No one knew that Jiang Xinwei's unintentional words were purely pretending.

He was not an expert in monocrystalline silicon, and he did not understand many of the specialized numbers on the report. It can even be said that he doesn't know whether those professional numbers jù represent good or bad, and the only number jù he can understand and be sure of is the purity of monocrystalline silicon.

As a pseudo-expert in the field of monocrystalline silicon manufacturing, Jiang Xinwei also clearly knows that the purity of monocrystalline silicon is only high-quality monocrystalline silicon when it reaches 99.9%, and below this value is not considered high-quality.

Moreover, the value of monocrystalline silicon has a lot to do with 99.9%, and this number is like a commonly used threshold value in computer control, and the value of more or less than this number can be described as very different. If the purity is higher than 99.9%, the value of monocrystalline silicon can be more expensive than diamonds, and it can be used to make large-scale integrated circuits or ultra-large-scale integrated circuits, and below this number, its value is greatly discounted, and it can only be made into some ordinary chips, and can only be sold at the price of cabbage.

"The purity is too low?...... How much?" asked the expert, surnamed Chen, as he looked at the report sheet.

Jiang Xinwei hadn't answered yet, but Professor Zhou, who was holding the report paper, said dissatisfiedly: "Who said that the purity is low? It's 99.84 percent! This is the order of magnitude that can only be achieved in China's real room, which is very, very good, what else do you want? We can use it to produce the silicon wafers we need and use them to make chips!"

As we all know, material production is generally divided into real room production and industrial production, which are very different.

The production of the real yàn room can be said to be completely cost-free, and samples are produced at a high cost, and the quantities produced are generally very small. They are manufactured to meet the needs of numerous businesses and numerous customers. The main purpose is to verify the correctness of the research results of scientists, mainly to achieve or solve the problem of "can and cannot", and of course, sometimes to find scientific ways and methods for industrial production.

However, industrial production is mass production, which is to satisfy many enterprises and customers. The purpose of their production is to provide large quantities of goods for the desired profit, and to achieve or solve the problem of "whether there is a profit".

Therefore, it is impossible for industrial production to ignore the cost, it is impossible to be too refined for the product, and only to achieve a balance between cost and quality, and profit is the first. Generally speaking, the quality of the new materials produced in the real room is much higher than that of the new materials produced by the enterprise.

Professor Chen looked at the number jù on the test report. He also said to Jiang Xinwei dissatisfied: "You are not satisfied with such a high purity, you are still going to the sky in one step to surpass Western countries in a short period of time? This is a large-scale industrial production, this is not in the real room, it is good to be able to achieve this purity!"

Jiang Xinwei just smiled and didn't argue. Because he understands what they think.

Their idea is not only that the technology has to be improved step by step, but now we should be content to solve our production and scientific research needs, don't be ambitious, their idea is that since we can produce such a high purity in the factory, it is not difficult to improve the purity in the real room, there is no need to be harsh on Professor Jin here, if they are as demanding as him, it will chill the hearts of scientific research workers. It's so unkind.

Although Jiang Xinwei also belongs to Professor Jin and them, he is also one of the owners of this scientific research achievement, and he is the main owner. But it still angered the experts.

Of course, experts have other considerations: at this stage, China's demand for silicon wafers for manufacturing VLSI is not very large, because China does not have the mature technical ability to manufacture LSI circuits, let alone manufacture VLSI circuits, and only a few famous universities and some departments of the Chinese Academy of Sciences are trying to do this.

These experiments require very few high-quality silicon wafers and monocrystalline silicon, and some can be purchased from foreign countries through various overseas channels. Some can be prepared through their own domestic real yàn room. Why do you Jiang Xinwei have to let industrially produced products achieve such precision? Is this necessary? It's just grandstanding.

Soon, the monocrystalline silicon rods of the other two monocrystalline furnaces were also taken out. The report of the relevant test numbers was also quickly sent to the experts. The quality of the three monocrystalline silicon rods is about the same, and the purity of Jiang Xinwei's concern also fluctuates around 99.8%.

Except for Jiang Xinwei. Other people are very satisfied with this purity, especially the purity produced by the three monocrystalline furnaces is so high, which means that China has made a substantial breakthrough in the purity of monocrystalline silicon, and the quality of monocrystalline silicon in developed countries is not far behind, but there is some distance from foreign high-quality monocrystalline silicon.

Therefore, the appraisal meeting went very smoothly, and the new single crystal furnace developed by Dai Lao and their semiconductor materials research institute won unanimous praise from the experts attending the meeting.

