Patent ID: 10096629

Abstract:
A semiconductor device (1001) includes a thin-film transistor (101) including a gate electrode (3), an oxide semiconductor layer (7), a gate insulating layer (5), a source electrode (9s), and a drain electrode (9d); a metal oxide layer (8) including a conductor region (70c) and formed from an oxide film from which the oxide semiconductor layer (7) is also formed; an interlayer insulating layer (13) covering the thin-film transistor and the metal oxide layer (8); and a transparent conductive layer (15) disposed on the interlayer insulating layer and electrically connected to the drain electrode, wherein the oxide semiconductor layer (7) and the metal oxide layer (8) contain indium, tin, and zinc, and the transparent conductive layer (15) overlaps at least a portion of the conductor region (70c) with the interlayer insulating layer (13) therebetween.
