Abstract:
Disclosed herein is a charged particle beam apparatus ( 10 ) includes: a sample chamber ( 11 ); a sample stage ( 31 ); an electron beam column ( 13 ) irradiating a sample S with an electron beam; and a focused ion beam column ( 14 ) irradiating the sample S with a focused ion beam. The apparatus ( 10 ) includes a displacement member ( 45 ) having: an open/close portion provided to be displaceable between an insertion position between a beam emitting end portion of the electron beam column ( 13 ) and the sample stage ( 31 ), and a withdrawal position away from the insertion position; and a contact portion provided at a contact position capable of contacting the sample S before the beam emitting end portion during operation of the sample stage ( 31 ). The apparatus ( 10 ) includes: a driving unit  42  displacing the displacement member ( 45 ); and a conduction sensor ( 24 ) detecting whether the sample is in contact with the contact portion.

Claim (Index 1):
A charged particle beam apparatus comprising:\n a sample stage on which a sample is placed; a sample chamber receiving the sample stage therein; a charged particle beam column irradiating the sample with a charged particle beam; a displacement member including an open/close portion provided to be displaceable between an insertion position, which is between a beam emitting end portion of the charged particle beam column and the sample stage, and a withdrawal position which is away from the insertion position, and a contact portion provided at a contact position capable of contacting the sample before the beam emitting end portion during operation of the sample stage; a driving means displacing the displacement member; and a detecting means detecting whether the sample is in contact with the contact portion.
