Abstract
A vertical semiconductor rectifier device includes a semiconductor substrate of first conductivity type and having a plurality of gates insulatively formed on a first major surface and a plurality of source/drain regions of the first conductivity type formed in surface regions of second conductivity type in the first major surface adjacent to the gates. A plurality of channels of the second conductivity type each abuts a source/drain region and extends under a gate.
