Pulse detonation engine announced for entry into the Air Force

Really successful?

Looking at the small photolithography machine that had been transformed, at this moment, Lin Haiyuan and others felt like they were dreaming.

You know, half a month ago, they never thought that Qin Xiao could really successfully transform a photolithography machine, and it only took half a month.

"Commander Qin……"

Several people roared in low voices, as if they wanted to express the shock in their hearts in this way.

However, before they could say anything, they heard Qin Xiao order:"Go, get a wafer and a designed circuit board, try it out and see if it works."

For Qin Xiao, the transformation of the lithography machine , and for the first time ever.

Whether it will succeed or not, to be honest, Qin Xiao doesn't have much confidence.

However, if he succeeds this time, it means that his idea can be realized~.

Once the transformation of the 5nm process is successful, it means that if you want to achieve the transformation of the 1nm process, you only need to develop extreme violet lithography technology, and then there will be no problems in completing the transformation of the 1nm process.

However, he also knows that extreme violet lithography technology is not so easy to achieve.

Qin Xiao is not worried about this. With his special skills, it is only a matter of time before he completes ultraviolet lithography technology.

"good!"

Hearing this, Lin Haiyuan responded, and then rushed towards the place where the wafers were placed with excitement.

After a while, he came over with a box of packaged wafers.

Turn on the lithography machine , with trembling hands, he put a box of wafers into it.

After placing the wafers, Lin Haiyuan turned his head nervously and looked at Qin Xiao:"General Master Qin, the wafers are put away."

"good"

"Start the power supply unit and perform photolithography processing on the wafer"

"yes!"

Perhaps they didn't quite understand the lithography machine before, but during this period, they saw too much, and even disassembled the lithography machine. In addition, Qin Xiao also specially explained the lithography machine to them. At this time , I have long been familiar with how to use the lithography machine in front of me.

Even better than the employees of some large factories that specialize in chip production.

Boom!

The moment Lin Haiyuan pressed the movie button, the lithography machine Then it starts up and makes a low operating sound.

At this time, the cut and polished wafer automatically enters a specific workbench, and the photoresist is evenly applied on the surface of the wafer during the rotation of the wafer.

The photoresist is applied very thinly, which cannot be done manually. The photolithography machine can be fully automated, and it has become one of the standards for testing whether the photolithography machine can produce chips.

The process of applying photoresist would not be done manually. If it is processed, it cannot be applied very thinly, and the location of the application will also vary greatly due to different degrees of manual force.

This difference may be difficult to distinguish with the naked eye, but it can For chips that require high-precision processing, this difference means that the manufactured chips cannot be applied in practice.

After the wafer is coated with photoresist, the most important step is photolithography.

The photoresist layer is transparent The overmask is exposed to ultraviolet light. This mask is the circuit diagram inside the chip that has been drawn in advance. The photoresist exposed to ultraviolet light will be dissolved and removed, and the ultraviolet light will pass through this mask and copy on the wafer. The rough circuit structure of the chip is formed.

Next, after applying photoresist again, performing photolithography, ion implantation, removing photoresist, electroplating, surface copper plating, polishing, cutting, and inspection, etc., a complete chip is Appeared in front of everyone.

Lin Haiyuan took two steps at a time and quickly retrieved a square chip.

"Chief Qin, this is a manufactured chip. Lin

Haiyuan sent the chip to Qin Xiao with a strong tone of voice.

Qin Xiao looked at the chip carefully and nodded:"Let's do the testing." Lin

Haiyuan nodded and put the chip into a new machine, a testing instrument specially used to test chip specifications.

In less than three minutes, the test results came out.

With less than an A4 test result, Lin Haiyuan held it in his hand. At that time, it was as heavy as a thousand pounds, making his hands tremble.

"Chief Engineer Qin, test results."

Lin Haiyuan did not dare to look at it, but handed the test results directly to Qin Xiao.

Under the nervous gazes of Lin Haiyuan and others, Qin Xiao took the test report and lowered his head to read it.

And when he saw that When it came out that the target was met, Qin Xiao couldn't help but breathe a sigh of relief, and raised the corners of his mouth slightly. Seeing the barely visible smile on the corner of Qin Xiao's mouth, how could Lin Haiyuan and others not know the result, but even so, they still looked nervous He asked:"Chief Master Qin, how was the result...?"

Qin Xiao took a deep breath and said two words that made several people unbelievable:"Meet the standard!"

Has the standard been met?

Is it really met?

In the laboratory, there was a moment of dead silence.

But this dead silence was soon broken by an incredible cry.

"ah!"

"Really successful?"

"Chief Master Qin, the transformation has really been successful, you are so awesome!"

"Half a month, only half a month, this is incredible!"

"If I weren't sober now, I'd probably feel like I'm dreaming"

"I thought... when Chief Engineer Qin proposed the transformation, I really thought that this transformation would take at least several years. After all, Dongshen has not even developed a 7nm lithography machine, and a 5nm lithography machine has not yet been developed. Engraving the machine will take at least three to five years, but……"

"But I really didn't expect that Chief Engineer Qin completed the transformation in only half a month, and the chips produced were up to standard. This is incredible!"

