Abstract:
1. A detector assembly having a plurality of pixels that include a sensor element coupled to a sensor input of an electronic processing circuit, the detector assembly comprising: at least one integrated circuit formed by stitching a plurality of reticles of at least two different types and having an array of electronic processing circuits each having a respective sensor input disposed toward a first surface of the wafer and accessible from the first surface via a terminal pad formed near an edge of the integrated circuit such that each terminal pad serves to access multiple sensor inputs via a controller fabricated at an edge of the wafer; sensor elements disposed on the first surface of the at least one integrated circuit in said detector assembly whereby an exposed surface of the sensor elements forms a common first electrode towards which incident photons are directed, and an opposite unexposed surface thereof forms multiple second electrodes of opposite polarity to the first electrode each in registration with a corresponding sensor input; a plurality of rectangular IC modules each fabricated on a very large area CMOS wafer and having a major edge and a minor edge, the major edge having a dimension (L) that is substantially half of a width of the detector, the IC module having at least one array of electronic processing circuits each electronic processing circuit having a respective sensor input disposed toward a first surface of the wafer and accessible from the first surface via a terminal pad formed towards a minor edge of the IC module such that each terminal pad serves to access multiple sensor inputs via a controller fabricated at an edge of the wafer; and multiple pairs of IC modules juxtaposed edge to edge so that respective minor edges of each of pair are juxtaposed with the respective terminal pads of each IC module disposed toward opposing outer non-contiguous edges of the detector and with adjacent pairs of IC modules being juxtaposed along their major edges; the sensor elements being disposed on the first surface of the respective IC modules in said detector assembly.
