  • Patent number: 8946631
    Abstract: A substrate is irradiated by primary electrons and secondary electrons generated from the substrate are detected by a detector. A reference die is placed on the stage to obtain a pattern matching template image including feature coordinates of the reference die. A pattern matching is performed with an arbitrary die in a row or column including the reference die using the template image to obtain feature coordinates of the arbitrary die. An angle of misalignment is calculated between the direction of the row or column including the reference die and one of the directions of movement of the substrate on the basis of the feature coordinates of the arbitrary die and those of the reference die. The stage is rotated to correct the angle of misalignment to conform the direction of the row or column including the reference die with the one of the directions of movement of the substrate.

  • Patent number: 8920963
    Abstract: A portable device, which performs wireless communication with a communication peer, includes a battery, which powers an electronic component, and a case, which accommodates the electronic component and battery. The case includes a battery compartment having an opening. An elastic waterproof seal surrounds the opening. A battery lid, which covers the opening, is formed integrally with the waterproof seal and coupled to the case in a direction perpendicular to a radial direction of the waterproof seal. A rim around the opening of the battery compartment pushes the waterproof seal when coupling the battery lid to the case thereby elastically deforming the waterproof seal in an inward radial direction. The waterproof seal, when elastically deformed, keeps the battery lid coupled to the case and seals the battery lid and case in a liquid-tight state.
