Hammer of Technology

"some!"

"Great!"

……

In this way, Chen Mingcai was sent out of the laboratory by Ning Wei before he could fully react, and then saw Liu Wei waiting outside the laboratory.

"Xiao Liu, is Dr. Ning always like this?" Chen Mingcai turned his head to look at the closed laboratory door, and asked with infinite emotion.

"What is it like?" Liu Wei didn't realize it. He didn't follow into the laboratory just now. After driving the car to the park, he relaxed a lot. After all, within a radius of about one kilometer, everyone was his own.Although he did not participate in the construction of the laboratory, the safety facilities and layouts that can be seen everywhere in the park, from his professional eyes, can really make it easy to find the flight path of a mosquito, the standard loose outside and tight inside Safe arrangement.

"It's just completely ignorant of the world! Look, it's really cool to play across rivers and demolish bridges. I just took him around the laboratory, and he rushed me out. Is it necessary?" Chen Ming said angrily. .

There is really a feeling of becoming a tool man, which is really uncomfortable.

"This..." Liu Wei hesitated for a moment.

"Tell me the truth!" Chen Mingcai glared at Liu Weiyi, his displeasure palpable in his words.

"Yes! In fact, it's not that Dr. Ning doesn't understand these things. It depends on the person." Liu Wei said very pertinently.

"Oh, look at people!" Chen Mingcai's eyelids twitched.

"Yes, it depends on the person. Dr. Ning's grasp of the world is actually very precise, and he is actually very sensitive when he needs it. For example, he can really take care of his girlfriend's thoughts. But you don't have to feel aggrieved. His people are the ones who feel the most aggrieved." Liu Wei commented.

"Girlfriend! Jiang Chenshuang, right? It seems that the two of them took wedding photos a few days ago?"

"Yes!"

"Ningwei attaches great importance to it?"

"Yes!"

"Okay, I get it. You'd better go in and keep an eye on it. Some of the equipment inside is dangerous because of the engineer's improper operation. I'll go first. Oh, by the way, remember to notify me when he is leaving. Forget it Now, take him directly to my temporary office here, which is in Room 2, Building A307."

"Yes! Guaranteed to complete the mission."

"Okay, don't be so formal, remember to call me Mr. Chen."

"Yes, Director Chen!"

……

Liu Wei walked into the laboratory, closed the door again, and saw that Ning Wei had already put on a white coat and was sitting busy at the operating table in the laboratory on the first floor.

Well, it doesn't really look dangerous, except that the figure of the whole person looks a little lonely.

Liu Wei thought for a moment, stood in front of the laboratory door, carefully read the regulations and rules for entering the laboratory on the notice board hanging at the door, then went to the changing room to wash her hands, and put on a white coat. Just walked into the laboratory.

Naturally, Liu Wei would not touch those seemingly inconvenient devices. He stood directly behind Ning Wei as usual, watching Ning Wei typing on the keyboard quickly on the computer on the console. .

"Brother Liu, come in."

"Well, I thought you didn't notice me."

"I can do two things at once. I knew when you entered the laboratory just now, but anyway, you are one of your own, so you don't need to call me, right?"

"Hmm! Mr. Ning, are you here?"

"Write a standard interface program according to their system. You can understand it as a translator. I saw in the laboratory that many of them are actually automated equipment, and the data collection work is directly summarized to the workbench, without manual recording. What we need to do now is to enable March to quickly understand these data, but different devices come from different manufacturers, platforms are different, and data records are also different, so we must first unify the standard.”

"There should be a ready-made template for this?"

"Yes! Of course there is! Otherwise, the engineers at Huawei will not be exhausted. But this laboratory is different. Isn't this directly connected to our supercomputing center? It doesn't need to be so complicated. I actually just use a ready-made interface program , but a slight modification can improve efficiency.”

Liu Wei didn't say a word. When it comes to such a very professional topic, he can't get in too much, but he understands the truth that if you want to do a good job, you must first sharpen your tools.This is like wanting to win a battle, it is still very important to have cutting-edge weapons.The principles of being poor enough to intersperse with tactics, rich in firepower, and handing over what should be done to equipment are actually the same.

"OK! It's done! Now we're going to test these instruments. It's just that you come to help me conduct a preliminary test on these instruments!" After 5 minutes, Ning Wei clapped his hands and stood up from the console.

"This, I don't quite understand!" Liu Wei was a little embarrassed.

