Material Empire

Zhou Linlei ran to Anhe to work as a temporary chief engineer for Hongze Motor Factory, and helped Qin Hai sing a drama pit for Liu Xuping, all because Qin Hai promised to solve the technical problems related to the aircraft carrier catapult for him. Now that he has done all the things he should do, it is time to ask Qin Hai to give back.

"General Manager Qin, I'm a dignified aircraft carrier engineer. I came here to run a set for you like a small electrical machinery factory. How can you, as the chairman of the board, show that?" Zhou Linlei tried to pretend to have a lot of experience. Said to Qin Hai. However, his slightly blushing face exposed his truth, this old man is really not good at doing this kind of bargaining.

"Zhou Gong is very true." Qin Hai said with a smile, "In order to thank Zhou Gong for his help, our group has specially prepared some local specialties of Anhe. When Zhou Gong leaves, I will arrange for you Sent to the airport to help you with your consignment without any effort on weekly work. "

"Local specialty?" Zhou Linlei waved hands again and again, "I don't want this."

"Why, is Zhou Gong asking for cash? Heck, this is a bit inconvenient for us financially, or should I let the accountant think of a solution again?" Qin Hai frowned, in fact, there is nothing difficult about this, just Qin Hai knew that it was absolutely impossible for Zhou Linlei to accept cash compensation. Even if Qin Hai wanted to give it, Zhou Linlei would not want it, so he said it intentionally.

Sure enough, Zhou Linlei heard the word cash and became even more embarrassed. His face turned purple. "Xiao Qin, don't do this. I was instructed by Ji Lao to help you. This is also mine. If you take your money for your own job, it will be a discipline violation. This is absolutely not allowed! "

"You don't want souvenirs. You don't want cash. What did Zhou Gong just say? What do I not understand?" Qin Hai said.

Zhou Linlei said neatly, "Isn't this a very clear thing ... You have promised me a lot of things at Ji Lao. Now that your problem has been solved, should you also consider how to help our troops solve the problem?"

"Haha. It turned out to be this, Zhou Gong, you said that earlier, didn't it?" Qin Haiha said with a smile.

"You little Qin, I know you can understand, you just deliberately teased me, old man, right?" Zhou Linlei pretended to be annoyed. He is more than 50 years old and can claim to be an old man in front of Qin Hai. Already. From time to time, he was dressed up tenderly. Everyone is proud of being old.

Qin Hai knew that Zhou Linlei was an honest man, and he devoted his whole heart to his carrier career, so he would not pretend to be stupid anymore. He nodded and said, "Zhou Gong, rest assured. As soon as I returned to Anhe a few days ago, I started to arrange this. I have learned that the research on graphite lubricants has now made a great breakthrough. It is expected that the finished products of industrial production can be seen within one year. The research work on supercapacitors has now arranged a team. Superconducting research is being conducted by the Superconducting Research Center of Beijing University. When in Beijing, Chen and I Professor Zong Ze said, he is very confident. As for the rare earth permanent magnet materials ... "

"I have already communicated with Mr. Sun Yuzhi. The cerium-based permanent magnet material he is currently working on is indeed very promising, and I am very confident about it." Zhou Linlei replied on behalf of Qin Hai.

Qin Haidao: "Yes, I also talked to Professor Sun. He said that he already understands your needs and will soon shift his energy to this aspect."

"This is great!" Zhou Linlei blossomed on his face. "So many problems, I can't do anything about it. I can't think of you being able to solve it in Xiao Qin. No wonder Ji Lao values ​​you so much."

"Oh, Zhou Gong. You haven't finished it yet, igbt's question. Don't you care?" Qin Hai asked.

"Igbt ..." Zhou Linlei shook his head. "This is a bit difficult, it's all on your little Qin, I'm a bit unbearable. You don't know, after talking with you at Ji Lao that time, I I sent a report to the research institute and proposed to purchase some igbt components abroad, and the research institute has reported this report to the Commission of Science and Technology. We will definitely master the technology of igbt, but in the short term, it will be purchased through procurement. It is still feasible to make up for technical shortcomings. "

The so-called igbt is the abbreviation of "Insulated Gate Bipolar Power Tube". In the simplest terms, it is a high-power electronic switch. By controlling the voltage on the gate, it can switch between on and off. . Compared with mechanical switches, the response speed of electronic switches can reach hundreds of thousands of times per second, and there is no fear of damage due to repeated switching. The triode in the radio is also an electronic switch. IGBT can be regarded as a special triode, which is characterized by higher voltage resistance, higher current, faster speed and better reliability.

