Degassing apparatus adapted to process substrates in multiple tiers with second actuator

Abstract

Substrate transport systems, apparatus, and methods are described. In one aspect, the systems are disclosed having vertically stacked transfer chamber bodies. In one embodiment, a common robot apparatus services process chambers or load lock chambers coupled to upper and lower transfer chamber bodies. In another embodiment, separate robot apparatus service the process chambers and/or load lock chambers coupled to upper and lower transfer chamber bodies, and an elevator apparatus transfers the substrates between the various elevations. Degassing apparatus are described, as are numerous other aspects.
