Provided is a method for manufacturing a nano-gap electrode device
comprising the steps of: forming a first electrode on a substrate;
forming a spacer on a sidewall of the first electrode; forming a second
electrode on an exposed substrate at a side of the spacer; and forming a
nano-gap between the first electrode and the second electrode by removing
the spacer, whereby it is possible to control the nano-gap position,
width, shape, and etc., reproducibly, and manufacture a plurality of
nano-gap electrode devices at the same time.
