Super Copy of Great Power Technology

Now the lithography machine made by the Chinese Academy of Sciences is being installed and debugged in the clean room. Due to the limited space and facilities in the laboratory, the academicians and researchers did not watch but came to the graphene chip production workshop to check the appearance and working status of the original graphene chip lithography machine.

It happened that Qiao Ruida came to Rockchip Fab for inspection today and was caught by a group of academicians. They asked all the questions they had accumulated during the manufacturing of the lithography machine. They did not expect Qiao Ruida, a young man, to help them solve all the problems. They just needed to convey the problems to the big guys behind the scenes. Yes, a group of big guys, including Academician Wang, agreed that there must be a strong R&D team hidden behind Qiao Ruida and the Ruida Group, and it is the kind that is unique in the world. It is with the support of this behind-the-scenes team that the Ruida Group has been able to launch graphene batteries, graphene chips, and even aerospace planes and many other black technology products in just a few years. As for the R&D teams that the Ruida Group has put on the surface, and the genius personality of the founder Qiao Ruida, it is just a smokescreen to cover up the existence of the behind-the-scenes team.

However, what surprised several academicians was that Qiao Ruida was really good at answering almost all their questions. With the continuous development of science and technology, the frontier scientific research field has become more and more subdivided, and the accumulated knowledge has increased. Even if you are a scientific research genius, you can reach the top of a subdivided field and push the scientific research field forward a small step if you work hard all your life. It is quite remarkable. It is based on this cognition that as early as the beginning of the 21st century, some scientists asserted that it would be impossible for a scientific research all-rounder like Leonardo da Vinci, Newton, and Tesla to be born in the new century. But Qiao Ruida seemed to break this prophecy and became the all-rounder who could not appear. In the question and answer session just now, Qiao Ruida showed extensive knowledge and deep accumulation in many aspects such as optics, mechanics, microelectronics, and materials science, which is far beyond the scope of ordinary geniuses. This made several academicians doubt their previous judgments. Could it be that the black technology products launched by Ruida Group are really the masterpieces of Qiao Ruida, a super genius, who had a flash of inspiration?

Qiao Ruida accompanied several academicians to the staff canteen and had a very sumptuous dinner together. In order to reduce costs and improve chip yield, almost all chip production lines are operated continuously for 24 hours, and employees work in three shifts. Therefore, the staff canteen also provides meals in the evening, and you can even come to the staff canteen to have a midnight snack after get off work.

After dinner, Qiao Ruida was about to drive home, but was stopped by Academician Wang again. "Xiao Da, you don't have anything to do tonight, come with me to the chip laboratory to take a look and help check. This is the first time we install and debug a graphene wafer lithography machine, and we have no experience at all. If there is anything wrong during the installation process, don't hesitate to point it out directly."

Since his own mentor had spoken, how could Qiao Ruida, a student, dare not disobey? So Qiao Ruida accompanied several academicians, put on dust-free clothes again, and entered the chip laboratory. Of the researchers, only a few older ones followed, and the others dispersed, either to rest or to go out to buy daily necessities. The testing process of the lithography machine is complicated, professional, and long. It is normal to last for ten days or half a month. These researchers must be prepared for a long-term battle in Decheng City, and some daily necessities must be purchased.

The graphene wafer lithography machine is so huge that it cannot be passed through ordinary doors. If you want to put the lithography machine into the laboratory or production workshop, you can only open the skylight and use a large crane to lift the lithography machine in. When Qiao Ruida and his team entered the chip laboratory, the staff were closing the skylight of the laboratory and testing its sealing performance. The laboratory's dust removal and air filtration systems are running at full power to restore the laboratory to a dust-free state as soon as possible. Obviously, the hoisting work of the lithography machine has been completed and the installation work is in progress.

