This method of DNA processing nanographics is called DNA projection nanoprinting, which can also be called DNA template printing.

This method can use DNA as a template to define the substrate pattern.

The principle is to arrange the DNA on the substrate neatly, and then deposit a metal film on it.

The DNA molecule acts as a wax paper, which defines patterns smaller than 10 nanometers on the substrate. Since the metal film is deposited at an angle, the projection of the DNA molecule defines the pattern on the substrate.

Next, the surface of the pattern is etched using a plasma etching machine, and nanometer-sized trenches can be obtained on the substrate.

This is just the right way to bypass the lithography step!

The lithography machine is important in chip production, but its role is actually quite simple.

The role of the lithography machine in chip production is to react with the photoresist on the substrate through the light source, so that the photoresist of the irradiated part deteriorates and is easy to corrode, so as to "draw" the circuit pattern on the photoresist.

The deterioration of the photoresist can then be corroded away, and then the wafer itself can be corroded to form the semiconductor device and its circuit.

In other words, the lithography machine only plays a positioning role, and the real circuit formation still depends on etching!

And now this mapping can be done by DNA templates!

If this technical idea continues, the future preparation of carbon-based chips will follow the way of metaplasia, which is completely soaked out of various solutions.

In addition to carbon nanotubes, nanomaterials such as metals and oxides can also be grown, built, and assembled with DNA tools.

It can be seen that it is not impossible to bubble carbon nanotransistors directly from the solution and then assemble them on the chip.

Moreover, this technology also meets the needs of Chen Shen, and only this new technology that can get rid of lithography machining can meet the production and processing of Oasis series carbon-based chips at present.

The most important thing is that Chen Shen really found the corresponding DNA template printing technology in the processing materials provided by the system!

The technical data of the system is extremely complete, including all the links of carbon-based chip production, among which the production process of this nano pattern manufacturing process not only includes photolithography technology, but also DNA template printing.

This shows that under the systematic calculation, not only can lithography machines be used to make carbon-based chips, but also DNA stencil printing!

The role of the two is indeed the same.

And, as always, the system provides DNA template printing that is several generations higher than the current level, which perfectly solves the application problem of this technology in the production of carbon-based chips.

Even other processes such as carbon nanotube purification, carbon nanotube assembly and arrangement technology, etc., are also several generations ahead of the current generation.

However, none of these technologies are completely beyond the current theoretical foundation, and are more like what the current technological theory has been developed for decades.

Chen Shen carefully studied the two processes of photolithography and DNA template printing, and soon compared the differences between the two methods.

If you use a lithography machine, the biggest advantage is that it is convenient, and you can basically directly use the lithography machine used by the current silicon-based chips.

The use of DNA stencil printing requires a supply chain specifically for this process.

However, one of the biggest advantages of this process is that it is easy to produce, the production environment requirements are at least half lower than that of lithography machines, and there is no need to carry out it in a darkroom.

And it's easier to use this technology to make higher-precision nanopatterns than to upgrade a lithography machine.

At least that's the case for Chen Shen......

At this point, he has figured out the production process of carbon-based chips, so the next step is to take the next step.

For the next few days, Chen Shendu sat in front of the computer, using a brain-computer device to control the computer and write his new technical solutions for carbon-based chips.

As long as this technical solution is born, the theoretical problem of carbon-based chips from development to production will be basically solved, and then there will be the problem of industrialization.

But at that point, it wasn't something he had to think about.

Scientists like him can't play a role in the production of this kind of technology, and this kind of thing has to be carried out by Edges and Corners Technology and Dasheng Industries.

After sleeping in the room for more than a week, and it was late May, Chen Shen walked out of the room with his plan.

Looking at the blue sky outside and feeling the cool sea breeze blowing from the beach at the base under the shade of the trees is very refreshing.

The negative emotions generated by staying in the dormitory before were suddenly carried away by the sea breeze, and if this place had not been blocked, it should also be a refreshing and pleasant scenery mecca.

After wandering aimlessly around the base for a while, Chen Shencai went to Wang Qian's office with the plan in hand.

"Aunt Qian?" Chen Shen knocked on the door, and soon there was an answer sound inside, and he pushed the door in.

Behind the desk, Wang Qian was still crackling on the keyboard in front of her.

Chen Shen couldn't help but feel heartache for that keyboard for a while, and thought about whether to get a set of brain-computer devices for Aunt Qian, so that her keyboard could live a stable second half of her life, save a little office expenses for the base, and improve Aunt Qian's office efficiency.

"You must have made some breakthrough when you came here today?" At this time, Wang Qian suddenly poked her head out from the side of the computer screen to look at him, and immediately saw the hard disk in his hand.

"Of course there is!" Chen Shen smiled, and before he finished speaking, Wang Qian immediately stopped typing on the keyboard, turned off the computer screen, came to the hospitality area, and sat opposite him.

"I guess it's a carbon-based chip?" Wang Qian glanced at the several hard disks in his hand and guessed.

"Uh-huh, yes, take a look." Chen Shen nodded and pushed all the hard disks in front of him in front of Wang Qian.

Wang Qian picked up one of them, glanced at the marks on it, and on it were Chinese characters that he could understand but couldn't understand, and simply gave up getting information from the hard disk, and asked directly: "What breakthrough have you made in this technology?" ”

Chen Shen said: "Judging from the information you gave me, the domestic carbon-based chip technology has reached the preliminary industrial production standard, so I have only made some improvements to these processes. ”

Wang Qian listened carefully, and the voice recorder in her hand had been turned on, recording at any time.

"Next, I need the team from the Yuanmingyuan Vocational Institute to help me do some experiments to verify my ideas, and if there are no problems, I can start researching production equipment and considering industrialization."

This is the end of Chen Shen's words.

Wang Qian thought for a while and asked, "That means your method can also be industrialized?" If you follow your method, what is the highest size of chip that can be produced? ”

For this problem, Chen Shen thought for a while, "Here are some of my production ideas for 14-nanometer carbon-based chips, if there is no problem, it is natural that the production of carbon-based chips with 14-nanometer process can be realized." ”

Wang Qian nodded, although she was a little surprised, but she still secretly wrote down the detail of 14 nanometers.

She naturally knows that if this technology can really be realized, it will be a big change in the chip industry, but in the face of Chen Shen's achievements, she can't raise too much emotion.

Habit is a powerful force......
