Pulse detonation engine announced for entry into the Air Force

Chapter 452: The 1nm lithography machine has been tinkered with, so why does Chief Qin still look dissatisfied?

What is the key point of extreme violet light?

After a month of research, Qin Xiao finally had his own understanding of ultraviolet light.

Among them, the most difficult thing is the excitation of EUVL light source.

Therefore, extreme ultraviolet lithography technology, also known as EUV lithography, is a lithography technology currently used by the most advanced and cutting-edge lithography machines in the world.

To achieve extreme violet lithography technology, the most important thing is to excite it with a light source that does not produce radiation.

After this period of research, Qin Xiao discovered that neutral atoms and condensed matter do not produce EUV radiation.

But if you want to make a material glow, the first thing you need to do is ionization, because extreme ultraviolet light is only produced by electrons bound by multiple positively charged ions.

For example, an electron from a carbon ion requires +3 eV, such electrons are more tightly bound than typical valence electrons.

Multivalent positive ions can only exist in high-temperature and high-density plasmas and will strongly absorb EUV themselves.

This is the key to realizing ultraviolet lithography technology.

Moreover, EUV lithography is very different from deep ultraviolet lithography, which is widely used today and belongs to the forefront of science and technology.

EUV absorbs EUV in all materials because it is close to soft X-rays with a wavelength of 13.5nm.

Therefore, EUV engraving must be performed in a vacuum. Non-vacuum conditions may result in EUV loss.

These are what Qin Xiao has gained during this period.

Perhaps, relatively speaking, there are still many shortcomings, but it is enough to carry out the first extreme ultraviolet lithography.

Practical application is the only criterion for testing truth. Likewise, it is also the key to discovering problems.

In the laboratory, Lin Haiyuan and others are nervously preparing various instruments and equipment.

Slightly different from the previous experiments, extreme violet lithography technology has extremely high requirements. Even Qin Xiao is not confident whether it can succeed in the first time. This means that the data collection work during the experiment becomes crucial. important.

The problems with extreme ultraviolet lithography technology cannot be seen with the naked eye. It requires using various instruments and equipment to capture data, and intuitively understand some information through the data. From this information, problems can be found and solved. After continuous attempts, repairs, and improvements, it is finally possible to develop a real EUV engraving machine.

Lin Haiyuan and others, who knew the importance of this experiment, were very cautious, fearing that they would make a mistake and the experiment would not be successful, or that they would not be able to capture key data.

After more than two hours of various debugging, Lin Haiyuan and others found that there were no problems. They breathed a sigh of relief and walked directly to the office not far away.

Lin Haiyuan raised his hand and knocked on the door:"General Master Qin, all the equipment has been debugged."

At this moment, Qin Xiao was still checking the previous design book. When he found no problems, he put down the design book and faced Lin Haiyuan. The others nodded.

Then, he got up and walked towards the laboratory.

In the laboratory, in addition to the necessary instruments and equipment, there is also the previous large 7nm lithography machine.

At this moment, this 7nm Yili lithography machine has been transformed into an EUV lithography machine. As for whether it can be successful, everything depends on this experiment.

In addition to these, there is a large screen located on the side.

On the big screen, various data are listed.

Qin Xiao stood directly in front of the big screen.

Seeing Qin Xiao standing in front of the big screen, Lin Haiyuan and others all stopped breathing and looked nervously.

Is it finally starting?

Several people never thought that this day would come so early or so quickly.

According to their understanding of scientific research, especially such a major scientific research project, no results can be produced in less than three to five years.

Not to mention scientific research results, just a little progress may take several years to achieve.

Moreover, they all think so. Even though Qin Xiao successfully transformed a 5nm art lithography machine before, they still don't think Qin Xiao can complete the research and development of a 1nm art lithography machine in a short time.

From 5nm process to 1nm process, the gap may not seem big, but at the technological level, it will be infinitely magnified.

Just like the gap between a speck of dust and a basketball, this gap cannot be shortened in a short time.

Even if nothing unexpected happens, it will be impossible for the Eastern God Alliance to realize 1nm technology within ten years.

Although this statement is somewhat absolute, I have to admit that this is the truth.

It is precisely because of this that they understand how incredible it is to complete the research on extreme violet lithography technology in one month.

Even though no experiments have been conducted yet to prove whether the research and development has actually been completed, several people were still shocked.

One month, given to others, may not be possible in ten years.

The difference between this can be imagined.

Just when several people looked nervous, Qin Xiao raised his head with a serious look on his face:"Put in the wafer, turn on the power, turn on the lithography machine, and start manufacturing the first 1nm chip."

"yes!"

Lin Haiyuan and others came to their senses and responded quickly.

The others approached the equipment for collecting data.

