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

Although the manufacturing principle of the dry lithography machine conceived by Chen Du has long been picked up by the major Internet, and even the drawings have been widely circulated on the Internet, there are few countries in the world that can really build a lithography machine.

Because of the physical accuracy limitations, the improvement of accuracy from millimeters to micrometers to nanometers is no longer as it can be polished by the precision of senior technicians alone as in the last century.

It is necessary to use the most sophisticated processing equipment and experienced skilled workers to produce parts with the highest accuracy.

This kind of skilled worker used to be called "eighth-level worker".

In the last century, when the annual salary of university professors was only a few hundred yuan, the eighth-level workers started at 100 yuan when they went out to take orders, and they had to wait for good cigarettes and good wine to invite people out of the mountain.

In today's era, although the title of the eighth-level worker has disappeared, it has been replaced by a big bull known as "special technician" in the industry.

Above the special technician, there is a "chief technician" who is known as a craftsman of a great country.

Just like the senior chief in the base who specializes in assembling and welding rockets, this is a cow who can spot weld 30,000 times without blinking for ten minutes, in order to invite him out of the mountain, the base just gave him a daily salary of 600,000!

You read that right, 600,000 is a fucking daily wage!

There are not many such super technical talents in the entire human world!

Chen Jue borrowed the microscopic perspective of [physical interference] to achieve the nanometer level of the laser lens that was originally the size of a grain of rice from the traditional lithography machine, and the technical content here is beyond the reach of even a hundred chief technicians like Gao Chief.

Because the nanoscale laser lens created by Chen Jue has broken through the physical accuracy that human beings have mastered so far.

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 can only see objects with a maximum resolution of 3 nanometers, but the laser lens made by Chen Jue is as small as only 1 nanometer in diameter!

It's so difficult to even observe, let alone operate on it.

And the most interesting thing is that on the surface of the 1 nanometer diameter laser lens, Chen Jue also used the microscopic perspective to polish the arc-shaped angle of the concentrating section on it, only in this way can the light source form a wavelength ray with atomic diameter (0.1 nanometers) when passing through this laser lens.

Such a sao operation that has broken through the limit of accuracy several times is equivalent to making a 90-year-old lady with severe presbyopia + cataract hold a needle and thread to sew hemorrhoids for people, just thinking about it is enough for chrysanthemums to be tight, not to mention being imitated and mass-produced.

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

From the cables that supply the power to the mechanical mounts that mount the lenses, everything has to be compressed in equal proportions with nanoscale laser lenses.

In addition, Chen Jue also spent a lot of brain cells, and easily optimized some unreasonable space layouts inside the lithography machine under high-intensity brain computing.

When all this was done, a brand-new dry lithography machine appeared in front of everyone, and everyone, including Lin Weiguo, widened their eyes in disbelief!

Because the lithography machine made by Chen Du is too different, not only is its volume nearly ten times smaller than the EUA lithography machine the size of a traditional bus, but even the white exterior case exudes a unique industrial beauty.

"Good...... What a beautiful design! Lin Weiguo took a deep breath and walked to the machine, he endured the shock in his heart, and trembled and reached out to touch the smooth shell outside the machine, while exclaiming in his mouth.

Compared with the EUA lithography machines developed in the optoelectronic institute, which can be called stupid and black, the white lithography machine in front of them is enough to beat them for ten streets in the optoelectronic institute just by its appearance.

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

"There isn't a single crack in the shell of this machine!"

"Oh 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 mesh sandpaper, can't be sanded?"

"This is a lithography machine? How can such a small volume be achieved? After looking around the machine, Lin Weiguo and the researchers at the Institute of Optoelectronics had a lot of discussions.

After witnessing Chen Jie's performance comparable to that of God's creation, the group of them had already fallen into a point where they were almost exhausted, staring at Chen Du one by one, as if they were pleading, wanting Chen Du to explain to them the specific purpose of this machine.

"I used the principle of a dry lithography machine to optimize the useless space."

"Wait for the power on and then import your CNC program, and by the way, reduce the machining accuracy to the parameter of 0.1 nanometers, and you can basically run." Chen Jue explained with a smile on his face, and gently tapped his hand on the case of the machine.

"Dry lithography machine? Not immersion? ”

"If you want to achieve atomic-level processing accuracy based on the principle of dry direct emission, then its laser lens must not be smaller than a water molecule?" Everyone looked at each other, and what they saw from each other's eyes was nothing but shock and confusion.

Not to mention the atomic level, even the processing accuracy at the molecular level has exceeded the limit of the imagination of their group of people!

Not to mention the integration of such a processing technology comparable to the Zenith into such a small machine.

In the eyes of everyone, this white lithography machine looks like it was made by aliens, and when it is cut, it is black inside!

Even this mirror-smooth shell contains technology that they can't understand!

Because when Chen Jue tapped the metal shell of this machine, everyone present didn't hear a single sound!

Lin Weiguo and Zou Ying, who were rubbing around the machine, were stunned for a moment after seeing Chen Jie's seemingly meaningless action, and then their faces changed one by one, and their eyes showed a little confusion.

"How can there be no sound?"

"What kind of material is this shell made of?"

They are all engaged in scientific research, although these people present have the right majors, not to mention the expert level in the field of materials science, but at least they have the ability to understand at the doctoral level.

In their eyes, the shell of the mirror-like machine looks like it is made of metal.

As long as it's made of metal, it will never hit it with your hand like this without an echo!

Because according to the physical properties of the metal, the larger the number of atomic sequences, the softer the metal and the less echo. The sound of taking an iron brick and dropping it on the ground is definitely louder than smashing a gold brick on the ground.

But the problem is, the white metal shell in front of them, they have all touched it with their hands, and the texture is definitely not inferior to steel and any known high-strength alloy, but why has its echo completely disappeared?

"Knock~Knock~"

Zou Ying's eyes widened and she didn't believe in evil, picked up her smart watch and gently bumped it a few times.

She realized that the metal case really didn't respond at all, and it seemed that only her own watch was vibrating.

"This ...... It can't be, right? ”

"How can there be no sound?"

"Even if you have atomic-level processing capabilities, it's impossible to change the sequence number of the atoms themselves!" Zou Ying opened her mouth and looked at Chen Jie's eyes full of doubt and confusion.

Even Lin Weiguo frowned and fell into a short contemplation: "It shouldn't be impossible to change the atomic number of metals, right?" These materials are all provided by us, and this white metal is not on the list at all. ”

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

Lin Weiguo first stared at the white color on the surface of the machine, and then glanced at the yellow-black anti-radiation sign on the wall of this underground fortification, as if he remembered something in shock, and trembled almost in a lost voice: "I...... I know! ”

"This is no ordinary special alloy!"

"It's a single crystal that stacks several metals together in a multi-layered structure!"

Today's first watch, strive to get a second watch
