And thicker still than Sound Labs at 2.5 microns , posted on May 2, 2022 at 05:50:55

People always seem impressed by 2.5u or whatever.
But in semiconductor processing? That's HUGE and thicker than any single feature of such devices.
We'd deposit 1.2u Metal.....and for a POWER device, that's what it takes.
For a logic device? I don't remember any more, but 0.5 or 0.6 kindof rings a bell.
Don't forget that 10,000 Angstroms is 1u.......Gate Oxide will be .025u and other films proportionally thin.....

The device shown uses semiconductor processing technnques.....To make it a roll-to-roll process will take some doing but I think CAN be done....
Too much is never enough
