Abstract:
A method for determining overlay between layers of a multilayer structure may include obtaining a given image representing the multilayer structure, obtaining expected images for layers of the multilayer structure, providing a combined expected image of the multilayer structure as a combination of the expected images of said layers, performing registration of the given image against the combined expected image, and providing segmentation of the given image, thereby producing a segmented image, and maps of the layers of said multilayered structure. The method may further include determining overlay between any two selected layers of the multilayer structure by processing the maps of the two selected layers together with the expected images of said two selected layers.

Claim (Index 33):
The non-transitory computer-readable medium according to  claim 30 , wherein to compute the overlay measurement between the two layers of the multilayer structure, the processor is to further:\n perform per-layer registration between a map of a specific layer of the two layers with the respective expected image of the specific layer; for each of the two layers, measure a shift of the specific layer by comparing the respective map of the specific layer with the respective expected image of the specific layer; and determine the overlay measurement between the two layers based at least partially on a difference between the measured shifts.
