CC, the fastest update material empire!

Qin Haishu is so strong to acquire Nice and renew it back to China. Of course, not only to produce a few IGBT chips to meet Zhou Lin Lei's needs. If so, he is looking for a few pieces to buy a few pieces abroad, where is it? So much money.

He acquired Nice, fundamental purpose is to look at the huge market in IGBT. It is intended to be a cup, to do this, get Nice's equipment and patents just one beginning, there are more things to do.

He first has to solve the problem is based on the original patents of Nice, developed a new generation of IGBT technology, and changing the existing major manufacturers of existing foreign countries.

Nice's patent system is different from Siemens, Toshiba and other large manufacturers, which are suppressed by the technologies of these manufacturers, which is why Nice is in trouble.

Qin Hai knows that in fact, Nice's patents have their own unique, in which the transparent collector area, electric field suspension, carrier storage, and it has become the direction of IGBT technology, but current Nice The company's technicians still cannot recognize the value of these technologies.

Qin Hai has conducted some exchanges in the UK and Nice's engineers. After some ideas, after returning to China, he mixed these ideas with its own brain, the next generation of IGBT technology development direction, The professors of the Semiconductor Center of the Beijing University School of Physics have made a special report.

He is also aware of these semiconductor manufacturing processes, but the idea of ​​more than 10 years in the times, it is simply to provide a guide light for the professors of the Semiconductor Center.

China's semiconductor manufacturing technology is more than ten years behind the West, but the gap in theoretical research is not so big.

Professors are immersed in this field for many years, and the concept of Qin Hai said, they can understand and reach the effect of a non-three.

For a time, various options for improving IGBT have emerged, only waiting for this batch of equipment, and can actually have a production verification.

Light solves the problem of product design, far from enough.

Production equipment is also an important bottleneck, even more important than design.

Qin Hai found the mechanical expert Yue Kun, asked him to lead the "cottage" hosted to introduce equipment

jobs.

It is said that it is a cottage, of course, is not a simple emulation, replication, but to develop its own equipment on the basis of eating foreign equipment principles, develop its own equipment.

The Qingfeng Machinery Group of Daqin Group is based on the original Qingfeng Agricultural Machinery Factory, which has merged the number of mechanical enterprises in Beixi City.

In these years, Qingfeng Machinery Group has imported a large number of precision processing equipment from abroad, has formed a powerful equipment manufacturing capability.

Initially, the main product of the Qingfeng Machinery Group was a hot sprayer. Later, many other material processing equipment were added, including semiconductor manufacturing equipment such as ionic injection machines designed and developed by the Beijing University Physics.

This time, Qinhai Arranging the semiconductor machinery of Yue Kun's comprehensive cottage, Qingfeng Machinery Group is the powerful backing of Yue Kun.

To develop IGBT technology based on almost a white paper, form a mass production capacity, but also to make localization of equipment, this is a ranked project.

However, Tang Rongmin also, Yue Kun, there is no complaint and worry about the responsibility of these tasks, but it is full of fighting spirit and passion.

In their view, the year can do such a career, even how many years is still in this way.

Since the equipment is smuggling from the EU's eyelids, it is not suitable for the big music in a short period of time.

Qin Hai got a relatively remote place in the spring of Pujiang City. As a factory in the semiconductor factory, it took a tiger skin in the middle of the semiconductor factory. From the local military, a guard is adjusted, and the factory is always in the factory. secret.

For this matter, Yu Ming is fully supported, because Zhou Lin Lei introduced him to him, IGBT belongs to the strategic product, there is a large number of applications in the military field, high-power IGBT chip can be mass production, absolutely the improvement of military technology of.

Qin Hai has left after the equipment is unloaded, and this thing is Tang Rongmin, Yue Kun is responsible, and it is not worried about him.

He hurriedly rushed back to Anhe because the School of Materials came out of the news: the graphene study of Nie Sens, has achieved breakthrough progress.

The foregoing has been described, so-called graphene, it is a thin film material composed of a single layer of graphite atom.

Since the thickness is only one atom, it is also known as a "two-dimensional material"

The graphite concept is very clear, but it is not so simple to truly make it.