The entire chip laboratory is only over 300 square meters, and a small graphene chip production line is installed inside. It is often used as a testing site for new equipment and new processes, and is also where the R&D team explores new processes and conducts chip flow tests. It was already past the end of the workday, and the laboratory was empty. Most of the researchers and engineers at Rockchip Fab had gone home after get off work, and only a few people volunteered to stay overtime to cooperate with the Chinese Academy of Sciences team to hoist and install the lithography machine.

From a distance, Qiao Ruida saw a huge orange-painted device placed in an empty space against the wall, which was somewhat out of tune with the surrounding white-painted equipment. In the field of mechanical equipment production, different colors are often used to mark the current R&D status of a device. For example, fighter jets in the test flight state often use orange paint as a mark (some people say that it is the base color of anti-rust paint), while fighter jets that are finalized and mass-produced usually use gray or dark gray low-visibility paint. This is probably the reason why this lithography machine is painted orange.

Around this lithography machine, there are a large group of more than a dozen people holding various tools, fixing the lithography machine, connecting various cables, synchronizing information, and integrating it into the control system of the entire production line. There are two people in charge of leading the work and directing the installation. One is Lin Mengsong, who Qiao Ruida is very familiar with. He is the technical director of Rockchip Fab and has rich experience in chip production and process technology. It is normal for him to appear here. The other person is a middle-aged man with half white hair. He is tall, thin, wearing a pair of glasses, and has the unique momentum of a scientific research expert.

"Mr. Qiao, Academician Wang, Academician Song, and everyone else, welcome to our chip laboratory!" Lin Mengsong was the first to notice the arrival of Qiao Ruida and his group, and was the first to speak and greet them.

Qiao Ruida nodded and asked, "Lao Lin, have you had dinner? You can't starve just for work!"

"I haven't eaten yet. I had lunch a little late, so I don't feel hungry now. Let's wait a little longer until the installation of this lithography machine is completed, and then go to the cafeteria for a midnight snack."

Hearing the two people's question and answer, the thin middle-aged man also looked at Qiao Ruida, pulled Academician Wang next to him, and asked curiously: "Old Wang, who is this young man? He seems to be quite familiar with Director Lin?"

"I think you can remove the word 'seem'. They are really familiar with each other. This young man is called Qiao Ruida, a graduate student of mine. He is also the richest man in China. The Rockchip wafer factory where we are is one of his industries. And Engineer Lin is the technical director of the Rockchip wafer factory. How can he not be familiar with Qiao Ruida, the big boss?" When talking about Qiao Ruida, Academician Wang's expression is always very happy. Academician Wang has been teaching and educating people all his life, and his students are all over the world, but none of them have made outstanding contributions in the field of scientific research. Before he retires, he will be able to wake up with a smile when he sleeps to receive such an outstanding genius as Qiao Ruida as his successor.

Hearing that the young man was Qiao Ruida, the thin middle-aged man exclaimed, "Ah, he is Qiao Ruida, the great man who developed the graphene chip by himself. I thought he was the same age as me, but he is actually a young man studying for a master's degree. Old Wang, your research and development ability is quite impressive, but your teaching ability is average. After decades of teaching and educating people, you haven't even trained a Yangtze River Scholar. How about this Qiao Ruida transfer to my name to study, I promise to do my best to train him into a talent." Academician Wang rolled his eyes and said, "Don't be ridiculous, classmate Qiao has already become a talent, he doesn't need to learn anything at all. The reason why he applied to be my graduate student is just because I see that the conditions here are loose and the time is free, which can facilitate him to manage the company and carry out his own research and development projects. With his level of knowledge and research and development ability, there is very little we can teach him."

"That's such a shame. Since we can't be master and apprentice, let's just be friends. Can you introduce us to each other?"

"That's possible. Come, Xiaoda, let me introduce someone to you. This is Academician Yao, who specializes in the field of mechanical precision processing and control. The double worktable on our lithography machine was developed by his team. In addition, Academician Yao has another identity, that is, he is a distinguished professor at Huaqing University next door to our school. Academician Yao, this is my student, Qiao Ruida."

