Zusammenfassung:A failure analysis unit is a wafer conveyance unit configured to convey a wafer while holding the wafer in a semiconductor failure analysis apparatus, the wafer conveyance unit including: a placement table configured to fix a wafer at a predetermined observation position; and a wafer chuck configured to convey the wafer while holding the wafer to the observation position. The wafer chuck includes a plurality of holding members (protruding portions) provided so as to face a side surface of the wafer, and holds the wafer by sandwiching a peripheral portion of the wafer W with the plurality of holding members.
