Chapter 121 EUV!
Back to his base, Kang Chi took out the graphics card that had been sealed for a while from his safe, and fell into deep thought while looking at the system panel of the graphics card.

The 14nm chip process seemed to be an unattainable black technology for Kang Chi a year ago.
But after more than a year of development, he, who has established a certain reputation in the domestic science and technology field, can’t help but start to think about whether it is necessary to analyze the technology of a 14nm lithography machine…
Looking at the entire Chinese chip industry, with the strong support and development of the country, most of the technologies have actually been conquered.
The upstream raw materials are from Dahan Silicon Industry,
The midstream key equipment etching machine is from Zhongwei,
They have mastered the 5-nanometer etching process and have become one of the world’s top five etching machine suppliers,
Even the world’s largest wafer factory, Taiwan Electromechanical, is purchasing etching machines from Zhongwei.
In the field of photolithography, China is actually making progress,
For example, Wu Lihong is mainly responsible for the research and development of photoresists, and has made certain breakthroughs.
At the same time, after learning the lessons of the failure of silicon wafers, photoresist material suppliers such as Shin-Etsu Chemical have changed their thinking and no longer raise prices and limit quantities as before, which puts China too tight. Instead, they have started the road of price reduction and promotion.
So at least in the current situation, the research and development of photoresists is no longer urgent.
The rest is the most familiar photolithography machine.
The photolithography machine is indeed the most difficult thing in wafer manufacturing, but with the efforts of countless Chinese scientific researchers, one after another technological peak has been conquered.
It is only a matter of time before EUV photolithography machines are conquered.
As the only company in the world that can produce EUV extreme ultraviolet photolithography machines, ASML CEO Lao Wen’s remarks are the most realistic portrayal of China’s photolithography machine research and development process.
At the beginning, he said: “Even if the drawings of the photolithography machine are given to the Chinese, the Chinese cannot manufacture advanced photolithography machines.”
Later, the supply of photolithography machines was cut off, and China began to fully develop photolithography machines and achieved frequent successes.
This guy quickly changed his words and said: “In fact, the laws of physics are the same all over the world. There is no reason why the Chinese cannot make it.”
The change of face is so fast that you can go to perform Sichuan Opera…
At the same time, in order to keep the Chinese market, they also exported DUV photolithography machines to China crazily.
Based on the above analysis, what China really lacks at present is not the low-end DUV lithography machine, but the EUV lithography machine with a high-end process within 7 nanometers.
This is not only reflected in imported lithography machines, but also in domestic lithography machines.
Currently, Magic City Microelectronics can already mass-produce 90nm process DUV lithography machines,
28nm DUV immersion lithography machines have also had engineering prototypes, and mass production is just around the corner.
Once the immersion technology is thoroughly mastered, it will become a matter of course to continue to compress the process.
For example, the 14nm process graphics card in Kangchi’s hands can be achieved by adding a dual workbench mode on the basis of the 28nm DUV immersion lithography machine,
Therefore, it belongs to the technology that other domestic R&D teams may soon be able to break through.
So from the perspective of necessity, it is no wonder that Kangchi would consider whether it is necessary to analyze it.
With Kang Chi’s current achievements, even if he built an EVU lithography machine, everyone would be surprised, but they would definitely not think he was an alien species…
Thinking of this, Kang Chi decisively chose to upgrade this graphics card!
General experience -3196!
With a faint light flashing, the appearance of this graphics card changed again.
[Item: Silicon Crystal Image Processor]
[Manufacturer: Kang Chi] [Item Level: 8]
[Experience: 0/9600]
[Item Status: Intact]
[Item Parameters: 9 nanometersProcess technology, main frequency 1.6GHz, 12GB DDR6 video memory]
[Analysis project: analyzable]
[General experience: 60042]
[Mastery points: 43.6]
9 nanometers?
This process is a bit ambiguous…
It is a process that can be made by both EUV and DUV.
However, the minimum 7nm is only the theoretical minimum process node of the immersion DUV lithography machine, which can only be achieved by squeezing the technology to the extreme.
With the high level of the system, it should not be so stingy to squeeze a technology to such an extreme for itself, right?
So this 9-nanometer process is most likely made by the EUV lithography machine.
Kang Chi opened the analysis panel and saw that it said that the ‘9-nanometer lithography machine manufacturing process’ required 40 mastery points, which was 10 points more than before, which further confirmed Kang Chi’s guess.
Fortunately, Kang Chi had worked on a lot of lens production lines and oil extractor parts production equipment during this period, earning more than ten mastery points.
Otherwise, he might not be proficient enough to analyze this thing this time…
Mastery points -40!
As Kang Chi chose to analyze,
A huge amount of information swept into his mind like a wave.
However, although the amount of information was large and the duration was very long, the pain it brought to Kang Chi was not as strong as the analysis of oil extractors.
The main reason is probably that Kang Chi had read a lot of professional literature on lithography machines before, and analyzed the lens production line of Daqin Optics and the polishing and grinding process of silicon wafers, which gave him a certain accumulation of optical knowledge.
Therefore, when this information was infused, many knowledge points actually overlapped, but this analysis connected all the knowledge points in series and filled the gaps in between.
After the analysis, it took Kang Chi two hours to sort out all the knowledge points of EUV lithography. By this time, it was already two o’clock in the morning, and his stomach began to growl.
Kang Chi hurried to the restaurant outside, found the cake and milk in the refrigerator, and ate them voraciously.
”Dr. Kang?”
A voice suddenly came from behind him, scaring Kang Chi so much that the milk in his hand spilled on his pants.
He looked back and saw Chen Hai’s face pressed against the glass outside, looking inside, looking quite weird and scary…
Kang Chi quickly opened the anti-peep glass window and complained to Chen Hai: “It’s the middle of the night, can you not scare me?”
”Ahem… Sorry, who told you to use this anti-peep glass and not turn on the light? I’m not sure if it’s you or a mouse… Why haven’t you slept yet so late?”
”I have insomnia and dream a lot and don’t want to sleep.”
”Huh? That won’t do. The body is the capital of scientific research. Do you want me to apply for a private nurse for you? The medical skills are absolutely superb, and I guarantee that you will sleep comfortably every day.”
”???”
Kang Chi always felt that what this guy said was a bit weird, but he couldn’t find the problem.
”Forget it, if I really have insomnia every day, I will find a way to solve it myself… I’m going to sleep.”
After saying that, Kang Chi closed the window and went upstairs to wash up and go to bed.
Chen Hai was stunned on the spot, then shook his head with some regret, and said, “I’ll solve it myself.
How unkind…
The next day, Fang Qiming, under Kang Chi’s instructions, followed several trucks to Kang Chi’s house and transported a third-generation lens production line of Daqin Optics.
Fang Qiming, who had been holding back all the way, couldn’t help but come up to Kang Chi as soon as he jumped out of the car and asked: “Didn’t you just upgrade the production line? Why are you transporting it here again…Are you going to continue upgrading?”
Kang Chi nodded: “Since we are going to build a lithography machine, the first thing we need to break through is the lens and coating process.”
