PATTERN DETERMINATION DEVICE AND COMPUTER PROGRAM

摘要

An object of the invention is to provide: a sample unevenness device that stably identifies unevenness formed on a sample, regardless of a pattern formation state or image acquisition conditions; and a computer program. As an aspect to achieve the above object, a device and computer program are proposed that obtain the area of a plurality of regions formed by a profile waveform of a given threshold or lower for a profile formed based on a detection signal obtained by scanning with a charged particle beam with respect to the sample; and determine either or both of that a site corresponding to a region with a relatively large area is a concave portion or that a space portion and a site corresponding to a space with a relatively small area is a convex portion or a line portion.
