The end of technology.

Ning Zi's call was naturally to Chen Yonggang.

There is no way, newcomers in the laboratory are like this. They don't know who to report to when they produce results, so they can only talk to someone who knows 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 pigs run away.

But in fact, Chen Yonggang didn't know too well, after all, he really never thought of such a thing before Tida.Generally speaking, it is the sports line that is praised for the performance of the body.The way to report the results is naturally to report the good news to his old leader at the General Administration of Sports.

The situation today is different. After all, it is the result of cutting-edge fields of natural science, and it is also the result of a key project of Huaxia Nuclear High Base.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 true, it was not a question of whom to report to.

Especially in the current situation, he only needs to send out the news, and it is also feasible to change who will listen to the report from the chip research and development center of the body.

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

In fact, many people think that Ning Zi's retreat is just a joke.

Whether domestic or foreign.

For example, Conan Lamar came to talk to him seriously about the complex process from chip design to manufacturing, just to convince Chen Yonggang of a conclusion, and came forward to persuade Ning Zi not to waste time on delusions, and hurry up from After coming out of the laboratory, everyone happily discussing those mathematical propositions is the true meaning of life.

Obviously Conan Lamar doesn't know much about the relationship between Chen Yonggang and Ning Zi.

At least when the two of them were chatting, although Chen Yonggang smiled and said calmly that he would definitely have a good talk with Ning Zi about this matter, trying to make Ning Zi give up his futile thoughts as soon as possible and return to the right path.But in fact, after sending Conan Lamar out of the house politely, Chen Yonggang put the matter behind him.

What an international joke, if Ning Zi 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 still many people who hold the same opinion, so even if Chen Yonggang has confidence in Ning Zi, he doesn't think that a job that may require investment of trillions and thousands of top intellectual engineers can be done by Ning Zi alone. The room was fiddled with.

But the call he received now directly put Chen Yonggang in a state of doubting the world.

This is it?

Since Ning Zi announced that he would go to the laboratory for retreat that night, it has only been two weeks and three days, and now Ning Zi told him that he made the chip in the laboratory alone?

This made Chen Yonggang not know what to do for a while, so he could only tentatively ask: "Well, Ning Zi, what do you mean by saying that it seems to be done? You should know that this matter is very important? If we put When this news is announced, there may be no turning back, especially in the current public opinion environment, it will cause ridicule."

"Principal Chen, it seems that he is actually self-effacing. I think it may sound a bit proud to say it directly."

Chen Yonggang swallowed subconsciously, and let out a "grunt", this "self-effacing" made him feel very wrong.But I can't explain it in detail.

"So, Ning Zi, although you are confident, I think we should be more cautious. When you say that the chip has been made, do you mean that the chip has actually been produced in the laboratory?"

"correct."

"Then how about this, I'll find some experts to test it first, and make sure there is nothing wrong with it, then let's report to the higher authorities, how about it?"

"Two questions. First, President Chen, do you have a good personal relationship with Huaxia chip experts? If you find them, you can guarantee that they will not talk nonsense? Second, to tell you the truth, I am an expert in this field, and I have already The test has passed. Don’t think too much, just talk to the management that you think is suitable, and they will find someone to verify it. How about this, come to the laboratory to find me after you report, and I will talk to the central security department Say something, and I will let you in later."

"Then... I really told my boss, I'm not kidding."

"Well! Don't worry, Principal Chen, I never like to joke."

……

After hanging up the phone, Chen Yonggang stroked the table, first collected himself, then gritted his teeth, and started looking for someone in the phone's address book.

To be honest, Chen Yonggang, who has been working on chip knowledge for half a month, also thinks this matter is very unscientific, but whether this matter is scientific or not is not up to him, anyway, he is just a mouthpiece.And really speaking, he should cherish this rare opportunity to experience.

Because if time proves that the chip developed by Ning Zi is indeed reliable, then it is estimated that he will not be needed as a microphone in the future.Xiao Ning will have enough channels to directly appeal and report the situation upwards.

So after finding the number, Chen Yonggang didn't dial out in a hurry, but closed his eyes, took three deep breaths, and silently brewed his emotions, then pressed the dial button, when he heard "Hello" from the other side , Chen Yonggang immediately started the performance with the fullest emotion.

