Heavy Ion Elastic Recoil Detection (Heavy Ion-ERD) analysis is now an established thin film depth profiling analysis technique. But it is not without artefacts.The main aim of this study is to investigate the effects of the probing beam on the structure (i.e. thickness, atomic composition, crystallinity, roughness) of metallic thin films after Heavy Ion ERD analysis using 26 MeV Cu7+ beams. Heavy Ion ERD analysis was carried out to determine the thickness and the depth profile of ZrN and NbN thin films prepared through RF magnetron sputtering deposition on silicon substrates. The structural characterization of these thin films was carried out before and after Heavy Ion ERD analysis to check for beam effects on the films. Possible beam damage on the surface of these thin films was assessed by various techniques such as; Rutherford Backscattering Spectrometry (RBS) which was used to determine (any) changes in film thickness and composition, Atomic Force Microscopy (AFM) used to obtain the surface roughness and morphology of the thin films and X-ray diffraction (XRD) used to determine the crystallinity and the residual stress. This presentation discusses findings made from the measurement results.
