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 4):
The apparatus of  claim 1 , further comprising:\n an electrical insulation member electrically insulating the displacement member from the sample chamber and the driving means, wherein the detecting means includes a power source applying a voltage to the displacement member from outside of the sample chamber and an electrical connection member electrically connecting the sample and the sample chamber and detects whether the sample is in contact with the contact portion based on whether there is conduction between the sample and the contact portion.
