CC, the fastest update material empire!

Zhou Lin Lei ran to An River to give Hongze Motor Factory as a temporary worker, and he helped Qinhai to sing the drama, Liu Qiping, all because Qin Hai promised to solve the relevant technical issues related to the aircraft carrier.

Now that he should do it, it has been done, and it is time to ask Qin Hai to give a return.

"Qin, I have a good aircraft carrier engineer, and I will give you such a small motor plant running dragon case. You are chairman, how can you say it?"

Zhou Lin Lei tried to install a very high-rise experience, and said to Qinhai.

However, his slightly, a slight face has exposed his truth. This old man is really not good at engage in this kind of trick.

"Zhou Mong said is very.

Qin Hai laughed, "In order to thank us to help us to help us, our group specially prepared some natural native products of Anhe, when we walk, I will arrange people to send you to the airport, help you Consignment, there is absolutely no effort to wear.

"Tolerant products?"

Zhou Lin Lei hooks in love again, "I don't want this.

"Why, is Zhougong wants to cash? Oh, this is a bit less convenient to operate this financial, or I want to think about it again?"

Qin Hai felt frowned, in fact, there is something difficult, but Qin Hai knows Zhou Lin Lei is absolutely impossible to accept cash rewards, even if Qin Hai wants to give, Zhou Lin Lei will not want, so he will intentionally.

Sure enough, Zhou Lin Lei heard the two words in cash,% more embarrassed, the face became purple: "Xiao Qin, you can do this, I am from the old instructions to help you, this is me The job work, if you take your money, it is a discipline, this is absolutely not allowed!

"You don't have to native products.

Don't be in cash, then the week has just said that what does it mean? Why don't I understand it?

Qin Hai said.

Zhou Lin Lei said: "This is not very clear. You can promise me a lot of things in the old, now your problem is solved, is it to consider how to help us solve the problem.

"Haha, it turned out to be this."

When you have said, you can't get it. "

Qin Hai haha ​​laughed and said.

"You Qin, I know that you will definitely understand, you are deliberate to tease my old man, right?"

Zhou Lin Lei is worried, he is 50 years old, and he can claim to be an old man in front of Qin Hai.

I dared from time to time, everyone is old.

Qin Hai knows Zhou Lin Lei is an old man, and a heart is in his aircraft carrier.

So even if it is still stupid.

He nodded and said: "Zhou Mong, you can rest assured, I have been to the Anhe a few days ago, I have already started to arrange this."

I have learned that the study of graphite lubrication materials has now been a big breakthrough, which is expected to meet the finished product of industrial production within one year.

The research work of super capacitors is now arranged.

Superconductive research is to engage in the Jingcheng University Superconducting Research Center.

When I was in Beijing, I talked with Professor Chen Zongzu.

He is very confident.

As for rare earth permanent magnet materials ... "

"I have already exchanged with Sun Yuszhi teacher. He now is now engaged in cerium-based permanent magnet material, which is really very potential, I am very confident about it.

Zhou Linyi replied to Qinhai.

Qin Haidao: "Yes, I also talked with Professor Sun, he said he has understood your needs.

And will move the energy to this aspect.

"This is too good!"

Zhou Lin Lei is happy to open, "So many problems, I am doing Mo, I can't think of you can solve it in Xiaqin, it is no wonder that I don't want to pay attention to you.

"Ha ha.

Zhou Mong, you haven't asked, IGBT's question, are you not concerned? "

Qin Hai asked.

IGBT ... "

Zhou Lin Lei shook his head, "this difficulty is a bit big, all press it on your small Qin, I am unbearable.

You don't know, after chatting with you, I have reported a report to the Research Institute, proposing some of the IGBT components abroad, and the research institute has reported this report to the Science and Technology Committee.

IGBT technology, we will eventually be mastered, but in the short term, by purchasing to make up for technical insufficient technology, it is still feasible.

The so-called IGBT is "insulated gate bipolar power tube"

The brief referred to, in the easiest way, it is a high power electronic switch that can be converted and turned off by controlling the voltage on the gate.

Compared to mechanical switches, electronic switches can be as high as hundreds of thousands per second, and there will be no concerns due to repeated switches.

The triode in the radio is also an electronic switch, and IGBT can be seen as a special triode, which is characterized by higher withstand voltage, greater current, faster speed, and better reliability.

The concept of IGBT was earliered in the 1970s. In the early 1980s, the US GE and RCA were successfully developed.

