Claim One:
1. A pattern inspection method comprising: generating a charged particle beam to irradiate the charged particle beam to a sample having a surface on which a pattern to be inspected is formed; detecting at least one of a secondary charged particle, a reflection charged particle and a back scattering charged particle emitted from the sample due to the irradiation of the charged particle beam, and acquiring a first two-dimensional image showing a state of the surface of the sample; using a previously prepared reference image to detect a pattern similar to the reference image within the first two-dimensional image, and storing information on a position of the detected pattern as information on the position of the pattern to be inspected; moving a measurement position from the position of the detected pattern by a predetermined distance in a predetermined direction to focus the charged particle beam; moving the measurement position by the predetermined distance in a direction opposite to the predetermined direction to irradiate the charged particle beam, and acquiring a second two-dimensional image magnified higher than the first two-dimensional image to measure the detected pattern as a first measurement; and automatically moving the measurement position to an area other than an area on the sample to which the charged particle beam has been already irradiated to again carry out a measurement in the case of carrying out a remeasurement of the pattern to be inspected.
