Black Technology Live Room

In terms of lithography and etching technology, Huaguo has always been a weakness.

In recent years, the etching machine technology has slowly caught up. Although there is still a gap, we can already see the hope of overtaking in curves.

However, the technology of lithography machines is different. The precision of the lithography machine produced by Shanghai Microelectronics, the most advanced lithography machine manufacturer in China, is 90nm, and the current international standard is 14nm. For example, the current company uses 193nm wavelength lithography. Machine, the limit of accuracy that can be achieved is to make chips with a 14nm process.

But this is not the most advanced lithography machine. The most advanced lithography machine manufacturing technology is EUV (Extreme Ultraviolet) lithography machine from ASML in the Netherlands, which can produce 7nm or even 3nm chips.

From this number, we can clearly see that the huge gap between China and other countries in the lithography machine, and can understand why the country ’s chip technology lags behind.

The reason why domestic lithography machine technology is so backward is that there are multiple reasons.

At that time, when the domestic Shanghai Microelectronics reached a precision of 90nm, the international dominance was only 65nm, and it can be said that the gap was far less than it is now.

Now, there is such a large gap, the root cause is that it has been stagnating.

Why is it stagnant? Because when I saw Hua Guo from abroad, I immediately opened the sales of 65 nm lithography machines to Hua Guo.

The result is that the above support for Shanghai Microelectronics has weakened, coupled with the impact of foreign 65nm lithography machines, it is not profitable, causing people's heart palpitations, and a lot of technical backbones have been lost, which has led to this result today.

I can say that this was a mistake made at the time, and I have been walking, research and development ... outside the entrance allowed ... abandoned research and development ... forbidden sales ... the old way of helpless research and development.

As a result, Huaguo's high-end lithography machines now rely on foreign imports. EUV lithography machines cost up to 100 million euros.

And, crucially, true cutting-edge lithography machines such as EUV are still banned.

The chip industry is completely constrained by others, sometimes just think about it!

Zhang Zhang Zhai rubbed his temples, the most advanced thing of the lithography machine is actually the design idea.

资料 A1 provided him with sufficient information. It can be said that there are only enough people with equipment and materials. It will not be complicated to study this lithography machine based on this multi-G data over time.

"Hoo ..." Zhang Zhai exhaled, changing from a standing position to a sitting position.

"what time is it now?"

"It's 12:34 noon, father, you can consider taking a break, and then start lunch after 16 minutes," A1 replied.

"Two hours?" Zhang Zhai shook her head, smiled at herself, and shook her head.

I was really addicted to learning, unable to extricate myself, time passed so fast, I felt nothing at all.

"Go ahead, then relax." Zhang Zhai stood up, moved her stiff neck, rubbed her eyes, and walked to the workbench.

On the workbench, Aite's body was also placed, but he turned his head back and turned his head back.

Zhang Zhang Di took these bodies, heads, and continued disassembling them, and then disassembled them one by one.

"Crawler robots are not stable enough. The balance is not serious enough. You still need to build personal robots. And intelligent programs do not know how to evolve themselves. They can perfect themselves into this magical logic."

Zhang Zhai muttered while dismantling.

Sometimes, if a person stays too long, he can easily become confounded.

Otherwise, how can there be a mere separation between lunatics and geniuses?

"It's 16 minutes, father, I suggest you go to the cafeteria for lunch now," A1 reminded.

等等 "Wait a minute, I'll fix the problem before I say it." Zhang Zhai took a pencil and a book and didn't know what she was writing or drawing.

"Well, this should be ojbk, try it first."

Zhang Zhai took the paper in his hand and walked to the left.

On the far left side of the room, there is a door similar to an elevator. There is a fingerprint lock on the door. Zhang Zhai looked down at the paper in his hand without raising his head, and put his right index finger on the fingerprint unlocking bar. .

I passed the verification, and the door opened to both sides. Zhang Zhai didn't even see it, so he went in.

When the door was opened, you could see that there was a spacious room inside, but the wall between the two rooms was a little thick, close to one meter.

As soon as I walked into the room, the first feeling was that it suddenly became much hotter.

This room is equipped with a supercomputer, not the superpowerful supercomputer, but it can also be regarded as high-end goods. When Zhang Zhai bought it, it cost more than 80 million.

Zhang Zhangzhai took the paper and entered it into the supercomputer based on the data on the paper.

数据 Some data are too complicated, too cumbersome to calculate by human brain, and waste time.

Zhang Zhai had to use a supercomputer to perform calculations and check calculations.

After a while, Zhang Zhai got the answer he wanted and walked out of that place again.

嗯 "Well, this is the way to do it this time." Zhang Zhai's face showed a little joy.

"Let's get a little guy first, give it a try. Hope not to make another strange one." Zhang Zhai said to herself, and started directly.

拿着 He was holding something, and he was in front of this device for a while, and then he was in front of another device, so busy that his feet were not touching the ground.

似乎 He seems to have completely forgotten, just now A1 reminded him to let him eat.

It is impossible to eat on time. It is impossible to eat on time in this life, and you will not sleep when you are sleeping. You can only do research to maintain your life. It feels better than at home! All of them are talents ~ www.readwn.com ~ They talk to themselves and are nice, I like them very much!

Xun Zheng's so-called non-crazy, not Buddha, no scientist is not crazy when doing key research, it is possible to stay up for days and nights.

Zhang Zhai, at this time, also felt like a demon, and felt like coming up, eating, sleeping, resting, and nothing at all.

Maybe it has something to do with his temperament, but isn't it just this temperament that has brought him so many brilliant achievements?

Otherwise, even if there is a system, such a dull and repetitive life, other people can't stand it.

As the things in Zhang Zhai's hand changed little by little, time passed little by little.

However, the two headlights above the head have always illuminated the laboratory like daylight. Even if the weather outside changes, the laboratory can not feel it at all.

Finally, a decent thing appeared on the workbench.

This time, Zhang Zhai expressed satisfaction with what he designed.

Looking towards the workbench, you can clearly see that this is a humanoid robot, but the shape is still a little funny.

His entire body is connected to the head, like a large capsule, and it looks like a regular oval from the front.

Its feet are short and somewhat thick, and its hands are somewhat long and thin. The most amazing thing is its head. It has only one eye and occupies the large space of the head. At this time, its eyes are Closed.

Finally, its entire body was painted yellow.

Zhang Zhangzhai is really fond of yellow.

This robot image seems familiar?

"Well, starting today, you are Aite II, let me be beaten!" Zhang Zhai was very satisfied with his naming talent, clapped his hands, perfect!