Because everyone is so happy with the results achieved, so much favor for the newly produced single crystal furnace (yes, in just a few months, it has made progress that has not been achieved in previous years, can you not be happy?), Jiang Xinwei did not show off, and at this time he did not propose his magnetron straight-pull technology.

He said in his heart: The current product quality can also meet my country's demand for monocrystalline silicon, so let them produce it like this first, and it is not too late to talk about these technologies when I have free time.

As for the crucible coating technology and zone melting technology he proposed before, he believes that Dai Lao and his researchers are working day and night on it, and he also believes that it will not take long for them to solve it. As long as the excellent lamination is researched, as long as the zone melting technology is mastered, the quality and purity of monocrystalline silicon will be further improved.

"Hehe, it won't be long before there will be an unexpected strong competitor in the world semiconductor market from Western countries. Jiang Xinwei thought happily in his heart.

After the meeting, the celebration banquet, and accepting everyone's congratulations, Jiang Xinwei said goodbye to Dai Lao and others and went to Leng Lan's Feixun wireless equipment company. Anyway, Su Dingyu is in charge here, and for Feixun Materials Company, it is to constantly buy the monocrystalline furnace produced by the factory under the guidance of Dai Lao's research institute, buy as much as you want, and put it into production when you buy it, and now there is very little monocrystalline silicon with a purity of more than 99% in China, and it is very scarce, and they don't have to worry about selling it.

In fact, Dai Lao and they couldn't produce many single crystal furnaces for a while, these three new single crystal furnaces are said to be brand new, in fact, they have carried out a large range of transformation on the original single crystal furnaces, and many mechanical parts are still the original single crystal furnaces. Moreover, the crucibles used in the single crystal furnace of this appraisal meeting were still borrowed from Italy, and were misappropriated from the spare crucibles that came with the Italian single crystal furnace. The two control plates in the control system are also borrowed from Italian spare parts, not manufactured by our own country.

If we wait for the crucibles and control plates made by our country to come out, it will take at least several months before the technical appraisal meeting can be held. This is undoubtedly a delay and unnecessary. After all, the appraisal meeting is only to verify the production principle of the single crystal furnace, just to show that Dai Lao has mastered the main production technology of the single crystal furnace, as long as the problems in the production details can be solved in the future, and there is no need to rigidly insist that domestic crucibles must be used.

Jiang Xinwei naturally agreed with Dai Lao's opinion: "In case we can't produce qualified crucibles in China in the future, we can't stop producing single crystal furnaces, and we can completely take the method of ordering from abroad to solve the problem, or replace them with spare crucibles attached to Italian single crystal furnaces for a period of time." ”

Jiang Xinwei said goodbye to Dai Lao and Su Dingyu and went to the paging equipment company to help Leng Lan deal with some production and business problems, and to make decisions about things that only he can do.

Seeing Jiang Xinwei appear, Leng Lan raised her tired eyes, and said in a hoarse voice: "You are finally here?

Jiang Xinxu smiled and said, "I only have one pair of hands and one head." Why don't we stop for a moment and everyone take a break? Anyway, this money can't be made, so why do we have to be in such a hurry?"

"Okay, okay, let's stop doing it from today, and immediately notify Guo Qian to come back and go to the scenic spot first...... No, go home and sleep first, rest for a week. Leng Lan said exaggeratedly, but then snorted and said, "It's really hypocritical after becoming the boss, if I were a person with a small belly, I would really leave my work and go to sleep." ”

Jiang Xinwei said seriously: "What I said is true, if you continue to do this, you will definitely tire bad people." ”

Leng Lan still didn't believe it, and said: "Hmph, don't coax us little women, tell me, which person who is the boss doesn't want his company to make money, and now he can earn hundreds of thousands without opening a launch pad, which is faster than robbing a bank, will you be willing to let us go to sleep and still receive your salary?"

Jiang Xinwei said with a smile: "My boss is different, now I really hope that you will rest first, and the project can be done slowly." …… If you are tired now, who will make money for me in the future, no matter how stupid I am, I know the truth of the long stream, right?

…… , Leng Lan, seriously, the golden age of wireless paging is far from coming, don't look at the many units that require the construction and opening of wireless paging transmitters, but there are not many people who use pagers, basically they are used for official contact, and the basic urban unit employees who wear pagers. Only when most of the people started wearing pagers, that was when we were in full swing. ”
