Chapter 115: New material theory

"What material?" He Tingbo asked subconsciously.
"Graphene."
When I heard Liu Fan's answer, everyone's face changed differently. Graphene will be the chip material of the future for many years, which is also the most mainstream statement now.
If you go online, you can see that graphene is the most likely to become the chip material of the future, especially its advantages are very obvious, it is called the lightest and thinnest, the highest strength, the best toughness, the best conductivity, and the best heat conductivity. The material with the highest light transmittance.
IBM has invested 3 billion in graphene chips from 2014 to the present. However, because of the large amount of global research on graphene chips over the years, it has slowly made everyone realize that graphene does not seem to be so suitable. To make chips.
The first is that graphene also has many shortcomings, such as the lack of energy gap, and the excellent mechanical, chemical and electrical properties of graphene, which are not the most needed by chips now. Many people mention graphene chips and say these Advantages, but they do n’t matter how significant they are. The bottlenecks encountered in the current development of chips are composed of many problems, and similar to the difficulty of continuing to increase the frequency, obstacles to chip power consumption and bandwidth, etc., this can not be solved by simply changing the material to graphene.
There will be a problem. The graphene chip technology is still very backward, and the yield problem is very serious. Enterprises spend so much cost to design and produce graphene chips. As a result, many problems are still not solved, and the chip performance is still not as expected. After half a day, it was all useless.
Although many of you who are sitting at the core technology at this moment are entrepreneurs who do n’t understand technology, graphene has been burning for so many years, and the plight of graphene chips is more or less known, so when Liu Fan said that the new When the material is graphene, everyone is a little disappointed.
But this disappointment of this book 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 to combine graphene with traditional silicon materials, and I can get very good results."
凡 Liu Fan said, open the PPT, "This is the entire design principle."
"It's very similar to the graphene 3D chip principle of the Max team." Ji Mushui said with a glance.
"It's a bit similar." Liu Fan nodded. He has spent a lot of time studying architecture and materials in recent times, so he knows the Max team at MIT. "But if I look closely, I The design principle is fundamentally different from them.
The difference is that their design is based on traditional silicon materials, supplemented by graphene. In my design, graphene is used mainly, and traditional silicon materials are used as supplement. "
Fan Fan flipped through the PPT. "Graphene 3D technology is now very mature. In my entire design concept, the greatest significance of graphene is to achieve complex folding of materials and increase the sensitivity of transistors to light. And I use a very simple The dual-radial symmetrical structure and the use of erbium structure can allow silicon materials to have self-adjusting space in graphene materials, and this space can greatly solve the energy consumption problem. "
刘 With Liu Fan's more and more detailed introduction, everyone has a clear understanding of the application of this new graphene material.
But if this material is really usable, then Liu Fan ’s living water structure is likely to follow. At this time, some urgent problems will appear, such as Wang Tao ca n’t help but ask,
If we can have our own The architecture is a good thing, but how to solve the system problems? It is absolutely impossible for the win system to be opened to us. "
凡 Liu Fan looked at Wang Tao, and suddenly raised an eyebrow with annoyance, "Aren't you Huawei with your own system? Some time ago, you held the system to bang Lao Mi."
Wang Tao smiled helplessly, "Isn't that still worrying about their extreme shame? Using our autonomous system now is just the last move without a solution. Huawei cannot solve the ecological problem, and it needs to solve this problem. More time and energy than we expected. "
"Did you forget Mulong Technology?" Liu Fan took a seat on the chair.
Wang Tao looked at Liu Fan's confident expression, suddenly reacted, his eyes glowed, "Can you solve the compatibility problem between the application and the system?"
"alright."
"Then you said earlier ?!" Wang Tao was very excited.
凡 Liu Fan spread his hands, "You haven't asked me."
"Can't you take the initiative?"
"I like being passive."
Wang Tao: "..."
I saw Wang Tao being captive, the others couldn't help but smile.
After smirking for a while, Ji Mushui put away everyone's emotions, "I believe Xiaofan has already thought about many things later. Since this is the case, I think you can discuss the details and finalize this matter as soon as possible.
Everyone nodded and had a serious discussion on feasibility, staffing, equipment, materials, safety, budget and other issues.
The conference was held for a whole day, and the research and development project of new materials by Core Technology was finally finalized at their level.
In the evening, several people ate a meal together. During the meal, Zhang Rujin found an opportunity to whisper to Liu Fan. "AMAT wants to see you."
"Do you know what it is for?"
Zhang Rujin shook his head, "They didn't say much, I don't ask much. But ..."
如 Zhang Rujin wants to speak again ~ EbookFREE.me ~ But Liu Fan can understand what he means, and he hopes to see this himself.
The equipment and materials involved in the entire semiconductor industry are very large. For example, to manufacture a chip, a lithography machine, a plasma etching machine, a reactive ion etching system, an ion implanter, a single crystal furnace, a wafer scriber, and an oxide are required. Furnace, low pressure chemical vapor deposition system, magnetron sputtering table, chemical mechanical grinding machine, etc. Not to mention in terms of materials, but why does it seem that only lithography machines are often mentioned by the media all the time, and that Liu Fan has only made lithography machines?
On the one hand, because the lithography machine is important, and on the other hand, the lithography machine is banned. Are other equipment banned? In fact, we can only buy second-hand and backward equipment for some equipment, but compared to photolithography machines, we have generally purchased other equipment and materials smoothly. Among them, AMAT is the world's largest semiconductor equipment Nano manufacturing companies have played a very important role.
Take Huaxin International as an example, most of their equipment and materials are purchased from AMAT. If AMAT is banned like ASML, the chip manufacturing industry in China will be even more uncomfortable.
So in general, AMAT is relatively friendly to Huaxia. Although this friendship is based on benefits, we must know that AMAT has 22% of the material market in Huaxia. If he gives up the Huaxia market, he will not lose a small amount.
The company with the deepest AMAT partnership in China is probably Huaxin International. This time, the other party dragged Huaxin International to say hello to Liu Fan instead of calling it by themselves. I do n’t know if it is a worry about the current environment, but Huaxin International definitely It is hoped that Liu Fan will give each other this face.
凡 Liu Fan nodded and asked Zhang Rujin to ask the other party for time.
For some reasons, Liu Fan also wanted to meet this company ...
