    摘要: A method and apparatus, and variations of each, for inspecting a wafer defining at least one die thereon is disclosed. The present invention first obtains the electronic image equivalent of two die, and then determines the x and y offset between those electronic images. Prior to inspection for defects, those two electronic images are aligned by adjusting the x and y positions of one electronic image of one die with respect to the electronic image of the other die. Once that is accomplished, the those electronic images are compared to detect any defects that may exist on one of the die.

    摘要: Methods and apparatus are providing for characterizing thin films in an integrated circuit device. A target including multiple layers is scanned using an x-ray emission inducer. X-ray emissions characteristic of materials in the target are measured. In one example, multiple beam energies are used to conduct the scan. In another example, continuously varying beam energies are used. Information such as K-ratios or the intensity of the x-ray emissions is provided to determine the thickness and/or composition of layers in the scan target.
