An improved Schottky device, having a low resistivity layer of semiconductor material, a high resistivity layer of semiconductor material and a buried dopant region positioned in the high resistivity layer utilized to reduce reverse leakage current. The low resistivity layer can be an N<+ >material while the high resistivity layer can be an N<- >layer. The buried dopant region can be of P<+ >material, thus forming a PN junction with an associated charge depletion zone in the N<- >layer and an associated low reverse leakage current. The location of the P<+ >material allows for a full Schottky barrier between the N<- >material and a barrier metal to be maintained, thus the device experiences a low forward voltage drop.
