  • Publication number: 20250014859
    Abstract: The present invention provides a computer, a program, and a charged particle beam processing system, with which it is possible to reduce adjustment and setting work of conditions for observation or machining by an operator in an FIB-SEM composite device. This computer comprises: an information acquisition unit that acquires information related to a recipe to be executed by a charged particle beam device provided with a charged particle irradiation optical system; and an information management unit that generates recipe management information based on the information acquired by the information acquisition unit and stores the recipe management information in a storage unit.

  • Patent number: 11742177
    Abstract: Automated processing is provided. A charged particle beam apparatus includes: an image identity degree determination unit determining whether an identity degree is equal to or greater than a predetermined value, the identity degree indicating a degree of identity between a processing cross-section image that is an SEM image obtained through observation of a cross section of the sample by a scanning electron microscope, and a criterion image that is the processing cross-section image previously registered; and a post-determination processing unit performing a predetermined processing operation according to a result of the determination by the image identity degree determination unit.
