A method and apparatus for processing substrates in a cluster tool is disclosed. The transfer chambers of the cluster tool have eight locations to which additional chambers (i.e., load lock, buffer, and processing chambers) may attach. The transfer chamber may be formed of three separate portions. The central portion may be a rectangular shaped portion. The two other portions may be trapezoidal shaped portions. The trapezoidal shaped portions each have three slots through which the substrate can move for processing. The central portion of the transfer chamber may have a removable lid that allows a technician to easily access the transfer chamber.
