Web1 Aug 1971 · Surfaces of Ti, W and Si have been cleaned in an ultra high vacuum system by ion bombardment with Cs + and Ar +.Also a thin film (220 Å) of Si 3 N 4 on Si has been etched off by sputter-etching with Cs + at 500V. The surface composition was monitored with Auger spectroscopy, film thickness with ellipsometry and work function changes with … WebFigure 9.15. Influence of sample cleaning on XPS scans taken on a thin-film superconductor, (a) Survey scan from an as-received surface, (b) Survey scan from surface after ion-beam (sputter) cleaning. Note the reduction in the Cls peak after cleaning, (c) Comparative Ba3d scans from both cases. Note the change in shape and size as the surface ...
Sputter cleaning became an integral part of the ion plating process. When the surfaces to be cleaned are large, a similar technique, plasma cleaning , can be used. Sputter cleaning has some potential problems such as overheating, gas incorporation in the surface region, bombardment (radiation) damage in the … See more In physics, sputtering is a phenomenon in which microscopic particles of a solid material are ejected from its surface, after the material is itself bombarded by energetic particles of a plasma or gas. It occurs naturally in See more The term electronic sputtering can mean either sputtering induced by energetic electrons (for example in a transmission electron microscope), or sputtering due to very high-energy or highly charged heavy ions that lose energy to the solid, mostly by electronic See more Removing atoms by sputtering with an inert gas is called ion milling or ion etching. Sputtering can also play a role in reactive-ion etching (RIE), … See more • Thin Film Evaporation Guide • What is Sputtering? - an introduction with animations See more When energetic ions collide with atoms of a target material, an exchange of momentum takes place between them.
