Claim Text:
1. A charged particle beam apparatus comprising: a charged particle source; a condenser lens electrode configured to condense a charged particle beam extracted from the charged particle source; a blanking electrode configured to switch irradiation and non-irradiation of the charged particle beam; a scanning electrode configured to scan and irradiate the charged particle beam; a sample stage on which a sample is to be mounted; a secondary charged particle detector configured to detect a secondary charged particle generated from the sample in response to irradiation of the sample with the charged particle beam; a reservoir in which a silicon compound represented by a general formula (I) below is accommodated as a source gas; and a gas gun configured to supply the source gas to a position of the sample that is irradiated with the charged particle beam, (where n is an integer of 3 or larger, m is an integer of n, 2n−2, 2n, or 2n+2, and X represents a hydrogen atom and/or a halogen atom).
