Rebirth: My 80s

Chapter 578 Burning Money

Zhongguancun Science and Technology Building, top floor on the fifth floor.

This place is not open to the public and serves as the design and development base for photolithography machines, an independent research and development project of Huaxia Silicon Valley Company hosted by Chen Chunxian.

After living two lifetimes, today, here, Li Jiankun finally comes into contact with a photolithography machine in reality.

The understanding of lithography machines no longer remains at the level of keyboard warriors.

There is a laboratory at the end of the corridor with a huge double-sided iron door. There are no windows in the laboratory. If the iron door is closed, it is fully enclosed.

On the right side of the room, against the wall, lies a piece of wisdom that is the result of a variety of sciences including machinery, electronics, and optics.

Its size is smaller than Li Jiankun imagined, and its precision is not as complicated as some of the pictures in his memory. Most likely because its function is not powerful enough.

This is a second-generation proximity lithography machine independently developed by Tsinghua 9003 Institute.

The whole thing looks like a cabinet, rectangular in size, the size of two wardrobes with double doors put together.

When Li Jiankun walked around and looked at him with great interest, Chen Chunxian seemed to be introducing him, or making some kind of foreshadowing, and said loudly:

"The biggest difference between the second generation lithography machine and the first generation is that the first generation uses a 436nm g-line light source, while the second generation uses a 365nm i-line light source."

He actually thought Li Jiankun could understand...

It can be seen that Li Jiankun established a professional image in his mind by virtue of his keyboard warrior skills earlier.

"However, the first-generation and second-generation lithography machines are essentially the same. They are both contact proximity lithography machines, and each has obvious shortcomings. The first-generation lithography machine is susceptible to contamination due to the direct contact between the mask and the photoresist; after the improvement of the second-generation lithography machine, problems appeared again. The new problem is that due to the influence of the air cushion, the imaging accuracy is still not satisfactory.”

Li Jiankun pretended to ask: "So?"

"Be subversive."

Chen Chunxian pointed in the direction of Tsinghua University, "I have discussed it in detail there, and also done in-depth research through superficial information collected from foreign industries. The next generation of lithography machines needs to abandon the 'contact proximity' approach. , the technological solution must be in optical projection."

Right!

Li Jiankun's eyes lit up. As a senior keyboard warrior, if you tell him how to build a photolithography machine and what subtle technologies are involved, he really doesn't understand.But he still understands the major technical features.

The name of the third-generation lithography machine is exactly called "scanning projection lithography machine".

"Do you have any R&D ideas?"

Without me providing you with something... Li Jiankun thought to himself.I plan to listen to what Lao Chen has to say first.

Chen Chunxian entered the scientific research state, as if he was having an in-depth discussion with a scientist of the same level, and said seriously: "Abandon the contact method, then we can only adopt the form of air exposure. First, we must use optical lenses to gather derived light. , improve imaging quality, and secondly use scanning technology to achieve exposure.”

Good guy!

The idea is absolutely correct!

I'm afraid you didn't steal it from Institute 9003, right?

Otherwise, after only one year of research, how could we have such precise ideas?

It really goes with the old saying, the predecessors planted trees and the descendants enjoy the shade, that is comfort.

Li Jiankun raised an index finger, "One more thing. The ultimate goal of the iteration of photolithography machines is to obtain more refined manufacturing processes. What you said above, even if it is fully realized, can only improve the yield rate. There needs to be some change in the light source, and I recommend using a laser.”

Chen Chunxian stared in surprise, "Do you even understand this?"

It's not that he didn't say anything, it was because he was afraid that the boy would be confused if he said it.

Laser, that is absolutely cutting-edge technology.

Li Jiankun smiled awkwardly and scratched his head, "I understand a little bit."

"How about you do research and development, and I'll do other things. Don't you know everything about this?" Chen Chunxian said sincerely.

He is a bit less excited about the development of photolithography machines.

why?

Even if the third-generation photolithography machine is developed today, which domestic factory can use it?

For the production of radios, tape recorders, televisions, and even telephones, second-generation lithography machines are enough for the first generation.The reality is that most factories do not use photolithography machines at all and still use the most primitive etching circuit method to produce IC (integrated circuits).

It is true that the lithography machine is better.

