Madam, As Much As You Want

"My next goal is the research direction that our country has been focusing on!

Chen Chong looked at the expectant crowd and said word by word:

"Carbon-based chips!

"This is the biggest puzzle I have to solve next! 35

"Although the research and development of carbon-based chips has always been a problem for Donggu...

"But this technology, with me, has made a major breakthrough!"

"Not just a breakthrough in material technology, but a holistic breakthrough related to carbon-based chips!""

Chen Chong's words surprised the people present.

A reporter from the Central Media asked carefully:

"Mr. Chen, the domestic technology media has always had a saying!"

"By taking the road of carbon-based chips, you can completely avoid the limitations of foreign high-precision lithography machines!""

"What do you think about this issue?

When Chen Chong heard this question, he was speechless and said directly:

"That's a good question!"

"It's a common misunderstanding among people in the tech circle over the years!""

"The research and development of carbon-based chips is indeed a very important breakthrough for Dongguo.""

"But what I want to say is that even with carbon-based chips, it is still difficult for Dongguo to get rid of the need for lithography machines.

"The application of this technology will still be limited by high-precision lithography machines. 35

"The world has been using silicon-based chips now. Years

“The fabrication process of silicon-based chips has long been proficient under the precipitation of many years of industrial systems. 35

"But because it needs a lithography machine in the production process, Dongguo's lithography machine technology is currently the most common and can only achieve 28 nanometers, and laboratory-level lithography machines can only reach 22 nanometers." "

"Foreign lithography machines can achieve 14 nanometers, or even more precise.

"Dongguo is obviously slightly inferior to the accuracy of the lithography machine."

"If you want to improve the accuracy, you can only introduce foreign lithography machines for production!"

Having said that, Chen Chong paused, adjusted the volume of the microphone, and said hungry:

"Of course, the advanced level of foreign countries can reach 5 nanometers, and this is not all because of the lithography machine!

"But it is undeniable that the lithography machine is a key link in the chip manufacturing technology!

"It is precisely because of the backwardness of lithography machine technology that Dongguo is usually stuck in the state of being stuck in chip production."

"So, the fundamental problem that the chip technology has been stuck in the neck is: whether the lithography machine technology can be properly solved.

"Since Dongguo's carbon-based chip was successfully developed, there have been endless rumors about the performance of carbon-based chips.

"Many media have claimed that the production of Dongguo carbon-based chips can be achieved without the aid of a lithography machine.

"You know, this kind of idea means that Dongguo has made a big step forward in the chip manufacturing process, and can directly bypass the lithography machine technology to achieve overtaking in corners.

Chen Chong's tone suddenly increased.

"What I'm saying is that this statement is ridiculous!"

"A correct understanding of the development of carbon-based chips to achieve cornering overtaking...

"It is carbon-based chip technology that is more advanced than silicon-based chips.

"With a relatively low-level lithography machine, high-level chips can also be produced.

"In this sense, we will not be stuck in the neck by high-grade lithography machines in chip manufacturing."

"This is the correct understanding of corner overtaking!"

“Instead of developing carbon-based chips, there is really no need for a lithography machine!’95

The advantage of carbon-based chips compared to silicon-based chips is that carbon-based chips of the same level have much better performance than silicon-based chips!

Carbon-based chips made with a 28-nanometer lithography machine can already match or even surpass 5-nanometer silicon-based chips in performance!

This is the biggest advantage of carbon-based chips compared to the current mainstream silicon-based chips!

It is also the real internal reason why Dongguo wants to achieve overtaking on corners in the chip industry.

A reporter from Central Media then asked:

"Since silicon-based chips have been developed for so long, there is a complete industrial chain in terms of manufacturing and use, and they are very mature!

"So even a genius like you can't beat the West on silicon chips?"

Chen Chong glanced at the somewhat stubborn central media reporter and smiled:

"This reporter friend, you have mistaken a core issue!"

"Why should I beat the West on silicon chips?"

"I don't have a disease in my brain, why should I continue on a road that has almost no way to go?"

Chen Chong looked at the many people who were thirsty for knowledge, sighed and explained.

This is an established conclusion that he has concluded based on his previous knowledge of carbon-based chips.

