Wafer cleaning apparatus and wafer cleaning method using the same

Abstract

The object of the present invention is to provide a wafer cleaning apparatus that reduces the amount of dissolved oxygen, without using hydrogen peroxide, to be able to reduce the deformation, etc. of a wafer and to reduce silicon consumption and a wafer cleaning method using the same. The present invention provides a wafer cleaning apparatus comprising: a first thin film contactor that receives drug solution for removing an oxide film or ultra pure water to separate and discharge gas dissolved in the drug solution for removing the oxide film or the ultra pure water; a second thin film contactor that receives the drug solution for removing the oxide film or the ultra pure water discharged from the first thin film contactor; a vacuum pump that discharges gas separated in the first and second thin film contactors to the outside; and a process vessel that stores the drug solution for removing the oxide film or the ultra pure water discharged from the second thin film contactor, and a wafer cleaning method using the same.
