Abstract: Embodiments include package substrates and a method of forming the package substrates. A package substrate includes a dielectric having a cavity that has a footprint, a resistor embedded in the cavity of the dielectric, and a plurality of traces on the resistor, where a plurality of surfaces of the resistor are activated surfaces. The resistor may also have a plurality of sidewalls which may be activated sidewalls and tapered. The dielectric may include metallization particles/ions. The resistor may include resistive materials, such as nickel-phosphorus (NiP), aluminum-nitride (AlN), and/or titanium-nitride (TiN). The package substrate may further include a first resistor embedded adjacently to the resistor. The first resistor may have a first footprint of a first cavity that is different than the footprint of the cavity of the resistor. The resistor may have a resistance value that is thus different than a first resistance value of the first resistor.

Abstract: A microelectronic assembly is disclosed, comprising: a substrate having a core made of glass; and a first integrated circuit (IC) die and a second IC die coupled to a first side of the substrate. The core comprises a cavity, a third IC die is located within the cavity, and the core further comprises one or more conductive through-glass via (TGV) that facilitates electrical coupling between the first side of the substrate and an opposing second side of the substrate. In some embodiments, the cavity is a blind cavity; in other embodiments, the cavity is a through-hole. In some embodiments, the third IC die merely provides lateral coupling between the first IC die and the second IC die; in other embodiments, the third IC die also provides electrical coupling between the first side and the second side of the substrate with through-silicon vias.

Abstract: A semiconductor device substrate includes a front section and back section that are laminated cores disposed on a front- and back surfaces of a first core. The first core has a cylindrical plated through hole that has been metal plated and filled with air-core material. The front- and back sections have laser-drilled tapered vias that are filled with conductive material and that are coupled to the plated through hole. The back section includes an integral inductor coil that communicates to the front section. The first core and the laminated-cores form a hybrid-core semiconductor device substrate with an integral inductor coil.

Abstract: Conductive routes for an electronic substrate may be fabricated by forming an opening in a material, using existing laser drilling or lithography tools and materials, followed by selectively plating a metal on the sidewalls of the opening. The processes of the present description may result in significantly higher patterning resolution or feature scaling (up to 2× improvement in patterning density/resolution). In addition to improved patterning resolution, the embodiments of the present description may also result in higher aspect ratios of the conductive routes, which can result in improved signaling, reduced latency, and improved yield.
