Semiconductor Industry future timeline for cmos 5nm

[Puppet123]

Hello,

We are already at 5nm in CMOS.

How much longer with the modern day semiconductor industry last for ?

5 years ? 10 years ? 2 years ?

I am talking about Analog IC, Mixed Signal IC and RF IC design.

Let me know what you think !

I have watched willy sansen's lecture on this in ISSCC 2015.

I was surprised when he predicted we're going to move to vertical nanotubes.
As long as the I-V characteristics are similar, the experience gained from bulk CMOS are the same for technology changes

nanotubes already failed, pretty much. we didn't find a way to make good contacts, so the CMOS/tube interface never worked as it should have worked.

Of all the crap that has been proposed in the last 10 years, gate all around is probably the most promising. End of the day, the industry will switch to whatever is the low-hanging fruit. We will be stuck with finfets until 3nm or so, then something else will come through, whatever that something else might be.
