Abstract: The present invention generally provides a system for processing substrates having a carrier disposed primarily in at least one processing chamber and at least one shuttle for transferring substrates between the processing chamber and a load lock chamber. A plurality of processing chambers, load lock chambers, and other chambers can be joined to create a series of modular chambers through which the substrates are processed. Preferably, the carrier is only exposed to the processing environment, i.e., the carrier does not shuttle into a non-processing chamber. Thus, during continuous sequential processing of substrates, thermal cycling of the carrier is reduced. The carrier is reversibly moved within the processing chamber along a track. Multiple processing zones separated by partitions allow a plurality of processing regimes to occur within the same processing chamber.

At least one temperature controlled plate positioned in the processing environment is selectively in communication with the at least one substrate carrier and is used to both transfer substrates from an external substrate shuttle to the substrate carrier in the processing environment and to regulate the temperature of the processing environment. At least one deposition device configured to deposit a selected film on the substrate and an annealing device are positioned proximate the at least one substrate carrier within the processing environment.
