abstract = {Modern nanotechnology is constantly raising demands to
quality and purity of thin films and interlayer interfaces.
As thicknesses of employed layers decrease to single
nanometers, traditional characterization tools are no longer
able to satisfy throughput, precision or non-destructibility
requirements. Extreme ultraviolet (EUV) and soft X-ray
reflectometry has not only demonstrated the ability to
detect sub-nm thickness variations but also was shown to be
very sensitive to chemical composition changes. Since the
laboratory radiation sources in this wavelength range often
emit in a relatively broad spectral range, a spectroscopic
EUV reflectometry has been developed with the added benefit
of a rapid measuring time on the order of milliseconds to
seconds. In this paper, the extension of the method to
multi-angle measurements will be presented. It allows to
reduce a number of fit parameters in the analysis model,
making the method suitable for complex samples of unknown
composition. First experimental examples for Si-based layer
systems measured under grazing incidence angles between 2°
and 15° will be demonstrated and discussed. (© 2015
