Abstract: A test method and apparatus are provided for predicting hot-carrier induced leakage over time in IGFET's. Test results are used to show how choice of channel length and stress voltages critically affect hot-carrier-induced leakage (HCIL) leakage over time, particularly in devices having submicron channel lengths. Models are developed for predicting leakage current over the long term given short term test results. Alternative design strategies are proposed for reliably satisfying long term leakage requirements.