He understands the value of these machines. Although he can't name them, he has probably browsed through Ningwei's proposals. In short, the cheapest thing in the laboratory that is similar to a microscope costs hundreds of thousands, and those For a relatively large system, the cost of a set is directly eight figures. He is afraid that if it is broken, he will not be able to pay for it if he sells it.

"You don't need to understand. It's basically a matter of pressing a button. You definitely don't want to take it apart and refit it." Ning Wei said without raising his head.

"Do you want to dismantle and modify it?" Liu Wei was shocked.

It is said that these gadgets are of high precision, and they are sealed tightly. He doubts whether they can be restored if they are really taken apart.

"It's so fresh, it's useless if you don't change it, and it's not as difficult as you imagined. As long as you understand the principle, it's not difficult to have debugging equipment. But the debugging equipment is not in place yet, and we won't disassemble it for the time being. Okay. These properties are enough now. The main function of this laboratory is to test whether the material properties meet the requirements at various scales. The data in this piece is very important, and the data model is established for the most important steps in production. You can look at it first. Instructions, I will connect the system later, you go to turn on the devices one by one, and I will see if the data structure here is correct."

"OK then!"

Really, Liu Wei would never have imagined that he would wear a white coat as a laboratory assistant one day even if he was killed.Of course, this is not really a good memory. It is probably because Ning Wei ordered him to press various buttons. His cautious temperament made him have to confirm with Ning Wei twice before operating it, and even attracted Ning Wei's praise. , saying that he has the rigorous attitude necessary for scientific research...

Well, Liu Wei had an illusion that maybe if he had taken another path back then, he might have become a qualified man of science and engineering.Of course, Liu Wei is not sure whether this is really the case, because he doubts that Ning Wei has the ability to make everything easier.

In this way, he was busy downstairs for a long time. At noon, he took Ning Wei to the cafeteria of the park for a meal, and in the afternoon, he went to the supercomputing center. Unfortunately, Yu Xingwei was not there, and Ning Wei's most important assistant returned to Jiangxi for the time being. Da submitted the thesis and prepared to defend the thesis. He would not be able to return until March, so he was busy with Ning Wei in another laboratory in the afternoon.

But when he reached the second floor, Ning Wei didn't let Liu Wei enter the clean room, but asked Liu Wei to help him put on the bulky matching dust-proof clothing.Really, the whole process was so cumbersome that Liu Wei felt a little unbelievable.According to the instructions posted in the changing room, not only can you not bring anything with you, but you must also use special soap to remove makeup before entering the clean room. You must drink a glass of water to rinse the particles that may exist in your throat, and then wear a mask to cover All facial hair.

Next, I have to tidy up my hair, put on a dust mask, then clean the shoe body, put on shoe covers, and put on special boots after doing this.And completing these is only the first step.The next step is to go to the main changing room next door, which is also an airlock.

Liu Wei cannot enter this room, but Ning Wei still assigned him a task, which is to inform Ning Wei of the next dressing steps through a microphone outside, and observe whether Ning Wei does each step through the glass. If it is in place, if it is not in place, it must be reminded.Of course, the former is not necessary, but the latter is still necessary.

So next, Liu Wei understood the whole process of changing this dustproof suit.First of all, put on long nylon gloves, and then put on the dustproof clothing. In this piece, you must also pay attention not to let the clothes touch the ground. You must stuff all the trousers into the boots and fasten the buttons on the boots.Next, put on the filter device after dressing neatly. The filter device should be inserted into the battery pack and fixed on the belt together, and then put on the safety helmet.The edge of the hard hat should be tucked into the dustproof overalls, and the hose of the hard hat should be connected to the filter device, and then the knob should be tightened.

Next, put on safety glasses, install a disposable protective cover on the hard hat, and buckle the hard hat, and finally put on a rubber glove, and the whole set of equipment is put on the body.Liu Wei checked the time, and the whole changing process took about 10 minutes.How should I put it, just from changing this suit, Liu Wei felt the difficulty of doing scientific research.

What followed was a long wait. The clean room was not made of transparent glass, so Liu Wei had no way to directly see Ning Wei inside.Fortunately, after studying the description of the entire clean system, Liu Wei knew that there is also an embedded camera in the clean operation room. Unlike ordinary cameras, this completely flat camera with no sanitary corners is an integrated design with the internal dust monitoring , so through the monitoring room next to him, he could see what Ning Wei was doing in the operating room.

