Switching behaviours have been observed after gate dielectric breakdown under certain favourable conditions. In our recent report in IEDM 2009, the conductive breakdown path in gate dielectric can be “switched-off” if a reverse bias, as opposed to the stressing voltage, is applied, a condition required for observing SET and RESET conduction in bipolar switching material systems. Similar phenomenon...
Post breakdown (BD) reliability is an important area of study in ultra-thin gate dielectrics as it has significant implications on the performance degradation, lifetime, reliability margin and power dissipation of advanced sub-22 nm transistors and circuits. A prolonged phase of post-BD can ensure we can live with the circuit with moderate performance and error-free operation, even if the soft breakdown...
In order to achieve aggressive scaling of the equivalent oxide thickness (EOT) and simultaneously reduce leakage currents in logic devices, silicon-based oxides (SiON / SiO2) have been replaced by physically thicker high-κ transition metal oxide thin films by many manufacturers starting from the 45 nm technology node. CMOS process compatibility, integration and reliability are the key issues to address...
