Abstract:
A method of manufacturing a radiation detector having a plurality of detector cell contacts on a first surface of a semiconductor radiation detector substrate at positions for defining radiation detector cells and a layer of conductive material on a second surface of said substrate opposite to said first surface, said substrate being formed from cadmium zinc telluride or cadmium telluride semiconductor material, and said cell contacts and said layer of conductive material being on said first and second surfaces, respectively of said semiconductor material, wherein said method includes steps of forming said contacts on said first surface including steps of:(a) forming a layer of aluminum nitride passivation material on said first surface of said substrate with openings to said substrate surface at said contact positions;(b) applying metal over said layer and said openings; and(c) removing metal overlying said layer to separate individual detector cell contacts.
