Chapter 1013

Lei Tiantang just came to have a look. He didn't have any specific target, so he casually arranged: "let's start from the chip Lab!"

"Good boss! When it comes to chip research, it's really hard to say. The progress of 2-nanometer technology that our chip lab is now engaged in research and development is not very satisfactory. It seems that it is only a small step up from the 3-nanometer technology currently used by our company. It seems that the problem is not big.

However, we have been busy for more than a year, but we haven't completely overcome the gap of one nanometer. Part of the lithography related technology has not been solved, and the material problem of the chip also needs more experiments. From this step, we can predict the research time that the next 1 nm chip manufacturing technology may take! " Liu Li said with emotion while walking on both sides.

"There's no way to do it. The chip lab has made great achievements. Anyway, there is still a generation of technology reserves. Take your time.

After all, our company's best product on the market now also uses 4-nanometer technology chip, which is a long time ahead of those competitors who are still using 5-nanometer technology.

What's more, even the low-end chips manufactured by our company adopt 5-nanometer technology, in terms of performance, we have adopted a more intelligent chip architecture. Second, we have surpassed the high-end products with the best performance of our competitors. Therefore, the company does not need you to rush to carry out research and development in a short time.

After all, we all know that the development of traditional chip manufacturing technology has really entered a bottleneck period. Although our company has caught up with the advantages of latecomer and abundant research funds, our researchers are also human beings.

There is no such good thing that the screen in the novel and film will break through in a flash of research and development, so we can only be honest and down-to-earth to overcome the difficulties. " Speaking of this, Lei Tiantang's mood is not very beautiful.

Although the company is still constantly digging into the technical limits of 5-nanometer technology and 4-nanometer technology, the performance of chips sold by the company can be improved by more than 30% every year because of optimizing chip design or stacking more layers on the chip. However, according to the current situation, the dividend can only last about 5 years at most.

At that time, if there is no better breakthrough in these technologies, unless the company also chooses the shameless multi-core technology to fool the consumers, and if the technology is not enough, it will pile up more chips. Lei Tiantang does not want the company to do so.

Because it is easy to give the outside world an impression that they are at their wits' end or that they are mercenaries. This is not a good thing for the company's image.

But if the potential of these two specifications of chips is really exhausted, and the company has no better technology to solve the problem, then we can only put our own 3-nanometer technology reserve technology on the market.

If there is no way to make a breakthrough in better 2-nanometer technology or even further 1 nanometer technology, it will be a bit passive for the company.

If competitors break through this technology ahead of time, it will be very difficult for the company to make more than 70 billion US dollars of net profit every year from mobile phone chips, computer chips, supercomputers and related industrial chips.

Without this huge profit support, how could the company successfully adopt the unlimited investment mode in various laboratories, and there is no way to continue to make huge and non return investment in the space field in a short time.

So for the development of the chip laboratory, Lei Tiantang attaches great importance to it, but it is also helpless. However, as he said, it is useless for you to study things urgently.

There are hundreds of millions of transistors in the chip. Its structure is mainly composed of drain, source and gate. The drain and source are responsible for the current flow, and the gate plays the role of switch control.

For example, the nanometer of a chip is actually the width of the gate of a transistor. The gate is shorter, and more transistors can be added to a wafer of the same size. For example, the gate of 7Nm chip has reached the limit. If it is shortened, the distance of electron movement will not be enough and leakage will occur.

Whether competitors or infinite gravitation group can now achieve 5 nanometers, or even smaller digital chips, because chip research and development scientists have put forward a unique chip technology, which uses a new structure of transistors implanted into hair size semiconductors.

This new type of transistor is smaller in size, and the new technology makes the chip process upgrade to a higher level. Even the infinite gravitation group's manufacturing technology that can break through to 3 nm chips also benefits from this technology.

Although with the continuous development of new technologies and materials, this limit size will continue to be shortened, but from the company's laboratory to now has not completely broken through the 2 nanometer technology. It can be seen that the closer we are to the current limit of science and technology, it is not easy to continue to break through.

While chatting about the chip, they walked into the chip laboratory on the third floor. This floor, together with the fourth and fifth floors above, is the site of the chip laboratory. From this, we can see the status of the chip laboratory and how many problems need to be solved."How many new materials have been tested in the laboratory? How many are being tested? What are the promising ones? " After a simple walk around the laboratory on the third floor, Lei Tiantang asked curiously.

"There are more than 2800 kinds of new materials that have been tested. These new materials are all selected by the material company. They are all materials with good performance in relevant basic tests.

However, if we add the new materials that will be eliminated directly in the analog system, the number will be more than 23000. Although the materials that fail to pass the simulation test have good performance in some aspects, they are difficult to meet the more stringent requirements for chip materials.

After all, we require better chip materials, which at least have excellent electrical conductivity, mechanical properties, thermal conductivity and other related properties. Only materials that meet these basic conditions can pass the screening of the simulation test system and enter the laboratory experiments.

There are still 372 kinds of related materials that we are doing now, which are left after several rounds of elimination. As for how many materials are very promising, it is really hard to answer. "
