So on January 17, 2004, the two sides officially held a press conference in the large conference hall of the headquarters of the Summer Academy of Sciences.

In the face of the joint press conference held by Xia Academy of Sciences and Shuguang Technology, domestic and foreign reporters naturally felt that something big had happened.

So before the press conference was officially held, the reporters on the scene were all excitedly discussing what news would be released next.

"This time, Shuguang Technology and Xia Academy of Sciences held a joint press conference, and I always feel that this time there will be big news that shocks the world."

It was a young journalist with glasses and a lot of huza who spoke.

In this regard, a young female reporter at the scene also said excitedly:

"I also feel this way, after all, if nothing else, this is Xia Keyuan.

Xia Academy of Sciences is a place where my high-end intelligence gathers in Daxia, and the collection of high-end R&D forces in Daxia, at this time, the cooperation between Xia Academy of Sciences and Shuguang Technology is definitely an unusual cooperation.

So there's definitely big news this time, and it looks like we're going to get a big headline. ”

In the face of the female reporter's words, the other reporters at the scene also nodded, and then showed anticipation.

After all, who wouldn't want to be a journalist who wouldn't want to be covered with the kind of headline-level big news.

At this time, there was a commotion outside the door.

In this regard, the reporters instantly lifted their spirits, and then looked in the direction of the door.

I saw Lin Chen outside, walking into this super-large conference hall with an old man wearing glasses, a group of old people and a young man.

"That's Dean Lu of the Xia Academy of Sciences, and the old people and a young man next to me should be academicians if I didn't expect, I should have interviewed their news before."

At this time, it was a middle-aged reporter in his forties, and he knew that he was a famous CCTV reporter by looking at the icon of CCTV TV on his microphone.

Seeing this, the surrounding reporters instantly became excited.

At this time, the president of the Summer Academy of Sciences and Lin Chen stood together, and there were several academicians beside him, it seems that the cooperation between the Summer Academy of Sciences and Shuguang Technology must not be simple.

This Daxia academician is just a lifelong honorary title, but it is not easy to get this title, because the average number of academicians can only be born in a year.

Since the founding of the People's Republic of China, there have been only a few hundred academicians who have accumulated and survived over the years, and the average probability is one in a million, which shows how difficult it is to become an academician.

In this case, becoming an academician means that you have reached the pinnacle of the research and development field, which is the highest goal pursued by countless researchers throughout their lives.

"......Click, click

When Lin Chen, Dean Lu of the Xia Academy of Sciences and several academicians walked on the stage, the reporters had already pressed the cameras in their hands and filmed the scene of them walking into the door.

In this way, with the flickering of lights, it took dozens of seconds to finally reach the center of the stage.

"I am very pleased that the press guests participated in this press conference, and the content of this press conference is to officially announce the cooperation between our Xia Academy of Sciences and Shuguang Technology."

At this time, it was Dean Lu of the Xia Academy of Sciences who spoke, and I saw that Dean Lu paused at this time and then said:

"As for what this cooperation is, the main content of the cooperation is that we will jointly establish a lithography machine R&D team with Sugon Technology.

Jointly developed the 5th generation lithography machine, which is also the ArFi immersion DUV lithography machine!

If the development of this fifth-generation lithography machine is completed, then Daxia will become the second country in the world that can produce the fifth-generation immersion lithography machine.

It also means that Daxia will have the ability to produce 90nm and 65nm chips. ”

In the face of the words of President Lu of the Xia Academy of Sciences, most of the reporters at the scene were naturally confused.

Without him, the knowledge of the lithography machine is too profound, and people who have not understood semiconductors and lithography machines naturally do not understand what the 5th generation immersion lithography machine is.

The immersion lithography machine is currently the most advanced lithography machine in the world, although it is still essentially an AeF dry lithography machine, and the wavelength of the light source is still 193nm.

However, after the wavelength of the 193nm light source is refracted by water, the wavelength of the light source can be reduced to 134nm, and finally it has a more refined processing ability.

It's like a rough knife edge has become smaller, so the immersion lithography technology is quite magical.

It can be said to be able to turn decay into magic, and it can save countless efforts and money by clever methods.

However, in the face of such a magical technology, Lin Chen is actually not very satisfied, because if the lithography machine can do a good job in the accuracy and processing accuracy of other parts and even the quality of parts.

The equivalent of a 134nm light source wavelength immersion lithography machine is theoretically capable of processing chips with 7nm process technology, but the theory is theory and the reality is practical.

Because the lithography machine is not that you can make the wavelength of the light source 134nm, and then rely on the ability of the 134nm light source wavelength to produce a minimum of 7 nanometer chips.

The lithography machine is a whole, the lithography machine has a total of tens of thousands of precision parts, and the shortcomings of any one part or system will affect the final lithography accuracy.

For example, if you have a laser cutter with an accuracy of 7 nanometers, you can theoretically engrave a work of art with an accuracy of 7 nanometers.

But in fact, when you get the laser scalpel, you will find that the knife is a good knife, but the hand holding the laser cutter keeps shaking and shaking, and you can't control the 7nm engraving accuracy at all.

And what's more troublesome is that you will find that your eyes can't see 7 nanometers clearly, even if you can see 7 nanometers clearly by focusing.

But if you move your hand slightly, you'll be angry and you won't be able to see anything at the 7nm level again, and you'll need to focus repeatedly.

And the biggest headache is that even if your hands don't tremble, your eyes are optimistic, and you will find that your physical constitution is actually not very good.

It is often necessary to take a break after working for a period of time and let the family repair and replace body parts.

As for others, it is nothing to work for several years in a row, and you often have to overhaul and replace parts in a month or two, and this body is really quite weak compared to others.

So even if you have a laser scalpel with a machining accuracy of 7 nanometers, you can't do that kind of engraving accuracy, and a good knife is dusty in your hands.

In this case, this is also the theoretical machining accuracy of 7 nanometers that the immersion lithography machine can achieve.

As a result, Dean Lu of the Xia Academy of Sciences claimed that it could reach 90 nanometers and 65 nanometers of chips.

The reason why it claims to be able to achieve 90 nanometers and 65 nanometers, rather than claiming to be able to achieve up to 7 nanometers.

This is because Daxia's material technology and processing accuracy can only reach 65 nanometers at most, and there is no way to go further.

If you want to break through, you need to meet the standards of Daxia's processing accuracy or material technology and testing technology, and this is why high-end lithography machines are so difficult to break through in the previous life.

Therefore, in addition to the patent barriers of lithography machines, the more important reason is that Daxia material technology and processing accuracy technology and testing technology are not up to standard.
