A solder bump structure and method for forming the same. The structure includes (a) a dielectric layer including a dielectric layer top surface (b) an electrically conductive bond pad on and in direct physical contact with the dielectric layer top surface; (c) a patterned support/interface layer on the dielectric layer top surface and thicker than the electrically conductive bond pad in the reference direction, wherein the patterned support/interface layer includes a hole and a trench, wherein the hole is directly above the electrically conductive bond pad, and wherein the trench is not filled by any electrically conductive material; and (d) an electrically conductive solder bump filling the hole and electrically coupled to the electrically conductive bond pad. |
