    Abstract: Routing substrates, methods of manufacture, and electronic assemblies including routing substrates are described. In an embodiment, a routing substrate includes a plurality of metal routing layers, a plurality of dielectric layers including a top dielectric layer forming a topmost surface, and a cavity formed in the topmost surface. The cavity may include a bottom cavity surface, a first plurality of first surface mount (SMT) metal bumps embedded within the top dielectric layer and protruding from the topmost surface of the top dielectric layer, and a second plurality of second SMT metal bumps embedded within an intermediate dielectric layer of the plurality of dielectric layers and protruding from the bottom cavity surface.

    Abstract: An asymmetric stackup structure for an SoC package substrate is disclosed. The package substrate may include a substrate with one or more insulating material layers. A first recess may be formed in an upper surface of the substrate. The recess may be formed down to a conductive layer in the substrate. An integrated passive device may be positioned in the recess. A plurality of build-up layers may be formed on top of the substrate. At least one via path may be formed through the build-up layers and the substrate to connect contacts on the lower surface of the substrate to contacts on the upper surface of the build-up layers.
