Homecoming of Rebirth

"Second, I have canceled all subscriptions. Why do you need so much water? Are you sick?"

"Third, what is wet engraving? You don't understand technology, so don't come up with ideas!"

Qi Lei, "Hang up!"

Now, he can basically confirm that EUV LLC is doing wet etching.

Before the wet etching method, that is, the immersion lithography machine came out, several major lithography machine manufacturers, including Nikon, ASML, etc., were dry etching.

The so-called photolithography is the process of hitting light on the mask and then projecting it onto the wafer, so that the optical glue on the wafer reacts and travels the circuit.

In the era of dry etching, photolithography from the light source to the mask to the wafer is completed in a gaseous medium, and the limit is 193 nanometers.

Wet etching, as the name suggests, is to move the photolithography process carried out in the gas medium to water.

What's going on, anyway, Qi Lei doesn't understand, he knows that wet engraving has advantages over dry engraving, and can break through the limit of 193 nanometers without changing other components and precision of the lithography machine.

This is also a few words that Qi Lei got in the reports of later generations.

And I also know that this process from dry etching to wet etching was proposed by a technician from TSMC.

He also came up with an idea by accident, and said casually, "As long as water is poured into the lithography machine, the chip manufacturing process can be greatly improved."

In the end, this technological revolution was achieved.

Yes, that's right, it's that simple!

Although the process from the original lithography technology to wet etching is definitely much more complicated and difficult than this sentence.

However, the principle is so simple, it is a casual idea.

The reason why EUV LLC is so confidential is also here, it's too simple!

It is impossible for ordinary people to pour water into the lithography machine, but if those lithography machine manufacturers hear such a sentence, it will be a matter of minutes to make it.

Qi Lei was holding the phone and stood there in a daze, he didn't come back to himself for a long time, his brain was running fast.

Li Hanhan was dressed in home clothes, and came out of his room with a fruit peel in his mouth.

Seeing Qi Lei standing motionless in the living room, he went up to look around, waved his paws in front of his eyes, "Oh!"

Youyou sighed, "How good would it be if you were stupid?"

Qi Lei came back to his senses, and glared at her, "Get lost!"

Li Hanhan didn't move, "Hungry."

Qi Lei, "I'm busy!"

"Oh, then I'll cook instant noodles, do you want some?"

Qi Lei, "Add an egg."

While talking, he fell on the sofa and called Paulson.

Paulson was going crazy there, and finally confirmed that it was Qi Lei who hung up on him.

What the hell!If you hang up on me in the middle of the sentence, you are really not human!

Seeing Qi Lei calling in, he immediately put on a straight face, "Qi, you are getting more and more rude, I am very angry!"

Qi Lei said, "Do you want to buy a lithography machine company?"

"Uh..." Paulson was embarrassed, "I want to!"

Qi Lei, "Then I'll send you a family?"

Paulson, "Yes, yes!"

Qi Lei, "Then Nikon!"

Paulsen jumped up, "Don't tease me!"

If the lithography machine market in later generations is dominated by ASML, then the current leader in lithography machines is Japan's Nikon.

Why did EUV LLC appear?It is to fight against Japan's chip industry.And Nikon is the biggest enemy of EUV LLC.

Even at the moment, Japan's chip industry is under the bleak management of Lao Mi, but Nikon is still the key man who holds the lifeline of the global chip.

If Nikon can be obtained, Paulson will be able to wake up from his dreams.

The point is, this thing is not something you can just take it if you say it!

"Qi, don't make such a joke, I will take it seriously!"

Qi Lei didn't talk nonsense with him at all, "The first step, the two of us have to be technical masters."

Paulson, "..."

Qi Lei, "Find a newspaper and spread the news that EUV LLC is developing a new generation of lithography machines."

Paulson, "Are you sure?"

Qi Lei, "Too sure."

Brother is going to be a shit stick.

……

Chapter 572

Qi Lei wants to be a shit stirrer, how can he have the time to take care of Master Tuo?

Besides, on Tuo Ye's side, although Qi Lei believed in his ability, this matter could not be done in a day or two.Maybe Qi Lei has been released, but Master Tuo hasn't dismissed his work yet!

During this period of time, it is just right for him to concentrate on studying the lithography machine.

So, the world is so wonderful, and you don't know which seemingly useless cold knowledge will become your lever to move the world.

For the new photolithography technology, Qi Lei really knows three words - wet etching method.

However, for a dirty person, as long as these three words appear at the right time and at the right place, those three words are enough.

After hanging up the phone with Paulson, Qi Lei still nestled on the sofa thinking about things, and slowly conceived how to be a shit-stirring stick.

Li Hanhan cooked the instant noodles and brought them to Qi Lei, he also ate unconsciously.

