Abstract
In this work we compare simulations of SCM measurements on bevelled and mic ro-sectioned samples for investigating the impact of the carrier spilling e ffect. Simulation results are validated by experimental data obtained from dedicated samples calibrated by spreading resistance profiling. We show tha t 3D-based direct inversion of data measured on micro-sectioned bipolar sam ples results into a good quantitative agreement with the experimental sprea ding resistance profile in the area where carrier spilling is negligible. 2 D-based simulations of bevelled bipolar samples reproduce qualitatively the measured SCM profiles. These results lead to the conclusion that also in t he case of SCM, the lateral resolution in junction delineation can be impro ved by characterizing bevelled samples. (C) 2001 Elsevier Science Ltd.
