Abstract:
Disclosed is a composite beam apparatus capable of suppressing the influence of charge build-up, or electric field or magnetic field leakage from an electron beam column when subjecting a sample to cross-section processing with a focused ion beam and then performing finishing processing with another beam. The Composite beam apparatus includes: an electron beam column irradiating an electron beam onto a sample; a focused ion beam column irradiating a focused ion beam onto the sample to form a cross section; a neutral particle beam column having an acceleration voltage set lower than that of the focused ion beam column, and irradiating a neutral particle beam onto the sample to perform finish processing of the cross section, wherein the electron beam column, the focused ion beam column, and the neutral particle beam column are arranged such that the beams of the columns cross each other at an irradiation point.

Claim (Index 5):
The composite beam apparatus of  claim 1 , wherein the electron beam column has an objective lens focusing the electron beam on the sample, the objective lens being selectively configurable to an out-lens mode or a semi-in-lens mode;\n the neutral particle beam column is able to selectively irradiate the neutral particle beam or an ion beam generated by ionizing the neutral particle beam; and the composite beam apparatus further comprises a beam irradiation setting means irradiating the ion beam from the neutral particle beam column when the objective lens is set to the out-lens mode.
