    摘要: In a load port apparatus, a slit is formed between an inner circumferential surface of an opening on a wall of the chamber of the apparatus and an outer circumferential surface of a door. In a predetermined section of the slit, the slit width at the chamber side opening of the slit is made larger than the slit width at other positions with respect to the depth direction of the slit. By this feature, gas flow from the interior of the load port apparatus to the exterior through a clearance formed between the inner surface of the opening that allows to bring wafers out of/into a pod and the door that substantially closes the opening can be made stable.
