Abstract:
An example integrated circuit die includes: lower level conductor layers, lower level insulator layers between the lower level conductor layers, lower level vias extending vertically through the lower level insulator layers, upper level conductor layers overlying the lower level conductor layers, upper level insulator layers between and surrounding the upper level conductor layers, upper level vias; at least two scribe seals arranged to form a vertical barrier extending vertically from the semiconductor substrate to a passivation layer at an upper surface of the integrated circuit die; and at least one opening extending vertically through one of the at least two scribe seals and extending through: the upper level conductor layers, the upper level via layers, the lower level conductor layers, and the lower level via layers.
