Abstract

System and method for providing a multiple die interposer structure. An embodiment comprises a plurality of interposer studs in a molded interposer, with a redirection layer on each side of the interposer. Additionally, the interposer studs may be initially attached to a conductive mounting plate by soldering or wirebond welding prior to molding the interposer, with the mounting plate etched to form one of the redirection layers. Integrated circuit dies may be attached to the redirection layers on each side of the interposer, and interlevel connection structures used to mount and electrically connect a top package having a third integrated circuit to the interposer assembly.
