The effective work function (EWF) extracted on terraced oxide structures by capacitance-voltage-based techniques was compared with the work function calculated from the barrier height extracted by current-voltage measurements. The results show a reasonable correlation-within ± 0.1 eV - in the EWF values for various metal gate electrodes, validating both techniques for EWF extraction. © 2006 IEEE.
