Chapter 94 The Shock of the Researchers [Third]

"Then follow this arrangement first, and make adjustments if there is something inappropriate in the process."

As an old man in the industry, Hao Yaoping definitely hopes to see good talents appear among the younger generations. After all, they are the backbone of the future development of the industry.

So although I was a little worried about Xu Lei being responsible for the research and development of lasers, I saw the confidence that Xu Lei showed.

Finally agreed.

It would not be too late to add more staff after Xu Lei personally experienced the difficulties.

As the saying goes, if you can't cut a jade, you can't make a weapon, and experiencing a little setback can often make a person grow up faster.

Anyway, Hao Yaoping thought so.

And with Hao Yaoping speaking, other project developers naturally would not have any objections, and soon devoted themselves to their respective jobs.

Because many of these people have experienced the research of lithography machine-related technologies, and the jobs assigned by Xu Lei are in line with their own majors, so it didn't take long to get into the state completely.

There was none of the chaos at the beginning of the project.

As for Xu Lei, he is very satisfied with this.

At least it made him a lot easier.

After the others left, he also took the two assistants he arranged to the light source laboratory.

-

Ma Congming and Hu Xing are both in their early thirties this year. It can be said that apart from Xu Lei, they are basically the two youngest among the R&D personnel of this lithography machine project, and they are only ordinary scientific researchers.

It is completely incomparable with academicians like Hao Yaoping.

So much so that after seeing them being selected by Xu Lei to be responsible for the research and development of lasers, they felt a little guilty.

Although their majors are indeed related to this field, they also know how difficult it is to manufacture lasers that can emit ultraviolet light sources with shorter wavelengths. The three of them are actually responsible for such an important core component.

Even academicians don't have the confidence!
I'm afraid it's hard to make progress.

It would be embarrassing if the development speed of the laser cannot keep up with other components.

So out of this concern, after several people entered the light source laboratory and closed the door, they took the initiative to remind them a few words.

"Xu Gong."

"The lighting system consists of multiple subcomponents."

"It is more important to consider the wavelength power conversion rate and service life of the emitting light source."

"With the level of technology we have now, it is really difficult to develop a light source that can meet the needs of top-level lithography machines."

As Ma Congming took the lead in expressing his point of view, Hu Xing next to him quickly took over the conversation and echoed: "It is normal to want to prove one's strength, but I think it is better to be more prudent. What do you think about XCMG?"

Xu Lei is well aware of what these two people want to express in their words.

To sum up, it is believed that he is not enough to develop the light source required by top-level lithography machines, and the number of scientific researchers should be increased steadily.

Xu Lei asked the two of them to be his assistants because he valued that the other was the youngest among all the R&D personnel.

The way of working in the Chinese Academy of Sciences has not been deeply affected.

In this way, when faced with orders, they will only try their best to do so, instead of questioning the technical knowledge they have mastered, otherwise it will inevitably affect the progress of research and development.

After all, what Xu Lei wants to do is to strive to manufacture a top-level lithography machine that can produce 1-nanometer chips in a short period of time. He doesn't have to be a teacher to answer other people's questions while working.

So it is normal for Ma Congming and Hu Xing to feel strange about this.

To obtain an extreme ultraviolet light source with a shorter wavelength, the method to be adopted is to irradiate high-power carbon dioxide laser pulses on a tin droplet target with a very small diameter to excite high-power plasma as a light source for a lithography machine.

The entire light source system requires devices such as high-power lasers, focusing and position-controlled vacuum vessels, droplet generator collectors, and metering modules.

One of the most critical technologies is pre-pulse, and the generation of extremely small and stable tin droplets at high frequencies.

Coupled with the collector related to the service life of the light source device, the difficulty is really unimaginable.

But for Xu Lei who has mastered all the core technologies, it is not too difficult to manufacture a device that can meet these requirements.

Faced with this situation, it is obviously impossible to increase the number of scientific researchers.

However, in order for the two of them to cooperate with their work with peace of mind, Xu Lei finally said a few more words.

"I know what you are worried about, but since I dare to make this kind of personnel arrangement, there must be a reason."

"Believe me."

"It won't be long before you see a full-fledged EUV emission system."

The voice just fell.

Xu Lei turned around and walked towards the workbench, obviously not wanting to waste any more time on this issue.

Hearing these words, Ma Congming and Hu Xing first glanced at each other, and then went straight to the workbench like Xu Lei.

Because although they are worried that the research and development on the light source will not catch up with other people's progress, they don't want to be transferred from the research and development project. After all, Xu Lei is the person in charge of the project anyway, and has the right to adjust the increase or decrease of developers. .

