摘要: Structures and methods to reduce maximum current density in a solder ball are disclosed. A method includes forming a contact pad in a last wiring level and forming a plurality of wires of the contact pad extending from side edges of the contact pad to respective ones of a plurality of vias. Each one of the plurality of wires has substantially the same electrical resistance.
