Abstract:
1. A method of forming a capacitor and contact structures, the method comprising: providing a structure with open above a lower electrode of the capacitor to expose a non-conductive layer over the lower electrode, the structure including a conductive structure offset from the lower electrode; providing a conformal layer of conductive material above the conductive structure, and within the opening, above the lower electrode of the capacitor; patterning and etching the layer of conductive material to define from the layer of conductive material a conductive material hard mask and an upper electrode of the capacitor, the conductive material hard mask being disposed at least partially above the conductive structure, and the upper electrode being disposed above the lower electrode, within the opening above the lower electrode; and forming a first conductive contact structure and a second conductive contact structure, the first conductive contact structure extending through an opening in the conductive material hard mask and conductively contacting the conductive structure, and the second conductive contact structure conductively contacting one of the lower electrode of the capacitor or the upper electrode of the capacitor.
