Rebirth of science and technology academic master

To be honest, even today, when Qin Yuanqing supports Huaxin Technology, there is still a big gap between China and Western countries in the field of high-end manufacturing of integrated circuits.

Apart from anything else, ASML's extreme ultraviolet lithography machine (EUV) alone brings together the most advanced manufacturing technologies from all Western countries and can be called the most compact industrial product in human history.

Together with aero engines, it has become a jewel in the crown of industrial manufacturing.

Qin Yuanqing also had to admit that in the era of silicon-based integrated circuits, Western countries had a huge first-mover advantage, and it was difficult for China to compete with Western countries in this field.

This is why China took the lead in mastering 5G technology, and then the world became a sensation. It is true that the dividends of the 3G era have not been eaten up, and the dividends of the 4G era have just begun to be eaten, and they are not full yet. As a result, Huawei mastered 5G technology. This Isn't it destroying other people's jobs?

What's even more disgusting is that as soon as 5G technology breaks through, China is already building 5G base stations. The speed is too fast.

That's why there was such a fuss.

Qin Yuanqing admitted that the gap in silicon-based chip manufacturing processes makes it difficult for China to catch up with Western developed countries in a short period of time. Even if it catches up, it cannot be called overtaking in a corner. But the fact that there is no way to overtake in the silicon-based field does not mean that there is no way to find another way.

Carbon nanotubes have high hopes from scientists!

This is closely related to its own characteristics. First of all, although the carbon nanotube chip is small in size, its energy-saving and efficiency-enhancing capabilities are more powerful. Carbon nanotubes are carbon materials rolled into a tube shape from a single layer of carbon atoms. They have excellent electrical conductivity, and carbon elements are abundant on the earth. Rich.

The diameter of carbon nanotubes can be made from a few nanometers to tens of nanometers in length depending on the process; the thickness of the tube wall is smaller. According to the number of carbon atoms in the wall layer, carbon nanotubes can be divided into single-walled carbon nanotubes and multi-walled carbon nanotubes. tube; at the same level of integration, carbon nanotube chips are smaller than silicon components.

At the same time, carbon nanotubes have extremely high toughness and can withstand stresses such as bending and stretching. The delay in the electrical signal transmission process is very short. Therefore, from the perspective of material physical properties, carbon nanotubes have the potential to replace silicon chips.

Secondly, carbon materials have a variety of allotropes. In addition to carbon nanotubes, there are also well-known diamonds, graphite, fullerenes, activated carbon, etc.

Its conductive properties strongly depend on its structure and can change from an insulator to a semiconductor and from a semiconductor to a conductor. Moreover, its conduction method and principle are different from traditional transistors, and it has stronger conductivity.

In addition, existing transistors will inevitably generate leakage current during the conduction process, and leakage will cause heat. Carbon nanotubes can avoid this problem, so the energy efficiency is relatively high.

Theoretically, the energy utilization rate of carbon nanotube chips is expected to exceed the energy efficiency ratio of existing chips (60% to 70%).

Solving the heating problem also reduces the pressure on the heat dissipation of the chip. Silicon transistors consume a lot of power. In a small chip space, the heating is extremely serious. In order to prevent the chip from overheating and unable to work, it is necessary to allocate part of the power consumption for The heat dissipation of the chip increases the power consumption of silicon transistors.

The carbon nanotube chip itself generates less heat, and the thermal conductivity of the carbon nanotube itself is very high, which effectively reduces the energy consumption for heat dissipation. Therefore, the energy efficiency of carbon nanotubes will be much higher than that of silicon. of transistors.

Worldwide, IBM was the first to realize the preparation of carbon nanotube devices. It successfully prepared a carbon nanotube 20nm gate length device in 2014. However, the performance of the device was much worse than expected.

In recent years, various foreign laboratories have claimed to have prepared carbon nanotube devices with a gate length of 1nm, but most of them are just gimmicks and their actual performance is very poor.

After Qin Yuanqing chose the direction of carbon-based chips, he began to lead the research on carbon nanotube devices. Then a large number of researchers realized the convenience and speed of having a big boss personally lead the way. Research and development was incredibly fast, and once they encountered bottlenecks and difficulties , Qin Yuanqing personally took action to solve the problem, and completed the mass production of ultra-high purity electronic-grade carbon nanotubes in a short period of time. Then the team began to prepare high-performance carbon nanotubes (CMOS complementary metal oxide semiconductor) transistors without doping. , conduct in-depth research on the polarity control of transistors.

"Academician Qin, good news!" On this day, Qin Yuanqing was working on algorithms, and Professor Pan came over and said happily.

"Oh? Professor Pan, what's the good news?" Qin Yuanqing asked curiously.

"Successful! The carbon-based chip is successful!" Professor Pan almost jumped up with excitement. Professor Pan, who is almost 48 years old, does not look stable at this moment.

He had no idea that within a month of Qin Yuanqing's arrival, the carbon-based chip would be successfully developed. This was simply incredible and inspiring!

