Abstract:
1. An apparatus for arranging a recipe for imaging with a scanning electron microscope, the apparatus comprising: a database which receives and stores layout information on a circuit pattern formed on a semiconductor wafer; an input means which inputs arranging conditions of an imaging-recipe; and an imaging-recipe arranging means which arranges the imaging-recipe determining an imaging sequence for acquiring SEM images in order to measure dimensions of the circuit pattern, and a portion to be imaged and imaging conditions to be used in the imaging sequence, by using the layout information on the semiconductor wafer circuit pattern stored into the database; wherein, the imaging-recipe arranging means sets a first region including a second region for acquiring a SEM image intended to measure the circuit pattern as the portion to be imaged in the imaging sequence, and a third region for imaging to evaluate a shift in position between the SEM image of the pattern in the first region and an image template corresponding to the SEM image of the pattern at a portion different from the second region in the first region, on the basis of the arranging conditions of the imaging-recipe inputted by the input means.
