We apply a particular course of SCM analysis for the 2D-dopant profiling of
Power MOSFETS revealing reduced breakdown voltages. The reliability of thi
s analysis is ensured by comparisons of failed devices to reliable referenc
es. Our analysis strongly suggests that the reduced breakdown voltages resu
lt from deviations of the depths of particular p-wells (2.52 +/- 0.07 mum)
from the regular value (2.29 +/- 0.07 mum) as measured at references. (C) 2
