"Director Tang, this is Qin Hai."

Ning Jing walked up to the half-old man and pointed at Qin Hai and respectfully introduced. Don't look at her unscrupulous in front of Qin Hai, in front of her department head, she still looks very well-behaved, although because of a few SCIs, she has won the appreciation of Tang Rongmin and some other professors.

"Professor Tang, hello, I am Qin Hai from Qingfeng Agricultural Machinery Factory in Anhe Province." Qin Hai put Tranquility's bicycle aside and locked it, then stepped forward with a smile and stretched out his hand to Tang Rongmin.

Tang Rongmin also smiled and stretched out his hand, shook hands with Qin Hai, and then said: "Mr. Qin, we have long admired you for a long time, I heard that in the past three years, the thermal spraying machine of your factory has generated nearly one billion US dollars of foreign exchange income for the country, becoming the largest foreign exchange earning project except for oil, which is really amazing." ”

"Where, where." Qin Hai waved his hand, "We're just a blind cat running into a dead mouse and taking advantage of a loophole that foreign countries haven't noticed." Since last year, the rapid rise of foreign thermal spraying technology has seized most of our market, and our factory is now facing the danger of going downhill. ”

"I think, with you Mr. Qin here, your factory will always be able to find opportunities to create brilliance again." Tang Rongmin said. He was also an old pedant, but since he became the head of the physics department, he had to be sent back and forth frequently, and over time, he also learned some ways to socialize.

Qin Haidao: "Then accept Professor Tang's auspicious words." Professor Tang, don't call me Mr. Qin, I'm just a primary school student in front of you. If you don't mind, just call me Xiao Qin. ”

"How inappropriate is that?" Tang Rongmin said.

Qin Haidao: "Suitable, very suitable." This makes me feel more comfortable, otherwise I always feel like I'm not talking at school, I'm negotiating business. ”

"Haha. Business negotiations? Tang Rongmin smiled, "Since that's the case, then I'll be respectful and obey my fate, and take the liberty of calling you Xiao Qin." Come, Comrade Xiao Qin, let's go and sit in the house. ”

The two men humbled each other. Walk towards the building. Tranquility hesitated, not knowing if she should follow. Tang Rongmin saw it and greeted him with a smile: "Tranquility, you can come together, didn't you say that Comrade Xiao Qin is your brother's good friend?" ”

"yes, he used to steal materials from the workshop with my brother." Tranquility said this to Tang Rongmin again with a quick mouth.

Tang Rongmin turned his head to look at Qin Hai, and Qin Hai quickly explained: "This is all done in the past when we were young and ignorant, and now we don't steal materials." ”

"Haha. Xiao Qin is really humorous. You are now the chairman of Qingfeng Agricultural Machinery Factory, and the whole factory is yours, whose materials can you steal? Tang Rongmin joked with a smile.

The three of them came to Tang Rongmin's office with a smile. Tang Rongmin beckoned Qin Hai to sit down on the sofa, explained to Tranquility to help pour tea, and sat down opposite Qin Hai. After greeting each other for a few words, Tang Rongmin asked, "Xiao Qin, you asked Ning Ning to make an appointment with me, saying that you have something to talk to me about." Can you tell us what it is? ”

Qin Hai replied precariously, "Yes, I came to Beijing University this time. I came to ask Professor Tang for help. ”

Tang Rongmin was a little strange and asked, "Asking for help?" How can I help you? ”

Qin Haidao: "I told Professor Tang just now that our Qingfeng Agricultural Machinery Factory made some money by producing thermal spraying machines in the first two years. But since last year, the market of thermal spraying machines has gradually been carved up by foreign manufacturers, even if we still occupy this part of the market. The price of products has also dropped sharply, and the operation of our factory is facing strict difficulties. In this case, we are considering to actively develop new products and enter new markets, so. I'm going to ask you for help. ”

"I still don't understand." Tang Rongmin frowned and said, "You are a mechanical factory, we are a physics department, and we are ...... between us It doesn't seem like there's anything going on. ”

Qin Haidao: "How can there be no intersection? Although we are a machinery factory, but the products we produce now are new material process equipment, and the theoretical basis of thermal spraying technology is physics. ”

"Uh...... Well, it can only be said that each has its own strengths. Tang Rongmin half-pushed and half-accepted Qin Hai's statement.

As Qin Hai said, thermal spraying technology is largely based on physics, and the interaction between high-speed particles and substrates is a very typical physical phenomenon. Some professors in the Department of Physics of Beijing University have a deeper understanding of the thermal spraying process than Qin Hai, but they are not qualified to actually verify this process, so they will give Qin Hai the opportunity to invent the thermal spraying machine.

