Thin-film polycrystalline Tin with an approximate 2 nm thick native TiO{sub 2} overlayer is bombarded with 50 to 200 eV Ar ions in an electron cyclotron resonance plasma. In situ X-ray photoelectron spectroscopy and static secondary ion mass spectrometry suggest complete removal of oxygen from the planar surface, independent of ion energy, with TiO{sub 2} remaining on the columnar grain boundaries. The TiN etching rate increases from 6 to 14 nm/min as the ion energy is raised from 100 to 200 eV. The TiN stoichiometry does not change with ion bombardment.