All the cameras in the clean room are designed as a flat panel, so the viewing angle is not as flexible as that of ordinary cameras.But you can probably see Ningwei's movement patterns, basically walking around the equipment, and then leaning down to check.Among them, he stayed at the robotic arm installed around the laboratory for the longest time, and would go to the clean room console from time to time to make some records.

Well, the whole process is actually quite boring.Because from the perspective of observation, I don’t actually know what the people in the camera are doing. I only know that Ningwei officially activated the large-scale equipment in the operation room after being busy for about two hours, and the mechanical arm also started to move. It just doesn't seem to be performing a task, but doing some seemingly dexterous movements, probably still testing.

During the period, Ning Wei's cell phone rang twice. The first time was from Tian Yanzhen. Liu Wei thought about it, but he didn't answer it. The second time was from classmate Jiang, and Liu Wei connected without hesitation. Yes, and then told classmate Jiang that Ning Wei was carrying out an important scientific research task, and it was not convenient to answer the phone for the time being. He would inform Ning Wei to call her back as soon as possible after finishing the work at hand.

Based on his understanding of Ning Wei, Director Tian didn't answer the phone call, so he didn't answer it, and he made a phone call later to explain and it was over.But if classmate Jiang didn't answer the phone, Hui Ningwei might scold him when he comes out of the clean room.

In short, he didn't know what Ning Wei was busy with in the operating room. He only saw the time passing by, and it was almost [-] pm, and he still didn't know what he was busy in front of the operating table in the clean room.

Finally, even Chen Mingcai called.

"Xiao Liu, are you still in the lab?"

"Yes, Mr. Chen, Dr. Ning is still in the clean room. He went in in the afternoon and is still busy."

"Oh! Then how long do you think he will be busy? Can you come out before eight o'clock?"

"I don't know! It's not easy to disturb. From the monitoring room, he is very focused now."

"That's it! Do you want me to find someone to bring you dinner?"

"No need, Mr. Chen! I'd better wait for Dr. Ning to come out."

"Okay, then you don't need to bring Dr. Ning here today. Let's see if he will come tomorrow. If not, I will bring the contract to him tomorrow."

"Okay! Director Chen!"

Here Liu Wei put down the phone, the monitor Lin Ningwei finally walked away from the console, and then walked towards the exit.

"Huh..." Liu Wei let out a long breath and finally came out.

To be honest, at this time Liu Wei really admired Ning Wei, who could stay in the operating room alone for more than five hours wearing such an airtight suit.This is probably the resilience of scientific researchers, right?

……

However, as soon as Ning Wei left the laboratory, he began to complain in the changing room: "I'm going, let me tell you, brother Liu, this thing is not only troublesome to wear, but also cumbersome! Really, I just wanted to be in it Just take off this suit and go to work."

"Director Tian called classmate Jiang just now, but I didn't answer Director Tian's call. I told classmate Jiang that you are doing an important experiment and it is not convenient to answer the phone." Liu Wei ignored Ning Wei's complaints and reported. .

"Oh, okay, I have to call Chenshuang back and tell her that I won't be going back tonight."

"Not going back?"

"Yes, I'm not going back! We'll stay here all night tonight! We've gone through the digital three-dimensional channel circuit design and arrangement many times in March, and now we have all the necessary instruments in place, so we have to try it out. We'll stay here all night tonight. In the lab, let's see if we are lucky and can rub a chip out of it."

Ning Wei rubbed his hands excitedly and said.

"Rub the chip with your hands?" This sentence really shocked Liu Wei.

What is this for?What about trouble?The laboratory was only handed over to you today, and the contract is still signed. If you rubbed a chip with your hands all night, do the group of people still have to live?Especially the bosses who opposed the construction of this laboratory at the beginning.

Although he doesn't have much information at this level, the budget given by Guang Ningwei has already made many people want to oppose it. It is impossible to complete the renovation of one of the buildings so efficiently in one holiday.

But these are already in the past tense, and there is no point in discussing them. He just hesitated and asked: "The chip you are talking about is something like a mobile phone or a computer CPU? The performance is better than Intel?"

Ning Wei rolled his eyes at the very layman's question: "I want to eat farts! If the chip produced by this device can be more powerful than Intel's decades of technology accumulation, let alone one trillion in five years, I will be able to do it in one year." Believe it or not, you can make trillions? Test, test, understand?"

