Zusammenfassung:	The disclosed subject matter relates to a structure and method to improve bond pad reliability of semiconductor devices. According to an aspect of the present disclosure, a bond pad structure is provided that includes a dielectric layer and at least one bond pad in the dielectric layer, wherein the bond pad has a top surface. A passivation layer has an opening over the bond pad, wherein the opening has sidewalls. A low-k barrier layer is covering the sidewalls of the opening and the top surface of the bond pad. Protective structures are formed over the sidewalls of the opening.
