The Immortal Warrior: From Reverse Engineering to Forging Swords for the Country

Chapter 27 0.25 micron CPU was rubbed out by hand
  Saying goodbye to Zhang Zhipeng, Zhao Min walked briskly towards the Department of Computer Science.

Her feet felt like they were stepping on clouds, and every step was like stepping on a beautiful note.

Her mood was like a flower gradually blooming at this moment, and she felt that everything in front of her was so beautiful.

Returning to the Computer Department, Zhao Min went directly to the office of the department director Wang Zhongxue.

Knocking on Wang Zhongxue's office door, Wang Zhongxue saw Zhao Min and smiled and said, "I told you I was looking for you, so you came here yourself."

Zhao Min smiled and asked, "What can I do for you, director?"

Wang Zhongxue said: "Academician Zheng Jingzhi from the Department of Aircraft Engineering called me and said that he is working on a major national scientific research project and now needs your assistance."

"Academician Zheng values ​​you so much. This is the honor of our computer department!"

"This department will try to arrange as few courses for you as possible in the future. From now on, you should focus on academician Zheng's research project."

Zhao Min was a little surprised.

She really didn't expect that Zheng Jingzhi would take the initiative to greet Wang Zhongxue for her.

This shows how important Zhang Zhipeng is in the mind of teacher Zheng Jingzhi.

Zhao Min hurriedly said: "Thank you, Director Wang. I will follow the arrangements of the leader and the school."

"Here! Teacher Zheng wrote a special document for me to bring to you."

Zhao Min handed the paper signed by Zheng Jingzhi to Wang Zhongxue.

Wang Zhongxue took it over with a smile and took a look at it and said, "With this thing, it will be easier to handle."

"Xiao Zhao, I see you are in a good mood today. Is there any happy event?"

Zhao Min smiled and waved his hands and said, "No!"

"I'm actually in a good mood every day."

Wang Zhongxue nodded and said: "Young people should maintain a high-spirited and optimistic attitude!"

"If you go to help them with this project, you must devote yourself wholeheartedly!"

"It's not easy for the country now! In terms of fighter aircraft, we are indeed lagging behind the world's advanced level."

Wang Zhongxue encouraged Zhao Min.

Zhao Min naturally expressed his determination repeatedly.

Wang Zhongxue said with a smile: "You are about to evaluate the lecturer, right?"

"In terms of scientific research results, you must be prepared! Try to get it right in one go!"

Zhao Min said: "Director, I have published a few papers. I will try to publish another paper in a core journal as soon as possible."

In colleges and universities, scientific research performance is very important, even much more important than teaching performance.

No matter how well you teach, if you don't have papers or topics, you can't even think about getting a higher professional title.

Wang Zhongxue nodded and said with a smile: "Come on! You can take advantage of the opportunity of participating in Academician Zheng's project to write a few papers."

"Don't be embarrassed. When you have the opportunity to add your name to the thesis, don't miss it, you know?"

Zhao Min thought to himself, I can't be too unscrupulous in order to publish a paper, right?

If others are willing to take me, that’s fine.

But Wang Zhongxue also had good intentions, so she could only say yes with a smile.

Zhao Min chatted with Wang Zhongxue for a few words, then she said goodbye and left.

Zhao Min looked at the time, it was almost 3 o'clock in the afternoon.

She rode her 26 Phoenix bicycle straight to the aviation laboratory building.

At this time, Zhang Zhipeng's laboratory was already very busy.

Zhang Zhipeng already has basic skills and experience in the operation and use of photolithography machines.

He personally operated the photolithography machine and exposed the silicon wafers.

During this process, his experience bar was also increasing rapidly.

[Congratulations to the host, you have mastered the basic skills of using a deep ultraviolet lithography machine to manufacture 0.25 micron chips! 】

[Congratulations to the host, you have mastered the intermediate skill of using a deep ultraviolet lithography machine to manufacture 0.25 micron chips! 】

Zhang Zhipeng calmly and skillfully operated the small projection-type deep ultraviolet lithography machine he had used, exposing the silicon wafer under the lens, and watched the circuit diagram appear on the silicon wafer bit by bit. The mood is simply wonderful.

Others are not idle either and are busy with other matters in the laboratory. Just when Zhang Zhipeng was finishing processing the first 8-inch silicon wafer with a photolithography machine, Zhao Min walked in.

She saw that there had been considerable changes in the laboratory at this time.

A dust-free area has been specially set up in the laboratory for chip manufacturing.

This area is isolated with a transparent air mold, and the ventilation system uses a fresh air system made by Zhang Zhipeng himself. , and also used filtering devices. These things were also built by him, Tian Hongtao and others.

In order to create such a dust-free space, Zhang Zhipeng also put a lot of thought into it.

Zhang Zhipeng saw Zhao Min in the dust-free space. He smiled and waved to her, indicating that she could observe in the laboratory first.

Zhao Min also responded with a smile and asked him to busy himself, and she would do what she could in the laboratory.

Zhang Zhipeng continued to be busy in the dust-free space.

After the chip is developed by photolithography, it must be etched. After etching, ion implantation must be performed. Finally, pin testing must be performed to detect the electrical characteristics of the grain, etc.

The work is quite complex.

The whole process was completed by Zhang Zhipeng himself.

Before I knew it, a few hours passed.

All the work went smoothly.

During the busy process, Zhang Zhipeng's experience bar was also increasing rapidly.

[Congratulations to the host, you have acquired the advanced skills of using a deep ultraviolet lithography machine to manufacture 0.25 micron chips! 】

[Congratulations to the host! You get the entire process flow for manufacturing a large-scale deep UV lithography machine! 】

[Congratulations to the host! You get the entire process flow for building a large etching machine! 】

[Congratulations to the host! You get a complete process flow for manufacturing large-scale automated chip packaging equipment! 】

……

I was indeed a little nervous.

However, Zhang Zhipeng felt quite happy listening to the system prompts in his mind.

After he finished packaging the CPU that he had rubbed with his hands, he looked at the time and saw that it was already past 9 o'clock in the evening.

Only then did he realize that there were already many people standing outside the dust-free space.

Even the principal Dong Haoming is there. And Zheng Jingzhi stood next to him.

Zhang Zhipeng smiled and waved to the people outside. He put his packaged CPU into a prepared small box covered with soft cloth, and walked out of the dust-free space.

"How's it going? Is it done?" Zheng Jingzhi asked eagerly.

Zhang Zhipeng made an OK gesture and said with a smile: "It's made."

"However, we still need to conduct tests to know how effective it is."

Dong Haoming smiled and said, "Then let's test it."

"Let's see what the effect is!"

Zhang Zhipeng said with a smile: "I'm still a little nervous at the moment."

"I don't know what this thing I made is like."

"However, its manufacturing process has reached 0.25 microns, and its number of transistors is 600 million."

"This is already the most advanced chip manufacturing process in the world."

Tian Hongtao was very excited and said with a smile: "In other words, can our chip technology be said to be leading the world?"

Zhang Zhipeng nodded and said, "You can say that, but this is just a laboratory process, and it will take some time before large-scale mass production."

Dong Haoming smiled and said: "As long as the laboratory can make it and the process is improved, mass production will be very fast."

"I'm really excited at this moment, haha!"

"CPU is indeed a foundation for the electronic information industry. If this can be overcome, the development of our electronic information industry will no longer be constrained by the West!"

"The most important thing is that our aircraft avionics system should be guaranteed!"

Next, under the watchful eyes of principals Dong Haoming and Zheng Jingzhi, Zhang Zhipeng conducted a test on the performance of the CPU he had just rolled out of the laboratory.
