IBM VTFET: Vertical Transistors of the Future

IBM and Samsung just announced VTFET: Vertical Transport Field Effect Transistors. In this video I will first give a brief introduction over the recent transistor history, from planar FETs to FinFETs and RibbonFETs and then explain why a vertical approach to transistor design solves many of today limitations in semiconductor fabrication.

I found this extremely useful as I want to invest in the transistors category. It’s hard to find technical information that is short and allows me to learn if a certain company has a competitive advantage. Thank you for the taking the time to explain.

[bertangundogdu]

This is the best explaination yet, well done and thank you.

[Eagervul]

Oh wow, only 500 views??? You're underrated heavily. Keep up the good work!

[not_yourbusiness]

Great source of information for CS student. I appreciate the material 👍

[danielraymadden]

Good video....better than most....active operation illustrations are

[helvetiaresearch]

Don't forget that interconnect resistance limits clock rate now days too.

[ghipsandrew]

Fantastic video and explanation. I glad I gave your video a view - happy holidays!

Simple design innovations with large impacts are always my favorite! Just goes to show you that no matter how much we evolve around or on top of something, all it can take is that one thing, that was once certian to be turned sideways and then EVERYTHING changes.

[THE-X-Force]

I learned a lot from this. Thank you very much. (first time here btw .. I'll be back)

"We need to blink twice and it will be a reality" as opposed to clicking our heels three time and saying 'there's no place like home'. 🤣 great video 👍

Hi, great video, but I was wondering what is the difference between a CFET and a VTFET?

[adinchandra]

Transistor design always evolve. And yes, means better performance and efficiency for Most Computing devices

[questmarq]

Can you do a video explaining the new breakthrough in Adaptive transistor 85% germanium efficiency?

[RM-elgw]

Cool stuff. I wonder how these new transistors will compete with current technology in terms of price - wouldn't the manufacturing costs be higher given the increased complexity in production, even after optimizing production lines etc?

That being said, it's great to see things like this in development. It all seems like magic to me.

[andrewl]

I’m really worried about interconnect limitations for this

[ydvisual]

Hey High Yield! Great info thank you! What I don't understand is the single vtfet diagram by IBM has one drain, one source and one gate(blue color). But in the the larger image with many many vtfets together in rows, the gate(blue color) is in the middle between TWO drains and TWO sources... Why is that? and sometimes there is no gate(blue tall thing)...

[SianaGearz]

Mhm. How does vtfet help reduce gate capacity, if everything is larger? Isn't this necessary to help reduce switching power consumption to harvest efficiency gains from the upcoming processes? Or you say with every shrink, leakage current becomes larger, so how did newer semiconductor nodes become more power efficient so far over time?

I wonder if they're planning to make vtfets as complimentary pairs stacked on top of each other as well for better space efficiency... or even eventually a fully vertical universal gate?

I should say the video wluld have been more comfortable with more Broll from the infographic animations. In a pinch, just pause on the broll or loop it or both to give us more time to inspect it. Not fatally so but you know quality of life features.

[joechang]

you are too young to remember this, back in 1980's, there was the permeable base transistor, in which transport was vertical, though different than this. The first(?) wafer showed outstanding performance characteristics. Everyone was really excited. But every subsequent attempt to produce new wafers were nowhere close to the original. they kept doing research on devices from that first wafer. and eventually gave up?

[Kneedragon]

... well the first thing I notice, is it's CLEARLY going to take up less space. That's going to result in a BIG jump in transistor density.
Improvements in speed or efficiency are like Ford of General Motors telling you about higher power, or higher mileage. That's great, but what the car company cares about is margin and profit and cost of manufacture. You increase transistor density and that's money in Intel's pocket.

What is the difference between GAAFET and VTFET?
