What is the most abundant thing in the desert?

The answer seems obvious, it's sand.

Then another question arises. Since there is so much sand in the desert, why does no one use 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 gain outweighs the loss.

However, the location where Zhang Zhai is now is the Gobi, and not far away is the desert.

However, when building roads, desert sand 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 use as building materials.

The reasons can be roughly attributed to two points. One is because 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 because the sand in the desert is not entirely fine.

A large part of sand is fine dust, and the dust content is very high.

Zhang Zhai stepped on the Gobi Desert and looked at the desert in the distance, inexplicably thinking of the stories he had read.

It said that sand is used to produce new chips and solar panels combined into a new material, and then this new material is used to build the entire city. And because these new materials also have chip functions, the entire city is completely connected in series.

into a very large computer community.

This idea was simply a genius idea, and Zhang Zhai was deeply impressed.

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 using a handful of sand (you can download it on Baidu, it’s quite interesting).

The origin of this joke is that computer CPUs are 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 it’s wool!

It's just whimsical, okay?

Is this something one person can do?

The reason why CPUs are so expensive is not because of the technical difficulty, but basically has nothing to do with their raw materials.

The entire production process is divided into several steps: selecting raw material sand (quartz), purifying it into silicon ingots, wafers, photolithography, etching, ion implantation, metal deposition, metal layers, interconnection, wafer testing and cutting, core packaging, etc.

The process, in which purification, photolithography, and etching are all difficult and difficult.

Building a CPU factory is no longer a simple matter of money. Photolithography and etching have always been China's weakness. High-precision photolithography machines and etching machines are also banned and restricted by developed countries.

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

Zhang Zhai expressed doubts.

"This kind of idea is simply unreasonable. 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, if you want to do it, the feasibility is too low.

However, it can also be considered as an alternative and work in this direction.

After all, if we can do it, can we break the foreign technology monopoly?"

As Zhang Zhai spoke, he couldn't help laughing.

"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 combine it with solar energy.

board combination to really develop this new type of material.”

"So, my next research should be to study etching and lithography technology while continuing to study intelligent robots. The former can provide the prerequisite for new material production and can bring changes to many aspects. The latter was established by Zhai Cheng

The premise is also the premise of intelligence." Zhang Zhai lowered his head and looked at the stones and gravel under his feet.

"However, you have to eat the food one bite at a time, don't be in a hurry." Zhang Zhai sighed.

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

I encouraged myself and felt much better.

After thinking about this clearly, Zhang Zhai no longer wanted to wander around anymore, turned around and walked back.

"Crack!"

Zhang Zhai felt that he had stepped on something. When he lowered his head, he saw that it was a Salix tree.

"Who said that there is no grass growing in the Gobi Desert? No matter how desolate the place is, there are still some stubborn things."

Zhang Zhai smiled and said.

He paused, raised his feet, bent down, and lifted up the Salix tree that had been trampled into the sand.

No reason, just because sometimes, staying on the edge of the desert, in the Gobi Desert, he also felt that he was like a salix.

"However, my Salix tree is destined to grow into a big tree." Zhang Zhai looked at the Salix tree and muttered to himself in a low voice, so small that only he could hear it.

"Ahem..."

During the day, the sky was filled with yellow sand on the edge of the desert. 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, Zhang Zhai simply tidied up, then opened the entrance to 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 cut into pieces by him.

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

It's simply too horrible to look at!

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

Ignoring Aite, who had been torn into pieces, Zhang Zhai called out A1.

"A1, call me the most advanced manufacturing technology of photolithography and etching machines."

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

"Confirm the authorization." Zhang Zhai nodded and said, "But be careful not to 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?"

"Bring it out." Zhang Zhai nodded, and A1 brought out two files with two G's each.

Zhang Zhai looked through it briefly and showed a satisfied smile. It was indeed the "most advanced" information.

The poor country of the United States did not know the important technology of photolithography and etching machines, but it was so easily taken over by Zhang Zhai.

The so-called most advanced technology is all confidential.

The most advanced etching and photolithography 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 and got these two documents back.

Zhang Zhai opened these 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 had not been exposed to this cutting-edge technology of photolithography before and did not understand many professional terms.

However, he also has a way.

"A1, mark out all the proper nouns in the data and explain them in detail."

"Yes, father."

Now, any college student majoring in engineering or science can read without any difficulty. Zhang Zhai started reading with great satisfaction.

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