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

It's a new process.

The purification of carbon nanotubes is not an easy task.

Carbon nanotubes are equivalent to rolling graphene into a cylinder, and depending on the way of alignment, carbon nanotubes will exhibit different properties, some of which are metallic and some are semiconductor.

And chip manufacturing needs to be semiconductor-like.

Previously, the purity of the semiconductor carbon nanotubes they purified was 99.99995%, commonly known as the six 9 purity.

Although this purity is enough for carbon nanotubes to be used in integrated circuits, if they want to be mass-produced for mass production, 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 can be achieved by this new process is 99.99999999%!

Nine nines!

And the more people look at it, the more they feel that this preparation and purification process is too similar to the multiple polymer dispersion and purification processes they are using now, and even the method steps are very similar.

A special dispersant is used for carbon nanotubes, and then the steps of dispersion, purification, filtration, and cleaning are repeated three times......

It can be said that in addition to the use of another more critical special dispersant in this process, the other parts are at least eighty percent 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 above really that magical? ”

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

"A new dispersant, possibly?"

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

It's not plagiarism, there are no patents for such things as process programs, and it is impossible to say that if they do this, others will not be able to follow this line of thought again.

It can only be said that the above process has made many improvements in dispersants, polymer selection, multiple purification processes and polymer separation on the basis of their processes, and the effect of the improvements is also obvious, as evidenced by the three extra 9s after the purity.

Academician Liu in front of him also heard everyone's words, but he just said calmly: "Let's continue to watch first, and when it's over, I will answer everyone's questions." ”

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

Next is the permutation of carbon nanotubes, and from here, Chen Shen uses DNA as a tool.

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

However, everyone present could see at a glance that the process on the screen was the same as the previous one, and it was improved.

However, they can't see what steps have been improved and how much they have changed, after all, this is not their research results, and they are certainly not so familiar.

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

Because the process on the screen starts with the arrangement of carbon nanotubes and continues to the nano-patterns etched on the metal film using the DNA template tool!

The completeness of this process is completely beyond many imaginations.

When they saw this, the conference room exploded, and everyone couldn't help but whisper.

It's 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 it is to mass production, domestic engineers will do their best to solve it!

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

They haven't even made a 90nm process yet......

In a trance, everyone couldn't help but have a feeling of time and space confusion.

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

"Let's keep looking."

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

From here on, the process continues to the packaging, and the process overlaps with the silicon-based chip process to a high degree.

It is basically a 14-nanometer silicon-based chip process, but it has undergone some adaptive transformation, although it has changed, but it is not big.

After watching it, everyone felt like eating popsicles in an air-conditioned room on dog days, and there was a feeling of exhilaration.

They thought back to what had just been on the screen, and the process could be said to be complete.

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

Xie Yu expressed his views with Senior Brother Glasses.

The wafers required for the production of carbon-based chips naturally cannot be exactly the same as those of silicon-based chips, and they also have to undergo certain improvements.

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

"You've read the general information, so if you have any questions, ask now."

Xie Yu was the first to raise his hand.

"Say it." Academician Liu immediately named her.

She stood up, "Which research institute is the result of this process, and how can it be so far ahead of us?" That's weird, isn't it? ”

yes, how can you be so far ahead of us?

The question Xie Yu asked was also the question that others wanted to ask.

As far as they know, they should be at the forefront of domestic research on carbon-based chips, and even they are still researching the 90-nanometer carbon-based chip process, where did the 14-nanometer carbon-based chip process come from?

This feels like Sun Wukong jumped out of the air directly without stones, and what popped out was Sun Wukong after becoming a Buddha.

They didn't think that the information was fake.

Because this information was taken out by Academician Liu, the dean of their 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 character be deceived by a fake profile in his field of expertise?

And they also saw this information with their own eyes, although there are some places where the language is unknown, but it is obviously a need for confidentiality, not that it is not clear.

Academician Liu laughed, and in retrospect, he felt a little dreamy, "This information is ......"

"It has something to do with some of the people here."

"Huh?"

Everyone was stunned all of a sudden, you look at me, I look at you.

Could it be that we have a great god in the middle?

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

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

"Yes." Xie Yu said that this task was given to her at that time, and she was of course impressed by this basic task.

"That information is to be handed over to one person...... Academician Liu said leisurely.
