Qin Haihua spent so much effort to acquire Nice Company and dismantle it back to China, of course, not only to produce a few igbt chips to meet Zhou Linlei's needs. If so, he could just find someone to purchase a few chips abroad. Where can he spend the money?
So much money. The fundamental purpose of his acquisition of Nice Company is to take a fancy to the huge igbt market and plan to get a share of it. To do this, obtaining Nice Company's equipment and patents is just the beginning, and there will be more to come.
Things to do.
The first problem he has to solve is to develop a new generation of igbt technology based on Nice Company's original patents to compete with the existing major foreign manufacturers. Nice Company's patent system is different from that of large manufacturers such as Siemens and Toshiba.
Being suppressed by the technologies of these large manufacturers is the reason why Nice Company is in operating difficulties. Qin Hai knows that Nice Company's patent actually has its own unique features, including transparent collector area, electric field interruption, current carrying
Ideas such as sub-storage later became the direction of igbt technology breakthroughs, but the technical staff of Nice Company are still unable to realize the value of these technologies.
Qin Hai had some exchanges with engineers from Nice Company in the UK and learned some of their ideas. After returning to China, he mixed these ideas with what he had in his mind about the development direction of the next generation IGBT technology, and presented it to him.
Professors from the Semiconductor Center of the School of Physics at Kyungseong University gave a special report. He actually knew little about these semiconductor manufacturing process issues, but those ideas that were nearly 10 years ahead of the times were simply nothing to the professors of the Semiconductor Center.
Provides a guiding light.
China's semiconductor manufacturing technology lags behind the West's by more than ten years, but the gap in theoretical research is not that big. The professors have been immersed in this field for many years, and they can immediately understand some of the concepts Qin Hai said, and
Achieving the effect of drawing inferences from one example. For a time, various plans to improve igbt continued to emerge. Just waiting for this batch of equipment to be in place, actual production verification can be carried out.
It is not enough to solve the problem of product design alone. Production equipment is also an important bottleneck, even more important than design. Qin Hai invited Yue Kun, a mechanical expert, to lead the "copycat" of imported equipment.
Work. To say it is a copycat, of course, is not to simply imitate and copy, but to develop your own equipment based on a thorough understanding of the principles of foreign equipment and combined with new semiconductor processing theories.
Qingfeng Machinery Group, a subsidiary of Daqin Group, was formed based on the original Qingfeng Agricultural Machinery Factory and the merger of several machinery companies in Beixi City. In recent years, Qingfeng Machinery Group has imported a large number of precision processing equipment from abroad.
, has formed a strong equipment manufacturing capability. Initially, Qingfeng Machinery Group’s main product was thermal spraying machines, and later added many other material processing equipment, including an ion implanter designed and developed by the School of Physics of Kyungseong University
Waiting for semiconductor manufacturing equipment. This time Qin Hai arranged for Yue Kun to completely imitate foreign semiconductor machinery, and Qingfeng Machinery Group was Yue Kun's strong backing.
It is a large-scale project to independently develop igbt technology on the basis of almost a blank sheet of paper, form mass production capabilities, and also achieve localization of equipment. However, whether it is Tang Rongmin or Yue Kun,
They have no complaints or worries about undertaking these tasks. Instead, they are full of fighting spirit and passion. In their view, they will not hesitate to do such a career in their lifetime, even if they lose a few years of life for it.
Since the equipment was smuggled back from under the nose of the European Union using extraordinary means, it was not suitable for publicity in the short term. Qin Hai found a relatively remote place on the outskirts of Pujiang City as the site of the semiconductor factory.
With the tiger skin of Ji Mingchu, a guard platoon was transferred from the local military to be stationed around the factory to protect the secrets of the factory. Ji Mingchu fully supported this matter because Zhou Linlei introduced to him that igbt belongs to
Strategic products also have a large number of applications in the military field. The mass production of high-power IGBT chips will definitely be of great benefit to the improvement of military technology.
Qin Hai left after watching the equipment being unloaded. Tang Rongmin and Yue Kun were in charge of things here, so he didn't need to worry too much. He hurried back to Anhe because there was good news from the School of Materials:
Graphene research led by Nie Sen has made breakthrough progress.
As mentioned before, graphene is simply a thin film material composed of a single layer of graphite atoms. Because its thickness is only one atom thick, it is also called a "two-dimensional material". The concept of graphene
It's very clear, but it's not that simple to actually make it. The British scientist who first invented graphene used the "tearing tape method", which uses a special tape to peel off the graphite layer by layer.
