Abstract:
1. A semiconductor manufacturing system adapted to handle a wafer, the semiconductor manufacturing system comprising: a plurality of vertically stacked loading stations; a shared vacuum environment coupled to the loading stations; a plurality of process modules arranged in a linear system and sharing the shared vacuum environment, wherein the shared vacuum environment has a loading end and an exit end disposed at opposite ends of the linear system, the plurality of process modules being vertically stacked process modules that are arranged in at least a two-level configuration having a top level and a bottom level; and at least two transfer chambers adjacently arranged in the linear system where the top and bottom level are joined by the adjacent transfer chambers, the top level of each transfer chamber including a pair of process modules rotated substantially forty-five degrees relative to the bottom level such that the pair of process modules on the top level of one of the transfer chambers has a substantially opposing arrangement to the pair of process modules on the top level of another one of the transfer chambers.
