Abstract: An ultrasonic inspection device is used for inspecting a packaging container having a joined portion including overlapping and joined edges of the packaging container. The ultrasonic inspection device includes a transmitter configured to irradiate ultrasonic waves toward at least a base end portion of the joined portion in a state in which the joined portion protrudes from a surface of an object in a direction orthogonal to the surface, the base end portion being positioned on a side of the object. The ultrasonic inspection device further includes a plurality of receivers configured to receive the ultrasonic waves transmitted through the joined portion.

Abstract: A photomask with a dummy pattern is inspected in a predetermined detection sensitivity by using photomask pattern data designating a photomask with a dummy pattern to detect defects in the photomask. Coordinates indicating the positions of the defects are also determined. The defects in a design pattern area and those in a dummy pattern area are discriminated by using defect-discriminating data. The defects in the design pattern area and those in the dummy pattern area are examined on the basis of respective inspection specifications.

Abstract: Substrate-selecting equipment selects substrates used for objective products from among a group of substrates with photosensitive material layers used for the production of photomask. The substrate-selecting equipment comprises one or more of the defect-registering part(s) for registering the results of the inspection of defects of substrates with photosensitive material layers in database, the photosensitive material layer lot check result-registering part for registering the results of check of lots of photosensitive material layers in database and the substrate-selecting part for selecting substrates used for the production of objective products from among a group of substrates with photosensitive material layers, on the basis of the results of inspection of defects and the results of check of lots of photosensitive materials registered in database.
