Abstract
The present examples relate to a Schottky diode having floating guard rings and an additional element isolation layer configured to further improve a breakdown voltage of the Schottky diode, while maintaining the turn-on voltage and current in the forward characteristic, compared to a related Schottky diode. The floating guard rings in the examples are located in a position between the anode and the cathode regions or under the anode.
