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 16):
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 a contact hole in the insulating layer, through which a portion of an upper surface of the metal oxide layer is exposed; (G) 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; (H) forming another insulating layer that covers the insulating layer and the second electrode and is in contact, in the contact hole, with another portion of the region of the metal oxide layer that is exposed through the contact hole; and (I) forming a third electrode on the other insulating layer.
