I am a great scientist

Chapter 74 Etching Machine Development
Lithography machine is also known as mask alignment exposure machine. The commonly used lithography machine is mask alignment lithography. It is the core equipment for manufacturing large-scale integrated circuits. At the beginning of each chip's birth, it must be forged by lithography technology. To put it simply, the lithography machine is to 'imprint' the engineer's design on the substrate material-silicon wafer, and integrate billions of transistors in a square inch of 2-3 square centimeters.

The silicon wafer processed by the photolithography machine is "marked" and then processed by an etching machine. The waste part on the discarded "silicon wafer" is removed through chemical reaction and physical impact, and then undergoes certain packaging processes, and the magic silicon wafer material becomes waste. Treasure, into a valuable - electronic chips.

Because of Zhou Xing’s relationship, 5nm-level etching can be expected to be mass-produced, and the lithography machine has become the top priority of everyone. If the lithography machine makes a breakthrough, then the chip field will break through the blockade of Western countries just like the high-speed rail field. Complete the curve overtaking.

"But what? Tell me something quickly, don't keep it up." Professor Yan stared at Zhou Xing, and asked urgently:
"I have studied the lithography machine, but I have no other ideas for the time being." Zhou Xing glanced at Professor Yan and said lightly:

Hearing this, the faces of all the people present relaxed, revealing expected expressions, and a trace of regret on their faces, with complex expressions.

The mass production process of the 5nm etching machine was overcome by Zhou Xing. If even the photolithography machine was also broken by Zhou Xing, then his research and development capabilities would be too scary.

The lithography machine is much more complicated than the etching machine. The core of the chip is the lithography machine, and the core of the lithography machine is the lens. At present, the mainstream lithography machine in the world is still the deep ultraviolet invasive lithography machine. The limit of this technology is 14 nanometers. The lithography machines above and below 10 nanometers need to use extreme ultraviolet lithography (EUV) technology. Even if foreign giants are still in the stage of developing from laboratory to commercialization of this technology, the huge gap like a gap cannot be easily bridged. of.

While everyone was disappointed, they also took it for granted.

"No other ideas for the time being? You mean you still have ideas?" Unlike others, Professor Yan paid special attention to Zhou Xing's answer, and asked step by step:
"Mr. Yan, let's take down the mass production process of the etching machine first! Research and development, you have to take it step by step, don't be so ambitious!" Facing Professor Yan's probing eyes, Zhou Xing smiled mysteriously, avoiding the seriousness Say:

With Zhou Xiaozhi as an auxiliary tool for research and development, and a high-quality research environment as virtual experiments, the system tasks have not yet been settled. If necessary, it is difficult to develop an extreme nanoscale lithography machine. However, you still have to control the rhythm, otherwise you will be caught "Relevant institutions" grabbing slices for research is not worth the candle.

"You are as cunning as a ghost, you must be thinking of other ghosts in your mind!" Professor Yan stared at Zhou Xing in disbelief and said:
"Okay! Old Yan, stop embarrassing Xiaoxing. When the time comes, what should happen will happen naturally." Professor Fang looked at Professor Yan dumbfounded, and interjected:
"Yes, the matter at hand is more important now, so let's quickly try out this new etching machine." Professor Xu said energetically:

"By the way, Lao Yan, haven't you reported this matter to Director Zheng? You should communicate with him quickly." Professor Liu suddenly thought of something, and reminded Professor Yan:

"Well, I'll notify him right away." Professor Yan was stunned for a moment, then quickly picked up his mobile phone and went to the side to make a call:
The old and stubborn Professor Yan was dismissed by Professor Liu, and the painting style of the scene suddenly changed.

"Xiaoxing, I didn't hear the system impact module clearly just now, please tell me again." Professor Hu asked Zhou Xing:

"Xiaoxing, which type of controller chip should be used, I will prepare it later." Professor Liu looked at Zhou Xing and asked:
"Dazhi, bring the drawings and drawing tools here." Professor Fang looked at Guo Dazhi and ordered, looked at the crowd and said, "Everyone, work hard, and make sure to get the general drawings tonight."

Guo Dazhi nodded, turned around and went to take the drawing tools, and everyone got busy, sorting out the data, looking for Zhou Xing to verify the data, sorting out the process, and so on.

In a blink of an eye, everyone in the laboratory dispersed and entered the development stage of the trial etching machine.

After finishing the call with Director Zheng, Professor Yan watched the bustling scene of everyone, and immediately forgot about the "interrogation" of Zhou Xing's "root", rolled up his sleeves and joined the team of developing etching machines.

The busy time is full and fast, and a week passes in a blink of an eye.

Since being possessed by the system, Zhou Xing's life has tended to be an otaku. He spends his days in the laboratory building etching machines with professors, or hiding in his room with his head covered to do research. The main theme of life is only studying.

In this state of concentration, Zhou Xing's road to scientific research has become smoother and smoother.

In just one week, Zhou Xing became the soul of the entire project team without everyone knowing it, leading the development of the etching machine.

On the afternoon of the eighth day, the spacious electronic laboratory staff gathered.

Director Zheng and a group of department leaders, experts and professors fell behind Zhou Xing, watching Zhou Xing standing in front of the LCD screen of a bare electronic equipment, "crackling" typing on the keyboard, and pouring in codes.

There was an electronic beep of "Didi...", and the power indicator light of the exposed electronic equipment suddenly lit up.

"Xiaoxing, the controller responded, the system was successfully embedded, and the self-test passed." Guo Dazhi stared at the English codes on the LCD screen, excitedly reporting to Zhou Xinghui:
Hearing this, Zhou Xing showed a smile on his face, all the steps were correct, and the success of system embedding was inevitable.

There was a commotion in the crowd, Director Zheng urged impatiently, and said: "Xiaoxing, since the system has been successfully embedded, let's start the experiment!"

"Well, senior Guo, let's release the material! I'll start the processing program and conduct a processing test." Zhou Xing looked back at Director Zheng and nodded:

"Okay! Guo Dazhi nodded and couldn't wait to send the materials into the feed port.

The material was engulfed by the conveyor belt at the material inlet of the etching machine, and then the electronic equipment made a "sizzling" sound of operation.

"Everyone, please look at the LCD screen. This is a three-dimensional image that feeds back the information data of the etching machined material." Zhou Xing turned his head and introduced to everyone:

Everyone watched with bated breath, only to see a green three-dimensional graphic displayed on the LCD screen, and the data information of a silicon wafer material surface was continuously peeled off on the left and right sides.

"The material can be processed in 7 minutes, and then the material processing result will be automatically detected. If it is unqualified, the system will make a judgment and carry out secondary processing or destruction." Zhou Xing continued to introduce to everyone:
"Did it succeed?" Director Zheng stared at the LCD screen impatiently and asked:
