, at least the leaders will not be so ignorant if they have the knowledge to ask.

……

With Chen Yonggang's call, countless signals began to be transmitted. Liu Si obviously understands who to talk to to to listen to the situation report at this time, and understands how true this news is.

It's not that Liu Si has more confidence in Ning Xiao than Chen Yonggang, the main thing is that Ning Xiao's reputation is there, as the youngest mathematician and computer scientist in China, he has given this news and paid more attention.

……

The first to receive the notice was Academician You Wanzhang of the Beijing Institute of Microelectronics of the Chinese Academy of Sciences. Academician You can be said to be one of the people with the deepest research on microelectronics and inheritance circuits in the official research institute of China, and has been engaged in the research and product development of high-performance chips such as CPU and Flash in many world-class chip companies such as AMD, IBM, and Sandisk 20 years ago.

Five years ago, because of some unreasonable treatment abroad, You Wanzhang was finally invited by Huaxin International to return to China to serve as the chief technology officer of Huaxin International at that time. It's just that he later disagreed with the chairman of Huaxin International at that time on the development of Huaxia chips, so he simply jumped to the Institute of Microelectronics, specializing in the research of integrated circuits.

During the period when the World Semiconductor Alliance was established and a series of rules were issued, Academician You naturally became one of the most consulted elders, and during this time, various emergency meetings were attended almost every day. So it was not surprising that he received a call from the director of the Department of Science and Technology early in the morning.

But after listening to Director Liu's words, You Wanzhang didn't know what to say for a while.

"No, Director Liu, Chen Yonggang's original words are new heterogeneous chips that can bypass all foreign patents at this stage? And it's a three-dimensional chip? He's kidding, right? ”

"Oh, Academician You, this is really not President Chen's original words. In his words, it was Ning Xiao's original words. ”

"Ning Xiao, I know, the young man is very good, but how long has it been since Apple helped build that chip R&D center? I only heard about the official opening last month, and I was invited to visit. But now that such a big result has been said, can you really believe it? ”

You Wanzhang really can't be blamed for asking so rhetorically.

In fact, the more people who know about semiconductor technology, the more they understand how difficult it is to design a technology that can bypass all patent blockades and produce chips.

The world's chip development technology tree has been lit very high, and the technology moat of the silicon-based semiconductor industry is almost unbreakable. As for heterogeneous, three-dimensional, and so on, it's even more difficult. The nature of silicon makes it difficult to have a brilliant design at the three-dimensional level, and FI gate technology has almost taken it to the extreme.

As for the new material...... That's even more of a joke.

At a time when Moore's Law is about to fail, so many materials institutes around the world are hoping to find an alternative to silicon, after all, the atomic radius of silicon is still relatively large compared to carbon. This also means that at smaller scales, silicon is more susceptible to interference from quantum laws. In fact, at the latest 7nm process level, countless engineers are already racking their brains to overcome various quantum effects at a tiny scale, such as quantum Suichuan.

So if you can find a better material than silicon, you can immediately make those researchers world-renowned scientists and win various scientific awards, such as the Nobel Prize. In addition, it will be sought after by countless technology companies. Intel, IBM, AMD, NVIDIA, Texas Instruments, Hynix, Samsung, etc., these large companies will never be stingy with their checks, and will not hesitate to poach such people into their own companies.

It's not that these companies will immediately launch heterogeneous material technology, in fact, even if there is a new material and new development direction, these companies will not immediately release this technology, but will use it as an investment in the future, as their own technology accumulation. Wait until the last drop of profit has been squeezed out of silicon-based technology before rolling it out to the public.

However, even though everyone knows that the future and money in this direction are immeasurable, and the research in this area is in full swing, so far You Wanzhang, a laboratory that can provide stable and reliable materials for continuous research and development, has not heard of it.

Until today, he suddenly heard such an incredible news from Liu Si's mouth, and he had been immersed in the research of this field for a long time, which made him refuse to believe the news.

"Academician You, if you want to ask me, then I don't dare to believe it. If it was really so simple to engage in chips, we would not be so caught off guard during this time, and we would have meetings every day. But since people informed the news early in the morning, no matter whether it's true or not, you have to take a look to find out, right? And Ning Xiao should know that this kind of thing can't be joked about, maybe there will be unexpected surprises? ”

"That'...... Okay, too. You have to go and see it first, by the way, the R&D center of the University has a very advanced chip testing center, and the instruments in it are very advanced. You Wanzhang reluctantly responded.

If it weren't for the chip R&D center that Apple helped build to the University, it was indeed advanced enough, and he really didn't bother to waste time on this trip. After all, if the news is true enough, then he will feel that he has lived to a dog for most of his life.

I have studied semiconductors all my life, and no one can achieve great results in a month...... Not to mention that at present, Ning Xiao's most praised achievements are still in mathematics and algorithms.

"Don't worry, Academician You, on your side, the semiconductor institute, and the representatives of the company, I plan to form a delegation of six experts to go over and have a look. After all, I don't know what the situation is yet, and it's not good to make too much fanfare, right? ”

"Well, six people are enough, but I suggest calling the full academician, he has a unique way of testing."

"It just so happens that Academician Quan Maoguo is also on my list. Are you waiting at the institute for me to send a car to pick you up or? ”

"Is it convenient?"

"Just along the way, I'm going to pick it up anyway."

"Okay then."

