More Information
Summary:A cleaning solution production system is for cleaning a semiconductor substrate. The system includes a pressure tank, a plasma reaction tank configured to form a plasma in gas bubbles suspended in a decompressed liquid obtained from the pressure tank to thereby generate radical species in the decompressed liquid, a storage tank configured to store a cleaning solution containing the radical species generated in the plasma reaction tank, and a nozzle configured to supply the cleaning solution from the storage tank to a semiconductor substrate.
