Patent ID: 8562273

Claim:
A load port apparatus, which is to be attached to an attachment surface of a semiconductor processing apparatus, the attachment surface being provided with an opening portion for insertion and removal of an object-to-be-processed, and which opens and closes a lid of a pod as a sealed container arranged on an outside of the semiconductor processing apparatus with respect to the attachment surface so that the object-to-be-processed is insertable into and removable from an inside of the pod through the opening portion, the load port apparatus comprising: a main base which is formed of a plate-like body and is to be arranged in such a manner as to project while maintaining a predetermined angle with respect to the attachment surface of the semiconductor processing apparatus; a connecting plate which is fixable to the attachment surface, for coupling the main base and the attachment surface to each other by being fastened to the main base so as to maintain the predetermined angle; a placing table which is directly connected to and supported by the main base and on which the pod is to be placed; a door which is capable of holding the lid of the pod, for opening and closing the opening portion from an interior side of the semiconductor processing apparatus with respect to the attachment surface; and a door drive mechanism which is directly connected to and supported by the main base, supports the door, and makes the door open and close the opening portion, wherein the door drive mechanism is fixed to a main surface of the main base, the main surface being elongated in a plane parallel to a plane including a moving direction of the door at a time when the door drive mechanism makes the door open and close the opening portion, wherein the main base includes a first and second main base, wherein an inner surface of the first main base faces an inner surface of the second main base, and wherein the load port apparatus further comprises a coupling shaft extending between the inner surfaces of the first and second main bases for coupling the multiple main bases integrally with each other.
