Abstract:
1. A semiconductor device comprising: a substrate having a pixel portion and a driver circuit portion; a first conductive film over the substrate; a first insulating film over the first conductive film; a thin film transistor over the first insulating film; a second insulating film over the thin film transistor; a capacitor over the second insulating film, the capacitor comprising a lower conductive layer and an upper conductive layer; a third insulating film over the capacitor, the third insulating film having a planarized surface; a pixel electrode on the third insulating film and the upper conductive layer, the pixel electrode electrically connected to the thin film transistor; and an electrode in the driver circuit portion, the electrode comprising a same material of the pixel electrode, wherein the first conductive film is electrically connected with the thin film transistor, and wherein the third insulating film has an opening portion for connecting the pixel electrode and the upper conductive layer of the capacitor.
