A transport container for wafer-shaped objects to keep particles away from and remove them from the interior of the transport container when opening the latter, in particular also those particles located in the door gaps, without restricting handling. Cleaning in the form of a self-cleaning process should also be effective when a plurality of transport containers are stacked one on top of the other and the latter should be optionally accessible. At least parts of the rear wall region of a closable container enclosure are constructed as a plenum chamber which has a closable air inlet and a closable air outlet in the base region and cover region, and a connection is formed from the latter to the interior of the container via a filter. The air inlet is constructed so as to complement a connection of a gas reservoir and an air outlet of an additional transport container for coupling. The arrangement is applicable in the manufacture of integrated circuits.
In a transport container for wafer-shaped objects in which a container enclosure is made up of two lateral regions which are located opposite one another and have projections forming shelves for receiving objects, a base region, a cover region, and a rear wall region, wherein an opening for removing and charging which is located opposite the rear wall region can be closed by a container door and removal and charging are effected in a plane parallel to the surface of the objects, the improvement comprising:
