Patent ID: 8498470

Claim:
A method for evaluating one or more dice, the method comprising: obtaining, using an imaging device, an image of an area of the one or more dice, the area of the dice comprising multiple arrays of repetitive structural elements that are at least partially surrounded by one or more groups of non-repetitive regions, wherein for each subject group of non-repetitive regions, non-repetitive regions of the subject group are arranged in a repetitive manner; and comparing image information of a first sub-area of the area to image information of a second sub-area of the area that is proximate to the first sub-area, the first sub-area comprising a first array of the multiple arrays of repetitive structural elements and a first non-repetitive region and the second sub-area comprising a second array of the multiple arrays of repetitive structural elements and a second non-repetitive region; and responsive to the comparing, providing an evaluation result indicative of whether or not defects are present in the sub-areas that were compared.
