Chapter 320 is hugely rewarding

Guo Zhuocheng's words were half-true, and it was true to participate in the report meeting of heroes and models, but he did not say that he was a hero who sat on the rostrum to make a report.

Grandma naturally thought that her grandson came to listen to the report, so she breathed a sigh of relief and said, "That's the case." That's good, it means that my grandson is good at school and was elected as a student representative by the school teacher, right? You came to Beijing with those battle heroes, right? Many of the heroes are fighting against the enemy on the borders of your southern Yunnan province. ”

Guo Zhuocheng smiled and nodded.

Tian Hongmeng also thought that this was the case, and said, "Then let's eat quickly." Go back early after eating, so as not to lead the teacher. Although you are already a college student, you also have to talk about organizational discipline. ”

Facing the two elders with strict self-discipline, Guo Zhuocheng said helplessly: "Grandpa, this is home, I finally came to you, how can you treat me like this?" As soon as I arrived, I was asked to go back. Don't worry, I've already asked them for a leave of absence, and I can go back for up to 24 hours, that is, by this time tomorrow. ”

Grandma smiled happily: "It's good for young people to be disciplined [Makoto, you take a rest first, grandma will make you the best tenderloin.] Yuan Mei, the two of us are going to cook. ”

Yuan Mei said enthusiastically: "Mom, you can talk more with Humble Cheng, your ancestors and grandchildren haven't seen each other for a long time, I often hear you talk about him and praise him, now you can talk more, I'll cook." Make sure to cook a good table and make him happy. ”

Hao Xiaoxiu said with satisfaction: "Don't do too much, you can't eat and waste [Cheng This kid can eat anything, he has a good appetite.] ”

When Tian Weiqing and Yuan Mei were busy in the kitchen, Guo Shucheng asked his grandmother Hao Xiaoxiu: "Grandma, how is the exchange in the United States?" ”

My grandmother said happily, "Okay, okay, I learned a lot of things there that I never thought of before, and I gained a lot." It's a pity that the time is too tight, eight months seems to be a lot, but if you learn software, you can't learn hardware, and you can't learn software if you learn hardware. After this study, we will be able to avoid many detours in our future research and save a lot of time and money.

Honestly, thanks to you this time. In particular, the forward-looking knowledge you talked to me about was very useful in this study, and the Americans could not figure out the current state of our technology, and they suspected that we had gone ahead of them in the field of semiconductor theoretical research, and they thought that there had been a mistake in China's technical intelligence work, and several well-known experts even came to discuss theory with us and answered some of our technical questions very happily. If it weren't for the fact that before I went abroad, you said that this was to fight wits with the Americans, I would still consider myself a liar. I'm lying to them with something illusory. ”

With his grandmother's happy look, Guo Shucheng said, "How can it be a lie?" They are not children, they are experts, so they naturally know whether what you say is true or false, and what we say cannot be true, and there are obvious benefits to their technological development. ......, grandma, how much equipment did you buy this time? ”

Hao Xiaoxiu's smile disappeared a lot, and she said, "It's hard to buy." ......, there are no big equipment, especially cutting-edge equipment, and we don't buy much semiconductor manufacturing equipment that we need. Although they think that our theoretical level is on par with theirs, they think that we can only reach the preparation level that is compatible with the theoretical level in the real room, and that the products can only be prepared in the real room and cannot be industrialized, saying that our production level is not comparable with theirs at all, so these cunning Americans are not willing to sell us large equipment, and only promise to sell us some instruments and meters. ”

Grandfather Tian Hongmeng said angrily: "These Americans shout the main reason every day, but they discriminate against us, deliberately stick our necks, sell everything to the price of the dead high, and are unwilling to sell us high-end equipment." ”

Guo Zhuocheng said calmly: "I think it is understandable, there is no free lunch in the world, people are capitalists, even if there is no ideological gap, they are still to make money." They just want to monopolize the market with advanced technology, they can't make enough money, and they may lose their own market, so why sell us advanced equipment? ”

Grandma said: "You kid, everyone is in the eyes of money, and you still help them speak." ......, however, what you said is also true, and if you think about it, it is also true. ......, no matter what the technology is, it is better to master it yourself, and be self-reliant. ”

Guo Shucheng asked: "What kind of instruments did you buy this time?" ”

Although the equipment purchased is from the United States, it is still confidential and cannot be said casually, but Hao Xiaoxiu still simply replied to his grandson and said: "It is mainly used for inspection, testing, and monitoring instruments." ”

Although this kind of instrumentation can not be directly used in the production of semiconductor raw materials and semiconductor devices, it can detect whether the materials and products are qualified, and can control the yield of products.