The grudges between Huaqing and Peking University, two of China's top universities, have a long history, and can even be traced back to the period of major adjustments to higher education departments at the beginning of the founding of the People's Republic of China. During this period, the gains and losses and changes in status of the two schools led to competition and struggles between them. Specifically, Peking University lost many excellent disciplines and majors in this adjustment, especially its liberal arts and science majors were split and adjusted in large numbers, resulting in a decline in its overall strength. Huaqing has gained a large number of high-quality disciplines and majors through this adjustment, especially the strength of engineering has been significantly enhanced, becoming the leader in the field of engineering in China. Some of these talents came from Peking University, and the feud between the two universities was thus formed. In the following decades, the two universities have fought for talents, projects, students, and funding, and all kinds of open and secret struggles have occurred countless times. Later, there was a university ranking list, and Huaqing and Peking University fought for the top spot, and they showed their magical powers, propaganda wars, public opinion wars, strength, and data, and they were very happy.

Qiao Ruida and Academician Wang, both of whom graduated from Peking University, were destined not to be able to travel with Academician Yao, who graduated from Huaqing University. They could cooperate with each other, but forget about being close friends. When Academician Wang introduced them, he specifically pointed out Academician Yao's identity as a Huaqing professor, because he was afraid that Qiao Ruida would really be abducted by Academician Yao. Qiao Ruida is talented and wealthy, and he is also a genius in scientific research. It is not easy to find such a good apprentice. If you miss this one, there is little hope of meeting the next one in your lifetime.

"Hello, Academician Yao, welcome to Rockchip Fab to give us your guidance!" Qiao Ruida stretched out his right hand, shook hands with Academician Yao, and said.

Academician Yao smiled bitterly and said, "I don't dare to be a mentor, but I am more like being mentored. Since I came to Rockchip Fab and saw your graphene chip production line, I have been shocked. There are so many technical details, and with my shallow knowledge, I don't understand many things. Just now, I was discussing some questions with Director Lin."

The two chatted for a while, and the topic turned to the photolithography machine next to them. Qiao Ruida asked, "Academician Yao, to what extent has this photolithography machine been installed? When will it be completed?"

"The base has been fixed, and leveling and dust removal are in progress. The line and pipe connections are about halfway done, and the installation will be completed in another hour."

At this time, Academician Song, who was standing nearby, came over and asked, "Mr. Qiao, how about this lithography machine we produced? Can it catch Mr. Qiao's eye?"

"Just looking at the shell, it is almost the same as the original lithography machine. It is difficult to evaluate the internal structure because we cannot see it. After the lithography machine is installed, we will use it to process a few graphene wafers tomorrow to test the yield rate, and then we will know the true condition of this lithography machine."

As he spoke, Qiao Ruida used his mind to open the system panel in his mind, and used his eyes as a lens to take pictures of the photolithography machine next to him. Then he turned on the analysis skill, imported the photolithography machine picture, and analyzed it. The next moment, a large amount of text, pictures, and even videos poured into his mind. Qiao Ruida stood there and digested it for a long time before he absorbed all the knowledge.

Compared with the original lithography machine, the newly developed lithography machine has the same overall structure and basically the same parts and components. There are only slight differences in individual details, which are obviously the result of secondary optimization. These optimizations are good and bad. Good optimizations can speed up wafer lithography and improve the yield rate. Bad optimizations become worse and worse. One of the optimized parts can even cause the whole machine to crash under certain conditions. Isn't that amazing? In addition, Qiao Ruida also found several places on this new lithography machine where the materials were unqualified and the processing was not in place. Parts processed with unqualified materials may not cause problems in the new machine stage, but after a long period of use, the parts will age, the strength will decrease, or even be completely damaged, causing serious losses.

Qiao Ruida saw all of this, but he couldn't say it directly, otherwise it would be difficult to explain how he found these defects without turning on the lithography machine. (End of this chapter)
