1. A semiconductor package comprising:

  • a semiconductor die;

    a plurality of leads extending at least partially about the semiconductor die which is electrically connected to at least some of the leads;

    a package body covering at least portions of the semiconductor die and the leads, the package body having a top surface, a bottom surface, a shoulder which is disposed in opposed relation to the bottom surface and recessed relative to the top surface, a first side surface which extends between the top surface and the shoulder, and a second side surface which extends between the shoulder and the bottom surface, the package body being formed such that one or more, but not all, of the leads include a portion which is exposed in the shoulder, and each of the leads includes a portion which is exposed in the bottom surface; and

    a conformal shield which is disposed on at least a portion of the package body and is electrically connected to any portions of the leads which are exposed in the shoulder.
