Chapter 217 Regarding this issue, I am here to tell you: Yes, EUV has been successfully launched!
"Teacher, what are the arrangements?"
In a wafer factory in southern China, Zhou Xiaochen and his student Li Kun are busy working.
"At the industry summit, our company is preparing to take on a cooperative project with Baiju Technology." Zhou Xiaochen said, "We will conduct a series of program evaluations in the next few days."
"What's the plan? Is it about the photolithography machine?"
"No, for carbon-silicon fusion semiconductors, photolithography should be a small part, and the majority should be the placement of carbon nanotubes based on semiconductor silicon. The ultimate goal is to generate high-purity, high-density single-arm carbon nanotubes on a wafer basis."
Zhou Xiaochen said: "Recently, you need to change your study direction and pay more attention to the growth of carbon nanotubes by chemical vapor deposition (CVD), especially the public papers and materials related to how to control the growth position through base patterning. You must pay more attention to this topic."
"Isn't this too difficult?"
The single-arm carbon nanotube is not a new concept. Moreover, after Baiju Technology mentioned carbon-silicon fusion semiconductors at the press conference, almost everyone in the industry reconsidered the feasibility of this thing.
Although there are relevant theories now, at present, we can only use semiconductors as the main body and carbon nanotubes to assist in connecting multi-layer chips, but we cannot achieve high density, let alone the specific growth of three-dimensional high-density carbon nanotubes in wafer semiconductors.
"Difficult? Then do you think it's difficult for us to develop EUV lithography machines?" Zhou Xiaochen asked: "We must seize the opportunity!"
At this industry summit, Baiju Technology unveiled their Class B cooperation projects.
Among them, the two most important contents are the three-dimensional five-sense communication network and the upstream and downstream of the carbon-silicon fusion semiconductor manufacturing line.
The relevant research on carbon-silicon fusion semiconductors has been confirmed to be a joint research by Huawei, Shanghai Microelectronics, and Baiju Technology.
Zhou Xiaochen is a young and vigorous person in Shanghai's microelectronics equipment industry and a system microenvironment engineer.
Currently, his main job is the modeling, simulation and analysis of complex micro-environment subsystems in lithography machines and wafer production lines.
The microenvironment system involves many disciplines such as mechanics, thermal engineering, environmental engineering, architectural environment and equipment, mechanical design and automation, control engineering, electromechanical engineering, and information engineering. It is also an integrated system engineering.
How complex is this system?
Let me put it this way: my country's lithography machines, especially EUV lithography machines, have been delayed in mass production again and again. 30% of the reasons are due to some sophisticated components, such as the light source system, objective lens system, etc., but at least half of the reasons are due to problems with the microenvironment system.
In other words, the same parts, or even the same machine, if assembled and maintained by different people in different places, can produce completely different results.
A slight error can lead to a huge mistake, which is the truest portrayal of precision manufacturing.
Take chip manufacturing as an example. Sometimes a temperature difference of 0.1 degrees Celsius may lead to a 20% drop in yield.
But how to discover such subtle problems? How to solve them? Integrate micro-environment modeling from many disciplines, and then feed back to the production system for fitting and adjustment.
However, Zhou Xiaochen is not outstanding in the field of EUV lithography machines and wafer production lines.
Not to mention the whole world, the world's best chip industry microenvironment engineers are definitely in ASML and TSMC. Even in China, they are only in the second tier.
Is this difficult?
Not difficult? Shanghai Microelectronics has been working on this for at least five years, and until a few months ago, the progress was still very worrying.
Disaster?
Looking at the current production data parameters, Zhou Xiaochen couldn't say this - currently, the yield of this production line equivalent to TSMC's N4P process technology has reached 75%. Just two days ago, the team was still evaluating trying the next process node.
For N4P, the actual wafer density certainly cannot reach 4nm. Now everyone is discussing it in terms of equivalence. The southern factory also uses the same standard as TSMC to facilitate relevant comparisons.
The N4P process was announced by TSMC in October 21, but as of January 10, three and a half years have passed, and its current yield is still only around 24%.
With the help of Xiaosha, Zhou Xiaochen achieved this result in just one month.
What does this mean? It is obvious when compared with another company. Samsung spent a full year debugging the same process from 25% yield to 60%.
"So, Li Kun, do you understand? It doesn't matter whether it's difficult or not. As long as we have a direction, and with Xiaosha, we can break through step by step, and sooner or later all the problems will be solved."
Zhou Xiaochen smiled and said, "This is also the unique advantage of digital clones and external memory."
Li Kun knew that the teacher was trying to change his mind on the basis of solving the problem.
Baiju Technology’s digital clone service has been launched for nearly a month. Until now, many people still don’t understand: Why not just store all the knowledge in the world in my digital clone with external memory?
Li Kun also thought so at first. Zhou Xiaochen told him at that time: With the help of Xiaosha, I can quickly achieve mass production of EUV N4 or even N3 level, but you can't.
