A semiconductor power device includes an active region configured to conduct current when the semiconductor device is biased in a conducting state, and a termination region along a periphery of the active region. The termination region includes a first silicon region of a first conductivity type extending to a first depth within a second silicon region of a second conductivity type, the first and second silicon regions forming a PN junction therebetween. The second silicon region has a recessed portion extending below the first depth and out to an edge of a die housing the semiconductor power device. The recessed portion forms a vertical wall at which the first silicon region terminates. A first conductive electrode extends into the recessed portion and is insulated from the second silicon region.
