Abstract:
A method of making a transport chamber configured to receive a robot arm installed within the transport chamber, the robot arm being implemented to retrieve a substrate from at least one storage facility that is external to the transport chamber, and insert the substrate into at least one processing chamber that is external to the transport chamber, the method of making the transport chamber comprising:providing a bottom plate having an inner surface;defining a robot drive mounting port at about a center of the bottom plate;applying a first o-ring seal around the perimeter of the inner surface of the bottom plate;generating a chamber housing from a rolled forging that is a solid aluminum ring, the chamber housing having a top surface, and a bottom surface, the bottom surface being designed to meet the inner surface of the bottom plate such that the first o-ring seal forms a substantially vacuum-tight seal when the bottom plate is coupled to the chamber housing bottom surface;machining a plurality of facets around the chamber housing to facilitate the connection of multiple processing chambers and substrate storage facilities; andproviding a top plate having an underlip portion around a perimeter designed to sit over a second o-ring seal being applied around a perimeter of the chamber housing top surface such that a substantially vacuum-tight seal is formed between the top surface of the chamber housing and the top plate.
