Chapter 686 Theoretical Limit

A long text is displayed in front of everyone with some pictures and formulas.

"Brothers are people in the chip industry, and they all know that the raw material of chips is silicon. In the past, it was generally believed that 7 nanometers was the physical limit of silicon chips, and Moore's Law touched the ceiling. However, in the past two years, 7 nanometers The process has been realized, and it has achieved volume production. Our next goal is the 5-nanometer process, and I will now talk about the feasibility study of the 5-nanometer process.”

Wang Dequan introduced the chip technology to everyone enthusiastically, paused for a while and continued: "Since 7 nanometers was considered to be the physical limit of silicon material chips before, is it still possible to propose a 5 nanometer technology? The answer is yes. Yes, technology is developing, materials are developing, and everything is possible. The diameter of a silicon atom is 0.117 nanometers. In theory, it should be possible to achieve a process of 0.117 nanometers, which is 117 picometers. This is why I was in the conference room yesterday. Name one of the reasons for the 100-picometer process."

Speaking of this, there was a lot of discussion from the audience.

When discussing the chip research goal yesterday, Wang Dequan did put forward about 100 picometers, but he did not expect it to come like this.

However, the silicon atom is 117 picometers, which does not mean that the transistor can be so small, otherwise it would not have been considered that 7 nanometers was the physical limit of silicon materials.

Wang Dequan paused for a while and continued: "117 picometers, of course, is the current theoretical limit, but if it is 5 nanometers, this limit is much smaller. In fact, 5 nanometer technology has been studied by many international companies, and Some achievements have been made. If our company also wants to study the 5-nanometer process, we can use this idea to enter the 5-nanometer..."

Wang Dequan began to introduce his thoughts on the 5-nanometer process to the crowd.

Li Wenhao also sat aside and listened carefully to Wang Dequan's introduction. During the introduction, he nodded from time to time to express his approval.

"Brothers, the above content is my explanation of the feasible plan for the 5nm process, thank you."

After talking continuously for half an hour, Wang Dequan finally explained the introduction of the 5nm process.

As soon as the words fell, there was thunderous applause from the audience.

"Okay, this idea is very good. According to this direction, there is a great opportunity to develop a real 5-nanometer process."

"President Wang is worthy of being one of the main persons in charge of Huawei HiSilicon. His technical level is really high. As the saying goes, listening to your words is better than reading ten years of books. That's exactly what he said."

In fact, there are still many plans for the 5nm process. If we really want to expand it, it is not enough to talk about one day and one night.

Fortunately, the people here are all seniors in the chip industry. Many things are easy to understand when you hear them.

Li Wenhao also applauded. After listening to Wang Dequan's introduction to the feasible solution of the 5-nanometer process, Li Wenhao was also in awe of Wang Dequan. This is a person with a real level.

Although the 5-nanometer process in Li Wenhao's eyes is like a college student doing a primary school problem, it does not prevent him from recognizing Wang Dequan, because he knows that according to the feasibility study plan proposed by Wang Dequan, it is possible to truly manufacture a 5-nanometer process chip .

Li Wenhao picked up the microphone and said: "Thank you very much for the feasibility study plan given by Wang Gong. I have to say that this plan is very beautiful and has great feasibility. It is worthy of being a person who has worked in Huawei HiSilicon. It is inferior to the international leading technology level.”

After Li Wenhao came up, he directly praised Wang Dequan.

Just when everyone thought whether Li Wenhao was going to admit defeat, Li Wenhao changed his words: "The plan is really good, but compared to my plan, it's just garbage, and it's not worth mentioning."

Wang Dequan was about to explode his lungs when he heard it.

Compared with your plan, it is garbage and not worth mentioning.

Resist the anger in his heart.

Hehe, I would like to see what your so-called 60 pim process plan is.

You must know that the silicon atom is only 117 picometers, and you are now doing 60 picometers.

Is it possible to make transistors smaller than silicon atoms?

If you say you want to make chips with a 200-picometer process, you will be worried. Now, let's see how you step down.

Originally, I thought that after winning, I would give you some face.

It seems that there will be no need to give you face.

Wang Dequan was determined to pay attention. After winning, he must humiliate Li Wenhao and let him know what strength is. Only a person with strength is worthy of being the person in charge.

Chip research is not a game, and if you don't have the corresponding strength, you will go back to where you are.

Li Wenhao noticed Wang Dequan's face, but he didn't care too much. Those without strength are destined to be suppressed and humiliated.

Research in this industry relies on strength, and all false strengths will be invisible here.

Li Wenhao skillfully opened his own feasibility study plan, and a three-dimensional plan was presented in front of everyone.

Not only text, but also various videos, pictures, and tables as auxiliary.

On the surface, Li Wenhao's plan is much better than Wang Dequan's plan.

Wang Dequan naturally also noticed this. His previous plan was to prepare the data on the projector. He never thought that it would be displayed on the holographic projection, and the effect would be normal.

And Li Wenhao's plan is specially made for holographic projection, plus video and picture assistance, it looks very comfortable.

"There are flashy things, the focus of the plan is on the content, not on the surface." Wang Dequan muttered beside him.

Li Wenhao really didn't mean to show off. He was used to holographic projection technology in the apocalyptic world. When making plans, he naturally used a format that could be displayed on holographic projection videos.

What's more, because the existing technology needs to be used to realize the 60-picometer process, there are videos and pictures as auxiliary, which is easier for the viewers to understand.

The key to the competition between him and Wang Dequan lies in the following colleagues, so Li Wenhao took this into consideration when making the plan, and tried his best to introduce it in simple and easy-to-understand language.

Li Wenhao introduced: "Kong Gong also said before that the diameter of a silicon atom is 117 picometers. If you want to achieve a 60 picometer process, it is basically difficult to achieve. But don't forget that the technology in this world is constantly developing. Continuous progress. Or to apply Wang Gong's words, 7nm process was considered to be the physical limit of silicon materials in the past, but now some companies have begun to enter the 5nm process. As far as I know, some companies have broken through the 7nm process, The 5-nanometer process has truly been achieved, although it is still a while away from mass production, but I believe that mass production will be achieved in the near future.”
