Rebirth of Northland Technology

Microelectronics Lab, Monday morning

Zhang Qun came to the door of the laboratory on time and found that there were not many people around the door.

"Why are there only three of you today, other students, are you still coming?" Zhang Qun opened the door and greeted a few students.

"You are the only girl here?" Zhao Weiwei had the same problem.

There was a large group of people last week, and today I am alone, the contrast is too great, and it makes people feel uncomfortable.

"Class has started! They are all going back to class!" Hao Yunli asked her classmates to ask for leave for her.

When she made up her mind in the morning, she was very happy, looking at the empty corridor in front of her, she was also a little nervous.

In eighteen years of life, this is the first time to ask for leave for class!

"What about you? The boy is not here? Where are your fellow villagers?" Zhao Weiwei turned to the younger brother.

"How do I know this?" Cheng Yongxing shrugged with a wry smile on his face.

"Go, go in! There is no one else."

Things are pretty good!There was an accident right there.

The women's volleyball team and the Boy Scouts were all in vain.This feeling is sour!

"Have you brought the layout?"

"Bring it." Senior Sister Zhao handed over the prepared floppy disk.

The three kittens followed Teacher Zhang's ass, step by step.

————————————————

Zhang Qun is very similar to the operator that Cheng Yongxing saw in the laboratory of later generations, and he played very well with various equipment.With him, the use and operation of the equipment is not a problem.

But this project, for him, the real purpose is to knock on the door of the semiconductor industry.This is an excellent training session.In the future, there will be some things that he can only do by himself, and he can't fake his hands.

In other words, when will he be able to become a teacher, and when will this project end!

Some time ago, he went on the computer with Senior Sister Zhao, and he had explored the software of this era. Now it's the highlight, the film!

"Mr. Zhang, let me do it this time." Just as Zhang Qun took out the wafer from the cabinet, Cheng Yongxing proposed next to him.

"can you?"

"No, you have to do it! There are many more in the future, and you can't always count on you, teacher! Moreover, I can use it myself. It is convenient to have an extra class at night?"

Cheng Yongxing showed a serious and studious look.

"Or, I'll come?" Zhao Weiwei was still a little worried about the juniors who had only two days of training experience.

"It's okay! The three of us, I'm the only man, who am I not going to be on?" Cheng Yongxing didn't care, pushing the senior sister aside carelessly.

The two girls can only smile to each other.the man?He is the youngest!

"Wait a minute, you took the wrong solvent!" Zhao Weiwei quickly reminded her.

"Really?" Cheng Yongxing glanced at the notes, and didn't write this paragraph clearly, so he hurried back and added the content.

"Let's watch it together!" Hao Yunli also came over with a notebook.

"Okay, this is the first operation, let's be careful together! The first time I will come, the second time, you come."

If time permits, Cheng Yongxing's free labor should also go through it again.

There is nothing to say about the process of tape-out, every step is a rule to follow.As long as the operation is step-by-step, practice makes perfect.

In this way, in the midst of stumbling, the three of them turned around under the guidance of Teacher Zhang.

After two days of training, slowly, the sense of unfamiliarity gradually disappeared, and the courage gradually grew.

————————————————

The tape-out procedure has been standardized, but the steps are cumbersome.As for the work intensity, it's really not big.It's just that this is the first time I have done it, and everyone is a little nervous.

Soon, a group of people came to the lithography machine.

"What kind of pattern are you?" Seeing the layout for the first time, it was different from what Hao Yunli understood.

It stands to reason that whether it is an acceleration sensor or a gyroscope, the pattern should be very complicated.

"It's the first time to draw a picture and tape out a film. It's always necessary to rehearse and practice hands!"

"Today's operation is just training hands?" Hao Yunli didn't think much.I listened to my classmates.Believe that it is true, the mood is relaxed.

What Cheng Yongxing brought is a cantilever beam pressure sensor. The solution is very simple and the process requirements are not high. It is very suitable for the current situation of the laboratory.As an entry-level practice, it couldn't be more suitable.

But on the other hand,

Although this cantilever beam structure is simple, in later generations, it can be regarded as famous.

This structure, like a jack of all trades, has a wide range of applications.This structure can measure pressure, temperature, magnetic field, acceleration and other variables.

Behind the simple shape, the paper that can be extended is in units of hundreds and thousands!

"However, these patterns are a little strange, why do they seem to be the same, but a little different?" The girl's eyes are still sharp.

"I drew several shapes in different sizes at the same time. After I made them, I actually measured them to lay the foundation for the subsequent design."

Generally speaking, the various structural dimensions in the drawings are the result of careful design by the designer.The various stresses and deformations can even be simulated in software. Once the three-dimensional structure is formed, the distribution of various forces, the expected deformation, and even the current intensity and temperature distribution are all clear at a glance.

At this stage, there are very few materials and mechanics related to the strength of semiconductor materials. This is the first aspect.The second aspect, a large number of derivations of mechanics and materials science, without the aid of computer software, has become a massive computational workload.

If all these tasks are done manually, and given him another year, he may not have a chance to finalize the draft.Cheng Yongxing did not have the ability to deduce, nor the patience to go through the information.
