This study proposes an oxide thin-film transistor (TFT) structure that enables signal input from the backside of the polyimide film substrate using three-dimensional wires that penetrate the substrate. TFTs with channel lengths down to 3 μm exhibit clear switching behavior with an on/off current ratio of over 10⁷.
