Abstract

A microwave system includes a molding compound layer having opposing first and second surfaces, an integrated circuit device at least partially surrounded by said molding compound layer to define a fan-out area located laterally outside the integrated circuit device's outline, a plurality of through-mold vias within said fan-out area extending through said molding compound layer between said first and second surfaces, a re-distribution layer stack extending parallel to said second surface and comprising conducting signal paths, and a substrate comprising a first surface extending parallel to the molding compound layer. The re-distribution layer stack is positioned on top of an array of solder balls carried by the substrate. The system also includes two coupling slots arranged on different levels to resonantly couple with each other, and at least one hollow waveguide with an open (coupling) aperture at one end in direct proximity of one of said two coupling slots.
