Abstrakt: Various conventional and novel electrical characterization techniques have been combined with comprehensive analysis to properly evaluate high-k gate dielectric stack structures. These measurement methodologies and analysis techniques are intended to separate contribution from the pre-existing defects, which may serve as charge traps, from the stress-generated defects. In addition, the differentiation of electrically active bulk high-k traps and interfacial layer traps has been demonstrated.
