Abstract
The electron saturation velocity in Silicon MOS transistors with channel lengths in the range 0.1-0.8 µm is studied for temperatures between 4.2K and 300K. A new method for the evaluation of the saturation velocity in a MOS transistor is presented. This method enables the drift velocity at source end of the device to be determined as a function of the corresponding electric field. The results obtained by this new method are compared to the ones obtained by classically used techniques and to literature data collected on resistive gated MOS devices.
