Claim Text:
1. A method of fabricating a nano-scale printing device, comprising: forming first interconnection lines on a substrate; forming a first interlayered dielectric layer on the first interconnection lines; forming second interconnection lines on the first interlayered dielectric layer to cross the first interconnection lines, the second interconnection lines having ring-shaped electrodes overlapped with the first interconnection lines; forming a second interlayered dielectric layer on the second interconnection line and the first interlayered dielectric layer; removing the second interlayered dielectric layer in the ring-shaped electrode and the first interlayered dielectric layer below the second interlayered dielectric layer to form holes partially exposing the first interconnection lines; and forming wedge-shaped electrodes on the first interconnection lines and in the holes.