——If you originally knew something but have forgotten it, then the external memory can help you recall it. However, if you originally didn’t know it, it’s useless to put it in.
Regarding this issue, the two had a heated argument on the day the digital clone was released.
At that time, Li Kun didn't quite understand it, but after experiencing so many days and experiencing the earth-shaking changes that take place every day in the wafer production line of EUV lithography machines, he finally had the most essential understanding of this thing - the strong will always be strong!
His teacher could use Xiaosha to get N4P in just one month. He could also use Xiaosha, but at most he could only get 14.
"This is the synchronization of data and people," Zhou Xiaochen admired this seemingly unrelated but actually comprehensive mapping concept: "Okay, starting tomorrow, we will enter the next stage of work.
"Later, according to the work arrangement, we will debug the carbon silicon semiconductor equipment, but this will probably take some time."
Li Kun nodded to show that he understood. The micro-environment system and related debugging work were the last ones to be completed, and the next stage node debugging was the recent work arrangement.
The next node is TSMC's equivalent of 3nm. The expected parameters here are directly benchmarked against N3P, and the estimated adjustment cycle is 45 days.
Zhou Xiaochen has already prepared the data and materials needed for the next stage, while Li Kun is considering another question: "Is the new carbon-silicon semiconductor fusion my chance? I'm still not strong enough!"
Li Kun has never been an honest person. At this time, he was still thinking about sharing digital clones.
If this problem is solved, then don't I have to learn knowledge and accumulate experience day by day?
"There is a mapping relationship between my digital avatar and me, and there is a mapping relationship between the teacher's digital avatar and the teacher. Both digital avatars are actually binary data. I can't use the teacher's data directly because I don't understand it. But is there a way to do a conversion?"
At the beginning, Li Kun didn’t understand the meaning and mystery of the digital clone at all, so he didn’t think about similar questions.
but now……
He shook his head. This wouldn't work. Even if he could convert it into the same "format" as his digital clone, he still wouldn't be able to directly understand things he didn't understand.
However, will this make it easier for you to learn and understand, and then more quickly master the content and knowledge that you didn’t originally understand?
"Xiaosha, Xiaosha, is this okay?"...
In Linzhou, the off-site press conference of the chip industry summit is already underway.
Hao Cheng first introduced the situation of the summit and announced the Class B cooperation topics and the corresponding list of partners.
"Mr. Hao, I have a question. I have just been listening to you talking about the follow-up research and development and cooperation projects of the new carbon silicon semiconductor chip. There is a question that everyone is very concerned about, that is, what are the advantages of such a chip compared to traditional chips?
"We know that Xiaosha's capabilities are already very strong. In fact, many people think that it has no room for improvement. So, this chip will bring Xiaosha better growth, and even let us fantasize. Many people don't know where to think. Mr. Hao, can you help me answer this question?"
"I won't answer this question. I'll let Xiaosha answer it." Hao Cheng introduced the situation and said, "The Xiaosha I use is higher than the public version. It's an internal test version. You can understand the difference after listening to it. Xiaosha, please."
[Okay, let me give you an example.]
What Xiaosha happened to talk about was the problem that Li Kun encountered. However, he was not the first nor the last person to ask Xiaosha this question.
Xiaosha introduced the situation and then continued:
[Have any of you ever had the fantasy of taking someone else's digital avatar and using it for yourself? If so, please raise your hand! ]
About one-third of the people in the room raised their hands. They had indeed thought about it, even if only for a moment.
And one third of the people had clear eyes and were a little surprised in their hearts: Is this possible?
As for the other third, although I had never thought about it before, after listening to Xiaosha's words, I immediately realized: How could it be possible?
[Is this possible? Of course not! If you can use someone else's digital avatar, then can all the knowledge on the Internet be put into your external memory?
[Of course you can't do that if you don't understand it. Each of us has different ways of thinking, understanding, and thinking abilities, and the data in external memory is definitely not universal.
[Some people may have doubts, what's the point of saying it here if it's not universal! I said it's not allowed now! ]
"Will it be possible in the future?" At this time, everyone was immersed in Xiaosha's rhythm and even forgot that it was a robot.
"This Xiaosha is obviously smarter than the one on my phone. Is this the beta version of Xiaosha?" Hao Cheng often uses this version of Xiaosha in internal meetings, but this is the first time it has been live-streamed on the public Internet.
"The present of Xiaobu Xiaosha is not important at all. What is important is what does it mean by this sentence? Is it really possible in the future? Wouldn't that be equivalent to enlightenment?"
Not only the netizens who watched the live broadcast, but also the reporters and audiences at the scene had the same doubts, and some even shouted the word "initiation"!
But why does “initiation” sound so much like a plot from a fantasy novel? It doesn’t even exist in science fiction, right?
[Will it be possible in the future? My answer is: Of course! But please note that this is not for direct use. Let me give you an example. Have you ever seen an onion? It is the round one that can be peeled off layer by layer!
