Abstract:
1. An organic thin film transistor, comprising: a substrate; a gate electrode on the substrate; an organic insulating layer on the substrate, the organic insulating layer comprising an organic polymer material; source and drain electrodes, each including (a) a first layer comprising at least one of nickel (Ni) and copper (Cu) formed as a single layer by electroless plating directly on only a surface of the organic insulating layer, and (b) a second layer comprising a metal material, the second layer being formed by electroless plating as a separate layer over the first layer such that all top and side surfaces of the first layer are covered by the metal material of the second layer; and an organic semiconductor layer comprising an organic semiconductor material in a region between the source electrode and the drain electrode, wherein,
