  • Publication number: 20240144467
    Abstract: A hot spot defect detecting method and a hot spot defect detecting system are provided. In the method, hot spots are extracted from a design of a semiconductor product to define a hot spot map comprising hot spot groups, wherein local patterns in a same context of the design yielding a same image content are defined as a same hot spot group. During runtime, defect images obtained by an inspection tool performing hot scans on a wafer manufactured with the design are acquired and the hot spot map is aligned to each defect image to locate the hot spot groups. The hot spot defects in each defect image are detected by dynamically mapping the hot spot groups located in each defect image to a plurality of threshold regions and respectively performing automatic thresholding on pixel values of the hot spots of each hot spot group in the corresponding threshold region.

  • Publication number: 20240123511
    Abstract: A cutting tool with through coolant has an elongated shank and a cutting portion. The cutting portion is configured to remove material from a workpiece by cutting. An outer peripheral surface of the shank is configured to be surrounded and tightly held by a hole-wall defined by a tool-fixing hole of a machine tool. At least one coolant-guiding recess is formed in the outer peripheral surface of the shank and extends along a lengthwise direction of the shank. Each coolant-guiding recess forms a coolant channel together with the hole-wall of the tool-fixing hole. An end of the coolant channel is connected to a coolant-supply system. The coolant channel formed by the coolant-guiding recess enables coolant from the coolant-supply system to be jetted toward the cutting portion. The cutting tool provides through coolant without drilled holes, thereby saving cost.

  • Patent number: 9979952
    Abstract: A method for creating a parallax video from a still image includes following steps. Image segmentation is performed for separating at least a foreground object within the still image from an image background of the still image. A blank region of the image background is filled, and the blank region corresponds to where the separated foreground object locates within the still image. A virtual three-dimensional (3D) scene consisting of the foreground object and the image background is created. The virtual 3D scene is analyzed for determining a camera path; and, creating the parallax video by observing the virtual 3D scene with a virtual camera moving along the camera path.
