Back at his base, Kangchi took out the graphics card that had been dusty for a while from his safe, and looked at the system panel of the graphics card in deep thought.

The 14nm 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 science and technology field, but he can't help but think about whether it is necessary to analyze a 14-nanometer lithography machine technology......

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

The upstream raw materials have Dahan Silicon Industry,

The key equipment in the midstream etching machine has Zhongwei,

They have mastered the 5nm etching process and have become one of the top five etching machine suppliers in the world.

Even the world's largest wafer fabs are purchasing etching machines from Zhongwei.

In the field of lithography, China is actually going hand in hand.

For example, Wu Lihong is mainly responsible for the research and development of photoresist, and has also made certain breakthroughs.

At the same time, photoresist material manufacturers such as Shin-Etsu Chemical, after learning the lesson of silicon wafer failure, have changed their thinking, no longer as before, the price increase limit at every turn to force Huaguo too tight, and began to reduce the price of promotion.

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

The rest is the most well-known lithography machine.

The lithography machine is indeed the most difficult 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 the EUV lithography machine is conquered.

As the only company in the world that can produce EUV extreme ultraviolet lithography machines, ASML CEO Lao Wen's remarks are the truest portrayal of the research and development process of Huaguo lithography machines.

At the beginning, he said: "Even if the drawings of the lithography machine are given to the Chinese people, the Chinese people will not be able to make advanced lithography machines." ”

Later, the supply of lithography machines was cut off, and Huaguo began to make every effort to develop lithography machines and received frequent successes.

This thing hurriedly changed his words and said: "In fact, the laws of physics are the same all over the world, and there is no reason why the Chinese people can't make them." ”

The face changes so fast that you can go to Sichuan opera......

At the same time, in order to keep the Chinese market, they also frantically exported DUV lithography machines to China.

To sum up, in fact, what Huaguo really lacks at present is not the low-end DUV lithography machine, but the EUV lithography machine with high-end process within 7 nanometers.

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

At present, Modu Microelectronics can mass-produce DUV lithography machine with 90nm process.

The 28nm DUV immersion lithography machine also has an engineering prototype, and mass production is just around the corner.

Once the immersion technology is thoroughly mastered, and then the process is compressed, it becomes a matter of course.

For example, the 14nm process graphics card in Kangchi's hand can be achieved by adding a dual workbench mode on the basis of the 28nm DUV immersion lithography machine.

Therefore, it belongs to other domestic R&D teams and may soon be able to break through the technology.

So from the point of view of necessity, it is no wonder that Kangchi will consider whether there is a need to analyze it.

With today's Kangchi achievements, even if the EVU lithography machine is built, everyone must be surprised, but they will definitely not think that he is an alien species......

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

General Experience - 3196!

With a glimmer of light, the shape of the card changed again.

[Item: Silicon Crystal Image Processor]

【Manufacturer: Kangchi】

[Item Level: 8]

[EXPERIENCE: 0/9600]

[Item Condition: Intact]

[Item parameters: 9nm process technology, main frequency 1.6GHz, 12GB DDR6 video memory]

[Parse item: Analyzable]

[General experience: 60042]

[Mastery Points: 43.6]

9 nanometers?

This process is a bit ambiguous......

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

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

With the high force of the system, it shouldn't be so stingy and squeeze a technology to such a limit for yourself, right?

Therefore, this 9nm process is most likely made by EUV lithography machine.

Kangchi opened the analysis panel and saw that it said that the '9nm lithography machine manufacturing process' requires 40 mastery points, which is 10 points more than before, which further corroborates Kangchi's guess.

Fortunately, Kangchi has rubbed a lot of lens production lines and parts production equipment for oil extractors during this time, and has earned more than ten points of proficiency.

Otherwise, this time it may not be proficient enough to analyze this thing......

Mastery points -40!

With the analysis of Kangchi's choice,

A huge stream of information swept through his mind like a wave.

However, although the knowledge infusion this time is large and lasts for a very long time, the pain brought to Kangchi is not as strong as the analysis of oil extraction insects.

The main reason is that Kangchi has read a lot of professional literature in the lithography machine before, and at the same time analyzed the lens production line of Daqin Optics and the polishing and grinding process of silicon wafers, which has allowed him to accumulate a certain amount of optical knowledge.

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

After the analysis, it took Kangchi two hours to preliminarily sort out all the knowledge points of the EUV lithography machine.

By this time, it was two o'clock in the morning, and his stomach was rumbling.

Kangchi hurriedly went to the restaurant outside, found the cake milk in the refrigerator, and devoured it.

"Dr. Kang?"

A voice suddenly came from behind him, and the milk in Kangchi's hands spilled on his pants.

When he looked back, he saw that Chen Hai's face was pressed against the glass outside, looking inside, looking quite weird and scary......

Kang Chi hurriedly opened the privacy glass window and complained to Chen Hai: "In the middle of the night, can you not be scary?" ”

"Ahem...... I'm sorry, who asked you to do this kind of privacy glass, and you don't turn on the lights, I'm not sure if it's you or a mouse...... Why haven't you slept so late? ”

"Insomnia, dreams, and don't want to sleep."

"Huh? This is not good, the body is the capital of scientific research, do you want me to help you apply for a private nursing? The medical skills are absolutely superb, and it is guaranteed that you will sleep comfortably every day. ”

“？？？”

Kangchi always felt that what this thing said was a bit weird, but he couldn't find the problem.

"Forget it, if I really have insomnia every day, I'll find a way to solve it...... Slept ang. ”

After saying that, Kangchi closed the window and went upstairs to wash up and sleep.

Chen Hai was stunned alone, and then shook his head with some pity,

Solve it yourself,

How hurtful is it......

The next day, under the command of Kangchi, Fang Qiming came to Kangchi's house with several trucks 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 and ask Kangchi as soon as he jumped out of the car: "Didn't you just upgrade the production line?" Why do you have to ship it again...... Are you ready to continue upgrading? ”

Kangchi nodded: "Since we want to build a lithography machine, the first thing to break through is the lens and coating process. ”
