A good understanding of the fabrication process of reproducible functional metal-polymer interfaces is of high importance for their use in organic electronics. Sputter deposition offers the ability to precisely control and tailor the fabrication of metal-polymer interfaces. During sputter deposition, the evolution of the metallic layer morphology is monitored in-situ with time-resolved grazing-incidence small-angle X-ray scattering (GISAXS). The resulting in-situ scattering data is processed and analyzed using the DPDAK software package. By fitting the processed data, structure parameters can be extracted whose temporal evolution reveals the mode of metal growth on polymer surfaces. Simulations with BornAgain lead to a deeper understanding of the growth mechanism of sputter deposited metal-polymer interfaces.
