Abstract:
A pattern measuring method and a pattern measuring apparatus that efficiently prevent a measurement error inherent to a device that performs beam scanning in a specific direction such as a scanning electron microscope are provided. The invention is directed to a pattern measuring method and a pattern measuring apparatus in which a first curve with respect to an edge of one side and a second curve with respect to an edge of the other side are obtained by calculating a first power spectral density with respect to the edge of one side of a pattern and a second power spectral density with respect to the edge of the other side of the pattern based upon a signal that is obtained when a charged particle beam is scanned in a direction intersecting the edge of the pattern; a difference value between the first curve and the second curve is calculated; and one of the first curve and the second curve is corrected by using the difference value.

Claim (Index 5):
A pattern measuring apparatus for measuring a pattern formed on a sample by using a signal that is obtained from a scanning region by scanning a beam on the sample, comprising:\n an arithmetic processing device in which the signal is acquired; a first curve with respect to an edge of one side of the pattern and a second curve with respect to an edge of the other side of the pattern are obtained by calculating a first power spectral density with respect to the edge of one side of the pattern and a second power spectral density with respect to the edge of the other side of the pattern based upon a signal that is obtained by scanning the beam in a direction intersecting the edge of the pattern; a difference value between the first curve and the second curve is calculated; and one of the first curve and the second curve is corrected by using the difference value.
