Abstract:
1. A Schottky barrier tunnel single electron transistor comprising: an insulating layer formed on a substrate; a semiconductor layer formed on a predetermined region of the insulating layer, and having a channel region for a quantum dot of a single electron transfer and source and drain regions separated from each other, wherein at least portions of the source and drain regions are silicided with predetermined metal to make a Schottky junction with the channel region; a gate insulating layer and a gate electrode sequentially formed on the channel region; a sidewall insulating layer formed at both sidewalls of the gate insulating layer and the gate electrode; an interlayer insulating layer pattern formed on the entire surface of the resultant structure to expose a portion of the gate electrode and portions of the source and drain regions; and a metal interconnection formed on the exposed gate electrode and source and drain electrodes.
