  • Patent number: 7767006
    Abstract: Water vapor is mixed to O3 gas generated by an ozone generator of discharge type. The mixed fluid is cooled by a cooler, thereby impurities such as metals and nitrogen oxides contained in the O3 gas dissolve into condensed water. Subsequently, a gas-liquid separator separates the O3 gas from the condensed water. Water vapor is mixed with the O3 gas again. The mixed fluid passes through a metal trap composed of a container containing plural silicon chips as a metal adsorbent, thereby to remove the remaining metals therefrom.

  • Patent number: 7731799
    Abstract: A substrate processing method which removes an ArF resist film from a wafer having the ArF resist film. As an ultraviolet irradiation process is performed on the ArF resist film, and then an ozone gas and water vapor are fed to the ArF resist film, the ArF resist film is altered in a water-soluble state. Thereafter, the ArF resist film is removed from the substrate by feeding pure water to the ArF resist film altered into the water-soluble state.
