Chapter 96 Overview
meeting room.

".The above is some of the content I have summarized during this period of time, for your reference."

Although Qu Yanqiu didn't quite understand the technical details of the paper, but after reading a lot of superficial text descriptions, coupled with discussions with Chen Quan and Huang Chuxiong, he gradually became more aware of the status quo and progress of MEMS. , with their own understanding.

"Good, really good."

Zhao Liangcai clapped his hands and walked in.He stood at the door for a while.

"Thank you."

Qu Yanqiu bowed slightly politely.

"What you said just now is all summed up by yourself?"

"Yes what's the matter?"

Qu Yanqiu's learning ability is not particularly good among engineering students, but her logical analysis ability and summarization ability are definitely top-notch.

"These contents are enough to publish a review."

"Overview?"

"Yes, a review is a summary of previous work in a certain field, which is also a kind of paper."

Zhao Liangcai thought for a while, "Well, you write them all down, I'll modify them, and then send them directly to "Semiconductor Technology". MEMS is so hot now, but there are too few related Chinese materials. Your stuff, published Very likely."

"Semiconductor Technology" is a rare good journal among Chinese semiconductor journals.

In addition to the extremely rare Chinese reviews of MEMS, even the reviews in English are mostly influenced by micro-motors and tend to be in the direction of actuators.

However, under the influence of Chen Quan, Qu Yanqiu collected information in the direction of the sensor.

In addition, MEMS technology itself is also undergoing drastic changes. Basically, new things come in every month, and the review also needs to be updated in time.

China is currently completely blank in the field of MEMS.From a certain point of view, even with Qu Yanqiu's superficial knowledge, he can be regarded as a rare expert in the field of MEMS.

"Me? I write the paper directly?"

Qu Yanqiu was a little surprised.

"Yes! You must have confidence in yourself. If you feel that searching and translating English materials is too much work"

Zhao Liangcai's gaze swept across several students, and finally stopped on Feng Yan.The few freshmen in the room, that is, Feng Yan, left a little impression on him.

Feng Yan's college entrance examination scores, not to mention the first among the 89 freshmen, are at least the top three. "Let Feng Yan help you organize and summarize the text. You two are good sisters, just right."

"Ok."

"What about us?"

Li Ji raised his hand. "What are we doing?"

"Didn't Lecturer Huang assign you any tasks?" Zhao Liangcai was slightly surprised.

"They let us read books and read materials."

"Then watch!" Zhao Liangcai got impatient.

"But there are only a few books, and there are several of us."

"Why do you even ask me this?"

Zhao Liangcai's daily work is for graduate students, and he never deals with undergraduates. "If you don't have enough books, go to the library to borrow them!"

Cheng Xing glanced around, then lowered his head.

It is also a freshman, the treatment between people, the gap is too big.

But he didn't dare to say anything, because until now, he didn't know why he was selected.

Yesterday at the Mid-Autumn Festival, the feeling I had when I met Chen Quan was gone today.

Yu Yaoying and Li Ji didn't think anything of it, because they were the direct descendants of Chen Quan and Qu Yanqiu.

There is actually only one person who has a similar sense of loss and crisis as Cheng Xing, Yun Li.She thought it was pure luck that she got into the project team.

Of course, that's exactly what happened.

engine room.

Chen Quan's drawing speed became faster and faster, and soon, the prototype of the first component was ready.

This style was shown to Zhao Weiwei, the multi-wooden comb style.

In fact, what Zhao Weiwei said is correct, this multi-wooden comb is indeed a capacitor, but it is a variable capacitor.

The wooden comb in the middle is not rigidly connected to the base. When there is acceleration movement, the wooden comb will move relative to the base, and the distance between each tooth and the fixed wooden comb teeth on both sides will change. This in turn causes a change in the capacitance value.

By detecting the change of the capacitance value, the moving distance of the middle tooth can be judged, and then the magnitude of the acceleration can be deduced.

"Well, the picture is finished, but how should these dimensions be determined?"

Looking at the preliminarily completed pattern on the screen, Huang Chuxiong both asked questions and talked to himself.

Silicon, for the first time, was used by humans as a strength building block rather than a chemical and electrical material.So there is very little information about the mechanical properties of silicon, the semiconductor material.

For example, how wide and thick should the structure between the middle wooden comb and the base, which is similar to a spring steel plate, be designed?
If the size is wrong and the intensity is too high, the sensitivity of the sensor will be too low.If the strength is too small, it will cause the sensor to fail directly, because the capacitor will be short-circuited.

In addition, micromachines are different from traditional machines that are simply miniaturized in scale.

When the feature size reaches the micron level, the characteristics of the mechanical system of micro-machines, the physical properties of materials and their responses to environmental changes are very different from traditional machines.

It is still wrong to directly adopt the performance parameters of silicon in the macroscopic world.

In addition to strength, there are various parameters such as the distance between teeth, which need to be obtained by experience or calculation.

But neither can be done now.

Huang Chuxiong's research direction is biased towards materials, chemical properties, rather than mechanical properties.

Fortunately, as always, Chen Quan always has good ideas:
"We can draw a few more data at a time and combine them. Anyway, in the semiconductor process, producing one composition is production, and producing multiple is also production. At that time, just see which combination works best."

This idea was also borrowed by Chen Quan from "his" memory. "He" probably encountered a similar dilemma.

"Smart, really smart!"

Huang Chuxiong kept patting Chen Quan's shoulder. "Young man, you have a future."

"What's promising."

After class, Lin Xiangyang just returned to the computer room.

"Let me tell you, this Chen Quan is definitely a genius in scientific research."

Huang Chuxiong was a little excited.These days, Chen Quan's performance continuously exceeded Huang Chuxiong's cognition.

"Of course, I'll know when he moves the keyboard."

On the contrary, Lin Xiangyang looked indifferent. "I have never seen any student who learns IC software on a workstation and can get started so quickly."

Second Canteen

Due to the military training of the freshmen, the fourth canteen was occupied, and many professional dining canteens were messed up.

During dinner, Chen Quan and Qu Yanqiu reunited with Luo Ningwei in the second canteen after three years.

Recalling the scene three years ago, all three of them had a lot of emotions.

After talking about the past, talk about the present.

"Chinese paper!"

When Chen Quan heard that Qu Yanqiu was going to write a MEMS review, he shrugged, "Just write it!"

"What Chinese paper?"

Luo Ningwei was taken aback.
