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 11):
The sample observation method according to  claim 10 , further comprising:\n steps which input information of said sample, determine whether an optimization procedure for a scanning strategy of said electron beam is necessary, provide candidate scanning method(s) to said sample upon determining the optimization procedure is necessary, acquire images of said sample with the candidate scanning method(s), wherein at least one of the following information is derived from said images taken by said scanning electron microscope: (1) brightness of the image(s), (2) contrast of edge(s) of features of said sample, (3) uniformity of the brightness of said images, (4) uniformity of said contrast of said edge(s) in said image(s), and a signal-to-noise ratio of said image(s).
