After going around in circles, Zhao Ye realized that before he could develop three-micron technology, he had to work down-to-earth to create an intermediate stage.
Directly moving to three microns currently faces too many problems. It’s not that it’s impossible to do it, but even if it is done, a series of devices will not be able to support it in terms of application.
This is like increasing the speed of a train. It does not mean that your train engine is powerful enough. If you want to run fast, the design of the carriage, bogies, wheels, rails, curves, lines, etc., must meet the requirements of the speed increase.
The last requirement is sufficient. If these things are not supported, it is not enough for you to have only one engine.
The second generation of lithography technology is now very mature.
The semi-automatic operation keeps the yield within an acceptable range. Now Zhao Ye looked at the equipment in the laboratory and thought of an opportunistic method. To put it bluntly, it was to replace the current dry etching.
Becomes wet etching.
To put it simply, the silicon wafer to be irradiated is immersed in water.
Water is a transparent liquid, pure water, and its refractive index is fixed at a certain temperature. Then put the silicon wafer into 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 around 5 microns.
With this process method, Zhao Ye can have certain advantages in future technology upgrades.
The idea is good, but it is also very difficult to implement 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 refraction angle will appear to 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 sealed container, so as to avoid errors caused by fluctuations in the liquid.
However, this also has its disadvantages. First, it is inconvenient to operate and low in efficiency. Second, the container used for sealing can itself be regarded as a set of lenses. Its purity and refractive index are also irregular.
If you can make glass with perfect purity and refractive index, then you can just use it as a lens set. 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 then adding a cover to it is like taking off your pants and farting, which is unnecessary.
Zhao Ye squatted alone in the laboratory, staring at this equipment in a daze for many days.
Many people around him didn’t know Zhao Ye very well and were very curious about his research style.
But these people are destined to be disappointed. Zhao Ye just squatted like this in front of everyone, without any unnecessary behavior.
Neither Zhao Ye can be seen doing calculations, nor Zhao Ye can be seen drawing drawings. Everyone can't help but have bad guesses about Zhao Ye's behavior. That is to say, his halo in the past was too dazzling, otherwise people who say weird things will definitely be inevitable.
of.
After a few days like this, people who came to work early in the morning found that Zhao Ye finally stopped staring at the lithography machine.
Because he had dismantled the machine to pieces. The various parts were placed on a canvas.
"Deputy Director Zhao, why did you dismantle this equipment? This is used for experiments. This is the only one we have in Laboratory No. 8!" Seeing such a scene, a small leader came over and accused him.
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 you. I'll take the responsibility and you don't have to worry about it." Seeing that the man wanted to say more, Zhao Ye finally couldn't help but interrupt him.
"Deputy Director Zhao, we can no longer carry out today's experiment. It is not our responsibility to fail to complete the task schedule!" The little boss immediately said.
"Well, I understand. You can go and do your work. In addition, I know your experimental tasks. In this way, your team will write a summary report today, and you don't need to continue with that experimental task. I will give you a new task in a while." Zhao
Ye's words were even more rude. To put it bluntly, that person was just a team leader and 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. However, since he has come here and obeys the superior management and work arrangements, this is the minimum requirement. It is not impossible to do this.
Sorry, Zhao Ye is the top leader here.
The team leader who spoke was a little petrified on the spot. To be honest, they have been doing the experimental tasks for less than half a year. Not to mention smooth sailing, at least the ideas are already there. The rest is to wait for time and do verification.
Until the best solution is selected.
But now, with a single word from Zhao Ye, all their hard work over the past six months has been wasted.
It is true that Zhao Ye is the leader, but they also have a temper!
"Deputy Director Zhao, our team needs an explanation! You can't just stop our experimental work casually, this includes us..."
"Okay, okay, I know what you want to say. It includes your hard work for more than half a year, right?" Zhao Ye was a little irritated by being said. He put down the work in his hands and stood up, casually writing on his desk.
Picked up a stack of documents and handed them to the other party.
