Abstract
A pattern defect inspection method includes generating electron beam irradiation point track data on the basis of first data on an inspection target pattern, irradiating the electron beam to the inspection target pattern in accordance with the electron beam irradiation point track data, detecting secondary electrons generated from the inspection target pattern due to the irradiation of the electron beam, acquiring second data regarding a signal intensity of the secondary electrons from a signal of the detected secondary electrons, and detecting an abnormal point from the second data and outputting the abnormal point as a defect of the inspection target pattern. The electron beam irradiation point track data includes data on a track of irradiation points of an electron beam to the inspection target pattern and is intended to control over scanning with the electron beam, the electron beam irradiation point track data.
