Abstract: The present invention relates to adjustment of a mask position by driving an R-axis of an electron microscope in order to adjust the mask position with high accuracy while performing observation by the electron microscope without providing a heat generation source inside the electron microscope. The R-axis originally exists in a sample chamber of the electron microscope, which enables control with high accuracy. The R-axis driving of a sample stage can be substituted by raster rotation, therefore, the mask position can be adjusted with high accuracy while performing observation by the electron microscope according to the present invention.
