Abstract

A load lock is provided for a semiconductor substrate processing system having a transport robot mounted therein. The load lock transport supplies substrates directly to a processing chamber without the need for a central transport robot. The load lock transport is a dual element robot designed for minimum clearance and space and operates within a matching load lock chamber of minimum volume.
