In this work, a conductive atomic force microscope (C-AFM) is used to study the reliability (degradation and breakdown, BD) of SiO 2 and high-k dielectrics. The effect of a current limit on the post-BD SiO 2 electrical properties at the nanoscale is discussed. In particular, the impact of a current
