Abstract: A method for manufacturing a semiconductor device and a semiconductor device manufactured using the same are provided to form a semiconductor device to which a metal silicide is adopted without a space structure by forming a gate electrode with a conductive compound. A gate dielectric is formed on a substrate(10). A conductive compound, which is not reacted with a metal layer to be formed through a subsequent process, is formed on the gate dielectric. The conductive compound and the gate dielectric are etched to form a gate electrode(12A). The metal layer is formed on a top of the substrate including the gate electrode. The metal and silicon contained in the substrate are reacted to form a source and drain region(14) comprised of a metal silicide layer on the substrate exposed at both sides of the gate electrode. After forming the metal silicide layer, the remaining metal layer which is not reacted with the silicon is removed.

Abstract: A schottky barrier tunnel transistor is provided to form a stable high-performance N-type schottky barrier tunnel transistor with a low schottky barrier with respect to electrons by forming a schottky junction on the (111) surface of a silicon by an anisotropic etch process. An insulation layer(20) is deposited on a substrate(10). A source/drain(30a,30b) is formed on the insulation layer. A channel(90) is formed between the source and the drain. A gate insulation layer(40) and a gate electrode(60) are sequentially formed on the channel. A sidewall insulation layer(50) is formed on both sidewalls of the gate insulation layer and the gate electrode. The interface of one of the source or drain and the channel has a (111) surface of silicon, and at least a part of the source/drain including the silicon (111) surface is silicidized by a predetermined metal material to be a schottky junction. The channel can be higher than the source/drain so that the interface has a slope.
