Drift correction for scanning-electron microscopy
Scanning electron micrographs at high magnification (100,000x and up) are distorted by motion of the sample during image acquisition, a phenomenon called drift. We propose a method for correcting drift distortion in images obtained on scanning electron and other scanned-beam microscopes by …

Analysis and reduction of variability in scanning electron microscopy measurements of critical dimensions
This thesis describes work done during a Leaders for Manufacturing internship at Intel. At the broadest level, this work relates to the importance of controlling and monitoring measurement processes just as one controls the "fundamental" processes being measured. Without such control there can be …
