SUBSTRATE INCLUDING STRUCTURES TO COUPLE A CAPACITOR TO A PACKAGED DEVICE AND METHOD OF MAKING SAME

摘要

Techniques and mechanisms to provide interconnect structures of a substrate such as a printed circuit board. In an embodiment, a first side of a substrate has disposed thereon a hardware interface contacts to couple the substrate to a packaged IC device. The contacts define a footprint area, where an overlap region of the substrate is defined by a projection of the footprint area from the first side to a second side of the substrate. The substrate forms a recess extending from one of the first side and the second side. In another embodiment, at least part of the recess is within the overlap region, and interconnect structures of the substrate facilitate connection between the packaged IC device and a capacitor disposed at least partially in the recess. Positioning of the capacitor within the overlap region enables improvements in substrate space efficiency, power delivery and/or signal noise.
