A method of fabricating a single electron tunneling (SET) device, the method including forming a source electrode and a drain electrode a predetermined distance apart from each other on an insulating substrate, forming a metal layer having a thickness on the order of nanometers between the source and drain electrodes, and forming quantum dots between the source and drain electrodes due to the movement of metal atoms/ions within the metal layer caused by applying a predetermined voltage to the source and drain electrodes. In the manufacture of an SET device, quantum dots can be formed by a simple method instead of an self assembled monolayer (SAM) method or lithographic methods. Thus, SET devices fabricated in this way have no material dependency, and are also applicable to large scale integration (LSI) structures. Also, since quantum dots are obtained by deposition and electromigration, SET devices having the above-described advantages can be mass-produced.
