Various embodiments include monitoring structures for integrated circuits (ICs) and related monitoring methods. In some cases, a monitoring structure includes: a set of serpentine-comb structures configured to connect with a back-end-of-line (BEOL) portion of the IC, each of the serpentine-comb structures including: a chain of interconnected laterally extending wires spanning a set of metal levels in the IC; and a set of vias connecting the chain of interconnected laterally extending wires across the set of metal levels, wherein the set of vias includes at least one via spanning between each successive level of the chain of interconnected laterally extending wires, wherein the chain of interconnected laterally extending wires and the set of vias are configured to detect a chip package interface (CPI) failure in the IC.

Chip package interaction (CPI) back-end-of-line (BEOL) monitoring structure and method

Bond pad structures and methods for fabricating bond pad structures. A bond pad and a plurality of fill lines are formed on the top surface of a dielectric layer. The fill lines are arranged on the top surface of the dielectric layer adjacent to the bond pad, and may be separated from the bond pad by a fill keep-out zone. One or more Under Bump Metallurgy (UBM) layers may be arranged on the bond pad and may extend outwardly to overlap with the fill lines.
