Future super intelligent system

Chapter 115 Theory of New Materials

"What material?" He Tingbo asked subconsciously.

"Graphene."

Hearing Liu Fan's answer, everyone's expressions changed in different ways.It has been mentioned for many years that graphene will become the future chip material, and this is the most mainstream view now.

If you search on the Internet, you can see that graphene is the most likely to become the chip material of the future. In particular, its advantages are very obvious. It is called the lightest and thinnest, the highest strength, the best toughness, the best electrical conductor and the best thermal conductor. The material with the highest light transmittance.

From 2014 to now, IBM has invested 30 billion in graphene chips. However, it is because of so many years of global research on graphene chips that people have gradually discovered that graphene does not seem to be so suitable for use. to make chips.

First of all, graphene also has many defects of its own, such as no energy gap, and the excellent mechanical, chemical and electrical properties of graphene are not what chips need most. Many people say these when they mention graphene chips. advantages, regardless of the significance of these advantages.The bottleneck encountered in the current chip development is composed of many problems, such as difficulty in increasing the main frequency, chip power consumption and bandwidth obstacles, etc., which cannot be solved simply by changing the material to graphene.

There will be a problem. The graphene chip technology is still very backward, and the yield rate problem is very serious. Enterprises spend so much money to design and produce graphene chips. As a result, many problems are still unsolved, and the chip performance is still not up to expectations. , It was useless after a long time.

Although many of you sitting at Kunxin Technology are entrepreneurs who do not understand technology, graphene has been popular for so many years, and they are more or less aware of the plight of graphene chips, so when Liu Fan said that he found a new When the material is graphene, everyone is a little disappointed.

But this basic disappointment is fleeting, because the person in front of him is Liu Fan, a guy who specializes in miracles.

Sensitive Liu Fan naturally captured everyone's emotions, and said with a smile, "I know what everyone is thinking, but I have a method of combining graphene with traditional silicon materials, which can obtain very ideal results."

Liu Fan said, and opened the PPT, "This is the whole design principle."

"It's very similar to the principle of the graphene 3D chip of Max Shulaker's team." Ji Mushui glanced at it and said subconsciously.

"It's indeed a bit similar." Liu Fan nodded. He has spent a lot of time researching architecture and materials recently, so he has some knowledge of Max Shulaker's team at the Massachusetts Institute of Technology. "But if you look carefully, My design principles are fundamentally different from theirs.

The difference is that their designs are based on traditional silicon materials and supplemented by graphene, while in my design, graphene is mainly used and traditional silicon materials are supplemented. "

Liu Fan flipped through the PPT, "Graphene 3D technology is now very mature. In my entire design concept, the greatest significance of graphene is to realize the complex folding of materials and improve the sensitivity of transistors to light. And I used a very simple The double-spoke symmetric structure and the use of the comb structure allow the silicon material to have a self-regulating space in the graphene material, and this space can greatly solve the problem of energy consumption."

With Liu Fan's more and more detailed introduction, everyone has a clear understanding of the application of this brand new graphene material.

But if this kind of material is really usable, then Liu Fan's living water structure is likely to follow, and at this time there will be some urgent problems to be solved. For example, Wang Tao couldn't help asking, "If we can have our own Architecture is certainly a good thing, but how to solve system problems? It is absolutely impossible for the win system to be opened to us.”

Liu Fan looked at Wang Tao, and suddenly raised his eyebrows a little angrily, "Don't you Huawei have your own system, and you used the system to piss off Lao Mi a while ago."

Wang Tao smiled helplessly, "Isn't it worried that they are shameless to the extreme? Now using our autonomous system is just the last move when there is no other way. Huawei still can't solve the ecological problem, and solving this problem requires The time and effort required was greater than we anticipated.”

"Did you forget about Wood Dragon Technology?" Liu Fan sat down on a chair.

Wang Tao looked at Liu Fan's confident expression, and suddenly reacted, his eyes lit up, "Can you solve the compatibility problem between applications and systems?!"

"alright."

"Then you didn't tell me earlier?!" Wang Tao was extremely excited.

Liu Fan spread his hands, "You didn't ask me either."

"Can't you take the initiative to say it?"

"I like to be passive."

Wang Tao: "."

Seeing Wang Tao choked, the others couldn't help but smile.

After laughing for a while, Ji Mushui put away everyone's emotions, "I believe Xiaofan has already thought about many things in the future. If this is the case, I think everyone can discuss the details and finalize this matter as soon as possible."

Everyone nodded and had a very serious discussion on feasibility, staffing, equipment, materials, safety, budget and other issues.

The meeting lasted for a whole day, and the research and development project of Kunxin Technology on new materials was finally finalized at their level.

In the evening, several people had dinner together. During the dinner, Zhang Rujin found an opportunity to come to Liu Fan and whispered, "AMAT wants to see you."

"Do you know what it is for?"

Zhang Rujin shook his head, "They didn't say much, and I couldn't ask more questions. But..."

Zhang Rujin hesitated to speak, but Liu Fan could understand what he meant, and he hoped to meet this side by himself.

The equipment and materials involved in the entire semiconductor industry are very large. For example, to manufacture a chip, you need a photolithography machine, a plasma etching machine, a reactive ion etching system, an ion implanter, a single crystal furnace, a wafer dicing machine, an oxidation process, etc. Furnace, low pressure chemical vapor deposition system, magnetron sputtering table, chemical mechanical grinding machine, etc.Not to mention in terms of materials, but why it seems that only lithography machines are often mentioned by the media, and Liu Fan only makes lithography machines?

On the one hand, it is because the lithography machine is very important, and the other reason is that the lithography machine is banned. So have other equipment been banned?In fact, we can only buy second-hand and outdated equipment for some equipment, but compared with lithography machines, we can purchase other equipment and materials smoothly. Among them, AMAT, the world's largest semiconductor equipment, Nano-manufacturing companies have played an important role.

Take Huaxin International as an example. Most of their equipment and materials are purchased from AMAT. If AMAT also imposes a sales ban like ASML, China's chip manufacturing industry will suffer even more.

So in general, AMAT is relatively friendly to China. Although this kind of friendship is based on interests, you must know that 22% of AMAT's material market is in China. If he abandons the China market, the loss will not be small.

And the company with the deepest cooperation relationship of AMAT in China should be Huaxin International. This time, the other party dragged Huaxin International to greet Liu Fan instead of calling Liu Fan himself. I don’t know if it is because of the current environment, but Huaxin International definitely It is hoped that Liu Fan will give the other party this face.

Liu Fan nodded and asked Zhang Rujin to ask the other party for the time.

For some reasons, Liu Fan also wanted to meet this company.
