Abstract
An ESD protection diode in a semiconductor device includes: a semiconductor substrate; a diode group that has a plurality of grouped VNW diodes, each of the VNW diodes having a VNW having a lower end and an upper end, that are formed on the semiconductor substrate and have a semiconductor material; and a top plate that is formed above the diode group and is a conductive layer electrically connected to the upper ends of the VNWs of the respective VNW diodes, and there is fabricated the semiconductor device that is capable of, even when large current flows through the VNW diode, suppressing current concentration and preventing damage of the VNW diode.
