Abstract:
1. An active device, comprising: a source comprising a plurality of first stripe electrodes parallel to each other and a first connection electrode connected to the first stripe electrodes; a drain comprising a plurality of second stripe electrodes parallel to each other and a second connection electrode connected to the second stripe electrodes, wherein the first stripe electrodes and the second stripe electrodes are parallel to each other and alternately arranged between the first connection electrode and the second connection electrode, and the source and the drain are electrically isolated and a zigzag trench is formed therebetween; an oxide semiconductor layer in contact with the source and the drain, wherein a contact area between the oxide semiconductor layer and each first stripe electrode equals to a layout area of each first stripe electrode, and wherein a contact area between the oxide semiconductor layer and each second stripe electrode equals to a layout area of each second stripe electrode; a gate extending along the zigzag trench; and a gate insulator layer disposed between the gate and the oxide semiconductor layer.
