Abstract

Apparatus for multi-chambered semiconductor wafer processing comprising a polygonal structure having at least two semiconductor process chambers disposed on one side. An area between the process chambers provides a maintenance access to the semiconductor processing equipment. Additionally, the apparatus may be clustered or daisy-chained together to enable a wafer to access additional processing chambers without leaving the controlled environment of the semiconductor wafer processing equipment.
