Hearing Gao Fan's conditions, Xu Yun suddenly gained confidence. He patted his chest and said:
"How about I treat you to three of the stir-fried dishes from the canteen?"
There are many single employees at Maplewood Research Institute, some are young people who are not married, and some are singles who live separately, so there are usually many people eating in the cafeteria.
The canteen of the institute is divided into a large canteen and a small canteen. The small canteen is responsible for receiving visitors. It also has a small frying window that can provide some high-end dishes for employees to enjoy occasionally.
In the early 1980s, it was very rare to treat guests to restaurants outside. People who got married usually treated guests to their own homes, while single workers had to go to a small canteen to buy two stir-fried snacks.
Xu Yun is a college student. He came to Maple Forest Research Institute to help, and he can only receive a small student subsidy. Compared with the employees in the research institute who receive formal wages, he is considered poor. He claimed that he would treat Gao Fan to three meals a day in the canteen.
A small stir-fry meal is considered very sincere.
"Forget it about the stir-fried dishes." Gao Fan shook his head, and then said with a smile, "Senior Brother Xu, if your mouth is dull, I will treat you to some stir-fried dishes another day. Now I have dropped out of school to start a business at home, and I still have some income, at least compared to my senior brother.
You are richer."
"I've heard of this..." Xu Yun said calmly.
"By the way, Senior Brother Xu, I'm a little interested in what your 08 laboratory is researching. Can you introduce it to me?" Gao Fan said with a smile.
"You mean photoresist?" Xu Yun was a little confused.
Hey, aren't we talking about picking up girls? Why did you switch to technical issues?
Yes, those who can enter the research institute are all technical nerds, but technical nerds also have a spring in their hearts... Well, they also need spring, okay?
You know how much courage I mustered up to come here to talk to you about Junior Sister Huang. It is very inhumane for you to change the subject like this, do you know that?
However, thinking like this, Xu Yun was really embarrassed to say it directly. According to the current trend, many universities prohibit students from falling in love, and it is not new for students to be expelled from school because of this kind of thing.
When Xu Yun wrote to Huang Chunyan, he only talked about study, life and ideals, and did not dare to mention sensitive content at all. Now if he is asked to pinch Gao Fan's neck and let him get back to business, he can't do it.
"The things we are currently working on are nothing special, they are just filling the gaps in the country. As for the technological progress, the director of our office has introduced it during the previous regular meetings. Didn't you also attend the meeting?" Xu
Yun replied somewhat nonchalantly.
The seven districts of Maplewood Research Institute are all engaged in chemical technology, and there is a lot of collaboration between the various laboratories. Technical staff from all districts must participate in weekly regular meetings, where they will inform each other of technological progress and problems encountered.
It was difficult, so Xu Yun felt that Gao Fan should have some understanding of what his laboratory was doing.
The 08 laboratory where Xu Yun works is currently researching photoresist, also known as photoresist. Gao Fan learned about this from Yun Zhongming on the first day he arrived at the institute, and secretly
An idea came to my mind.
China's integrated circuit research started very early. Almost at the same time that the United States invented integrated circuit technology, China focused on this direction and began to actively catch up.
From the 1960s to the late 1970s, global integrated circuit technology experienced multiple technological stages such as small-scale, medium-scale, large-scale, and ultra-large-scale. China followed suit and did not miss any stage.
However, integrated circuits are not an isolated technology. The manufacturing of integrated circuits heavily depends on the level of the entire industrial system, especially the level of material technology and precision processing technology.
At the stage of small and medium-scale integrated circuits, the impact of the industrial level is not very obvious. At the stage of large-scale and ultra-large-scale integrated circuits, the development of integrated circuits will be difficult without a strong industrial foundation as support.
In later generations, even an industrial power like the United States will not be able to independently build a complete integrated circuit industrial system. Instead, it must rely on the power of the entire West, such as Dutch photolithography machines, German optical lenses, and Japanese photoresists.
When the United States threatened to completely block China's semiconductor industry, some spiritual eunuchs once claimed complacently: The manufacturing of lithography machines requires hundreds of factories in more than 20 countries. If China wants to independently develop lithography machines,
It is no less difficult than rebuilding a set of human civilization.
However, by that time, the size of China as a country, whether in terms of industrial population or industrial added value, has reached the sum of the more than 20 countries mentioned by the eunuchs. In other words, China has single-handedly built
A set of human civilization.
Of course, this is a story for another day.
In the 1960s and 1970s, China was still a country with a weak industrial base and suffered from joint blockade by the two camps of the East and the West. Not to mention high-tech industries such as integrated circuits, even basic industries such as steel and chemicals were inextricably linked with foreign countries.
There is a gap of more than two generations in comparison.
At that time, although China had mastered the manufacturing technology of large-scale integrated circuits and even produced very large-scale integrated circuits with the help of imported second-hand foreign equipment, the product quality was poor, the cost was high, and it was completely uncompetitive in the market.
According to literature, in the early 1980s, the price of a certain type of domestic integrated circuit chip was 8 yuan per piece, while the price of the same type of chip in the United States was only equivalent to 24 yuan.
In the early 1980s, China had many industries waiting to be developed, but the country was very poor. Compared with industries such as steel, chemicals, electricity, and transportation, semiconductors, an industry that only wealthy countries could afford, were not on the agenda.
During this period, the country's semiconductor industry development strategy was to introduce production equipment and realize the localization of some integrated circuits, especially the localization of television chips.
However, the fear of "stuck neck" is deeply rooted in the genes of the Chinese people. While introducing a large number of equipment, China itself has not completely given up on research on semiconductor equipment and related materials.
Take the photolithography machine that has become a hot topic on the Internet for example:
In 1985, the 45th Institute of the Ministry of Mechanical and Electrical Engineering developed the first domestic step-by-step projection lithography machine based on the American 4800DSW.
In 1990, the Institute of Optoelectronics of the Chinese Academy of Sciences developed the IOE1010G direct step-and-repeat projection lithography machine. Its main technical indicators are close to the level of the American GCA8000, which was developed by the United States in the mid-1980s.
Subsequently, during the 8th Five-Year Plan, the 9th Five-Year Plan, and the 10th Five-Year Plan, corresponding research results were also published. Although China's research on lithography machines has not reached the world's first-class level, it is definitely not far behind foreign countries.
Photolithography machines are just one example of all semiconductor equipment, and the same is true for other technologies in the semiconductor field. It can be said that China is always ready to face the most severe challenges and must ensure that it has the ability to fight at all times.
