I Have a Little Black Hole

Haha, that's what I said, I really look forward to the expressions of those people after knowing the performance of our company's upcoming chip. If they know that the performance of the chip we are about to release this time is already abridged, it will surpass them. The most advanced products in the company's laboratory, then they are probably going crazy! Kuafu said cheerfully.

Yeah, the performance of the castrated version is enough to hang them, if a product with full performance comes out, then they must be crazy!

However, it is impossible for us to increase the performance of the chip by about 30 times now, and it is enough to shock them that we are going to release 5 times the top performance chip on the market.

Our company is also dipped in the light of new materials. We are the manufacturer of graphene ourselves, and we have enough understanding of its performance to achieve breakthroughs in such a short period of time.

We can't take those companies lightly. Now everyone is developing chips based on graphene materials. If they make breakthroughs, our advantages will be caught up immediately! Lei Tiantang said with a smile.

I said so, but if I really worry about it, there is nothing at all. It depends on the company's high-quality graphene that has been sold for more than a year. The laboratories of those countries and companies have not really made technological breakthroughs. , you can see the difficulty of developing graphene chips!

Boss, it's not that you don't know the difficulty of technological breakthroughs! Anyway, even if we release the primary products of the 7nm process, the performance is good enough!

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

Anyway, the 7-nanometer process is the physical limit of silicon material chips, not the limit of the graphene material we use. Although the technology of our lithography machine and other equipment comes from them, after we understand their technology, we optimize it ourselves. The upgraded product performance has surpassed their technology!

Whether it's 7nm or 5nm, it makes almost no difference to our device! ' said Kuafu indifferently.

Moore's Law, which has been applicable for more than 20 years, has gradually shown signs of failure in recent years. From the point of view of chip manufacturing, 7nm is the physical limit of silicon material chips, and the 7nm limit that Kuafu said is this.

The current CPU integrates transistors in units of billions. This transistor consists of a source, a drain and a gate between them. The current flows from the source to the drain, and the gate controls the current on and off. effect.

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

Also known as gate length.

The shorter the gate length, the more transistors can be integrated on the same size of silicon wafer. In the case of the same level of transistor integration in the chip, using a more advanced manufacturing process, the chip area and power consumption will be smaller, and the cost will be higher. Low.

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

It is for this reason that CPU manufacturers spare no effort to reduce the gate width of transistors to increase the number of transistors integrated per unit area.

However, this approach will also shorten the distance that the electrons move, which is likely to cause the electrons inside the transistor to spontaneously flow from the negative electrode to the positive electrode through the silicon base plate of the transistor channel, that is, leakage.

And as the number of transistors in a chip increases, the insulating layer of silicon dioxide, which is only a few atomic layers thick, gets thinner and leaks more electrons, which in turn adds extra power to the chip.

In order to solve the leakage problem, various companies can be said to have crossed the sea, each showing their magical powers, such as integrating high-dielectric films and metal gate integrated circuits in the manufacturing process to solve the leakage problem;

There is also fin field effect transistor technology (FinFET) - by increasing the surface area of ​​the insulating layer to increase the capacitance value, reduce leakage current to prevent electronic transitions...

The above method can effectively solve the leakage problem to a certain extent when the gate length is greater than 7 nanometers. However, on the basis of using existing chip materials, once the gate length of the transistor is less than 7 nanometers, the electrons in the transistor will easily have a tunneling effect, which brings huge challenges to the manufacture of the chip.

In response to this problem, finding new materials to replace silicon to make transistors below 7 nanometers is an effective solution.

This is also an important reason why Lei Tiantang's company has begun to increase investment in research and development of graphene chips since Lei Tiantang's company sold high-quality graphene.

Let's not talk about this, although our company has made breakthroughs in graphene chips, the future of graphene chips is just like that!

It is enough to leave a group to continue in-depth research and development, and it is enough to maintain a certain technological lead. Others are still invested in the research and development of quantum computer chips. This is the research and development direction of future chips.

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 Tiantang said with a smile.

Yeah, the future... I'm looking forward to what I will look like when I evolve successfully at that time! Kuafu continued to look forward to it.

Haha! Don't think about these things that don't have a shadow now, let's continue our research down-to-earth, and look at the experimental process I designed...

The discussion between the two of them did not affect the normal development of things at all. As the outside world pays more and more attention to this ultra-high prize competition, the discussion about the chip performance to be released by the Infinite Gravity Group is also getting hotter and hotter. , everyone is looking forward to their company's press conference.

And time also flew by in their expectations, and the day of the press conference came in a blink of an eye. Due to the company's frequent press conferences, Infinite Gravity Group is now very proficient in how to prepare for press conferences.

Looking at the expectant eyes from the audience, Kong Yu smiled confidently and said, We welcome everyone to attend this press conference of our Infinite Gravity Group again!

This press conference has two themes. One is to introduce to you the details of the spaceship design competition with a total prize of 10 billion RMB that our company recently announced on the official website.

The other is to officially release various high-performance chips based on graphene materials developed by our company to the outside world! I know everyone can't wait to ask questions right now!
