Abstract:
A stacked die semiconductor package includes a leadframe including a die pad and lead terminals on at least two sides of the die pad, a top die having circuitry coupled to bond pads, and bottom die having a back side that is attached by die attach material to the die pad and a top side having at least one redistribution layer (RDL) over and coupled to a top metal level including connections to input/output (IO) nodes on the top metal level. The RDL provides a metal pattern including wirebond pads that match locations of the bond pads of the top die. The bond pads on the top die are flip-chip attached to the wirebond pads of the bottom die, and the bond wires are positioned between the wirebond pads and the lead terminals.
