Academic tyrant: I have become a prodigy since I was able to pursue my academic career with peace of

In the laboratory, experts are discussing enthusiastically

"The fundamental physical limitations of silicon materials at the atomic scale make the evolution path of silicon technology driven by Moore's Law seem to be rapidly approaching the end point"

"As Moore's Law comes to an end, artificial intelligence, the Internet of Things, supercomputing and related applications have put forward higher performance requirements. The semiconductor industry has entered a critical point in urgent need of transformation and breakthrough development. Chip architecture, materials, integration, processes and Innovative research in security has become a new breakthrough direction.

Another expert sneered and said,"You don't need to talk about these theoretical aspects at all. No one here knows. The question is where to start now, where to start!""

"Is there a breakthrough in research on new architecture transistor technology?"

"No, not at all"

"Dean Chen, give me a plan?

Chen Fan frowned slightly,"Fin field effect transistors are the transistor architecture used in the current mainstream semiconductor manufacturing process. Which of you has done research on this aspect?""

He glanced at everyone and said

"��I can do that. One of them raised his hand and said,"But the transition from 22nm to 7nm has been eliminated. Currently, we need to expand to 5nm and 4nm process nodes. This is quite difficult.""

"For this reason, I personally believe that the gate-all-around transistor is a more mainstream technology that continues to extend the life of the existing semiconductor technology route. It can further enhance gate control capabilities and overcome the physical scaling and performance limitations of current technology."

Chen Fan nodded slightly. This is a good method, but the problem is that it is outdated.

"Recently, Hanguo Five-Star Electronics has abandoned the finfet architecture and switched to the gaafet architecture starting from 3 nanometers. It has started trial production and will start mass production from the beginning of next year.

He paused here and said,"So, even if the gate-all-around transistor is broken, it will be of no use." Our speed is too slow.

It is better to focus on complementary field effect transistors, vertical nanowire transistors, negative capacitance field effect transistors, and tunneling field effect transistors."

As soon as these words came out, everyone present was stunned at the same time.

"Dean Chen, when did this happen? Why haven’t we heard any news?"

"Yes, has the technology of this cold country reached this point?"

"impossible!"

Everyone is a little unbelievable. They haven't even produced seven-nanometer transistors here, and now Han Country has moved to the 3-nanometer field.

Isn't this a heavy blow!

"Of course there is a source."Chen Fan said calmly,"You don't have to worry about this, just do what I say."

He has Xiaoqiang, so he can naturally see some top-secret information that others cannot see.

Everyone went to work.

But according to the current progress, everyone is a little discouraged.

They thought that following Chen Fan would be much faster.

But Now it seems that it is not very fast.

Then I thought about it, how could something like a chip be achieved overnight? Chen

Fan was alone in the room, frowning slightly.

, developing new electronic devices is another solution to the current bottleneck of chip development.

Perhaps he can completely abandon the existing chip redemption and directly study silicon-based materials.

Currently, alternative semiconductor materials mainly include third-generation semiconductors.

materials, carbon-based nanomaterials, two-dimensional semiconductor materials, etc.

The third generation of semiconductor materials includes wide band gap semiconductor materials represented by silicon carbide, gallium nitride, zinc oxide, diamond, aluminum nitride, gallium oxide, etc.

, which can achieve high voltage.

, high temperature, high frequency and high radiation resistance, it is praised by the industry as the"core" of solid-state light sources, power electronics, microwave radio frequency devices and the"new engine" of the optoelectronics and microelectronics industries.

Moreover, currently, silicon carbide transistors and nitrogen.

The research and development of gallium transistors is relatively mature and can cooperate with 5g communication technology, hydro-hydrogen new energy vehicles, optoelectronic devices and other markets, and the profits from this will be very considerable.

Chen Fan drank.

A mouthful of water, but the problem comes again.

Technetium Infineon has developed a series of silicon carbide metal-oxide semiconductor field-effect transistors and discrete devices.

Meiguo Cree invested US$1 billion to build a silicon carbide super manufacturing plant.

The silicon wafer manufacturing capacity has increased from 2 times to 30 times at the beginning.

It can be said that it can fully meet the expected market growth in the past ten years or so.

Meiguo Yipu Power Conversion Company launched the first commercial enhanced model as early as 2010.

Gallium nitride transistors.

Currently, more than 100 gallium nitride products are provided for wireless power transmission, fully autonomous vehicles, high-speed mobile communications, low-cost satellites, medical care and other applications.

The island country AGC has teamed up with NCL to develop this gallium oxide wafer.

One by one, it is enough to show that if Xia Guo wants to achieve success in the chip field, it must also throw away their technologies and leave them far behind.