"Hey, Liu Si, good news, very good news, under the leadership of our school's outstanding student Ning Zi, with the full cooperation of the school, the chip research and development center of Yanbei Sports University has worked hard for several months and overcome many difficulties. The tireless research and development day and night have finally successfully developed a new chip manufacturing technology recently. This technology is expected to point the way for the rapid development of Huaxia chips in the future and lay a very solid foundation. This is a small step, but it is also a big step in the milestone of Huaxia's chip technology development!"

Chen Yonggang is satisfied with the speech just now.

At least they are very enthusiastic, and the words are very accurate, which not only highlights the individual, but also does not forget the collective...

And yet only got a confused response.

"What? You have developed a chip manufacturing technology? What is the technical principle? Is it silicon material? Where is the innovation? Has the physical chip been produced in the laboratory? Has the packaging been tested? How is the performance?"

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

In fact, we can't blame this Principal Chen for not being professional enough. The main reason is that when Ning Zi informed him of the news, his attitude was too calm, and his words were too brief, and he didn't bother to explain too much to him.And he was indeed too shocked just now, he didn't even think about asking these details, and what was even more annoying was that even if he asked, he didn't know what questions to ask.

After all, which normal principal would understand things like semiconductors.

As long as he can answer one of the above questions... No, it seems that he can answer one.

Therefore, Chen Yonggang immediately started to play: "No, Liu Si, I can't answer you so much. That's right, the physical chip has been produced and tested. As for other things, you may need to come to us in person. The R&D center has done some further research. Well, it’s best to bring relevant experts with you.”

"No, since you've said that, I'm definitely going. But you should make it clear first, what kind of chip is a physical chip? A general-purpose chip? A special-purpose chip? What functions can it achieve?"

"I really don't know about this. Hey, Liu Si, let me tell you the truth. Didn't Ning Zi talk about going to the laboratory of the chip research and development center for retreat a while ago? Then he called me suddenly this morning. His reason It is said that a new heterogeneous [-]D chip that can bypass all foreign patents at this stage has been produced in the laboratory, and the real product has been produced and tested. At least he is satisfied with the test results, so he notified me immediately. As for the other Ning Zi, I didn’t say anything, probably because I didn’t understand it.”

"Yes, Chen Yonggang, you are really comfortable as the principal. Forget it, I won't tell you, I will immediately organize experts to take a look. I will arrive at the University of Physical Education in about an hour."

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

Chen Yonggang was very unconvinced when he heard the busy tone on the phone.

Whoever said that he is comfortable as the principal is really going too far, he obviously has endless worries all day long.

Of course, being unconvinced is just a momentary thing.As a principal, the ability to grasp key points is naturally very strong.It doesn't matter whether he is comfortable as the principal, the important thing is that he will come over in an hour.He had to take a quick look first to feel relieved.

In fact, he planned to report the situation to several leaders.

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

Don't worry about the good news, it's better to wait for the experts to confirm it, and he will call to announce the good news at the first time.

In this way, at least if the leaders ask questions again, he won't be so ignorant.

……

With Chen Yonggang's phone call, countless signals began to be transmitted.Liu Si obviously knew better who he should turn to to listen to the situation report at this time, and knew how true the news was.

It's not that Liu Si has more confidence in Ning Zi than Chen Yonggang. The main reason is that Ning Zi's reputation is there. As the youngest mathematician and computer scientist in China, since he has given this news, he must pay more attention to it. of.

……

The first person to receive the notification was Academician You Wanzhang from the Beijing Institute of Microelectronics of the Huaxia Academy of Sciences.This Academician You can be said to be one of the people who have the deepest research on microelectronics and inherited circuits in Huaxia Official Research Institute. He worked on high-performance chips such as CPU and Flash in many world-class chip companies such as AMD, IBM, and SanDisk 20 years ago. Research and product development work.

Five years ago, because of some unreasonable treatment abroad, You Wanzhang was finally invited by Huaxin International to return to China to take up the position of Chief Technology Officer of Huaxin International at that time.It was only later that he disagreed with the then chairman of Huaxin International 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 issued a series of rules, Academician You naturally became one of the most consulted leaders. During this period, various emergency meetings were attended almost every day.So it was not surprising that You Wanzhang received a call from the real power director of the Science and Technology Department early in the morning.

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

"No, Director Liu, what Chen Yonggang said was a new type of heterogeneous chip that can bypass all foreign patents at this stage? And it's a three-dimensional chip? Is he joking?"

"Oh, Academician You, these are really not President Chen's original words. In his words, they are Ning Zi's original words."

