Abstract
The redistribution of As during the solid state reaction of nickel thin films with a n-doped (1 0 0) Si substrate has been analysed by secondary ion mass spectrometry (SIMS), X-ray reflectivity (XRR) and sheet resistance measurements. Heat treatment between 400 °C and 650 °C leads to the formation of the monosilicide (NiSi) and to very different SIMS depth profiles of As. The role of the agglomeration of NiSi on the SIMS measurements of As redistribution and particularly on As concentration at NiSi/Si interface is shown.
