Abstract:
A method capable of verifying whether operation parameters, such as a focus parameter and an astigmatism correction parameter, of a scanning electron microscope are correctly adjusted. This method includes: determining a ratio of a length of an edge in a first direction to a length of the edge in a second direction perpendicular to the first direction, the edge being an edge of a pattern selected from design data; generating images of the pattern while changing an operation parameter of a scanning electron microscope; calculating an edge sharpness in the first direction of each of the images and calculating an edge sharpness in the second direction of each of the images; determining a ratio of a peak value of the edge sharpness in the first direction to a peak value of the edge sharpness in the second direction; and emitting an alarm if the ratio of the peak values does not coincide with the ratio of the lengths of the edge.

Claim (Index 1):
A method of verifying an operation parameter of a scanning electron microscope, comprising:\n determining a ratio of a length of an edge in a first direction to a length of the edge in a second direction perpendicular to the first direction, the edge being an edge of a pattern selected from design data; generating images of the pattern while changing the operation parameter of the scanning electron microscope; calculating an edge sharpness in the first direction of each of the images and calculating an edge sharpness in the second direction of each of the images; determining a ratio of a peak value of the edge sharpness in the first direction to a peak value of the edge sharpness in the second direction; and emitting an alarm if the ratio of the peak values does not coincide with the ratio of the lengths of the edge.
