Publication number: 20230059414Abstract: 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.Type: ApplicationFiled: February 5, 2020Publication date: February 23, 2023Applicant: Hitachi High-Tech CorporationInventors: Hiroshi OINUMA, Kazuki IKEDA, Wen LI, Masashi WADA