[If knowledge can be measured by the volume of an onion, a whole onion would be all the knowledge in your field in modern society. Then, your current level of knowledge would be the core of an onion, the tiny dot at the very inside. If you pinch it, it will be gone!]
Xiaosha's words surprised not only the audience and reporters, but even Hao Chengdu. It was a good thing that Xiaosha didn't have real fingers, otherwise he would have made a "pinch" gesture to you!
However, although he did not demonstrate it, everyone had already imagined the image of such a gesture in their minds.
"Xiaosha is so cute. But, you overestimate me. If all knowledge is just the size of an onion, then there is no way I can be as big as an onion core. According to the proportion, there are probably so many epithelial tissue membranes in the onion core that you can probably see it under a microscope." Someone also replied jokingly in the live broadcast room.
[Let’s not talk about whether you are that big or not, but let’s say you want to learn and master more knowledge. If I throw the whole onion to you, you will definitely not be able to learn it, right? Because the further you go, the more complicated, cutting-edge, and difficult it is.
[This is also the reason why it is meaningless to store all your teacher's or even the world's knowledge directly in your external memory or digital clone.]
At this point, some people already knew what Xiaosha wanted to express. Someone even described it directly: "You want to learn from the inside out, right? I am the core of the onion, so what I can accept is the layer that is attached to the outside of the onion core."
[Yes, if the entire onion of the world's knowledge, or half of your mentor's onion, is thrown to you and you can't handle it, then we will decompose this thing and only add a thin layer to your digital clone.
[Then, at this time, is it much easier for you to learn? Even those with high IQ and strong learning ability can use it right away! Because your external memory is the most suitable for you. ]
Unlike the initial press conference, people now have a certain understanding of the concepts of digital clones and external memory, and know that external memory is tailored to their own behavioral habits, thinking patterns, and thinking abilities.
Also, this thing is different for everyone.
In this case, if you can wrap the external knowledge like an onion and add a layer according to your own characteristics, you will definitely be able to learn, understand and master it quickly.
[On the surface it looks like peeling an onion, but the actual essence of this matter is to design a way of learning that suits each person.
[However, there is one thing that Xiaosha cannot do now. ]
"Ah? Can't do it? You said you can't do it for so long!"
"Yeah, are you trying to trick us?"
"What's going on?"
Many people were confused by this ups and downs. Is Xiaosha playing tricks on people like this? Has he become a spirit? Many people on the Internet are indignant. Even if you are smart, you can't fool us!
[So, this is the meaning of the continued progress of chips, and the meaning of Xiaosha's continued progress! This is the lady's question. Are you satisfied with my answer? ]
"Fuck! It's like a spirit!" Many people then realized that Xiaosha was here to answer a question just asked by a reporter. This answer was simply amazing!
"Do you want my version of Xiaosha?" Hao Cheng took over the conversation, and a group of people responded one after another: "Yes!"
“However, unfortunately, it cannot be supplied on a large scale now because it consumes too much computing power. This is also the significance of future chip progress.”
Hao Cheng said: "Xiaosha's answer just now revealed something that was not originally planned to be mentioned at today's press conference, but since Xiaosha has mentioned it, let me inform everyone:
"The essence of digital clones and memory knowledge sharing is to break down knowledge into pieces and layers that are suitable for each person. It's like breaking it up for you to understand.
"The full version of this function requires the mass production of carbon-silicon fusion semiconductor chips. However, the basic version will first be OTA-ed on the children's robot version to help every student learn."
Speaking of children's robots, the unlimited pre-sale of the CPU-free version started at 1.2 noon today. As of now, the total number of pre-orders has reached 1.5 million. Together with the previous million, the total sales of Xiaosha robots have almost reached million units.
This almost covers the total number of children in the compulsory education stage in the country.
Of course, since the age limit has been relaxed, a large portion of these products are purchased by "older children".
1.5 million units. Many people don’t know how to evaluate this number, but some people think that this number is too small. After all, there are 1.6 million students in elementary and junior high schools combined. But, you know, this is just one day!
"Okay, let's get back to the topic today. Our topic today is chips. The man in the red down jacket in the middle of the second row, please tell us your question."
"Hello, Mr. Hao. We have just been talking about new chips of the future and Xiaosha's progress. I actually want to ask a question: What about our current chips? What will happen in the future?
"As for the EUV lithography machine, I saw some media reports saying that it has been able to meet mass production standards. Is this true?"
"You asked a very good question. Just a few hours ago, many people in our industry also had the same doubt."
Hao Cheng explained, then briefly summarized what he had said at the meeting, and finally said: "My speech at the opening ceremony of the summit today will be compiled into a complete version on the official website later. If you are interested, you can take a look.
"As for your second question, I am here to tell you on behalf of our partners, Shanghai Microelectronics and Huawei:
"Yes, all four EUV lithography verification machines have completed mass production at least equivalent to N4P, and mass production machines are also being shipped out of the factory one after another!"
