Abstract:
1. A method of making a semiconductor device, comprising: providing a carrier for supporting the semiconductor device; mounting a first semiconductor die over the carrier; mounting a first dummy die having a first through-silicon via (TSV) over the carrier; encapsulating the first semiconductor die and the first dummy die using a wafer molding material; removing the carrier; forming a first redistribution layer (RDL) over a first surface of the first semiconductor die and a first surface of the first dummy die to electrically connect the first TSV and a contact pad of the first semiconductor die; forming an insulation layer over the first RDL; forming a second RDL over a second surface of the first dummy die opposite the first surface of the first dummy die and electrically connected to the first TSV; and connecting a semiconductor package to the second RDL.
