Guoxin Carbon-based Integrated Circuit Research Institute.

Chen Shen got out of the car at the door and followed the person leading the way in front of him all the way in the direction of the laboratory.

It was already dark, but the lights were still bright, and through the windows you could see figures in the offices and labs at their desks.

As an outstanding scholar in the field of DNA nanotechnology in China, he led the research team to make great contributions to the application of DNA nanotechnology and integrated circuit production process.

Professor Deng Ziming is not yet 50 years old, with a soldier-like head and a pair of thick-framed glasses on his nose, which gives people the first impression of being crisp and neat.

At this time, his face looked very energetic and excited, as if he had been beaten with chicken blood. After a brief introduction, he led the way in front and spoke to Chen Shen sideways.

"Now that we have prepared for the experiment according to your theory, we can start the first round of experimental verification immediately."

"What experiments are included in the first round?" Chen Shen asked.

Deng Ziming laughed, "There are two experiments in total, both of which are related to DNA nanotechnology. ”

Chen Shen immediately thought, "That should be DNA template printing and assembly, right?" ”

"That's right!" The two took the team behind them, passed through many levels, and put on industrial dust suits to enter the laboratory.

The laboratory is very spacious, which can accommodate a whole small chip production line, and the standards built are completely consistent with the general chip production workshop.

The core team members of the research institute have all been assembled at this time, and everyone is looking at the machines in the experimental area in front of them.

Seeing Chen Shen come in, Academician Liu, the dean of the research institute, walked up with the research team.

Even though everyone was wearing dustproof clothing, and their mouth, eyes, and bodies were tightly wrapped, Academician Liu still recognized Chen Shen in the crowd at first sight, and he stretched out his hands excitedly: "Master Chen, I have admired my name for a long time!" ”

Chen Shen didn't dare to slack off, and also stretched out his hands, and after greeting each other for the first time, the two of them put their eyes on the machine in front of them.

There are two machines in front of you, which look like two large boxes taller than people, with boxy edges, and a transparent panel on the outermost part, which allows you to see part of the operating status inside the machine.

Through the transparent part, you can see that the inside of the machine is loaded with various solutions, which look a lot like witches' potions.

Academician Liu approached with Chen Shen and personally introduced it to the side: "These two machines are the first generation of experimental machines we have developed, the one on the left is the printing machine responsible for the printing and processing of DNA templates, and the one next to it is the assembly machine responsible for the automatic assembly of carbon nanotubes. ”

"We just put wafers into these two machines, and the machines put the wafers into the solution inside, and then the wafers react with those solutions as designed to make the patterns that we designed, or to assemble the carbon nanotubes according to our requirements."

These two machines are all used by Chen Shen's technology, and Academician Liu even gave up his original dimensional self-assembly technology, which is to maintain the unity of the production process.

His self-assembly technology is not highly integrated with the process proposed by Chen Shen.

Deng Ziming walked over and said, "Before receiving your proposal, we never thought that DNA nanotechnology would be applied to the chip production process so quickly. Especially your DNA self-assembly technology, if you change the direction, you may be able to study medical nanorobots, but I don't know if you have that interest. ”

Deng Ziming looked at Chen Shen with a smile, he was quite well-informed in the country, and knew that the young master in front of him would only conduct research that he was interested in, as if he had jumped out of the Five Elements and was no longer in the Three Realms.

Chen Shen shook his head, "DNA self-assembly technology does have some reference role for medical nanorobots, if I have time in the future, maybe I will really work in this direction." ”

DNA self-assembly technology uses DNA strands as a transport tool to deliver carbon nanotubes to a designated location on the chip, which is similar to the idea of medical nanorobots entering the human body to capture viruses in specific cells.

Of course, the two technologies are completely different, but some of the principles may be common.

At this time, the door of the laboratory was opened again, and Chen Shen's eyes turned to a person pushing a cart of wafers and walking slowly.

"Those are the first batch of purpose-built wafers that we received from the fab." Academician Liu introduced.

The foundation of the chip is the wafer, and without the wafer, the chip will have no foundation.

The wafers of carbon-based chips are different from those of silicon-based chips, and now it seems that the fab has successfully completed their task.

The wafers are pushed in front of the inlets of the assembly machine and the printing machine, respectively, and then placed into the two machines by engineers on site according to the protocol.

From the transparent window on the outside, you can see that after the wafer is placed in the machine, it is orderly placed into various solution grooves and soaked, and after a set time is reached, it is changed from one groove to another.

Between these solution transitions, the wafer surface is reacting with these special solutions, and some changes that are invisible to the naked eye are slowly occurring as the design intended......

Unlike the silicon-based production process, which focuses on the physical process, the current carbon-based chip production process focuses more on the biochemical level, as evidenced by the two machines in front of us.

The most important thing in these two machines is the special solution they fill, only these solutions react with the surface of the wafer to process qualified wafers, the machine itself is not important, as long as it maintains stable operation.

Everyone waiting outside the experimental area felt like a big stone hanging in their hearts, this was the first time they had integrated all the steps to conduct an experiment, and it was also the first time that they had conducted a machine experiment.

The previous experiments were carried out manually, if the operation of the two machines is successful, then the first stage of the industrialization of carbon-based chips can be regarded as a success, and these two process steps in the future only need to modify these two machines.

In just two minutes, the wafer sent in was soaked in all the solutions and sent out under the eyes of everyone's expectation.

"Quick, take a look at the assembly of the carbon tube, and put the wafers sent by the printing machine into the ion etching machine." Academician Liu hurriedly commanded.

The people at the scene suddenly became busy, and the stars escorted two wafers like the moon, one of which was sent to the side for manual inspection, and the other was sent to the etching machine for reprocessing.

The test was held on the spot, and the inspectors suddenly turned around after some operation on the workbench, and then the excited voice came: "There is no problem with the assembly of carbon nanotubes, and it is exactly in line with the design expectations!" ”
