Abstract:
1. A semiconductor device, comprising: a first semiconductor chip having at least one electrically conductive contact at a first side of the first semiconductor chip; an extension layer extending laterally from one or more sides of the first semiconductor chip; a redistribution layer disposed on a surface of the extension layer and the first side of the first semiconductor chip, the redistribution layer electrically coupling the at least one electrically conductive contact of the first semiconductor chip to at least one electrical connector; and an interposer electrically coupled to the at least one electrical connector and having a plurality of electrically conductive contacts at a surface of the interposer facing away from the redistribution layer; and a ball grid array disposed on the plurality of electrically conductive contacts of the interposer, wherein the at least one electrical connector comprises a plurality of copper pillars disposed between the redistribution layer and the interposer.
