  • Patent number: 7663103
    Abstract: A line-width measurement adjusting method, which is used when first and second electron beam intensity distributions for measuring a line width are produced from intensity distribution images of secondary electrons obtained respectively by scanning a first irradiation distance with an electron beam at first magnification, and by scanning a second irradiation distance with an electron beam at second magnification, includes the step of adjusting the second electron beam intensity distribution of the electron beam at the second magnification such that the second electron beam intensity distribution is equal to the first electron beam intensity distribution of the electron beam at first magnification. The second electron beam intensity distribution may be adjusted by increasing or decreasing a second irradiation distance when producing the electron beam intensity distribution.

  • Patent number: 7590506
    Abstract: A pattern measurement apparatus includes a line profile creating unit for creating a line profile of a pattern formed on a sample by scanning with a charged particle beam, a derivative profile creating unit for creating a second derivative profile by differentiating twice the line profile, and an edge detecting unit for judging whether an edge in the pattern is a rising edge or a falling edge. Assuming that the two peak positions appearing in the vicinity of the edge position of the pattern obtained from the second derivative profile are defined as X1 and X2, X2 being larger than X1, the edge detecting unit judges that the edge is a rising edge when a signal amount in the peak position X1 is larger than a signal amount in the peak position X2.
