Chapter 98: Sand and new materials

最多 What is the most thing in the desert?
The answer seems obvious, it's sand.
Then another problem appeared. Since there is so much sand in the desert, why no one uses sand in the desert to build a house? You know, sand is the main building material.
Some say it is because the transportation cost is too high, and the gains are outweighed.
But Zhang Di is now in Gobi, not far from the desert.
But when the road was built, the sand of the desert was not used, but the sand was transported from other places.
what is the reason?
The root cause is not a matter of 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 from the river. The other is that the sand in the desert is not exactly A large part of the sand is fine dust, and the dust content is very high.
Zhang Zhangzhai stepped on the Gobi Beach and looked at the desert in the distance, remembering inexplicably the snippet he had seen.
It said that using sand to produce new chips and solar panels combined into a new material, and then using this new material 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.
想法 This idea is a genius-like idea, which makes Zhang Zhai very deep.
So, at this moment, looking at this large desert, Zhang Zhai thought of this method.
Is this method feasible?
This reminds Zhang Zhai of another paragraph: an easy way to make a cpu with a handful of sand (you can go to Baidu, it's very interesting.)
The source of this stem is because the computer CPU is made of sand (quartz).
So people often ask why sand is so cheap, why is cpu so expensive?
It seems that it is completely possible to make a chip from sand!
May be a woolen yarn!
Is it whimsical at all?
Is this something one can do?
Why does cpu sell so expensive? It is not because of technical difficulty, and it has nothing to do with his raw materials.
The entire manufacturing 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, interconnections, wafer testing and cutting, and core packaging. The process, including purification, lithography, and etching are all difficult points.
If you want to build a cpu factory, it is no longer a simple matter of money. Lithographic etching has always been the weak point of China. High-precision lithography machines and etching machines have also been banned and restricted by developed countries.
And, can sand in the desert really be used to make cpu?
Zhang Zhai expressed doubt.
"This idea is nothing short of imaginary. 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 the material.
Otherwise, the feasibility is too low.
However, it can also be used as an alternative to work in this direction.
After all, if it can be done, it can be considered to break the foreign technology monopoly? "
Zhang Zhai was talking and he couldn't help laughing.
"If you really follow this idea, first of all, I will break the restrictions on photolithography and etching technology and develop a higher-precision photolithography etcher, at least to catch up with other countries, and then consider how to combine it with solar energy Board combination, really developing this new material. "
"So, my next research should be, while studying the etching and lithography technology, continue to study intelligent robots. The former can provide the premise of 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 her head and looked at the stones and gravels under her feet.
不过 "However, rice should be eaten bit by bit. Don't worry." Zhang Zhai sighed.
"The revolution has not yet succeeded, comrades still need to work hard!"
I encouraged myself and felt more comfortable.
I thought about it, Zhang Zhai didn't have the thought of hanging around anymore. She turned her head and walked back.
"Click!"
Zhang Zhai felt what he had stepped on, and looked down, it turned out to be a willow.
"Who says that on the Gobi Desert, where grass is not alive, and even barren places, there is something stubborn."
Zhang Zhang Zhai smiled and said.
He paused, lifted his feet, bent down, lifted the willow that had been stepped into the sand, and lifted it up again.
I do n’t know why, just because, sometimes, by the desert side, on the Gobi Beach, he also feels that he is like a willow.
"However, my sand willow is destined to grow into a big tree." Zhang Zhai looked at the sand willow, whispered, with a very small voice that only he could hear, said to himself.
"Ahem ..."
During the day, near the desert, the yellow sand was full of sky. Just half an hour out, Zhang Zhai's body was covered with muddy dye.
I went back to the camp and simply cleaned up. Zhang Zhai opened the entrance to the underground laboratory and got in.
The underground laboratory is as quiet as ever.
Zhang Zhai glanced at a figure on the workbench, which was Aite who had been unloaded by him.
It is already separated from the chassis and upper body, the upper body from the arm and neck, and the neck from the head.
It's simply terrible!
Who asked it to pour hot water on Zhang Zhai's crotch? If it was cold water, Zhang Zhai could still stand it, but hot water? No man can bear it!
I didn't care about Aite, who had been unloaded eight pieces, Zhang Zhai called out A1.
"A1, bring me the most advanced manufacturing technology for lithography and etching machines."
"Father, are you sure you want the most advanced manufacturing technology? Yes, please authorize." A1 asked in return.
"Determine the authority ~ EbookFREE.me ~ Zhang Zhai nodded and said," But be careful, don't leave traces. "
"I understand." A1 nodded and agreed.
About a minute later, "Father, the information you want has been downloaded. Do you want to call it directly?"
"Take it out." Zhang Zhai nodded, and A1 transferred out two files with two Gs.
Zhang Zhangzhai glanced briefly and showed a satisfied smile, which turned out to be "the most advanced" information.
Poor Mi Guo didn't know the important technology of the lithography machine and etching machine, so it was so easy that Zhang Zhai took it.
The so-called most advanced technologies are all confidential.
The most advanced etching and lithography technology is the same thing in the country.
The authorization requested by A1 just now is actually an intrusion authorization.
After Zhang Zhang's authorization, A1 went directly to the country to take a turn, and took these two materials back.
Zhang Zhang Di opened these two materials and began to look up.
There are pictures, text, data, and even videos, which are detailed and extreme information.
However, Zhang Zhai has not been exposed to this cutting-edge technology of photolithographic etching before, and many professional terms are unknown.
Alas, he also has a solution.
"A1, mark out the proper nouns in the materials, and mark them for detailed explanation."
"Yes, father."
This is all right. Any college or science student who comes here will be able to read without obstacles. Zhang Zhai looked at it with satisfaction.
He reads very fast, but it's not even his fastest speed, only half of it.
While looking at these materials and comprehending, he is still thinking about where, there is still the possibility of improvement.