With the carbon-based chip, Professor Pan is fully confident that the quantum computer can reach 2 bits, which will greatly increase the operating speed of quantum computers.

"Where?" Qin Yuanqing was also quite surprised. He was also thinking that this carbon-based chip would not be available until next year, or even the year after that. However, he did not expect that it would be available now. This was just before he left temporarily. The best news.

"Let's go, it's in the laboratory, everyone is so excited!" Professor Pan said, then led the way, followed by Qin Yuanqing.

When I arrived at the laboratory not far away, I saw Academician Guo jumping and screaming like a child, with tears in his eyes. Others were not much better.

Who would have thought that carbon-based chips would be born in their laboratory.

"Academician Qin, thank you, thank you!" Academician Guo's voice was choked when he spoke.

"Academician Guo, do you want me to take a look at the carbon-based chip?" Qin Yuanqing said with some embarrassment.

"Look, I am an old man who forgets when he is happy. Xiao Cao, take out the carbon-based chip and show it to Academician Qin." Academician Guo said, and then he saw a middle-aged man take out the key and unlock the cabinet. Lock, then put on gloves, and carefully took out a palm-sized brown glassware from the sample cabinet.

"Because it is made of carbon material, this chip is relatively sensitive to strong light sources, so we kept it inside!" Academician Guo explained.

After staring at the brown glassware for a while, looking at the thumbnail-sized chip lying quietly in the card slot in the center of the container, Qin Yuanqing asked: "Is it ready for testing?"

"We haven't had time to test it yet, and the testing phase will begin next!" Professor Pan said.

Qin Yuanqing nodded slightly. The birth of the carbon-based chip sample means China's leapfrog breakthrough from carbon-based transistors to carbon-based chips!

This shows that China has achieved overtaking in the field of carbon-based chips and is no longer afraid of being stuck in the future. It also means that quantum computers have ushered in the most suitable chip for them.

"Academician Guo, Professor Pan, I have almost completed the algorithm, and only the encryption algorithm is left." Qin Yuanqing said, "I have to return to the capital tomorrow to attend the Nobel Prize Award Ceremony with others, and wait until I get back. Complete the encryption algorithm."

Unknowingly, it was time for the Nobel Prize Awards. After Qin Yuanqing came to the University of Science and Technology of China again, he also achieved great results. First, Huaxia quickly reached the world's top level in carbon-based transistors. Now the birth of carbon-based chip samples means that Huaxia has become The first country in the world to master carbon-based chips has a head start. It will undoubtedly have a first-mover advantage in the field of carbon-based chips in the future, and will therefore have an absolute say in the formulation of standards. In terms of patents for carbon-based chips, We can also take the lead in the Internet, learn from those patent trolls in the West, and become a patent troll in the new era.

Of course, the carbon-based chip samples are now laboratory products. A series of tests will be conducted next to test the performance of the carbon-based chips and explore related carbon-based chip manufacturing processes. From carbon-based chip laboratory products to commercialization, there is no Three to five years is probably a bit of a stretch.

First-rate companies make standards, second-rate companies make brands, and third-rate companies make products!

This sentence is still timeless!

Whoever takes the lead will have a greater say in setting standards.

Why is Qualcomm so rich in the 3G era? Isn’t it because Qualcomm controls the core technology and has a great say in standards, making it difficult for latecomers to avoid Qualcomm and can only pay Qualcomm tax honestly.

Therefore, after suffering a lot and paying a lot of tuition, Huaxia also began to participate in the formulation of standards and strive for its own best interests. It is because standards represent the best interests, and the interests are more important than the brand.

Of course, in terms of algorithms, Qin Yuanqing has basically done it by himself. The entire set of algorithms is more than ten times stronger than the original algorithm. The algorithms originally formulated by the quantum computer algorithm team were simply stinky and long, and were directly overturned by Qin Yuanqing.

"Okay, then we wish Academician Qin that you will come back with the cup!" Academician Guo said with a smile: "We will also work hard to re-create a quantum computer and test the performance of the carbon-based chip, so as to give a gift to the people of the country in the New Year!"

Qin Yuanqing smiled and said, New Year's gift. Domestic scientific research institutions are particularly popular about this. I don't know what to say. Qin Yuanqing has no special feelings about this tradition. However, domestic scientific research institutions always hope to announce the latest results on the occasion of the New Year and give it to the people of the country. A New Year gift.

Professor Pan personally drove Qin Yuanqing to the airport. When leaving, Professor Pan repeatedly and sincerely thanked Qin Yuanqing for his contribution to quantum computers. Their project team will definitely report to their superiors truthfully.

Qin Yuanqing smiled and said nothing. In fact, it didn't matter to him whether he could repay him or not. After all, he was already at the top of the Chinese scientific community. He could see all the mountains and small mountains at a glance. He no longer needed the added bonus of fame to maintain him. right to speak.