The earliest inventions of graphite-rare British scientists use "torn tape method"

It is unveiled with a special tape to unveil the graphite layer, and finally reaches only one layer of atom.

This method is prepared as a laboratory, but it is possible to use it for industrial preparation, it is far less than enough, and other methods must be developed.

The idea of ​​developing graphene is, it is raised by Qin Hai to Nien, which is put forward this idea, and he also introduced Niesen by some effective preparation of graphene in the later generation.

These methods include the three categories of solid phase, liquid phase method, gas phase method, each of which includes several small classes, such as oxidative method, organic synthesis method, and chemical vapor deposition in liquid phase method. Method, arc discharge method, etc.

Nie Sen is a nanomaterial expert, which has rich experience in the preparation of nano-grade materials.

After getting the principled guidance from Qin Hai, he led his team with a hard research.

Qin Hai, Wang Xiaochen gave a full guarantee for the funds of Niesen team, so, the money they spent also made Wang Xiaochen to be surprised.

Fortunately, after two years of hard work, Nie Sen finally did not insult the mission, completed the research of two industrial preparation methods, and made a satisfactory success in the small trial.

In this day, in order to avoid the strong Western manufacturers to grab the lead, Nieson's existence of graphene has always been kept, and this important research results are not public.

Until the industrial preparation method has been confirmed, he passed a key paper through an email to the Science Journal, which announced the birth of this magical material to the world.

At the same time as the papers are sent, the Legal Department of Daqin Group has also submitted a patent application for graphene production technology to the US, EU, Japan, and China's patent agencies. A medium-sized enterprise specializing in graphene is also quietly quiet in the Anhe Province. Founded.

Zhou Lin Lei got a notice of Qinhai, even waiting for a number of tickets, directly taking a military aircraft of the Navy, and arrived at Hongze in the first time.

"Qin, what do you say, the lubrication material on the ejector is eyebrow?"

Zhou Linlei stepped into the meeting room of the Materials Institute, and he couldn't wait to ask Qinhai without waiting.

Qin Hai did not mention the concept of graphene in the long-distance call, but he said that he has developed a lubrication material that can be used for aircraft carrier, please come to identify.

Seeing Zhou Lin Lei is eager to look, Qinhai smiled slightly, picking up a small piece of plastic film from the table, handed to Zhou Lin Lei's hand, said: "Zhou Mong, don't worry, you sit down and see This thing is said.

Zhou Lin Lei sat down, took the film, seriously looked at it, and screamed again and found some different.

The thickness of this film seems to have only one third of the usual plastic bag. Zhou Lin Lei can even be able to take it into it.

But when he actually does this, it feels extraordinary, and it is not a real plastic film comparable.

What makes him feel surprised is that when he rubs this film, it has found that it is not a layer, but there are dozens of layers, and the layer and the layers are free to slide, of which there is no gap.

"What is this material?"

Zhou Lin Lei asked, he has realized the extraordinary place of this material. As Qin Hai said, this material is ideal for sealing and lubricating materials as a steam bulge, because it is thin and tough, can withstand repeated Fradrate without wear.

Qin Haidao: "This is a single layer of graphite film, we name it graphene.

The wear-resistant properties of graphite, and wear are very clear. We do this level, should we meet the needs of wear? "

"This also needs experimentation.

Zhou Lin Lei said with cautious attitude, he said, he added another sentence: "However, if this material is graphite material, in my experience, it should be able to meet our needs.

"About its mechanics, thermal performance, we have done a comprehensive test, which is a test report, and we can refer to it.

Qin Hai handed a stack of information to Zhou Lin Lei and said.

Zhou Lin Lei did not hurry to see the relevant data, but asked surprised: "Do you develop this kind of thing, is it as a lubricant?"

"of course not.

Qin Haihun smiled, "Not afraid of you angry, as lubrication materials, but the least important use of graphene is.

This material has excellent electrical energy, and Professor Nie is still testing it, and we have already raised it so far, and each of them is more than a lubricant. More.

"I said.

Zhou Lin Lei did not think that this statement in Qinhai did not respect him. As a senior scientist, he fully imagined that a new two-dimensional electric material came out, will set off how much wind waves in this field.
