We reported the fabrication of indium-gallium-zinc oxide (IGZO) thin-film transistors (TFTs) by plasma-enhanced atomic-layer-deposition (PEALD) process using different surface reactivities of the precursor-substrate combinations with controlled deposition sequences. In-Zn-Ga (Case II) exhibited favorable subthreshold swing (SS) values of 313 mV/decade, and moderate mobility (μFE) of 29.3 cm2/Vs compared to In-Ga-Zn (Case I) (84 mV/decade and 33.4 cm2/Vs).