"Ning Zi, I know, the young man is very good, but how long has it been since Apple built the chip R&D center? I only heard about it being officially put into use last month, and I was invited to visit it. But now I have said such a big result , can you really believe it?"

I really can't blame You Wanzhang for asking such a rhetorical question.

In fact, the more people who understand 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 set very high, and the technology moat of the silicon-based semiconductor industry is almost unbreakable.As for the description of heterogeneous, three-dimensional, etc., it is even more difficult.The nature of silicon determines that it is difficult to have a brilliant design at the three-dimensional level, and FinFET gate technology has almost developed it to the extreme.

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

In the era when Moore's Law is about to expire, so many materials institutes around the world hope to find alternative materials for silicon. After all, the atomic radius of silicon is still larger than that of carbon.It also means that at ever-tinier scales, silicon is more susceptible to interference with quantum laws.In fact, on the latest 7NM process level, countless engineers are already racking their brains to overcome various quantum effects on a tiny scale, such as quantum Suichuan.

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

It’s not that these companies will launch heterogeneous material technology immediately. In fact, even if there are new materials and new development directions, these companies will not release this technology immediately, but will use it as an investment in the future, as their own technology accumulation.Wait until the last drop of silicon-based technology has been squeezed out of Lilan before launching it to the public.

However, even though everyone knows that this direction has boundless future and potential, and the research in this area is in full swing, so far, You Wanzhang has never heard of a laboratory that can provide stable and reliable materials for continuous research and development.

Until today, he suddenly heard such unbelievable news from Liu Si. He has been immersed in the research of this field for a long time, so he refuses to believe this news.

"Academician You, if you ask me, I don't dare to believe it. If it is so simple to make a chip, we will not be so caught off guard during this period, and we have meetings every day. But since people notified the news early in the morning , whether it’s true or not, you have to take a look to find out, right? And Ning Zi should know that this kind of thing can’t be joked, maybe there will be unexpected surprises?”

"Then... that's okay. You have to go and have a look first. By the way, there is a very advanced chip testing center in the research and development center of the University of Science and Technology. The instruments in it are very advanced. You can also call the experts from the Semiconductor Institute. Just do the testing and analysis over there." You Wanzhang reluctantly replied.

If it wasn't for the fact that the chip research and development center built by Apple for the University is indeed advanced enough, he really wouldn't be bothered to waste time on this trip.After all, if the news was true enough, he would feel that he had spent most of his life on dogs.

After studying semiconductors for a lifetime, no one can achieve as much results in one month... Not to mention that Ning Zi's most praised achievements are still in mathematics and algorithms.

"Don't worry, Academician You, on your side, from the Semiconductor Institute, and representatives from the company, I plan to form a delegation of six experts to go and have a look. After all, I don't know what's going on now. It’s not good to make too much fanfare, you’re right.”

"Well, six people are enough, but I suggest calling Academician Quan, who is unique in testing."

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

"convenient?"

"Just on the way, I have to pick it up anyway."

"That's fine."

"My side is coming soon, and I will be there in 10 minutes at the latest."

"Ok."

……

Twenty minutes later, You Wanli boarded the special car that came to pick him up.

There are already five experts in the car who I see every day these days.

"Old You, sit here, there is a seat specially reserved for you." It was Quan Maoguo from the Semiconductor Institute who greeted You Wanli, and the two were good friends.

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

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

Apparently several people had discussed it in the car before.

"How can you look at it? It's been more than ten minutes since here, and I'll see with my eyes later." You Wanli glanced at Liu Si, who was sitting in the front co-pilot, and responded casually.

"Academicians, in fact, I don't think you need to be too pessimistic. Maybe there will be surprises 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 lose the mood to continue the discussion.

Whether it is a surprise or a shock is a matter of 10 minutes, and there is really no need to struggle.

But after hearing Liu Si's words, You Wanli knew that the judgments of these people in the car were probably the same as his.

After all, this matter is really unscientific.

……

Soon the car entered the R&D center after inspection.

When Liu Si got out of the car, he saw Chen Yonggang who had come out to greet him.

"welcome……"

"Don't come here for such nonsense, let's be pragmatic today, where is Ning Zi?"

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

"Then go straight in."

"Yes, yes, stop talking nonsense."

A group of academicians in the back echoed, obviously no one wanted to continue greeting Chen Yonggang outside.

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

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

……

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

This time, Chen Yonggang had no choice but to make an introduction, because Ning Zi was in the laboratory, so he could only take a group of experts outside and watch the busy people inside through the spotless glass.

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...
