Abstract
Disclosed is a Schottky barrier diode which may be applied to an application that requires a low off current (Ioff), such as a mobile integrated circuit. The Schottky barrier diode can improve a blocking characteristic for a backward current flow while maintaining an advantage of a turn-on current, by improving the structure of a contact surface that is pinched off by depletion.
