Rebirth of Northern Technology

Chapter 145 Practice hands

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’m 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, and she didn’t even go to class.

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 hasn’t come 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 and refreshing!

“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 all kinds of equipment. With him, the use and operation of the equipment is not a problem.

But for him, the real purpose of this project is to knock on the door of the semiconductor industry. This is an excellent mobile phone training session. In the future, there will be some things that he can only do by himself, not by others.

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. He has explored the software of this era, and now it’s the highlight, tape out!

“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 a few more later, and you can’t always count on you, teacher! Also, I can use it myself. It’s 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 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 walked 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, each 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 that 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, this is different from what Hao Yunli understood.

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

“It’s the first time to draw a picture and tape out a film. It’s always necessary to rehearse and practice your hands!”

“Today’s operation is just to practice hands?” Hao Yunli didn’t think too much. I listened to my classmates. Believe that it is true, the mood will be relaxed.

What Cheng Yongxing brought is a cantilever beam pressure sensor. The scheme is very simple, and the requirements for the process are not high, which is very suitable for the status quo 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, it can be regarded as a famous name in later generations.

This structure is like a panacea, and it has a wide range of applications. This structure can measure pressure, temperature, magnetic field, acceleration and many other variables.

Behind the simple shape, the papers that can be extended are 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 very 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 future 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 these tasks are all done manually, and given him another year, he may not have a chance to finalize the draft. Cheng Yongxing didn’t have the ability to deduce, nor the patience to go through the information.
