The analysis of semiconductor devices in research and development has to deal with: Narrow structures (up to few micrometers),Thin layers from 0.01 to 10 micrometers,Low concentrations of doping elements. The SIMS technique has been extensively used for depth profiling of dopant distribution in large analyzed areas. In this paper,some examples of depth profiles obtained in transistors as small as 4 micrometers across will be shown.
