WebThis paper assesses the current status of these dielectrics and their processing in terms of types of dielectric (and their stacks), pre-deposition treatments, deposition methods, post-deposition treatments, and their viability in actual devices. Time-dependent gate oxide breakdown (or time-dependent dielectric breakdown, TDDB) is a kind of transistor aging, a failure mechanism in MOSFETs, when the gate oxide breaks down as a result of long-time application of relatively low electric field (as opposed to immediate breakdown, which is caused by strong electric field). The breakdown is caused by formation of a conducting path through the gate oxide to substrate due to electron tunneling current, when MOSFETs are operate…
