Abstract:
1. A semiconductor device, comprising: a semiconductor substrate having a front surface and a back surface; a plurality of elements formed on the substrate; a plurality of interconnect metal layers formed over the front surface of the substrate, including a topmost interconnect metal layer having a first topmost surface measured a first distance from the front surface of the substrate and a first bottommost surface measured a third distance from the front surface of the substrate; an inter-metal dielectric for insulating each of the plurality of interconnect metal layers disposed therein; and a bonding pad disposed within the inter-metal dielectric, the bonding pad in contact with one of the plurality of interconnect metal layers other than the topmost interconnect metal layer, the bonding pad having a second topmost surface measured a second distance from the front surface of the substrate and a second bottommost surface measured a fourth distance from the front surface of the substrate; wherein:
