An integrated circuit comprising stacked capacitor memory cells having sub-lithographic, edge-defined word lines and a method for forming such an integrated circuit. The method forms conductors adjacent to sub-lithographic word lines in order to couple a stacked capacitor to the access transistor of the memory cell. The conductors are bounded by the word lines. The bit line and capacitor are formed with a single mask image in such a manner as to self-align the bit line and the capacitor and to maximize the capacitance of the memory device. The method may be used to couple any suitable circuit element to a semiconductor device in an integrated circuit having edge-defined, sub-lithographic word lines.
