  • Method and scanning electron microscope for measuring width of material on sample
    Patent number: 7385196
    Abstract: A width-measurement method of reducing or eliminating an error in measurement of a width of an object on a sample resulting from the dimension of the beam diameter, wherein a width-measured value of the object to be width-measured which has been obtained on the basis of a secondary signal obtained from secondary particles emitted from the sample having thereon the object to be width-measured is corrected with a value with respect to a dimension value of a beam diameter.
    Type: Grant
    Filed: August 5, 2004
    Date of Patent: June 10, 2008
    Assignee: Hitachi High-Technologies Corporation
    Inventors: Goroku Shimoma, Tadashi Otaka, Mitsugu Sato, Hideo Todokoro, Shunichi Watanabe, Tadanori Takahashi, Masahiro Kawawa, Masanori Gunji, Terumichi Nishino
