Abstract :
Issues associated with the integration of p-type band-edge (5.0~5.2 eV) effective work function (EWF) electrodes are identified and discussed. The Fermi-level (Ef) pinning effect traditionally used to explain the lowering of p-MOS EWF is believed not to be an intrinsic limitation. However, a new described as the "flatband (Vfb,) rolloff effect" is shown to be the dominant factor.
