P‐16: Implementation of TCAD Simulation of a‐IGZO Corbino TFTs for AMOLED Application

Abstract

We studied the effects of Corbino structure amorphous indiumgalium-zinc oxide (a-IGZO) thin film transistors (TFTs) using TCAD and circuit simulator. The Corbino structure shows the special behavior with drain electrode in inner or outer. By simulation, we confirm the Corbino structure have better performance than conventional structure for AMOLED pixel circuit.
