Abstract

See full text

Provided are a semiconductor inspection device and a semiconductor inspection method such that in a specimen image in a single field of view obtained by an electron microscope, it is possible to suppress variations in the edge position measurement error attributable to the materials and structures of the lower layers of measured patterns by a first method, wherein the area in the field of view obtained by electron beam scanning is divided into a plurality of regions on the basis of information regarding the structures and materials of the object to be observed and the electron beam scanning conditions are changed for individual regions (805, 806), a second method, wherein, the image processing conditions are changed for individual regions resulting from division of the obtained images, or a third method, wherein the edge detection conditions are changed for individual regions resulting from the division within the edge inspection regions of the obtained images.
