Material Empire

Qin Haihua made such a great effort to acquire the Nice company and dismantle it back to China, of course, not only to produce a few pieces of igbt chips to meet the needs of Zhou Linlei, if so, he would find someone to buy a few pieces abroad, and where can he spend So much money. The fundamental purpose of his acquisition of Nice is to see the huge market of igbt, and he intends to take a share of it. To do this, obtaining the equipment and patents of Nice is only the beginning, and there is more to be done later.

The first problem he had to solve was to develop a new generation of igbt technology based on the original patent of the Nice company, and to fight against the existing major manufacturers in foreign countries. The patent system of Nice is different from that of Siemens, Toshiba and other large manufacturers. It is suppressed by the technology of these large manufacturers, which is why the company is in trouble. However, Qin Hai knew that in fact, the patents of the Nice company were unique. The ideas about transparent current collection areas, electric field suspension, and carrier storage all became the direction of igbt technology breakthrough. The company's technical staff is not yet aware of the value of these technologies.

Qin Hai had some exchanges with engineers in Nice in the UK and learned some of their ideas. After returning to China, he mixed these ideas with the content of the next-generation igbt technology development in his mind. Professors from the Semiconductor Center of the School of Physics, Jingcheng University made a special report. He is also ignorant of these semiconductor manufacturing processes, but those thoughts that are nearly 10 years ahead of the times, for the professors of the Semiconductor Center, simply provide a guiding light.

China's semiconductor manufacturing technology is more than ten years behind the West, but the gap in theoretical research is not so great. Professors have been immersed in this field for many years, and Qin Hai expressed some ideas. They can understand immediately and achieve the effect of inferiority. For a while, various programs to improve igbt continued to emerge. Just waiting for this batch of equipment to be in place, the actual production verification can be carried out.

Solve the problem of product design. It's not enough. Production equipment is also an important bottleneck, even more so than design. Qin Hai brought in Yue Kun, a mechanical expert, and asked him to lead the work on the “copycat” of the imported equipment. To say that it is a cottage, of course, it is not a simple imitation test and copy, but to develop new equipment based on a thorough understanding of foreign equipment principles, combined with new semiconductor processing theories.

Qingfeng Machinery Group under Daqin Group is based on the original Qingfeng Agricultural Machinery Factory. It was formed by the merger of several machinery enterprises in Beixi City. In recent years, Qingfeng Machinery Group has imported a large number of precision processing equipment from abroad, and has formed a strong equipment manufacturing capability. Initially, the main product of Qingfeng Machinery Group was a thermal sprayer. Later, many other material processing equipment were added, including semiconductor manufacturing equipment such as ion implanters designed and developed by the School of Physics of Jingcheng University. This time Qin Hai arranged Yue Kun to fully copy foreign semiconductor machinery, and Qingfeng Machinery Group was the strong backing of Yue Kun.

It is a large-scale project to independently develop IGBT technology on the basis of almost a piece of white paper, to form the ability to mass-produce, and to localize equipment. but. No matter Tang Rongmin and Yue Kun, there are no complaints or concerns about taking on these tasks. Instead, it is full of fighting spirit and passion. In their opinion, it is not unreasonable to be able to do such a career in their lifetime, even if they have not lived for that many years.

Since the equipment was smuggled back from the eyelids of the European Union by extraordinary means, it was not suitable for publicity in a short period of time. Qin Hai found a relatively remote place on the outskirts of Pujiang City. As the site of the semiconductor factory, he also pulled tiger skins from the early Ming Dynasty. He transferred a guard platoon from the local military to stay around the factory to protect the factory. secret. For this matter. Ji Mingchu fully supported it because Zhou Linlei introduced it to him. IGBT is a strategic product and has a large number of applications in the military field. The mass production of high-power igbt chips is definitely beneficial to the improvement of military technology.

After seeing the equipment and unloading the ship, Qin Hai left. Tang Rongmin and Yue Kun were in charge of things here, so he didn't have to worry too much. He hurried back to Anhe because of a good news from the School of Materials:

The graphene research chaired by Nie Sen has made breakthrough progress.

