Abstract
Several studies of plasma-assisted etching were reported in the mid-1970s which demonstrated the importance of energetic ion bombardment [1–3]. In this work the terms chemical sputtering [2] and reactive ion etching RIE [3] were introduced. Subsequently, directed beam studies [4] showed more clearly the synergism between energetic ions and chemically reactive species incident on surfaces on which the reactive species can react with the surface to form volatile products.
