Abstract :
Experimental verification of substrate current characteristics is thoroughly carried out. VDS- VDSAT, instead of VDS, is shown to be the driving force of all hot-electron effects. A simple relationship between substrate current and VDS- VDSATis found. This relationship provides a convenient tool to characterize the substrate current or the channel electric field, and, hence, all hot-electron effects. Measurements of ISUB/IDand VDS- VDSATat two bias points and any one channel length are sufficient to fully characterize the substrate currents for all channel lengths VDS´s and VG´s for a given technology.
