Abstract
A solid-state image sensor includes semiconductor substrate having element forming pixel array and element forming peripheral circuit, and wiring structure. The wiring structure includes electrically conductive pattern arranged in trench of interlayer insulation film and includes primary lines parallel to first direction and auxiliary lines connecting the primary lines. Width of primary line in second direction perpendicular to the first direction is not less than 250 nm and not more than 2,000 nm, interval between adjacent primary lines is not more than 500 nm, width of the auxiliary line in the first direction is less than 400 nm. Value obtained by dividing area of the electrically conductive pattern in square region by area of the square region is not more than 0.9.
