Abstract
A mechanism is provided to reduce a distance of a waveguide antenna from transmit and receive circuitry in an integrated circuit device die. This distance reduction is performed by providing vertical access to radio frequency connections on a top surface of the IC device die. A cavity in the encapsulant of the package can be formed to provide access to the connections and plated to perform a shielding function. A continuous connection from the RF pads is used as a vertical interconnect. The region around the vertical interconnect can be filled with encapsulant potting material and back grinded to form a surface of the semiconductor device package. A waveguide antenna feed can be plated or printed on the vertical interconnect on the surface of the package.
