Claim 7:
8. A packaged semiconductor device, comprising:
a printed circuit board substrate comprising at least a first waveguide aperture extending between first and second surfaces of the printed circuit board substrate;
a patterned conductive layer formed on the first surface of the printed circuit board substrate to define a first plurality of landing pads connected to one another by trace lines and disposed around peripheral edges of the first waveguide aperture;
a semiconductor device comprising a second plurality of landing pads formed on a first surface of the semiconductor device; and
a fully closed solder waveguide shielding wall attaching the patterned conductive layer to the second plurality of landing pads and disposed around peripheral edges of the first waveguide aperture to form a waveguide transition structure between the printed circuit board substrate and the semiconductor device.
