Depth Profiles of Al/Mn/Si Multilayers

An electron scattering model called IntriX associated to electron X-ray emission spectrometry (EXES) at high resolution is tested to characterize stratified samples. The ability of the model to simulate the X-ray intensity emitted by a surface layer and a buried layer in film/substrate systems is illustrated. The characterization of Al/Mn/Si multilayers by means of non destructive techniques (electron probe microanalysis (EPMA), Rutherford back scattering (RBS)) have been performed comparatively to the EXES measurements. The potentialities of the IntriX model combined to EXES to predict thicknesses is established by comparison with EPMA and RBS results