As mentioned earlier, the so-called graphene is simply a thin film material composed of a single layer of graphite atoms. Because it is only one atom thick, it is also called a "two-dimensional material." The concept of graphite is clear, but it is not so simple to actually make it. The earliest British scientists who invented graphite thinner used the "tear tape method". A special tape was used to peel the graphite layer by layer, and finally reached the level of only one layer of atoms. This method is feasible as a laboratory preparation, but it is not enough for industrial preparation, and other methods must be developed.

The idea of ​​developing graphene was put forward by Qin Hai to Nie Sen. While presenting this idea, he also introduced some effective methods for preparing graphene in later generations to Nie Sen. These methods include solid phase method, liquid phase method, and gas phase method, each of which includes several small categories, such as redox method in liquid phase method, organic synthesis method, and chemical vapor deposition in gas phase method. Method, arc discharge method and so on.

Nie Sen was originally a nanomaterials expert and has extensive experience in the preparation of nanoscale materials. After receiving Qin Hai's principled guidance, he led his team to carry out difficult research. Qin Hai explained that Wang Xiaochen gave full protection to the expenses of Nie Sen's team. For this reason, the money they spent also made Wang Xiaochen frightened. Fortunately, time is spent, and after more than two years of hard work, Nie Sen finally fulfilled his mission, completed the research on two industrial preparation methods, and achieved great success in the small test.

Previously, in order to avoid being seized by powerful Western manufacturers, Nie Sen kept silent on the existence of graphene and did not make this important research result public. It wasn't until the industrial preparation method was confirmed that he submitted a crucial paper to the journal via email, announcing the birth of this magical material to the world. At the same time as the paper was sent, the legal department of Daqin Group submitted patent applications for graphene production processes to patent agencies in the United States, the European Union, Japan, and China. A medium-sized company specializing in graphene was quietly located in Cenzhou City, Anhe Province. Founded.

Zhou Linlei was notified by Qin Hai that he couldn't even wait for the expected flight ticket and took a navy military aircraft directly, and arrived in Hongze in the first time.

"Mr. Qin, what are you talking about? The lubricating material on the catapult is brow eyebrows?" Zhou Linlei strode into the conference room of the Materials College, and couldn't wait to ask Qin Hai. Qin Hai did not mention the concept of graphene in the long-distance call, but said that he had developed a lubricating material that could be used in the aircraft carrier's steam ejector, and he asked him to identify it.

Seeing Zhou Linlei's anxious look, Qin Hai smiled slightly, picked up a small piece of plastic film-like thing from the table, and handed it to Zhou Linlei's hand, saying, "Zhou Gong, don't worry, you sit down and take a look Let's talk about this thing. "

Zhou Linlei sat down, took the film, looked at it carefully, twisted it by hand, and found something strange. This film seems to be only a fraction of the thickness of an ordinary plastic bag. Zhou Linlei even worried that he could pierce it with a little force. But when he actually did this, he felt that its toughness was extraordinary, far from being comparable with a real plastic film. What surprised him even more was that when he rubbed the film, he found that it was not a layer at all, but dozens of layers. The layers could slide freely without any gaps.

"What is this substance?" Zhou Linlei asked in surprise, he had realized the extraordinaryness of this material, as Qin Hai said, this material is very suitable as a sealing and lubricating material for steam ejectors, because it is Thin and tough, able to withstand repeated friction without wear.

Qin Haidao: "This is a single-layer graphite film, we named it graphene. The abrasion resistance of graphite is very clear for Zhou Gong, and we can achieve this level ~ www.novelmtl.com ~ Does Zhou Gong need it? "

"This requires experimentation." Zhou Linlei said cautiously, adding that he added: "However, if this material is a graphite material, in my experience, it should be able to meet our needs. . "

"We have done a comprehensive test of its mechanical and thermal properties. This is a test report. Zhou Gong can refer to it." Qin Hai passed a stack of information to Zhou Linlei, saying.

Zhou Linlei was not eager to look at the relevant data, but asked in amazement: "Do you develop this kind of thing as a lubricant?"

"Of course not." Qin Hai grinned, "I'm not afraid of you being angry, as a lubricant, but the least important use of graphene. This material has excellent electrical properties, and Professor Nie's laboratory is still working on It is tested, and there are no less than 100 uses we have proposed so far, each of which is much more valuable than a lubricating material. "

"I said." Zhou Linlei did not feel that Qin Hai had any disrespect to him. As a senior scientist, he could fully imagine that the advent of a new two-dimensional electrical material would be in this field. How big a storm is here. (To be continued)
