Evaluation of thickness, density and interface width of thin films by X-ray reflectometry. Instrumental requirements, alignment and positioning, data collection, data analysis and reporting Ingestion-build-205840 This European Standard specifies requirements1 Scope This document specifies a method for the evaluation of thickness, density and interface width of single layer and multi layered thin films which have thicknesses between approximately 1 nm and 1 m, on flat substrates, by means of X Ray Reflectometry (XRR). This method uses a monochromatic, collimated beam, scanning either an angle or a scattering vector. Similar considerations apply to the case of a convergent beam with parallel data
