PIXEL WITH SPATIALLY VARYING SENSOR POSITIONS

摘要

PROBLEM TO BE SOLVED: To provide a reduced shadowing in an imaging element array.;SOLUTION: An image sensor including a substrate, at least one metal layer (474), and a plurality of pixels (432) arranged in an array (30). Each pixel includes a sense element (530) disposed in the substrate and at least one metal interconnect segment disposed in the at least one metal layer. The array includes a pair of perpendicular axes (436, 438) extending from an optical center (439). For a line (434) of pixels extending perpendicularly from one of the axes to a peripheral edge of the array, a spacing (524) between the sense elements of consecutive pairs of pixels (432a, 432b) of the line is at least equal to a spacing (526) between the associated at least one metal interconnect segment (456a, 456b), and for at least one consecutive pair of pixels of the line, the spacing between the sense elements is greater by an incremental amount than the spacing between the corresponding at least one metal interconnect segment.;COPYRIGHT: (C)2007,JPO&INPIT
