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 composite panel having front and back faces, the panel comprising facing reinforcement, backing reinforcement and matrix material binding to the facing and backing reinforcements, the facing and backing reinforcements each independently comprising (i) one or more reinforcing sheets and/or (ii) one or more generally planar arrays of longitudinally arranged, spaced apart, reinforcing rods which are interconnected by means for resisting increase of the spacing distance between adjacent rods, at least one rod array (ii) being present in the facing and/or backing reinforcement wherein the means for resisting increase of the spacing distance between adjacent rods is transverse filamentary interlacing of rods in the array, the facing reinforcement being located on or embedded in matrix material adjacent to the front face of the panel, the backing reinforcement being located in a plane or planes substantially parallel to the plane or planes of the facing reinforcement, and being substantially coextensive therewith,

Abstract: A blast-and projectile-impact resistant structure comprising a freight container which is at least partially clad internally and/or externally with a barrier structure comprising a single panel or a plurality of panels of matrix material incorporating reinforcement elements, the structure having means for human entry into and exit from the interior of the container located in a wall and, if necessary also in the barrier structure.