Eventually, it reaches the point where there is only one layer of atoms. This method is feasible as a laboratory preparation, but it is far from enough for industrial preparation, and other methods must be developed.
The idea of developing graphene was proposed by Qin Hai to Nie Sen. While proposing this idea, he also introduced to Nie Sen some effective methods for preparing graphene in later generations. These methods include solid phase method,
There are three major categories: liquid phase method and gas phase method. Each major category contains several subcategories, such as redox method in liquid phase method, organic synthesis method, chemical vapor deposition method in gas phase method, arc discharge method, etc.
.
Nie Sen was originally a nanomaterials expert and had extensive experience in the preparation of nanoscale materials. After receiving principled guidance from Qin Hai, he led his team to carry out arduous research. Qin Hai told Wang Xiaochen to Nie Sen
The team's financial expenditures were fully guaranteed. Even so, Wang Xiaochen was frightened by the money they spent. Fortunately, hard work paid off. After more than two years of hard work, Nie Sen finally fulfilled his mission and completed two industries.
Research on preparation methods and achieved complete success in small trials.
Previously, in order to avoid being seized by powerful Western manufacturers, Nie Sen had remained silent about the existence of graphene and did not make this important research result public. It was not until the industrial preparation method had been confirmed that he passed the electronic
A key paper was submitted to a private journal by 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 also submitted submissions to the patent agencies of the United States, the European Union, Japan and China.
After applying for a patent for the graphene production process, a medium-sized company specializing in the production of graphene was quietly established in Cen Chau City, An Ho Province.
After Zhou Linlei received Qin Hai's notice, he didn't even wait for the estimated air ticket. He directly took a navy military plane and rushed to Hongze as soon as possible.
"Mr. Qin, what are you talking about? Is there any clue about the lubricating material on the catapult?" Zhou Linlei strode into the conference room of the School of Materials Science and Technology. Before sitting down, he couldn't wait to ask Qin Hai. Qin Hai didn't mention it on the long-distance call.
As for the concept of graphene, he just said that he had developed a lubricating material that could be used in aircraft carrier steam catapults and asked him to come and 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, handed it to Zhou Linlei's hand, and said: "Gong Zhou, don't be anxious, sit down and take a look first.
Let’s talk about this later.”
Zhou Linlei sat down, took the piece of film, looked at it carefully, and twisted it with his hands, and found something strange. The thickness of this film seemed to be only a fraction of that of an ordinary plastic bag. Zhou Linlei was even worried that if he lightly
He could pierce it with force. But when he actually did this, he felt that its toughness was extraordinary, far from being comparable to real plastic film. What surprised him even more was that when he rubbed the film,
It was discovered that it was not one layer at all, but had dozens of layers. The layers could slide freely between layers, and there were no gaps at all.
"What substance is this?" Zhou Linlei asked in surprise. He had already realized the extraordinary features of this material. As Qin Hai said, this material is very suitable as a sealing and lubricating material for steam catapults because it is instant
Thin and tough, it can withstand repeated friction without wear.
Qin Haidao: "This is a single-layer graphite film. We named it graphene. Zhou Gong is very clear about the wear-resistant properties of graphite. If we can achieve this level, it should be able to meet Zhou Gong's needs, right?"
?”
"This still needs to be tested." Zhou Linlei said with caution. After that, he added: "However, if this material is graphite, based on my experience, it should be able to meet our needs.
."
"We have conducted comprehensive tests on its mechanical and thermal properties. This is the test report. Zhou Gong can refer to it." Qin Hai handed a stack of information to Zhou Linlei and said.
Zhou Linlei was not eager to see the relevant data, but asked in surprise: "You developed this kind of thing just to use it as a lubricating material?"
"Of course not." Qin Hai laughed, "I'm not afraid of your anger. As a lubricating material, graphene is the least important use. This material has excellent electrical properties. Professor Nie's laboratory is still working on it.
It has been tested, and the uses we have proposed so far are no less than 100, each of which is much more valuable than being used as a lubricating material."
"That's what I said." Zhou Linlei didn't feel that Qin Hai's statement was disrespectful to him at all. As a senior scientist, he could fully imagine that the advent of a new two-dimensional electrical material would have a huge impact on this field.
