Technological power starts with upgrading lenses.

Chapter 147 Qin Guang No.

Fujita Yoshiki's assistant, like the audience, thought the press conference was about to end. He picked up the remote control and was about to turn off the projector, but he was suddenly stunned.

At the Jianeng headquarters in Yanjing and Ni Kang headquarters in Shanghai,

Saito Yushi and Osaki Hisaku also stood up almost at the same time, gaping at the close-up of the live broadcast.

As for ASML CEO Lao Wen, he was having a luxurious party on a private yacht in the South Pacific and enjoying a happy Christmas vacation.

He did not realize at all that a press conference that was about to change ASML's industry monopoly was being held in the distant east.

In the field of lithography machines, there are only four companies in the world, and ASML is the leader. It can manufacture all lithography machines from ultra-high-end to low-end.

Ni Kang is the second oldest, and can build high-end 7-28nm ArF immersion lithography machines.

Finally, there are Cannon and Modu Microelectronics, which can build 90-nanometer low-end lithography machines.

But today, this pattern will undergo earth-shaking changes!

[Qin Guang No. 1 EUV lithography machine]

In the live broadcast room of Daqin Optics, the photographer had zoomed in on the camera to capture the text and LOGO printed on this blockbuster product!

"EUV lithography machine? Am I dreaming?"

"Damn it, it's a photolithography machine! Daqin Optics actually built a photolithography machine!"

"Really or not? My heart can't bear your jokes!"

"..."

After a moment of silence, the discussion finally began, and then the voices became louder and louder.

Surprised cheers echoed back and forth in the empty venue of the Bird's Nest.

Although there were less than a thousand people present, the excitement was nothing compared to the moment a goal was scored in a football match.

"EUV lithography machine! We can build EUV lithography machine!"

In a university dormitory, students who were watching the live broadcast stood up excitedly, pointed at the computer screen and yelled at their roommates, "Quick, watch the live broadcast of Daqin Optics! They have built an EUV lithography machine!"

When the roommates who were playing black games heard this, they immediately didn't even care about starting a group. They immediately threw away the mouse in their hands and gathered around.

"Holy shit, is this really an EUV lithography machine? Is Daqin Optics so awesome?"

"I feel like the two words "f*ck, awesome" can no longer describe my inner excitement!"

"Master Kang was able to hold back this ultimate move. All I can say is - well done!"

"At this moment, I just want to go crazy@老MCommerce Department and Lao Wen!"

"..."

After a brief lull, the barrage in the live broadcast room started to spread like crazy, and the number of people in the live broadcast room directly exceeded one million.

The rising popularity quickly attracted the attention of the operators of various platforms. After entering the live broadcast room, they were briefly absent-minded, and then quickly pinned the live broadcast room to the top of the homepage.

As a result, the traffic from all major platforms flowed crazily into Daqin Optics' live broadcast room. Because there was no preparation in advance to allocate bandwidth, the screen even experienced freezes.

The semiconductor giants in the second row of the auditorium were almost in a state of despair at this moment.

In fact, when Kang Chi invited them over, in order to give them a small 'surprise', he did not disclose the information to them in advance.

Except for Dong Jianyuan and Chen Yunming, who vaguely guessed that everyone else came here purely for the sake of Dahan Silicon and Kang Chi. The reason why Dong Jianyuan and Chen Yunming could guess was mainly because Kangchi asked them to make a set of cmos masks, and also borrowed a set of ultra-high-precision CUP masks to test the minimum size of the lithography machine. Process.

But until the truth is revealed, they are just guessing.

Their eyes were fixed on Kang Chi, waiting for his further explanation.

Kang Chi waited until the scene became a little quieter before picking up a cmos photosensitive chip and continued to introduce:

"The chip in my hand is the CMOS sensor on the Wuan camera. The silicon wafer used to make it comes from Dahan Silicon, the etching machine comes from China Micro, and the lithography machine... uses the Qin Guangyi machine behind me. EUV lithography machine!"

"Qin Guang 500 is designed and assembled by Daqin Optics. It is the first EUV lithography machine in China. Its EUV light source system comes from the Changchun Institute of Optics, which can achieve stable output of W-EUV light source, and the optical system is provided by Daqin. Optics is responsible for manufacturing, please look at the big screen.”

As soon as Kang Chi finished speaking, a photo of several Daqin Optics engineers holding up the lenses of a photolithography machine together in a dust-free workshop was shown on the background screen of the inner stage.

"This is the lens of the photolithography machine. Its diameter is as high as 125mm, the mirror roughness is 25pm, and the surface accuracy is only 1.3nm!"

"Finally, there is the two-piece workbench of the lithography machine. It is developed and manufactured by Datang Heavy Industries. The displacement error is 200pm, which can theoretically meet the requirements of 2nm chip manufacturing."

"At the same time, thanks to the 500W power EUV light source, the working efficiency of this lithography machine has reached a manufacturing speed of 180 wafers per hour!"

"After initial testing, the smallest process we can currently achieve is 7nm. However, the photolithography machine is actually just a production tool. As the stacking process improves, there is no problem in further shrinking the process."

Hearing this, both the senior management of Shencheng Silicon Industry, SMIC and Leon Micro couldn't help but look at each other excitedly, and then continued to look at Kang Chi with their own concerns.

Kang Chi's parameter introduction just now was actually meant for them, and ordinary viewers probably wouldn't understand it either.

When it comes to the photolithography machine, the general audience is actually just watching the excitement.

However, while watching the excitement, it can also enhance everyone's national self-confidence. By the way, it can also provide a wave of priceless advertising for Daqin Optics' cameras and lenses.

As for the real target users of lithography machines, they are actually the semiconductor giants sitting in the second row.

They are the ones who will actually pay for the lithography machine.

The biggest curiosity among these big guys at this time is whether Kangchi will directly announce the price of the lithography machine at the press conference.

[Unified selling price in China: 9.9 million RMB]

Kangchi didn't keep them curious for too long, and directly announced the price of the lithography machine on the big screen.

"9.9 million?!!"

"Damn it, is this a live broadcast I can afford to watch?"

"I feel like I'm floating. I watched 9.9 million product live broadcasts without blinking an eye."

"I originally had a few hundred yuan in my pocket and was planning to buy lenses, but the anchor backhanded me and pushed me a lithography machine worth NT$9.9 million?"

"Hahaha, Master Kang's operation is pretty good."

"It's gone, I can't even dream of buying something worth 9.9 million."

"Wait a moment, I'll place my order after I finish this bite of Master Kong's Laotan pickled cabbage!"

"Mr. Kang, please stop inking and upload the link quickly. I haven't tried the interface that will pop up if you exceed the credit card limit."

"..."
