Patent ID: 7456503

Claim:
An arrangement, comprising: an integrated circuit die having an active surface and a back surface, the back surface being substantially opposite the active surface, the die including a plurality of bond pads, the plurality of bond pads including at least a set of signal bond pads configured for carrying electrical signals and a set of power bond pads configured for coupling to power or ground lines, the die further including one or more metallic layers deposited substantially uniformly over portions of the active surface of the die and arranged so as to redistribute at least two of the power bond pads to form at least one extended I/O pad that is electrically connected with each of the associated at least two power bond pads together, each extended I/O pad extending to at least one peripheral side edge of the die; a substrate having a plurality of contact pads formed thereon and arranged to correspond to associated bond pads on the active surface of the die, wherein at least each contact pad that corresponds to an extended I/O pad has a footprint that is substantially larger than a footprint of the associated extended I/O pad such that the peripheral side edge of the contact pad extends beyond the associated peripheral side edge of the extended I/O pad and die; and a plurality of solder joint connections that mechanically and electrically connect the bond pads on the active surface of the die with associated contact pads on the substrate, wherein each solder joint connection corresponding to an extended I/O pad forms a fillet of solder between the extended I/O pad and the associated contact pad on the substrate such that the fillet extends from the peripheral side edge of the extended I/O pad outward towards the peripheral side edge of the associated contact pad on the substrate.
