Device and method of manufacture for an integrated circuit having a BIST circuit and bond pads incorporated therein

Abstract

The present invention provides, in one embodiment, an integrated circuit having a substrate and active devices formed on the surface of the substrate. Other embodiments of the integrated circuit provide for having at least either three or four metal layers. In a particular embodiment of the present invention, the integrated circuit comprises a bond pad formed over a portion of the active devices. The bond pad has a footprint. As used therein the word footprint means the area covered by the device to which the word refers. The integrated circuit further incudes a patterned metal layer having a metal layer footprint that is located between the bond pad and the substrate and a built-in self-test (BIST) circuit that has a BIST footprint, which is located between the substrate and the bond pad. In this particular embodiment, the bond pad footprint overlays at least a portion of the metal layer footprint and the BIST footprint. However, in a more advantageous embodiment, the bond pad footprint overlays a substantial portion of the metal layer footprint and the BIST footprint.
