  • Patent number: 6529619
    Abstract: The present invention provides data analysis stations respectively for a probing tester and an automatic particle inspection machine. And in the data analysis station, the coordinates on which the disposition of the chips are described on a product basis are equal to those on which the locations of the defects are described. Further, the station provides a function of determining which of the chips each defect belongs to. These data analysis stations are connected through a communication line. The present invention is capable of analyzing the data on a chip basis, resulting in being able to grasp the relation between how the defects are caused on each chip and the product character of the chip.

  • Patent number: 6390145
    Abstract: A clean box has a container including a container body opened at one surface and a lid for closing the opening of the container body. An annular groove is formed in at least one of the container body and the lid so as to surround the opening. An elastic seal member is disposed within the annular groove along its whole length. A cross-section in a width direction of the elastic seal member has relatively thick end portions and a relatively thin intermediate portion in its dimension in a depth direction of the annular groove. Thus, when the lid closes the opening of the container body, an annular suction space is defined along the intermediate portion of the seal member. Also, the suction space is sealed by elastic deformation of the both end portions of the seal member between the container body and the lid. Further, the clean box has an intake/exhaust port mechanism for evacuation/release of the suction space from the outside.

  • Patent number: 6338604
    Abstract: A latch mechanism for latching a lid of a clean box having a box body opening at one surface and a lid for closing the opening includes a latch member pivotal about a shaft mounted on the box body, a latch engagement portion provided on the lid for engaging with the latch member in its predetermined pivotal position, and a biasing member for biasing the latch member toward the latch engagement portion. A guide surface is provided in a portion, facing outwardly, of the opening of the box body of the latch member. When the clean box is installed on a load port, the guide surface is brought into a pressing contact with the latch guide provided in the load port so that the latch member pivots to release the latch of the lid.
