Vol 2 Chapter 1025: The limits of chip technology

Lei Tiantang just came to take a look, and didn't have any specific goals, so he arranged casually: "Let’s start from the lab on a chip!"
"Good boss! Speaking of this chip research, it's really hard to explain. The progress of the 2 nanometer technology that our chip laboratory is currently investing in research and development is not ideal. It seems to be a small improvement from the 3 nanometer technology that our company currently uses. Step, it feels like the problem is not big.
But it is this 1 nanometer gap that keeps us busy for more than a year and we have not completely overcome it. There are still some parts of the related technology of the lithography machine that have not been solved. The material problem of the chip also needs more experiments. One step has been able to predict the research time that the next 1nm chip manufacturing technology may take! "Liu Li said with emotion while walking.
"There is no way to do this. The lab-on-a-chip can achieve the current achievements is already very good, anyway, there is a generation of technical reserves, and it will take time.
After all, the best products our company currently sells on the market still use 4-nanometer technology chips, which have been ahead of those competitors who are still using 5-nanometer technology for a long time.
Moreover, even if our company uses 5 nanometer technology to process low-end chips, in terms of performance, we have adopted a more intelligent chip architecture. Second, it surpasses competitors' high-end products with the best performance in performance, so the company has a short time You do not need to hurry up and conduct surprise research and development.
After all, we all know that the development of traditional chip manufacturing technology has really entered a bottleneck period. Although our company has come from behind due to late-comer advantages 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 it will optimize the chip design or stack more layers on the chip, so that the performance of the company’s externally sold chips can be achieved. An increase of more than 30%, but according to the current situation, this bonus 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 consumers, if the technology is not enough, it will pile up a few more chips. I don't want the company to do that.
Because doing so can easily give the outside world the impression of being exhausted or profitable, which is not a good thing for the company's image.
But if the potential of these two specifications of chips is really exhausted, the company has no better technology to solve the problem, then it can only put the company's own 3nm technology reserve technology on the market.
If by that time there is no way to make a breakthrough with better 2nm technology or even further 1nm technology, it will be a bit passive for the company.
If a competitor breaks through this technology in advance, it will be difficult for the company to earn more than 70 billion U.S. 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 time.
Therefore, Lei Tiantang attaches great importance to the development of the lab-on-a-chip, but he is 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, and its structure is mainly composed of drain, source and gate. The drain and source are responsible for the flow of current, and the gate plays the role of switch control.
The nanometer of a chip is actually the width of the transistor gate. The gate is shorter, and more transistors can be added to the same size wafer. Like a 7-nanometer chip, the gate has reached its limit, and if it is shortened, the electrons will not travel enough distance and leakage will occur.
Whether it is a competitor or Infinite Gravity Group, it is now possible to achieve 5 nanometers or even smaller numbers of chips. That is because the chip research and development scientists put forward a unique chip technology method to implant a new structure of transistors into the size of a hair. In the semiconductor.
This new type of transistor is smaller, and the new technology has brought the chip manufacturing process to a higher level. Even Gravity Group's manufacturing technology that can break through to 3 nanometer chips is also benefited from this technology.
Although with the continuous research and development of new technologies and materials, this limit size will continue to shorten, but from the company’s laboratory to the present, it has not completely broken through the 2 nanometer technology. It can be seen that the closer At the limit of current science and technology, it is not easy to continue to break through.
While talking about the chip, the two walked into the lab on the 3rd floor. This floor plus the 4th and 5th floors above are all on the premises of the lab on a chip. This shows that the experiment on the chip 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?" After a short stroll in the laboratory on the 3rd floor~EbookFREE.me ~ Lei Tiantang asked curiously.
"There are more than 2,800 new materials that have been actually tested. These new materials are selected by the material company, and they are all materials that perform well in related basic tests.
But if you add new materials that are directly eliminated in the analog system, the number will exceed 23,000. Those materials that have not even passed the analog test have good performance in some aspects, but it is difficult to demand more Qualified performance in severe chip material requirements.
After all, we require better-performing chip materials to have at least excellent performance in electrical conductivity, mechanical properties, and thermal conductivity. Only materials that meet these basic conditions can pass the screening of the simulation test system. Enter the actual experiment in the laboratory.
There are still 372 kinds of related materials that we are doing now, which are left after multiple rounds of elimination. As for how many kinds of materials are very promising, it is really difficult to answer. "
