Chapter 372 The advent of carbon-based chips
To be honest, even today, Qin Yuanqing supports Huaxin Technology, but there is still a big gap between Huaxia and Western countries in the field of high-end integrated circuit manufacturing.

Among other things, ASML's extreme ultraviolet lithography machine (EUV) brings together the top manufacturing technologies of 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 has to admit that in the era of silicon-based integrated circuits, Western countries have a huge first-mover advantage, and it is difficult for China to compete with Western countries in this field.

This is also why, Huaxia was the first to master 5G technology, and then the world became a sensation. In fact, the dividends of the 3G era have not been eaten yet, and the dividends of the 4G era have just begun to be eaten, and they are not full yet. As a result, Huawei has mastered 5G technology. Isn't it smashing people's jobs?

What's even worse is that as soon as 5G technology breaks through, Huaxia is already building 5G base stations, which is too fast.

That's why there was such a commotion.

Qin Yuanqing admitted that the gap in the silicon-based chip manufacturing process made it difficult for China to catch up with Western developed countries in a short period of time, and even if it did catch up, it would not be called overtaking on a curve.However, the inability to overtake in a corner in the silicon-based field does not mean that there is no other way.

Carbon nanotubes are placed high hopes by scientists!

This is closely related to its own characteristics.First of all, although the carbon nanotube chip is small in size, its ability to save energy and increase efficiency is even stronger. Carbon nanotubes are carbon materials rolled into a tubular shape by a single layer of carbon atoms. Rich.

The diameter of carbon nanotubes can be made from several nanometers to tens of nanometers according to different processes; 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; in the case of the same level of integration, carbon nanotube chips are smaller than silicon components.

At the same time, carbon nanotubes have extremely high toughness, can withstand stress such as bending and stretching, and the delay in the transmission of electrical signals 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 well-known diamonds, graphite, fullerenes, activated carbons, and the like.

Its conductive properties are strongly dependent on the structure, and can be transformed from insulators to semiconductors and from semiconductors to conductors.Moreover, its conduction method and principle are different from traditional transistors, and it has stronger conduction ability.

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

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

The solution to the heating problem also reduces the pressure on the heat dissipation of the chip. The power consumption of silicon transistors is very large. In a small chip space, the heat generation is extremely serious. In order to prevent the chip from overheating and unable to work, part of the power consumption needs to be allocated for The heat dissipation of the chip, which makes the power consumption of silicon transistors increase.

The carbon nanotube chip itself produces less heat, and the thermal conductivity of the carbon nanotube itself is very high, which effectively reduces the energy consumption for heat dissipation, so the energy efficiency of the carbon nanotube 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 2014nm gate length device in 20. However, the performance of the device was much worse than expected.

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

After Qin Yuanqing chose the direction of carbon-based chips, he began to lead the research of carbon nanotube devices, and then a large number of researchers realized that the convenience and speed of having a big boss lead the way in person, the research and development was a mess, and when they encountered bottlenecks and difficulties , Qin Yuanqing personally started to solve the problem, and completed the mass production of ultra-high-purity electronic-grade carbon nanotubes in a short period of time, and then the team began to dope-free preparation of high-performance carbon nanotubes (CMOS complementary metal oxide semiconductor) transistors , Polarity control of transistors.

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

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

"Successful! The carbon-based chip was successful!" Professor Pan was so excited that he almost jumped up. Professor Pan, who was almost 48 years old, did not appear stable at this moment.

He never imagined that Qin Yuanqing had been here for less than a month, and the carbon-based chip would be successfully developed. This is simply unbelievable 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 the quantum computer.

"Where is it?" Qin Yuanqing was also quite surprised. He was still thinking that this carbon-based chip might not come out until next year, or even the next year. best news ever.

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

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

Who would have imagined that carbon-based chips were born in their laboratory.

"Academician Qin, thank you, thank you!" Academician Guo's voice was a little choked up.

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

"Look, I'm an old man, I forget when I'm happy, Xiao Cao, take out the carbon-based chip and show it to Academician Qin." Academician Guo said, and then saw a middle-aged man take out a key and unlock the door of the cabinet. Lock it, then put on gloves, and carefully took out a palm-sized brown glass vessel from the sample cabinet.

"Because it is made of carbon material, this chip is more sensitive to strong light sources, so we keep it in it!" Academician Guo explained.

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

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

Qin Yuanqing nodded slightly. The birth of the sample of carbon-based chips means that Huaxia has made a breakthrough from carbon-based transistors to carbon-based chips!
This shows that Huaxia has achieved corner overtaking in the field of carbon-based chips, and it will not be afraid of being stuck again from then on.It also means that the quantum computer has ushered in the most suitable chip for it.

"Academician Guo, Professor Pan, I have almost finished the algorithm, and now only the encryption algorithm is left." Qin Yuanqing said, "I have to return to the capital tomorrow to attend the Nobel Prize awarding ceremony with others. Complete the encryption algorithm."

Before I knew it, it was time for the Nobel Prize award. After Qin Yuanqing came to the University of Science and Technology of China, he also achieved great results. First, it made Huaxia quickly become world-class 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 occupies the first opportunity. It will undoubtedly have a first-mover advantage in the field of carbon-based chips in the future, so it has an absolute right to speak in the formulation of standards. It 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, and a series of tests will be carried out next to test the performance of carbon-based chips and explore related carbon-based chip manufacturing processes. From carbon-based chip laboratory products to commercialization, there is no In three to five years, it is estimated that it is a bit overhanging.

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

This sentence is not outdated until now!

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

In the 3G era, Qualcomm is able to eat a lot of fat. It is not because Qualcomm has mastered the core technology and has a great say in the standard, making it difficult for latecomers to avoid Qualcomm and can only pay Qualcomm taxes honestly.

Therefore, after suffering a lot and paying a lot of tuition fees, Huaxia also began to participate in the formulation of standards to strive for its own best interests.It is because the standard represents the greatest benefit, and the benefit is above the brand.

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

"Okay, then we wish Academician Qin you come back with a cup!" Academician Guo said with a smile: "We must also work hard to re-create a quantum computer and test the performance of carbon-based chips, so as to present a gift to the people of the whole country in the new year!"

Qin Yuanqing smiled, offering a New Year's gift. Domestic scientific research institutions are particularly popular with this, and I don't know what to say. Qin Yuanqing has no special feelings for this tradition, but domestic scientific research institutions always hope to announce the latest results when the Chinese New Year is approaching, and share it with the people of the whole country. Offer a New Year's gift.

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

Qin Yuan smiled lightly and said nothing, in fact, he didn't care if he was reported or not, after all, he was already at the top of the Chinese scientific circles, and he didn't need those fame to add to him, to maintain him right to speak.
