Abstract

We report the high drain current amorphous iitdium-gallium-zinc-oxide (a-IGZO) thin-film transistors (TFTs) with excellent performance uniformity by using bulk accumulation (BA) mode. In our previous papers, the optimization conditionsfor BA mode were found to be thin and low density of states in the gap of active layer, low interface state density between IGZO and gate insulator. The instabilities such as positive bias-stress, high current stress and hysteresis are studied for these TFTs and have a conclusion that highly stable a-IGZO TFT with exceeding effective mobility over 50 crrf/Vs can be achieved. The high performance TFTs could be applied to high yield and fast response integrated gate drivers for AMOLED andAMLCD.
