Abstract

A semiconductor device includes a gate structure formed on a substrate in which an LDD structure is formed, wherein gate structure includes a Schottky electrode making a Schottky contact with a channel region in the substrate, a low-resistance layer provided above the Schottky electrode, and a stress-relaxation layer interposed between the Schottky electrode and the stress-relaxation layer. The low-resistance layer and said stress-relaxation layer form an overhang structure with respect to the Schottky electrode.
