Abstract

A semiconductor radiation detector having a semiconductor substrate and first and second metal layers. The semiconductor substrate has substantially planar upper and lower opposing surfaces which have respective first and second surface areas. The first and second surface areas are defined by prospective dice lines. The first metal layer is on the substantially planar upper surface such that the first metal layer will have a surface area less than the first surface area of the substantially planar upper surface as defined by spaces on the substantially planar upper surface between the first metal layer and the prospective dice lines which define the first surface area. The second metal layer is on the substantially planar lower opposing surface.
