    Abstract: PROBLEM TO BE SOLVED: To provide a composite converging ion beam device capable of performing an observation of high resolution and fine processing, and a processing observation method and a processing method using the same.SOLUTION: A composite converging ion beam device includes a first ion beam irradiation system (10) including a liquid metal ion source generating first ions, and a second ion beam irradiation system (20) including a gas field ion source generating second ions. A second ion beam (20A) emitted by the second ion beam irradiation system (20) has a smaller beam diameter than that of a first ion beam (10A) emitted by the first ion beam irradiation system (10). The second ion beam irradiation system (20) including the gas field ion source can reduce the beam diameter to 1 nm or less, and so an observation of high resolution can be made.
