Title
Oxide conductivity increase during the progressive-breakdown of SiO2 gate oxides observed with C-AFM
Abstract
In this work, the high lateral resolution of the Atomic Force Microscope (AFM) related techniques has been used to investigate the progressiveness of the breakdown event (BD) at a nanometer scale on thin (2.9 and 4.2 nm) gate oxides. In particular, the contribution of the oxide conductivity (at the position where BD is initially triggered) to the overall post-BD conduction of the spot has been analysed. The results show that this parameter plays an important role in the gradual increase of the post-BD gate current during the progressive breakdown. (C) 2003 Elsevier Ltd. All rights reserved.
