Abstract
Embodiments of the present disclosure relate to in-line detection of electrical fails on integrated circuits. One embodiment is an apparatus including a device region with integrated circuits and a test region for in-line failure detection of the integrated circuits using an in-line voltage contrast test, the apparatus comprising: a substrate including a first area for the device region and a second different area for the test region; metal layers formed over both areas; wherein the integrated circuits are formed from first sections of the layers; and wherein a second section of an upper metal layer of the layers is segmented into test segments, each test segment to exhibit a predefined response during the in-line voltage contrast test depending on whether the test segment is shorted, or not, to the substrate and/or the second section of a gate layer of the layer. Other embodiments may be disclosed and/or claimed.
