Indeed, as Shen Danqing said, Changsheng Seiko's precision machining technology is like a plug-in in China at this time, and what others can't do with all their hard work, Changsheng Seiko can easily do it. If they master the principles of growing to make monocrystalline silicon, they can easily build more advanced growth furnaces.

Monocrystalline silicon and polycrystalline silicon are actually the same substance, the same crystal. It's just that one is the same direction of crystal arrangement and the other is disordered, so the material properties are far from the same, and the price is also far from the same.

How can we make the arrangement of silicon crystals consistent? After continuous experiments, scientists have come up with three methods: 1. The straight-pull method is also the most commonly used method. 2. The zone solution method is the best material for manufacturing high-voltage power distribution equipment. 3. The epitaxial method is the best method for manufacturing thin-film monocrystalline silicon, and the cost is high.

What Shen Danqing has to do now is the straight-pull method, which is relatively cheap and easy to manufacture on a large scale.

Guo Dong really didn't cover it, he only spent two days and Changsheng Seiko's technicians to learn the growth principle of monocrystalline silicon from experts from the Non-metallic Research Institute, and took people to carefully study the functions of the key parts of the monocrystalline silicon growth furnace, combined with several requirements put forward by Shen Danqing, he had a bottom in his heart. So he asked Zhang Xiangdong: "Director Zhang, is there a bigger graphite crucible?"

Zhang Xiangdong didn't know why, but he also knew that Guo Dong would not ask questions for no reason. He replied, "I sent someone to call the manufacturer and ask, can you tell me what the reason is?"

"It's nothing, I found that the graphite crucible was too small to make a 3-inch wafer. Please help me ask the manufacturer what is the maximum size of the crucible, because I want to build a growth furnace according to the crucible. Guo Dong briefly explained the reason.

He said it lightly, but it fell on Zhang Xiangdong's ears with a different meaning. It seems that as long as the crucible is big enough, he can build as much as a growth furnace. Zhang Xiangdong was afraid that he didn't know the difficulty, so he kindly said to him: "The size of the crucible is also determined by the size of the monocrystalline silicon rod that is lifted, and if it is too big, it will be wasted." ”

After two days of understanding, I estimate that we can build a growth furnace that can lift about 20 inches of monocrystalline silicon rods. Guo Dong saw that Director Zhang didn't believe him, so he asked him for help.

"What do you say? 20 inches, you know? The highest foreign can do 12 inches. Most manufacturers are still using 8-inch technology. You're not kidding me!" Zhang Xiangdong was so surprised by Guo Dong's words that his mouth opened wide enough to swallow a fist. Disbelief, he asked rhetorically.

"Director Zhang, don't worry, I'm sure, you can ask according to what I said! I guess I may have to customize it for them, they will definitely not have such a large ready-made one. Guo Dong assured him that Director Zhang would have nothing to say, and he would not be able to find any responsibility. He didn't say anything anymore, and went directly to call and ask in person.

As soon as the phone was connected, he first said, "Hey, hello!" and the other end of the phone politely replied "Hello".

"I'm a customer who bought crucibles from you, and I want to ask if you can customize crucibles!" Zhang Xiangdong explained his intention to the other party.

"Yes, we have this business. How much level do you need to customize?"

"We wanted a custom crucible that could lift a 20-inch class. Zhang Xiangdong also pretended to be forced back, and deliberately said lightly.

"What? You want to make it so big! Then I have to ask the master in the factory. You tell me your phone number, and I'll call you again in the afternoon, okay?" Although the other party didn't believe it, he wouldn't ask if he had money to make, and that was none of his business.

"Okay, my phone: ....... I wait for your good news. Zhang Xiangdong told him the number and hung up the phone, and this time he didn't have the bottom. Going from 3 inches to 20 inches is not a simple addition problem, and he estimates that the manufacturer is not sure.

In the afternoon, the other party's call came on time, and Zhang Xiangdong was already waiting by the phone, this matter was too important for him not to pay attention to. He picked up the microphone, and the voice of the person in the morning came from inside: "Hey, I called you in the morning, I asked the masters in our factory, and they all said that it was too difficult, and we were not sure, we still have to experiment." If you have to customize, the price will be higher, can you accept it?"

"The price is not a problem, you can do it with confidence, how much deposit is needed, tell me the account number and I will have someone call you immediately. All I want is to get the crucible as soon as possible. Zhang Xiangdong, as Shen Danqing's subordinate, also learned his temperament as a big dog. Don't blame him, Changsheng Investment Group is too rich. Think about it, how a "rich" person is to use Chinese employees to earn money from developed countries, and only spend money in China.

Rich is naturally everything easy to say, the other party saw that Zhang Xiangdong looked not bad for money, and his heart was even happier, with honey in his mouth when he spoke, and how bad could the salesperson's mouth be. Zhang Xiangdong and he negotiated with each other on the phone and hung up the phone. "I hope the other party can do it!" Zhang Xiangdong prayed silently in his heart.

Zhang Xiangdong called Shen Danqing as soon as possible to tell Shen Danqing the ins and outs of the whole matter, and only the boss can make up his mind about this matter.

