I Have a Little Black Hole

Lei Tiantang just came over to have a look. He didn't have any specific goals, so he arranged casually, Let's start with the lab on a chip!

Good boss! It's really hard to say anything about this chip research. The 2-nanometer technology that our chip lab is currently investing in research and development is not progressing very well. It seems that it is only a small improvement from the 3-nanometer technology that our company is currently using. Step, it doesn't seem like a problem.

But this 1-nanometer gap has kept us busy for more than a year and has not fully overcome it. There are still some related technologies of lithography machines that have not been solved. The material problem of the chip also requires more experiments. One step has been able to anticipate the research time that the next 1 nanometer chip manufacturing technology may take! Liu Li sighed as he walked on both sides.

There is no way to do this. It is already very good that the laboratory on a chip can achieve the current achievements. Anyway, there is still a generation of technical reserves, so take it slow.

After all, the best products our company sells on the market today are 4-nanometer chips, which are a long time ahead of our competitors who are still using 5-nanometer technology.

Moreover, even if our company uses 5nm technology to process low-end chips, in terms of performance, because we have adopted a more intelligent chip architecture, the performance exceeds that of competitors' high-end products with the best performance. Therefore, in a short period of time, the company has You don't need to rush to work on surprise R\u0026D.

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 because of its late-mover advantage and abundant research funds, our researchers are also human.

There is no such thing as a breakthrough in the development of the picture in the movie, so we can only honestly and down-to-earth to overcome difficulties. Speaking of this, Lei Tiantang's mood is not very beautiful.

Although the company is still digging deep into the technical limits of 5nm technology and 4nm technology, every year because of optimizing chip design or stacking more layers on the chip, the performance of the chips sold by the company can be improved. The increase is more than 30%, but according to the current situation, this bonus can only last for about 5 years at most.

At that time, if there is no better breakthrough in these technologies, unless the company also chooses the more shameless multi-core technology to fool consumers, if the technology is not enough, it will pile up a few more chips. Lei Tiantang I don't want companies to do that.

This is because it is easy to give the outside world the impression that the talent is exhausted or mercenary, which is not a good thing for the company's image.

But if the chips of these two specifications really have exhausted the potential of the company, there is no better technology to solve the problem,

Then only the company's own 3-nanometer technology reserve technology can be put on the market.

If the better 2-nanometer technology or even the further 1-nanometer technology has not made a breakthrough by then, it will be a bit passive for the company.

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

Without this massive profit support, how could the company adopt an unlimited investment model in various laboratories so smoothly, and there is no way to continue to make huge investments in the space field without much return in a short period of time.

Therefore, Lei Tiantang attaches great importance to the development of the laboratory on a chip, but he is also very helpless, but as he said, it is useless for you to be anxious about the research.

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 current flow, and the gate plays the role of switch control.

The nanometer of a chip is actually the width of the gate of the transistor. The gate is shorter, and more transistors can be added on a wafer of the same size. Like a 7-nanometer chip, the gate has reached its limit, and if it is shortened, the distance of the electrons will not move enough, and the phenomenon of leakage will occur.

Whether it is competitors or Infinite Gravity Group, it is now possible to achieve 5 nanometers or even smaller chips, that is because the chip research and development scientists have proposed a unique chip technology method to implant transistors with a new structure to the size of a hairline in the semiconductor.

This new type of transistor is smaller in size, and the new technology has raised the chip manufacturing process to a new level. Even the manufacturing technology of the Infinite Gravity Group that can break through to 3 nanometer chips also benefits from this technology.

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

While chatting about the chip, the two walked into the chip lab on the 3rd floor. This floor plus the 4th and 5th floors above are all the site of the chip lab, which shows that the chip experiment The status of the room and how many problems need to be solved.

How many new materials have been tested in the laboratory now? How many are being tested? Which ones are promising? Lei Tiantang was curious after walking around the laboratory on the third floor. asked.

There are more than 2,800 new materials that have been really tested, and these new materials are all selected by the material company, and they are all materials that perform well in relevant basic tests.

However, if you add new materials that are directly eliminated in the simulation system, the number will exceed more than 23,000. Those materials that have not even passed the simulation test have good performance in some aspects, but it is difficult to require more Qualified in demanding chip material requirements.

After all, we require chip materials with better performance to at least achieve 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. Enter into the actual experiment in the laboratory.

There are still 372 kinds of related materials that we are doing now. These are all left over after multiple rounds of elimination. It is really hard to answer how many kinds of materials are very promising.
