While talking about the yellow cake issue, the Orca International Security Company of Wu Gang and others spread out in an orderly manner and was not affected in any way. He was just an international security company. Jurisprudentially speaking, it has nothing to do with the current focus of the issue.
If it matters, it will be in the future. This will undoubtedly give Wu Gang and others enough time to prepare for the arrangement. No matter what the result is, just pull the guy over first and then talk.
Although on the surface, I will never admit that it has anything to do with the recent focus issue, but there is something called hinting, which can hint at the other party's firm attitude, and at the same time hint at the local tyrants. As long as the comprehensive intelligence level of the local tyrants is online, Definitely understandable.
In this way, the local tyrants are also relieved.
……
First Research Institute, Peripheral Core Research Office.
The entire team is divided into several groups, each responsible for the research of different areas, and the leader is Li Linfei, although there is no need to do anything, just keep an eye on it, but after all, these people are not internal robots.
It can be seen that during this period of time, he was really busy, and he had to put aside his love for his children.
At this point in the afternoon, Li Linfei put on a dustproof suit and walked into the material research and development laboratory.
"Director Ye, the experimental data of the two-dimensional tin material has come out." As soon as Li Linfei arrived at the laboratory, the person in charge, Dr. Zhu Feng, came to report excitedly. He was just 30 years old this year.
The 30-year-old Ph.D. can be said to have a bright future. He used to work in the Low-Dimensional Physics and Interface Engineering Laboratory of the Institute of Condensed Matter Physics, Department of Physics and Astronomy, Shanghai Jiao Tong University.
"Have the experimental materials come out?" Li Linfei said simply. He came here today to pick up the materials, and other experimental R&D teams are waiting to conduct experiments.
"A small batch has come out," Zhu Feng said.
"Well, as long as there are materials to use." Li Linfei nodded.
But the young Dr. Zhu Feng is very excited now: "The experimental results show that it is in perfect agreement with the theory you gave. When electrons pass through them, the material will conduct electricity."
"In most other materials, however, the electrons are blocked by impurities or other substances to create resistance, and the resistance heats up, so the electronics need to be cooled to prevent melting."
"But stanene materials can change this situation. The super material of stanene two-dimensional crystal film allows electrons to be emitted along the path without any resistance. The experimental data results show that at a temperature of more than 100 degrees Celsius, a small amount of fluorine is added to stanene. will become zero resistance."
The development of the super material stanene is led by Zhu Feng, who is very clear about the changes it will bring to the world.
Stanene was actually designed by Zhang Shoucheng, and scientists call this material a topological insulator.
Stanene is internally insulated and externally conductive. The stannene layer or a tin plate with an atomic thickness basically means that the entire surface circuit can reach 100%.
In general, this super material has more potential than the fiery graphene that is hyped on the market, and stanene seems to be a niche at present.
But not only can it be used as a cheap and abundant material to replace silicon in the manufacture of computer chips, its atomic-thick circuit connections that don't heat up allow designers to further miniaturize electronic devices.
The size of chip components made of stanene materials can be reduced to one-fifth or even one-eighth of the current size, and energy consumption can be reduced by 90-98%. It is foreseeable that the birth of tin chips will definitely improve the current processing performance The mediocre growth of the chip industry has brought unprecedented explosive power.
In the clean room on the inner floor of the laboratory, two staff members carefully sealed up a small batch of stanene two-dimensional crystal films and took them out.Then put it into a sealed box, and passed it out of the inner clean room to Li Linfei, who said, "How far is the purification?"
Zhu Feng replied affirmatively: "The technology you provided is used, and the purification reaches 99% with nine nines behind the decimal point."
Dian Li Linfei explained: "Get ready to finalize the shape, the sooner the better, after the finalization is completed, the tin material will be mass-produced immediately."
Zhu Feng nodded, but he was startled and hurriedly said, "What? It will be mass-produced soon? However, there is still one last experiment that has not been verified. Although the epitaxially grown stanene film is extremely stable, we have not yet To determine how long its superconductivity can last, of course, Mr. Li, I have no doubts about the theoretical data you gave, but I just think it is better to be cautious."
Obviously, Zhu Feng is still very worried. Although what he said is more euphemistic, after all, once mass production will cost billions of billions of dollars, if the product is not up to standard after testing in the future, the loss will be immeasurable. Mass recalls and impact on brand reputation.
Li Linfei, who was about to leave, looked back at him: "I can't give you a few years to test its reliability. Scientific research does need to be cautious, but sometimes it's done first."
Zhu Feng hesitated to speak, Li Linfei added: "PHC now only has 1400 million pieces in stock, and this is only because the business in the overseas market has been terminated and the supply is only for the mainland. You can return to the overseas market in the future, but at the same time, the mainland market is also out of stock, thousands of factories will close down, and tens of thousands of people will face unemployment. Do as I say, and I will take responsibility for things that happen. I am the general manager. principal."
"Okay, I understand." After Li Linfei said that, Zhu Feng had no choice but to carry it out.
Facts have proved that even the person who cheats is still a person after all, not a god.
