Abstract
The present invention provides a semiconductor evaluation device for fabricating a suitable reference pattern utilized in comparison tests. The semiconductor evaluation device and computer program extract a process window in a more accurate range based on a two-dimensional evaluation of the pattern. In order to achieve the above described objects, the present invention includes a semiconductor evaluation device that measures the dimensions of the pattern formed over the sample based on a signal obtained by way of a charged particle beam device, selects a pattern whose dimensional measurement results satisfy specified conditions or exposure conditions when the pattern is formed, and forms synthesized contour data, by synthesizing contour data obtained from images of an identically shaped pattern in design data, and also a pattern formed under the selected exposure conditions or a pattern having a positional relation that is already known relative to the selected pattern.
