Not many people know the encrypted email address of “Mr.

Every month, I will post the latest optimization progress of EDA and some difficult problems encountered. Qin Ke will give me some pointers when I see it.

In addition, there is Cai Mingzhi, deputy chief engineer of the "chip materials" team.

The sender of today’s email is Cai Mingzhi.

Because Xu Qingyan is in charge of all aspects, it is difficult for him to have the time and energy to follow up the technical work of a certain research group. And the chief engineer of the "Chip Materials" team, He Yisheng, is still hospitalized, so the daily technical work of "Chip Materials" has fallen behind.

It came to the head of Deputy Chief Engineer Cai Mingzhi.

Cai Mingzhi is a typical deputy character. He is a bit indecisive but has strong execution ability.

Although he was very troubled when "Mr. Q" overturned the technical direction of carbon nanotube field-effect transistors that the previous team had spent countless efforts and efforts researching, he still firmly led the team to implement "Mr. Q" when it came to work.

"A new direction for research and development of new chip materials proposed.

Qin Ke quite recognized this Cai Gong.

This time, Cai Gong sent not only a routine work report, but also raised a problem that had nothing to do with technology, and wanted to ask Mr. Q if he could solve it.

Cai Gong wrote in the email: "You also know that the synthesis research of nanomaterials is inseparable from high-end experimental equipment, but currently our team's material measurement and control equipment and angle-resolved photoelectron spectroscopy, electron energy loss spectroscopy, and molecular beam epitaxy growth,

Scanning tunneling microscopes cannot meet the requirements of the experimental plan you envisioned. As far as we know, the only laboratories in China that meet our experimental conditions for such high-end material research are NTU's 'Ultracold Atom Quantum Laboratory' and

The 'Green Lemon Quantum Computing Laboratory' in Beijing. Director Xu and I have made many requests to rent equipment from these two laboratories, but have been declined. Mr. Q, can you think of any ideas?"

Qin Ke couldn't laugh or cry. If he hadn't known that Cai Gong didn't know the true identity of "Mr. Q", he would have doubted whether this guy had deliberately sent emails to "blackmail" him.

Qin Ke is not familiar with NTU's "Ultracold Atom Quantum Laboratory", but the "Ling Ning Quantum Computing Laboratory" was opened by him and Ning Qingyun.

As for the "Green Lemon Quantum Computing Laboratory" rejecting Cai Mingzhi's request to rent equipment, it is completely normal. The "30mK ultra-low temperature strong magnetic field scanning tunneling microscope system" was finally obtained by Qin Ke after a lot of effort.

The laboratory itself treasures the precious equipment imported from China and is reluctant to use it frequently to avoid parts wear and tear, so how can it be rented to others?

Moreover, the confidentiality regulations of the "Green Lemon Quantum Computing Laboratory" are very strict, and it is impossible to allow equipment to be loaned out, or to allow outsiders to enter the laboratory to borrow equipment for experiments.

NTU’s “Ultracold Atom Quantum Laboratory” is estimated to be in a similar situation.

Qin Ke rubbed his forehead. Cai Gong's "chip materials" team and his own "quantum topological superconducting materials" team had a conflict at this time, which was indeed not easy to resolve.

This is not the first equipment-related problem encountered by the "Chip Materials" team.

Although the systematic S-level knowledge "Full Process of Manufacturing a New Type of Carbon Crystal Composite Nanomaterial Suitable for 1nm Chips" records very detailed material synthesis and the entire manufacturing process, having the "drawings" does not mean that it can be

Easily produced, especially this type of "carbon crystal composite nanomaterial" that is beyond the current era, requires very high precision requirements for experimental equipment.

Don't look at the "Qingbei Integrated Circuit and Chip Joint R&D Innovation Center" as a relatively advanced national key chip research laboratory in China. In fact, most of its experimental equipment was moved from Qingmu University and Beiyan University. A small part

They are obsolete products purchased from domestic chip fabs.

There is a big gap between domestic chip research and development equipment compared to foreign countries. How can these old models and obsolete products meet the research and development needs of "carbon crystal composite nanomaterials"?

Therefore, Qin Ke's biggest headache is not how to "reasonably" research "carbon crystal composite nanomaterials", but how to use the current experimental equipment and try every means to slowly produce "carbon crystal composite nanomaterials" through experiments.

During the research on chip materials in the first two or three months, we encountered similar problems of substandard experimental equipment several times.

