The short videos I watched are from ancient times, and the ancients broke the defense

【The crown jewel of modern industry takes you to understand electron lithography technology. 】

On the sky screen.

New video appears. attracted everyone's attention

"The crown jewel of modern industry? Lithography machine technology?"

When Changsun Wuji saw it, he was stunned for a moment.

"Could it be......Is this the top technology of future generations?"

Thinking of this, he suddenly became interested.

As the saying goes, you can see the leopard in a tube.

Just when he was looking at those local skills, he had already felt it vaguely.

Later generations did not think much of those skills.

He even thought that they were.......Lagging?

But those technologies are in his opinion.

They are all far ahead of the related skills that existed in the Tang Dynasty.

So.

This was called the crown jewel of industry by later generations.

How shocking is it?

Changsun Wuji was looking forward to it.

He felt vaguely.

This is called electron lithography technology.

Perhaps it will far exceed his knowledge!

Da Qin plane.

Ying Zheng also saw the video title in the sky at this time.

There was a hint of curiosity in his eyes

"industry? What is industry?"

Next to me.

Li Si thought about it.

"Is it like the machine of later generations?"

In the video just now, although what is taught is the way of indigenous craftsmanship, during the demonstration, the sky screen also showed many pictures of later generations of industrial equipment preparing salt, cement and other materials.

It reminds me of the word industry. It is very It's hard to connect them together.

Ying Zheng also felt that it made sense.

He couldn't help but look forward to it even more.

"Could it be that Tianmu wants to teach me how to build the kind of machine for future generations this time?"

Suddenly, he was full of expectations!

The Ming Dynasty.

Lao Zhu was curious about another question.

"Electron lithography?"

"What is this electron?"

"What is lithography?"

"Lithography?"

"Could it be that light was used to carve the seal?"

Lao Zhu himself was amused by this idea.

Light.

Ethereal.

Insubstantial, elusive.

How could it be used for seal engraving?

As for the electron......

"Could it be referring to the electric light?"

"But the electric light is also ethereal, so how can it be used for seal engraving?"

Lao Zhu is getting more and more confused as he thinks about it.

The sky is in the sky.

The video starts.

【This short video will teach you the basics of electron beam lithography】

【Lithography is a word derived from ancient Greek meaning to print with stone】

【Using this technique, a pattern is first carved into the stone, then the stone is coated with ink and then stamped onto a substrate such as paper.987 】

The video begins.

Let’s briefly introduce what photolithography is.

And when I saw this introduction.

Suddenly many ancient people laughed

"I thought it was some unimaginable technology, but this is it?"

"Isn’t this just printing? Even if there are not a thousand stores in our Song Dynasty, there are still 800 such shops. Is this worthy of being praised by future generations?"

"It seems that the so-called technology of future generations is nothing more than this"

"The anticipation was in vain."

Everyone shook their heads and dismissed it.

However, since it can be called the crown jewel of industry by Tianmu.

Will this electronic lithography technology really be as simple as they thought?

Of course not.

Next..They will see a microscopic world that they have never been exposed to before!

【Today, the ancient word lithography has been given a completely different meaning.】

【Nowadays, when people mention lithography, the first thing most people think of is the lithography machine.】

【So, what is a lithography machine?】

【Why is it called the crown jewel of human industry? 】

In the sky.

As the video goes on.

Photos of the lithography machine were released.

Although it is called a machine.

But the lithography machine is extremely large.

Its volume is approximately more than 100 cubic meters.

Almost the same size as a bus

【This is the most sophisticated instrument currently known to mankind - EUV engraving machine】

【An EUV engraving machine weighs 200 tons and is worth 120 million】

【Because of its sophisticated structure, the transportation process alone requires three Boeing 737 aircraft and 40 containers, and the installation and commissioning alone takes a year.】

【Someone asked whether building a photolithography machine is more difficult than building an atomic bomb?】

【The answer is yes】

【Today, with advanced technology, there are many countries that can manufacture atomic bombs, but there is only one country that can manufacture EUV engraving machines.】

【An EUV engraving machine consists of 100,000 parts. There are more than 5,000 manufacturers involved in photolithography machine parts, and suppliers are distributed in more than 30 countries. It has gathered almost the world's top technical talents and represents the pinnacle of human technology.】

【So you now know how difficult it is to make a chip, right? ]

100,000 parts.

More than 5,000 companies participated.

Supplied in more than 30 countries.

It has gathered almost all the top technical talents in the world.

When you see these introductions in the canopy.

