Abstract
A semiconductor junction device includes a substrate of low resistivity semiconductor material having a preselected polarity. A tapered recess extends into the substrate and tapers inward as it extends downward from an upper surface of the substrate. A semiconductor layer is disposed within the recess and extends above the upper surface of the substrate. The semiconductor layer has a polarity opposite from that of the substrate. A metal layer overlies the semiconductor layer.
