Gu. Reinsperger et al., QUANTITATIVE COMPOSITION ANALYSIS OF SEMICONDUCTING SILICIDE FILMS, Physica status solidi. a, Applied research, 145(2), 1994, pp. 425-428
FeSi(x) films of various compositions prepared by magnetron sputtering
are investigated by Rutherford backscattering spectroscopy (RBS) and
Auger electron spectroscopy (AES). RBS is used as a reference method f
or quantitative AES analysis. Auger sensitivity factors for Si and Fe
in FeSi(x) are determined experimentally. It is shown that the altered
layer forming during sputtering of FeSi(x) is enriched in iron.
