A Schottky barrier diode comprises a doped guard ring having a doping of a second conductivity type in a semiconductor-on-insulator (SOI) substrate. The Schottky barrier diode further comprises a first-conductivity-type-doped semiconductor region having a doping of a first conductivity type, which is the opposite of the second conductivity type, on one side of a dummy gate electrode and a Schottky barrier structure surrounded by the doped guard ring on the other side. A Schottky barrier region may be laterally surrounded by the dummy gate electrode and the doped guard ring. The doped guard ring includes an unmetallized portion of a gate-side second-conductivity-type-doped semiconductor region having a doping of a second conductivity type. A Schottky barrier region may be laterally surrounded by a doped guard ring including a gate-side doped semiconductor region and a STI-side doped semiconductor region. Design structures for the inventive Schottky barrier diode are also provided.
