Movie black technology

On the screen, in front of them is the first process of carbon-based chips - carbon nanotube purification.

This is a new craft.

The purification of carbon nanotubes is not an easy task.

Carbon nanotubes are equivalent to rolling graphene into a cylinder. According to different alignment methods, carbon nanotubes will show different characteristics, some are metallic, and some are semiconducting.

And what chip manufacturing needs is semiconductor nature.

The purity of the semiconducting carbon nanotubes they purified before is 99.99995%, commonly known as six 9 purity.

Although this purity is enough for carbon nanotubes to be used in integrated circuits, if mass production is to be applied, this purity needs to be increased by two to three orders of magnitude to be safe.

And judging from the description of the new process on the screen, the purity that this new process can achieve is 99.9999999%!

Nine nines!

And the more people looked at it, the more they felt that this preparation and purification process was too similar to the multiple polymer dispersion and purification process they are using now, and even the method steps were very similar.

They all use a special dispersant for carbon nanotubes, and then repeat the steps of dispersion, purification, suction filtration, and cleaning three times...

It can be said that apart from the use of another more critical special dispersant in this process, not to mention 90%, at least 80% of the other parts are similar to the process they have developed so far.

"This... how do I feel that this process is similar to ours? Is the dispersant described in the plan really so magical?"

"I don't know, there's no specific information on dispersants, but as far as I know, there shouldn't be a dispersant that can achieve this effect, right?"

"Maybe a new dispersant?"

The researchers in the conference room couldn't help but whisper.

This is not plagiarism. There will be no patents for such things as technological procedures. It is impossible to say that if they do this, other people can't follow this line of thinking.

It can only be said that the above process has made many improvements in terms of dispersant, polymer selection, multiple purification processes and polymer separation on the basis of their process, and the effect of the improvement is still obvious. A 9 is proof.

Academician Liu in front also heard what everyone said, but he just said calmly: "Go ahead and watch it first, and I will answer everyone's questions after the show is over."

Everyone had no choice but to suppress the doubts in their hearts and continue to look down.

Next is the arrangement and combination of carbon nanotubes. From here, Chen Shen used DNA as a tool.

This direction is similar to the research direction of another Yuanmingyuan Vocational College professor, but it is different from the research direction of Academician Liu's team.

However, everyone present could tell at a glance that the craftsmanship on the screen was the same as the previous one, and it had all been improved.

However, what steps have been improved and how much has been changed, they will not be able to see it. After all, this is not their research result, and they must not be so familiar with it.

But judging from the description of the effect, it is obviously far superior to the original effect.

Because the process on the screen starts from the arrangement of carbon nanotubes and continues to use DNA template tools to etch nano-patterns on the metal film!

The integrity of this craft is completely beyond everyone's imagination.

When seeing this, the meeting room exploded, and everyone couldn't help talking in a low voice.

The craftsmanship is simply insane!

If this process can really be realized, there is no doubt that the industrial mass production of carbon-based chips will be tomorrow.

As long as there is a process that can be realized, no matter how difficult mass production is, domestic engineers will do their best to solve it!

And this is a carbon-based chip with a 14nm process!

They haven't even come up with a 90nm process yet...

In a trance, everyone couldn't help feeling a space-time disorder.

Academician Liu still looked calm, or he had already calmed down from his surprise.

"Everyone be quiet, let's continue to look down."

The next process is relatively simple, because from this step, the carbon-based chip enters the etching step.

From here, until the encapsulation process, there is a high degree of coincidence with the process of silicon-based chips.

Basically, they are all 14nm silicon-based chip technology, but some adaptive transformations have been carried out. Although there have been some changes, they are not big.

After watching it, everyone felt like eating popsicles in an air-conditioned room during the dog days, with a refreshing feeling.

They recalled the content on the screen just now, and the craftsmanship can be said to be very complete.

"However, there are still some places that are missing, such as the production of new wafers."

Xie Yu expresses his views with Brother Glasses.

Naturally, the wafers required for the production of carbon-based chips cannot be exactly the same as those for silicon-based chips, and must undergo certain improvements.

At this time, Academician Liu stood up in front, and he clapped his hands to attract everyone who was still discussing.

"Everyone has read the general information. If you have any questions, please ask them now."

Xie Yu was the first to raise his hand.

"Go ahead." Academician Liu immediately called her name.

She stood up, "Which research institute is this technology the result of, how could it be so far ahead of us? Isn't this too strange?"

Yes, how come you are so far ahead of us?

The question Xie Yu asked was also a question that other people wanted to ask.

As far as they know, they should be at the forefront of research on carbon-based chips in China. Even they are still researching the 90nm carbon-based chip process. Where did the 14nm carbon-based chip process come from?

This feeling is that Monkey King jumped out of the air without using stones, and what jumped out was Monkey King after becoming a Buddha.

They never thought that this information was fake.

Because this information was produced by Academician Liu, the dean of their research institute!

It is not an exaggeration to say that he is the first person in the field of carbon-based chips in China.

How could such a person be deceived by a fake information in his field of expertise?

And they also read this document with their own eyes. Although there are some places that are unclear, it is obviously necessary for confidentiality, and it is not unclear.

Academician Liu chuckled, and felt a little dreamy in retrospect, "This information..."

"Speaking of it, it has something to do with some of the people here."

"ha?"

Everyone was dumbfounded, you look at me, I look at you.

Could it be that a great god has emerged among us?

One person has advanced the technology of carbon-based chips to this point?

Academician Liu continued: "A few weeks ago, I asked a few of you to compile a study material and experimental data about carbon-based chips, do you remember?"

"Remember." Xie Yu said, when this task was given to her, she was of course impressed by this basic task.

"That document is to be handed over to someone..." Academician Liu said leisurely.
