Son, how did you become the richest man in elementary school?

However, it is impossible for Gu Xiu to say this, if he did, Liang Sining might vomit blood on the spot.

Shake his head.

Gu Xiu said: "Normally speaking, it does take ten or eight years, but what if Mr. Liang can obtain their technology?"

"You want me to steal a teacher?" Liang Sining was stunned for a moment before realizing it.

Gu Xiu nodded.

"It's impossible." Liang Sining shook his head:

"There are so many technologies, it is impossible for me to learn all of them by myself, and to be honest, I have no chance to get in touch with these sophisticated technologies."

"It is more likely to be exposed to some iterative technologies."

"Those iterative technologies are still several years behind others."

This is the truth.

Overseas is the same as guarding against thieves, guarding against domestic, how can it be casual.

Just let someone steal the teacher?

If you are exhausted, you can also steal some outdated and unimportant things.

But what's the point?

It is still impossible to sit at the same table.

But Gu Xiu smiled:

"If you can't learn it by yourself, call more people."

"As for what you can only learn is iterative technology, that's no problem."

"Let's learn some iteration techniques."

"That's enough."

"After all, here I have a way to overtake on a curve."

"..."

Chapter 405

"Ask more people to steal lessons?"

"Overtaking on a curve?"

Gu Xiu's words made Liang Sining a little confused.

First of all, stealing teachers is a big problem. It is actually very difficult for them to steal their identities. After all, their identities are here.

As for corner overtaking?

"In recent years, our domestic semiconductor industry has basically been standing still, but wafers, design and even etching have been improving."

"And the biggest shortcoming is the lithography machine, which is also the main business of sister Liang Ling's company."

"So, the lithography machine has now become the most difficult problem, and it is also the technology that most restricts the development of the semiconductor industry, right?"

"That's right." Liang Sining nodded:

"The lithography machine has always been a very critical link in the entire chip production, but because of the higher and higher requirements for high precision, the lithography machine has become the most technically tested thing."

Here.

You need to understand the manufacturing process of a chip.

The chip process is complicated and complicated, but it is actually very simple to say simple.

In layman's terms, the process is nothing more than those few.

Create silicon wafers, lithography, processing, packaging and testing.

The first is to create a wafer, and what is needed is naturally silicon. This semiconductor material is between a conductor and an insulator, and its characteristics are very suitable for use as the basic material of a transistor.

Of course, the main reason is that it is easy to extract, and it is almost inexhaustible.

After all, this thing is that after the sand is added to the carbon and burned, the pencil-mounted crystal pillars can be burned out, and then cut into pieces, and then polished to become silicon wafers.

After the wafer is settled, the next step is lithography.

Because semiconductors need to set up circuit nodes and switches one after another, it is necessary to design a reasonable design drawing, and then perform photolithography according to the circuit on the design drawing.

The process is actually easy to understand.

To put it bluntly, it is to apply photoresist on the wafer, then mask the mask according to the design drawing, and finally use the ultraviolet light of the photolithography machine to penetrate the mask, and then dissolve the exposed wafer part.

A groove is exposed.

After that, it is miserly, through ion implantation, the characteristics of the transistor are given.

To put it bluntly here, it is to inject boron and phosphorus, then fill with copper, set up the circuit according to the design drawing, and connect the metal wires.

There are layers upon layers, densely packed like a highway, but basically they are all at the millimeter level.

And finally.

It is the final packaging and testing link. After installing the heat sink and substrate substrate, it is basically a complete CUP.

The whole process looks simple.

Not too complicated.

Even on military equipment, a large piece of silicon can be produced to process ultra-complex data and instructions.

but.

With the progress of the times, the demand is getting higher and higher, and this seemingly uncomplicated thing has become more and more complicated.

The easiest thing to say.

That is, the size of the mobile phone chip basically remains the same every year, but the circuits inside are becoming more and more complex. On a small wafer, more and more work needs to be done and more instructions processed.

This requires that there are more circuits on a chip, and more precise and subtle channels.

