Ion Milling – ORION-8-IM System

Ion MillingORION-8-IM System, AJA Int. Inc.

Ion milling is a dry etching method used for creating thin film patterns. The process of ion milling takes place in a vacuum chamber in which ions Ar are accelerated by the ion gun towards the sample and bombard the areas of the sample uncovered by a mask. The collisions of the Ar ions with the surface of the film gradually remove surface atoms of the surface. This method is superior to wet chemical etching and lift-off process because it does not involve chemical reactions or film straining. It allows to remove of layers of materials with atomic precision and to form nano-sized patterns.
