ABSTRACT:
A method for cleaning a semiconductor silicon wafer, which can suppress and reduce adhesion of particles to the surface of the wafer, is disclosed. The method includes the steps of cleaning the semiconductor silicon wafer by using hydrofluoric acid aqueous solution containing a surfactant, and thereafter rinsing the semiconductor silicon wafer by using pure water containing ozone.
