Fully molded semiconductor structure with through silicon via (TSV) vertical interconnects

A method of making a semiconductor device may include providing a large semiconductor die comprising conductive interconnects with a first encapsulant disposed over four side surfaces of the large semiconductor die, over the active surface of the large semiconductor die, and around the conductive interconnects. A first build-up interconnect structure may be formed over the large semiconductor die and over the first encapsulant. Vertical conductive interconnects may be formed over the first build-up interconnect structure and around an embedded device mount site. An embedded device comprising through silicon vias (TSVs) may be disposed over the embedded device mount site. A second encapsulant may be disposed over the build-up structure, and around at least five sides of the embedded device. A second build-up structure may be formed disposed over the planar surface and configured to be electrically coupled to the TSVs of the embedded device and the vertical conductive interconnects.
