My science and technology museum

"We finally succeeded. It was not easy!"

In the laboratory.

As the photoresist was prepared, the room suddenly erupted with excited shouts.

But when Xu Lei faced his assistant's performance, he did not show any joy on his face. Instead, he said to him in a deep voice: "It's still too early to say it's successful. It needs to be applied to the wafer for actual testing." Sure."

In fact, he was relatively confident about this experiment, and the prepared photoresist should be able to meet his requirements.

It was only out of scientific rigor that he acted calmly.

Hear the sound.

The assistant quickly calmed down.

After controlling his emotions, he apologized a little awkwardly: "I'm sorry Xugong, I was so happy that I forgot about this."

"It doesn't matter."

For Xu Lei, this was just a minor incident, so naturally he didn't take it to heart. After spitting out these three words, he immediately said: "Dean Yang and Mr. Hao are still waiting for our news. Let’s hurry over to the prepared photoresist tape.”

"This would be the best New Year's gift."

The words just fell.

The body has already stepped out of the laboratory.

"It's XCMG."

The remaining assistants naturally did not dare to hesitate in the face of this explanation. They nodded quickly and began to pack up the photoresist on the workbench.

Even though they were all young men, their palms were trembling uncontrollably at this time.

After all, they have worked hard to prepare this photoresist. It is about to be tested and it will become an indispensable part of the top domestic photolithography machine. The heart is beating rapidly as if it is at full power.

As per normal conditions.

Because today happens to be New Year's Eve.

Even scientific researchers will return home to spend time with their families and enjoy this annual traditional festival.

But after learning that the photoresist would be prepared today, none of the many project research members, including Yang Senping and Hao Yaoping, chose to go home for the holidays.

They all stayed in the hospital late at night waiting for Xu Lei's research results.

Being able to see high-end chips produced by their own lithography machines with their own eyes is absolutely extraordinary for them.

Not long after.

When Xu Lei arrived at the area where the assembled top-level photolithography machine was, he immediately saw a group of people quickly surrounding him, with looks of anticipation on their faces.

"How's it going? Was it successful?"

"There should be no problem, but the specific effect still needs actual testing." Looking at Yang Senping's familiar face that almost occupied most of his field of vision, Xu Lei did not deliberately show off, and directly and truthfully briefly explained the actual situation.

The assistant who came behind him with the photoresist immediately echoed: "Dean, the prepared photoresist is here."

"good."

"OK."

"It's really great."

After getting the exact answer from Xu Lei, Yang Senping's hanging heart finally fell to the ground. After saying "good" three times in a row, he immediately issued the order for the test.

"Let's start testing. Let's all have a special New Year's Eve together tonight."

"I didn't expect that my old bones would still be so passionate. It's really not easy." In this atmosphere, Hao Yaoping couldn't help but sigh.

The components of this top-level photolithography machine have already been assembled, and they were debugged many times while Xu Lei was preparing the photoresist.

There are no problems when starting up and using it.

And when the lights were decorated outside and families were enjoying themselves, the first top-notch domestic lithography machine finally roared in its own way, sending the most precious blessings for this New Year.

As the laser emits laser light and hits the dripping tin liquid, a high-power plasma is excited, and the radiation emitted by the plasma in all directions is captured by the collector, concentrated and finally transferred to the lithography system to expose the wafer.

As for the wafer coated with photoresist, it has already been placed on the exposure table, and circuits are etched on it with the help of photosensitivity.

Although this process does not take a long time, because the produced chips need to be tested and analyzed to ensure that they are qualified products, you still have to wait patiently to get the final results.

Not exaggerating.

Of all the people present, except Xu Lei, he was feeling quite uneasy at the moment.

I am willing to believe that this project will be a complete success, but I am also afraid that something will go wrong in the end.

——

that's all.

Everyone was so exhausted that when the New Year's bell was about to ring in the evening of the Spring Festival, a tester walked in with excitement on his face and a data analysis document in his hand.

"Dean Yang, the test data of the chip are out."

"Bring it here quickly."

Finally, at this time, Yang Senping didn't care about his image, and took the initiative to walk towards the other party before he finished speaking.

He reached out and took the document and looked at it carefully.

About half a minute later, Yang Senping could no longer hide his excitement and immediately announced loudly to everyone.

"We succeeded."

"Starting from today, we will have a mature 3-nanometer high-end chip production process."

And while saying these words, he handed the document to Xu Lei.

It can be said that this result was completely within Xu Lei's expectation. He was not surprised by it, so he took the document and only glanced at it briefly before passing it to Hao Yaoping and other members of the project research team.

Let them share in this joy.

