Rebirth: Dominate The World, Starting From The School Network

again……

"you………………"

He Rongming looked up at the smiling Lu Yi, somewhat speechless.

no way.

So shocking!

too excited!

Tell the truth.

His superiors asked him to form Shanghai Microelectronics and lead the team to tackle the field of domestic photolithography machines.

Although he is full of passion.

But I plunged into this field and understood the difficulty, as well as the gap between the current domestic related technologies and those overseas.

The warm blood in his body felt as if a basin of cold water had been poured on it.

The difficulty of solving the problem is no less than that of the two bombs and one satellite of the last century.

The technological gap is huge, at least 20 to 30 years behind foreign countries.

How to pursue this?

The key is.

If you want to catch up with foreign countries, you must at least have a group!

But in terms of talents, the relevant domestic talent pool is really too small.

Although there are many Chinese overseas who are giants in the field of lithography machines.

However, compared with the domestic treatment and scientific research environment, these experts and experts do not have the spirit of the older generation to give up the favorable treatment and living environment overseas and return to China to devote their lives to the country.

Top talents in related fields are working for foreign companies.

This has led to the continuous advancement of foreign technology in the field of lithography.

However, there are few domestic technical talents and backward technology.

The gap is naturally getting wider and wider, making it impossible to catch up.

Science and technology are primary productive forces.

but!

Talent is the primary productive force in the development of science and technology!

It comes down to it.

It is still the case that China did not pay much attention to the semiconductor industry in the early days, resulting in insufficient reserves of talents.

Now it is time to develop the semiconductor industry, but it turns out that no one can be found and no one is available.

It’s hard for a clever woman to make a meal without rice!

Yin Zhiyao saw He Rongming's appearance.

I was also very strange and curious in my heart.

What exactly is this information?

He actually made He Rongming lose his temper like this!

then.

He snatched the information from He Rongming's hand and read it.

First he frowned and looked confused.

Then his brows relaxed and he looked slightly happy.

At the end, his face was full of shock and horror.

Same as He Rongming.

“This…………you…………”

Yin Zhiyao looked up at Lu Yi, who was sitting across from him, and stammered for a long time without uttering a complete sentence.

Although he is engaged in etching machines.

But he also knows a lot about some technical principles of photolithography machines.

and.

He understands the technical details better than He Rongming.

so.

After reading this information, I was only a little more shocked than He Rongming.

According to the content of this information, the problem of domestic lithography machines getting stuck will be solved?

If this news gets out, I'm afraid the entire industry will take action.

Because as far as he knows.

ASML is currently conducting technological breakthrough research on extreme ultraviolet light sources and has made some progress.

Once ASML achieved a phased breakthrough in extreme ultraviolet light sources.

Then the lithography machine will be upgraded from DUV to EUV.

The technical limit that the fourth-generation ArF193nm light source immersion stepper DUV lithography machine can achieve is the 7nm process.

EUV uses an extreme ultraviolet light source with a wavelength of 13.5mm. Because the thinner the light source, it can naturally carve finer circuits and can break through to below the 7nm process.

in chip design and manufacturing.

Nano represents the distance between transistors in a chip.

With the same size, the number of transistors contained in a 7nm process chip is almost twice that of 14nm!

The number of transistors directly determines the performance of the processor.

The more transistors there are, the greater the processor's ability to parse.

The higher the precision of the chip, the smaller the size will be, and the corresponding power consumption and heat will be smaller.

Low-precision chips can meet the needs of heavy industrial production, but they absolutely cannot meet the needs of mobile phone technology!

Mobile phones are different from cars. There is only so much space inside, so heat dissipation is the first major problem.

The smaller the process, the smaller the space occupied, and the better the heat dissipation will be.

If we talk about 7nm, it can still be developed without EUV lithography machine.

Well at 5nm, this won't be possible.

In the case of EUV lithography machines, many layers also need to be realized through multiple exposures.

And for DUV lithography machines.

If you want to reach the limit of 7nm, you need multiple exposures.

Most DUV lithography machines use ArF excimer laser with a wavelength of 193nm, or KrF excimer laser with a wavelength of 248nm.

The limit range of a single exposure is between 128nm and 90nm.

Theoretically, the resolution doubles every time the exposure is doubled.

Although multiple exposures can increase the accuracy to a maximum of 7nm, it does so at the expense of yield rate!

With almost every repeated exposure, the chance of damage doubles.

If you want to create a 7nm process chip with a DUV lithography machine, you need at least 16 exposures!

Not to mention whether 16 consecutive exposures can be successful.

Even if it succeeds.

The yield rate must also be frighteningly low.

As a result, costs will inevitably increase dramatically.

How competitive can a 7nm chip produced at such a huge cost be?
