Abstract:
1. A method of making a semiconductor device, comprising: providing a temporary carrier for supporting the semiconductor device; forming an integrated passive device (IPD) structure over the temporary carrier, the IPD structure including an inductor, resistor, or capacitor; forming a plurality of first conductive posts over the temporary carrier; mounting a first semiconductor die to the IPD structure with a flipchip interconnect; depositing a first wafer molding compound over the first conductive posts and first semiconductor die; bonding a core structure to the first conductive posts over the first semiconductor die, the core structure including a silicon material; forming conductive through silicon vias (TSVs) in the core structure; forming a first redistribution layer over the core structure; forming a plurality of second conductive posts over the core structure; mounting a second semiconductor die over the semiconductor device with a flipchip interconnect, the second semiconductor die being electrically connected to the core structure; depositing a second wafer molding compound over the second conductive posts and second semiconductor die; and forming a second redistribution layer over the second molding compound and second semiconductor die.
