    Abstract: The present disclosure relates to thin-form-factor semiconductor packages with integrated electromagnetic interference (“EMI”) shields and methods for forming the same. The packages described herein may be utilized to form high-density semiconductor devices. In certain embodiments, a silicon substrate is laser ablated to include one or more cavities and a plurality of vias surrounding the cavities. One or more semiconductor dies may be placed within the cavities and thereafter embedded in the substrate upon formation of an insulating layer thereon. A plurality of conductive interconnections are formed within the vias and may have contact points redistributed to desired surfaces of the die-embedded substrate assembly. Thereafter, an EMI shield is plated onto a surface of the die-embedded substrate assembly and connected to ground by at least one of the one or more conductive interconnections. The die-embedded substrate assembly may then be singulated and/or integrated with another semiconductor device.

    Abstract: The present disclosure relates to semiconductor core assemblies and methods of forming the same. The semiconductor core assemblies described herein may be utilized to form semiconductor package assemblies, PCB assemblies, PCB spacer assemblies, chip carrier assemblies, intermediate carrier assemblies (e.g., for graphics cards), and the like. In one embodiment, a silicon substrate core is structured by direct laser patterning. One or more conductive interconnections are formed in the substrate core and one or more redistribution layers are formed on surfaces thereof. The silicon substrate core may thereafter be utilized as a core structure for a semiconductor package, PCB, PCB spacer, chip carrier, intermediate carrier, or the like.
