Abstract:
A method of removing particles adhering to a surface of a semiconductor wafer comprising the sequential steps of:a) providing a container having a drain valve;b) positioning said semiconductor wafer in said container;c) initially directing a first jet stream consisting of water against said surface of said semiconductor wafer;d) then, after said initially directing said first jet stream against said surface of said semiconductor wafer commences, removing particles adhering to said surface of said semiconductor wafer by scrubbing said surface of said semiconductor wafer with a brush while said first jet stream of water continues to be directed against said surface of said semiconductor wafer;e) closing said drain valve while said first jet stream of water is directed against said semiconductor wafer, wherein said water accumulates in said container to thereby completely immerse said brush and said semiconductor wafer in said water in said container;f) maintaining said brush and said semiconductor wafer completely immersed in said water from said first jet stream for a predetermined period of time;g) then moving said brush out of contact with said surface of said semiconductor wafer; andh) then rinsing said surface of said semiconductor wafer.
