Abstract:
A scanning electron microscope of the present invention performs scanning by changing a scanning line density in accordance with a sample when an image of a scanned region is formed by scanning a two-dimensional region on the sample with an electron beam or is provided with a GUI having sample information input means which inputs information relating to the sample and display means which displays a recommended scanning condition according to the input and performs scanning with a scanning line density according to the sample by selecting the recommended scanning condition. As a result, in observation using a scanning electron microscope, a suitable scanning device which can improve contrast of a profile of a two-dimensional pattern and suppress shading by suppressing the influence of charging caused by primary charged particle radiation and by improving a detection rate of secondary electrons and a scanning method are provided.

Claim (Index 1):
A scanning electron microscope which forms an image of a scanned region by scanning a two-dimensional region on a sample with an electron beam, wherein:\n the scanning electron microscope suppresses a number of injected electrons injected on said sample by said electron beam per individual single line scanned in a direction of said scanning by determining a probe current and a scan speed of scanning said individual single lines by said electron beam such that a scanning line density, which is a charge amount injected per unit of length on the sample by scanning of said electron beam, for each individual single line scanned by the electron beam on said sample is a predetermined value or less based on one or more electric characteristics of said sample derived from said images, and said sample is scanned in individual single lines by the electron beam based on the determined probe current and scan speed.
