Abstract
The present invention provides a semiconductor fabrication process and cluster tool utilizing individual gas boxes for each of the processing chambers. These individual gas boxes provide an enclosure where groupings of related gas components may be positioned above and/or adjacent to the semiconductor processing chamber requiring those objects or components. The proximity of the individual gas boxes to the respective processing chambers facilitates the delivery of gases to the chamber as needed. Furthermore, the individual gas panels enable a modular design comprising a processing chamber and gas panel combination. This modular design allows individual chambers and their respective gas panels to be run through various pre-installation tests.
