Abstract: Coil structures and methods of forming are provided. The coil structure includes a substrate. A plurality of coils is disposed over the substrate, each coil comprising a conductive element that forms a continuous spiral having a hexagonal shape in a plan view of the coil structure. The plurality of coils is arranged in a honeycomb pattern, and each conductive element is electrically connected to an external electrical circuit.

Abstract: In an embodiment, a structure includes: a first integrated circuit die including first die connectors; a first dielectric layer on the first die connectors; first conductive vias extending through the first dielectric layer, the first conductive vias connected to a first subset of the first die connectors; a second integrated circuit die bonded to a second subset of the first die connectors with first reflowable connectors; a first encapsulant surrounding the second integrated circuit die and the first conductive vias, the first encapsulant and the first integrated circuit die being laterally coterminous; second conductive vias adjacent the first integrated circuit die; a second encapsulant surrounding the second conductive vias, the first encapsulant, and the first integrated circuit die; and a first redistribution structure including first redistribution lines, the first redistribution lines connected to the first conductive vias and the second conductive vias.
