  • Patent number: 11969844
    Abstract: A method for detecting and compensating CNC tools being implemented in an electronic device, receives from a detector first parameters and second parameters in respect of a first tool. Such first parameters include at least one of service life, blade break information, and blade chipping information of the first tool, and such second parameters include at least one of length extension information, length wear information, radial wear information, and blade thickness wear information of the first tool. Based on the first parameters, instructions to process the workpiece are transmitted or not. Upon receiving the second parameters, instructions to adjust operation of the first tool are transmitted, to compensate for deterioration in normal use.

  • Patent number: 8805054
    Abstract: A method of classifying the defects on a wafer having some same chips and corresponding system is provided. After receiving images formed by scanning the wafer using a charged particle beam, these images are examined such that both defective images and defect-free images are found. Then, the defect-free images are translated into a simulated layout of the chip, or a database is used to provide the simulated layout of the chip. Finally, the defects on the defective images are classified by comparing the images with the simulated layout of the chip. The system has some modules separately corresponds to the steps of the method.

  • Patent number: 8068662
    Abstract: A method for determining a defect during charged particle beam inspection of a sample locates at least one examination region within a charged particle microscopic image of the sample by making reference to a database graphic of the sample corresponding to the charged particle microscopic image. Each located examination region concerns at least one element of the sample, and each element has at least one characteristic in common. At least one point response value is then generated for each point in the located examination regions. The presence of a defect at the location of the concerned point is then determined by applying at least one decision tree operator to the generated point response values of the concerned point. Applications of the proposed method as a computing agent and a charged particle beam inspection system are also disclosed.
