Abstract:
1. A process comprising: fabricating a thin film transistor comprising in any effective arrangement a semiconductor layer, a gate dielectric, a gate electrode, a source electrode, and a drain electrode, wherein at least one of the source electrode and the drain electrode comprises a suitable amount of zinc, indium, or a mixture thereof, wherein the semiconductor layer is formed by a semiconductor fabrication process comprising: liquid depositing one or more zinc oxide-precursor compositions and forming the semiconductor layer comprising polycrystalline zinc oxide from the liquid deposited one or more zinc oxide-precursor compositions; and wherein the semiconductor layer fabrication process further comprises heating the deposited composition and cooling the heated deposited composition; and wherein the zinc oxide precursor composition comprises a zinc compound, a solvent, and a complexing agent selected from the group consisting of a carboxylic acid and an organoamine.
