In general, the technical indicators of the fourth-generation lithography machine are about twenty times that of the third-generation EUV.

This is like the iteration of a carriage and a train, the gap is all-round, the shorter wavelength is just a symptom, and the most amazing innovation is that Xingchen Technology has broken through the physical limit of exposure power.

Ordinary people may not know that from the first generation to the third generation of lithography machines, they are actually the result of miracles.

Take the third-generation EUV as an example, extreme ultraviolet light is a super-powerful electric tiger, and the 250W machine consumes up to 30,000 kWh of electricity every day it works, and it also needs a set of amazing heat dissipation system to assist.

Technology is not enough, power to make up, has always been the logic of the development of lithography machine, before Xingchen technology, no company has really solved this problem, the idea of engineers is usually simple and crude, they want to more accurate exposure effect, they continue to increase the power, make a larger light source generator, polish more sophisticated lenses.

The reason why Xingchen Technology was able to completely solve the problem was that they did not continue the tradition of overexplosion of high-power light sources, but directly used lasers.

In essence, Xingchen Technology's fourth-generation lithography system is a set of laser scattering platforms, which can not only etch silicon wafers, but also develop laser weapons after process improvement.

Of course, there is still a long tech tree to climb from the laser-etched platform to the laser weapon, and it can't be achieved overnight.

"It's laser scattering! The Chinese people used laser technology! ”

"Laser etching at 0.5 nanometers? Doesn't that mean that Xingchen Technology has the ability to advance the chip index to 0.1 nanometer, or even lower? ”

"It's completely unimaginable that if the design side keeps up, they can make as many cores as they need, and it is no longer a fool's dream to cram a 128-core processor into a mobile phone."

"That's awesome, isn't it?"

"Xingchen Technology is awesome!"

Although most of the people who eat melons can't understand the technical parameters reported by Luo Jia, the professionals quickly understand the power of this lithography system.

The lithography technology that has lasted for decades has been reborn, and ultraviolet photoetching is about to withdraw from the historical stage, and the future will definitely belong to the laser etching technology of Xingchen Technology.

Chips, the top products that dominate human science and technology, will reach a new height in terms of technology, one nanometer, zero point one nanometer, and even zero point zero one nanometer chip products, will replace the existing seven nanometer technology, power consumption, processing power, heating, will be improved by leaps and bounds.

The future has come, Huaxia's science and technology colleagues cheered and excited, while the Western world fell into deep fear, they never thought that today's Xingchen technology came out, it is the real fourth generation of technology, and the technical level is so high that it can almost be described as a miracle.

"I don't understand it at all, but so many people send barrage and scatter flowers, is it very powerful?"

As Luo Jia's introduction continued, the people who ate melons were unaware and inquired one after another.

"It's not just amazing, Xingchen Technology is awesome! The fourth-generation lithography technology can be used not only for silicon wafers, but also for more advanced graphene wafers and polymer carbon wafers in the future! It's technology for decades to come! ”

Technology enthusiasts have blown up that the invention of any great technology will not only bring a little change to mankind, but will be an uproar.

Just as the advent of the Kármán vortex technology has completely changed the global energy landscape, the big dogs in Russia and the Middle East have been affected by the collapse of oil prices, and the losses have been extremely heavy, and the people are about to go crazy.

Spreading inland from the three eastern provinces, more and more beautiful Russian ladies came to China to work, it is said that the good quality and low price, while the big dog households were not so lucky, because they could not get visas from China and North America, they had to continue to pour into Europe.

A great cultural and religious change is brewing in the land of Europe, the rapid growth of the number of refugees, so that the European authorities are bitter, they now regret it is a little too late, the magpie's nest dove occupied, the epic drama of vacating the cage for birds, has been unstoppable, the future of Europe, everything is full of unknowns.

Luo Jia paused, with a relieved smile on her face.

