Schottky device and method of forming

摘要

A conductive layer includes a first portion that forms a Schottky region with an underlying first region having a first conductivity type. A second region of a second conductivity type underlies the first region, where the second conductivity type is opposite the first conductivity type. A third region of the first conductivity type immediately underlies the second region and is electrically coupled to a cathode of the device.
