Claim:
A method for inspecting a diced object that comprises multiple dies, the method comprises: acquiring by an image acquisition unit multiple images of multiple portions of the diced object, starting from a first portion that comprises an alignment area and continuing through adjacent portions of the diced object; wherein the alignment area is used for aligning dies information with a coordinate system such as the global coordinate system; and wherein the acquiring of the multiple images comprises illuminating the diced wafer; assigning by a processor a die index to each die of the multiple dies of the diced object, starting from a die of the first portion and continuing through adjacent portions of the diced object; wherein the indexes are assigned to a continuous sequence of dies; associating by the processor between dies of the diced object and a die of a reference object in response to the assigned indexes and locations of the dies of the diced object; wherein the reference object is not diced; and comparing by a processor between a die of the diced object and another die while taking into account an association between the die of the diced object and a reference object die.
