Low energy ion sputtering for depth profiling in SIMS, AES and XPS pro
duces sputter induced artifacts. These effects are studied by comparin
g RBS spectra of the bombarded layer to the original target compositio
n. For this purpose an automated RBS chamber has been built combining
an Atomika SIMS system and a NEC microprobe RBS beam line. In this art
icle the effect of ion beam mixing of Pt on Si and of CoSi2 on Si unde
r oxygen bombardment, as well as the preferential sputtering of Si in
CoSi2 under Ar bombardment are demonstrated.
