Abstract:
An apparatus for washing glass substrates comprising:a cassette for holding a plurality of sheets of glass substrate, each glass substrate having thereon a transparent electrode, prior to irradiation with ultraviolet rays and for holding a plurality of irradiated sheets of glass substrate after irradiation; ultraviolet exposure means for irradiating said sheets of glass substrate with ultraviolet rays; holding means for moving a sheet of glass substrate from said cassette to said ultraviolet exposure means for irradiation and for moving an irradiated sheet of glass substrate from said ultraviolet exposure means back to said cassette; ultrasonic washing means consisting of a first ultrasonic cleaning vessel containing a liquid consisting of water for immersing the cassette to wash the plurality of irradiated sheets of glass substrate and a second ultrasonic cleaning vessel containing a liquid consisting of water for immersing the cassette to wash the plurality of irradiated and once-cleaned sheets of glass substrate, said second ultrasonic cleaning vessel disposed immediately adjacent to said first ultrasonic cleaning vessel; a drying vessel containing isopropyl alcohol for drying therein the plurality of sheets of glass substrate, said drying vessel disposed immediately adjacent to said second ultrasonic cleaning vessel; and conveying means for moving said cassette holding said plurality of irradiated sheets of glass substrate from said first ultrasonic cleaning vessel to said second ultrasonic cleaning vessel to said drying vessel in this order.