"And this test is not a cpu, but a three-dimensional silicon-carbon combined radio frequency chip, which can cover radio frequency applications from the l-band to the microwave and millimeter wave, 3g, 4g, wifi, 802.11ad and wigig frequency bands according to the original design intention. If you want Converted from the technological level, Intel is said to have mastered the 3nm manufacturing process technology, and the thing we rubbed out, if calculated, is probably 180nm process.”

"180nm?" Liu Wei felt a little low. Although he didn't know much about technology, he could still calculate how many times the difference between the 180nm process and the 3nm process was, and the difference was like 60 times.

"Look down on our chip, don't you? New materials and new technology, let me describe it to you this way, let carbon nanotubes grow in TSVs that are 333 times thinner than a hair according to a pre-designed circuit, like this There can be tens of thousands or even hundreds of thousands of TSVs in the future, and they must also be arranged together according to the design plan. In each TSV, there are hundreds of thousands or even hundreds of thousands of carbon transistors responsible for various units in the future. Wan, take your time."

"The 3nm process integrates 2.5 million transistors per square millimeter, but they are concentrated on one plane. We are different. In the future, we will count the number of transistors in cubic millimeters. How do these numbers add up? Not only that, but also New packaging process, did you see the machines controlled by the robotic arm around the inside? Those are all packaging equipment for the entire process, a complete set!"

"Let me tell you this, don't think that other people's 3nm technology is better than ours, but if we can really rub out this chip today, the various test results can meet the standards, and the heat dissipation of the chip is not a major problem, then the finished product will be mailed to the United States. Go and take a look at the big boss of Intel, maybe he will fly to China immediately, and the first time he sees me, he will kowtow and call me daddy, don't you believe it?"

In fact, Liu Wei really wanted to say that he didn't believe it, but seeing Ning Wei's excitement, he chose to shut up.

Fortunately, Ning Wei didn't bother with him at all, and picked up the phone directly. As he expected, he didn't call Director Tian first, but directly called Classmate Jiang.

"Hey, I have an important task tonight, so I won't go back. You can tell my parents. ... Well, well, don't worry, the automation process is mainly because I have to keep an eye on it. When I have nothing to do at night, I must I will sleep.... Well, tell them not to worry, the family is in your hands... Tell you, don't miss me so much..."

Seeing Ning Wei having a happy chat on the phone, Liu Wei silently took out her phone, walked to the other end of the corridor, and dialed Chen Dong's number.

"Dr. Ning said that he will stay in the laboratory tonight. Yes, it is best to send two beds... He said he wants to rub a chip with his hands. If it succeeds, it will be the world's leading one... Well, good!"

------------

276 Tell everyone what is the real industrial revolution

Although from the bottom of my heart, I don't really believe that the laboratory can be produced in Ning Wei's hands for a day, and the boss of Intel can see the high-tech products that are about to fly to China in a hurry, but when it really comes time to experience it, Liu Wei's heart is still full of anticipation.

To put it bluntly, he willingly gave up his good life to stay by Ning Wei's side, guarding this young man's fragile and precious life day and night, waiting for this moment.The only thing I didn't expect was that the time was surprisingly fast.

But when he patiently accompanied Ning Wei to finish dinner, and then found an empty room in the laboratory to set up a bed, put on brand new green sheets and quilts, and when he found Ning Wei, he saw this old man. The scientist is staring at the operating table in the laboratory on the first floor.

Walking into the laboratory, looking at the series of numbers on the console monitor that gave him a headache just looking at them, Liu Wei couldn't help asking: "Dr. Ning, when do you start rubbing chips by hand at night?"

"Huh? Didn't it start a long time ago? What do you think I was busy here between the time we finished the phone call and before eating? I was supplying materials and debugging equipment. Did you see the data? ? Now I’m waiting for the test report, and then compare it with the data model I ran before. Wait, you won’t tell me that you rub the chip by hand, but you really rub the chip out by hand?” Ning Wei twisted He turned his head and looked at Liu Weiyi with a very surprised look.

To be honest, this look is really hurtful.Even as calm as Liu Wei, she couldn't help but blush, and explained: "Of course I didn't mean that. How could it be possible to rub out the chip with your hands?"

Ning Wei simply looked away and explained: "That's good, otherwise I will doubt your ability to understand! Take a look, which equipment in this laboratory is not automated? Including the clean room upstairs, in fact Most of the work can be done automatically by machines, which is why I want to build a new laboratory. In fact, it cannot be said that the equipment in the school laboratory is completely unusable, but in terms of automation, it is not as convenient as building a laboratory by yourself ?”

