    Abstract: A semiconductor device has a first interconnect structure formed over the carrier. A semiconductor die is disposed over the first interconnect structure after testing the first interconnect structure to be known good. The semiconductor die in a known good die. A vertical interconnect structure, such as a bump or stud bump, is formed over the first interconnect structure. A discrete semiconductor device is disposed over the first interconnect structure or the second interconnect structure. An encapsulant is deposited over the semiconductor die, first interconnect structure, and vertical interconnect structure. A portion of the encapsulant is removed to expose the vertical interconnect structure. A second interconnect structure is formed over the encapsulant and electrically connected to the vertical interconnect structure. The first interconnect structure or the second interconnect structure includes an insulating layer with an embedded glass cloth, glass cross, filler, or fiber.

    Abstract: A semiconductor device has a semiconductor package and an interposer disposed over the semiconductor package. The semiconductor package has a first semiconductor die and a modular interconnect unit disposed in a peripheral region around the first semiconductor die. A second semiconductor die is disposed over the interposer opposite the semiconductor package. An interconnect structure is formed between the interposer and the modular interconnect unit. The interconnect structure is a conductive pillar or stud bump. The modular interconnect unit has a core substrate and a plurality of vertical interconnects formed through the core substrate. A build-up interconnect structure is formed over the first semiconductor die and modular interconnect unit. The vertical interconnects of the modular interconnect unit are exposed by laser direct ablation. An underfill is deposited between the interposer and semiconductor package. A total thickness of the semiconductor package and build-up interconnect structure is less than 0.4 millimeters.

    Abstract: A semiconductor device has a first build-up interconnect structure formed over a substrate. The first build-up interconnect structure includes an insulating layer and conductive layer formed over the insulating layer. A vertical interconnect structure and semiconductor die are disposed over the first build-up interconnect structure. The semiconductor die, first build-up interconnect structure, and substrate are disposed over a carrier. An encapsulant is deposited over the semiconductor die, first build-up interconnect structure, and substrate. A second build-up interconnect structure is formed over the encapsulant. The second build-up interconnect structure electrically connects to the first build-up interconnect structure through the vertical interconnect structure. The substrate provides structural support and prevents warpage during formation of the first and second build-up interconnect structures. The substrate is removed after forming the second build-up interconnect structure. A portion of the insulating layer is removed exposing the conductive layer for electrical interconnect with subsequently stacked semiconductor devices.
