INSPECTION APPARATUS AND METHOD BY ELECTRON BEAM, AND DEVICE MANUFACTURING METHOD USING THE INSPECTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve an inspection speed detecting a failure of a sample of a wafer, etc. SOLUTION: An inspection apparatus by an electron beam is one of a mapping projection type and comprises: a primary electron optical system for forming the electron beam emitted from en electron gun into a rectangle and irradiating onto a face of a sample to be inspected; a secondary electron optical system for converging secondary electrons emitted from the sample; a detection device for converting the converged secondary electrons into an optical image through a fluorescent plate to image them to a line sensor; and a control device for controlling charge moving time to transfer the line image which is imaged in a pixel string provided with the line sensor, cooperatively with the moving speed of a stage to move the sample.
