Considering asymmetry caused by layout, process, and device degradation, separate extraction of the source and drain resistances, i.e., RS and RD , respectively, from the total resistance R TOT is very important in the design, modeling, and characterization of amorphous indium-gallium-zinc oxide (a-...
