    Abstract: A test structure to detect vertical leakage in a multi-layer flip chip pad stack or similar semiconductor device. The test structure is integrated into the semiconductor device when it is fabricated. A metal layer includes at least two portions that are electrically isolated from each other; one portion being disposed under a test pad, and another portion being disposed under a pad associated with a pad structure being tested. The metal layer in most cases is separated from a top metal layer directly underlying the pads by an inter-metal dielectric (IMD) layer. A metal layer portion underlying the pad to be tested forms a recess in which a conductive member is disposed without making electrical contact. The conductive line is electrically coupled to a test portion of the same or, alternately, of a different metal layer. The test structure may be implemented on multiple layers, with recesses portions underlying the same or different pads.

    Abstract: A test board includes a first chip mounting area, a first input area, a second input area, a first output area, and a second output area. The test board also includes a first conductive pattern, a second conductive pattern, a third conductive pattern, and a fourth conductive pattern. The first conductive pattern electrically connects a first pin of the first input area and a first pin of the first chip mounting area. The second conductive pattern electrically connects a first pin of the second input area and a second pin of the first chip mounting area. The third conductive pattern electrically connects a first pin of the first output area and a third pin of the first chip mounting area. The fourth conductive pattern electrically connects a first pin of the second output area and a fourth pin of the first chip mounting area.
