A semiconductor structure includes a semiconductor substrate, formed on which are a first layer and a second layer, and an alignment-control mask. The alignment-control mask includes a first direction reference element, formed in a first region of the first layer and extending in a first alignment direction, and first position reference elements, formed in a first region of the second layer that corresponds to the first region of the first layer accommodating the first direction reference element. The first position reference elements are arranged in succession in the first alignment direction and in respective staggered positions with respect to a second alignment direction perpendicular to the first alignment direction. |
