Abstract: A novel 30-nm gate-all-around (GAA) polycrystalline-silicon (poly-Si) nanowire (NW) thin-film transistor (TFT) is reported for the first time. Owing to the NW and GAA structure, the channel electric potential is well controlled by the gate electrode. After NH(3) plasma treatment for defects passivation, the values of 0.97 V, 224 mV/dec., and 0.895 V/V of threshold voltage, subthreshold swing, and drain-induced barrier lowering are achieved, respectively. A high driving current of 459 mu A/mu m and an ON-state/OFF-state current ratio of 5 x 10(7) are also obtained. These excellent characteristics indicate that the ultrasmall GAA NW poly-Si TFT would have the potential to be applied in the 3-D integrated-circuit or system-on-panel field.
