Chapter 193 You, a freshman, graduated early! Feng Kaifeng and Liu Wenjie were stunned by Lu Shan's dazzling operations. Is the seemingly complicated alloy film production equipment so simple? According to the traditional memory production process, wafer preparation, physical imaging, thin film deposition and chemical reaction are required. Wafers are the basis of memory chip manufacturing. Wafers are made of silicon, and nowadays there are also wafers made of waste glass, silica and other materials. The wafer preparation process requires multiple steps such as cutting, grinding, and decontamination. Physical imaging is the process of writing patterns onto silicon wafers using a photolithography machine. The photolithography machine uses ultraviolet light to illuminate photoresist to write various circuits on memory chips. This is also known as photolithography, but the accuracy is not as high as that of chips. The chemical reactions mainly involve the etching and cleaning of memory chips. But now the process of producing memory using platinum (copper) tin and iron alloy has completely changed. It does not rely on traditional photolithography and etching technology at all, but instead completes the corresponding work through the structure of the alloy and the arrangement and movement of electrons in the metal grid after power is applied. After Lu Shan finished his work, he clapped his hands and saw the two doctoral students of Ma Zhua. He smiled and said, "You have to learn how to operate the equipment. You are the master and you will have apprentices in the future." The two of them almost burst into tears. What had gone wrong with all the extra ten years of studying they had done? But seeing that Lu Shan was still unsatisfied, the two doctoral students had no doubt that Lu Shan would really develop a brand new chip one day.
Seeing that the two doctoral students were a little confused, Lu Shan went over to give them some pointers and explained his logic, which helped them speed up. Lu Shan is not a pushover. He cannot do everything himself. How many things can he actually do? It's just a processing process, nothing shameful. We have the material preparation technology in our hands, and there's nothing wrong with making the processing process public. Even if others copy it, they won't be able to understand it. In addition to the installation of memory equipment, the factory laid water and electricity, and after laying the production lines, some personalized spraying was carried out, and BanSi Technology Company was established. Lu Shan didn't hold a big wedding ceremony. He just registered and got married. "The company has been established? Then I have to send a flower basket?" When transferring the information, Lu Shan called Zhang Lingxi. Zhang Lingxi was very shocked. Lu Shan was too resourceful. He managed the factory without saying a word. Shouldn't this kind of thing be very troublesome? "Someone has already sent a flower basket, over there!" Zhang Lingxi looked at the signature on the flower basket that had been moved aside and was shocked again. The president of Jiangzhou University, the dean of the School of Computer Science, and... I didn't read it all because Lu Shan put the flower baskets aside and stacked them, so I only saw part of the text. It's outrageous that the flower baskets sent by these school leaders were just put aside. "Is it really okay to do this? It will make people sad when they see it." Lu Shan didn't care: "Putting it at the door will block the entrance and exit, which is not good for safety." Lu Shan introduced Zhang Lingxi to meet the two doctors. The two doctors looked at each other and there was a hint of smile in their eyes. The basic team of BanSi Technology Company was set up in this way, and work started after the relevant arrangements were in place. It was already June 2009, and it was graduation season. Everyone was busy defending their thesis, singing songs, or breaking up, having abortions, or looking for jobs. Countless college students will enter a very confused stage after graduation. The work is very different from what they imagined. Some of them will take various exams when they cannot find a job. Some also try harder and plan to pursue a master's or doctoral degree, and so on. Third-year graduate students Qiao Weiwei and Ma Lijuan also have to take part in the defense, not to mention the seniors. If they fail to pass this stage, they will not get their degree certificates. On the day of the defense, Lu Shan called Gao Chuan and his roommates and said he would take them to a nice place. When these adopted sons heard the word "nice place", they followed him without hesitation.
