Claim Text:
1. A charged particle beam device comprising: a charged particle source; an objective lens configured to focus a charged particle beam emitted from said charged particle source onto a sample; a detector configured to detect secondary charged particles to be emitted from said sample; a probe capable of coming into contact with said sample; a gas nozzle configured to emit a conductive gas to said sample; and a control unit configured to control driving of said probe and gas emission from said gas nozzle, wherein said control unit has a contact detection unit, wherein after having applied processing by irradiating the charged particle beam to said sample so as to separate a part of said sample as a micro-sample, a conductive film is formed on said micro-sample by emitting the gas from said gas nozzle toward said micro-sample and simultaneously irradiating said charged particle beam prior to fastening one surface of the micro-sample processed by said probe on a sample table, and wherein said contact detection unit detects electrical conduction between said micro-sample and said sample table.