Li Linfei has a lot of epoch-making knowledge in his mind, but to turn the knowledge in his mind into a real product, he needs the assistance of a reliable team to realize it, and some advanced technologies will cause big troubles instead. Just say that seawater desalination technology has caused so many troubles.
The first thousand and ninety-eight chapters succeeded
As time passed, Li Linfei led the entire semiconductor team to intensively engage in large-scale technology development. The results accumulated over time, and the interview for new products was about to begin.
A week later, around 11 am, a convoy of three or five vehicles arrived at the R&D room of the First Research Institute, and the person in charge of the R&D center came out to greet the convoy when it arrived.
Because the person who came was Li Linfei.
"Mr. Li, have the tin sheet materials arrived?" the person in charge said impatiently.
Hearing this, Li Linfei looked sideways at a man who was following him, and motioned for a precision airtight box in his hand. The other man saw Li Linfei's gaze and immediately handed over the airtight box in his hand. The man from the R&D center The person in charge suddenly brightened his eyes, and immediately urged the accompanying assistant to take it over, not forgetting to say: "Xiao Xiaodian, this is a treasure!"
"Team Leader Huang, how are your preparations going?" Li Linfei asked.
"It's been prepared a long time ago, and I've been waiting for three days, just waiting for the tin sheet." Team leader Huang said bluntly.
"Then what are you waiting for? Let's get started."
"Mr. Li, please!"
In the outlying research room of the First Research Institute, a large laboratory closed the anti-theft tempered glass door. When Li Linfei and others approached about three to five meters away, there was a chirping sound, and the glass door suddenly opened by itself.
At this time, Li Linfei, the person in charge of the R&D center and an important person in charge of China Microelectronics came to the laboratory together, and various instruments and equipment were immediately exposed to everyone's vision, especially in the center of the laboratory. In terms of location, a device with a height of more than four meters and a matrix structure is particularly eye-catching.
There were several young engineers in the laboratory, and Li Linfei, who was wearing a dust-free suit, did not ask the person in charge of the R&D department for instructions, and went directly to the battle, and said to the engineers: "Don't be dazed, let's start. "
They get to work right away.
Li Linfei skillfully turned on this lithography machine, which was completely independently developed by domestic components, and a cone-shaped funnel-shaped instrument suddenly appeared inside, and the instrument was hooked on the top.
Cables about two fingers wide are densely covered, and the outer layer of copper wires is surrounded by layers. Inside the exposed body, thousands of parts are densely aligned and linked together to form a precise miniaturized closed structure. The view from a close distance is very spectacular.
Li Linfei commanded five engineers who assisted him to carry out the final debugging operation. A staff member took the sealed box he brought and took out the stanene two-dimensional wafer from it, which is the fabricated tin wafer.
The manufacturing process of the chip is very complicated. First, it provides high-purity stanene two-dimensional crystal film. After absorbing the core technology of raw material technology, the purity of the stanene material is also improved to the world's top level.
It is worth mentioning that in addition to a lithography machine, an etching machine is also needed to make a chip. If the lithography machine is the soul of chip manufacturing, then the etching machine is the soul of chip manufacturing. If you want to make a real high-end process chip , both of which must be top-notch.
Prior to this, the development of domestic lithography machines and etching machines was very embarrassing, which was a serious partial situation. China Microelectronics has been able to carry out mass production of 5-nanometer level etching machines, and has directly entered the world's leading ranks without any suspense. Quantum The etching machine is also in the experimental stage, which is the result without Ye Hua's help.
However, whether it is the 90-nanometer lithography machine of Microelectronics or the 200-nanometer lithography machine of Shadow Speed, the lithography machine companies are far behind the most advanced 5-nanometer process of ASML in the world.
These two machines and equipment, simply put, is that the lithography machine projects the circuit diagram onto the silicon wafer covered with photoresist, of course, it is now a tin sheet, and the etching machine etches away the redundant circuit diagram on the chip with the circuit diagram drawn.
This does not seem to be difficult, but there is a vivid metaphor, the circuit mechanism on each chip is magnified countless times, and it is several times more complicated than the whole. This is the difficulty of lithography machines and etching machines.
The process of photolithography is to coat the surface of the finished tin circle with a layer of photoresist. The so-called photoresist is a colloidal substance that can be corroded by light, and then mapped to the tin circle by extreme ultraviolet light through the mask Surface, similar to projection.
Because of the coverage of photoresist, the irradiated part will be corroded, and the part without light will be left. This part is the required circuit structure.
The lithography function of the lithography machine is similar to that of a camera. The working principle is to expose the circuit diagram of the chip route and function through a photomask with a pattern to expose the wafer coated with the lithography machine chip, and the photoresist will change in nature after exposure to light. , so that the circuit obtained on the photomask is copied onto the chip wafer.
To put it vividly, it is like the flat printing process. Once the architectural plan is determined, as long as the raw materials are sufficient, the heavy-duty production will be over.There are two etching methods, one is dry etching and the other is wet etching. This time, AMEC provides the second etching solution.
