Dumb question: What unit of measurement is "A" in this context? Angstrom?

[–] Dudewitbow@lemmy.zip 10 points 2 months ago (1 children)

yes angstrom. we are st the age of fab nodes where nm isnt precise enough measurmenet under 3nm

Thanks. That's what I thought but guess I couldn't believe we were there. Last I really read (which has been a while), below 3nm, quantum tunneling became a problem. I guess we've addressed that in the fab process.

Remember that the reported nm resolution is kinda arbitrary and laced with marketing wank.