And lithography has become a very important part of it, and it is also a very critical link from the very beginning.

Photolithography technology determines that more things can be done on this chip.

At present, the top technology in the world has reached the 193nm lithography technology, and now even Nikon and the like are still studying how to break through the 193nm technology.

It is naturally different from the 7nm of later generations, but in this era, 193 itself is an insurmountable threshold.

Don't look at it seems to be much worse.

But domestic...

What is 193?

Don't dare to think, don't dare to think at all.

After all, lithography technology has been stagnant for so many years, let alone 193nm, even 265nm is still a huge threshold, which stops many people.

"This thing needs a little bit of grinding, a little bit of research and development, and a little bit of research."

"Like the neon side."

"Countless manpower, material resources and resources are all invested in order to win the supremacy."

"As for overtaking on corners, there are no corners on this track."

"And we are too far behind. To put it bluntly, even if we have obtained other people's technology now, let us study this technology. If we want to catch up with their current progress, it may take a few years."

"A few years later, they may have already broken through to below 150nm. If they want to catch up, they can only continue to work hard."

"There is no such thing as overtaking on a curve."

Liang Sining said with a sigh.

Although he didn't want to admit it, but the facts were in front of him, even if it was hard to say, he could only admit it.

Domestic technology, compared with overseas powers.

The worst is still a little far.

"I don't deny that this thing needs hard power, but I think hard power is very important, but it's not impossible to overtake on a curve."

Gu Xiu shook his head, he didn't give Mr. Liang a chance to refute, and said now:

"Actually, Mr. Liang, when you talked about the semiconductor industry with me before, I read a lot of related reports myself."

"Exactly, I happened to have read some related professional reports on lithography machines."

"It is reported that 193nm is currently a headache for many companies."

"And according to the Rayleigh equation, R=k1*(λ/NA)"

"To reduce the resolution R of the lithography machine, you need to reduce K1 or λ, or increase NA."

"And the most direct and effective method is to reduce the wavelength λ of the light source..."

Having said that, Gu Xiu paused.

Because he found that Liang Sining was looking at him blankly, and there seemed to be something strange in his eyes.

"Am I wrong?" Gu Xiu scratched his head.

He repeatedly confirmed that some materials he had read in his previous life confirmed that his memory was correct.

Am I being scammed by the media?

Just when Gu Xiu was thinking about whether he had said something wrong and was making trouble, Liang Sining suddenly asked excitedly:

"You... what magazine did you read about this kind of thing?"

"This..." Gu Xiu was dumbfounded, and casually said, "Oh, I saw it on TV, from a teacher in Hawaii."

"On TV? The teacher in Hawaii?" Liang Sining was at a loss, feeling that the words were a bit confusing.

"Ahem, how do I know this is not important, is it?"

Gu Xiu coughed dryly.

"In fact, it is also very important that such reports are completely professional reports. If we can see them, they may give us a lot of impetus."

Liang Sining muttered, but still nodded: "Go ahead, what else was said in the report?"

"The report said that reducing the wavelength λ of the light source is the most direct and effective way, but now this road has basically come to an end, at least in the short term, there is no breakthrough." Gu Xiu said.

Liang Sining nodded and said seriously:

"That's the reason. We also have limitations in this regard. Reducing the wavelength λ of the light source has always been the direction we are working hard on."

"Compared with overseas countries, we still have a big gap."

"I didn't expect that overseas has reached a bottleneck. It seems that this road is indeed very difficult."

"It's really difficult."

Gu Xiu thought of the purple aurora of the later generations of ASML, which was created by gathering the top teams in the world, even including several super teams in the United States who study world peace.

but……

"This stuff is really difficult, and it is destined to be a difficult path, but if there is a huge breakthrough in the short term, there is an easier way."

"What method?" Liang Sining asked.

"Junior high school physics knowledge!"

"Huh?" Liang Sining's expression turned weird instantly, and he even suspected that Gu Xiu was deceiving him.

Available in the next second.

Liang Sining's complexion changed.

Because he heard, Gu Xiu spit out two words softly:

"refraction!"
