    摘要: Provided are a Schottky barrier tunnel transistor (SBTT) and a method of fabricating the same. The SBTT includes a buried oxide layer formed on a base substrate layer and having a groove at its upper surface; an ultra-thin silicon-on-insulator (SOI) layer formed across the groove; an insulating layer wrapping the SOI layer on the groove; a gate formed to be wider than the groove on the insulating layer; source and drain regions each positioned at both sides of the gate, the source and drain regions formed of silicide; and a conductive layer for filling the groove. In the SBTT, the SOI layer is formed to an ultra-thin thickness to minimize the occurrence of a leakage current, and a channel in the SOI layer below the gate is completely wrapped by the gate and the conductive layer, thereby improving the operational characteristics of the SBTT.
