Abstract:
A method of forming a capacitor comprising:forming a layer of material over a substrate, the layer of material having a generally planar outer surface;forming a capacitor storage node having an uppermost surface, the storage node to be received within the layer of material and to have an upper surface elevationally below the generally planar outer surface;forming an overlying insulative material over the uppermost surface, the forming of the insulative material comprising forming a sufficient amount of the insulative material over the storage node to have an insulative material surface which is generally coplanar with the generally planar outer surface of the layer of material;after forming the capacitor storage node and the overlying insulative material, forming a capacitor dielectric functioning region discrete from the overlying insulative material operably proximate at least a portion of the capacitor storage node; andforming a cell electrode layer over the capacitor dielectric functioning region and the overlying insulative material.
