    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.

    Abstract: A substrate of a microelectronic assembly is provided, the substrate comprising conductive traces through an organic dielectric, and a coating comprising silicon and oxygen. The substrate is configured to couple with a component electrically and mechanically by at least one or more conductive via through the coating, the conductive via being electrically connected to the conductive traces, such that the coating is between the organic dielectric and the component when coupled. In some embodiments, the component includes another coating comprising silicon and oxygen, with conductive vias through the second coating. The conductive vias and the coating of the substrate are configured to bind with the conductive vias and the coating of the component respectively to form hybrid bonds.

    Abstract: Techniques and mechanisms for providing anisotropic etching of a metallization layer of a substrate. In an embodiment, the metallization layer includes grains of a conductor, wherein a first average grain size and a second average grain size correspond, respectively, to a first sub-layer and a second sub-layer of the metallization layer. The first sub-layer and the second sub-layer each span at least 5% of a thickness of the metallization layer. A difference between the first average grain size and the second average grain size is at least 10% of the first average grain size. In another embodiment, a first condition of metallization processing contributes to grains of the first sub-layer being relatively large, wherein an alternative condition of metallization processing contributes to grains of the second sub-layer being relatively small. A grain size gradient across a thickness of the metallization layer facilitates etching processes being anisotropic.