"Aren't we going to a good place? Why are we heading towards the teaching building?" Wang Yu felt something was wrong. "Is there a new entertainment venue opened in the school?" Huang Hao, who was wearing glasses, squinted his eyes and looked a little wretched. "Lu Shan is not such a person. At least he knows that he can't go there during the day and he has to avoid it." Jiang Weida defended Lu Shan casually. Lu Shan couldn't help rolling his eyes after hearing this. It was such a good explanation. He asked him not to help explain it next time. Gao Chuan rarely talked nonsense and behaved honestly along the way, but the expectant look on his face revealed his true thoughts. "We're here!" After a while, Lu Shan brought them to a building. At this time, there were many people standing in the open space in front of the building, holding documents in their hands and looking nervous. Gao Chuan looked around and didn't recognize anyone, and the same went for his other roommates. "Where is this?" Gao Chuan finally couldn't help it. He followed them all the way since early morning, and ended up in this place? "Graduation defense for undergraduate mathematics students." "What? Then why are we here?" "Can they let us in?" "no problem." Lu Shan waved his hand, found the door, and led a few people to the conference hall in the teaching building. No one had entered yet, and there was a teacher guarding the door. The teacher took a look at Lu Shan and immediately let Lu Shan and several adopted sons in. It was not Lu Shan who wanted to recognize them, but these people took the initiative to recognize them after getting Lu Shan's review materials. The five of them found a seat and sat down. Gao Chuan was still confused. He was let in just like that? "Are we here to watch others defend their thesis?" Gao Chuan swallowed hard. "Yes, I came here to broaden my horizons. I also want to know the level of current mathematics students." Lu Shan sat calmly. The defense started soon, and one by one, the candidates went up to the stage, and those who didn't go up waited in the audience. The instructor on the stage would ask some specific questions. "My research topic is the application of commutative algebra in modern mathematics. In my paper, I discussed several mathematical theorems that might be more convenient to apply using commutative algebra..." "My thesis is about the mathematical theory of lightweight cryptography. I analyzed the existing cryptographic systems and introduced mathematical theorems that I think are better to construct cryptography..." "My thesis is about the calculation and application of Weil exponential sums over finite fields..." The thesis is basically about the application of mathematics. What new theoretical mathematics content can undergraduates in the mathematics department expect them to come up with? They are not Lu Shan! Gao Chuan and several others in the audience were stunned. They had never heard of many of the words and didn't know them. Some papers even sound good, but the supervisor asks them to revise them and defend them again. The tutors were of relatively good quality and did not directly scold students, but some students did make them feel overwhelmed. "The paper you handed in would be more valuable if there were no words on it." "Lu Xun walked from Baicaotang to Sanwei Bookstore, but you flew directly there, which is exactly the same as the derivation process of your paper." "Sometimes it's better to be brief. Have you ever considered how the paper feels when writing so much nonsense?" When Gao Chuan and others heard such words in the audience, they couldn't help but become even more nervous. "Damn it! Thesis defense is so difficult!! I must study hard when I get back and stop playing games! Otherwise I won't even get my diploma!" "Me too!"
"Me too! This is too scary. This is a criminal trial!" This is also one of the reasons why Lu Shan came here. His roommates are a bit of a waste of their lives. Although they are just casual acquaintances, Lu Shan hopes that they can be better and help him in the future. When hiring people, you always have to hire those who are familiar and trustworthy. Before I knew it, the defense was over. The Department of Mathematics is not a large department like the Department of Mechanical Engineering. The number of students is always pitifully small, and the threshold is too high. Many students who are good at mathematics will take the initiative to leave this department after they are admitted to university, and they also want to keep more hair. Only a very small number of brave (and reckless) people would apply to this department. "Students who have completed their defense, please come up to the stage and line up for photos." Teacher Jiang informed everyone through the microphone, "Lu Shan, you come over here too." Gao Chuan and his roommates were shocked. How could there be something about Lu Shan? "Did Teacher Jiang call the wrong person?" "He is indeed calling me, you wait here for a moment..." "Oh, we won't move around, just don't buy oranges." "..." Lu Shan walked onto the stage. His roommates couldn't help but wonder why Teacher Jiang called Lu Shan up. They couldn't figure it out no matter how hard they tried. Fortunately, Teacher Jiang quickly solved the mystery. "Let me introduce this student to you. His name is Lu Shan. He has published..." Teacher Jiang listed Lu Shan's achievements in detail, and there was a sense of pride in his words. This is his own student. Lu Shan’s achievements are so great that many mathematics graduate students are aware of them, but undergraduates are not very clear about them. Teacher Jiang needs to popularize them. Every time they were spoken, everyone's ears buzzed. If even one of these achievements was mine, I would be so excited that I would float into outer space. Look at Lu Shan, he acts like nothing happened, as if this is all normal. “Now, congratulations to Lu Shan for graduating ahead of schedule from his undergraduate program in applied mathematics. If you have time, you are welcome to visit the Department of Mathematics in the School of Science in the future. Let’s give him a round of applause!” Teacher Jiang led the applause, and the whole audience burst into thunderous applause. The seniors on the stage also greeted him one after another. They had heard of such a tough guy a long time ago, but this was the first time they saw him. Apart from being handsome, Lu Shan doesn't seem to be anything special. How come he is so smart? The roommates were shocked! Freshman! Graduate early! When Lu Shan returned, he was surrounded by several roommates, who asked him all kinds of questions. "You stayed out all day and didn't come back. I thought you were living with a girl!" "That's true." Lu Shan thought of Zhang Lingxi working with him on optimizing the process of renting apartments. "Ah? Be a human being! I'll feel better if you don't admit it." "Ha ha……" "I heard that you are the first student in the history of this school to graduate early in your freshman year. That's amazing. Will you stay in school after graduation?" "Yes, I still have a lot of things to do at Jiangzhou University, so I won't leave."
"Are you moving to the dorm?" "Try not to move. I'm used to it." "Will you still help us with our homework?" "As much as possible." "Godfather, please..." "You guys have to treat me." "I'll take the initiative! Teach me first." Gao Chuan signed up hurriedly. Lu Shan stayed among these roommates and felt that his mentality had become a lot younger. Humans are indeed social animals.