Lin Haiyuan walked directly to the lithography machine and pressed the switch representing the power supply of the lithography machine.

Immediately afterwards, the light The sound of the engraving machine starting up was heard.

Under the nervous gaze of everyone, after a while, a chip was successfully manufactured.

"Chief Qin, the chip has been manufactured. Lin Haiyuan reported quickly.

Qin Xiao nodded:"Carry out chip testing and print out all the data.""

"yes."

Lin Haiyuan stood up straight, carefully held the chip and walked to the chip test instrument, and started the test work.

The test of a chip requires a lot of test data. After about ten minutes, several automatic pictures appeared. The printed test report.

Lin Haiyuan took the data report, glanced at it, and his pupils shrank for a while. The next moment, he shouted with surprise:"General Master Qin, it was successful. It was produced by this photolithography machine." The chip has fully reached today's highest standards, and some of the data have even exceeded the EUV engraving machine announced by Beihe before."

"The only question now is whether this lithography machine can withstand large-volume chip manufacturing, and the speed of chip manufacturing. These two are also important criteria for measuring the cutting-edge technology of a lithography machine."

Lin Haiyuan's excited voice sounded in the laboratory.

Others, at this moment, also had joy on their faces.

They naturally knew what this meant, which meant that even if these two items did not meet the standards, 1nm Yiguang The research and development of the engraving machine is still successful, but the flaws are relatively large. (To read Baoshuang novels, go to Feilu Novel Network!)

And once these two meet the standards, or even exceed the standards, that means, The 1nm lithography machine independently developed by Qin Xiao has surpassed Beihe.

In terms of lithography machine technology, it has surpassed Beihe, which even the Star Alliance cannot imagine.

Now, Qin Xiao has done it.

And , it only took less than two months from the beginning to the present.

At this moment, there is only one word in their minds to describe their mood now.[]

That is, unimaginable.

Really unimaginable.

Moreover, the most critical thing is not the completion of the research and development of the 1nm lithography machine, but the completion of the 1nm lithography machine, which has a huge impact on the Dongshen Alliance.

With this experience, in the future, the Dongshen Alliance will definitely be at the forefront of the world in lithography machine technology.

Lithography machines will no longer be blocked by other forces, and there is no need to worry. Without the advanced lithography machines provided by forces such as Beihe, some industries in Dongshen will not be able to develop at a deeper level.

All the worries before will disappear completely because of the appearance of this photolithography machine.

"You do the testing, I just want the final data report."

Qin Xiao nodded and said thoughtfully:"In addition, you have also signed a confidentiality agreement regarding the EUV secret. Before it is officially announced, it cannot be spread in any way or situation. Once there is a problem, I miss you the consequences. It's all clear"

"This is not a threat to you, but there are some things that you, as assistants, need to know the severity of."

"Also, the information and confidentiality agreements you have access to are basically lifelong. In other words, even if you die, everything you know in this laboratory will rot in your stomach."

"I didn’t remind you before because there were no results yet. Now that I have succeeded, I have to say something."

"Chief Master Qin, you don’t need to say more, we all know it. When Qin

Xiao said this, Lin Haiyuan and others responded one after another:"From the time we signed the confidentiality agreement, we have been ready to take this project into the coffin. Don't worry, just We will never mention the engraving matter outside."

"That'll do. Qin

Xiao nodded slightly, then thought for a moment and said,"As long as you know it, I'll leave the testing to you.""

"good."

Several people, when Qin Xiao walked into the small room, were all surprised.

Even 1nm Art's lithography machine has been tinkered with, why is Chief Qin still looking unhappy?

Several people, a little confused at this moment.

On the other side, the photolithography machine's dosage test will not end in a while. Qin Xiao did not stay here any longer, but got into the small room again.

"Although it was done, everything else was done with the help of existing photolithography machines.……"

Qin Xiao knocked on the table and frowned slightly.

However, it soon relaxed again.

What limits the development of Dongshen's lithography machines has never been other places. Now, the most critical extreme violet lithography technology has been solved by him. With Dongshen's current level, he can also create exactly the same products, even As long as you spend time, you can do better than Beihe.

He just solves the hardest part.

As for the rest, let others handle it.

Time passes bit by bit

…… the other side.

Lao Cui, who is studying new materials, is sitting down in Zhou Qichen's office.

Zhou Qichen stared at the other party and asked:"Old Cui, how is your new material going? Is there any progress?"

Old Cui smiled bitterly:"It has only been three months since the project was established, what progress can be made? , It has just begun,? Lao Zhou, that is, if you ask, if others ask this, I will have to scold you, who can make great progress in scientific research tasks in two or three months?"

"New materials are not a small scientific research project, it is not that easy. Lao

Cui sighed with emotion, then raised his head and asked,"By the way, how is Principal Qin's project going?"".
