Abstract
A method includes growing an epitaxial layer over a substrate, forming a plurality of gates in the epitaxial layer, forming a breakdown voltage enhancement and leakage prevention structure in the epitaxial layer comprising a body ring structure, forming a source and a body region in the epitaxial layer, forming an interlayer dielectric layer over the epitaxial layer, forming a gate-source Electrostatic Discharge (ESD) diode structure in the interlayer dielectric layer, forming a source contact connected to the source, and a first terminal of the gate-source ESD diode structure, forming a gate contact connected to the plurality of gates and a second terminal of the gate-source ESD diode structure, and forming a drain contact underneath the substrate.
