ABSTRACT:
A semiconductor device (10) includes a voltage distribution ring (20) attached to a plurality of leads (16). The ring is made up of an insulating layer (24), preferably polyimide, and a metal layer (22), preferably gold-plated copper foil. The ring may also include intervening adhesive layers (not illustrated). The ring surrounds a semiconductor die (12) and is electrically coupled to bond pads (14) of the die by wire bond (18). In various embodiment of the invention, the ring may be segmented to distribute two different voltages, such as power and ground; the ring may include slots to expose underlying portions of the leads; and the ring may be attached to either the top surface or bottom surface of the leads.
