INTEGRATED CIRCUIT PACKAGE USING POLYMER-SOLDER BALL STRUCTURES AND FORMING METHODS
A conductive polymer-solder ball structure is provided. The conductive polymer-solder ball structure includes a wafer having at least one metal pad providing an electrical conductive path to a substrate layer, a conductive polymer pad located directly on the wafer over the at least one metal pad, an electrolessly plated layer located on a surface of the conductive polymer pad, and a solder ball located on a surface of the electrolessly plated layer.
