摘要: There is a machining method which shortens a cross-section forming time by an ion beam, a machining method which shortens a machining time for separating a micro sample from a wafer, and an ion beam machining system. The ion beam machining system has a vacuum container containing a duoplasmatron, non-axially symmetric ion beam lens and stencil mask, wherein a micro sample is removed from a sample by an argon ion beam having a steep beam profile in a direction perpendicular to the cross-section. The cross-section observations for wafer inspection/defect analysis used in device manufacture can be obtained in a short time. Further, there is a inspection/analysis method which does not cause defects even if a sample is removed and a wafer is returned to the process.
