  • Publication number: 20070264105
    Abstract: A combination load lock apparatus is provided, wherein a chamber is coupled to two or more valves in selective fluid communication with two or more respective volumes. A support member for supporting a workpiece is disposed within an interior portion of the chamber, wherein a translation apparatus is operably coupled thereto. The translation apparatus is operable to rotate and/or translate the workpiece on the support member about and/or along a first axis, wherein a detection apparatus associated with the chamber is operable to detect one or more characteristics of the workpiece during the rotation and/or translation thereof. The workpiece may be further rotated in a predetermined manner based on the one or more detected characteristics. A recess is further defined in the interior portion of the chamber, wherein the translation apparatus is operable to translate the workpiece into and out of the recess to reduce particulate contamination thereon.
