Claim 8:
9. A redistribution layer (RDL) structure, comprising:
two or more levels of conductive traces between adjacent levels of low-k dielectric material; and
a reinforcement structure comprising a conductive material, the reinforcement structure electrically isolated from the two or more levels of conductive traces, the reinforcement structure extending between a first major surface and a second major surface of the RDL structure, the reinforcement structure comprising multiple levels of beams, the multiple levels of beams proximate to and inward of a periphery of the RDL structure, the multiple levels of beams comprising:
a first level including first beams parallel to one another;
a second level including second beams parallel to one another and perpendicular to the first beams; and
a third level, the second level between the first level and the third level, the third level including third beams extending parallel to and beneath the first beams, the first beams connected to the third beams by column elements.
