Abstract

This paper presents a yield optimization tool, FlexiOptimizer , for flexible thin-film transistor (TFT) circuits. FlexiOptimizer considers three important effects: (1) process variation; (2) aging effect; and (3) bending effect. This SPICE-based optimizer applies response surface methodology (RSM) and orthogonal array (OA) techniques to size transistors so the yield is improved in aged and bent condition. This tool is demonstrated on two different designs: organic light emitting diode (OLED) pixel drivers and differential operational amplifiers (OPAMPs), in both amorphous silicon (a-Si) and Indium-Gallium-Zinc-Oxide (IGZO) TFT technologies.
