Black Technology Live Room

What is the most abundant thing in the desert?

The answer seems obvious, sand.

Then another question arises, since there is so much sand in the desert, why no one uses the sand in the desert to build houses? You know, sand is the main building material.

Some people say that it is because the transportation cost is too high and the loss outweighs the gain.

However, Zhang Zhai's current location is the Gobi, and the desert is not far away.

However, when building roads, the sand from the desert was not used. Instead, sand had to be transported from other places.

what is the reason?

The fundamental reason is not the transportation cost, but because the sand in the desert is not suitable for building materials.

The reason can be attributed to two points. One is that the sand in the desert is too fine, and the sand used for construction is basically coarse sand fished out of the river. The other is that the sand in the desert is not entirely Sand, a large part of it is fine dust with a very high dust content.

Zhang Zhai stepped on the Gobi Desert, looked at the desert in the distance, and inexplicably remembered the jokes he had read.

It says that a new material is formed by using sand to produce a new type of chip and a solar panel, and then use this new type of material to build the entire city. Because these new materials also have the function of chips, the entire city is completely connected in series. into a super-large computer cluster.

This idea is simply a genius-like idea, which made Zhang Zhai very profound.

So, at this moment, looking at the vast desert, Zhang Zhai thought of this method.

Is this method feasible?

This reminded Zhang Zhai of another joke: a simple way to make a cpu with a handful of sand (you can go to Baidu to download it, it’s quite interesting.)

The origin of this stalk is because the computer cpu is made of sand (quartz).

Therefore, people often ask, why is the CPU so expensive when sand is so cheap?

It seems that it is entirely possible to use sand to make a chip!

Maybe a yarn!

It's just whimsical, okay?

Is this something a person can do?

The reason why cpu is so expensive is not because of technical difficulty, and basically has nothing to do with his raw materials.

The whole production process is divided into several steps: selecting raw material sand (quartz), purifying silicon ingots, wafers, photolithography, etching, ion implantation, metal deposition, metal layers, interconnection, wafer testing and cutting, core packaging, etc. In the process, purification, lithography, and etching are all difficult points.

It is no longer a matter of simple money to build a cpu factory. Photolithography and etching have always been Huaguo's weakness. High-precision photolithography machines and etching machines are still banned and restricted by developed countries.

Moreover, can the sand in the desert really be used to make CPUs?

Zhang Di expressed doubts.

"This kind of idea is simply unconstrained. Although it seems possible to realize it, it is too far away from reality, unless I can directly obtain the production method of this similar material in the next stage of materials.

Otherwise, the feasibility of doing it is too low.

However, it can also be used as an alternative to work in this direction.

After all, if it can be done, can it be regarded as breaking the foreign technology monopoly? "

Zhang Zhai couldn't help laughing while talking.

"If I really follow this idea, first of all, I will break the constraints of photolithography and etching technology, and develop a higher-precision photolithography and etching machine, at least to catch up with other countries, and then consider how to integrate it with solar energy. Plate combination, really developed this new material."

"So, my next research should be to continue to study intelligent robots while studying etching and lithography technology. The former can provide the premise for the production of new materials and can bring changes to many aspects. The latter is established by Zhai Cheng. The premise is also the premise of intelligence." Zhang Zhai lowered his head and looked at the rocks and gravel under his feet.

"However, the meal needs to be eaten bite by bite, so don't be in a hurry." Zhang Zhai sighed.

"The revolution has not yet succeeded, comrades still need to work hard!"

I cheered myself up and felt much more at ease.

After thinking about this clearly, Zhang Zhai lost the intention to continue wandering around, turned his head, and walked back.

"Crack!"

Zhang Di felt that he had stepped on something, and looked down, it turned out to be a salix plant.

"Who said that on the Gobi Desert, not a single blade of grass grows, and even in a barren place, there are some stubborn things"

Zhang Di smiled and said.

He paused, raised his feet, bent down, and helped the willow plant that had been stepped into the sand to stand up again.

Not for any reason, just because, sometimes, when he is on the edge of the desert, on the Gobi Desert, he also feels that he is like a salix.

"However, my salix is ​​destined to grow into a big tree." Looking at the salix, Zhang Zhai muttered to himself in a low voice that only he could hear.

"Ahem..."

During the day, on the edge of the desert, the sky was full of yellow sand. After only half an hour out, Zhang Zhai's whole body seemed to be dyed with a layer of muddy yellow dye.

After returning to the camp, after cleaning up briefly, Zhang Zhai opened the entrance of the underground laboratory and got in.

In the underground laboratory, it was still as quiet as ever.

Zhang Zhai glanced at a figure on the workbench, it was Aite who had been chopped into pieces by him.

It already separates the chassis from the upper body, the upper body from the arms and neck, and the neck from the head.

Simply, appalling!

Who told him to pour hot water on Zhang Zhai's crotch? If it's cold water, Zhang Di can bear it, but hot water? Even men can't stand it!

Regardless of Aite who had already been dismembered, Zhang Zhai called A1 out.

"A1, call me the most advanced manufacturing technology of lithography machine etching machine."

"Father, are you sure you want the most advanced manufacturing technology? If you are sure, please authorize." A1 asked back.

"Definitely authorize." Zhang Zhai nodded and said, "But be careful, don't leave any traces."

"I understand." A1 nodded in agreement.

About a minute later, "Father, the information you want has been downloaded, do you want to call it up directly?"

"Call it out." Zhang Zhai nodded, and A1 called out the two files with two G's.

Zhang Zhai briefly looked through it, showing a satisfied smile. It really is the "most advanced" information.

Poor Miguo still doesn't know about the important technology of lithography and etching machines, so Zhang Zhai took it over so easily.

The so-called most advanced technologies are all kept secret.

The most advanced etching and lithography technology is also the lifeblood of the United States.

The authorization requested by A1 just now is actually an intrusion authorization.

After Zhang Zhai authorized it, A1 went directly to the United States for a tour, and took these two documents back.

Zhang Zhai opened the two documents and began to read them.

There are pictures, text, data, and even videos, which can be described as extremely detailed information.

However, Zhang Zhai has never been in contact with this cutting-edge technology of photolithography and etching before, and there are many professional terms that he does not understand.

However, he also has a way.

"A1, mark all the proper nouns in the materials, and mark them with detailed explanations."

"Yes, father."

Now it’s all right, any college student majoring in engineering or science can read without barriers, Zhang Zhai looked at it very satisfied.

His reading speed is fast, but not his fastest, only half the speed.

While looking at these materials, he understood, and at the same time, he was thinking about where there was still room for improvement.

The idea of ​​making a new type of chip out of sand in this piece is borrowed from the book review of Book Friends: Empty Nest Elders Post-80s.

Finally, ask for a recommendation ticket.
