L. Ciampolini et al., Simulation of scanning capacitance microscopy measurements on micro-sectioned and bevelled n(+)-p samples, MAT SC S PR, 4(1-3), 2001, pp. 85-88
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. All
