Abstract:
1. An organic transistor comprising: an insulating substrate; a pair of insulating pedestals arranged spaced apart from each other on the insulating substrate and forming respectively raised flat surfaces; a source electrode provided on the raised flat surface formed on one of the pedestals; a drain electrode provided on the raised flat surface formed on the other pedestal; a gate electrode provided on the insulating substrate between the pair of pedestals; and an organic semiconductor layer arranged in contact with an upper surface of the source electrode and an upper surface of the drain electrode, wherein the gate electrode and a lower surface of the organic semiconductor layer oppose each other vertically across a gap region, and side surfaces of the pedestals facing the gap region are shaped such that the side surfaces increase in distances in a horizontal direction from the gate electrode with decreasing height from upper side edges toward lower side edges of the side surfaces.
