Wafer support shelves (10, 10) are each provided with wafer support projections (A, B1, B2) on which parts of the outer margins of a semiconductor wafer (W) are to be placed. In each case, one of the support projections (A, B1, B2) is provided on the far side of the center position of the semiconductor wafer (W), and two of the support projections are provided on the near side of the center of the semiconductor wafer. By means of this structure, in a state in which a lid body (3) is not attached to a wafer extraction/insertion opening (2), the flexure amount of the semiconductor wafers placed on the support projections of multiple locations in the wafer support shelves can be reduced with a minimal number of projections, so that a hindrance is not created to an operation such as extraction by a robot arm.

A substrate storing container includes: a container body for storing semiconductor wafers; a door that is fitted to the front of the container body; and a locking mechanism locking the door. The locking mechanism includes: a rotary driver that is supported by the door and operated from a cover plate side; and a locking bar that vertically slides as the rotary driver rotates to bring the distal end into, and out of, a locking hollow of the container body. The rotary driver is separated into first and second rotary drivers. The first and second rotary drivers are formed with first and second cam portions, respectively. The first and second cam portions are made to support the proximal end of the locking bar therebetween so that the locking bar can sway in the thickness direction of the door.

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.

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.

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.
