    摘要: A rinse tank for rinsing electronic substrates after a chemical process and a method for utilizing such rinse tank are provided. In the rinse tank, devices for performing a quick dump rinse; for performing a cascade overflow rinse and for feeding an inert gas bubbling are provided in the cavity of a single rinse tank. By utilizing the present invention novel rinse tank, the processing problems frequently observed in conventional rinse tanks where two rinse tanks are required for the quick dump rinse and for the cascade overflow rinse, such as particle re-deposition and a large floor space area requirement are eliminated. Furthermore, the wafer rinse process after a metal etching process can be accomplished in a total process time that is at least 2˜3 minutes shorter than that required by using conventional rinse tanks.
