  • Patent number: 10073135
    Abstract: Among other things, one or more techniques or systems for evaluating a tiered semiconductor structure, such as a stacked CMOS structure, for misalignment are provided. In an embodiment, a connectivity test is performed on vias between a first layer and a second layer to determine a via diameter and a via offset that are used to evaluate misalignment. In an embodiment, a connectivity test for vias within a first layer is performed to determine an alignment rotation based upon which vias are connected through a conductive arc within a second layer or which vias are connected to a conductive pattern out of a set of conductive patterns. In this way, the via diameter, the via offset, or the alignment rotation are used to evaluate the tiered semiconductor structure, such as during a stacked CMOS process, for misalignment.