It is impossible to purchase from abroad. Even if you want to bite the bullet and pay several times the premium to buy a second-hand equipment, it is also an impossible task. Even if a foreign company or laboratory is willing to sell it, it cannot be shipped back, especially

For this type of high-end experimental equipment, the transportation needs to be handled by a professional company, otherwise it may turn into scrap metal after a collision - so it is impossible to purchase it through unconventional methods.

Qin Ke had called Uncle Yang Chengke several times, and asked big shots like Uncle Yang to come forward, so he borrowed some parts from some major chip manufacturers and other national key research institutes on the grounds of "emergency."

Laboratory equipment.

Fortunately, this time, it was his own "Lime Quantum Computing Laboratory"'s turn.

The problem is that the "Ling Ning Quantum Computing Laboratory" is also in full swing on the research and development of "Ling Ning Superconducting Material No. 2". If the "30mK ultra-low temperature strong magnetic field scanning tunneling microscope system" is lent, this subject will have to be

Stopping for two or three years...the price is too high.

One is a new chip material that allows Xia Guo to easily suppress the international mainstream 5nm silicon-based chips with 14nm chips and even future 2nm and 1nm silicon-based chips. The other is related to the realization of future billion-level quantum computing, making it possible for quantum computers to enter thousands of homes.

Wanhu's topological superconducting materials can be said to be like flesh on the palm of the hand and on the back of the hand.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Qin Ke frowned after reading the list of high-end equipment requirements sent by Cai Mingzhi. In addition to high-precision optical observation instruments such as scanning electron microscopes, there is also a shortage of nanometers.

There are more than a dozen equipment including non-destructive testing instruments for materials. Cai Gong said that some of the equipment has not even been heard of being owned by any domestic laboratory.

After pacing back and forth in the study for a while, Qin Ke slapped his forehead and asked, "Why does he have a headache? If you need anything, please see Uncle Yang."

How could Cai Mingzhi’s sources of information be as good as Uncle Yang?

Qin Ke took out a special mobile phone given to him by Wei Feng - it was said that it was a satellite phone, using a special encrypted line and could not be monitored - and then called Uncle Yang to inform him of the matter.

Uncle Yang nodded happily and said: "Don't worry, I will take care of this matter. I probably know where to find these equipment." He pondered for a moment and then said: "Qin Ke, do you estimate how long it will take for the 'carbon crystal composite nanomaterials' to be produced?"

Will it be researched and confirmed within three years?"

"The key is to look at the experimental equipment. If you have enough experimental equipment, it will be faster. If you don't have it, you will have to think of other ways, and the progress will be much slower." Qin Keli knew the meaning and asked curiously: "Uncle Yang, someone is slandering you in front of you.

?”

"You are just talking about 'slander', you kid." Uncle Yang smiled and cursed, and said: "Only your senior brother Xu's 'chip material' team knows about the research on 'carbon crystal composite nanomaterials', and outsiders don't know. Who would make such slanderous remarks?"

?The situation is like this. A chip materials research laboratory at NTU recently submitted a funding application. Attached is the latest research progress on carbon-based chip materials. To be honest, it is obvious from the report they submitted.

The prospect is very attractive. No one here except me knows about the 'carbon crystal composite nanomaterial', so they are all inclined to vigorously support this 'carbon-based chip material' in terms of scientific research funding next year."

Qin Ke understood as soon as he heard that the cake was so big, and everyone wanted to get more research funds. Naturally, competition in this area was fierce. After all, if one company gets more, the other will naturally get less.

Senior Brother Xu Qingyan's "Qingbei Integrated Circuit and Chip Joint R&D Innovation Center" is by no means the only national-level chip R&D center in China. Nanda is extremely famous in this regard, and its results are no worse than those of Qingmu and Yanda.

Now in order to keep the secret of “Mr.

"Field Effect Transistor Technology Direction". Huge funds have been burned in this direction for several years, but there are no achievements worth showing off. Naturally, there will be dissatisfaction from the upper levels.

Uncle Yang was unable to speak out on such a major financial matter.

"Uncle Yang, I'm a little curious about what kind of blueprint is described in NTU's report on 'carbon-based chip materials'?"

It would be inappropriate for Qin Ke to ask such questions from the standpoint of the "Qingbei Integrated Circuit and Chip Joint R&D Innovation Center". However, he has a transcendent status. Now, as "Mr. Q", he is only guiding the "chip materials" team on a purely voluntary basis.

That’s all, there is no name in the team either internally or externally, and there is no financial interest.

