Abstract:
1. A flexible semiconductor device comprising: an insulating film; and a semiconductor device on the insulating film, wherein the insulating film includes an upper wiring pattern layer on an upper surface thereof and a lower wiring pattern layer on a lower surface thereof, wherein the semiconductor device comprises a semiconductor layer on the upper surface of the insulating film, a source electrode and a drain electrode on the upper surface of the insulating film so as to be in contact with the semiconductor layer, and a gate electrode on the lower surface of the insulating film so as to be opposed to the semiconductor layer, wherein an upper surface of the gate electrode protrudes toward the semiconductor layer beyond an upper surface of the lower wiring pattern layer so that a thickness of the gate electrode is larger than a thickness of the lower wiring pattern layer, and wherein, in the insulating film, a first film thickness of the insulating film opposes the source electrode, the drain electrode, the upper wiring pattern layer, and the lower wiring pattern layer is thicker than a second film thickness of the insulating film disposed between the gate electrode and the semiconductor layer.
