  • Patent number: 11086118
    Abstract: Systems and methods for autofocusing an objective lens in a microscope system. A self-calibrating autofocus system includes a light source, a decentered aperture, and image-capturing device. The system may be connected to the microscope system so that the light source generates a light on an optical path that includes the objective lens and a plate having a reference surface proximal to a sample holding component. The image capturing device images a reflection of light from the reference surface as the objective lens moves to a series of z-positions. A reference calibration slope is generated for the objective lens by determining positions of the images taken at the z-positions of the objective lens. At least one image having a particular attribute corresponds to a best focus position. The objective lens is moved to predicted best focus or preferred offset from calibrated best focus using the reference calibration slope.

  • Patent number: 10613312
    Abstract: Scanned illumination allows for capturing 3-dimensional information about an object. A conventional reflection (or transmission) bright field (or fluorescence, darkfield, polarizing, phase contrast or interference) microscope is configured to use laterally scanned illumination (for example by moving an array in front of the light source) to scan an extended object. A pixelated detector may capture a series of images at the exit pupil of a microscope objective, and this series of images may be processed to form a Light Field image of the object. Or, a microscope is configured to provide scanned illumination to an extended object, while applying extended depth of field and 3D depth localization encoding to the resulting set of images. Thus multiple encoded images are generated. These images are decoded and combined, with custom digital signal processing algorithms, to form a 3D volume rendering or animation.

  • Patent number: 10402963
    Abstract: Defect detection on transparent or translucent wafers can be performed on a die using references from the same die. A first calculated value based on a kernel size, such as a moving mean, is determined. A first difference is determined by subtracting the first calculated value from a pixel intensity. Candidate pixels with a first difference above a threshold are classified. A second calculated value based on a kernel size, such as a local median, is determined. A second difference is determined by subtracting the second calculated value from the pixel intensity. Pixels that include a defect are classified when the second difference is above the threshold.

  • Patent number: 10298833
    Abstract: In the image capturing apparatus, the optical path difference producing member is disposed on the second optical path. Thereby, the amount of light for imaging an optical image which is focused at the front of an optical image made incident into the first imaging device (front focus) and an optical image which is focused at the rear thereof (rear focus) by the second imaging device can be suppressed to secure the amount of light on image pickup by the first imaging device. Further, in the image capturing apparatus, at least one of a position of the first imaging region and a position of the second imaging region on the imaging area is changed, thus making it possible to easily adjust an interval between the front focus and the rear focus. It is, thereby, possible to detect a focus position of the sample at high accuracy.

  • Patent number: 10217605
    Abstract: One embodiment relates to a method of automated inspection of scattered hot spot areas on a manufactured substrate using an electron beam apparatus. A stage holding the substrate is moved along a swath path so as to move a field of view of the electron beam apparatus such that the moving field of view covers a target area on the substrate. Off-axis imaging of the hot spot areas within the moving field of view is performed. A number of hot spot areas within the moving field of view may be determined, and the speed of the stage movement may be adjusted based on the number of hot spot areas within the moving field of view. Another embodiment relates to an electron beam apparatus for inspecting scattered areas on a manufactured substrate. Other embodiments, aspects and features are also disclosed.