"Especially when it comes to multi-person operations, let me tell you that if these devices are used well, they are extremely efficient, and if they are not used properly, they can kill people. Don't think that you can help me debug these devices today because you know everything. To meet that kind of frizzy guy, close your eyes and give you a blind eye, it may take a week, longer or even the risk of not being repaired."

Liu Wei was a little surprised, pointed to the monitor that Ning Wei was facing, and said, "So what you mean by rubbing the chip by hand is to watch these instruments automatically complete the chip? Doesn't manual participation need to be involved?"

Ning Wei explained with a smile: "Haha, how could it be possible not to participate. Of course, full automation is also possible, but this laboratory has not yet reached this condition. And if you don't participate at all, why should I stay here overnight? The bed at home is not as good as Is it comfortable here? But then again, although there is no need for manual labor, the level of automation is already quite high. Most of the time, we don’t need to do anything manually, we just watch.”

Well, just watch it.

Liu Wei probably understood that the so-called rubbing chips by hand was actually two people sitting dryly, waiting for the lab to get the chips out, and couldn't help sighing: "Then this is too simple, right?"

"Simple?"

Ning Wei glanced at Liu Wei, and said, "Brother Liu, you are explaining to me what ignorance means to be fearless! You don't really think that you can make a world leader out of thin air by buying equipment? You know our field How many people did the director beg with that old face in order to let other laboratories open the data to us? How much did I spend on electricity to integrate these data? And how tired is my three-month-old kitten recently? "

Liu Wei doesn't know how to answer, especially is March very tired?At least on the day of the New Year's Eve dinner, he looked relaxed in March...

After a series of rhetorical questions, Ning Weicai said earnestly: "So, brother Liu, don't think it's easy. We just leave the hard work to the usual, without the March smart platform, without the efforts of many people , Let alone one night, even a year may not be able to get it out. This is like some academic masters when they were studying. You can see that he usually plays, but every time he takes the exam, he is in the top few. He studied People didn’t notice it at the time. Of course, this is not the same as my situation. Although I don’t work hard at ordinary times, my grades have always been pretty good. This is probably talent.”

In fact, without adding the last sentence, Liu Wei wanted to give Ning Wei and those people in his mouth a compliment.But after adding the last sentence, the smell changed, making Liu Wei not want to say anything.Not everyone loves to read, and not everyone has fond memories of reading.

A top student may not be brighter than a bad student. For example, like Ning Wei, many times his whole body exudes an unpleasant atmosphere. For example, at this time, a sentence made the originally good chat atmosphere not so refreshing.

Fortunately, the two of them are actually not chatty. When Liu Wei found out that he couldn't help him all night, he sat quietly next to Ning Wei. Since he didn't need him to do anything, he should be himself. My job is fine, it's just a little boring, but just the two of us can play with our mobile phones, and the time will pass by.

As for Ning Wei naturally staring at his screen, God knows what's so interesting about refreshing the extremely fast data from time to time.Liu Wei would occasionally look up and glance at Ning Wei, who was staring at the screen thoughtfully.Heh, it's fake to not work hard behind the scenes. Is such concentration just a faux pas?Obviously IQ is already very high, but I'm afraid that others will show off at any time without knowing it, and I don't know who is influenced by it...

After staying with Ning Wei until twelve o'clock, Liu Wei went out to check.In fact, there is nothing to worry about in terms of safety. The main thing is to make sure that his partners are all on the job. The cautious temperament has almost been engraved in Liu Wei's bone marrow.As he told Ning Wei before, his mission never tolerated any mistakes.

When he came back, he found that Ning Wei had left the laboratory on the first floor, so he hurried up to the second floor, and found that Ning Wei had already started to put on the dust-proof equipment by himself, and was about to enter the clean room again.

The second time he wore this set of clothes, Ning Wei was obviously more proficient. He didn't need him to remind him of the steps step by step. He put on a set of equipment in about 10 minutes at most, and then walked into the operating room.

There is nothing to say, in Liu Wei's view, the machine started, the mechanical arm also moved, and the computer on the console turned on and off, and then on again.But this time Liu Wei didn't have to wait long, only half an hour at most, and Ning Wei walked out of the dust-free operation room.

"Ahem, did you succeed?" Liu Wei couldn't hold back again and asked.

This question once again brought Ning Wei a surprised look,

"Brother Liu, you seem to be more excited than usual tonight? By the way, you didn't seem to care much about my research before? Tonight is a bit unusual." Ning Wei looked at Liu Wei and said.
