Chapter 98 World-leading chip manufacturing process

"We finally succeeded, it's really not easy!"

inside the laboratory.

As the photoresist was prepared, the room suddenly burst into shouts of excitement.

However, Xu Lei didn't show any joy on his assistant's performance. Instead, he said in a deep voice: "It's still too early to say success, and we need to apply it on the wafer for actual testing before we can do it." Sure."

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

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

heard.

The assistant quickly calmed down.

After controlling his emotions, he apologized in embarrassment: "I'm sorry Xugong, I was too happy to forget this."

"It's ok."

For Xu Lei, this was just a trivial episode, so he naturally didn't take it to heart, and after spit out these three words, he immediately said: "President Yang and Mr. Let’s hurry over to the prepared photoresist tape.”

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

The voice just fell.

The body has already stepped out of the laboratory.

"It's XCMG."

The rest of the assistants naturally didn't dare to hesitate in the face of this statement, nodded quickly in response, and began to pack up the photoresist on the workbench.

Even though they were all young and middle-aged lads, their palms trembled uncontrollably at this moment.

After all, the prepared photoresist also has their hard work. Seeing that it is about to be tested and becomes an indispensable and important part of the domestic top-level photolithography machine, the heart beats as if it is at 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 preparation of the photoresist would be completed today, none of the many project research members, including Yang Senping and Hao Yaoping, chose to go home for the holiday.

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

It is absolutely unusual for them to see high-end chips being produced by their own lithography machine.

Soon.

When Xu Lei came to the area where the assembled top-level lithography machine was located, he immediately saw a group of people quickly gathered around, all with expectant expressions on their faces.

"How is it, did it work?"

"There should be no problem, but the actual effect needs to be tested." Staring at Yang Senping's familiar face that almost occupied most of his field of vision, Xu Lei didn't deliberately try to be tricky, and directly explained the actual situation truthfully and briefly.

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

"it is good."

"Okay."

"That's great."

After getting the exact answer from Xu Lei, Yang Senping's hanging heart finally fell to the ground, and after saying yes three times in a row, he immediately gave the test order.

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

"I didn't expect that my old bones were still so passionate. It was really not easy." Being in such an atmosphere, Hao Yaoping couldn't help feeling a few words.

The components of this top-level lithography machine have already been assembled, and several times of debugging were carried out when Xu Lei prepared the photoresist.

At this time, there is no problem in starting up and using it.

And when the lights and festoons were decorated outside and the family was having fun, the first top-level domestic lithography machine finally roared in its own way, sending the most precious blessings for this new year.

Accompanied by the laser emitting laser light and hitting the dripping tin liquid to excite high-power plasma, the radiation emitted by the plasma in all directions is captured by the collector, concentrated and finally delivered to the photolithography system to expose the wafer.

As for the wafer coated with photoresist, it has already been placed on the exposure table, and the circuit is etched on it with the help of light sensitivity.

Although this process does not take a long time, it is necessary to wait patiently to get the final result because it is necessary to test and analyze various data of the produced chip to ensure that it is a qualified product.

No exaggeration to say.

Everyone present, except Xu Lei, was feeling quite nervous at the moment.

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

-

that's it.

Everyone was suffering until the New Year's bell was about to ring on the Spring Festival evening, and only then did a tester walk in with a face full of excitement, holding a data analysis document in his hand.

"Dean Yang, the test data of the chip has come out."

"Bring it here."

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

He reached out to take the file and examined it carefully.

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

"We made it."

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

And when he said these words, he handed the document to Xu Lei.

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

Let them share in the joy too.

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

"Whoever said no, half a year ago, who would have thought that there would be such a big surprise during the Spring Festival."

"It all depends on XCMG. The reason why a genius is called a genius is indeed very reasonable."

As Hao Yaoping's feelings spread to his ears, Yang Senping took over the conversation and added: "Next, we will mass-produce this top-level domestic lithography machine so that it will be able to undertake production orders as soon as possible. At that time, we will Chip design companies do not need to look for overseas foundries."

And just when everyone was immersed in this joy, Xu Lei suddenly asked: "President Yang, has the special metal material bismuth I need been delivered?"

"It was here last month."

When Yang Senping heard Xu Lei mention this, Shen Sheng seemed to think of something after answering, and hurriedly asked: "Could it be possible to use this metal to reach the physical limit of silicon-based chips and produce 1-nanometer chips?"

"Yes."

"Although the 3-nanometer top-level lithography machine is enough to shock the overseas community, I don't mind taking advantage of this momentum to make the next big news. If our technology 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 the domestic lithography machine just now, then after listening to Xu Lei's words, there is only shock left.

Suddenly he couldn't help taking 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 can produce 3-nanometer chips. As for the physical limit of 1-nanometer chips, they have never considered it at all.

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

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

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

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

"I've already booked the celebration banquet, and we'll talk about other things after the Chinese New Year after eating this meal."

"Besides, it doesn't have to be done in the past few days."

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

Although he also wants to return to the company to solve the chip problem as soon as possible, but now that the lithography machine has been successfully manufactured, and the special metal bismuth is also in place, it does not take much time to produce a chip with a size of 1 nanometer. Care about these days.

Make sure of the next arrangements.

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

……

Saturday, November 2020, 1.

Spring Festival.

Today is definitely a day worth remembering for the country, because just when everyone pays New Year greetings to the elders in accordance with the 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 domestic top lithography machines, as well as the 3nm chips produced.

Officially declared its position in the semiconductor market.

Because of the previous ferment of various news on the Internet, everyone thought that it was impossible for the Chinese Academy of Sciences to develop a high-end lithography machine. Although they were disappointed, they couldn't change anything.

It's just that compared to the passion at the beginning, I have gradually lost interest now, and I don't bother to pay attention to this matter anymore.

So after discovering this video, many people didn't react for a while, until they clicked in to read the content, and instantly opened their mouths and were full of shock.

I never expected that the Chinese Academy of Sciences not only successfully developed a lithography machine, but even the technology greatly surpassed the technology owned by overseas companies.

It is completely proper to realize the corner overtaking.

The speed at which such unexpected and explosive news spread on the Internet could hardly be described as fast, and it didn't take long for the entire Internet to discuss the same topic intensely.

"Damn it, isn't that what I read wrong?"

"Please forgive me for my rash conclusions. I didn't expect the domestic lithography machine to be developed."

"Overseas seems to be trying to produce 5-nanometer chips now, and we are now going directly to 3-nanometer. This is definitely the most gratifying news I heard this year."

"Who swore that it couldn't be developed two days ago, may I ask if your face hurts now?"

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

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

"Wait for the opening of the market after the Spring Festival, my fund will definitely go up in popularity this wave."
