Web29 jan. 2024 · EUV lithography machines today have sophisticated systems to emit precisely timed droplets of tin, which are then hit with a powerful laser beam, superheating the tin into plasma. The heated plasma then emits EUV light, but dissipates considerable energy in the process.

WebDirect write atom lithography is a technique in which nearly resonant light is used to pattern an atom beam. Nanostructures are formed when the patterned beam falls onto a substrate. We have applied this lithography scheme to a ferromagnetic element, using a 372 nm laser light standing wave to pattern a beam of iron atoms.
