Abstract
Electrostatic Discharge (ESD) protection using lateral surface Schottky diodes is disclosed. In one embodiment, a Metal-Insulator-Metal (MIM) capacitor with ESD protection comprises a group III-V substrate, a first metal layer contacting the substrate, an insulation layer formed over the first metal layer, and a second metal layer formed over the insulation layer and also contacting the substrate. A MIM capacitor is formed by overlapping portions of the first metal layer, the insulation layer, and the second metal layer. First and second Schottky diodes are formed where the first and second metal layers, respectively, contact the substrate, such that the cathodes of the Schottky diodes are electrically connected to one another and the anodes of the Schottky diodes are electrically connected to the respective overlapping portions of the first and second metal layers.
