Chapter 685： Theoretical limit (1/2)

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

”Brothers are all people in the chip industry, and they all know that the raw material for chips is silicon. The previous view was that 7 nanometers is the physical limit of silicon material chips, and Moore's Law has touched the ceiling. However, in the past two years, 7 nanometers The process has been achieved and mass production has been achieved. Our next goal is the 5nm process, and what I am going to talk about now is the feasibility study of the 5nm process.”

Wang Dequan introduced the chip technology to everyone with an eloquence, and paused for a while and continued: ”Since 7nm was previously thought to be the physical limit of silicon material chips, is it possible to propose a 5nm process? The answer is yes. Yes, technology is developing and materials are developing. Everything is possible. The diameter of silicon atoms is 0.117 nanometers. In theory, it should be possible to achieve a 0.117 nanometer process, which is 117 picometers. This is why I met in the conference room yesterday. Name one of the reasons for the 100 picometer process.”

Speaking of this, there was a sound of discussion in the audience.

When discussing the goal of chip research yesterday, Wang Dequan indeed proposed about 100 picometers, which he did not expect.

However, the silicon atom of 117 picometers does not mean that transistors can be so small, otherwise 7 nanometers would not be considered the physical limit of silicon materials before.

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, many companies in the world have studied the 5 nanometer process and Certain achievements have been made. If our company also wants to study the 5nm process, we can use this idea to advance to 5nm...”

Wang Dequan began to introduce his thoughts on the 5nm process.

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.

”Dear brothers, the above content is my explanation of the feasibility of the 5nm process. Thank you.”

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

As soon as the voice fell, thunderous applause immediately rang out from the audience.

”Okay, this idea is very good. If you develop in this direction, there is a great opportunity to develop a real 5-nanometer process.”

”Mr. Wang deserves to be one of the main persons in charge of Huawei HiSilicon. The technical level is indeed high. It is said that listening to the king is better than reading ten years.”

In fact, there are a lot of plans for the 5nm process. In terms of development, it is not enough to talk about one day and one night.

Fortunately, the people here are all old people in the chip industry. There are many things, you know what's going on, and it's very easy to understand.

Li Wenhao also applauded. After listening to Wang Dequan's introduction of the feasibility of the 5nm process, Li Wenhao also respected Wang Dequan. He is a man of real level.

Although the 5-nanometer process in Li Wenhao’s eyes is like a college student doing elementary school topics, it does not hinder his recognition of 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 at Huawei HiSilicon. The level of technology is inferior to the international leading level.”

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

Just when everyone thought Li Wenhao was about to surrender, Li Wenhao changed his words: ”The plan is really good, but compared with my plan, it's just rubbish, not worth mentioning.”

Wang Dequan heard from the sidelines, he was about to blow his lungs.

What is meant by comparing it with your plan is rubbish, not worth mentioning.
