We fabricated In-Ga-Zn-O (IGZO) thin film transistors (TFTs) employing solution-processed aluminum oxide (Al2O3) gate insulators with various thicknesses from 100 nm to 370 nm. Leakage current density of Al2O3 gate insulators decreased exponentially and dielectric constant decreased with increasing insulator thickness. When the thickness of gate insulator was 230 nm, the sputtered IGZO TFT showed 9.00 cm2/Vs of the saturation mobility and 3.4 V of the threshold voltage.
