Summary:Integrated circuits and processes for manufacturing integrated circuits are described that use printed wiring board substrates having a core layer that is part of the circuit of the printed wiring board. In a number of embodiments, the core layer is constructed from a carbon composite. In several embodiments, techniques are described for increasing the integrity of core layers in designs calling for high density clearance hole drilling. One embodiment of the invention includes a core layer that includes electrically conductive material and at least one build-up wiring portion formed on an outer surface of the core layer. In addition, the build-up portion comprises at least one micro wiring layer including a circuit that is electrically connected to the electrically conductive material in the core layer via a plated through hole.
