Abstract:
A fabrication method of a sample to be analyzed, wherein a sample for analyzing a defect that has occurred in a semiconductor device that includes a semiconductor substrate and an element formation portion formed in this semiconductor substrate is fabricated, comprising the steps of:removing said semiconductor substrate so as to expose a surface, the element formation portion, said surface faces the substrate and contacts said semiconductor substrate; forming a protective film on said exposed surface facing the substrate; extracting a sample body from said exposed surface, which faces the substrate, so that a cross section of said element formation portion is exposed, wherein said extracted sample body includes a defect and said protective film covers said defect; and setting said extracted sample body onto a sample supporting portion by securing a surface of said sample body, on a side opposite to said exposed surface facing the substrate, to said sample supporting portion.
