Movie black technology

On the screen, before 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 cylindrical shape. Depending on how they are aligned, carbon nanotubes will exhibit different characteristics. Some are metallic and some are semiconducting.

What is needed in chip manufacturing is semiconductor properties.

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

Although this purity is sufficient for the use of carbon nanotubes on integrated circuits, if you want to mass-produce applications, this purity needs to be increased by two to three orders of magnitude to insure.

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 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.

They all use a special dispersant for carbon nanotubes, and then repeat the steps of dispersion, purification, filtration, and cleaning 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 not said to be 90%, at least 80% are similar to the process they have developed.

"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 is no specific information on dispersants, but as far as I know, there should be no dispersant that can achieve this effect, right?"

"Maybe it's a new dispersant?"

The researchers in the conference room couldn't help whispering underneath.

This is not plagiarism. There will be no patents for things like craftsmanship. It is impossible to say that they have done this, and other people can no longer follow this idea.

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

Academician Liu in front also heard what everyone said, but he just said calmly: "Let’s keep watching first, and when it’s over, I will answer your questions."

Everyone had to press down on their doubts and continue to look down.

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

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

However, everyone present can tell at a glance that the craftsmanship on the screen is the same as the previous craftsmanship, all of which have been improved.

However, they will not be able to see the specific steps and how much they have changed. After all, this is not the result of their research, and it is certainly not that 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 use DNA template tools to etch nanopatterns on the metal film!

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

When I saw this, the meeting room exploded directly, and everyone couldn't help whispering.

This kind of craft is crazy!

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 an achievable process, no matter how difficult the mass production is, domestic engineers will do their best to solve it!

What's more, it is a carbon-based chip with a 14nm process!

They haven't even worked out the 90nm process yet...

In a trance, everyone couldn't help feeling a sense of chaos in time and space.

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

"Everything is quiet, we continue to look down."

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

From here on, the process of packaging has a high degree of overlap with the process of silicon-based chips.

Basically, they are all 14-nanometer silicon-based chips, but they have undergone some adaptive transformations. Although they have changed, they are not big.

After everyone watched it, it 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, the craft can be said to be very complete.

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

Xie Yu expressed his views with brother glasses.

Naturally, the wafers required for carbon-based chip production cannot be exactly the same as silicon-based chips, and must be improved.

At this time, Academician Liu in front stood up, he clapped his hands and attracted the people who were still discussing.

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

Xie Yu raised his hand first.

"Let's talk." Academician Liu immediately called her name.

She stood up, "Which research institute is the result of this craft, how can it lead us so much? Isn't this too strange?"

Yeah, how can you lead us so much?

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

As far as they know, they should be at the forefront of domestic research on carbon-based chips. Even they are still studying 90-nanometer carbon-based chip technology. Where did this 14-nanometer carbon-based chip technology come from?

It feels like Monkey King just popped out of the air without using stones, and the one who popped out was the Monkey King after becoming a Buddha.

They never thought that this information was fake.

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

It is not an exaggeration to say that he is the first person in the domestic carbon-based chip field.

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

And they also saw this information with their own eyes. Although there are some parts that are unclear, it is obviously necessary for confidentiality, not to explain clearly.

Academician Liu hehe smiled, and in retrospect he felt a little dreamy, "This information..."

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

"what?"

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

Could it be that we have a great god?

Did one person advance the process of carbon-based chips to this point?

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

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

"That information is for one person..." Academician Liu said leisurely.
