TY - JOUR A1 - Duwe, M. A1 - Quast, J.-H. A1 - Schneider, S. A1 - Fischer, Daniel A1 - Beck, Uwe T1 - Thin-film metrology of tilted and curved surfaces by imaging Mueller-matrix ellipsometry T2 - Journal of Vacuum Science & Technology B N2 - For the vast majority of ellipsometric measurements, the application of planar substrates is mandatory and requires a proper sample alignment prior to the measurement. Here, the authors present a generalized approach of how to extract the isotropic ellipsometric sample parameters from an imaging Mueller-matrix measurement even if the sample is significantly misaligned. They validate the method by layer-thickness calculations based on imaging Mueller-matrix measurements of flat crystalline silicon samples that were misaligned on purpose. Furthermore, they also exploit this method’s capabilities to perform spatially resolved layer-thickness measurements of a single-layer indium-tin-oxide coating on a fused-silica microlens without the need of realignment or repositioning of the sample during the measurement.
