I mean the parent comment mentioned tests…

You would also port the tests, right?

Waterproof and repairability are really at odds.

They use electron beams and extreme UV light nowadays. Lasers are not necessarily the best light source, even at other wavelengths.

Like glueing a cardboard to the wall and then dissolving it after spraying :)

Photolithography started as a printing technique and is pretty basic.

You start with macroscopic photolithography, add material science of semiconductors and then iterate a million times. It didn’t start at nanoscale.
