Chapter 686: New Materials

Some people may ask, after all this talk, it seems to be talking about nanotechnology, but it seems that Pimi technology has not been mentioned yet? "Li Wenhao smiled confidently on the stage, "Don't worry, now listen to me talking for you." "
Everyone in the audience was attentive, for fear of missing some important details. This may become the idea to start the Pimi era, 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 another material that is very suitable as a raw material for chips, and that is graphene.

Sitting aside, Wang Dequan frowned slightly. Hearing this, he probably guessed Li Wenhao's design direction.
The idea of ​​using graphene as the raw material for chips is actually not the first one proposed by Li Wenhao. 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 material. Ene transistor.
Graphene chips are not entirely made of graphene, but are 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 or other aspects.
However, with current science and technology, there are still many problems in graphene that need to be solved. In a short period of time, it is impossible to complete. However, it has to be said that this view raised by Li Wenhao is very likely to become the key to the next stage.
Wang Dequan even feels that if he wants chips to enter the picometer era, the key lies in graphene.
But in the so-called picometer era, it is impossible for the chip to suddenly enter the exaggerated level of 60 picometers.
Although Wang Dequan didn't believe it, he still pricked his ears, wanting to hear how Li Wenhao realized the so-called 60 picometer craft.
When Li Wenhao mentioned graphene, others also suddenly realized.
Everyone is no stranger to graphene materials, or even a bit familiar.
This is also a very normal thing. Since the birth of graphene, its name has not only been well-known in the scientific community, but even among ordinary people.
Li Wenhao showed a faint smile, and while manipulating the holographic projection screen, he continued to introduce: "As for graphene, everyone knows its characteristics. Compared with traditional transistors, carbon tubes are smaller and more conductive. Performance and energy consumption are also far better than traditional silicon. However, it is unimaginable to make chips using pure graphene as a raw material. However, we can use graphene as an auxiliary material. With the existing silicon material, this can solve the problem that graphene is difficult to use as a chip. Not to mention the 60 picometer process, even if it surpasses the picometer, it is not impossible to reach the next stage."
Li Wenhao didn't speak big words. Compared with traditional silicon materials, the performance of chips made of graphene is many times stronger than that of silicon.
Chips in the apocalyptic world use graphene as the main material. At that time, there was still no chip with pure graphene as the raw material. However, semiconductor materials with graphene as the main material and supplemented by other materials are important in the chip industry. Shine.
If you compare the chips made in the apocalyptic world with the current silicon materials, the performance and speed will increase by at least a million times.
This is an exaggerated number, but it also proves the horror of graphene from the side.
It is hard to imagine, if there is a tube made of pure graphene, how strong will the performance increase?
Li Wenhao doesn't know, because this is also the direction of his struggle.
Although it is impossible to make graphene chips like those in the apocalyptic world with existing machines, chips with silicon as the main material and graphene as auxiliary materials are more than enough to make.
As soon as Li Wenhao’s words fell, Wang Dequan on the side immediately questioned:
President Li, the performance of graphene is indeed good, but how to make graphene work on silicon materials and how to find materials that can perform the 60 picometer process? You know, there are many types of materials. Although graphene has not been discovered for a long time, there are millions of materials based on graphene. How can we find materials suitable for making chips?"
Wang Dequan is not simply raising the bar. The questions he raised are also relatively real.
Everyone knows that the performance of graphene is very good, 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 a 7-nanometer process to a 5-nanometer process.
"Wang Gong, this question is well raised, but I have found this brand new material. The next step is to introduce this semiconductor material suitable for chip production."
Li Wenhao was not angry about Wang Dequan's question, but secretly gave a thumbs up to Wang Dequan for such cooperation.
"Everyone, please take a look. This is the new material I have discovered recently, a material mainly made of silicon and supplemented by graphene. This is his structure and an introduction to his performance..."
With a long video, pictures and other materials, Li Wenhao began to explain the characteristics of the new material.
Isn't it?
Did Mr. Li really find a new material suitable for chips?
According to Mr. Li's introduction, with this new type of material, I am afraid it can really break through the nano process and enter the pico process.
The people below didn't believe it at first, but with Li Wenhao's detailed introduction, everyone knew more about this brand-new material and believed that it was really the foundation of the future chip industry.
If this is true, they believe that the release of information about this brand new material ~EbookFREE.me~ 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, this limit is only broken to 5 nanometers and 3 nanometers.
The new material introduced in Li Wenhao's copy is a material that can bring the technological level of the chip into the picometer era, which is a material that has transcended the era.
After introducing it for half an hour, Li Wenhao finally finished introducing the new material.
"Do you have any questions?"
Li Wenhao asked.
Originally, the introduction of a material was introduced quickly, but during the introduction, people were often interrupted, and the most interrupted was Wang Dequan sitting aside.