The ancients who originally had some contempt for him.

Now I can no longer laugh at all.

And immediately.

A new question haunted their minds.

Such a complex and sophisticated machine.

What exactly is it used for? soon.

Tianmu gave the answer

【The EUV lithography machine can produce light with a wavelength of 13.5 nanometers, which is 14 times shorter than the DUV lithography machine. Therefore, it can be used to make smaller transistors.】

【Let’s first briefly understand the working principle of EUV lithography machine】

【First of all, the extreme ultraviolet light it requires does not exist in nature, so this light source needs to be artificially created. This is also the most difficult step in the EUV engraving machine.】

【To put it simply, a 20-kilowatt laser is used to irradiate liquid tin beads in a vacuum environment from a height of three floors. The diameter of these tin beads is only one-third the diameter of a human hair, and they are always in a state of free fall.】

【Laser pulses need to bombard these tin beads at a frequency of 50,000 times per second, causing them to instantly vaporize and evaporate into plasma.】

【The extreme ultraviolet light emitted by these plasmas enters the condenser and is collected】

【The optical system focuses the 13.5nm EUV beam onto the mask through multiple mirrors and reflective optics】

【The chip on the mask is projected onto the silicon wafer coated with photoresist through the projection function of the optical system】

【When the photoresist is exposed to extreme ultraviolet light, it will sol, and soluble and insoluble areas will appear during the development process, thereby forming precise patterns on the silicon wafer.】

【During this process, the light source will be damaged by 30% every time it is reflected, and finally only about 2% of the extreme ultraviolet light can reach the silicon wafer.】

【The most difficult part, in addition to bombarding tin beads to generate extreme ultraviolet light, also requires high-precision optical equipment. ]

Numb.

It’s completely numb!

The Tang Dynasty plane.

Although I don’t understand those mysterious and mysterious professional terms.

I don't understand what photoresist is.

I don’t understand what a silicon wafer is.

But Guangguang is the first step to bombard the tin beads.

It made Li Er's scalp numb with shock!

"Bombarded from a height of three stories at a frequency of 50,000 times per second?"

"And the target is only one third of a hair?"

"this......How can this be done!"

Li Er pulled off a piece of hair.

Looking at the hair that was already extremely thin, he could not imagine at all.

How did future generations control light to bombard things thinner than hair!

And it was still 50,000 per second. times!

And it’s still more than ten meters away!

Wait a minute......They can also control light!

It’s not just Li Er.

Other ancient people fell in the first step of the photolithography machine process.

This method is completely beyond their knowledge. (To read Baoshuang novels, go to Feilu Novel Network!) He is simply more immortal than the legendary immortal!

Ying Zheng murmured:"Is it possible that all future generations have evolved into immortals? Such methods are unheard of!"

Liu Che was dumbfounded:"Is this something a human can do?"

Cao Cao was stunned:"No way! Absolutely not. Maybe!"

Liu Bei felt cold all over his body:"I can even control light. Am I not dreaming?"

Lao Zhu was stunned for a moment.

Then my mind opened up!

"Fifty thousand times per second?"

"If you could control the sword to swing 50,000 times per second, you could chop it down on a Tatar.......hiss!"

【The engraving accuracy of an EUV engraving machine is equivalent to aiming a laser pointer from the moon at a person's finger on the earth. 】

Li Er:? ? ?

Ying Zheng:? ? ?

Liu Che:? ? ?

Lao Zhu:......[]

Everyone was confused again

【Only with this kind of precision can the internal layers of the chip be kept in order.】(cbc)

【We all know that the more transistors inside a chip, the stronger its ability to process information.】

【So we need to cram more transistors into a chip the size of a fingernail】

【A chip can contain more than 10 billion transistors】

【The complexity inside is no less than the layout of a city. ]

Accompanied by video commentary.

A chip is given in the canopy.

The lens focuses on the chip. enlarge...... enlarge......

Keep zooming in...... immediately. coreThe microscopic world is displayed in front of everyone.

When seen after magnifying countless times.

That's less than the size of an average person's fingernail.

There is actually a huge miniature city.

Suddenly.

All the ancients exploded!

"Oh My God! is this real?"

"incredible! Unbelievable!"

"really! How is it possible to carve such exquisite patterns in such a small area!"

"No! More than just patterns! Didn’t you see what Tianmu said just now? This thing can also calculate!"

"miracle! What a miracle!"

More than 10 billion transistors are stacked on the chip in an orderly manner.

To the ancients, this scene was indeed a miracle!

