Abstract: A semiconductor device assembly is provided. The assembly includes a redistribution layer (RDL) including a plurality of external contacts on a first side and a plurality of internal contacts on a second side opposite the first side. The assembly further includes a first die at least partially embedded in the RDL and having an active surface between the first side and the second side of the RDL. The assembly further includes one or more second dies disposed over the controller die and the RDL, wherein the one or more second dies electrically coupled to the internal contacts. The assembly further includes an encapsulant at least partially encapsulating the one or more second dies.

Abstract: Semiconductor device packages may include a first semiconductor device over a substrate and a second semiconductor device over the first semiconductor device. An active surface of the second semiconductor device may face away from the substrate. Conductors may extend from bond pads of the second semiconductor device, along surfaces of the second semiconductor device, first semiconductor device, and substrate to pads of routing members of the substrate. The conductors may be in contact with the bond pads and the routing members and a dielectric material interposed between the conductors and the first semiconductor device and between the conductors and the second semiconductor device. An encapsulant distinct from the dielectric material may cover the conductors, the first semiconductor device, the second semiconductor device, and an upper surface of the substrate. Methods of fabrication are also disclosed.
