Abstract:
A semiconductor device includes a TFT ( 101 ), the TFT including a gate electrode ( 12 ), a gate insulating layer ( 14 ) covering the gate electrode, a metal oxide layer ( 16 A) including a channel region ( 16 c ), a source contact region ( 16 s ) and a drain contact region ( 16 d ), a first electrode ( 18 A) in contact with the source contact region, an insulating layer ( 22 ) formed on the metal oxide layer and the first electrode, the insulating layer having a first opening ( 22 p ) therein through which a portion of the metal oxide layer is exposed, and a light-transmissive second electrode ( 24 ) formed on the insulating layer and in a contact hole including the first opening, wherein the second electrode ( 24 ) is in contact with the drain contact region ( 16 d ) in the contact hole, the drain contact region ( 16 d ) is a portion of a region ( 17 ) of the metal oxide layer ( 16 A) that is exposed through the contact hole, and as seen from a direction normal to a substrate ( 11 ), the second electrode ( 24 ) does not overlap the channel region ( 16 c ).

Claim (Index 20):
A method for manufacturing a semiconductor device, comprising the steps of:\n (a) forming a gate electrode and a gate line on a substrate; (b) forming a gate insulating layer covering the gate electrode and the gate line; (c) forming an oxide semiconductor film on the gate insulating layer and patterning the oxide semiconductor film, thereby obtaining a metal oxide layer; (d) forming a first electrode in contact with a portion of an upper surface of the metal oxide layer; (e) forming an insulating layer covering the metal oxide layer and the first electrode; (f) forming another light-transmissive electrode on the insulating layer; (g) forming another insulating layer so as to cover the insulating layer and the other electrode; (h) etching the insulating layer and the other insulating layer, thereby forming a contact hole through which a portion of an upper surface of the metal oxide layer is exposed; and (i) forming a light-transmissive second electrode on the insulating layer and in the contact hole, wherein the second electrode is in contact, in the contact hole, with a portion of a region of the metal oxide layer that is exposed through the contact hole.