Since 1986, IGBT began to get formal production and gradually forming a series.

In the following years, IGBT technology continued to update. In 1988, the first generation is called a flat penetration; the second generation appeared in 1990, which is the improved planar penetration; in 1992 is the third generation, Typically, the fourth generation; in 1997, it is called non-penetrating type; an electric field cut-off type has emerged in 2001; a trench-type electric field cut-off ... Semiconductor manufacturers have continuously introduced new in IGBT technology. It is why, that is, IGBT has a wide range of applications.

Dachang to rail transit, aerospace, electricity, oil and other national economic pillar sectors, small to frequency conversion home appliances, digital cameras, and induction cookers and other consumer electronics, all can find IGBT.

Such a huge market, naturally can attract countless world heroes to compete.

However, to master the manufacturing technology of IGBT, it is not easy.

IGBT is a very complicated device that is almost integrated with almost the basic structure of all semiconductor devices.

To make the IGBT device that satisfies the required requirements, a series of microelectronic manufacturing processes such as photolithography, oxidation, ion implantation, thermal diffusion, deposition polysilicon, etc. are involved.

In order to reduce the on-resistance, the engineers continue to reduce the size of the single cell, increase the number of cells in parallel, for this reason, the manufacturing process rules of IGBT fall from 5 microns to 0.

5 microns, while the wafer size is increased from 4 inches to 6 inches and 8 inches.

All of these production processes are very difficult for China's Chinese, and there is almost no possibility of making breakthroughs in the short term.

It is also because of this, Zhou Lin Lei does not send too many hopes to Qin Hai. In his opinion, Qin Hai can solve the over-capacitor, super-guided coil, permanent magnet material, etc., it is already very difficult, and put the IGBT like this. Difficult to impose in the Qinhai, there is no one to be too strong.

When I heard Zhou Lin Lei, Qin Hai smiled and asked: "The IGBT device used by Zhou Mong, the aircraft carrier is not ordinary goods, can we sell foreign countries?"

"Things are people.

Zhou Lin Lei did not actually have too much grasp. I can only answer the way. "I really can't buy high power IGBT. There are some power relatively low, and it is barely able to meet the requirements by combining the series.

"But this way, we are still subject to people, Zhou Mong really doesn't want to master the core technology of IGBT?"

Qin Hai continued to ask.

Zhou Lin Lei said: "How can I not think? But how big is the difficulty in semiconductor processing technology, Xia Qin, do you understand? The semiconductor technology and foreign differences in our country are not a hierarchy, and this technology is not just rushed. It can be rushed up.

"Zhou Mong said right.

Qin Haidao, "But we can try it, IGBT is so big, we are completely giving to foreign countries, it is a pity.

In the future, we have to engage in our own transmission electrical technology, high-speed rail technology, if IGBT is completely mastered in others, people casually card, we are uncomfortable.

"How do you plan?"

Zhou Lin Lei seriously, he heard that Qin Hai was not casually talking, but there were some ideas.

Qin Haidao: "I intend to mobilize the semiconductor research institutions and manufacturers in the country, on the other hand, the introduction technology, shorten the gap between us and abroad.

With three to five years, we initially form our own IGBT industry, first satisfy your own needs, and then consider chasing the world's advanced level.

"Introducing this road, I am afraid you can't get.

Zhou Lin Lei sees a confirmation.

However, people are not willing to cooperate with us, involving the issue of technology transfer, and avoids it.

"I know this."

Qin Haindao, "Foreign manufacturers see the technology we don't master IGBT, I hope to sell this high price to us, of course, will not be willing to transfer technology.

However, if we buy a company with this type of technology directly? So transferring does not transfer technology, isn't we talked about? "

"Buy?"

Zhou Lin Lei's tongue, "Xiao Qin, you are too vicious, do you have a big top IGBT manufacturer, is a giant in the semiconductor field. Don't say that they will not sell, even if they want to sell, in our country's financial resources, I can't afford it? "

"Haha, Zhou Mong, you are really right."

However, these top vendors can't afford it, can we try second-line manufacturers? "

Qin Hai asked in a smile.

"How, Xia Qin, have you go to go?"

Zhou Lin Lei listened to the words in Qin Hai, I couldn't help but ask.

Qin Hai has solemnly nodded, saying: "Yes, I have stared on a, the UK's old semiconductor company, Nice.
