Abstract:
A structure representative of a conductive interconnect of a microelectronic element is provided, which may include a conductive metallic plate having an upper surface, a lower surface, and a plurality of peripheral edges extending between the upper and lower surfaces, the upper surface defining a horizontally extending plane. The structure may also include a lower via having a top end in conductive communication with the metallic plate and a bottom end vertically displaced from the top end. A lower conductive or semiconductive element can be in contact with the bottom end of the lower via. An upper metallic via can lie in at least substantial vertical alignment with the lower conductive via, the upper metallic via having a bottom end in conductive communication with the metallic plate and a top end vertically displaced from the bottom end. The upper metallic via may have a width at least about ten times than the length of the metallic plate and about ten times smaller than the width of the metallic plate. The structure may further include an upper metallic line element in contact with the top end of the upper metallic via.
