Abstract:
1. A semiconductor device having a plurality of thin film transistors, each of the plurality of thin film transistors having: a gate electrode over a substrate; an active layer comprising a semiconductor film over said gate electrode, the active layer having at least a channel forming region, source and drain regions, LDD regions, and end portions; an insulating film over said active layer and having at least one opening, said opening located so as not to overlap with said gate electrode; and an electrode on said insulating film, said electrode connected to one of said source and drain regions through said opening, wherein said electrode is located so as to cover one of the end portions of said active layer with said insulating film interposed therebetween, and wherein inner boundaries of said opening are aligned with boundaries of said one of said source and drain regions connected with said electrode and one of said LDD regions extends to surround said one of the said source and drain regions.