Anyway, in their view, when Xu Lei's research on the light source system hits a bottleneck, he will definitely take the initiative to change.

……

Compared with dealing with the company's business before and concentrating on technical research, Xu Lei obviously felt that time seemed to pass faster.

More than ten days passed in a blink of an eye.

And in these days, Xu Lei, with the assistance of Ma Congming and Hu Xing, finally completed the assembly of the laser.

Although this is just one of the devices in the entire light source system, it represents a different meaning.

It marks that they have successfully taken the first step.

However, in order to apply the laser to the light source system, it is necessary to test its power wavelength and life to ensure that it can meet the needs of top lithography machines.

"XCMG, the laser is ready for testing."

This morning.

In the light source laboratory.

After Ma Congming finished installing and debugging the laser, he immediately opened his mouth to report to Xu Lei.

A little excitement can be heard in the speech.

They also contributed somewhat to the main assembly of this laser. Although they don't believe that the test data can reach the overseas level, as a scientific researcher, it is always difficult to control the excitement in my heart at this time.

of course.

Compared to the two of them, Xu Lei was much calmer.

Seeing that Ma Congming was ready, he immediately issued an order to start the test.

"let's start."

After finishing speaking, he still did not forget to tell Hu Xing: "Hu Xing, pay attention to all data analysis."

"Don't worry, XCMG." Hearing the sound, Hu Xing promised quickly, and stared at the computer screen intently.

Almost at the moment when Xu Lei's voice sounded, Ma Congming immediately activated the laser to emit laser light, and accurately hit the falling tin droplet to stimulate high-power plasma.

At the same time, various data will be directly transmitted to the computer through the sensor for analysis and calculation.

Since the test also includes the life of the laser, the time required in the middle will certainly not be too short. It was not until Hu Xing's surprised voice sounded in the laboratory that the two of them came back to their senses and immediately cast their inquiring gazes.

"How's the data?"

"The laser developed by XCMG not only has a power far exceeding the standard of overseas high-end lithography machines, but also has a very short wavelength of the light source. You can see the detailed data for yourself."

Hu Xing heard Ma Congming's words, and after speaking these two sentences with a slightly trembling voice, he directly handed the printed data file to the other party.

Ma Congming naturally didn't dare to hesitate when he took the document, and quickly lowered his gaze to examine it carefully.

After seeing clearly the various test results marked above, he could no longer suppress the excitement and shock in his heart, and his pupils were no less than a big earthquake.

It wasn't until this time that he finally understood why Xu Lei only hired the two of them as assistants when facing such an important light source system.

Especially thinking of the doubts I had about Xu Lei before, I feel even more ashamed.

But at the same time, I firmly believe that this time they will definitely be able to develop a top-level domestic lithography machine.

After a pause of about ten seconds, he walked towards Xu Lei, handed over the data file and said in a deep voice: "Xugong, I really didn't expect you to have such deep research in this field. , please forgive me for questioning you earlier."

"This laser can achieve this effect, so it should be able to be used in the light source system?" Seeing this scene, Hu Xing immediately asked with anticipation.

But after Xu Lei took a look at the data file from Ma Congming, he shook his head and said: "Not yet, this is only the first generation of laser we manufactured, and it still needs optimization and debugging in many aspects before it can be put into use. .”

According to the data of this test, although it exceeds the laser used by overseas high-end lithography machines, it can produce chips with a maximum size of 5 nanometers.

There is still a distance from the physical limit required by Xu Lei, and multiple optimization and debugging are needed.

In addition, what Ma Congming wants to say, he can basically guess with his toes, so there is no need to waste time here.

"Okay, our next task is very heavy, so feel free if you have anything to say."

"It's XCMG."

Both of them understood the meaning of Xu Lei's words, and after replying in unison, they immediately returned to work.

And the enthusiasm at this moment has definitely doubled compared to the previous few days.

After all, after they really understood Xu Lei's level, they knew how much being his assistant would improve them.

It is worth mentioning that the achievements made by Xu Lei on the laser also quickly spread to the ears of every project research and development personnel, which shocked almost everyone.

Even Hao Yaoping had to praise the sentence genius from the bottom of his heart.

So much so that in the days to come, as long as everyone encountered problems in technology research and development, they would run over to ask Xu Lei for advice.

It makes Xu Lei seem to be only in charge of the light source of the lithography machine for the time being, but in fact he is involved in every component.

Invisibly, it has greatly improved the research and development progress of domestic top-level lithography machines.

However, when the Chinese Academy of Sciences was in full swing to conquer the top lithography machine technology, Brady in Washington state hurried to where Mike was.