"This is the experimental result I made. The formula and production process are all written on it. I'm confused. You guys 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 mess around.
of?"
The team leader did not speak, but took what Zhao Ye wrote and read it carefully.
To be honest, he didn't quite understand it.
But you can't show it if you don't understand it! He pretended to be serious and flipped through the information given by Zhao Ye page by page.
Zhao Ye glanced at him and continued busy with his own affairs.
After Zhao Ye had been going on for a while, the man came over again.
"Deputy Director Zhao, we have just verified the plan you gave us. To be honest, we think this plan is completely unfeasible."
"Have you done a verification experiment?" Zhao Ye said this to the other party while busy with what he was doing.
"Yes."
"Is it done so quickly?"
"Well! It's not very difficult to verify this."
"Oh, then let me ask you, which catalyst did you choose?"
"Huh? Catalyst?" The team leader was stunned for a moment. He didn't expect that Zhao Ye would ask him for details, mainly because he knew the details. There was only one person in the entire chemistry team who could do the experiment, and that person was not him.
.
"Yes, which one do you use?" Zhao Ye was still busy with what he was doing while talking to the other party.
"Let me ask about this!" The group leader held it in for a long time before he came up with these words.
After saying that, he turned around and left.
"Wait, did I let you go? You are the leader of the chemistry team. Now if I ask you about the experimental process, who else are you going to ask? You can't even do experiments, right?"
"I, I don't know how to do experiments, but, I am an administrative cadre, 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 looked at the financial records. You receive laboratory experiment allowances every month, as well as various laboratory subsidies.
, then I want to ask you, as an administrative cadre, why do you want to receive this subsidy allotted to front-line researchers?"
"Deputy Director Zhao, although I am an administrative cadre, I also work on the front line! The subsidy I receive has been approved by the factory." the team leader argued.
"Haha, that makes sense. But that was the previous practice. Now that I am in charge of the laboratory, this rule needs to be changed. In the future, you will either participate in the experimental work or you will not have to enter the laboratory. I have never
I have never seen an administrative cadre receive the laboratory subsidy that only researchers can receive with such shame."
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 the person behind him was. If he dared to mess around in his laboratory, Zhao Ye would definitely not be able to keep him.
"You have crossed the line, Deputy Director Zhao. My work arrangements are decided by the factory committee, not by you, Deputy Director Zhao." The team leader didn't know at this time that he was being targeted by Zhao Ye! But he was
He believed that Zhao Ye would not refute Deputy Factory Director Li's reputation.
"Since the factory committee has decided on your work arrangement, you can go to the factory committee to get your new job now."
While they were talking, a voice sounded from behind them.
Zhao Ye didn't even turn around, but he already recognized the voice of Commissioner Zhang.
Who is Commissioner Zhang? After just listening to a few words, I knew that he was a guy who was just pretending to be someone.
If such people enter the laboratory, no wonder the output of this laboratory is getting worse and worse.
"Director Li, I..." The team leader did not know Commissioner Zhang, but he knew Deputy Director Li who was now behind Commissioner Zhang.
He was about to say a few words, but Deputy Factory Director Li immediately interrupted him and said: "Team Leader Qian, you go and hand over the work now, and then report to the factory committee."
"Ah! Me." Team Leader Qian was so surprised. What happened to Deputy Director Li? Why did he pretend not to recognize him?
"What's wrong with you? Is there anything else?" Deputy Director Li interrupted the other party again. He was extremely annoyed. Why didn't he see that this guy was so stupid before?
Under the murderous gaze of Deputy Factory Director Li, Team Leader Qian finally realized something and hurriedly got out of the group's sight, running to who knows where.
"Zhao Ye, how are you? Do you have any ideas?" Commissioner Zhang spoke in a rather friendly manner.
"We have some, but Commissioner Zhang, I can't drive a few nails even though I'm covered in iron. We are too short of manpower now."
"Short of manpower?" Commissioner Zhang looked around, looked at the circle of people standing around, and then turned his attention to Zhao Ye. It seemed that he meant, aren't these people?
