This paper illustrates the application of a lumped element-finite difference time domain (LE-FDTD) simulator to the wide-band modelling of CMOS interconnections. To achieve very accurate results the short-open calibration (SOC) technique has been adopted. Specific parameters of a CMOS interconnection laterally screened by a stack of metal vias have been extracted in the two cases of an unperturbed and a purposely damaged metal line. The behaviour of void-like defects in the metal line has been also studied using the fully three-dimensional capabilities of the simulator. It has been demonstrated that, at least in the simulated cases, only the specific resistance is affected by damaging.

Abstract
This paper illustrates the application of a lumped element-finite difference time domain (LE-FDTD) simulator to the wide-band modelling of CMOS interconnections. To achieve very accurate results the short-open calibration (SOC) technique has been adopted. Specific parameters of a CMOS interconnection laterally screened by a stack of metal vias have been extracted in the two cases of an unperturbed and a purposely damaged metal line. The behaviour of void-like defects in the metal line has been also studied using the fully three-dimensional capabilities of the simulator. It has been demonstrated that, at least in the simulated cases, only the specific resistance is affected by damaging.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
