    Abstract: Routing substrates, methods of manufacture, and electronic assemblies including routing substrates are described. In an embodiment, a routing substrate includes a metal routing layer including a first set of first wiring traces and a second set of second wiring traces, where first top surfaces of the first wiring traces are characterized by a lower RMS surface roughness (Rq) than the second top surfaces of the second wiring traces.

    Abstract: A system in package (SiP) is disclosed that uses an EMI shield to inhibit EMI or other electrical interference on the components within the SiP. A metal shield may be formed over the SiP. The metal shield may be electrically coupled to a ground layer in a printed circuit board (PCB) to form the EMI shield around the SiP. The substrate of the SiP may include at least some metallization along vertical walls in the end portions of the substrate. The metallization may provide a large contact area for coupling the metal shield to a ground ring coupled to the ground layer in the PCB. The metallization along the vertical walls in the end portions of the substrate may be formed as through-metal vias in a common substrate before singulation to form the SiP.

    Abstract: Packages including substrate-less integrated components and methods of fabrication are described are described. In an embodiment, a packaging method includes attaching a ground structure to a carrier and a plurality of components face down to the carrier and laterally adjacent to the ground structure. The plurality of components are encapsulated within a molding compound, and the carrier is removed exposing a plurality of component terminals and a plurality of ground structure terminals. A plurality of packages are singulated.
