The liquid immersion system sounds like a noun that is so ordinary that it can no longer be ordinary, but it is a new noun in lithography systems. You can think it is simple, but it takes a long time to figure out this system.

This liquid immersion system is not so easy to study, involving a series of problems such as question control, bubble removal, liquid selection, etc. Deionized water is just the simplest one.

When peers began to study what a liquid infusion system was, a new round of research by the Chongshi Research Institute was launched in full swing, all targeting wavelengths of about 50nm.

This is not a simple upgrade, and some epoch-making achievements may occur.

At the final meeting of this project discussion, facing 37 project leaders, Long Jianhua proposed, "In terms of chip production, our lithography and etching are already at the top level in the world. Even so, in the lithography process, cleaning, drying, base coating, spin coating photoresist, soft drying, alignment exposure, post-drying, development, hard drying and other processes can only be considered general level, and some even lag behind their peers; in other processes, only the packaging process is at the forefront of the world."

"Some people say that I am overestimating my ability and want to develop all chip production equipment by myself and fight against the whole world. We must know that our research institute is world-class. With such a large research institute, there are more than 10,000 talents in semiconductor research. Other countries in the world are only researching this number, so why are they not able to fight against the whole world?"

"This breakthrough is a good opportunity for us to surpass or catch up with our peers. We now have 157nm and have encountered many problems. This is our foresight and an advantage. When everyone is hesitating, we have a clear direction and we will chase after us in one go. Chase them and surpass them."

According to the negotiations between the Semiconductor Division and the Sales Corporation, not selling such lithography machines within two years has allowed me to maintain my advantage for a period of time; although 157nm is only a transitional, this idea was developed by Chongshi Research Institute and did not publish the technical lines to the public. In addition, a large number of patents have been applied for, it will take at least two years for others to develop such lithography machines.

There are two years when you can do a lot of things, and even a 50nm chip may appear.

Regarding chip production equipment, Long Jianhua only "knows" some nodes, such as the liquid immersion system, such as the next step is 50nm... What made him depressed was that after Yunyan tested 157nm, he immediately asserted that the next step was this number.

A layman is an layman, a real expert is a real expert, and rote memorization is always not as good as others' understanding and reasoning...

With a 157nm chip, Chongshi Group announced that it would upgrade home appliances, with higher automation and more convenient use, which caused great tension among all peers.

Some old customers of Chic chips immediately place an order to order such chips in order not to be left behind by Chic chips; this order will be immediately accepted by Chic chips. This order can be solved by increasing the number of equipment, and the more the better.

Some people sent orders and asked to buy such equipment. For such orders, the reply was that it would take two years to deliver the goods. They should give priority to using it themselves and make a time difference. If they are secretly researched by their colleagues, it would be very bad to pierce the layer of paper. They would have to endure the torture of the layer of paper...

After the meeting, before he could reach the office, Professor Wen Hanru came up from the stairs and said with a smile, "Professor Long, it seems that I am lucky. I met you as soon as I came."

He took two steps, stepped forward and held his hand and said, "Professor Wen, why did you come here in person? If you have anything, just say it and I'll go over."

Professor Wen Hanru is the first person to study lithography machines at Chongshi Research Institute.

The first group of people from the Chongshi Institute were from Xiangdao Huawen University, four associate professors: Professor Wen Hanru, Professor Yu Nuowei, and Bai Dongxi, Meng Fuxing, Zhang Kelan and Peng Xinfei.

There were only three teams, Professor Wen Hanru studied lithography machines, Professor Yu Nuowei studied wafers, and four associate professors Bai Dongxi studied software.

Ten years ago, Professor Wen Hanru and Professor Yu Nuowei were over 70 years old and could not keep up with their energy and physical strength, so they withdrew from the corresponding research institute and focused on attending classes in college. Later, they stopped attending classes and went home to enjoy their youth.

In fact, Long Jianhua knew what they thought at that time, because they were not as active as others and felt that they had already difficulty, so they resigned.

Long Jianhua is still very grateful to them. If they didn't resign, he would never take the initiative to ask them to leave. The reason why Chongshi Research Institute is today is that they have made great contributions.

At that time, Long Jianhua didn't know a few people outside, so he mainly focused on the development of the group and finding money. The arrival of the six of them not only brought many researchers to the institute, but the progress of the project also exceeded his expectations, which made him very satisfied.

Based on this kind of gratitude, he raised their annual salary again and again. When the two left, their annual salary reached US$600,000. They had the salary of Chinese University, received such a sum of money here, and also paid dividends for projects, and quickly became one of the rich people in Xiangdao.

On the way to the office with him, Long Jianhua joked, "Professor Wen, retired and was in a better and better mental state. It seems that family happiness can make people rejuvenate."

Wen Hanru smiled and said, "That's true. People feel refreshed when they are happy. As long as they have a good mentality, they will not get sick. Now I occasionally take on private jobs and design some equipment for some companies. I don't want to make money, I just want to use my brain more to prevent Alzheimer's disease."

Long Jianhua laughed, "This is a good method."

After asking him to sit down on the sofa, he asked, "Which gust of wind blows you today?"

Professor Wen laughed and said, "I am more than 70 kilograms, and the average wind cannot move."

After a few jokes, he smiled and said, "I am reading the news and said that the lithography machine in our research institute has made a historic breakthrough, which has made his colleagues frightened, so I want to come and have a look."

These words aroused Long Jianhua's alertness. He had been away from the institute for twelve years and had retired for five years. He had never been here, but today he came.

However, he said with a constant expression, "It's not a big breakthrough. It's just that we broke the paper in advance. If a colleague is shocked, he might be able to break it immediately and be on the same starting line as us. So, we are very vague in both press conferences and promotions to customers."

Wen Hanru smiled and said, "I have been studying the lithography machine for so long, and I have been trapped in 193nm. I just want to see the equipment after the breakthrough, which also satisfies my curiosity of the old lithography machine."

Long Jianhua laughed, "To be honest, I haven't seen the assembly process yet. You know, this is a need for confidentiality. Some things are easy to spread, so there has been listed as a confidential place. If you want to see it, you need to wait for decryption."

No matter what the situation is, he will not be allowed to see it, because he has never seen it himself. Only researchers and related production system personnel can see the appearance of the equipment; while only the dozen people in the institute can see the parts and assembly drawings.

Wen Hanru didn't want to force Long Jianhua said so clearly. He had done this here and knew that he could not force it. In the face of rules and regulations, no one would look at the face of anyone.

As the boss, Long Jianhua is so persistent and plays an exemplary role. What else can he say?
