Abstract:
A Critical Dimensions Scanning Electron Microscope (CD-SEM) is described that comprises a unit for performing CD-SEM measurements of a semiconductor wafer, a BSE imaging unit for obtaining a Grey Level image (GL) of the wafer, and a unit for GL analysis and for processing the GL analysis results with reference to results of the CD-measurements.
Abstract:
A technique for visualizing elements in images by applying a color coding procedure to data which comprises an initial image and segmentation results based on N labels. The segmentation results comprise information on segmentation uncertainty. The color coding procedure constructs a resulting colored image based on the initial image and N pre-selected base colors, and in such a manner that colors in the resulting colored image are modified by using intensity of the initial image and the information on segmentation uncertainty.
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.
