Described herein are semiconductor device packages with EMI shielding and related methods. In one embodiment, a semiconductor device package includes a circuit substrate, an electronic device, an encapsulant, and a conductive layer. The substrate includes a carrying surface, an opposing bottom surface, and a pad. The device is disposed adjacent to the carrying surface and is electrically connected to the substrate. The encapsulant is disposed adjacent to the carrying surface, encapsulates the device, and includes a center portion and a surrounding peripheral portion that is less thick than the center portion. An opening exposing the pad is formed in the peripheral portion. The conductive layer conformally covers the encapsulant and traverses the opening to connect to the pad.
