Abstract

A chip package includes a circuit board having a first surface with an inner die-attach region, an outer signal trace region and an intermediate utility region. Within the utility region are a number of traces for providing fixed electrical potentials to an integrated circuit die mounted within the die-attach region. In the preferred embodiment, the utility region includes a ring-like ground trace, a V.sub.DD trace and a segmented outer trace, with the segments of the segmented trace being connected to at least two fixed voltages for operating the integrated circuit die. Bond wires or leads of a leadframe include inner wire/lead ends connected to input/output pads of the die and include outer wire/lead ends connected to either a trace or trace segment in the utility region or a signal trace located in the outer signal trace region. The resulting chip package may be of the ball grid array type.
