Patent ID: 7592606

Claim:
A charged particle beam processing apparatus, comprising: a sample holder that holds a sample; a stage that moves the sample holder; a vacuum vessel that encloses the sample holder and the stage; an ion generation source; an ion beam column that is connected to the vacuum vessel, takes out an ion beam of a nonmetallic ion species from the ion generation source and irradiates the sample with the ion beam; a microsampling unit having a probe that picks out a micro test piece cut out of the sample by an ion beam from the ion beam column; a gas gun that discharges a gas that bonds the micro test piece and the probe together; a pollution measuring beam column that is connected to the same vacuum vessel to which the ion beam column is connected and irradiates ion beam irradiation traces formed by the ion beam column with a pollution measuring beam, which is an electron beam or an X-ray beam; and a detector that detects a characteristic X-ray that is emitted from the ion beam irradiation traces formed by the ion beam column upon irradiation with a pollution measuring beam from the pollution measuring beam column, wherein an aiming position of an ion beam from the ion beam column and an aiming position of a pollution measuring beam from the pollution measuring beam column are spaced from each other and, in a state where the ion beam irradiation traces formed by the ion beam column are irradiated with a pollution measuring beam, the position of the sample holder is adjustable by driving the stage, whereby the ion beam irradiation traces are caused to coincide with the aiming position of a pollution measuring beam.
