Abstract
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.