The concept of igbt was first proposed in the late 1970s, and was successfully developed by the US Ge Corporation and the company in the early 1980s. Since 1986, igbt has been officially produced and gradually formed a series. In the following years, igbt's technology was continuously updated. The first generation appeared in 1988, which is called the plane penetration type; the second generation appeared in 1990, which was an improved plane penetration type; in 1992, the third generation, That is, the trench type; the fourth generation appeared in 1997, called the non-penetrating type; the electric field cut-off type appeared in 2001; the trench electric field cut-off type appeared in 2003 ...

There is a reason for semiconductor manufacturers' continuous innovation in igbt technology, which is that igbt is widely used. From the railroad, aerospace, power, oil and other pillars of the national economy, to the consumer electronics products such as inverter home appliances, digital cameras, and induction cookers, all can find igbt. Such a huge market can naturally attract countless heroes competing in the world.

However, mastering igbt's manufacturing technology is not easy. igbt is a device with a very complex working principle, which integrates the basic structure of almost all semiconductor devices. To manufacture IGBT devices that meet the requirements involves a series of microelectronic manufacturing processes such as photolithography, oxidation, ion implantation, thermal diffusion, and deposition of polysilicon. In order to reduce the on-resistance, engineers continue to reduce the size of the cell and increase the number of cells in parallel. To this end, the manufacturing process of igbt has been reduced from 5 microns to 0.5 microns, and the wafer size has been increased from 4 inches to 6 inches. 8 inches.

All these production processes were very difficult for China at that time, and there was almost no possibility of a breakthrough in the short term. Because of this, Zhou Linlei does not place too much hope on Qin Hai. In his opinion, Qin Hai can solve obstacles such as supercapacitors, superconducting coils, and permanent magnets. It is very valuable. Difficulties were imposed on Qin Hai, and some of them were too difficult.

After hearing what Zhou Linlei said, Qin Hai asked with a smile: "Zhou Gong, the igbt device used on the aircraft carrier catapult is not an ordinary commodity, can it be sold to us abroad?"

"It's man-made." Zhou Linlei didn't really have much confidence, so he could only answer, "I can't buy high-power igbt. There are some relatively low-power devices. By combining them in series, they can barely meet the requirements. Now. "

"But this way, we are still subject to others, Zhou Gong really does not want to master the core technology of igbt by himself?" Qin Hai continued to ask.

Zhou Linlei said: "How could you not want to? But how difficult is the semiconductor processing technology, Xiao Qin, do you understand? The difference between our country ’s semiconductor technology and foreign countries is not a mere star, and this technology is not just a rush. Can rush up. "

"Zhou Gong is right." Qin Haidao, "However, we can give it a try. It ’s a pity that we are completely sending it to foreign markets like igbt. We will have to develop our own power transmission technology and high-speed rail. Technology, if the igbt thing is completely in the hands of others, if people just click our necks, we will be uncomfortable. "

"What are you going to do?" Zhou Linlei became serious. He heard that Qin Hai was not just talking casually, but had some ideas of his own.

Qin Haidao: "I intend to take a two-pronged approach. On the one hand, we will mobilize domestic semiconductor research institutes and manufacturers to jointly solve problems. On the other hand, we will introduce technology to shorten the gap between us and foreign countries. In three to five years, we will initially form our own igbt. Industry, first meet their own needs, and then consider catching up with the world's advanced level. "

"I'm afraid that the way of introducing technology will not work." Zhou Linlei asserted, "In fact, the Science and Technology Commission has long had this idea ~ www.novelmtl.com ~ I also talked to several foreign companies that are leading in igbt technology. I hope to be able to introduce some technology. However, people are simply unwilling to cooperate with us, and the issue of technology transfer will be avoided. "

"I know this." Qin Haidao, "foreign manufacturers are aware that we do not master igbt technology and hope to use this to sell us high prices, of course, we will not be willing to transfer technology. However, if we directly The enterprise bought it? So why don't we transfer the technology without transferring it? "

"Buy it?" Zhou Linlei shouted, "Xiao Qin, are you too whimsical? A few of the world's top igbt manufacturers are giants in the semiconductor field. Don't say they won't sell, even if they want to sell, to Can't afford the financial resources of our country? "

"Ha ha, Zhou Gong, you are really right. However, we can't afford these top manufacturers, can we try it for second-tier manufacturers?" Qin Hai asked with a smile.

"Why, Xiao Qin, do you have a goal?" Zhou Linlei heard Qin Hai's words and couldn't help asking.

Qin Hai nodded solemnly and said, "Yes, I've already spotted an old British semiconductor company, Nice." (To be continued)