"I couldn't believe my eyes."

This is screaming!

Shock! (To read Baoshuang novels, go to Feilu Novel Network!)

Unbelievable!

Lin Haiyuan and others were extremely excited for a moment.

The entire laboratory suddenly entered a boiling state.

Shocking sounds , resounded.

Lin Haiyuan and the other seven looked overjoyed. Even though their actual participation in the process of transforming the lithography machine was not very high, they were very clear about the significance of creating an M-art lithography machine.[]

This means that the Dongshen Alliance could not even manufacture 7nm process lithography machines before, but now it can already manufacture 5nm process lithography machines.

It proves that the Eastern God Alliance has become one of the few forces on the Source Star that can produce 5nm lithography machines.

Perhaps, to some major lithography machine manufacturing forces, 5nm technology is nothing. After all, forces like Beihe are already able to manufacture 1nm lithography machines.

But for Dongshen, this was a huge breakthrough, an unprecedented success and feat.

The most important thing is that Qin Xiao only took half a month to accomplish something that the Eastern God Alliance had not been able to do for more than ten years, or even decades.

One can imagine how much this small chip shocked a few people.

Although Qin Xiao was also very happy, he was not as excited as Lin Haiyuan and others. He had experienced too many such things.

Whether it is building a third-generation aero engine, developing a fifth-generation fighter jet, or a controllable nuclear fusion device, they are all more accomplished scientific research projects than photolithography machines.

A 5nm lithography machine has not yet reached the level that makes him happy.

In fact, when he saw the surprised expressions on Lin Haiyuan and others' faces, he frowned tightly.

The lithography machine of the 5nm process can be implemented quickly, but it does not mean that the 1nm process can also be done so quickly.

Moreover, the premise is that the extreme violet lithography technology, which is strictly blocked by Beihe and other forces, needs to be developed first.

Thinking of this, the joyful moment of transforming the 5nm lithography machine was completely lost.

"Success once does not mean success every time. Next, mass-produce a thousand chips. After testing the success rate, write me a description."

"Although a 5nm process lithography machine has been successfully transformed, the most sophisticated one now is Beihe's EUVlnm process lithography machine. The process of this lithography machine still needs to continue to be transformed."

After Qin Xiao gave the instructions, he turned around and got into the small room again. When

Lin Haiyuan and others heard this, they looked at each other a little. After looking at each other, doubts appeared directly on their faces.

After that, After a while, someone said:"Chief Master Qin seems... not satisfied?"

"Seems a little dissatisfied"

"Before this, we didn’t even develop a 7nm process lithography machine. Now we have developed a 5nm process lithography machine. Shouldn’t we be very excited? This is an epoch-making moment!"

"Continue to transform the craft? What kind of photolithography machine does Master Qin want to transform so that he can think of it!"

"Maybe this is the difference between Master Qin and us!"

"Don't think so much. With 500 chips and a photolithography machine, it's not a small project. After the finished product comes out, you still have to test it and write a report. There's a lot to do. Let's finish what Chief Qin told us. That’s fine. As for the rest, we, the little guys, don’t think too much about it."

"Haiyuan is right, then let’s get started!"

After the few people finished speaking, they started to move.

Just when Lin Yuan and others started making chips at full capacity, two guards with guns and ammunition suddenly put their feet together at the door and saluted the old man in front of them:"Zhou. Bachelor."

The guard from the Eastern Academy of Sciences was quite familiar with Zhou Qichen. When he saw Zhou Qichen arriving, he immediately raised his hand and saluted him.

"Is Dean Qin here?"

"Yes, we heard Dean Qin's voice just now."

When Qin Xiao was mentioned, a look of fanaticism appeared in the eyes of the two guards.

"Okay, let me go in and take a look."

The two guards did not stop him, but continued to perform their guard duties seriously after Zhou Qichen entered the laboratory.

When he entered the laboratory, Zhou Qichen discovered that Qin Xiao did not seem to be in the laboratory, and only Lin Haiyuan and a few people were operating a machine there. A small photolithography machine, I don’t know what it was doing.

Zhou Qichen approached a few people and suddenly said:"What are you doing? Where is Chief Qin?"

A few people who were busy hearing the sound coming from behind them turned around and saw that Zhou Qichen was standing behind them, saying hello one after another.

Zhou Qichen pressed his hands and pointed at the lithography machine:"What are you doing?..."

Lin Haiyuan didn't think much and responded directly:"Chief Engineer Qin asked us to do another mass production chip test to see how this 5nm lithography machine is running."

Zhou Qichen originally just asked casually and didn't think much about it. He just came and subconsciously asked a few questions.

This time, he came here mainly to see Qin Xiao and ask if he had any other needs. How is he? Arrange people to prepare.

But before I can ask, my pupils shrink for a while.

5nm Yili lithography machine?

Isn’t the 7nm Yili lithography machine purchased?.
