摘要：
We have developed a new system, "PF-3000", which realizes the pattern shape comparison between CAD layout data and CD-SEM images([1]). Comparison results are expressed as the difference of edge location and area in this system. Moreover, we investigated different methods of shape comparison. Fourier descriptor (FD)([2]) is one of the most useful method.
