Chapter 687 New Materials

"Some people may ask, after talking so much, they seem to be talking about nanotechnology, but it seems that they haven't talked about pimi technology?" Li Wenhao showed a confident smile on the stage, "Don't worry, listen to me now for you. Come."

Everyone in the audience was attentive, for fear of missing some important details. This may become the idea of ​​​​opening the era of Pimi, and we must listen carefully.

Li Wenhao continued: "In addition to silicon, there are actually many semiconductor materials that can be used as raw materials for chips. In addition to silicon, there is actually a material that is very suitable as a raw material for chips, that is graphene."

Wang Dequan, who was sitting on the side, frowned slightly. Hearing this, he probably guessed Li Wenhao's design direction.

In fact, Li Wenhao was not the first to put forward the idea of ​​using graphene as the raw material for chips. As early as 2010, a team led by Lin Yuming, a scientist at IBM's Thomas Watson Research Center, showed the world the first graphite-based chip. ene transistors.

Graphene chips are not entirely made of graphene, but also mixed with other materials.

If this kind of chip can really be realized, it is indeed much better than silicon material, and it is far superior to silicon in terms of performance and other aspects.

However, with the current science and technology, there are still many problems in graphene that need to be solved, and it is impossible to complete in a short period of time, but I have to say that this point of view proposed by Li Wenhao is very likely to become the key to the next stage.

Wang Dequan even had a feeling that perhaps the key to entering the pico era for chips lies in graphene.

But in the so-called picometer era, it is impossible for the chip to enter the exaggerated level of 60 picometers at once.

Although Wang Dequan didn't believe it, he still pricked up his ears and wanted to hear how Li Wenhao achieved the so-called 60 pim process.

When Li Wenhao said graphene, others suddenly realized.

Everyone is familiar with graphene materials, and it can even be said to be a little familiar.

This is also a very normal thing. Since the birth of graphene, its name has become famous not only in the scientific community, but even among ordinary people.

Li Wenhao showed a faint smile and continued to introduce while controlling the holographic projection screen: "As for graphene, everyone knows its characteristics. Compared with traditional transistors, carbon tubes are smaller in size and stronger in conductivity. The performance and energy consumption are also far better than traditional silicon. However, it is difficult to imagine how difficult it is to use pure graphene as a raw material to make a chip. However, we can use graphene as an auxiliary material, With the existing silicon material, it can solve the problem that graphene is difficult to use as a chip. Not to mention the 60 picometer process, even if it exceeds picometer, it is not impossible to reach the next stage."

Li Wenhao didn't say big things. Compared with traditional silicon materials, the performance of chips made of graphene as raw materials is many times stronger than chips made of silicon.

The chips in the apocalyptic world are made of graphene as the main material, and in that era, there is still no chip with pure graphene as the raw material, but the semiconductor materials with graphene as the main material and other materials as supplements are very important in the chip industry. shine.

If the chips in the apocalyptic world are compared with the current silicon materials, their performance and speed will be improved by at least a million times.

This is an exaggerated figure, but it also proves the horror of graphene from the side.

It is hard to imagine how strong the performance improvement will be if there are tubes made of pure graphene?

Li Wenhao does not know, because this is also the direction of his struggle.

Although it is impossible to make graphene chips like the one in the apocalyptic world with existing machines, chips with silicon as the main material and graphene as the auxiliary material are more than enough to make.

As soon as Li Wenhao's voice fell, Wang Dequan on the side immediately questioned: "Mr. Li, the performance of graphene is really good, but how to make graphene work on silicon materials, how to find materials that can play a 60-picometer process, You must know that there are many types of materials. Although graphene has not been discovered for a long time, there are thousands of graphene-based materials. How to find materials suitable for making chips?"

Wang Dequan did not simply raise the bar, the questions he raised were also relatively real ones.

Everyone knows that the performance of graphene is very good, and it is many times better than traditional silicon materials.

But if you want to make graphene into a chip, the difficulties that need to be overcome are not a little bit. Every problem is overcome, no less than the promotion of the 7-nanometer process to the 5-nanometer process.

"Wang Gong, this is a good question, but I have already found out about this brand-new material. The next step is to introduce this semiconductor material suitable for chip manufacturing."

For Wang Dequan's question, Li Wenhao was not angry, but secretly gave a thumbs up to Wang Dequan's cooperation.

"Everyone, please see, this is the new material I recently discovered, a material mainly composed of silicon and supplemented by graphene. This is his structure and his performance introduction..."

With the long videos, pictures and other materials, Li Wenhao began to explain the characteristics of new materials.

isn't it?

Did Mr. Li really find a new material for chips?

According to Mr. Li's introduction, with this new material, I am afraid it can really break through the nanotechnology and enter the pico technology.

The following people were a little unconvinced at first, but with Li Wenhao's detailed introduction, everyone knew more about this brand-new material, and they believed more that it was really the foundation of the future chip industry.

If this is true, they believe, the release of information about this brand-new material may cause a huge sensation.

You know, the world has been looking for new materials to replace traditional silicon materials for too long.

As mentioned before, the 7-nanometer process has approached the physical limit of traditional silicon. Even if a brand-new technology is used, it will only break the limit to 5 nanometers or 3 nanometers.

The new material introduced in Li Wenhao's copy is a material that can bring the technology level of the chip into the picometer era, which is a material that spans the times.

After half an hour of introduction, Li Wenhao finally finished introducing this new material.

"Do you have any questions?"

Li Wenhao asked.

Originally, the introduction of a material was very fast, but during the introduction process, people were often interrupted, and Wang Dequan who was sitting on the side was the one who interrupted the most.
