  • Patent number: 11977219
    Abstract: An optical correction is predictively performed based on a result of AI learning previously performed by use of learning data including measurement data. The optical compensation system is provided with wavefront correction optics, a sensor and a controller. The wavefront correction optics corrects a wavefront of light that passes through a given optical path. The sensor obtains environmental information in the optical path. The controller calculates, based on the environmental information, a predicted wavefront disturbance of the light that has passed through the optical path and controls the wavefront correction optics so as to cancel the predicted wavefront disturbance.

  • Publication number: 20230343549
    Abstract: The present invention overcomes a trade-off between throughput, SNR, and spatial resolution in a charged particle beam device. Accordingly, a computer 18 sets at least one of a charged particle optical system and a detection system so as to modulate the intensity of signal charged particles or an electromagnetic wave detected by a detector 12 at a prescribed frequency. The charged particle optical system scans a specimen with a charged particle beam. The computer 18 generates an image or a signal profile by associating an irradiation position of the charged particle beam with a DC component of a signal acquired through synchronous detection of a detection signal from the detector at the irradiation position with a reference signal having a prescribed frequency.

  • 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.
