The substrate is then exposed to chemicals which produce a solid material which condenses on its surface.
Finally, the etching takes place, which chemically removes layers from the surface of the substrate, leaving only the wanted pattern.
More generally, lithography is a term for printing onto a flat surface by coating it in a substance that repels ink except for where the pattern is supposed to be.
The word comes from the Ancient Greek words for ‘stone’ and ‘writing’.
