发明名称 Methods of forming semiconductor devices having capacitor and via contacts
摘要 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.
