Abstract: A container or carrier for securely carrying a substrate such as a reticle, mask, wafer, or the like during a semiconductor manufacturing process or during the transport of the substrate. The container includes a housing having an opening through which the substrate may be inserted and removed. The housing includes an open box and a lid, the lid securely held in place by a unique latching mechanism. A door that is hinged upon the lid and held in place by biasing springs substantially seals the housing opening. Within the housing are a plurality of suction cups upon which the substrate rests and which apply suction to firmly engage the substrate on only one side when the substrate is in a contained position. The suction cups hold the substrate in the contained position thereby preventing relative motion between the container and the substrate.
