Abstract
Microelectronic packages, modules, systems, and other assemblies containing enhanced electromagnetic (EM) shield structures are provided, as are methods for fabricating electromagnetically-shielded microelectronic assemblies. In an embodiment, the electromagnetically-shielded microelectronic assembly includes first and second signal paths, which carry different electrical signals during operation of the microelectronic assembly. An EM shield structure is positioned between the first and second signal paths. The EM shield structure includes, in turn, a magnetic shield portion adjacent (e.g., in contact with and/or directly or indirectly bonded to) an electrical shield portion. The magnetic shield portion has a first magnetic permeability and a first electrical conductivity, while the electrical shield portion has a second magnetic permeability less than the first magnetic permeability and having a second electrical conductivity greater than the first electrical conductivity.
