Paper Abstract

In this paper, we apply image-processing techniques to the task of metrology on complex shapes. We describe techniques for noise reduction, edge detection, and feature contour extraction on scanning electron microscope images. We present a novel capability for calculating the area of an arbitrary shape. We demonstrate imaged based metrology capabilities using examples encountered in photomask processing.
