An operator-free and fully automated semiconductor inspection system with
high throughput is realized. All conditions required for capturing and
inspection are generated from design information such as CAD data. In
order to perform actual inspection under the conditions, a semiconductor
inspection system is composed of a navigation system for generating all
the conditions required for capturing and inspection from the design
information and a scanning electron microscope system for actually
performing capturing and inspection. Moreover, in the case of performing
a matching process between designed data and a SEM image, deformed parts
are corrected by use of edge information in accordance with multiple
directions and smoothing thereof. Furthermore, a SEM image corresponding
to a detected position is re-registered as a template, and the matching
process is thereby performed.