It was a lonely speech, there was no host on the scene, and the audience could not hear the crazy cheers, but Luo Jia was still fully engaged, using his imagination to talk about it, from science to literature, and from trade disputes to the rolling history.

"How accurate is high-precision laser etching?" Luo Jia said with a smile: "Accurate to the extent that even the air can't tolerate it, during the exposure process, there can't even be any gas intervention, according to the original practice, ultra-pure deionized water should be used to fill the gaps between the chips, this is the famous immersion lithography technology, the Hisilicon Kirin CPU, Intel CPU, Qualcomm Snapdragon CPU, you are using immersion lithography technology." ”

"Immersion lithography technology is very powerful, but it is also a pity that the patents for this technology are all in the hands of ASML and Neon Nikon in the Netherlands, and it is difficult for late-developing technology companies to do it, obviously, Nikon and ASML will not sell us the patents, so we have to develop our own exposure filling technology."

"You know what's more? To achieve high-precision barrier filling technology, you first need ultra-precision step scanning technology to monitor the constant flow of water molecules! ”

"So, we sent another team to work on the scanner..."

Luo Jia talked eloquently, there were many dry goods in his speech, and there were also many interesting stories, which were not all joyful, but also had a lot of sadness in them.

The difficulty of research and development is unimaginable to ordinary people, in order to bypass Western patents, the lithography machine team has done countless work, assuming that Xingchen Technology is a South Korean company, I am afraid that it will be able to come up with lithography products two years earlier, because the West does not implement a technical blockade on South Korea.

In our country, many technologies cannot be bought with money, and many patents are never granted to us by the West.

"Okay, I'm standing here today, I'm not here to complain to everyone, Xingchen Technology is a tough guy group, no matter how hard it is, we can carry it, it's just that some netizens scolded the incompetent remarks of the scientific research community, which makes me really a little unacceptable, I must say two words."

"We are different, Neon and South Korea only need to pay 80% of their efforts to engage in scientific research, while we have to pay 1,000 percent! This is the truest state of affairs, the scientific community is full of hostility and malice from the West, and it will not change for many years to come. ”

"Well, this is the end of today's speech, I said so much nonsense, in fact, I talked about two things, first, there is no successful case of kneeling and licking the nation in this world, so it is important to maintain self-confidence, and second, we have manufactured the world's first fourth-generation lithography machine, which has laid a foundation for Huaxia's semiconductor road."

The conversation suddenly changed, and Luo Jia said in a mysterious tone, "Speaking of the basics, you may have heard that Ali Group took the lead and vowed never to take the opportunity to poach Huawei's talents, and their own talents are willing to go to Huawei, and they will all let them go." ”

"You may have also heard that many companies in Huaxia have jumped into the bottomless pit of the semiconductor industry without hesitation in order to fight for a breath, Goodix announced that it wants to do RF, Ali's Pingtou brother wants to engage in graphics, and even Tencent, which has no hardware genes, has also gathered a team of people and rushed to surround audio solutions."

"Today you have also seen with your own eyes, Xingchen Technology is not idle, after solving the problem of passive components and lithography machines, the next step is to do masks, do all Chinese underlying machine language, chip logic, description flow, execution unit, command registers and so on."

"However, these actions are all from the corporate world, the real big boss in Huaxia, so far, there seems to be no action."

After that, Luo Jia laughed, and her smile was a little mysterious.

The people who eat melons have speculated that the real big boss in Huaxia naturally refers to the national team.

The national team is different from the people, once the state apparatus is activated, it can't be stopped, and everything will be crushed!

What does Luo Jia mean? Could it be that the national team is going to move!?

These words immediately aroused everyone's great curiosity, but Luo Jia sold a pass and said: "Actually, I just got the news that the national team will make a big move, just half an hour before the live broadcast started." ”

After that, Luo Jia raised his wrist, glanced at the time on the Huawei brand smart watch, and said: "In ten minutes, it will be officially announced at nine o'clock tonight, please wait and see." ”
