The present disclosure, in some embodiments, relates to a semiconductor package. The semiconductor package includes an interposer substrate laterally surrounding through-substrate-vias. A redistribution structure is on a first surface of the interposer substrate. The redistribution structure laterally extends past an outermost sidewall of the interposer substrate. A packaged die is bonded to the redistribution structure. One or more conductive layers are arranged along a second surface of the interposer substrate opposite the first surface. A molding compound vertically extends from the redistribution structure to laterally surround the one or more conductive layers.
