Abstract:
1. An imaging sensor comprising: a plurality of substrates comprising a first substrate and at least one second, subsequent supporting substrate; a pixel array; a plurality of interconnects; a plurality of supporting circuits; and a plurality of pixel read buses and circuit buses; wherein the first substrate of the plurality of substrates comprises the pixel array; wherein the plurality of supporting circuits are disposed on the at least one second, subsequent supporting substrate that is disposed remotely relative to said first substrate; wherein said plurality of supporting circuits are electrically connected to, and in electrical communication with, said pixel array via the plurality of interconnects disposed between said first substrate and said at least one second, subsequent supporting substrate; wherein the pixel array comprises a plurality of pixel groups with one pixel read bus per pixel group; wherein each of the plurality of interconnects reads out a pixel group to one of the circuit buses; wherein the plurality of supporting circuits further comprise a plurality of readout supporting circuits with one circuit bus per readout supporting circuit; wherein each pixel read bus and each circuit bus are superimposed; wherein at least one interconnect provides an electrical connection between each pixel read bus and each circuit bus; wherein each of the plurality of interconnects is placed anywhere along a path of the superimposed pixel read bus for each pixel group and the circuit bus for each readout supporting circuit; wherein said plurality of interconnects are spaced relative to one another at a distance that is greater than a pixel pitch of said pixel array.
