Rebirth: I carry a desktop computer inside me

At present, Asmail's lithography machine has entered the EUV (extreme ultraviolet) lithography system, and last year, the second generation EUV system, NXE: 3300B, was just released.

It has been possible to achieve a process within 22nm with a single exposure, of course, its price exceeds 200 million yuan.

Jiang Cheng was not familiar with the lithography industry in his previous life, and he is still in the process of in-depth research.

Of course, the more he learned, the more he felt that the company was supplied by the entire industrial chain (Western).

German lenses, Japanese materials, American light sources...

However, at present, the level of Hua Guo is still lagging behind.

In the entire domestic lithography machine, only Modu Microelectronics has done a little better, but it is currently mainly for packaging lithography machines.

In August last year, the SSB225/10 AM-OLED TFT circuit manufacturing was just released, but the resolution was only 2um L/S and the accuracy was 0.6um, that is, the 600nm process.

The process is backward, and the yield rate is not good.

The most important lens component among the parts, Jiang Cheng currently only sees the continuous research and development of the Ivy Light Machine; As for the double table components, Mizuki University precision instruments are currently under development.

In addition, it is said that the newly established Qier Electromechanical will carry out efforts in fluid purification and measurement and control, that is, immersion systems.

Most of them are still developed in experiments and have not yet formed a commercial possibility.

Not to mention photoresist, lithography gas, photomask, lithography machine defect detection equipment, glue development equipment and other materials and equipment.

Difficult! It's really hard!

These days, although Jiang Cheng devoted himself to the internal simulation laboratory, he carried out in-depth analysis and simulation experiments.

But he is still very unfamiliar with this outdated lithography machine.

This kind of unfamiliarity is because Jiang Cheng can't understand it.

Expertise in optics, mechanics, materials, automation, computer hardware and software is required.

Jiang Cheng is only more familiar with computer software at present, and the hardware is still ready to learn from Professor Xu Wei, as for other directions, it is really not that he has the energy to study.

Of course, when you have spare time to learn later, you can dabble in one or two.

Temporarily put away the impulse to develop a lithography machine, it is a new semester, Jiang Cheng must start a new learning and research and development process.

In terms of learning, in addition to continuing to deepen the structure of multi-dimensional pulse neural networks, it is also necessary to learn semiconductor hardware related knowledge.

In terms of research and development, Jiang Cheng needs to focus on SOC chips and lead EDA software design and development.

However, at the beginning of the new semester, Jiang Cheng was called to the office by Professor Luo Ruihua.

--- (:◎) ≡----

Professor's Office in the Department of Computer Science.

"How does it feel?" Luo Ruihua refilled a glass of water and handed it to his gray-haired professor who was watching the paper on the edge of the sofa.

A thick stack of papers, the cover is Jiang Cheng's "Model Construction and Simulation Research Based on a New Structure of Pulsed Neural Network".

The old professor slowly took off his reading glasses, "Incredible, incredible!"

"When I first saw this paper, I was also shocked for a while." Luo Ruihua sat down and sighed, "I guess this kid didn't think that this new structure he made could have much prospects!"

"Really a junior undergraduate?" The old professor raised his head and stared at Luo Ruihua.

"Good, but already studying for my PhD." Luo Ruihua suddenly became a little proud.

"You have an eye."

"Professor Zhang, he said that he wanted to send a CVPR meeting, and I was a little uncertain." Luo Ruihua came to him, the key is because of this matter.

So far, not much is known about this paper.

Professor Zhang Bai is a member of the Chinese Academy of Sciences, a professor of the Department of Computer Science of Mizuki University, and the founder of artificial intelligence in China.

He is 78 years old this year.

Zhang Bai brought back his glasses, "It's to be cautious." In the past, the reason why the pulse neural network could not be studied was that neurons were transmitted one by one in a certain sequence, which was prone to many problems. But his approach seems to have found a very ingenious solution.

Luo Ruihua nodded, "Yes, this multi-dimensional structure feels very ingenious, with both the shadow of the biological neural network and the shadow of some CNN convolutional neural network."

"We'll talk to him later." Zhang Baidao, "I have a hunch that this model has a pioneering role in the development of artificial intelligence, including smart chips." "

Really?"

Luo Ruihua was just about to speak, there was a knock on the door, and Jiang Cheng, wearing a white sweater, appeared at the door.

"Teacher."

"Xiaojiang, come in." With a little smile, Luo Ruihua beckoned and introduced him again, "This is Academician Zhang Bai."

Jiang Cheng was still wondering at the moment, and when he heard that it was Academician Zhang Bai, he stood upright at the moment, "Hello Academician Zhang, my name is Jiang Cheng." "

Giant!

What about super awesome characters!

Zhang Bai said with a smile, "Young man, it's very good." Just read this paper of yours, there are some questions I want to communicate with you.

"I don't dare to communicate, it's my honor that you can test me." Jiang Cheng's posture is very low, this old man in his seventies in front of him, even in terms of age, he has to be called grandfather.

"Can you talk about this multidimensional pulsed neural network, how did you discover or create it?" Although Zhang Bai is old, his voice is still clear.

Of course, this was created by Jiang Chengyi by simulating the operation of the computer in the body.

However, Jiang Cheng could not say that.

Jiang Cheng thought for a while and said, "I had a flash of inspiration when I was studying books related to biological neural networks and computational neural networks. Since then, I have been studying this piece.

"You use Professor Luo's computer to write an image classification program, using this multidimensional pulse network." Zhang Bai said directly.

If you listen to it, it's better to let him get started directly.

Jiang Cheng was stunned for a moment, he didn't expect this big guy to do it himself so directly, "Okay."

Luo Ruihua also gave way and let him pass.

Jiang Cheng looked at Luo Ruihua's computer, the configuration was quite good, the desktop was very simple, there were only a few icons.

Opening the compiler, Jiang Cheng quickly began to design the framework.

Professor Zhang Bai walked to the side and looked up.

When Jiang Chengbian was typing the code, he would also take the time to ask what this part was to achieve, and which piece of the paper the principle corresponded to.

True live thesis defense!

Luo Ruihua couldn't squeeze in, so he brewed tea with peace of mind.

Well, the student is mine anyway, and I can ask slowly when I have time.

More than half an hour later, Jiang Cheng preliminarily designed a simple image classification program, "Professor Zhang, because of time constraints, only one simple classification has been made, can you use the training set of my experiment?"

"Yes."

Jiang Cheng then inserted a USB flash drive and imported the training set of the experiment.

Soon, Jiang Cheng's program grabbed the pictures in Luo Ruihua's computer and preliminarily classified them.

Male and female pictures were categorized, and pictures of the same people in the images were consolidated and displayed in a single folder.

Luo Ruihua coughed lightly, "Xiaojiang, you grab my computer pictures, you have to ask me first." "

Fortunately, there are no unsightly pictures in my computer.

Most of them are just photos of meetings and events.

"Teacher, I'm sorry, it's quick." Jiang Cheng smiled.

Zhang Bai pondered for a while, and then looked at him and said, "Xiaojiang, what do you think of your paper not published in foreign conferences and journals?" "
