I have a little black hole

Lei Tiantang also just came over to see, and there were no specific goals, so he arranged casually: "Let’s start with the chip lab!"

"Good boss! It's really hard to talk about this chip research. Our chip laboratory is currently investing in research and development of 2 nanometer technology and the progress is not very satisfactory. Step, I feel like the problem is not big.

But it is this gap of one nanometer that has kept us busy for more than a year, and we have not completely overcome it. There is still a part of the related technology of the lithography machine, and the material problem of the chip also needs more experiments. One step can already predict the research time that the next 1 nanometer chip manufacturing technology may take!"Liu walked bilaterally with emotion.

"There is no way to do this. The chip laboratory can achieve its current achievements very well. Anyway, there is still a generation of technical reserves. Slowly.

After all, our company's best product on the market today still uses 4nm technology chips, which has been a long time ahead of competitors who are still using 5nm technology.

Moreover, even if our company uses low-end chips processed with 5 nanometer technology, the performance is also because we have adopted a smarter chip architecture. The second reason is that it surpasses competitors’ best high-end products in performance, so the company has a short time It does not require you to rush to carry out 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 later came to rely on the advantages of latecomers and abundant research funds, but our researchers are also human.

There is no such thing as a breakthrough in the research and development of the pictures in the novels and movies, so we can only work hard to overcome the difficulties."When it comes to this, Lei Tiantang's mood is not very beautiful.

Although the company is still digging deeper into the technical limits of 5 nanometer technology and 4 nanometer technology, every year it will optimize the chip design or stack more layers on the chip, so that the performance of the chip sold by the company can be Increased by more than 30%, but according to the current situation, this bonus can only be up to 5 years.

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 more chips. I don't want the company to do this.

Because doing so is easy to give the outside world an impression that Jiang Lang is exhausted or profitable, which is not a good thing for the company's image.

But if these two specifications of chips really tap the potential of the company and there is no better technology to solve the problem, it can only put the company's own 3 nanometer technology reserve technology on the market.

If at that time the better 2 nanometer technology and even the further 1 nanometer technology could not make a breakthrough, it would be a bit passive for the company.

If competitors break through this technology in advance, it will be difficult for the company to earn more than 70 billion U.S. dollars from mobile phone chips, computer chips, supercomputers and related industrial chips every year Net profit.

Without this huge amount of profit support, how could the company so smoothly adopt an unlimited investment model in various laboratories, and there is no way to continue to make a huge investment in the space field that does not have much return in a short period of time.

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

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

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

Whether it is a competitor or the Infinite Gravity Group, it can now achieve a chip of 5 nanometers or even a smaller number. That is because the chip research and development scientists have proposed a unique chip technology method to implant a transistor with a completely new structure into the size of the hair. Of semiconductors.

This new type of transistor is smaller in size, and the new technology has raised the chip manufacturing process to a higher level. Even the infinite gravity group can break through to the manufacturing technology of 3 nanometer chips because of this technology.

Although with the continuous development of new technologies and materials, this limit size will continue to shorten, but from the company's laboratory to the present has not completely broken through the 2 nanometer technology, the closer you can see the point At the current limit of science and technology, it is not easy to continue to break through.

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

"How many kinds of new materials have been tested in the laboratory right now? How many are being tested? Which ones are promising?" Lei Tiantang was curious after a simple walk around the laboratory on the third floor. Asked.

"There are more than 2,800 new materials that have actually been tested. These new materials were selected by the materials company, and they are all materials with good performance in related basic tests.

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

After all, we require chip materials with better performance to have at least excellent electrical conductivity, mechanical properties, thermal conductivity and other related characteristics. 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 material research we are doing now. These are left over after many rounds of elimination. As for how many kinds of materials are very promising, it is really not easy to answer."
