A semiconductor chip having an on-chip ground plane comprising a low resistivity semiconductor region in a plurality of non-device regions of the chip and reach-through regions electrically connected to the low resistivity semiconductor region. One or more front-side contacts are used to electrically connect the reach-through regions and the low resistivity semiconductor region to a ground potential to electrically ground the on-chip ground plane.