Naturally, Yang Chengke would not hide anything from Qin Ke, whom he trusted the most. He picked up the report on his desk and said:

"What they are studying is 'graphene-carbon nanotube special-shaped structure technology', which is simply a technology in which graphene is used as the main raw material to form carbon nanotubes, and is distributed and arranged to form a unique T-shaped special-shaped crystal integrated circuit.

According to them, the conductivity is 53% higher than that of traditional silicon-based chips, and the energy consumption is reduced by 30%. One of its biggest advantages is that the process technology requirements of the photolithography machine are not high. The carbon produced using the 90nm process

The performance of the base chip is equivalent to that of a 28nm silicon-based chip; while the carbon-based chip using 28nm is equivalent to a 7nm silicon-based chip."

Qin Ke nodded slightly. Judging from the literal report, it is indeed remarkable. Carbon-based chips produced using 28nm lithography can achieve the same effect as silicon-based chips produced by the world's mainstream advanced lithography machines. Even if it is placed internationally,

It's quite advanced.

Especially at present, although Xia Guo has conquered the FinFET technology of the 14nm process and ensured high-quality product output, in terms of lithography machines, Xia Guo has a larger number of 28nm process lithography machines and 14nm process lithography machines.

There is still a very tight shortage, and currently domestic chip manufacturers are mainly focusing on the 28nm process.

It can be said that NTU’s report and prospects are very in line with the current situation of Xia State and are very attractive.

In fact, using carbon nanotubes as a breakthrough, the development of carbon-based chips is also a popular direction in the world. Because carbon-based chips have higher carrier mobility, are more suitable for high-speed computing, have better thermal conductivity, are lighter, etc.

Advantages. Another advantage of carbon-based chips is that they can be prepared through chemical methods, and the production cost is lower than that of silicon-based chips.

There are not even 1,000 but 800 related research teams in the world. The "Carbon Nanotube Field Effect Transistor Technology Direction" that the "Chip Materials Team" has been studying belongs to one of these branches. The only ones that have made significant progress so far are

Those two or three top chip manufacturers abroad.

Of course, in Qin Ke's eyes, carbon-based chips are not the best choice in the non-quantum era. Chips made of "carbon crystal composite nanomaterials" are the optimal solution. It is also a 28nm "carbon crystal composite nanomaterial"

The chip can easily outperform 2nm silicon-based chips, comparable to the rumored 1nm silicon-based chips. Carbon-based chips have no cost performance compared to "carbon crystal composite nanomaterial" chips.

However, Qin Ke was still curious about the level of domestic chip material technology, so he asked: "Have they said how long it will take to develop a 28nm carbon-based chip?"

Uncle Yang frowned: "The report is very beautifully written. According to them, they have basically mastered the key technical principles of the research. It is possible to develop a carbon-based chip prepared by the 90nm process in the laboratory within three years.

And within five years, they have broken through the carbon-based chip technology prepared by the 28nm process. They are relatively high-profile in the media, and they also have technical exchanges and cooperation with foreign countries. Anyway, I think it is a bit unreliable. Only a few of their actual scientific research results have been published in China.

Papers in core journals, as well as some carbon nanotube materials that look a bit weird. But many people are impressed by the blueprint they drew, and next year's funding is likely to be heavily tilted towards them."

"Qingbei Integrated Circuit and Chip Joint R&D Innovation Center" is not like Qin Ke's Quantum Computing Laboratory. It has the financial backing of Qingning Technology, so it has no worries about research funding. If the scientific research funding is significantly reduced, "Qingbei Integrated Circuit and Chip Joint R&D Innovation Center"

The "Beijing Integrated Circuit and Chip Joint R&D Innovation Center" will soon be stretched thin. "Gold-eating beasts" like the "Chip Materials" team, let alone borrowing high-end precision experimental equipment and conducting frequent experiments, will be questionable as to whether they can maintain ordinary experimental research.

.

Qin Ke thought for a while and asked: "Uncle Yang, can I sit in your office and take a look at these reports and the carbon nanotube material?"

"you mean?"

"Your judgment just now made me a little curious." Qin Ke's eyes flashed and he said in a condensed voice: "I also want to take a closer look at the level of the so-called top domestic chip materials. If these reports and research results are

It's true. I think we can focus on supporting domestic chip research. My Qing Ning Technology can provide half of the scientific research funding for Senior Brother Xu's 'chip materials' team. But if these reports and research results have
