发明名称 Process for cleaning a semiconductor wafer using a cleaning solution
摘要 Semiconductor wafers are cleaned using a cleaning solution containing an alkaline ammonium component in an initial composition, wherein the semiconductor wafer is brought into contact with the cleaning solution in an individual-wafer treatment, and in the course of cleaning hydrogen fluoride is added as further component to the cleaning solution, and the cleaning solution has at the end of cleaning, a composition that differs from the initial composition.
