Patent ID: 8853692

Claim:
A test structure for measuring bond pad quality, comprising: a metal element defined over a dielectric layer; and a passivation layer disposed over the metal element and disposed over a portion of a bond pad metal, the bond pad metal on an uppermost metal layer of a bond pad, the bond pad configured to receive during packaging assembly a bonding component contacting the bond pad metal, the passivation layer having a plurality of openings that expose a top surface of the metal element, the openings including a first opening that provides a first probe point, a second opening that provides a second probe point, a third opening that provides a third probe point, and a fourth opening between the second opening and the third opening, each of the first opening, the second opening and the third opening configured to be probed with a probe contacting the top surface of the metal element during on-wafer testing at sort, with the first probe point, the second probe point and the third probe point defining a voltage divider in the metal element.