"It's really unbelievable. We have conquered the photolithography machine technology that has not seen results for many years, and now it has not only been realized but also directly surpassed the overseas process level."

"Who says it's not the case? Who would have thought half a year ago that we would see such a big surprise during the Spring Festival."

"This is all thanks to XCMG. The reason why geniuses are called geniuses is indeed very reasonable."

As the emotions of Hao Yaoping and others reached his ears, Yang Senping took up the conversation and added: "Next, we will mass-produce this top-level domestic photolithography machine so that it can have the ability to take production orders as soon as possible. By that time, we will chip design companies will no longer need to find overseas foundries."

Just as everyone was immersed in this joy, they heard Xu Lei suddenly ask: "Dean Yang, has the special metal material bismuth I need been shipped?"

"It arrived last month."

Yang Senping heard Xu Lei mention this, and after answering in a deep voice, he seemed to have thought of something, and hurriedly asked: "Is it really possible to use this kind of metal to reach the physical limit of silicon-based chips and produce 1-nanometer chips?"

"That's right."

"Although the top 3-nanometer lithography machine is enough to shock all walks of life overseas, I don't mind taking advantage of this momentum to make the next big push. If our process reaches the 1-nanometer level, even if overseas countries want to catch up, they may not have the ability."

If everyone was excited about the achievements of domestic lithography machines just now, then after listening to Xu Lei's words, they were only shocked.

Suddenly he couldn't help but take a breath of cold air.

In fact, for members of the project research team, it is unimaginable to develop a top-level photolithography machine for producing 3-nanometer chips. As for the physical limit of 1-nanometer chips, they have not even considered it.

Anyway, 3 nanometers alone is enough to lead overseas chip manufacturing technology.

So after learning that Xu Lei was really sure to produce a 1-nanometer chip, I didn't know how to describe my mood.

But in the end, Yang Senping temporarily stopped Xu Lei's move. After all, it was the New Year, and it was time to relax and relieve physical stress. It was not good to focus on work all the time.

So when Yang Senping's face was once again occupied by a smile, he immediately said to Xu Lei: "I, the dean, am already very embarrassed to have everyone gather here on New Year's Eve. How can I still allow you to devote yourself to work?" .”

"I have already made a reservation for the celebration banquet. I will wait until after the Spring Festival to finish the other matters."

"Besides, it doesn't have to happen in the next few days."

Speaking of which, Xu Lei will definitely not insist on anything.

Although he also wants to solve the chip issue as soon as possible and return to the company, now that the photolithography machine has been successfully manufactured, and the special metal bismuth is also in place, it does not take much extra time to produce a 1-nanometer chip. Pay attention to these days.

Decide on the next arrangements.

Soon, members of the project research team took a special car to the hotel that Yang Senping had booked in advance. Apparently Yang Senping had long thought that Xu Lei could prepare a photoresist that could meet the requirements.

…

Saturday, January 25, 2020.

Spring Festival.

Today is definitely a day worth remembering in China, because just when everyone is paying New Year greetings to their elders everywhere according to tradition, the official account of the Chinese Academy of Sciences released a special video without warning.

The video introduces some of the research and development of top domestic lithography machines and the 3-nanometer chips produced.

Officially announce its position in the semiconductor market.

Because of the previous fermentation of various news on the Internet, everyone believed that it was impossible for the Chinese Academy of Sciences to develop a high-end lithography machine. Although they were disappointed by this, it could not change anything.

But compared to the initial enthusiasm, I have gradually lost interest now, and I am too lazy to pay attention to this matter anymore.

So after discovering this video, many people didn't react for a while. After clicking in and reading the content, their mouths opened wide in shock.

I never expected that the Chinese Academy of Sciences would not only successfully develop a photolithography machine, but its process would also greatly surpass the technology owned by overseas companies.

Overtaking in corners was completely achieved.

Unexpected and explosive news like this spreads on the Internet at a speed that can hardly be described as fast. It didn't take long for the entire Internet to have a heated discussion on the same topic.

"Damn it, am I really wrong?"

"Please forgive me for my previous judgment. I didn't expect that a domestic lithography machine would actually be developed."

"It seems that overseas are still trying to produce 5-nanometer chips. We will go directly to 3-nanometer chips. This is definitely the most exciting news we have heard this year."

"Who swore that it couldn't be developed two days ago? Does it hurt from being hit in the face now?"

"I'm afraid we have already made a major breakthrough in the research of top-level lithography machines, but we have just done a better job of keeping it confidential."

"I want to know how overseas companies behave after learning the news."

"Just waiting for the market to open after the Spring Festival, my fund will definitely rise like a chicken."

The remaining two chapters will be updated together in the afternoon. Thanks to the honest Dunzi for the 200-point reward!
