Rebirth: I carry a desktop computer inside me

Carbon-based chips are a huge and cutting-edge topic.

Jiang Cheng roughly calculated that at present, there are at least several major difficulties that restrict the R & D team to continue to move forward.

The first place is the purification of carbon.

In the field of microelectronics, purity is a very important thing, in chemistry class, everyone has learned about the periodic table, but the reality is that it is difficult to find an element of complete purity.

Even if it is water, the water you usually drink has a lot of impurities such as minerals, even if it is ultrapure water for chip production, it is only a very small range of internal impurities, which does not mean that there are no impurities.

The second is the manufacture of carbon nanotubes, the manufacture of conductive switches, the mass production of carbon-based wafers, and so on.

In addition, for carbon-based chips, P-type doping and N-type doping are more complex.

Of course, this is for the current scientific community, Jiang Cheng has been conducting simulation scientific research through the virtual laboratory of supercomputing over the years, and has achieved great results.

Among them, the most important thing is that Jiang Cheng has developed a method for preparing high-purity carbon nanotubes by dispersion centrifugation, and has also studied P, N-doped elements, and achieved good results.

These two big breakthroughs made his R&D team progress very fast.

The whole team has a total of 52 people, including 30 engineers from Maple Fire Group and 22 researchers from Mizuki University.

Jiang Cheng as the leader of the research group, there are two deputy team leaders, one of which is Tang Jianshi, a professor of microelectronics at Mizuki University, who previously studied memristor chips with Jiang Cheng and changed from an assistant professor to a full professor, so when he knew that Jiang Cheng continued to engage in cutting-edge technology research, he specially applied to join.

The other is Ding Chengjun of Fenghuo Group Company, the general manager of the Shenlong chip business unit.

He is a technical manager, and outside of management, he prefers to research.

To this end, Jiang Cheng put the deputy general manager of his business unit in charge of daily operations temporarily, and transferred Ding Chengjun to focus on carbon-based chips.

"Jiang Dong, in terms of material preparation, our improved dispersion centrifugation method has a very good effect, the cost has been controlled, and the conditions for mass production are also available." Ding Chengjun reported. "The carbon nanotubes that are now mass-produced have a purity of more than 99.9999%."

Jiang Cheng was a little relieved, for this mass production of the word, the energy to spend was very large.

Many things can only be prepared in small quantities and stored in the laboratory.

But Jiang Cheng is different, he came to achieve the goal of mass production from the beginning, he can't commercialize, why did he engage in cooperative research and development with schools?

This is the profit-seeking nature of capital.

Jiang Chengyi clapped his hands, "Okay, the first step of the Long March, we can announce that we have entered the second stage, that is, to manufacture carbon-based chips." "

After the completion of the second stage, it is the last stage, the circuit on the carbon nanotube is integrated, this process can be done without a lithography machine, because the PN structure of carbon nanotubes is not the same as that of silicon-based chips."

Tang Jianshi smiled on the side, "Our research is not easy, but if it really breaks through, it is also a technology that leads the world, when all the advantages based on silicon-based chips will collapse completely, and Jiang Dong's Maple Fire will become a giant company comparable to Intel."

Jiang Cheng also has this expectation, "So it depends on the joint efforts of everyone, and researchers are needed later, we continue to add, one hundred, two hundred, or even a thousand, it is not a word, I am determined to make carbon-based chips." "

As for the money?

Not to mention hundreds of millions, even tens of billions, it is also necessary to develop it.

Of course, due to Jiang Cheng's preliminary research, they saved a lot of heart, dispersed centrifugation, completed the experiment under Jiang Cheng's guidance, and successfully achieved mass production.

"This is really a great project, I hope to research it in my lifetime, maybe we can rely on this to win the highest science and technology award." Compared with Ding Chengjun, Tang Jianshi is much more emotional, and devoting himself to this research makes him full of energy every day.

Ding Chengjun just smiled indifferently, "Jiang Dong, what do you think we use as a substrate material is better?" "

Silicon-based chips use high-purity monocrystalline silicon wafers, and a silicon oxide layer is formed on the silicon wafer, which can be etched on it.

But carbon-based chips are different.

Using a silicon oxide layer as a substrate material is also possible, but this is equivalent to being able to use the silicon wafers currently produced.

But whether this material is the best, Ding Chengjun is not good.

No real experiments have been carried out yet.

"First choose 2 aspects, one is silicon carbide, the other is silicon oxide, for now, you can first take silicon wafers for experiments, see how to display carbon nanotubes." Jiang Cheng reminded, "My suggestion is to keep the made carbon nanotubes in a solution, then just put the wafer in water, and use a watermark-like method to cover the carbon nanotubes regularly."

Ding Chengjun listened carefully and nodded uncontrollably.

In this regard, Jiang Cheng's scientific research ideas and ideas are all places he wants to learn.

Because every experiment will prove that Jiang Cheng's thinking direction is right, at least a very good direction.

So far, Jiang Cheng has not put forward any contrary or inconclusive proposals.

It makes people feel that Jiang Chengcheng is a person with a sense of scientific research.

But Ding Chengjun understood that Jiang Cheng's basic knowledge was too solid, his knowledge was too broad and deep, and these accumulations were the key factors for his scientific research to be unfavorable.

(Jiang Cheng: Well, that's what my plugin thinks too.)

"Okay, then we'll go in this direction next." Ding Chengjun glanced at Tang Jianshi and nodded in reply.

Subsequently, Jiang Cheng left the laboratory and looked at the scientific research team of the Department of Computer Science, they are the team of artificial intelligence special class, Hao Yongjun, Zhang Meng, and Yao Shunyu and others, the research direction is the direction of biochips, that is, through the pulse neural network model, the corresponding circuit logic and design specifications for biochips are proposed.

This is also a completely new direction.

Two researches, because Jiang Cheng had money in his hands, Mizuki University engaged in a joint scientific research project, and spent a large amount of money without blinking his eyes.

Of course, what Hao Yongjun is currently researching is only a very early part, just a small incision.

The money used is not much for the time being.

Unlike the carbon-based chip project, it really costs money like flowing water, to prepare graphite, and then to prepare carbon nanotubes, etc., all of which require money and precious materials.

Jiang Cheng simply looked at the progress of the group, and he was not satisfied, but just let them use their imagination to see if they could have a good design.

Nature guidance will also guide you.

Afterwards, Zhang Meng stopped Jiang Cheng.

"Master, Xu Siyuan came back during the New Year."

Well? Jiang Cheng's brows frowned slightly.

"I went out of my way to meet him, and he gave me a contact number and a new buckle number." Zhang Meng continued, "He said that his buckle was stolen and could not be recovered, so he could not contact others.

The corners of Jiang Cheng's mouth lifted slightly, "Is that so?"

Zhang Meng chuckled, "Who knows."

"Do you believe it?"
