Abstract:
An interconnection element and method for making same is disclosed. The interconnection element may include a plurality of metal conductors, a plurality of solid metal bumps and a low melting point (LMP) metal layer. The solid metal bumps overly and project in a first direction away from respective ones of the conductors. Each bump has at least one edge bounding the bump in at least a second direction transverse to the first direction. The low melting point (LMP) metal layer has a first face joined to the respective ones of the conductors and bounded in the second direction by at least one edge and a second face joined to the bumps. The edges of the bumps and the LMP layer are aligned in the first direction, and the LMP metal layer has a melting temperature substantially lower than the conductors.
