  • Publication number: 20240088059
    Abstract: An electronic device structure having a shielding structure includes a substrate with an electronic component electrically connected to the substrate. The shielding structure includes conductive spaced-apart pillar structures that have proximate ends connected to the substrate and distal ends spaced apart from the substrate, and that are laterally spaced apart from the first electronic component. In one embodiment, the conductive pillar structures are conductive wires attached at one end to the substrate with an opposing end extending away from the substrate so that the conductive wires are provided generally perpendicular to the substrate. A package body encapsulates the electronic component and the conductive spaced-apart pillar structures. In one embodiment, the shielding structure further includes a shielding layer disposed adjacent to the package body, which is electrically connected to the conductive spaced-apart pillar structures.
