Abstract: Fabricating thin metal layers and particularly observingtheir formation process in situ is of fundamental interest to tailor thequality of such a layer on polymers for organic electronics. Inparticular, the process of high power impulse magnetron sputtering(HiPIMS) for establishing thin metal layers has sparsely been exploredin situ. Hence, in this study, we investigate the growth of thin gold(Au) layers with HiPIMS and compare their growth with thin Aulayers prepared by conventional direct current magnetron sputtering(dcMS). Au was chosen because it is an inert noble metal and has ahigh scattering length density. This allows us to track the growingnanostructures via grazing incidence scattering. In particular, Audeposition on the polymer polystyrene (PS) with the respectivestructural analogues poly-4-vinlypyridine (P4VP) and polystyrenesulfonic acid (PSS) is studied. Additionally, the nanostructured layers on these different polymer films are further probed by fieldemission scanning electron microscopy (FESEM), atomic force microscopy (AFM), X-ray reflectometry (XRR), and four-pointprobe measurements. We report that HiPIMS leads to smaller island-to-island distances throughout the whole sputter process.Moreover, an increased cluster density and an earlier percolation threshold are achieved compared to dcMS. Additionally, in theearly stage, we observe a significant increase in coverage by HiPIMS, which is favorable for the improvement of the polymer−metalinterface.
