Abstract:
The purpose of the present invention is to provide a defect inspection device with which it is possible to detect a latent flaw with a high precision or at a high speed. In order to fulfill this purpose, this defect inspection device is provided with: a sample support member that supports a sample irradiated by an electron beam emitted from an electron source; a negative voltage applying power source for forming a retarding electric field in relation to the electron beam that irradiates the sample supported by the sample support member; an imaging element at which an image of electrons reflected without reaching the sample is formed via the retarding electric field; an ultraviolet light source that emits an ultraviolet light toward the sample; and a computation processing device that processes an image generated on the basis of a signal obtained by the imaging element. The computation processing device determines the type of defect in the sample on the basis of a plurality of image signals obtained when the ultraviolet light was emitted under at least two emitting conditions.

Claim (Index 8):
The defect inspection device according to  claim 1 ,\n wherein the processor determines a type of the defect on the basis of combination of characteristics extracted from the plurality of image signals.
