What is Ion Milling?

Ion Milling is a physical etching technique whereby the ions of an inert gas (typically Ar) are accelerated from a wide beam ion source into the surface of a substrate (or coated substrate) in vacuum in order to remove material to some desired depth or underlayer. It is easily visualized as "atomic sandblasting", or more accurately "ionic ...
