1. A semiconductor device package, comprising:

  • a substrate unit including an upper surface, a lower surface, and a lateral surface disposed adjacent to a periphery of the substrate unit;

    a grounding element disposed adjacent to the periphery of the substrate unit and extending upwardly from the upper surface of the substrate unit, the grounding element corresponding to a remnant of a conductive bump and including a lateral surface;

    a semiconductor device disposed adjacent to the upper surface of the substrate unit and electrically connected to the substrate unit;

    a package body disposed adjacent to the upper surface of the substrate unit and covering the semiconductor device and the grounding element, such that the lateral surface of the grounding element is electrically exposed, the package body including exterior surfaces that include a lateral surface, the lateral surface of the package body being substantially aligned with the lateral surface of the substrate unit; and

    an electromagnetic interference shield disposed adjacent to the exterior surfaces of the package body and electrically connected to the lateral surface of the grounding element,wherein the grounding element provides an electrical pathway to ground electromagnetic emissions incident upon the electromagnetic interference shield.