He didn't take away the bowl after eating, and continued to sit there without moving.

At night, Sister Hanhan thought that she could always have a good meal, right?

However, Qi Lei obviously still hasn't come out of his own world, this time he moved, but he was holding a pile of manuscript paper to write and draw, Sister Hanhan couldn't understand at all.

He had no choice but to continue cooking the instant noodles, and thoughtfully added an extra ham sausage to Qi Lei.

In this way, three days passed.

Yang Xiao became anxious on the phone, "Li Hanhan, you don't really eat instant noodles for four days, do you?"

Qi Lei's cell phone was out of battery a long time ago, and he didn't charge it, so everyone could only know whether Qi Lei was dead or not through Coco Lee's cell phone.

Several people over there expressed deep sympathy for Coco Lee.

Tang Xiaoyi even sighed, "How big a hole does grandson have to dig?"

In the past, Qi Lei also "downtime" frequently, and every time he had a big move, but never lasted for such a long time.

And Coco Lee couldn't take it anymore, she vomited sour after eating the instant noodles.

"Qianqian, can you teach me how to cook porridge? I want some porridge!"

opposite,"……"

Look at the poor children.

Fortunately, Qi Lei finally straightened out his thoughts and came back to life on the fourth night.

After one o'clock in the middle of the night, Li Hanhan fell asleep, but did not sleep well.

Treating her stomach badly these past few days has tortured Sister Hanhan to the end, and she's hysterical.

She felt movement in the kitchen, as if Qi Lei was cooking.

And, that scent!

There are ribs, eggplant sauce, and chicken stew with mushrooms?

well!Lao Qin didn't treat Qi Lei badly, he brought in a lot of living supplies, but it's a pity that this girl's life is too rough, so she can only feel wronged and sleep in the refrigerator with those chickens, ducks and fish.

Ugh……

But, something was wrong, Sister Hanhan really smelled it.

Ji Ling sat up, quietly left the room, and saw Qi Lei just coming out of the kitchen, holding a large bowl of stewed chicken with mushrooms.

Sister Hanhan almost burst into tears, "Qi Shitou, are you sick? It's the middle of the night, what are you doing?"

Qi Lei bared his teeth and smiled, "Would you like some food?"

Li Hanhan said viciously, "Don't eat! Lose weight!"

Qi Lei, "Ask again, eat something..."

"Eat!" Without waiting for Qi Lei to finish speaking, Sister Hanhan rushed forward, "I'll serve the meal!"

A piece of chicken is better than countless in the world...

Sister Hanhan enjoyed it, "I'm alive! I'm alive!"

I asked again, "It's the middle of the night, what are you fussing about?"

Qi Lei glanced at her, but didn't speak.

He was thinking about things these days, and he wasn't really stupid. He couldn't stand the three meals of instant noodles a day.

Pushing the pork ribs in front of Li Hanhan, "Eat this, the child has suffered a lot these days."

Li Hanhan said indifferently, "Hey, it's okay!"

She rarely sees Qi Lei in this state. In fact, in Coco Lee's eyes, labels such as the richest man and entrepreneur are far away from the image of Qi Lei in her heart.

Because she hadn't seen Qi Lei working seriously, this time she had seen enough.

Not to mention, he's pretty handsome.

People who work hard are handsome!

……

After a meal, the two of them came alive completely.

Qi Lei looked at the time, turned on the computer, and still had to work for a while.

Li Hanhan ate his full stomach and didn't feel sleepy at all, so he simply watched Qi Lei work.

Looking at the manuscript paper on the coffee table, "You made such a big pile, do you understand?"

While opening the North American Penguin website, Qi Lei replied: "Understood."

Li Hanhan, "Then what are we going to do now?"

In fact, Qi Lei said that she didn't understand, she was just purely curious.

Qi Lei glanced at the home page news on the webpage, picked up his mobile phone and dialed, "It depends on how Paulson is doing?"

After speaking, the phone was connected.

There was only one sound, and Paulson's roar came from the opposite side, "It's been three days!! Why did you shut down the phone!?"

Qi Lei, "Thinking about something?"

Paulson, "Tell me? I thought you died of the virus!"

Qi Lei, "No kidding, how is it going?"

Paulson was also savvy, with a relaxed look, "What can I do? Isn't it just a small thing? It's already very effective."

Qi Lei gave him one thing, which is to spread the news that EUV LLC is secretly researching a new generation of lithography machines.

This is no difficulty for Paulson, and there is also the Penguin network platform to cooperate.

"This matter is well known to everyone, and even appeared on the Internet in Europe and the United States. The whole world knows that EUV LLC is making big moves."

When Qi Lei heard this, the corners of his mouth rose, "This is what I want!"
