    Abstract: Techniques for self-assembly of regions in a dielectric layer with different electrical properties are described herein. In one example, a package includes a substrate, a layer of dielectric material over the substrate, the layer of dielectric material including a filler material. The package includes a plurality of conductive traces in the layer of dielectric material, and a filler-depleted radial region of the dielectric material around each of the plurality of conductive traces. The filler-depleted radial region has a lower volume-percentage of filler than other regions of the layer of dielectric material. In one example, the conductive traces, filler, or both include a coating to cause the filler and traces to have opposing surface chemistry.

    Abstract: Embodiments herein relate to a capacitor device or a manufacturing process flow for creating a capacitor that includes nanoislands within a package. The capacitor a first conductive plate having a first side and a second side opposite the first side and a second conductive plate having a first side and a second side opposite the first side where the first side of the first conductive plate faces the first side of the second conductive plate. A first plurality of nanoislands is distributed on the first side of the first conductive plate and a second plurality of nanoislands is distributed on the first side of the second conductive plate, where the first conductive plate, the second conductive plate, and the first and second pluralities of nanoislands form a capacitor. The nanoislands may be applied to the conductive plates using a sputtering technique.

    Abstract: Embodiments include package substrates and method of forming the package substrates. A package substrate includes a first encapsulation layer over a substrate, and a second encapsulation layer below the substrate. The package substrate also includes a first interconnect and a second interconnect vertically in the first encapsulation layer, the second encapsulation layer, and the substrate. The first interconnect includes a first plated-through-hole (PTH) core, a first via, and a second via, and the second interconnect includes a second PTH core, a third via, and a fourth via. The package substrate further includes a magnetic portion that vertically surrounds the first interconnect. The first PTH core has a top surface directly coupled to the first via, and a bottom surface directly coupled to the second via. The second PTH core has a top surface directly coupled to the third via, and a bottom surface directly coupled to the fourth via.
