처리량이 증가된 반도체 웨이퍼의 체적 검사 시스템 및 방법이 제공된다. 시스템 및 방법은 검사 체적에서 적절한 단면 표면의 감소된 수 또는 영역을 밀링 및 이미징하고 단면 표면 이미지로부터 3D 물체의 검사 파라미터를 결정하도록 구성된다. 방법 및 디바이스는 반도체 웨이퍼 내의 집적 회로의 정량적 계측, 결함 검출, 프로세스 모니터링, 결함 검토, 및 검사에 이용될 수 있다. A system and a method for volume inspection of semiconductor wafers are configured for milling and imaging of reduced number or areas of appropriate cross-sections surfaces in an inspection volume and determining inspection parameters of the 3D objects from the cross-section surface images. The system and method can be utilized for quantitative metrology, defect detection, process monitoring, defect review, and inspection of integrated circuits within semiconductor wafers.
