Abstract:
1. A semiconductor structure comprising: a through silicon via (TSV) extending through the semiconductor structure; an electrically conducting pad at a surface of the semiconductor structure, the TSV terminating in direct contact at a first side of the electrically conducting pad; a passivation layer covering the electrically conducting pad, the passivation layer having a plurality of openings exposed to the electrically conducting pad, the plurality of openings extending entirely through the passivation layer to expose the electrically conducting pad through the plurality of openings; and a plurality of electrically conducting structures formed in the plurality of openings and in direct contact with a second side of the electrically conducting pad, the second side of the electrically conducting pad being opposite the first side of the electrically conducting pad, the plurality of electrically conducting structures in direct contact with the electrically conducting pad being offset with respect to the TSV in direct contact with the electrically conducting pad.
