The present disclosure relates to a semiconductor device package and a method for manufacturing the semiconductor device package. The semiconductor device package includes a substrate, a grounding element, a component, a package body and a conductive layer. The grounding element is disposed in the substrate and includes a connection surface exposed at a second portion of a lateral surface of the substrate. The component is disposed on a top surface of the substrate. The package body covers the component and the top surface of the substrate. A lateral surface of the package body is aligned with the lateral surface of the substrate. The conductive layer covers a top surface and the lateral surface of the package body, and further covers the second portion of the lateral surface of the substrate. A first portion of the lateral surface of the substrate is exposed from the conductive layer.
