Wet process for semiconductor device fabrication using anode water containing oxidative substances and cathode water containing reductive substances, and anode water and cathode water used in the wet process
A wet process performed in the manufacture of semiconductor devices with cathode water and anode water produced from electrolyte using a 3-cell electrolyzer having an intermediate cell for the electrolyte. The 3-cell electrolyzer includes an anode cell, a cathode cell, and an intermediate cell between the anode and cathode cells, which are partitioned by ion exchange membranes. Deionized water is supplied into the anode and cathode cells, and the intermediate cell is filled with an electrolytic aqueous solution to perform electrolysis. The anode water containing oxidative substances or the cathode water containing reductive substances, which are produced by the electrolysis process, are used in the wet process.
