Patent ID: 7741148

Claim:
A method of making a semiconductor device, comprising: providing a substrate; forming a first interconnect structure over a first side of the substrate by, (a) forming a first conductive layer over the first side of the substrate, (b) forming a first insulating layer over the first conductive layer and substrate, (c) removing a portion of the first insulating layer to expose the first conductive layer, (d) forming a second conductive layer over the first conductive layer, (e) forming a second insulating layer over the second conductive layer and first insulating layer, and (f) removing a portion of the second insulating layer to expose the second conductive layer; mounting a semiconductor die or component to the first interconnect structure; depositing an encapsulant over the semiconductor die or component and first interconnect structure; removing a portion of a second side of the substrate, opposite the first side of the substrate, to reduce its thickness; forming a through silicon via (TSV) through the second side of the substrate to the first interconnect structure; and forming a second interconnect structure over the TSV.
