摘要:
The present invention improves inspection efficiency in detailed inspections of defects performed based on inspection information from a defect inspection. Particles and defects are detected by a defect inspection device 1. If the cause of the particles and defects are to be determined by performing a detailed inspection with a details inspection device 3 using an SEM or the like, attributes are determined on the particles and defects detected by the defects inspection device 1 before the detailed inspection is performed. The attributes are determined with an attribute inspection device using an optical microscope or the like. Based on these attributes, the defects and particles are separated into those that require detailed inspection and those that do not require detailed inspection or that cannot be inspected in detail. A details inspection device 3 is used to inspect the particles and defects requiring detailed inspection.
