ABSTRACT:
A cleaning system (1, 5) having multiple cleaning chambers (200) is provided. Each cleaning chamber (200) includes an interior region sufficient for immersing a carrier (242), which has at least one wafer disposed therein, into an ultra-clean liquid. The cleaning chamber (200) also has an inlet operably coupled to the interior region to introduce a gas into the interior region and a drain operably coupled to the interior region to remove the ultra-clean liquid from the interior region at a selected rate. A controller 14 is operably coupled to the chamber (200) for selectively controlling the selected rate. In an alternative embodiment, an installation technique (80) for the above cleaning system (1, 5) is provided.
