Popis: In this work, we demonstrate for the first time 3D-carrier profiling in FinFETs with nm-spatial resolution using SSRM. The results provide information on gate underlap, dopant conformality, source/drain doping profiles. The 3D-carrier profiles as extracted for two different device approaches (extensions vs. extension-less) are conclusive in demonstrating the differences in device performance and are consistent with first order 3D-simulations.
