"Old Zhou, although you are a professor at Huaxia University and your teaching level is first-rate, don't forget that practice is the best teacher. Things in books are far from equal to the knowledge gained from practice. The three of them were
The top students were delayed for a few years, but they did not give up. Later they came to the No. 3 Factory. They had to work until six or seven o'clock in the evening every day, studying and working, which was simply better than us.
They are still busy when they are in the research institute. Over the years, they have mastered more knowledge than an old man like me. Even you are probably not as good as young people! Huh, it makes me angry just talking about it. If this equipment had been given to us three times back then,
The factory has already studied it thoroughly. How could issues like chips be as troublesome as they are now? It’s the Jiangsu Province. Those guys are delaying things too much. They’ve delayed everything!”
When Xie Xide talked about his three apprentices, he was very excited, and when he talked about the introduction of equipment back then, he was furious. This man is a typical scientist, and he never gives face to others.
"Teacher, you praise me. We are stupid people and we can only rely on stupid methods. Otherwise, what else can we do? Just make a living for our family!"
Wang Yuan scratched his head and said.
"I don't think you are doing it to support your family... Study hard. The country is now focusing on the development of the electronics industry. This is a great opportunity that you must not miss!"
Zhou Ming said.
"Professor Xie, have you ever thought about working here?"
Liu Lang suddenly asked.
"Come here to work? What do you mean?"
Xie Xide asked.
"Professor Xie, you have also seen that this set of equipment is the most advanced equipment in our country. It can be said to be a symbol of the pinnacle of the electronics industry. As long as we understand this set of equipment, not to mention catching up with foreign advanced levels, we can at least compete with the advanced level of foreign countries."
They shorten the distance. They are all top scientists in the country. Your help is needed here. Why don't you all come here to work and figure out all these technologies in the shortest possible time!"
Liu Lang said everything on his mind.
"Haha, the little guy is quite good at talking, and he even poached other people's corners. We don't have any say in this matter. It's a matter of the organizational department. I heard that you are very energetic up there, so why don't you help us?
Tell me, if nothing else, the food here is much better than our No. 3 factory!"
Xie Xide said half-jokingly.
"Okay, I will try to talk to Minister Du Hongda!"
Liu Lang smiled slightly.
Xie Xide and others did not take Liu Lang's words seriously, and soon all their attention was focused on these components and integrated circuit boards.
The arrival of Xie Xide and the four others has greatly increased the speed of their research. The level of these people is indeed very powerful. Maybe their theoretical knowledge is not as good as Zhou Ming's, but their practical level is definitely better than that of Zhou Ming and others.
Much higher. Each integrated circuit board can tell you something, such as whether it can be done in China at this stage? If not, how to improve it? If you want to reach Wanhe's technical indicators, where should you start?
wait.
Of course, what everyone is most concerned about is the manufacturing of photolithography machines.
"The photolithography machines in the island country are already one generation ahead of us. Our era used contact photolithography machines, but this machine is already a proximity type. It creates a small gap between the mask and the silicon wafer through an air cushion, and the mask is not in contact with the silicon wafer.
With direct contact, its accuracy is twice as high as ours. The biggest difference of this kind of photolithography machine is the improvement in proofreading, and we are going to improve in this aspect!"
A few days later, Xie Xide and Zhou Ming came to such a conclusion.
This conclusion seems simple, but it is not easy to do. They opened all the lithography machines. You must know that the lithography machine is a precision instrument. Its precision is far higher than other equipment. No dust is allowed to enter inside. However,
There is no sterile laboratory here. In order to reduce the impact as much as possible, this work can only be carried out in a small, airtight room. After opening it, several people moved cautiously. They worked timidly from morning to night, and almost came out.
They were all exhausted and fell to the ground.
But no one said anything about hardship or tiredness. Everyone was in high spirits, for fear of missing any detail.
The four of them, Xie Xide, stayed at the Jiangnan Radio Factory for nearly a month. There was not a day off during this month. Everyone worked together and stayed in the workshop every day to study continuously. The same was true for people like Zhou Ming and Wang Haijun. Sometimes
They would argue so loudly over a certain point of view that they would turn red in the face. Of course, these were all technical disputes. Once a unanimous conclusion was reached, everyone would laugh heartily.
Of course, Liu Lang couldn't miss such a good opportunity. Although he was not a student studying the electronics industry, mechanical manufacturing was the foundation of all industrial industries. Integrated circuit boards also require special machine tools to manufacture. At the same time, there are many metal parts in this equipment.
Components, some of which are also very high-tech, cannot be manufactured with the current domestic manufacturing level. Liu Lang needs to find a way to solve these.
In addition, Liu Lang has basically mastered some basic electronic industry knowledge during this period, and his level may not be lower than Wang Haijun. After all, his head is close to a computer, and all the data will quickly become his own knowledge after entering his head.
A month later, many key issues have been basically mastered. According to Wanhe company's standards, the imaging accuracy of this equipment is still not up to standard. If we want to improve it again, we need to improve the light source. Now this equipment
The light generated by the excimer laser is still used as the photolithography light source. In fact, it is a mercury lamp as the light source. In fact, this method is also used in China, but the related technology has not yet reached the height of the equipment in the island country. If you want to use it in this
To improve the basics again, it is necessary to use more advanced molecular laser technology.
Fortunately, domestic laser technology is also very “awesome”.
"As early as the summer of 1961, under the auspices of laser technology expert Wang Jiang, my country's first ruby laser was successfully developed. In just a few years, laser technology developed rapidly, and various types of solid, gas, semiconductor and chemical lasers were developed one after another. Successfully developed, in terms of basic research and key technologies, a series of new concepts, new methods and new technologies such as Q mutation and rotating mirror, traveling wave amplification, utilization of rhenium series ions, free electron oscillation radiation, etc.
In terms of communication, a laser demonstration was used to transmit television images in September 1964, and a call of 3 to 30 kilometers was achieved in November 1964; in industry, in May 1965, a laser drilling machine was successfully used in the production of drawing die holes; in medicine,
1965
In June 2006, animal and clinical experiments were conducted on the laser retinal welder; in the military industry, in December 1965, a laser diffuse reflection rangefinder with an accuracy of 10 meters/10 kilometers was successfully developed. In April 1966, a remote-controlled pulse laser Doppler velocity measurement device was developed.
instrument."
Xie Xide talked about the country's development in the laser field in recent years like a treasure trove.
"I am Cao!"
Liu Lang was basically speechless when he heard these words.
