Abstract:
1. A semiconductor device comprising: a thin film transistor formed over a substrate; an insulating film including silicon, nitrogen, and oxygen formed over the thin film transistor; a conductive layer formed on and in contact with the insulating film; a connection wiring formed on and in contact with the conductive layer; and a capacitor comprising a first electrode, a second electrode over the first electrode, and a third electrode over the second electrode, wherein the connection wiring is electrically connected to an active region of the thin film transistor through a contact hole formed in the conductive layer, the insulating film and a gate insulating film of the thin film transistor, wherein a first dielectric layer between the first electrode and the second electrode is the gate insulating film, wherein a second dielectric layer between the second electrode and the third electrode is the insulating film, wherein the conductive layer is formed from a first conductive layer, wherein the connection wiring is formed from a second conductive layer, and wherein the third electrode is formed from the first conductive layer and the second conductive layer.
