description Disclosed herein are various methods of forming semiconductor devices that have capacitor and via contacts. In one example, the method includes forming a first conductive structure and a bottom electrode of a capacitor in a layer of insulating material, forming a layer of conductive material above the first conductive structure and the bottom electrode and performing an etching process on the layer of conductive material to define a conductive material hard mask and a top electrode for the capacitor, wherein the conductive material hard mask is positioned above at least a portion of the first conductive structure. This illustrative method includes the further steps of forming an opening in the conductive material hard mask and forming a second conductive structure that extends through the opening in the conductive material hard mask and conductively contacts the first conductive structure.
