  • Liquid feed nozzle, wet treatment apparatus and wet treatment method
    Patent number: 6517635
    Abstract: The wet treatment liquid feed nozzle of the invention comprises an introducing path having an introducing port, a discharging path having a discharging port, a crossing section formed by causing the introducing path and the discharging path to cross at the other ends thereof, a nozzle assembly having an opening section opening to an object to be treated, provided at the crossing section, and pressure control means, for controlling the difference between the pressure of the wet treatment liquid in contact with the object to be treated and the atmospheric pressure provided at least on the discharging path side so that the wet treatment liquid having been in contact with the object to be treated via the opening section does not flow to outside the discharging path.
    Type: Grant

  • Cleaning method and apparatus for the same
    Patent number: 6039815
    Abstract: An aqueous oxidizing acidic cleaning solution or an aqueous oxidizing alkaline cleaning solution is produced by mixing an acidic or alkaline solution with ozone water. An aqueous reducing acidic cleaning solution or an aqueous reducing alkaline cleaning solution is produced by mixing an acidic or alkaline solution with hydrogen water. Each of these aqueous cleaning solutions has effective cleaning power and the ORP and pH values thereof are separately controlled. Therefore, by selecting an appropriate aqueous cleaning solution according to the types of contaminants adhering to subjects during each manufacturing step, a plurality of types of contaminants can be removed by washing with one type of aqueous cleaning solution.
