Abstract:
1. An inspection method using a charged particle beam, the method comprising: irradiating a charged particle beam onto an object to be inspected; detecting a signal obtained from the object to be inspected; and forming an image from the detected signal, wherein an identical charged particle beam inspection apparatus carries out a plurality of types of inspections including a first, a second, and a third inspection which are a pattern defect inspection, a foreign material inspection, and an inspection for a defect in a multilayer, respectively, and in which charged particle beams having beam energies E wherein the relation between the beam energies E wherein the first inspection, the second inspection and the third inspections are performed sequentially in time with the first inspection being performed first, then the second inspection and then the third inspection.
