Zhao Ye only stayed at home for two days before returning to the joint factory.
During this period, the nearby research institute was no longer as busy as before. Although it was still under construction, Zhao Ye could return to his "eight-room laboratory" again.
This was what Director Yang informed him, saying that Zhao Ye could start working here and he could come back at any time.
Zhao Ye said goodbye to his family and rushed to the joint factory early in the morning. When he arrived at his small world under the leadership of the security department, it was already separated by two walls.
The "eight-room room" that Zhao Ye originally chose was in a corner of the factory, but now, two more walls have been added to this corner. Next to the door of the factory, the security department is responsible for standing guard. A special guard has been added here.
house.
After entering, there is an open space in the middle, and there is also a duty room next to another door. Soldiers with guns are indeed on duty.
Zhao Ye was a little surprised. When did the security level increase? Why didn't he know?
After seeing Zhao Ye's ID, he was let in, and no one from the security department could follow him in.
Zhao Ye walked into this strange and familiar place and looked at the enclosed five-acre yard, feeling happy in his heart! From now on, isn't it my territory?
Two more rows of houses were built near the previous eight houses. It looked like there were more than thirty houses. There were several people on duty at the door of one of the houses.
When the soldiers on duty saw Zhao Ye coming, they immediately came over to greet him.
"Are you Comrade Zhao Ye? Hello, I am the squad leader of the security team here, Zhao Dashuan." The visitor walked up to Zhao Ye and saluted.
"Is there a security class here?" Zhao Ye was surprised. This is not a secret research institute, so why was he assigned this?
Zhao Dashuan did not answer, but continued: "Our task is to ensure the safety of the people here and to guard the equipment in the laboratory. Do you want to go to the laboratory and have a look?"
"Uh! Okay." Zhao Ye was confused and could only agree to go take a look.
In one of the newly built rows of houses, Zhao Dashuan took out the key and opened the door.
When Zhao Ye walked in and took a look, he immediately beamed.
This is not an ordinary house, there is a ramp extending downwards, and there are not too wide steps in the middle of the ramp for people to walk.
Going down, there is a door more than three meters wide. The door is very thick and looks like it is made of iron from the outside.
Zhao Dashuan operated and opened the door with force. He also turned on the light switch on the wall, and the inside suddenly lit up.
The entire building is made of bricks and stones, with some concrete beams and columns in some places. The overall area is only two thousand square meters, and it is divided into three passages. Each passage is more than ten meters wide and forty or fifty meters long.
Zhao Dashuan introduced that at the other end of the passage, there is another door leading to the research institute on the opposite side.
Zhao Ye did tell Director Yang before that he wanted an underground space. This is because it is difficult to maintain constant temperature, humidity and light in the current above-ground rooms. His next research direction is to process the real meaning of
The photolithography machine for the chip is much more sophisticated than the first generation he made.
Although it still cannot be separated from the scope of manual operation, the stability of the entire equipment, the natural light of the environment, the temperature and humidity of the environment, etc., must have a controllable range. If Zhao Ye thinks about it, there is no more suitable place in this era than the basement.
It’s a great place. At least the cost is the lowest.
Zhao Ye walked around in a circle, selected an area as his experiment site, and began to greet a few soldiers to help him move things.
This was originally a heavy experimental bench with the top made of natural marble. Therefore, Zhao Ye just moved some tools and equipment down.
Sitting in this basement, Zhao Ye felt really good. At least he didn't have to endure the high temperature outside. Moreover, the waterproofing here was good, and there was no feeling of overcastness.
The preparation work has been done for him in the factory, so he has to get into working condition as soon as possible.
Zhao Ye gradually sank his consciousness into the space and conducted various experiments inside.
For a scientific researcher, Zhao Ye's space skills are a priceless treasure.
He can look up information at the speed of light, construct an experimental product based on his imagination, and then conduct various experiments in front of his eyes. The experimental data can be fed back to him immediately.
His biggest task now is to determine the structure, materials, and production process of the register.
With these, everything will have a direction, otherwise, all the work of those above will be in vain.
In principle, this is not a very complicated thing. It is to "dig" a hole on the silicon wafer, then fill it with some special materials, and then fill the "filled hole"
”, cover it with a layer of insulator! This insulator can also effectively isolate the electromagnetic environment of the filling, ensuring that it can maintain its charge after the power is turned off.
Because computers are binary languages, the basis of binary is whether matter has a high charge or a low charge.
