Abstract:
A semiconductor processing method of forming a stacked container capacitor, comprising:forming an electrically conductive material over a substrate, the conductive material having a first outer surface;forming an insulative material over the conductive material;etching a container opening through the insulative material to outwardly expose only a portion of the conductive material first outer surface;etching the exposed portion of the conductive material to define a conductive material second outer surface which is closer to the substrate than the conductive material first outer surface and to deepen the container opening;providing an electrically conductive storage node container layer within the container opening and over the second outer conductive material surface;providing a capacitor dielectric layer over the capacitor storage node layer; andproviding an electrically conductive outer capacitor plate over the capacitor dielectric layer.
