ABSTRACT:
Disclosed is an integrated circuit chip having an improved ESD protection structure. The integrated circuit chip includes a core logic region having a plurality of transistor devices that are interconnected to form a specific integrated circuit device. A plurality of input/output cells are defined along a periphery of the integrated circuit chip. An ESD bus die edge seal that defines a single ring around the periphery of the integrated circuit chip is provided. The ESD bus die edge seal is positioned outside of the plurality of input/output cells closest to a physical outer edge of the integrated circuit chip. Further, a plurality of (Vss) supply cells are contained in selected ones of the plurality of input/output cells. And, a plurality of ESD cross-coupled diodes are connected between the plurality of (Vss) supply cells and the ESD bus die edge seal. Advantageously, this combined ESD bus and die edge seal provides a more compact structure that also has more uniform charged contaminant collection characteristics.
