Movie black technology

This method of DNA processing nanopatterns is called DNA projection nanoprinting, or DNA template printing.

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

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

The DNA molecule acts as a nano wax paper, so that some patterns smaller than 10 nanometers are defined on the substrate.Since the metal film is deposited at a certain angle, the projection of DNA molecules defines the pattern on the substrate.

Next, a plasma etching machine is used to etch the pattern surface, and then nano-sized trenches can be obtained on the substrate.

This just bypasses the photolithography step!

The lithography machine is very important in chip production, but its role is actually very 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 irradiated part of the photoresist is deteriorated and easily corroded, thereby "drawing" the circuit pattern on the photoresist.

Next, the photoresist in the deteriorated part can be etched away, and then the wafer itself can be etched to form semiconductor devices and their circuits.

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

And now the role of this positioning can be completed by the DNA template!

If we continue to follow this technical idea, the future carbon-based chip preparation will be in the form of biochemistry, which is completely bubbled from various solutions.

Because in addition to carbon nanotubes, nanomaterials like metals and oxides can also be grown, built, and assembled with DNA tools.

This shows that it is not impossible to soak the carbon nano transistor directly from the solution and then assemble it on the chip.

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

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

The technical information of the system is extremely complete, including all the links in the production of carbon-based chips. In this link of manufacturing nano-patterns, the production process includes not only photolithography, but also DNA template printing.

This shows that under the calculation of the system, not only the lithography machine can be used to manufacture carbon-based chips, but also DNA template printing can be used!

The two functions are indeed equivalent.

And as before, the DNA template printing technology provided by the system 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 with other steps such as carbon nanotube purification, carbon nanotube assembly and arrangement technology, etc., the process is also ahead of the current generations.

However, these technologies are not completely beyond the current theoretical basis, and are more like the current technological theory after decades of development.

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

If you use a lithography machine, the biggest advantage is convenience. Basically, you can directly use the lithography machine currently used for silicon-based chips.

The use of DNA template printing requires a special supply chain for this process.

However, one of the biggest advantages of this process is that it is convenient to produce, and the production environment requirements are at least half lower than that of a lithography machine, and it does not need to be carried out in a dark room.

Moreover, it is easier to use this technology to produce higher-precision nano-patterns than to upgrade a lithography machine.

At least for Chen Shen...

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

In the next few days, Chen Shen sat in front of the computer, using his brain-computer device to control the computer, writing about his new technology plan for carbon-based chips.

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

But at that point, it was not something he had to consider.

Scientists like him can't play a role in putting this technology into production. This kind of thing has to be done by Edge Technology and Dasheng Industry.

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

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

The negative emotions generated by staying in the dormitory before were suddenly taken away by the sea breeze. If this place is not sealed off, it should also be a relaxing and pleasant scenic spot.

Wandering aimlessly in the base for a while, feeling relaxed, Chen Shencai took the plan in hand to Wang Qian's office.

"Aunt Qian?" Chen Shen knocked on the door, and there was a reply soon 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 the keyboard for a while, thinking about whether to get a brain-computer device and give it to Aunt Qian, so that her keyboard can live a stable life for the rest of her life and save the base a little office expenses. At the same time, it can also improve Aunt Qian's office efficiency.

"You must have made a breakthrough today?" Wang Qian suddenly looked at him from the side of the computer screen, and immediately saw the hard drive in his hand.

"Of course there is!" Chen Shen smiled. Before he could finish his words, Wang Qian stopped tapping 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 guessed after a glance at the hard drives in his hand.

"Yeah, yes, take a look." Chen Shen nodded, pushing all the hard drives in front of him to Wang Qian.

Wang Qian picked up one of them and glanced at the mark on it. It was a Chinese character that she could understand but could not understand. She gave up getting information from the hard disk and asked directly: "What breakthrough have you made in this technology? ?"

Chen Shen said: "From the information you gave me, the domestic carbon-based chip technology has reached the preliminary industrial production standards, so I just made some improvements to these processes."

Wang Qian listened carefully, and the recording pen in her hand was turned on and was recording at any time.

"Next, I need the team from Yuanmingyuan Vocational College to help me do some experiments to verify my ideas. If there are no problems, I can start to research production equipment and consider industrialization."

The words of Chen Shen end here.

Wang Qian thought for a while and asked: "That means your method can also be industrialized? If you follow your method to produce, what specifications can the highest chip be produced?"

Regarding this question, Chen Shen thought for a while, "There are some of my ideas for the production of 14-nanometer carbon-based chips. If there are no problems, it will naturally be possible to produce carbon-based chips with the 14-nanometer process."

Wang Qian nodded, although she was a little surprised, she secretly wrote down the details 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 results, she can't get too much emotion.

Habit is a powerful force...
