Technological power starts with upgrading lenses.

Chapter 121 EUV!

Back at his base, Kang Chi took out the graphics card that had been gathering dust for some time from his safe, and looked at the system panel of the graphics card and fell into deep thought.

The 14-nanometer chip manufacturing process seemed to be an unattainable black technology for Kangchi a year ago.

But after more than a year of development, he has established a certain reputation in the domestic technology field, but he can't help but start to think about whether it is necessary to analyze the technology of a 14-nanometer lithography machine...

Looking at the entire chip industry in China, with the strong support and development of the country, most of the technologies have actually been overcome.

The upstream raw materials are supplied by Dahan Silicon Industry.

The key equipment in the midstream is the etching machine, Zhongwei.
  They have mastered the 5-nanometer etching process and become one of the top five etching machine suppliers in the world.

Even the world's largest wafer fab, Electromechanical, is purchasing etching machines from Zhongwei.

In the field of lithography, China is actually making progress together.
  For example, Wu Lihong is mainly responsible for the research and development of photoresist, and has already achieved certain breakthroughs.

At the same time, photoresist material manufacturers such as Shin-Etsu Chemical, after learning from the failure of silicon wafers, have changed their thinking. They no longer raise prices and limits to push China too hard as before, and instead start price reduction promotions. the road.

So at least judging from the current situation, the research and development of photoresist is no longer urgent.

The rest is the photolithography machine that people are most familiar with.

The lithography machine is indeed the most difficult thing in wafer manufacturing, but with the efforts of countless Chinese scientific researchers, one after another technological peaks have been conquered.

It is only a matter of time before we conquer the EUV lithography machine.

As the only company in the world that can produce EUV extreme ultraviolet lithography machines, ASML CEO Lao Wen’s remarks are the most realistic portrayal of China’s lithography machine research and development process.

At the beginning, he said: "Even if you give the drawings of the lithography machine to the Chinese, the Chinese will not be able to make an advanced lithography machine."

Later, the supply of photolithography machines was cut off, and China began to fully develop photolithography machines and reported frequent successes.

This guy quickly changed his mind and said: "Actually, the laws of physics are the same all over the world. There is no reason why Chinese people can't create them."

She can change her face so fast that she can even perform in Sichuan Opera...

At the same time, in order to maintain the Chinese market, they are also frantically exporting DUV lithography machines to China.

Based on the above analysis, in fact, what China is currently lacking is not mid- to low-end DUV lithography machines, but EUV lithography machines with high-end processes within 7 nanometers.

This is not only reflected in imported lithography machines, but also in domestic lithography machines.

Currently, Modu Microelectronics is ready for mass production of 90nm process DUV lithography machines.

The 28nm DUV immersion lithography machine already has engineering prototypes, and mass production is just around the corner.

Once you have thoroughly mastered the immersion technology, continuing with the compression process will become a matter of course.

For example, the 14nm process graphics card that Kangchi has can be achieved by adding a dual workbench mode based on the 28nm DUV immersion lithography machine.

Therefore, it is a 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.

And with Kang Chi's achievements today, even if he builds an EVU lithography machine, although everyone will be surprised, they will definitely not think that he is an alien species...

Thinking of this, Kangchi decisively chose to upgrade this graphics card!

Universal experience-3196!

With a flash of light, the appearance of this graphics card changed again.

[Item: Silicon Image Processor]

[Manufacturer: Kang Chi] ˆ ˆ [Item Level: 8]

9 nanometers?

This process is a bit ambiguous...

It is a process that can be produced by both EUV and DUV.

However, the minimum 7nm is, after all, only the theoretical minimum process node of the immersion DUV lithography machine, which can only be achieved by pressing the technology to the extreme.

With the system's high level of competency, he shouldn't be so stingy and squeeze a technology to such an extreme for himself, right?

Therefore, this 9-nanometer process is most likely made by EUV lithography machines.

Kang Chi opened the analysis panel and saw that it said that '9-nanometer lithography machine manufacturing process' requires 40 proficiency points, which is 10 points more than before, which further supports Kang Chi's guess.

Fortunately, during this period, Kangchi developed a lot of lens production lines and parts production equipment for oil-mining insects, and earned more than ten points of proficiency.

Otherwise, I may not be proficient enough in analyzing this thing this time...

Mastery points -40!

With Kangchi Select Analysis,

A huge wave of information swept into his mind crazily like a wave.

However, this time's knowledge infusion, although it contained a large amount of information and lasted for a very long time, the pain it brought to Kang Chi was not as intense as the oil-mining insect.

The main reason is probably that Kang Chi had read a lot of professional literature on photolithography machines before, and also analyzed Daqin Optics' lens production line and silicon wafer polishing and grinding process, which gave him a certain accumulation of optical knowledge.

Therefore, when this information is poured in, many knowledge points actually overlap, but this analysis connects all the knowledge points and fills the gaps.

After the analysis was completed, Kangchi spent two hours to initially sort out all the knowledge points about EUV lithography machines.
  It was already two o'clock in the morning, and his stomach began to growl.

Kang Chi quickly went to the restaurant outside, found the cake and milk in the refrigerator, and ate it hungrily.

"Dr. Kang?"

A voice suddenly came from behind him, scaring Kang Chi so much that the milk in his hand spilled onto 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 privacy glass window and complained to Chen Hai: "It's the middle of the night, can you not scare people?"

"Ahem... I'm sorry, who asked you to make this kind of privacy glass without turning on the light? I'm not sure if it's you or the mouse... Why haven't you fallen asleep so late?"

"Insomnia, lots of dreams and no desire to sleep."

"Huh? That's not possible. Your body is the capital of scientific research. Do you want me to help you apply for private care? My 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 strange, but he couldn't figure out what the problem was.

"Forget it, if I really suffer from insomnia every day, I will find a way to solve it myself... I'll go to sleep."

After saying that, Kang Chi closed the window and went upstairs to wash up and go to bed.

Chen Hai froze on the spot alone, and then shook his head with regret.
  Solve it yourself,

How hurtful to Tianhe...

The next day, under Kang Chi's instructions, Fang Qiming followed several trucks to Kang Chi's house and transported a third-generation lens production line from 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 Kang Chi: "Didn't you just upgrade the production line? Why do you have to transport it here again... Are you planning to continue the upgrade?"

Kang Chi nodded: "Since we want to build a photolithography machine, the first thing to break through is the lens and coating process."
