  • Patent number: 11610754
    Abstract: An object of the invention is to provide a charged particle beam device capable of specifying an irradiation position of light on a sample when there is no mechanism for forming an image of backscattered electrons. The charged particle beam device according to the invention determines whether an irradiation position of a primary charged particle beam and an irradiation position of light match based on a difference between a first observation image acquired when the sample is irradiated with only the primary charged particle beam and a second observation image acquired when sample is irradiated with the light in addition to the primary charged particle beam. It is determined whether the irradiation position of the primary charged particle beam and the irradiation position of the light match using the first observation image and a measurement result by a light amount measuring device.

  • Publication number: 20230056978
    Abstract: In a mass spectrometer, due to impurities accumulated inside a frame, a withstand voltage may decrease, and electric discharge may occur in an ion source, thereby making it impossible to perform normal measurement. Since a result of abnormality measurement due to the electric discharge cannot be distinguished from measurement abnormality caused by clogging of a tube between a pretreatment unit and a needle, there is a problem in that time is required to identify abnormal portions, and a maintenance property is lowered. As a unit for solving the problem, a return current detection unit connected in series between the frame and an ion source power supply that applies a voltage to the needle and a return current detection unit connected in series between the frame and a counter electrode power supply that applies a voltage to a counter electrode are provided.

  • Publication number: 20230059414
    Abstract: A method of setting a parameter of a charged particle beam device, for shortening the time required to adjust an ABCC parameter. An inverse conversion processing unit generates a simulator input signal corresponding to an electron emitted from a sample. A simulation detector uses an arithmetic model that simulates a detector and executes arithmetic processing on the simulator input signal in a state in which characteristic information is reflected in an arithmetic parameter. A simulated image conversion unit executes arithmetic processing corresponding to an image conversion unit and converts a signal from the simulation detector into a simulated image. An ABCC search unit searches for an ABCC parameter with respect to the simulation detector so that an evaluation value obtained from the simulated image becomes a specified reference value, and outputs the ABCC parameter as a search result to an ABCC control unit of the actual machine.
