1. Electron beam lithography
Electron beam lithography (e-beam lithography) is a direct writing technique that uses an accelerated beam of electrons to pattern features down to sub-10 nm on substrates that have been coated with an electron beam sensitive resist.
Exposure to the electron beam changes the solubility of the …
