Implanted and irradiated SiO2∕Si structure electrical properties at the nanoscale

Abstract

In this work, a conductive atomic force microscope (C-AFM), a scanning capacitance microscope (SCM), and a kelvin probe force microscope (KPFM) have been used to qualitatively study at the nanoscale the electrical properties of irradiated and implanted gate oxides of metal-oxide-semiconductor structures. These techniques have allowed to investigate the electrical conduction (C-AFM) and the presence of charge (SCM and KPFM) in the oxide of the analyzed structures. The impact of the energy of the impinging ions has also been qualitatively evaluated.
