Vol 2 Chapter 533: The most basic styles will hit you!

"Haha, what I said, I really look forward to the expressions of those people after they know the performance of our company's upcoming chip. If they know that the chip we are going to release this time, its performance will already exceed them. The most advanced product in the company's laboratory, they are probably going crazy!" Kuafu said cheerfully.
"Yes, the performance of the castrated version is enough to beat 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 to about 30 times the current performance at once. The chip that we are planning to release 5 times the top performance on the market is enough to shock them.
Our company is also immersed in the light of new materials. We ourselves produce graphene. We have enough understanding of its performance to achieve a breakthrough in such a short time.
Nor can we take those companies lightly. Now everyone is developing graphene-based chips. If they make a breakthrough, our advantages might be caught up immediately! "Lei Tiantang said with a smile.
That’s the case, but I’m really worried. It’s not at all. It’s just that the high-quality graphene of my company has been sold for more than a year, and the laboratories of those countries and companies have not really made technological breakthroughs. , You can see the difficulty of developing graphene chips!
"Boss, you don't know the difficulty of technological breakthroughs! Anyway, even if we release a 7-nanometer process, the performance of the primary product is good enough!
If those countries and companies have achieved 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, and not the limit of the graphene materials we use. Although our photolithography machines and other equipment are all from them, we have learned their technology and optimized it ourselves. The upgraded product performance has broken through their technology!
Whether to produce 7-nanometer chips or 5-nanometer chips, there is almost no difference for our equipment! "Quafu said indifferently.
Moore's Law, which has been applied 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 this is what Kuafu said.
The current CPU integrates a transistor in the unit of 100 million. This transistor is composed of a source, a drain, and a gate located between them. The current flows from the source to the drain, and the gate controls the current on and off. The role of.
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, which is also called the gate length.
The shorter the gate length, the more transistors can be integrated on a silicon wafer of the same size. In the case of similar chip transistor integration, the use of more advanced manufacturing processes will reduce the area and power consumption of the chip, and the more cost low.
Reducing the length of the transistor gate can enable the CPU to integrate more transistors or effectively reduce the area and power consumption of the transistors, and reduce the cost of the CPU's silicon.
It is precisely for this reason that CPU manufacturers have spared 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 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, which is leakage.
Moreover, as the number of transistors in the chip increases, the silicon dioxide insulating layer, which is only a few atomic layers thick, becomes thinner and causes more electrons to leak. The subsequent leakage current increases the additional power consumption of the chip.
In order to solve the leakage problem, each company can be described as the eight immortals crossing the sea, each showing their magical powers, such as the integration of 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 and reduce the leakage current to achieve the purpose of preventing 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, based on the use of existing chip materials, once the transistor gate length is less than 7 nanometers, the electrons in the transistor are prone to tunneling effect, which brings huge challenges to chip manufacturing.
In view of 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 various companies have begun to increase investment in graphene chip research and development since Lei Tiantang's company sold high-quality graphene to the outside world.
"Don't 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 team to continue in-depth research and development. 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 direction of future chip research and development.
With the current strength of our company, there is still much work to be done if we want to make a breakthrough in this area! "Lei Tiantang said with a smile.
"Yes, in the future..., I am looking forward to what I will look like after successful evolution at that time!" Kuafu continued looking forward to it.
"Haha! Don't think about these things that have no shadow now~EbookFREE.me~ Let us continue our research down-to-earth, you see how this experimental process I designed..."
The discussion between the two of them did not affect the normal development of things in the slightest. As the outside world pays more and more attention to this super-high prize competition, the discussion about the performance of the upcoming chip of Infinite Gravity Group has become more and more heated. , Everyone is looking forward to their company’s press conference.
And time flew by in their expectations, and in a blink of an eye came the day of press conferences. 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 little eyes in the audience, Kong Yu smiled confidently and said: "Welcome everyone again to participate in this press conference of our Infinite Gravity Group!
This press conference will have two themes. One is to give you a detailed introduction to the spacecraft design competition that our company recently announced on the official website with a total prize of 10 billion yuan.
The other is to officially release to the outside world various high-performance chips based on graphene materials developed by our company! I know everyone can't wait to ask questions now! "
