An ambient process was developed for producing both the dielectric and semiconductor layers of a zinc oxide‐based thin‐film transistor. The dielectric films exhibited good electrical properties, leading to devices with gate leakage less than 25 nA/cm 2 . Typical devices had mobilities in excess of 5 cm 2 /Vs from a process with a maximum substrate temperature of 200°C. In addition, devices showed reasonable electrical stability in this novel deposition process for dielectrics and semiconductors.
