Siheyuan: The Era of Core Generation

Chapter 166 Immersion Lithography

After going around in circles, Zhao Ye realized that before he could develop the three-micron technology, he had to work out an intermediate stage in a down-to-earth manner.

Going directly to three microns, there are too many problems at present.It’s not that it’s hard to do, but even if it’s done, a series of devices can’t support it at all in terms of application.

This is like increasing the speed of a train. It doesn’t mean that your train’s engine power is enough. If you want to run fast, you must comply with the speed increase from the design of the carriage, bogies, wheels, rails, curves, lines, etc. Later requirements will do.These things are not supported, you just have an engine is not enough.

The second-generation lithography technology is now very mature.

The semi-automatic operation keeps the yield rate within an acceptable range.Now Zhao Ye looked at the equipment in the laboratory, thinking of an opportunistic method.To put it bluntly, it is to change the current dry etching into wet etching.

Simply put, it is to immerse the silicon wafer to be irradiated in water.

Water is a transparent liquid, pure water, at a certain temperature, its refractive index is fixed.Then put the silicon wafer in the water, and before the ultraviolet light irradiates the silicon wafer, it must first be refracted by the water.

As long as the direction of the mask and light is controlled, the process technology can be improved by half a step based on the existing equipment.

In this way, the previous process can be improved to about 5 microns.

With this crafting method, Zhao Ye can have a certain advantage in the future technological upgrades.

The idea is good, but it is very difficult to realize this technology.

For example, water is a liquid. When the workbench shakes, the water will move with it, and when the workbench stops, the water will not stop moving immediately.

In this way, if the light shines down, the angle of refraction will be greatly deviated due to the unevenness of the water.

So at this time, it is required that the workbench cannot be moved, or that it cannot be moved too much.

Another method is to store the liquid in a closed container, so as to avoid errors caused by fluctuations in the liquid.

But in this way, it also has its disadvantages, one is inconvenient operation and low efficiency.Furthermore, the container used for sealing can itself be regarded as a set of lenses.Its purity and refraction are also irregular.

If you can make glass with perfect purity and refractive index, then you can just make it a lens group, why use it as a container?This is superfluous.

Using water itself takes advantage of the fact that pure water is easy to process, and adding a cover to it will just take off your pants and fart, which is superfluous.

Zhao Ye squatted alone in the laboratory, staring at this device in a daze for many days.

Many people around him don't know Zhao Ye very well, and are very curious about his research style.

But these people were destined to be disappointed, Zhao Ye just squatted in front of everyone, without any superfluous actions.

Neither Zhao Ye could be seen doing checking calculations, nor could Zhao Ye be seen drawing blueprints.Everyone inevitably had bad guesses about Zhao Ye's behavior.That is to say, his past aura is too dazzling, otherwise there must be people who speak weird words.

After a few days like this, the people who came to work early in the morning found that Zhao Ye finally stopped staring at the lithography machine.

Because he has dismantled the machine to pieces.Fragments of various parts are placed on a canvas.

"Deputy Director Zhao, why did you dismantle this equipment? This is for experimentation, and we only have one in No. [-] laboratory!" Seeing such a scene, a small leader ran over and accused Zhao Ye.

Zhao Ye just glanced at the other party and didn't say much.

"Deputy Director Zhao? Did you hear me? Your attitude..."

"Okay, okay. I heard it. I will take the responsibility. You don't have to worry about it." Seeing that the man wanted to say something more, Zhao Ye finally couldn't help interrupting him.

"Deputy Director Zhao, we can't do today's experiment again, and it's not our responsibility if we can't complete the task progress!" The little boss immediately blamed it.

"Well, I got it. Go and do your work, and I know your experimental tasks. In this way, your team will write a summary report today, and there is no need to continue that experimental task. I will give you a new task in a while." Zhao Ye's words were even more impolite. To put it bluntly, that person was just a team leader, and he was not qualified to teach Zhao Ye how to do things.Besides, Zhao Ye knew exactly how he got into this laboratory.

He really has no right to let him go, but since he came here, obeying the management and work arrangements of his superiors, this is the minimum requirement.

Sorry, Zhao Ye is the supreme leader here.

The team leader who spoke was a little petrified on the spot. To be honest, their experimental tasks have been done for half a year. Not to mention smooth sailing, at least they already have an idea.All that is left is to spend time and do verification until the best solution is selected.

But now, with Zhao Ye's light words, their hard work for the past six months has been wasted.

It's true that Zhao Ye is a leader, but they also have a temper!

"Deputy Director Zhao, our team needs an explanation! You can't just stop our experimental work, which includes us..."