"I'm coming soon, I'll be there in twenty minutes at the latest."

"Okay."

……

Twenty minutes later, You Wanli boarded a special car to pick him up.

There were already five experts in the car who were seen every day these days.

"Lao You, sit here, a special place for you." It was Quan Maoguo of the Semiconductor Institute who greeted You Wanli, and the two were good friends.

After sitting down, the car started up, and several industry leaders also began to discuss.

"Lao You, tell me, what do you think of this?"

Apparently several people had already discussed it in the car before.

"How else can you see it, it's only been more than ten minutes since then, and I'll look at it later." You Wanli glanced at Liu Si, who was sitting in front of the co-pilot, and replied casually.

"Academicians, in fact, I don't think there is a need to be too pessimistic, maybe there will be a real surprise later?" Liu Si, who was sitting in front, turned half of his body and said with a smile.

The words of the two also made several academicians in no mood to continue the discussion.

Whether it is a surprise or a fright, it is a matter of twenty minutes, and there is really no need to dwell on it.

However, when he heard Liu Si's words, You Wanli knew that the judgment of these people in the car was probably the same as him.

After all, this thing is really unscientific.

……

Soon the car was inspected and entered the R&D center.

As soon as Liu Si got out of the car, he saw Chen Yonggang, who had already come out to greet him.

"Welcome ......"

"Don't come to these vain things, be pragmatic today, what about Ning Xiao?"

"Inside, I said that I should prepare all the instruments first and warm them up, so as not to delay the time when the expert team comes."

"Then let's go straight in."

"Yes, yes, don't talk that nonsense."

A group of academicians in the back echoed one after another, obviously no one was willing to continue to greet Chen Yonggang outside.

Of course, for these academicians, President Chen is indeed not enough.

"Then I won't talk nonsense, everyone, please."

……

Soon, the six experts saw Ning Xiao in a white lab coat in the laboratory.

This time, Chen Yonggang couldn't make an introduction, because Ning Xiao was in the laboratory, and he could only take a group of experts outside and watch the people inside busy through the spotless glass.

Fortunately, Ning Xiao 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, change clothes, and go straight to the air shower room. Come in and talk about it. ”

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

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

"I'm not going to make a mess, just wait for news here. But Lao Chen, have you figured out what the situation is? ”

"Liu Si, it's really good for you to ask this. Speaking from the bottom of my heart, if I can figure this thing out, I can also be rated as an academician, right? Chen Yonggang pouted.

……

It didn't take long for several academicians to walk into the chip testing laboratory.

They are all pragmatic people, no one greeted anything, but gathered around Ning Xiao and looked 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.

"Yes."

"What's the process?"

"Well, if this is based on the process level announced by Intel, it is 180nm, but because of the different structure, it should not be inferior to the current mainstream 60nm process. Of course, at this scale, the process upgrade can be very fast. Okay, so there's no point in talking about that now. Everyone, the testing equipment is ready, so I'll go out first. So as not to affect your testing, if there is any problem, we will go out and talk after the test is completed. By the way, the manual for this chip is here, if there is any problem, if you are not sure, you can read the instructions first. ”

Ning Xiao took the initiative to speak.

Several people looked at each other, and then acquiesced to Ning Xiao's opinion.

After all, if the young face at the time of the test is not there, it can also make them feel a lot more relaxed.

Ning Xiao left, and their work began. Fortunately, Ning Xiao was very intimate and kept the unpackaged chip, but rigorously, a few people still decided to dismantle the packaged chip, and soon several people assigned tasks and began to get busy.

"I ...... Come and see, this thing is really three-dimensional? ”

Yes, the two chips left by Ning Xiao have already begun to undergo performance tests, and the two are directly used to observe the internal structure.

At this time, with the words of the full academician, the other five people temporarily put down their work and walked here, staring at the internal structure magnified by the microscope displayed in the monitor.

"Huh? This design is novel enough, this is the design of the base plus the pass pipe, right? ”

Yes, at this time, the eye is a tubular silicon arranged according to a certain law, and the inner and outer parts of the silicon tube are clinging to dense transistors.

"How do these channels communicate information between them? Look at it from a different angle. ”

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

"This is in line with the manual, and the lines on the substrate are connected through the pipe, but in this design mode, it is difficult to dissipate heat in the middle, right? It's okay to do narrowband communication, but 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, I'll read the manual. I seem to have seen the heat dissipation part in the manual directory just now...... I found it, and I adjusted the angle again, tilting it at a 45-degree angle...... Right, look, this is it, see the carbon nanobeam on the edge, right? The manual says that this design can overcome the interfacial thermal resistance, and there are four lines on the edge and inside of the silicon vias on the outer wall, which are filled with carbon nanotubes, saying that the thermal conductivity of this material is much greater than that of traditional materials, and the heat is easier to be transferred, which belongs to a new all-carbon heat dissipation structure. Extremely efficient. ”

"If it's really as efficient as the manual, then that's amazing."

……

Several people discussed the structure diagram for a long time, and finally someone remembered that there were still tests to be done, so the people began to disperse gradually, and only You Wanli was left alone here on the side of the whole Maoguo, studying the internal structure over and over again.

Until another startled voice sounded next to him: "How is this possible?" How can its output noise be so small? It's more than 30 percent smaller than traditional silicon chips. ”

You Wanli and Quan Maoguo glanced at each other, and then the two of them couldn't sit still at the same time......
