Abstract:
1. A semiconductor device, said device comprising: a) an interposer having two major surfaces wherein the first surface includes patterned metal conductors and bond pads and the second surface includes an array of solder balls; b) a semiconductor chip having a top surface and a back surface, said back surface of said chip adjacent said interposer, and said top surface comprising a plurality of terminals; c) a layer of polymeric material disposed on said first surface of the interposer comprising an insulator layer adjacent said interposer, and a metal filled polymer layer on said insulator layer, covering the area of the interposer over the solder ball array, at least a portion of said polymeric material layer between said chip and said interposer; and d) a plurality of electrical connections between said chip terminals and said bond pads on the interposer.
