SAT Dump Rinse
The system described in this patent is used in the semiconductor industry for the cleaning in deionized water
(DIW) of silicon wafers that are cleaned by the action of water from previous cycles of treatment with acids or
solvents. The pool and facilities described below are all housed inside covers of process treatment with acids
or solvents.
This system allows two different methods (dump and overflow) for washing the wafer. In this patent are
introduced, the systems already in use, two significant changes, aimed at improving the processes. The first
option allows you to enrich the water with nitrogen and is translated into practice through substantial
modification of the discharge valve and the other is, during the various stages of washing, the rotation of the
wafer carrier
