Abstract: A main body may have a cavity for storing a plurality of parallel semiconductor wafers and an opening for transferring one or more semiconductor wafer into or from the cavity. A covering body may be mounted detachably to the opening in order to close the opening. A gasket may seal between an edge portion of the covering body and an edge portion of the opening. The gasket may be configured such that, when the opening is closed by the covering body, a size of a deformation margin of the gasket is formed to be smaller in a region that seals a vertical edge portion of the opening orthogonal to the face of each semiconductor wafer than in a region that seals a horizontal edge portion of the opening parallel to the face of each the semiconductor wafer.

Abstract: Arbitrary pieces of semiconductor wafers are supported flexibly on either the upper side or the lower side. The present invention is a thin plate container for supporting plural semiconductor wafers for use in carriage, storage, processing, etc. It comprises processing trays plurally stacked in a state of each supporting at least one semiconductor wafer individually and a coupling mechanism for integrally coupling the processing trays in a state where the processing trays are plurally stacked and separating the processing trays at an arbitrary location. Each processing tray has a one-side support for supporting at least one semiconductor wafer on its one side and the other-side support mutually fitted to the one-side support of the other processing tray on the other side to form a housing space sealed off from the external environment for constraining and supporting the thin plate.

Abstract: When a lid (20) is attached to a substrate removal/insertion opening (2) in a container body (1), a placement piece forcible displacement means (22) forcibly moves a substrate placement piece (4), which is provided in a region in the vicinity of the substrate removal/insertion opening (2), to a displacement position which does not overlap with a disc-shaped substrate (W). Thus, even if the disc-shaped substrate (W) is increased in diameter, there is no risk of the stored disc-shaped substrate (W) coming into contact with the substrate placement piece (4) due to factors such as vibration or impact, thus the disc-shaped substrate (W) can be stored more safely.

Abstract: Wafer protecting grooves (10) are provided on an innermost wall (1b) of a container body (1). The wafer protecting grooves have a cross-sectional configuration in the shape of undulations having bottoms (10b), which are most distant from an opening (1a), at respective positions facing the outer edges of semiconductor wafers (W), and having an opening width wider than the thickness of each semiconductor wafer (W). In a normal state, an imaginary line (Q) connecting together the tops of the undulations is inward of or at the same position as the outer edges of the semiconductor wafers (W) facing the imaginary line. Thus, it is possible to obtain superior impact resistance that makes the semiconductor wafers (W) in the container body (1) unlikely to be damaged even when a large impact is applied thereto by a fall or other handling errors.

Abstract: A wafer-retaining unit has a plurality of vertically superimposed single-wafer retaining sections, each having a wafer-retaining frame abutting against only a lower end edge portion of the outer periphery of a semiconductor wafer, a wafer-securing frame disposed vertically movably relative to the wafer-retaining frame to abut against only an upper end edge portion of the outer periphery of the semiconductor wafer, and wafer lift members that lift the semiconductor wafer to a position where it is upwardly separate from the wafer-retaining frame and keeps the semiconductor wafer in this position. Consequently, a plurality of semiconductor wafers can be accommodated efficiently and safely without increasing the space between each pair of mutually adjacent semiconductor wafers. At the same time, the semiconductor wafers can be loaded and unloaded satisfactorily.

Abstract: The position of a substrate temporal placement piece (4) is set so that the substrate temporal placement piece (4) does not overlap a disc-shaped substrate (W) from a viewing direction perpendicular to the surface of the disc-shaped substrate (W), when a lid (20) is attached to a substrate transfer opening (2) of a container main body (1) and the disc-shaped substrate (W) is pressed to a location where the substrate is positioned and held by a back side holding portion (3). Thereby, even if the disc-shaped substrate (W) stored in the container main body (1) is bent due to vibration, impact, etc., there is no danger that the substrate (W) is in contact with the substrate temporal placement piece (4), and the disc-shaped substrate (W) having a larger diameter can be safely stored.

Abstract: The dimensions of the deformation margins (Xh, Xp) of a gasket (8), in a state wherein an opening (2) for transferring a wafer into/from a container is closed with a covering body (5) and a gap between the end portion of the covering body (5) and the end portion of the opening (2) is sealed by means of the gasket (8), are formed smaller in a region which seals an end portion (2p) perpendicular to the surface of the semiconductor wafer (W) than those in a region which seals an end portion (2h) parallel to the surface of the semiconductor wafer(W), said regions being the parts of the end portion of the opening (2). Thereby the semiconductor wafer (W) is not contaminated due to dusts and the like sucked from the outside at a moment when the covering body (5) is opened.

Consequently, there is no likelihood of the semiconductor wafer being damaged during transport or the like. In addition, the wafer-retaining cushion sheet can be readily attached to and detached from the wafer tray for washing or replacement according to need.

Abstract: A laser light is irradiated on a wafer case made of polymer materials that have a high transparency to visible light and a low transparency to laser light having a wavelength other than the optical wavelength. The wafer case material in the irradiated portion foams, blackens, melts or evaporates by the irradiation. Thus, wafer case information can be marked by concavities and convexities or changing color formed on the wafer case surface. The wafer case information can be formed as a one-dimensional or two-dimensional code. Multiple laser lights can be irradiated on the same portion of the wafer case surface from different directions to the wafer case surface, and thus wafer case information is marked on only the neighborhood of the wafer case surface by foaming, blackening, melting or evaporating only the neighborhood of the wafer case surface that the laser light is irradiated on.

The control unit adjusts the force to retract the hook member on the basis of detection values of a thickness sensor, a position sensor, and a retracting force detection sensor.
