  • 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.

  • Patent number: 6716346
    Abstract: A fluid magnetizer having magnets that are arranged at the two sides of the route of the fluid. Two magnets are arranged on one side such that the N-pole of both magnets are faced toward each other and joined to form a N-magnetic packet, and two magnets are arranged at the other side such that the S-pole of both magnets are faced toward each other and joined to form a S-magnetic flux. Through the attraction caused by the opposite magnetism of the magnetic fluxes at the two sides, magnetic lines of forces having stronger strengths are generated and then linearly penetrated through the section of the fluid. Therefore, the fluid is fully magnetized when passing through the magnetizing segment, thereby increasing the magnetization efficiency of the fluid.

  • Patent number: 6377147
    Abstract: The present invention comprises two magnets and two “T” shaped metal plate structures, magnets placed between the protruding sections of the metal plates, so that the said magnets fit into the indented space made by the two protruding sections, and, moreover, the poles of the two magnets are placed so that each pole faces a pole with the same magnetic pole, and the inner curved area of protruding sections of the metal plates is made to fit against the piping. Because each of the metal plates is fitted with magnets with differing magnetic poles, the magnetic field is able to more effectively penetrate the piping, so that when the liquid is flowing in a lengthwise motion through the area of the magnetizer, the effectiveness of the magnetization process is increased.
