摘要

Graphical abstract Display Omitted Highlights Four strategies compared to characterize Al2O3 thin films on anisotropic polymeric substrates. Film thickness and optical constants are determined with spectroscopic ellipsometry (SE) and Mueller matrix methods. Strategies are provided for both ex situ and in-line measurements. Abstract Spectroscopic ellipsometry characterization of coatings on polymeric substrates can be challenging due to the substrate optical anisotropy. We compare four characterization strategies for thin coating layers on anisotropic polymeric substrates with regard to accuracy of the resulting layer thickness and coating optical constants. Each strategy differs in measured data type, model construction, implementation complexity, and inherent capabilities and sensitivity to the coating properties. Best practices and limitations are discussed for each strategy.
