Claim 16:
17. A semiconductor device package comprising:
a semiconductor die;
a redistribution layer (RDL) structure electrically connected on a first major surface thereof to the semiconductor die, the RDL structure comprising:
one or more levels of conductive traces, at least some of the one or more levels of conductive traces extending laterally beyond a periphery of the semiconductor die;
contacts electrically connected to the one or more levels of conductive traces defining a pattern for terminal pads on a second major surface of the RDL structure;
external conductive elements protruding from the terminal pads; and
a reinforcement structure extending between the first major surface of the RDL structure and the second major surface of the RDL structure, the reinforcement structure including mulitples levels of mutually parallel beams, the mutually parallel beams of adjacent levels defining a square-wave pattern extending parallel to and inward of each peripheral edge of the RDL structure, the reinforcement structure comprising a conductive material, and the reinforcement structure electrically isolated from the one or more levels of conductive traces and the contacts.
