Abstract:
1. A method of manufacturing a semiconductor device, comprising: providing a prefabricated integrated passive device (IPD) by, providing a sacrificial substrate; forming a first insulation layer over the sacrificial substrate; forming a first conductive layer over the first insulating layer; forming a plurality of conductive pillars over the first conductive layer and directly connected to the first conductive layer; after forming the conductive pillars, mounting the prefabricated IPD to the first conductive layer such that the prefabricated IPD is disposed between the conductive pillars, the prefabricated IPD being self-aligned to the first conductive layer; mounting a discrete capacitor having a value greater than one nanofarad over the first conductive layer, the discrete capacitor being electrically connected to one of the conductive pillars; forming an encapsulant around the prefabricated IPD, discrete capacitor, and conductive pillars; forming a second insulation layer over the encapsulant; forming a second conductive layer over the second insulating layer, the second conductive layer being electrically connected to the conductive pillars; and removing the sacrificial substrate.
