WebFocused-ion-beam machining is a powerful process fabricatto e complex nanostructures, often through a sacrificial mask. that enables milling beyond the resolution limit of the ion beam. However, current understanding of th superis -resolution effect is empirical in the spatial domain and nonexistent in the temporal domain. WebIon Beam Etching (or Milling with inert gases) is achieved by directing a beam of charged particles (ions) at a substrate with a suitably patterned mask in a high vacuum chamber. It enables highly directional beams of ions – whose space-charge is neutralised by electrons from the neutraliser - to control the etched sidewall profile as well as ...
