Provided is a test structure for testing an unpackaged semiconductor wafer. The test structure includes a force-application component that is coupled to an interconnect structure of the semiconductor wafer. The force-application component is operable to exert a force to the semiconductor wafer. The test structure also includes first and second test portions that are coupled to the interconnect structure. The first and second test portions are operable to measure an electrical performance associated with a predetermined region of the interconnect structure. The first and second test portions are operable to measure the electrical performance while the force is exerted to the semiconductor wafer.
