"It's not easy for us to succeed!"

In the laboratory.

As the photoresist was prepared, the room suddenly shouted excitedly.

However, when Xu Lei faced his assistant's performance, he did not show any joy. Instead, he said to him in a deep voice: "It is still a bit early to say that it is successful now. It needs to be applied to the wafer for actual testing before it can be confirmed."

In fact, he was quite sure about this experiment, and the photoresist he prepared should meet his requirements.

It was just out of scientific rigor that he was more calm.

Hearing sound.

The assistant quickly calmed down.

After I was controlled, I apologized a little embarrassedly: "Sorry XCMG, I'm so happy to forget this."

"It doesn't matter."

For Xu Lei, this is just a small episode, so he naturally won’t take it to heart. After spitting out these three words, he immediately said: “Director Yang and Mr. Hao are still waiting for our news. Let’s go over the prepared photoresist tape quickly.”

“This will be the best New Year’s gift.”

Just finished speaking.

The body had already stepped out of the laboratory.

"It's XCMG."

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

Although they were all young and middle-aged men, their palms were trembling slightly uncontrollably at this time.

After all, this prepared photoresist also has their efforts. It is about to be tested. It has become an indispensable and important part of the top domestic lithography machines. The heart beats quickly as if it is turned on with full power.

As normal.

Because today happens to be New Year's Eve.

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

But after learning that the photoresist will be prepared today, no one of the project research members, including Yang Senping and Hao Yaoping, chose to go home for the festival.

At night, they all stayed in the hospital and waited for Xu Lei's research results.

It is absolutely extraordinary for them to see high-end chips produced by their own lithography machines.

Not long.

When Xu Lei came to the area where the assembled top lithography machine was located, a group of people quickly surrounded him, and his face showed a look of expectation.

"How is it, did it succeed?"

"It should be no problem, but the specific effect still needs to be tested." Looking at Yang Senping's familiar face, which almost occupied most of his vision, Xu Lei did not deliberately keep it insincerely and directly explained the actual situation truthfully.

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

"good."

"OK."

“It’s so good.”

Getting the exact answer from Xu Lei's mouth, Yang Senping's hanging heart finally landed. After saying three consecutive words, he immediately issued a test order.

"Let's start testing, let's have a special New Year's Eve tonight."

"I didn't expect that my old bone was so passionate, it was really not easy." In this atmosphere, Hao Yaoping couldn't help but sigh a few words.

The components of this top-level lithography machine have been assembled long ago, and they have been debugged many times when Xu Lei made the photoresist.

There is no problem with booting up and using it.

When the lights were on the outside and the family was having fun, the first top domestic lithography machine finally roared in its own way, sending the most precious blessings to this New Year.

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

As for wafers coated with photoresist, they have long been placed on the exposure platform, and the circuit is etched out on it with the help of light sensitivity.

Although this process does not take a long time, because it requires various data testing and analysis of the produced chips to ensure that it is a qualified product, you still need to wait patiently to get the final result.

It's no exaggeration to say.

Among everyone present, except Xu Lei, who was very nervous at this moment.

I am willing to believe that this project will be successful, but I am also afraid that something will happen if I happen.

——

that's all.

Everyone suffered a lot until the New Year bell was about to ring at the Spring Festival night, and then they saw a tester walking in with excitement on his face, holding a data analysis document in his hand.

"Director Yang, the various test data of the chip have come out."

"Take it over 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. Gu Zhi

Reached up and took the document and checked it carefully.

After about half a minute passed, he realized that Yang Senping could no longer hide his excitement, so he immediately announced to everyone loudly.

“We succeeded.”

"From today we will have a mature 3nm high-end chip production process."

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

This result can be said to be completely within Xu Lei's expectations. He was not surprised by it, so he took the document and browsed it a few times, and then passed it to Hao Yaoping and other members of the research group of other projects.

Let them share this joy too.

"It's really unbelievable. We have conquered the lithography machine technology that has not been achieved for many years. Now it has not only achieved but also directly surpassed the overseas technology level."

"Who said no, half a year ago would have thought that the Spring Festival would be able to see such a big surprise."

"It all depends on XCMG. It makes sense that geniuses are called geniuses."

As the feelings of Hao Yaoping and others came to his ears, Yang Senping took over the conversation and added: "Next, we will mass-produce this top domestic lithography machine so that it can have the ability to undertake production orders as soon as possible. By that time, our chip design company will not need to look for overseas wafer manufacturers to manufacture."

Just as everyone was immersed in this joy, Xu Lei suddenly asked: "Director Yang, has the special metal material bismuth I need been shipped here?"

“It was already here last month.”

When Yang Senping heard Xu Lei mention this, he answered in a deep voice and seemed to have thought of something, and asked quickly: "Can you really reach the physical limit of silicon-based chips using this metal and produce a 1-nanometer chip?"

"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 take advantage of the next big news. If our process reaches the 1-nanometer level, even if overseas wants to catch up, they are afraid they won't have that ability."

If everyone was excited about the achievements made by domestic lithography machines just now, then after hearing Xu Lei’s words, there was only shock left.

I couldn't help but take a breath.

In fact, for the members of the project research team, it is unimaginable to be able to develop a top-level lithography machine that produces 3-nanometer chips. As for the physical limit 1-nanometer chips, they have never 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, he no longer knew how to describe his whole mood.

However, in the end, Yang Senping temporarily stopped Xu Lei's actions. After all, it was already the New Year, and it was time to relax and relieve physical stress. It was not enough to always be on work.

So when Yang Senping's face was occupied by a smile again, he immediately said to Xu Lei: "I am already embarrassed to let everyone gather here on New Year's Eve today. How could I let you devote yourself to your work?"

"I have already booked a celebration banquet. I will talk about other things after the Spring Festival first."

"Besides, it's not that I have to do it in the past few days."

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

Although he also wanted to solve the chip problem and return to the company as soon as possible, the lithography machine has been successfully manufactured, and the special metal bismuth has been in place. It doesn’t take extra time to produce a 1-nanometer chip, and there is no need to worry about these few days.

Make sure the next arrangements.

Soon, a group of members of the project research team took a special car to the hotel Yang Senping booked in advance. It was obvious that Yang Senping had long believed 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 for China, because just as everyone greets 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 situations in the research and development of top domestic lithography machines and the 3-nanometer specification chip produced.

Officially announce its position in the semiconductor market.

Because of the previous fermentation of various news on the Internet, everyone believes that the Chinese Academy of Sciences cannot develop high-end lithography machines. Although they are disappointed with this, they cannot change anything.

But compared to the passion at the beginning, I have gradually lost interest 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, until they clicked in and watched the content inside, and their mouths were filled with shock.
