发明名称 FOREIGN MATTER OR ABNORMAL UNSMOOTHNESS INSPECTION APPARATUS AND FOREIGN MATTER OR ABNORMAL UNSMOOTHNESS INSPECTION METHOD
摘要 A foreign matter or abnormal unsmoothness inspection apparatus is constituted by a detecting member for detecting a foreign matter or abnormal unsmoothness by measuring smoothness of a surface of a substrate-like measuring object, a marking device for providing an dent on the surface of the measuring object with a predetermined horizontal distance from the foreign matter or abnormal unsmoothness, and a mass spectrum measuring device for measuring a mass spectrum of secondary ion emitted from a position with a predetermined distance from the dent by detecting the dent through impact and scanning of the surface of the measuring object with a primary ion beam.
