Theoretical Modeling of EMP Effects in Semiconductor Junction Devices
Abstract
This report discusses various damage mechanisms and their effects on the performance of semiconductor devices, and some of the important theoretical models which are used to describe second breakdown phenomena. The dominant mechanism responsible for the occurrence of second breakdown is probably the thermal excitation of electrons from a device's valence band (thermal mode second breakdown); conclusions from theoretical calculations based on three different approximations seem to support this model. Current mode breakdown, another form of second breakdown, is discussed in terms of the role it plays in determining the shape of the threshold failure power curve. The purpose of this investigation is, therefore, to assess the existing models and known mechanisms which can cause damage to a p-n junction device in an electromagnetic pulse environment.
