Abstract:
A storage capacitor structure on a substrate, comprising:a first capacitor electrode over the substrate; a capacitor dielectric layer over the first capacitor electrode; a second capacitor electrode over the capacitor dielectric layer, wherein the first capacitor electrode, the capacitor dielectric layer and the second capacitor electrode together form the storage capacitor; a passivation layer over the second capacitor electrode, wherein the passivation layer has an opening that exposes a portion of the second capacitor electrode; and a pixel electrode layer over the passivation layer, wherein the pixel electrode layer has a protruding section, and the second capacitor electrode and the pixel electrode layer are electrically connected using the protruding section through the opening in the passivation layer, and wherein when the first capacitor electrode comes in electrical contact with the second capacitor electrode, the protruding section can be cut so that the pixel electrode layer can serve as an upper capacitor electrode of the storage capacitor.
