Patent ID: 8907341

Claim:
A thin-film semiconductor device, comprising: a substrate; a semiconductor device; and a capacitor, wherein the semiconductor and the capacitor are above the substrate and apart from each other, the semiconductor device includes: a first gate electrode comprising a light-transmitting conductive material above the substrate; a second gate electrode comprising a light-shielding conductive material above the first gate electrode; a first insulating layer above the second gate electrode; a semiconductor layer above the first insulating layer; a second insulating layer above the semiconductor layer; and a source electrode and a drain electrode that are above the second insulating layer, the capacitor includes: a first capacitor electrode comprising a light-transmitting conductive material above the substrate; a dielectric layer comprising a same material as the first insulating layer, above the first capacitor electrode; and a second capacitor electrode above the dielectric layer, comprising a conductive material same as at least one of the source electrode and the drain electrode, overlapping at least part of the first capacitor electrode in a top view, and the second gate electrode, the semiconductor layer, and the second insulating layer have outlines that are coincident with one another in a top view.