Shen Danqing listened to Zhang Xiangdong finish what happened, and was silent for only a few seconds before replying in a categorical tone: "We can't wait, we don't have time to waste, there are still too many difficulties waiting for us to overcome." You ask Guo Dong to start manufacturing the equipment according to the size that can lift a 20-inch monocrystalline silicon rod, and the equipment is just the beginning, and there are many experiments to collect data. In addition, for that special chemical solution, you ask the Institute of Chemistry to think of a way, maybe you can ask the technical information department to go abroad and find a way to buy some samples back. Forget it, I'll say hello to the technical information department, goodbye. ”

When Shen Danqing hung up the phone, Zhang Xiangdong still held the microphone and didn't put it down for a long time. After listening to the boss's words, his heart was already surging. What kind of vision and open-mindedness is this? The experts in his institute have studied it for nearly two years, but there has been no progress. The boss only looked at it once, pointed out several key problems, and even sent Guo Dong to lead the technicians of Changsheng Seiko to design the growth furnace. Listening to Guo Dong's tone, it seems easy to build a 20-inch monocrystalline silicon rod-level growth furnace, which proves that the boss's vision is very accurate, as if he had expected it a long time ago. You must know that China can only make 3-inch monocrystalline silicon rods at this time, which is still equipment technology imported from abroad, and only reaches the purity of 6 9s. Thinking of this, he admired his boss even more, and even though he was more than twice as old as his boss, it didn't diminish his fan mentality in the slightest. The boss is already a legend that cannot be measured by age.

After Guo Dong got the instructions of the boss, he led the technicians of Changsheng Seiko to return to Changsheng Seiko. He first held a discussion meeting with the participating designers, at which he shared his thoughts and requirements: "I will add a few more to the boss's requirements. The maximum temperature should be above 1650 degrees, the mechanical control equipment should be made with our best technology, the furnace body should be insulated, and the furnace cover must be able to be automatically switched and closed, and it is a waste of time to twist the screws every time. Then he assigned the design tasks to who was responsible for the overall design, who was responsible for the design of a key component, who was responsible for the design of the furnace body, and who was responsible for the design of the furnace cover.

After the meeting, he asked people to contact the Institute of Metals and asked them for high-temperature alloys and high-purity tungsten alloys. Tungsten alloy is used to make resistance wires. Other materials for making growth furnaces are available in their company, and the Institute of Non-Metallic Materials for Thermal Insulation Asbestos Materials has them. In this way, Changsheng Seiko acted intensively.

After Shen Danqing arranged the R&D tasks of Changsheng Seiko and Non-metallic Materials Research Institute, he went to the Electronics Research Institute. In his previous life, he saw someone on the Internet mentioning parallel engineering, the name is very high, but the meaning is actually very simple.

Today, he is also going to engage in parallel engineering, and the company will be manufacturing microchips in two years at most. Therefore, the Institute of Electronics is also going to start designing chips, there are many types of chips, and with the current strength of the Institute of Electronics, we can only design simple chips, such as industrial control chips, embedded chips, low-end memory chips, etc.

Because of the prior notice, when Shen Danqing arrived at the Institute of Electronics with his secretary Liu Zeping, Hong Tao warmly received the two of them with several middle-level managers.

Hong Tao also enthusiastically helped Shen Danqing open the car door, as a Hong Kong native, he has been exposed to the rank since he was a child. Therefore, the action is very natural, not at all contrived, on the contrary, there is a gentlemanly demeanor.

"Owner, welcome. While helping him open the door, a polite greeting played the finishing touch.

Shen Danqing, who was a dick in his previous life, when had he ever seen this kind of formal gentlemanly etiquette. No matter how much I have seen it on TV, now that I am courteous in person, I naturally feel different.

"Well, Director Hong, you're good! I'm here to burden you today, but it's not a hospitable!" "In a good mood, Shen Danqing spoke with a bit of humor.

"Where, where, the boss puts a burden on us is to look up to us. After Hong Tao said a few polite words, he took a step forward to lead the way, and continued in his mouth: "Boss, please, let's go to the conference room and talk!"

Everyone sat at the oval conference table in the small conference room according to their duties, Shen Danqing sat with his head blocked, Liu Zeping sat on his right hand, and others sat on both sides.

"Director Hong, are you a doctor in the United States, have you taken over the chip design?" Shen Danqing did not assign a task, but asked Hong Taodao.

"I studied electronic engineering, and integrated circuits are compulsory courses, and I have studied this area during my master's and doctoral studies. In a few simple words, Hong Tao explained his expertise and experience.

"Smack" Shen Danqing listened to him, and couldn't help but pat the case and said: "That's better, since you have experience in this area, I'm relieved." I'm here today to ask you to start designing chips, starting with simple industrial control chips. Director Hong, is there a problem?"

"No problem, boss, I used to design the industrial control chip. After Hong Tao heard the boss's request, he immediately patted his chest and promised.

"But I have a request, we can't copy someone else's instruction set, we have to change it. For example, when a program invokes the instruction set, it must use Chinese characters as the general annotation, such as: save, take, line, point, etc.
