We report the fabrication of solution-processed Indium zinc oxide(IZO) transistors using inkjet printing. A IZO ink was prepared by dissolving indium nitrate, zinc acetate into 2-methoxyethanol. The compositions of dropped IZO films have high stoichiometric characteristics with low carbon impurity. Depletion mode IZO field effect transistors were fabricated showing a field-effect mobility of 0.2cm2/Vs. An electrically and thermally biased stability showed a threshold voltage deviation of 1.46V for 3hours.
