Zhang Shouqing couldn't hold back his unbearable mood and immediately called his assistants and students from the University of Technology, and a total of 8 researchers went to Lin Qiangsheng's monocrystalline silicon production workshop.

Due to the low purity of the current polysilicon seed material in China, all the polysilicon raw materials used in the production workshop are imported, and quartz crucibles, barium hydroxide, and inert gas are also imported.

After the research of Zhang Shouqing and others, the insulation cover on the single crystal furnace found that it can really control the temperature well, and its computer control system really achieves an accurate grasp of the temperature.

At the beginning, Lin Qiangsheng bought a batch of 2.5-inch monocrystalline furnaces, and later foreign countries soon successively launched 3-inch monocrystalline furnaces, and 2.5-inch furnaces faced elimination.

Lin Qiangsheng simply ordered a batch of 3-inch monocrystalline furnaces and shipped the 2.5-inch furnaces in his hands to Hong Kong.

He also ordered a heat screen device for a machinery company in the United States, and the company added temperature and other sensing control systems according to his wishes, and even they didn't know what the customer was making the lid for. But it doesn't matter, many design companies will adopt this approach, and even Apple's designers have not known what product they have in their hands for a long time.

Lin Qiangsheng also made a single crystal furnace lifting device in another company in another region of the United States, using multiple servo motors to provide power for rotation and lifting, and the control was also controlled by computer. Then I found a computer company to make an automated system and integrate the two sets of things.

It is not all right to manufacture this set of hot screen device and lifting device, and developed countries such as Europe and the United States have not yet mastered the technology of single crystal furnace hot screen, and those who have ideas are also secretly conducting experiments. In order to keep it confidential, Lin Qiangsheng could only take the product back and test the data himself.

Zhang Shouqing led people to start testing a single crystal furnace, and they had to test various temperature data. Fortunately, these have theoretical values. The motor speed data of the lifting device also requires them to explore a lot.

In order to make the lifting system truly automated, Lin Johnson asked Ernst & Young, which has not yet set off, to participate in this project to provide program support. The experimenter explored a set of improvement processes, summarized a set of data and entered them into the control program, and the program adaptation of 40 single crystal furnaces was inevitable.

Quartz crucibles, silicon, barium hydroxide, inert gas, these raw materials are imported from abroad. Quartz sand in Europe, America and Japan has always been better in purity and high quality than domestic quartz sand, and the purity of polysilicon raw materials is also higher, which has not caught up with foreign countries in China until the 21st century.

After Zhang Shouqing found out that everything in Lin Qiangsheng's place was imported, he once ridiculed him for not being domestic except for the floor and wall.

Lin Qiangsheng told the old man that the paint on the cement wall on the ground was also imported, and the old man almost collapsed.

"Which country's technology is this crucible coating made of barium hydroxide?" Zhang Shouqing wore a set of gas masks and asked Lin Qiangsheng loudly. Wearing insulated gloves, he was holding a quartz crucible that had just been heated to 300 degrees Celsius in an oven and sprayed with a barium hydroxide solution in less than 3 minutes.

Because barium hydroxide is toxic, Lin Qiangsheng also wears a gas mask, and he said loudly to Zhang Shouqing: "This is what I invented." You'll have to keep it a secret, old man! ”

"You?!" Zhang Shouqing looked at Lin Qiangsheng suspiciously through the mask, and in an instant he smiled and said, "Okay, I'll keep it a secret for you!" But first try this coating to see if it works! ”

Lin Qiangsheng smiled, and he didn't care if Zhang Shouqing would give him a real secret, anyway, he didn't care, because barium hydroxide is poisonous, and the most terrible thing is that long-term exposure to it can make people get a lot of diseases and cause hair loss. Lin Qiangsheng doesn't want to be a bald man, so he won't operate it himself in the future.

The new crucible coating performs very well. After physical and chemical reactions, a dense and tiny barium silicate crucible crystal layer is formed on the surface of the quartz crucible. It can protect the quartz crucible, prevent the monocrystalline silicon from reacting with the quartz crucible during the high-temperature drawing process, and improve the service life and growth yield of the quartz crucible. In addition, it increases the strength of the quartz crucible and reduces high-temperature softening.

Under the repeated tests of Zhang Shouqing and others, this coating was not scrapped even when the N furnace quartz crucible was opened. None of them knew what the limits of the quartz crucible were after this coating!

