Abstract: A shield for an integrated circuit comprising an upper wall and a side wall assembly. The upper wall includes a top surface, a bottom surface and a perimeter. The side wall assembly depends from the perimeter of the upper wall. The side wall assembly has a proximal end, a distal end, an inner surface and an outer surface. The distal end defines a lower edge. At least a portion of the side wall assembly includes a plurality of surface variations along a length thereof, to, in turn, define a lower edge of the side wall assembly having a non-linear configuration. Such a non-linear configuration increases the rigidity of the shield.
