Actually the limit is a fair bit above atoms

"Transistor nodes have shrunk dramatically, with leading developers like
IBM advancing into the sub-1 nanometre realm (e.g., 0.7-nanometer tech).
However, absolute limits are rapidly approaching due to several factors:
Quantum Tunnelling: At sizes measuring just a few atoms across,
electrons no longer stay neatly in their channels. They start randomly
leaking or tunnelling through insulation barriers, resulting in massive
power loss and data corruption.
Atomic Boundary: The absolute physical limit for a silicon
semiconductor is effectively constrained by the size of the silicon
crystal unit cell (about 0.54 nm).
Heat Density: Shrinking transistors allows more components to be
packed together, but it creates extreme heat concentrations. The
challenge shifts from building them to keeping them cool without burning
out£
.....
I note that google can't spall 'nanometre' OR 'tunnelling; correctly