It takes three days for a furnace of monocrystalline rod to be lifted from the beginning of January, and Zhang Shouqing and his people have been busy in the monocrystalline furnace workshop since the beginning of January, and the Spring Festival is coming soon.

On February 2, Zhang Shouqing found Lin Qiangsheng and wanted to talk to him with a serious expression.

Lin Qiangsheng invited Zhang Shouqing to sit on the sofa and asked with a smile, "What does Zhang Lao drink?" ”

Zhang Shouqing waved his hand and said, "I'm not busy." I'm going to talk to you about something important! I would like to report your situation to my superiors, especially the hot screen device and the barium hydroxide coating material, these two technologies can greatly improve the level of semiconductors in my country! ”

Zhang Shouqing looked at Lin Qiangsheng and asked seriously: "Comrade Xiaolin, are you willing to contribute these two technologies of yours to the country?" ”

Lin Qiangsheng heard that Zhang Shouqing was originally for this, he thought about it and said to Zhang Shouqing: "Thank you, Professor Zhang!" I thought you would report directly to your superiors when you learned about these two techniques, but I didn't expect you to come and ask me! ”

Zhang Shouqing's face was impressive, and he smiled: "Originally, I really had this idea, and the report was ready, but doing so will make me restless!" I still think it's better to tell you about the pioneer, whether you discovered it or invented it, in short, we learned the technology from you, so I'm going to ask your opinion now, I think you, a little comrade, understand the righteousness and won't care so much about the country! ”

After Zhang Shouqing finished speaking, he looked at Lin Qiangsheng with a slightly nervous face, although he felt that this kind of contribution to the country was a matter of course, but after all, Lin Qiangsheng's strength was not small and he was a foreign businessman, and if he was held accountable, it would be ugly for anyone at that time. Besides, Zhang Shouqing didn't want to do things to that point, he didn't spend a penny in the hospital for more than half a month a while ago, and he relied on the expenses provided by Lin Qiangsheng and imported medicine to recuperate, and he owed a lot of affection to others.

Lin Qiangsheng nodded and said: "I put these two technologies in front of you, I didn't mean to hide the country, and many of my studies have been carried out with the development of domestic semiconductor technology." You can report to your superiors, and I'm looking forward to coming to my semiconductor lab for some researchers, and you can see that I'm in dire need of research talent here! ”

Lin Qiangsheng revealed these two technologies to the country through Zhang Shouqing also has his own ideas, that is, to improve the domestic semiconductor technology level to the same level as developed countries as soon as possible.

As long as the domestic technology is improved, it will not become a dumping place for low-grade semiconductor technology from Japan and South Korea when the country opens on a large scale in a few years. Attacking others is to strengthen oneself, Lin Qiangsheng not only wants to enhance the strength of domestic semiconductor technology, but also to enter this industry on a large scale to compete with Japan and South Korea!

"Good! I feel that you, a little comrade, are not ordinary, and you have made great contributions to the development of domestic semiconductor technology by handing over these two technologies to the country. Don't worry, after my boss Zhang reports to his superiors, if they leave you alone, I won't agree! Zhang Shouqing stood up and said loudly to Lin Qiangsheng.

After Lin Qiangsheng got permission here, Zhang Shouqing hurriedly returned to the University of Technology, and immediately reported to the Shenyang Institute of Metal Materials by phone, and the director Li Xun also attached great importance to the news.

Zhang Shouqing actually got a coating material for quartz crucibles from Lin Qiangsheng, so that the quartz crucibles that could only pull a few furnaces reached nearly 10 furnaces and were not broken, and the quartz crucibles showed no signs of softening at all.

"What? Monocrystalline furnace insulation cover? Li Xun as an expert in metal materials, has also studied and manufactured single crystal furnace equipment, he knows the shortcomings of the open single crystal furnace, Lin Qiangsheng actually creatively made a lid to cover the open single crystal furnace to greatly increase the temperature of the single crystal furnace, although this method has been proposed before, but the domestic temperature control problem can not be solved, so give up.

"Lao Zhang, I will immediately contact the Institute of Semiconductors of the Chinese Academy of Sciences, you will be stationed at Lin Qiangsheng in Bincheng, I estimate that the people in the capital will arrive in a few days!" Li Xun immediately said to Zhang Shouqing.

Zhang Shouqing assured on the other end of the phone: "I am in the production workshop, not leaving an inch!" (To be continued......)