"Carbon-based chips will inevitably become the mainstream in the future!"

"Whether it is performance, efficiency or cost, it is much better than silicon-based chips!

"Silicon-based chips reach their physical limit below 2 nanometers!

"It wants to break through 1 nanometer, and the technology required is no less than the development of new technologies!

"The first direction of the new technology is carbon-based chips, and the second direction is quantum chips! 35

"Quantum chip, I won't mention it. Now this thing belongs to fantasy, and it belongs to the level of fishing for the moon in water, so don't think about it!""

"The number of transistors on a silicon-based chip doubles every 18-24 months, and the performance also doubles.

"So, according to Moore's Law, chips are improving every year, so what will happen if the chip breaks through 1 nanometer? 35

"TSMC's latest chip process is 4 nanometers. If the chip reaches the 2 nanometer process level, it will encounter an extremely terrifying technical bottleneck!"5

"Limited by materials, devices and quantum physics, problems such as leakage effect and short channel effect caused by quantum tunneling will appear!

"Therefore, the choice of new chip materials seems even more urgent."

"Silicon-based chip 2nm is the limit, and now TSMC has been able to achieve 4nm in the limit state! 35

"It's not far from reaching the physical limit!

"Moreover, the distance between these two nanometers requires more research and development effort than the research and development from zero to five nanometers! 39

"In this case, in a popular sense, in fact, silicon-based chips can already be said to have reached the limit!"

“There is not much room for development of silicon-based chips! 35

"Carbon-based chips are the road to the future!

"We have to develop a second strategy to disrupt the ambiguity of Western science and technology, and win in chaos!

"This is the real cornering overtaking!"

Only after hearing Chen Chong's explanation did the people on the scene and those watching the live broadcast truly understand the true meaning of overtaking in a corner...

"However, the biggest problem that hinders the development of carbon-based chips, apart from the lithography machine accident, isn't there the most difficult problem of graphene materials?

This reporter from the Central Media has already learned about it, so he asked this question.

Graphene is a scientific miracle.

Its thickness is only 0.335 nanometers, which is equivalent to 1/200,000th of a hair, but it is 200 times harder than steel!

And, this thing is 100 times more conductive than silicon and 10 times more thermally conductive than copper!

So, graphene's unique material properties make it do a great job.

If graphene is used to make carbon-based chips, its performance will be dozens of times that of silicon-based chips.

And the power consumption can be reduced to a quarter.

This is also the fundamental reason why Chen Chong said that carbon-based chips made by 28-nanometer lithography machines can surpass 5-nanometer silicon-based chips!

Manufacturing 5nm silicon chips requires an EUV lithography machine.

Then, it is also possible to manufacture a 5-nanometer carbon-based chip, which can be achieved by a DUV lithography machine.

(EUV: lithography machine below 10 nanometers; DUV: lithography machine that can only do about 25 nanometers.)

Carbon-based chips still cannot avoid the use of lithography machines, but at least reduce the demand for high-end lithography machines.

Chen Chong certainly knew that the question the reporter asked about graphene materials was the key to researching carbon-based chips.

5.4

When he finished writing the Julong EDA software code, he had already spent 5 billion to buy a complete set of civilian preparation methods for graphene wafer materials.

So, Chen Chong looked at the reporter and replied:

"I already have a very clear idea of ​​the preparation method of the popularization level of graphene wafer material!

"Otherwise, how dare I say that I want to lead the East to break through the electronic hegemony of the West?"

"Otherwise, why did I ask the Institute of Optoelectronics of the Chinese Academy of Sciences to send the country's only 22-nanometer DUV lithography machine here?""

Chen Chong put his hand on the lithography machine, took a deep breath, and said eloquently:

"Graphene wafer material problem!

"I'll fix it!"

"You can just wait and see the finished chip in two days! 39

"Oh, by the way, who can help contact Qualcomm's An Yu, and let him come over and watch the birth of the first real civilian-level police 5-nanometer carbon-based chip!""

"Don't Qualcomm like sanctions?"

"I want to announce the carbon-based chip sanctions bill on Qualcomm in front of him!"

"It's hard for me if he's not there!
