NanoMill system's concentrated argon ion beam, typically in the energy range of 50 to 2000 eV, excels at targeted milling and specimen surface damage removal. Ioninduced secondary electron imaging is used to locate the FIBproduced lamella and then to target the region that will receive low energy milling in either raster or spot modes.
Ion beam figuring as a contactless processing method One of the main advantages of ion beam figuring is the contactless nature of the ion beam as a working tool, which eliminates the ageing effects of commonly used mechanical tools. The method also allows an excellent stability of the removal rate and avoids mechanical subsurface damages on
We have investigated reactive ion beam etching of semiconductor and insulator materials using gases, such as CF4 and C2F6, and compared the etching rates with those of argon ion milling. The ion beam is generated by a Kaufman‐type ion source, in a milling system manufactured by the Commonwealth Scientific Corporation. When a number of semiconductors such as InGaAs, InP, GaAs, Si, and Ge are ...
Ion Beam Milling thins samples until they are transparent to electrons by firing ions (typically argon) at the surface from an angle and sputtering material from the surface. A subclass of this is Focused ion beam milling, where gallium ions are used to produce an electron transparent membrane in a specific

reserved for focused ion beam systems. Other alternatives for preparing crosssections rely on mechanical or cleaving methods which often distort or induce damage. The IM4000 Ion Milling System utilizes a broad, lowenergy Ar+ ion beam milling method to produce wider undistorted crosssections without applying mechanical stress to the ...
The 4Wave IBE20B ion milling system uses a broad argon ion beam to controllably and uniformly remove material from a user's substrate. A secondary ion mass spectrometry (SIMS) endpoint detector can stop etching within nm of the interface between two dissimilar materials.

,34) Therefore, we focused on argon (Ar) ion beam milling, because it is not a complicated chemical dry etching process, but a simple physical one. A silica surface of imprint molds without a ﬂuorinecontaining passivation layer on sidewalls can be maintained.

ion beam lithography and transferred to the superconducting fn by argon ion milling. Lines in SOnmthick films had the same zeroresistance temperature (89 K) as the starting films, and a critical current density of ~ lo6 A/cm2 at 77 K, representing a threefold reduction from the starting value.
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 outer space, and can be an unwelcome source of wear in precision components. However, the fact that it can be made to act on extremely fine layers of material is exploited ...
A thin cross sectional film is prepared by milling surface layer atoms with the irradiation of an argon ion beam accelerated at 2 kV to 10 kV with a grazing incidence angle less than 10°. The disadvantage of ion milling is that damage to the specimen is unavoidable.
Ion Beam Etching (or Milling) is a dry plasma etch method which utilizes a remote broad beam ion/plasma source to remove substrate material by physical inert gas and/or chemical reactive gas means. Like other dry plasma etch techniques, the typical
