In accordance with disclosed embodiments, there are provided methods, systems, and apparatuses for implementing an organic stiffener with an EMI shield for RF integration. For instance, in accordance with one embodiment, there is an apparatus having therein: a substrate layer having electrical traces and a ground plane therein; a functional semiconductor die electrically interfaced to the electrical traces of the substrate layer; a heat pipe thermally interfaced to a top surface of the functional semiconductor die; one or more interposers of an organic dielectric material electrically connected to the ground plane of the substrate layer and electrically connected to the heat pipe; in which the one or more interposers form the electromagnetic shield to electrically shield the functional semiconductor die; and further in which the one or more interposers form the organic stiffener are to mechanically retain the substrate layer in a planer form. Other related embodiments are disclosed.
