Chapter 523

"Ha ha, that's what I'm talking about. I'm really looking forward to the expression of those people who know that the performance of the chips that we're going to release this time is already abridged, which is beyond the most advanced products in their company's laboratory. They're going to be crazy!" Kuafu said happily.

"Yes, the performance of castration version is enough to punish them. If the product with complete performance is released, they will be crazy!

However, it is impossible for us to improve the performance of the chip to about 30 times as much as it is now. It is enough to shock them that the chip we are ready to release is 5 times higher than the top performance chip on the market.

Our company is also stained with the light of new materials, we are the production of graphene, we have enough understanding of its performance, which can make a breakthrough in such a short time.

We can't take those companies lightly. Now we are all developing chips based on graphene. If they make a breakthrough, we will be overtaken immediately! " Lei Tian Tang said with a smile.

That's right. But there's nothing to worry about. It depends on the fact that our company's high-quality graphene has been sold for more than a year, and the laboratories of those countries and companies have not really made technological breakthroughs. This shows the difficulty of developing graphene chips!

"Boss, you don't know the difficulty of technological breakthrough! Anyway, even if we release the primary product of 7 nm process, the performance is good enough!

If those countries and companies have made technological breakthroughs, then we will release the most advanced products of 5 nm process!

In any case, the 7 nm process is the physical limit of silicon chip, not the limit of graphene material we use. Although the technology of our lithography machine and other equipment comes from them, after we know their technology, our own optimized and upgraded product performance has broken through their technology!

It's almost no difference for our devices whether to produce 7Nm chips or 5nm chips! " Kuafu said without any care.

Moore's law, which has been applied for more than 20 years, has shown signs of failure in recent years. From the point of view of chip manufacturing, 7Nm is the physical limit of silicon chip, and Kuafu's 7Nm limit is what Kuafu said.

Today's CPU is integrated with transistors in the unit of 100 million. This transistor is composed of source, drain and gate between them. The current flows from the source to the drain, and the gate controls the current on and off.

The so-called XX nanometer actually refers to the gate width of complementary oxide metal semiconductor field-effect transistor formed on the CPU, also known as gate length.

The shorter the gate length, more transistors can be integrated on the same size silicon chip. When the integration degree of the chip transistor is equal, the area and power consumption of the chip will be smaller and the cost will be lower by using more advanced manufacturing technology.

Shortening the gate length of transistors can make CPU integrate more transistors or reduce the area and power consumption of transistors, and reduce the cost of silicon chip of CPU.

Therefore, CPU manufacturers spare no effort to reduce the gate width of transistors to increase the number of transistors integrated per unit area.

However, this method will also shorten the distance of electron movement, which will easily lead to the spontaneous movement of electrons inside the transistor from negative to positive through the silicon base plate of transistor channel, that is, leakage.

Moreover, as the number of transistors in the chip increases, the silicon dioxide insulation layer which is only a few atomic layers thick will become thinner and lead to more electrons leakage, and then the leakage current will increase the additional power consumption of the chip.

In order to solve the problem of electric leakage, various companies have shown their magic powers. For example, in the manufacturing process, high dielectric film and metal gate integrated circuit are integrated to solve the leakage problem;

there is FinFET technology, which increases the capacitance value by increasing the surface area of the insulation layer, and reduces the leakage current to prevent electronic transition .

the above method can effectively solve the leakage problem when the gate length is greater than 7 nm. However, on the basis of the existing chip materials, once the gate length of the transistor is less than 7 nm, the electrons in the transistor are easy to produce tunneling effect, which brings great challenges to the chip manufacturing.

To solve this problem, it is an effective solution to find new materials to replace silicon to make transistors below 7 nm.

This is also an important reason why since Lei Tiantang's company sold high-quality graphene to the outside world, many companies have begun to increase their investment in research and development of graphene chips.

"Not to mention this, although our company has made a breakthrough in graphene chips, the future of graphene chips is just like that!

It's enough to leave a team to continue in-depth research and development. Just keep a certain technology leading line. Other people still invest in the research and development of quantum computer chips. This is the direction of chip research and development in the future.

With the current strength of our company, there is still a lot of work to be done if we want to make a breakthrough in this area! " Lei Tian Tang said with a smile."Yes, the future... I'm looking forward to what I'll look like after I've evolved successfully at that time!" Kuafu continued to look forward to saying.

"Ha ha! Now don't think about these things that have no shadow. Let's continue to do our research in a down-to-earth way. Let's have a look at the experimental process I designed...

their discussion has not affected the normal development of the matter at all. With the increasing attention paid to this super prize competition, the infinite gravitation group is about to release The discussion of chip performance is getting hotter and hotter. Everyone is looking forward to their company's press conference.

The time also flows quickly in their expectation, and the day of press conference comes in a twinkling of an eye. Due to the company's frequent press conference, infinite gravity group is now very proficient in how to prepare for press conference.

Looking at the expectant eyes, Kong Yu said with a confident smile: "welcome to the press conference of infinite gravity group again!

There are two themes in this press conference. One is to give you a detailed introduction to the spaceship design competition with a total prize of RMB 10 billion announced on the official website of our company.

The other is to officially release our company's own high-performance chips based on graphene material! I know you can't wait to ask questions now! "
