Abstract
A Junction Barrier Schottky (JBS) diode includes an N-type epitaxial layer disposed on SiC substrate, P+ wavy regions are disposed in the epitaxial layer adjoining a top planar surface, each of which is separated from an adjacent one of the wavy regions by a Schottky barrier contact region. P+ island regions are disposed in the Schottky barrier contact regions. A top metal layer is disposed along the top planar surface in direct contact with the Schottky barrier contact regions, the P+ wavy regions, and the P+ island regions, the top metal layer comprising the anode of the JBS diode. A bottom metal layer is disposed beneath the SiC substrate. The bottom metal layer comprises the cathode of the JBS diode.
