A method of removing small particles remaining on a surface of a semiconductor wafer and preventing a silicide layer covering the semiconductor wafer from corroding starts by controlling a temperature of the semiconductor wafer to between room temperature and 45° C. Then, a cleaning solution of a temperature between 0° C. and 45° C. is utilized to clean the semiconductor wafer to effectively remove small particles remaining on the surface of the semiconductor wafer and prevent the silicide layer from corrosion by the cleaning solution. Therein, the cleaning solution is comprised of a pre-determined volume ratio of hydrogen peroxide (H2O2), ammonia (NH4OH), and deionized water.
