Abstract
A Schottky barrier diode includes a semiconductor substrate, an ohmic electrode formed on a first region of the semiconductor substrate, and a Schottky metal electrode formed on a second region spaced apart from the first region on the semiconductor substrate. The Schottky electrode includes at least one ohmic portion forming an ohmic contact with the semiconductor substrate, whereby rectifying characteristics of the Schottky barrier diode are improved.
