I add some practice in the real world

Chapter 368 367 It's all black technology!

The more precise the instrument, the more difficult it is to manufacture.

The dry lithography machine conceived by Chen Jue, although its manufacturing principle has long been cleared up by the Internet, and even the blueprints are widely circulated on the Internet, but the lithography machine can really be produced all over the world. There are not many countries where the planes come from.

Because this involves physical precision limitations, the improvement of precision from millimeters to microns to nanometers cannot be polished by hand rubbing precision by senior technicians like in the last century.

It is necessary to use the most sophisticated processing equipment here, and cooperate with experienced technical workers to manufacture parts with high precision.

This kind of skilled workers used to be known as "eighth-level workers".

In the last century, when the annual salary of university professors was only a few hundred yuan, eighth-level workers would start at a hundred yuan when they went out to pick up orders, and they had to be served with good cigarettes and wine when they came out of the mountain, and they had to line up to welcome them when they entered the workshop. The respect must be given in place.

In today's era, although the title of the eighth-level worker has disappeared, it has been replaced by a master who is called a "special technician" in the industry.

And above the special technician level, there is a "chief technician" called a great country craftsman.

Just like Chief Gao, who specializes in assembling and welding rockets in the base, this man can spot weld 10 times without blinking an eye in 60 minutes. In order to invite him out of the mountain, the base just offered him a daily salary of [-]!
You read that right, 60 is his mother's daily salary!
There are not many such super technical talents in the entire human world!

And Chen Jue borrowed the microscopic perspective of [Physical Interference] to make the rice-grain-sized laser lens of the traditional lithography machine to the nanometer level. The technical content here is beyond the reach of a hundred chief technicians like Chief Gao. .

Because the nano-scale laser lens created by Chen Jue has broken through the physical precision that humans currently have.

Even if you want to observe this laser lens, you need to mobilize the electron microscope of the national laboratory.

After all, ordinary electron microscopes have the highest resolution to see objects with a size of 3 nanometers, but the laser lens made by Chen Jue is as small as 1 nanometer in diameter!
It is so difficult to even observe, let alone operate on it.

And the most embarrassing thing is that on the surface of the laser lens with a diameter of 1 nanometer, Chen Jue also used a microscopic perspective to polish a light-gathering section with an arc angle on it. Only in this way can the light source form an atomic diameter (0.1 nanometer) wavelengths of radiation.

Such a coquettish operation that broke through the precision limit several times is equivalent to letting a 90-year-old lady with severe presbyopia + cataracts sew hemorrhoids to someone with a needle and thread. Imitation mass-produced.

Of course, in order to match the nanoscale laser lens, the rest of the parts of this lithography machine have also been greatly modified by Chen Jue.

From the power supply cable to the mechanical bracket for assembling the lens, everything has to be proportionally compressed with the nanoscale laser lens.

In addition, Chen Jue also spent a lot of brain cells to optimize some unreasonable spatial layouts inside the lithography machine under the high-intensity brain calculation.

After all these operations were completed, when a brand new dry lithography machine appeared in front of everyone, everyone including Lin Weiguo widened their eyes in disbelief!
Because the lithography machine made by Chen Jue is too different, not only its volume is nearly ten times smaller than the EUA lithography machine the size of a traditional bus, but even the white outer casing With a distinctive industrial beauty.

"Good... What a beautiful design!" Lin Weiguo took a deep breath and walked in front of the machine. He resisted the shock in his heart, and while trembling, stretched out his hands to touch the smooth outer shell of the machine, and praised in his mouth.

Compared with the few EUA lithography machines developed in the Institute of Optoelectronics, which can be called stupid, black and thick, the white lithography machine in front of me is enough to beat their Optoelectronics Institute for a whole ten streets.

Although it is just the most common cuboid shape, the mirror texture emanating from its surface shows that it is not simple.

"There is no gap in the shell of this machine!"

"My God!"

"What level of machining accuracy is this? I can't even see where its external power port is!"

"And this smooth surface, even with the highest-grit sandpaper, it can't be polished?"

"Is this a lithography machine? How can it be so small?" After looking around the machine, Lin Weiguo and the researchers from the Institute of Optoelectronics talked a lot.

After witnessing Chen Jue's performance comparable to God's creation, the group of them had already fallen into the point where they were almost speechless. They all stared at Chen Jue as if they were begging, and wanted Chen Jue to give them Explain the specific use of this machine.

"I used the operating principle of a dry lithography machine in it, and optimized the useless space by the way."

"Wait to turn on the power and then import your NC program, and by the way, reduce the machining accuracy to the parameters of 0.1 nanometers, and then it can basically run." Chen Jue explained with a smile, and tapped lightly on the case of the machine Knocked.

"It's actually a dry lithography machine? Isn't it an immersion type?"

"If it is based on the principle of dry direct radiation and wants to achieve atomic-level processing precision, then its laser lens must be smaller than water molecules?" Everyone looked at each other, and what they saw in each other's eyes was shock and doubt There is confusion outside.

Not to mention the atomic level, even the processing precision at the molecular level has exceeded the limit of their imagination!
Not to mention integrating such a processing technology comparable to Zenith Star into such a small machine.

In the eyes of everyone, this white photolithography machine looks like it was made by aliens. It is black inside when it is cut!
Even this mirror-smooth shell contains technology they can't understand!
Because when Chen Jue tapped the metal casing of this machine, everyone present did not hear any sound!
Lin Weiguo and Zou Ying, who were walking around the machine, were stunned for a moment after seeing Chen Jue's seemingly meaningless action, and then their complexions changed, showing a bit of confusion in their eyes.

"Why is there no sound?"

"What material is this shell made of?"

They are all engaged in scientific research. Although these people present are not professionally qualified, they are not experts in the field of materials science, but at least they have doctor-level comprehension ability.

In their eyes, this smooth mirror-like machine casing is made of metal materials at first glance.

As long as it is made of metal, it will definitely not be knocked on it like this without an echo!
Because according to the physical characteristics of the metal, the larger the atomic sequence number, the softer the metal and the smaller the echo.The sound of dropping an iron brick on the ground is definitely louder than hitting a gold brick on the ground.

But the problem is, they have all touched the white metal shell in front of them. The texture is definitely not inferior to steel and any known high-strength alloy, but why does its echo completely disappear?
"Boom~Boom~"

Zou Ying's eyes were wide open, a little disbelieving, she picked up her smart watch and touched it lightly a few times.

She found that the metal case had no echo at all, it seemed that only her own watch was vibrating.

"This...isn't it possible?"

"Why is there no sound?"

"Even if you have the processing ability at the atomic level, it is impossible to change the sequence number of the atom itself!" Zou Ying opened her mouth and looked at Chen Jue with doubts and confusion in her eyes.

Even Lin Weiguo frowned and fell into a short thought: "It should be impossible to change the atomic number of metals, right? These materials are all provided by us, and there is no such white metal in the list."

"Unless Comrade Chen Jue can turn stones into gold, break the basic laws of physical operation, and directly manipulate the internal structure of atoms..."

Lin Weiguo first stared at the pure white color on the surface of the machine, and then glanced at the yellow and black anti-radiation signs preserved on the wall of the underground fortification. His face seemed astonished as if he had remembered something, and he trembled all over his body and almost lost his voice. ……I see!"

"This is no ordinary special alloy!"

"It is a single crystal in which several metals are superimposed in a multi-layer structure!"
