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 3):
The composite beam apparatus of  claim 1 , wherein a distance L 1  between an apex of the electron beam column and irradiation point (P), a distance L 2  between an apex of the focused ion beam column and the irradiation point (P), and a distance L 3  between an apex of the neutral particle beam column and the irradiation point (P) satisfy a relationship of L 1 <L 2 <L 3 .