Speaking of this matter, Tang Rongmin can be described as a thousand tears. There are a group of national masters in the Department of Physics, and there are enough ideas in their heads, but to practice these ideas, what is needed is a lot of real yàn. The Department of Physics has insufficient real equipment, and the real funds are even tighter, so it is impossible to support such a real thing, so we can only watch our foreign counterparts take the lead in achieving results.

This method, like thermal spraying, involves a number of interesting physical phenomena. Several professors in the department approached Tang Rongmin and expressed their hope to get a thermal spraying machine so that they could do some thermal spraying in the real yàn room to test some of their academic conjectures. But how can Tang Rongmin have such ability? He asked someone for a price, and knew that the thermal spraying machines exported by Qingfeng Agricultural Machinery Factory were more than 2 million US dollars each, which could be worth the entire funding of the entire physics department for four or five years.

"Professor Tang, we have been inspired by the development and production of thermal spraying machines, that is, the equipment related to material technology has a large market, and whoever occupies the leading position in technology will be able to win the market. Therefore, we would like to form an industry-university-research alliance with the Department of Physics of Beijing University to jointly develop advanced materials and equipment. Qin Hai said.

"Advanced material equipment?" Tang Rongmin muttered the word, showing a thoughtful expression.

"For example, we know that the Department of Physics at Beijing University is very successful in ion implantation technology, so I wonder if Professor Tang is interested in co-developing ion implantation equipment for industrial use with us?" Qin Hai threw out a mention.

"You want to make ion implanters?" Tang Rongmin was stunned for a moment, and his gaze at Qin Hai gradually became hot.

Ions can be understood as atoms that gain or lose some electrons, and are also a kind of elementary particles that make up the chemical structure. In a vacuum, if a beam of ions is shot at a solid material, it may bounce out of the solid material, or pass through the solid material, but it may also stay in the solid material. The latter is known as ion implantation.

Ion implantation means that new elements are added to the original material, which can change the properties of the original material, so it is a very important material processing method. The ion implantation method can realize the surface modification of ceramic materials, metal materials, and polymer materials, and produce new materials that meet people's needs.

Another very important application of ion implantation is the manufacture of large-scale integrated circuits in the microelectronics industry. Ion implantation of silicon wafers can be doped with various impurities in the silicon element, thereby changing the electrical characteristics of semiconductor materials, and for this reason, ion implanters have become one of the important equipment for large-scale integrated circuit manufacturing.

The Department of Semiconductor Physics of the Department of Physics of Beijing University is researching ion implantation technology, and has also designed ion implanters for several domestic electronic equipment companies. However, in addition to theoretical guidance, the manufacture of ion implanters also requires high-precision machining capabilities. Due to the limitation of processing capacity, the performance of domestic ion implanters is very far behind that of foreign countries, and foreign countries are prohibited from exporting certain types of ion implanters to China for the purpose of technical blockade, which leads to the fact that domestic semiconductor production capacity lags behind foreign countries.

Hearing that Qin Hai was interested in entering ion implantation equipment, Tang Rongmin was both excited and a little worried, he said: "Xiao Qin, how much do you know about ion implanters, do you know how difficult it is to develop ion implanters?" ”

Qin Haidao: "In this regard, I am a layman. I know that ion implanters are very cutting-edge equipment, and whether it is developed or manufactured, there is a certain degree of difficulty. However, it is precisely because of the difficulty that we plan to enter this field. The chairman said that the infinite scenery is at the dangerous peak, how can you get a high return if you don't take risks? ”

"You're right, but determination alone is not enough, the investment in the research and development of ion implanters is not a figure like 100,200,000, are you mentally prepared for this?" Tang Rongmin reminded.

Qin Hai said with a smile: "If we take out 100 million, what step does Professor Tang think we can do?" ”

"100 million?" Tang Rongmin almost couldn't believe his ears, "Xiao Qin, you're not joking with me, are you?" How can you come up with 100 million to develop? ”

Qin Haidao: "Professor Tang, you are a professional researcher, you should know that if you want to compete with foreign counterparts in ion implantation technology, I am afraid that the investment of 100 million yuan is only a little less." The goal of our factory is not to fill the domestic gap in a small way, but to directly enter the forefront of the world, so that foreigners can imitate us, not us to imitate foreigners. It is precisely because of this consideration that I have made a special trip to Beijing University today to ask the professors of Beijing University to help us realize such a dream. ”

"100 million...... Where do we start......" Tang Rongmin's tone trembled a little. If Qin Hai said one million or ten million, he would still be able to calmly discuss the feasibility, technical route, and so on with Qin Hai. But Qin Hai suddenly said an astronomical figure like 100 million, and Tang Rongmin suddenly felt empty in his mind, and he didn't know what to do. (To be continued......)