However, they don't seem to want to improve.

"No, no, no!" Li Jiankun waved his hands repeatedly.He knew what Lao Chen was thinking. The current application range of photolithography machines in China was quite narrow, which really made people feel unmotivated.

He had to do some work and get some blood.

<divclass="contentadv">"Old Chen, you have to understand that the core is to electronic technology as the heart is to people. You want to imitate the United States and build Zhongguancun into China's Silicon Valley to promote the development of the technology industry without electronic technology. This core will not work. The purely mechanical era will eventually become a thing of the past, and no technology industry in the future can be separated from electronics."

Fortunately, Lao Chen has also been abroad many times, and as a person who has seen the world, he cannot refute these words.

The topic returned to "laser", and Chen Chunxian agreed with his opinion, "It is indeed true. The third generation of lithography machines in the world use laser light sources and have achieved leapfrog development, pushing the minimum process to 180- 130nm, I discussed it with people from the 9003 Institute, and there is no doubt that the 248nm krf laser is used.”

After Lao Chen finished speaking, he stared at Li Jiankun without blinking.

Li Jiankun understood that there was a problem.

Even if the principle is understood, it is still extremely difficult to crystallize such a complex technology.

Sure enough, Chen Chunxian raised two fingers and said, "Currently, we are taking advantage of 9003 Institute. We can share their manufacturing factory, including downstream cooperative units, and we can buy many spare parts with money and my old face." Now there are two questions."

He paused and said: "The third-generation photolithography machine requires disruptive use of optical lenses and lasers. These two 'materials' cannot be provided by Institute 9003. In fact, they are in trouble. The superiors don't seem to want to allocate money and provide resources.”

Why not? The answer is obvious.

The honeymoon period between China and the United States...

Li Jiankun waved his hand, "Tell me, how much do you want?"

Chen Chunxian glanced at him and said, "About... 500 million."

clatter!clatter!

The soles of the big leather boots hit the cement floor painted with floor paint.

Li Jiankun staggered and almost fell over.

Although I was mentally prepared, I was still shocked by the number.

Chen Chunxian said angrily: "Have I told you before that researching and developing this thing is equivalent to feeding a gold-eating beast. If it's just a small amount of money, the higher-ups won't be reluctant to invest it. This amount is totaled, and we need to build an optical instrument." For a laboratory, a laser laboratory requires the purchase of relevant technology, equipment and technical personnel. In addition, mold opening and manufacturing of other spare parts also require large sums of money."

After thinking about it this way, it seems that it is indeed necessary.

After all, it’s all about high technology.

Li Jiankun smacked it.

Chen Chunxian put his hands on his hips and said, "Just give me a nice word, do you want to do it?"

"Of course!"

Chen Chunxian raised his right hand and stretched it out like a palm, "Where is the money? When will it be available?"

Li Jiankun thought about it and said: "Let's divide it into batches. How can we get it all at once? You don't want it all at once. I will ask someone to arrange it. Within three months, I will give it to you every cent."

Although Chen Chunxian was named as one of the scientific and technical personnel who can get rich first, if he really wants to use the savings account at once for 500 million, I'm afraid it will still cause quite a stir.

It's better to take it easy and get hundreds of thousands every now and then.

"Three months?!"

Whoops!

Chen Chunxian originally thought that if he could raise so much money in three years, it would be considered good.

"Where are you going to get 500 million in such a short time?!" Old Chen's eyes widened.

Li Jiankun's calm face showed a hint of inscrutability. He patted him on the shoulder and said, "Go ahead and wait for your good news."

Chen Chunxian read the subtext from this sentence: Comrade Chen, even today, you still know nothing about me.

God knows, he really didn't underestimate this kid. He repeatedly raised the upper limit of his opponent's ability, and he was already about to break through the sky - he was not a normal person anyway.

But God knows that he was underestimated after all.

If this is the case, with all the resources in place, it seems that it won’t take too long to produce the third-generation lithography machine...

Lao Chen's thoughts couldn't help but wander to Institute 9003 again. They had no resources, but they had been working on their second-generation lithography machine for some time. Regarding the third-generation lithography machine, they had accumulated a lot of theoretical experience. It was not a waste to just watch. ?
