Abstract - Electrical characteristics or asymmetric n-MOSFET's with different source and drain geometry are experimently investigated using test structures having various gate width. Saturation drain current and resistance in linear region are estimated by a simple schematic model, which consists of conventional device having parasitic resistor. A comparison of experimental results of symmetric and asymmetric devices gives the parasitic resistance caused by abnormal device structure. The suggested model shows good agreement with the measured drain current for both forward- and reverse-modes.