【Look carefully, the transistor structure inside the chip is divided into many levels, and together they form a huge high-speed network.】

【A DUV engraving machine requires thousands of processes to complete the manufacturing of a chip. An EUV engraving machine consumes 30,000 kilowatt hours of electricity every day.】

【The mass production of my country's self-developed lithography machines from 65 nanometers to 22 nanometers has gone through countless practices and technical iterations, but 22 nanometers is a watershed. Although we can also use DUV lithography machines to produce 7-nanometer chips, but with The level of EUV engraving machine manufacturing is still far behind】

【Therefore, if we want to break the bottleneck of lithography machines, we need to break through the 13.5-nanometer extreme ultraviolet technology. Only in this way can we fundamentally break the barriers of lithography machines.】

——"The person who was the first to create a photolithography machine was so awesome!"

——"More than one order of magnitude more difficult than the atomic bomb!"

——"If I build this thing by myself, can I study for free from a junior college to a bachelor's degree?"

——"There are so many talents with 700 points in the country, please work harder!"

——"No matter how difficult it is, we must build our own photolithography machine!"

——"It’s not that only one country can make it, but no country can currently make it alone! But I believe and am sure! Our country must be the first to produce independently!"

——"The splendid mountains and rivers are in good condition, and our countrymen should strengthen ourselves!"

If the high precision of the lithography machine and the technical content required behind it shocked the ancients, then the end of the video and what was said in the comment area made the ancients frown secretly.

The Tang Dynasty Face.

There was a trace of doubt in Li Er's eyes.

"Just now, it was said in the sky that only one country in the future can produce this lithography machine. I thought it was referring to China in the future."

"Didn't expect it to be the case?"

This is too unexpected.

China in later generations is already so powerful.

But it has not been able to build this lithography machine?

There are actually countries in the world in later generations that are more advanced than China?

The Great Qin plane.

Compared to Li Er was just confused.

Ying Zheng looked a little dissatisfied.

"The people of later generations are too unmotivated."

"I have been in China for thousands of years, when have I not been number one in the world?"

"Instead, in later generations, I was outshined by barbarians, which disappointed me."

Ying Zheng is dissatisfied.

In his opinion, outside of China, there are barbarians.

They cannot even compare to a group of barbarians.

Isn’t it a disgrace to our ancestors?

You know when I was the emperor.

There are still a lot of people in the outside world who are just looking for hair and drinking blood!

Just the descendants of those savages.

How dare you be more advanced than my Chinese descendants?

The thought of this.

Ying Zheng was even more unhappy.

On the canopy.

Jump to next video

【Is a cable on an aircraft carrier worth tens of millions? This is how our country actually developed it. 】

The dissatisfaction came to an end.

When new videos appear.

Ying Zheng immediately focused his attention on it.

Looked up.

Cyclorama:

As the video begins.

An aircraft carrier appeared on the screen. at this time.

A fighter jet lands on the deck of an aircraft carrier. when touching the deck.

The fighter hooked a rope on the deck.

The speed decreases rapidly.

Finally landed safely

【This is a rope that only 4 countries in the world can independently produce, and one piece costs tens of millions.】

【The main function of this rope is as shown in the video, it is used to intercept aircraft on the aircraft carrier, so its name is also very simple and clear, it is called the aircraft carrier arresting rope.】

【On an aircraft carrier, the arresting cable is crucial. It greatly reduces the taxiing distance of the aircraft and effectively helps the fighter planes land.】

【So even though it’s just a rope, it can be said to be the most technologically advanced rope in the world.】

【For a long time before, our country did not have this technology to manufacture】

【All the blocking ropes we need need to be purchased from abroad. Not only are the prices very high, but we also often have to look at other people’s faces. 】

See this.

Ying Zheng's face suddenly turned dark again.

"Disappointed, so disappointing!"

"That’s just the photolithography machine. After all, it looks complicated."

"But this simple rope cannot be made by future generations?"

"I am so disappointed!"

Ying Zheng was suddenly deeply shocked.

In his opinion,

China is the kingdom of heaven.

Even in later generations, it must be the world's most powerful country.

But now.

This cannot be achieved.

That cannot be achieved.

Could it be that future generations have fallen behind to this point?

It’s not just Ying Zheng.

At this time, the emperors from other planes, including

Liu Che, Li Er, Lao Zhu, etc., all also looked a bit unhappy.

This is the future of China. level......It seems to be somewhat different from what they expected?

And this time.

What follows in the marquee.

But they were all suddenly startled..