"Okay, okay, I know what you want to say, it contains your hard work for more than half a year, right?" Zhao Ye was a little annoyed by being told, he put down the work in his hand and stood up, casually put it on his desk He picked up a stack of documents and handed them to the other party.

"This is the result of my experiment. The formula and production process are all written on it. I was wondering, you have been working on such a simple thing for half a year, are you sure you are here to do research and development? You are not here to dawdle of?"

The team leader didn't say anything, but just carefully read what Zhao Ye wrote.

To be honest, he didn't quite understand it.

But if you don't understand it, you can't show it!He pretended to be very serious, flipping through the information provided by Zhao Ye page by page.

Zhao Ye cast a glance at him and continued to busy himself with his own affairs.

After Zhao Ye had been going on for quite a while, that person came over again.

"Deputy Director Zhao, we just verified the plan you gave. I'm being honest. We think this plan is completely unfeasible."

"You did a verification experiment?" Zhao Ye said this to the other party while he was busy with his work.

"Yes."

"It's over so soon?"

"Hmm! It's not very difficult to verify this."

"Oh, let me ask you, which catalyst did you choose?"

"Huh? Catalyst?" The team leader was stunned for a moment, completely unexpected that Zhao Ye would ask him the details, mainly because he knew the details of the shit.In the entire chemistry group, there is only one person who can do experiments, and this person is not him.

"That's right, which one do you use?" Zhao Ye was still busy with his work while talking to the other party.

"Well, I'll ask!" The team leader held back for a long time, and then popped out these few words.

When you're done, turn around and leave.

"Wait, did I let you go? You are the leader of the chemistry team. Now I ask you about the experimental process, who else do you ask? You can't even do the experiment, can you?"

"I, I don't know how to do experiments, but, but I'm an administrative cadre, so I don't need to..."

"You don't need to do experiments directly, right?" Zhao Ye glanced at him again, and then said: "But I read the financial records, and you receive the laboratory's experiment allowance every month, as well as various laboratory subsidies. , then I want to ask you, you are an administrative cadre, why do you want to receive this subsidy allocated to front-line researchers?"

"Deputy Director Zhao, although I am an administrative cadre, I also work in the front line! I received this subsidy, and it was also approved by the factory." The team leader retorted.

"Hehe, that makes sense. But that was the way it was done in the past. Since I am in charge of the laboratory now, this rule has to be changed. You will either participate in the experimental work in the future, or you will not need to enter the laboratory. I have never I’ve never seen an administrative cadre receiving a laboratory subsidy that only researchers can get with a face.”

Zhao Ye didn't save face for the other party at all. He knew that this guy had a background, and he didn't care who was behind him. If he dared to mess around in his laboratory, Zhao Ye definitely couldn't keep him.

"You have crossed the line, Deputy Director Zhao. My work arrangement is decided by the factory committee, not your Deputy Director Zhao." The team leader didn't know at this time that he was being targeted by Zhao Ye!However, he is a member of Deputy Factory Director Li, and he believes that Zhao Ye will definitely not refute the face of Deputy Factory Director Li.

"Since the factory committee decided on your work arrangement, you can go to the factory committee to get a new job now."

While they were talking, a voice sounded from behind them.

Without turning his head, Zhao Ye recognized the voice of Commissioner Zhang.

Who is Commissioner Zhang?After listening to a few words just now, I knew that this was a guy who pretended to be a fake.

Such a person entered the laboratory, no wonder the output of this laboratory is getting worse and worse.

"Director Li, I..." The team leader didn't know Commissioner Zhang, but he knew Deputy Factory Director Li who was behind Commissioner Zhang.

Just about to say a few words, but Deputy Factory Manager Li interrupted him immediately, and said, "Group Leader Qian, you should hand over the work now, and then report to the factory committee."

"Ah! Me." Team leader Qian was so surprised, what happened to this deputy director Li?How can you pretend like you don't know yourself?
"What's the matter with you? Is there something else?" Deputy Factory Manager Li interrupted the other party again. He was so annoyed, why didn't he see it before, this guy is so stupid!

Under Li's murderous eyes, Team Leader Qian finally realized something, and quickly got out of sight of the gang, not knowing where he went.

"Zhao Ye, how's it going? Do you have any ideas?" Commissioner Zhang spoke kindly.

"I have some, but Commissioner Zhang, I can't drive a few nails even if I'm covered in iron. We are too short of manpower now."

"Lack of manpower?" Commissioner Zhang looked around, looked at the circle of people standing around, and then turned his attention to Zhao Ye, as if to say, aren't these people?
