Abstract:
1. A method of making a semiconductor radiation detector comprising: providing a semiconductor substrate having substantially planar upper and lower opposing surfaces having first and second surface areas respectively, said first and second surface areas being defined by prospective dice lines; forming a first metal layer on said substantially planar upper surface such that said first metal layer will have a surface area less than said first surface area of said substantially planar upper surface as defined by spaces on said substantially planar upper surface between said first metal layer and said prospective dice lines which define said first surface area; forming a second metal layer on said substantially planar lower opposing surface; and dicing said semiconductor substrate through said prospective dice lines to produce a semiconductor radiation detector having substantially planar upper and lower opposing surfaces wherein said planar upper opposing surface is of a third surface area substantially similar to said surface layer of said first metal layer, said semiconductor radiation detector further including substantially perpendicular side walls.