High charge represents "1", and low charge represents "0". These 0 and 1 constitute our information world, which is almost the soul and entirety of the information world.
Registers, like memory and hard disks, are used to store data. But they have huge differences in structure and function.
Not to mention the hard disk and memory for the moment, the register must ensure that the data inside is "written" and the data inside will not be "lost" when it is not powered on for a long time. During use, its access speed
It must be fast enough.
The most important thing is that the size should be as small as possible because it is arranged inside the chip.
So how can we make it smaller?
This requires the components and storage materials that make up it to be smaller!
To achieve this goal, the first generation of photolithography machines is no longer suitable.
Zhao Ye called up the model of the first-generation lithography machine in his mental space. With a thought, the "lithography machine" was decomposed into individual components.
In the previous design, the ultraviolet light used a flat-reflection design, so this time, in order to achieve smaller accuracy, Zhao Ye had to use a lens to refract the light.
This is easy to understand. In fact, after the light passes through the template, it passes through a convex lens, and then the light is refracted to a smaller range, and then hits the silicon wafer below.
Adding a lens is not a simple matter, because light will attenuate when passing through any lens. In other words, part of the light will be absorbed by the lens.
And because the convex lens is a lens with uneven thickness, the light from different positions will take different paths when passing through the lens, so after passing through, its degree of attenuation will be different. So for the bottom silicon wafer
In other words, it is the two heavens of ice and fire.
It's like cooking. The fire under the pot is uneven. Some parts of the pot will be burnt, and some parts will still be raw. The key is that you can't stir it!
So how to make the "fire" even? The answer is the lens set?
We can't just use one lens, but use multiple different lenses stacked together to balance the energy of the light.
This is still a micron-level process. If it reaches the nanometer level, the process will be completely different.
At this time, the photolithography machine and the nano-level photolithography machine can only be said to be similar in principle.
Zhao Ye has been sitting here all day today. The security personnel looked at him from a distance several times, but they didn't find Zhao Ye moving. Those who didn't know better thought that Zhao Ye fell asleep while sitting.
With the blessing of the system's capabilities and the assistance of some system materials, Zhao Ye once again used the attitude of an "experienced person" and began to write the paper.
Regarding the entire lens set, he first had to come up with a complete design plan and a theoretical paper on the plan. He had to first prove theoretically that this design plan had experimental value.
In this way, he can ask the factory or research group to cooperate with his factory to process the lenses he needs.
This is not an easy task. From the glass production of the lens to the polishing process, there are a series of problems.
That is to say, Zhao Ye relaxed the final accuracy a little. If the mirror grinding master were to process it, the yield rate would be really worrying, so he could only do it himself.
But even though there are gaps in the industrial level in all aspects of this era, Zhao Ye has not given up on assigning tasks to the factories below. This is the cultivation of the system. You may not meet the design requirements in the end, but you must always maintain technological progress.
power.
Zhao Dashuan saw that Zhao Ye had been staying here all day without moving even after dark. He was really afraid that something would happen to Zhao Ye, so he had to come over and interrupt Zhao Ye's thinking.
"Oh? What's wrong? Is something wrong?" Zhao Ye turned his head curiously and glanced at Zhao Dashuan who was standing aside.
"Oh, it's okay. I see it's getting dark and you haven't eaten all day. Do you want me to help you get something to eat?" Zhao Dashuan felt a little relieved when he saw that Zhao Ye could still speak.
"Ah! Is it already dark?" Zhao Ye wanted to get up as he said this, but after sitting for a whole day, his legs and feet were somewhat inoperable.
His body swayed, and his hands quickly held the experimental table.
Zhao Dashuan also stepped forward and gave Zhao Ye a hand. He kept reminding him to move slowly because he had been sitting for too long.
Looking at the large pile of manuscripts in front of him, Zhao Dashuan was really impressed. He was not very educated and really couldn't figure out how someone could write so many words at once.
Zhao Ye moved slowly for a while, letting his legs adapt, and then walked out of the basement.
The information was also locked in a large iron cabinet. This safe was guarded 24 hours a day and was very safe.
Standing on the ground, Zhao Ye looked at his watch and saw that it was almost nine o'clock. Logically speaking, he should go back to spend time with his family. After all, it was not easy for them to see each other again in the past two months.
But there is really not enough time. He has too much work now. He only wrote a small part of the information today, and there are more tasks waiting for him.
