Abstract

We report on the fabrication of ZnO-based dual gate (DG) thin-film transistors (TFTs) with 20-nm-thick AI₂O₃ for both top and bottom dielectrics, which were deposited by atomic layer deposition on glass substrates at 200 °C. As characterized with single gate (SG), DG, and ground plane (GP) modes, our ZnO TFTs are well operated under 5 V. DG-mode TFT showed a field mobility of 0.38 cm²/V · s, a high saturation current of 6 μA, and an on/off current ratio of ∼10⁶, while SG- and GP-mode TFTs showed a similar value of mobility but with lower current. Using DG and GP modes, nor gate operation was well demonstrated.
