I highly doubt it will be that much initially. Silicon is pretty hard.

The stamp doesn't touch the silicon or any other solid material, it hovers just above.

It only touches a liquid photo-resist that is spread on the wafer. The stamp is transparent, which allows UV light to shine though and exposes the photo-resist, which solidifies into a mask matching the stamp.

Ah ok! I thought the two were actually in contact. Ok, in that case they might get some life out of them.
