The generation of defects in ultra-thin SiO gate layers and SiO / ZrO gate stacks is studied through the time-dependent 2 2 2 current density variation DJ (t) 5 J (t) 2 J (0) observed during constant gate voltage stress of MOS capacitors. The time G G G dependence of the defect density variation DN
