Abstract:
1. An electronic device comprising: a substrate; a number of conductive bond pads on the substrate and configured to electrically contact one or more integrated circuits; and a number of bump units over the substrate, wherein each of the bump units includes: an electrically insulating bump-forming body disposed at least partially over one or more of the conductive bond pads and extending longitudinally in a first direction in a greater amount than a second direction, wherein a portion of the one or more of the conductive bond pads is vertically aligned and disposed under a width of the bump-forming body; at least two conductive layers separated from each other and disposed on the electrically insulating bump-forming body such that the electrically insulating bump-forming body rests between the substrate and the at least two conductive layers, the at least two conductive layers extending longitudinally in the second direction, wherein the second direction is orthogonal to the first direction; wherein the one or more of the conductive bond pads extend longitudinally in the second direction, wherein the electrically insulating bump-forming body includes a top surface, a first sidewall and a second sidewall, and wherein one of the at least two conductive layers extends from a point disposed on the top surface between the first and second sidewalls toward the substrate via one of the first sidewall or the second sidewall, wherein one of the at least two conductive layers has a greater width than the other of the at least two conductive layers, and wherein the first direction and the second direction are disposed on a plane coplanar with the substrate.