To give a simple example: without sophisticated material testing equipment, workers will not know how good the semiconductor material they are making, how many impurities are in the material, let alone what improvements can be taken to reduce them. With this kind of equipment, it is possible to compare the products manufactured by various methods, strengthen or improve the manufacturing methods that can produce high-purity products, and eliminate or improve the manufacturing methods that produce low-purity products, so that the manufacturing level of the factory can be improved.

Being able to buy these instruments and meters is the reason why Hao Xiaoxiu and the superior leaders are happy, and they didn't buy other high-end equipment, which just made them a little frustrated.

Hao Xiaoxiu sighed and said: "It's not that I can't afford our ......, the speed and scale of Americans' production of semiconductors are simply incomparable to us." How much monocrystalline silicon does one of our national key factories produce on average per day? Only a dozen kilograms. But an ordinary factory can produce several tons of monocrystalline silicon every day, and its quality is much better than ours. We really have a long way to go. The more I studied, the more I felt that I had a heavy responsibility and the more I felt the urgency of time. Even in my sleep, I really want to find a good way to increase the production of monocrystalline silicon and solve the bottleneck of our lack of high-quality monocrystalline silicon and the development of semiconductors. ”

After listening to his grandmother's words, Guo Zhuocheng's heart moved, he remembered the things about the manufacture of monocrystalline silicon in his previous life, and remembered that there was a public information that said that there was an extremely simple way to improve the quality and quality of monocrystalline silicon products.

This method was invented by the Americans, but they have been carrying out a technological blockade on other countries, and even Japan spent a lot of money to introduce it. When Japan knew that the technology was so simple and that the cost of introducing it was so high, the person in charge of introducing it almost vomited blood and died.

I am very annoyed that the smart Japanese did not think of it, why let the Americans figure it out in advance. No wonder the Americans did not apply for a patent for this, it turns out that the Americans are also cunning and cunning, knowing that if they apply for a patent, once the technology is disclosed, other countries will not need to go through the United States to provide technical support and do not need to pay patent fees to secretly improve themselves, thus greatly increasing the output of monocrystalline silicon and impacting the monopoly of the United States.

Because Japan spent a lot of money to introduce this technology from the United States, after the establishment of diplomatic relations between Japan and China, there have been a lot of technical exchanges between the two countries, but when it comes to the technical exchange of monocrystalline silicon, the Japanese not only did not introduce the simple technology to China, but misled the Chinese technicians, and repeatedly discussed the temperature control and time control of the monocrystalline furnace. Chinese technicians have spent countless manpower and material resources without really increasing the output of monocrystalline silicon, and finally imported a large number of high-priced monocrystalline silicon products from Japan and the United States, which has made the not rich Chinese manufacturers lose blood again and again.

However, Guo Zhuocheng is not an expert in the field of semiconductors, and the technology of single crystal furnaces is all from books or the Internet, and now he can't determine whether what he remembers in his mind is true, so he decided not to tell his grandmother for the time being, and wait until he has the conditions to conduct the test.

In his arrival, his current conditions are no worse than his grandmother's, and the manpower and material resources he can mobilize are even far greater than his grandmother's, rather than letting his grandmother work hard to verify, once successful, he will definitely let his grandmother treat him with a more strange eye, it is better to "prove" this method through guò action that he has figured out in practice.

Still, he asked, "Grandma, why are Americans able to mass-produce high-quality monocrystalline silicon?" ”

Grandma said a little enviously: "First of all, people have money and can spend a lot of money to build a clean and dust-free workshop. The annual funding of our laboratory is not enough to build one-tenth of the workshop. With this kind of dust-free air adjustable and temperature controllable workshop, the quality of their products is naturally a grade higher than the quality of our products.

There is also a high level of technology, only their monocrystalline furnace is not fundamentally different from ours than ours, but their monocrystalline production cycle is less than three days, and ours must be seven days. Our crucibles don't have to be replaced more than three times, while theirs can last for a year or more. This crucible replacement alone can save a lot of money, I really don't know how they achieved it. I paid attention to it for a long time and asked several times, but they just wouldn't tell me. ”

This is someone's job, can they sue you?
