发明名称 Wafer cleaning method
摘要 A method is provided for cleaning a surface of a wafer. First, the wafer is placed in a closed cleaning chamber, and then a cleaning agent is infused into the cleaning chamber to a predetermined height, so that the wafer is completely immersed in the cleaning agent. Next, the pressure in the cleaning chamber is lowered to a sub-atmospheric state of 0.1 to 0.5 atm with a vacuum pump, and then returned to the normal value to complete the cleaning process.
