Abstract:
1. A semiconductor device, comprising: a U-shaped semiconductor layer on a substrate; a gate electrode electrically insulated from the semiconductor layer by a gate insulating layer; an insulating layer on the gate insulating layer and on the gate electrode; and a source electrode and a drain electrode on the insulating layer, the source and drain electrode being connected to the semiconductor layer, the semiconductor layer, the gate electrode, the source electrode, and the drain electrode being configured to provide a plurality of thin film transistors connected in series or in parallel, the gate electrode being a common gate electrode to the plurality of thin film transistors, and the source electrode overlapping at least a part of the common gate electrode in each of the plurality of thin film transistors, wherein the source electrode, the insulating layer, and the common gate electrode overlap each other so as to provide a capacitor integrated with the thin film transistors, wherein: the U-shaped semiconductor layer comprises two legs with free ends, one of the free ends is interconnected with the drain electrode by one contact hole, and another one of the free ends is interconnected with the drain electrode by one contact hole and a base section of the semiconductor layer is contacted to the source electrode by three contact holes.
