摘要: An efficient and accurate 2D analysis for gate-current is proposed for short channel n-MOSFETs, in which the channel hot-electron-enhanced injection probability is proposed and expressed in terms of the actual current path and its power density flow. The accuracy of our gate-current analysis has been verified by comparisons between simulation and experimental data. This well-established gate current analysis as well as the charge boundary condition on the floating gate have been implemented into the sub-micron MOS (SUMMOS) two-dimensional device simulator for characterizing n-channel flash EEPROM writing. Comparisons with experimental EEPROM writing have been made, and quite good agreements have been obtained for test devices with different channel lengths ranging from 0.8 to 0.5 mu m for wide range of applied biases. Moreover, computer simulation for EEPROM reliability issue caused by oxide electron traps has also been performed to characterize the endurance of flash EEPROM operation.
